Abstract: A self-pumping hydropneumatic shock absorbing strut with internal level regulation contains a work cylinder which is filled with damping medium and is under the pressure of gas cushions, and a piston which can be displaced in the work cylinder on the end of a piston rod having a cavity disposed therein. The cavity in the piston rod acts as a pump cylinder of a pump rod which is fastened to the work cylinder, and, as a result of the spring movements, damping medium can be transported from a low pressure chamber into a high pressure chamber. The pump rod is realized in two parts, including an inner part which is connected to the work cylinder and an outer part which coaxially surrounds the inner part at least partly with radial clearance, which outer part is non-detachably connected to the inner part on the end of the outer part farther from the work cylinder.

Abstract: Self-pumping hydropneumatic shock absorbing strut with internal level regulation, with a work cylinder which is filled with oil and is under the pressure of gas cushions, and with a damping piston which can be displaced in this work cylinder. The damping piston slides on the end of a hollow piston rod, the cavity in the piston rod acts as a pump cylinder of a pump rod which is fastened to the work cylinder. Whereby, when the piston rod is extended, damping medium is sucked out of a reserve chamber by way of a suction valve, and when the piston rod is inserted, damping medium is transported into the work chamber by way of a non-return valve and a ring-shaped gap which is formed between a control sleeve and the hollow piston rod. Whereby the pump rod is fastened so that it can move axially, radially and/or with free angular movement in the end wall of the work cylinder.

Abstract: A process for producing a frictionally locking connection of two structural component parts, especially a shaft and a hub, including plastically deforming a round structural component part into an oval or polygonal shape by applying force, applying additional force to substantially elastically round the oval or polygonal structural component part, assembling the structural component parts while maintaining the additional force, and then cancelling the additional force so that the round structural component part springs back into the oval or polygonal shape whereby the structural component parts are connected with one another by a press fit.

Abstract: An electrically powered vehicle including an electric motor connected to drive a wheel of the vehicle. The electric motor receives a supply of electric current from a power source; a power electronics device and superordinated controller regulate the current supply based upon signals received from a driver or operator of the vehicle. A sensor for sensing data indicative of an accident or impending accident is connected to the superordinated controller in which the sensed data is compared to predetermined limit values to determine if an accident situation exists. Upon determining that an accident situation exists, the superordinated controller activates a circuit breaker to disconnect the electric power supply and thereby interrupt the supply of electric current to the electric motor.

Abstract: A clutch actuator for a motor vehicle friction clutch has a drive, a gear unit which converts the movement of the drive into a substantially translatory movement of an output member, the excursion of this gear unit being definable with respect to every working direction by at least one stop, and a clutch position detector. A damping device is associated with each stop. In a position of the gear unit in which the gear unit, in a movement directed toward the stop, has reached an exactly defined reference position relative to this stop, this reference position being situated prior to the stop, the damping device can be activated in order to retard the gear unit until the latter comes into contact with the stop.

Abstract: An idler wheel hub with freewheel mechanism, which encompasses an inner freewheel ring and an outer freewheel ring. Located radially between the freewheel rings are an inner cage and an outer cage. These cages are provided with recesses so that clamping bodies can penetrate therein. The clamping bodies are directionally prestressed so as to be in contact with the freewheel rings. The axial extension of the components is limited by side plates, which are located between the freewheel rings, and the freewheel rings are in turn centered by the side plates. One of the side plates forms a single part with the outer cage of the freewheel mechanism. The second side plate locks securely into the outer cage of the freewheel mechanism. The plates are provided with axially outwardly arranged glide devices. At least one of the side plates is attached in a turn-proof manner relative to the outer freewheel ring.

Abstract: A hydrokinetic torque converter with a housing (23, 26) connected to an internal combustion engine; a turbine (21); and a bridge coupling or lock-up clutch (45) which has a plurality of friction linings (1, 7; 31, 39, 40; 54, 57) that can be brought in a predeterminable order and independent of one another into active connection with a particular associated friction surface for establishing a frictional connection between the housing (26) and the turbine wheel (21). Under pressure the converter bridge coupling acts initially as a single-surface and later as a double-surface converter coupling. In addition, the bridge coupling can have a low transmission capacity per pressure unit in the low pressure range and the transmission capacity can be increased disproportionately starting at a certain pressure range.

Abstract: A lock-up clutch for a hydrodynamic torque converter which includes at least one piston which can be displaced in the axial direction and can be connected to the converter housing by means of at least one friction zone, which piston defines, by means of the side which faces the converter housing, a chamber in which, when the lock-up clutch is active, the pressure is lower than the pressure in the converter circuit, and which, in the vicinity of a friction zone, has at least one channel for the flow of hydraulic fluid from the converter circuit. The quantitative flow of hydraulic fluid is a function of the pressure exerted by the converter. The lock-up clutch further includes at least one friction zone which has at least one friction lining, whereby the lock-up clutch has a total of at least two friction linings of different axial dimensions which, in the event of different pressures acting in the converter, come into at least partial effective connection with the matching friction surfaces.

Abstract: A twist-grip shifter for bicycles having a twist grip or grip part which is actuated by the rider's hand to change the gears of the bicycle, and a cable winding mechanism or coil wind-up mechanism. The twist grip and the cable winding mechanism of the twist-grip shifter are connected to one another, and debris and other contaminants can be prevented from entering the interior of the twist-grip shifter near this connection by providing a contactless seal or a friction seal. The contactless seal includes a projecting collar on the cable winding mechanism which extends into a groove formed in the twist grip. The collar of the cable winding mechanism essentially does not contact the groove of the twist grip. The friction seal includes a lip or flange formed from the rubber material of the twist grip, which lip then contacts a portion of the collar of the cable winding mechanism.

Abstract: The present invention generally relates to the attachment of a centrifugal mass or a modular clutch to the output end of a crankshaft of an internal combustion engine. For this purpose, axially-oriented gear teeth can be introduced in both parts, e.g. a serration, and there can be a central screw element which can extend into a threaded portion in the crankshaft. The present invention teaches that an axially-oriented spring bias can be applied to both parts to create a reliable connection between the parts of the gear teeth.
