Abstract: A supporting bearing for resiliently supporting parts to be connected to one another, such as the body and rear axle housing of a motor vehicle, includes two bearing parts to be arranged on mutually opposite bearing surfaces of one part, coaxially to a bore traversing the latter. These bearing parts are each equipped with an annular elastomer element arranged between two supporting parts and can be clamped to the part in which the bore has been made using a clamping bolt traversing the bearing parts and the bore with radial clearance. The elastomer elements of the two bearing parts are, on the one hand, vulcanized to one of the supporting parts accommodating them between them and, on the other hand, rest on the other supporting part by an integrally formed surface region projecting at their free front face.

Abstract: In a filter insert which is received exchangeably in a shaft along a channel and which can be fixed sealingly relative to frame shaped shaft walls via at least one gasket preferably continuous on a flow-off side of the filter, it becomes possible to change the filter easily, without the danger of damaging the gasket, if there is at least one pressing element which can be connected to a pressure reducing device. When the pressing element is in the contracted pressure reduced position, a continuous gap forms between the gasket and associated shaft wall during a shift of the filter, this gap being cancelled when the pressure reducing device is disconnected.

Abstract: A fuel tank having two tank spaces spaced from one another and connected to one another at a distance above their bottom. One tank space is equipped at its bottom with a retaining vessel having a closed shell. To assure that both tank spaces are reliably emptied, each tank space is equipped with a jet pump charged with fuel via a supply line. Both of the jet pumps, which are parallel or series connected to each other, deliver fuel to the retaining vessel.

Abstract: An adjusting device is disclosed for the brake shoes of inside shoe brakes. The adjusting device includes two levers which are articulated on a carrier at a lateral distance from one another. The levers each engage on one of two adjacent brake shoe ends and are jointly in engagement with a frustoconical endpiece of an actuating member guided rotatably on the carrier in a threaded bore provided between the levers and extending in parallel with a brake drum axis. During the rotation of the actuating member for the adjustment of the brake shoes, the two levers are pivoted in directions opposite to one another, being supported respectively on one of two mutually opposite edges of the brake-shoe webs so as to surround these. The adjusting device is merely attached by its levers on to the brake shoe webs so it can also execute self-reinforcing floating movements of the brake shoes in dual servo-brakes.

Abstract: A self-supporting motor-vehicle body includes outer lateral side members (sills) on a substructure in the region of the passenger cell, and front and rear side members which are angularly offset relative to a longitudinal center axis of the vehicle and respectively located at a vehicle forward structure and at a vehicle rearward structure. The front and rear side members adjoin the lateral side members via a bent portion. In order to provide stiffening of the body, struts are secured to the substructure of the body so as each to be fastened at one end to a lateral side member, and directed towards a middle region of the vehicle with their other end fastened once again to the substructure of the body. A front strut is guided from each of the two lateral side members into the vehicle forward structure and/or a rear strut is guided from each of the two lateral side members into the vehicle rearward structure, with each strut preferably being aligned at an angle of approximately 45.degree.

In order to reduce the manufacturing costs and the overall size, the worm gear trains comprise worm gears consisting of the side gears and worms consisting of the differential pinions and the differential pinions of each pair have axes extending at an angle to each other and directly mesh with each other.

Abstract: A power-assisted steering method establishes or sets an auxiliary force by taking into account a plurality of variables such as transverse acceleration and vehicle speed characterizing the instantaneous driving conditions. The driving feel with regard to the state of the road surface and the instantaneous driving situation for the vehicle driver are thereby ensured.

Abstract: The invention relates to an exhaust-gas removal duct formed from individual axially mutually adjacent sections for track-forming lanes, having a longitudinal slot closed by a pair of elastic sealing lips. Each section has two channel-shaped shells which are joined leaktightly along a common longitudinal edge. One yoke sheet is, furthermore, provided per section, surrounds the section up to the longitudinal slot, transversely to the longitudinal axis of the removal duct, and is connected to the channel-shaped shells only in the region of the longitudinal edge and in the region of the sealing lips.

Abstract: A system for purifying the exhaust gases of a diesel engine comprises an exhaust gas line, which is branched to form two branch lines, which are adapted to be shut off in alternation by change-over valve means. One of said branch lines constitutes a filter line, which incorporates a soot filter. The other branch line constitutes a by-pass line. Downstream of the soot filter the filter line joins the by-pass line to form a common end line. In dependence on the load on the engine, the filter line is opened by the change-over valve means only during an operation of the engine under a full load or under a partial load in excess of a predetermined value. In order to ensure that the exhaust gas will almost entirely be purified during an operation of the engine throughout its load range, an diesel soot oxidation-inducing catalyst is provided downstream of the change-over valve means and is incorporated in the by-pass line or in the common end line.

Abstract: A motor vehicle with four driving wheels and driven differential gearing for the drive, where (in the case of rotational-speed differences occurring between the wheels) a control device intervenes to distribute the drive power of an engine to the permanently driven wheels and/or the other driven wheels. This intervention occurs for a particular holding time which is progressively extended if a new intervention by the control becomes necessary after a test disconnection of the respective intervention. In addition, or alternatively, the control device can respond more sensitively and thus more quickly to rotational-speed differences of the wheels which may later occur during, or after, a test disconnection.

Abstract: A rear-axle transmission arrangement supports the transmission of at all fastening points and forms at least its output-side fastening points and forms by support bearings fixed to the body independently of the rear-axle support to improve driving comfort and handling performance. This arrangement permits vibrations resulting from the drive torque and a rising-up of rear-axle transmission and rear-axle support to be controlled better or be avoided. In addition, forces induced by the drive torque cannot bring about any shifts in the rear-axle support causing steering movements.

Abstract: A pull-to device pulls a vehicle closing component into a locked end position automatically in a final closing-movement phase. Whereas prior pull-to devices formed by a closure or even by a plurality of closures were effective only after the closing component has reached a pre-engagement position on the counter-component, here, during the closing movement, this pre-engagement position is assumed large independently of the closing accuracy of the closing component. For assistance, there is an additional pull-to device which consists of a leading catch coupling.

Abstract: A cartridge case comprises a metal base piece, a plastic sleeve casing, and a plastic tubular section made as a separate part extending along the inside surface of the sleeve casing. The tubular section includes a flange which extends along and is in intimate contact with an inner face of the base piece. A snap lock design locks the sleeve casing, the base piece and the tubular section together. When the cartridge case includes a flash tube fitted onto the base piece, the tubular section also includes a lip extending from the flange and in intimate contact with the outer surface of the flash tube.

Abstract: In a process for adaptive control of an internal-combustion engine or of another drive component of a motor vehicle, a set value/actual value comparison of a critical time interval with regard to an optimum operating behaviour is triggered upon each non-steady operating state. Set values and correction values for influencing a casual controlled variable with regard to the operating behaviour are assigned to selected operating points of the internal-combustion engine in the form of stored characteristic maps. If appropriate, the correction values are replaced by new correction values, determined according to a deviation. If the non-steady operating state occurs at a non-selected operating point, intermediate values for set value and correction value are interpolated.

Abstract: An apparatus for cross-cutting a treetrunk comprises gripping members which embrace the treetrunk, a feeding mechanism for moving the treetrunk in its longitudinal direction, and a saw which moves transversely to the longitudinal direction and cuts the treetrunk into predetermined lengths. One of the gripping members includes a rotatable guide roller having peripherally spaced apart teeth which engage the treetrunk. The apparatus also comprises a displacement pickup unit which ensures that the treetrunk is cut to a predetermined length. The displacement pickup unit is connected to the guide roller and detects the number of rotations of the guide roller, thereby detecting the longitudinal displacement of the treetrunk. The displacement pickup unit is located within the gripping member so that it is shielded from outside influences.

Abstract: The flywheel elements are resiliently coupled by means of two groups of springs which are connected in parallel. One group of springs operates with play and becomes operative substantially only when high torques are transmitted. At low speeds when only low torques can be generated by the engine, the flywheel has a very low resonance frequency determined solely by the second group of springs without play. This frequency remains below the frequencies of the vibrations which occur in this service phase. Upon the transmission of higher torques generated by the engine at higher speeds, although the resonance frequency rises due to the effect of the first group of springs with play, nevertheless, the resonance frequency remains below the frequency of the vibrations which occur at higher speed.

Abstract: A motor vehicle bumper has a crossmember fixed to the body and an impact-confronting collision part. Non-regenerable deformation members are arranged between the collision part and the crossmember, at least in the region of support points, and the impact-confronting collision part is secured to the crossmember via fastening bolts passing through the deformation members. During a deformation of the non-regenerable deformation members, the collision part is displaceable in the longitudinal direction of the vehicle in order to increase the deformation capacity, while preserving the indicator effect of the support points. The collision part is designed as a trim part encasing, at least in the region of the support points, a core consisting of elastically deformable foam. With the exception of the region of the support points, the bumper has a gap on the energy-absorber side.

Abstract: A head restraint for rear seats of convertibles is attached to a U-shaped roll-over bar and can be displaced with the roll-over bar. The roll-over bar can be raised from a lowered position into a support position and spans to a large extent the width of the interior of the vehicle. The lateral legs of the roll-over bar are equally curved along a rear wall of the rear seat rest with a center of curvature on the seat side of the rear seat rest.

Abstract: A device is described for electrically pre-heating the intake air or the intake mixture of an internal combustion engine having at least on intake pipe. So that low-loss pre-heating, without considerable impairment of flow in the intake pipe, can also be realized in such zones in which the intake pipe has a geometrically irregular shape. It is proposed to perform the pre-heating via a layer of high electrical resistance applied to the inner surface of the intake pipe.
