Abstract: A clearance-free bearing bushing for universal joints which has a plurality of conical rollers located between a bearing bushing and a journal pin or the like. The rollers are pressed against their raceways by a spring element with a predetermined tension. On the side of the conical rollers facing away from the spring element, there is a thrust ring or the like, made of resilient material, which is free to move axially and which rests against the end surface of the conical rollers.

Abstract: A reset circuit is suggested for a microprocessor with which the microprocessor is reset, if the predetermined program ranges are left. During each cyclical input signal it is determined whether an output signal appears after a predetermined time. If this is not the case the reset process is performed. The reset process is also initiated if a predetermined output of the microprocessor remains in a defined position over an unduly long time.

Abstract: A control valve, in particular, an electrohydraulic control valve for controlling the injection pump of a diesel engine, incorporates a slider which is guided in a housing, in a manner permitting movement in the axial direction, the housing possessing radial flow-ports and, in the region of the inner peripheral surface, at least one annular space carrying a fluid. In order to ensure that the control-valve housing can be manufactured economically, the annular space is formed by a plurality of flow-ports which intersect in the region of the inner peripheral surface of the housing and pierce the housing radially.

Abstract: A bearing bushing is provided with a sealing ring having a conical bore surface on the side remote from the side at which a shaft is inserted. The rim of the bearing bushing is provided with a concial surface which cooperates with the conical surface of the sealing ring during insertion of the shaft so as to restrain the sealing ring in a manner that prevents it from being forced out of the bearing bushing. Alternatively, a restraining ring having a circumferential projection with a conical surface can be arranged to prevent unseating of the sealing ring when the shaft is inserted from the sealing ring side of the bearing bushing. A shaft being inserted exerts axial force on the sealing ring, causing the inner portion of the sealing ring to expand radially as the conical surface of the sealing ring slidingly ascends the conical surface of the bushing rim or restraining ring, thereby allowing easy insertion of the shaft.

Abstract: A sealing device for bearing bushings, especially for universal joints including a cup-shaped bearing bushing overlying a universal joint pin comprising an inner sealing ring, a sheet metal part connected to the bearing bushing adapted to fix the inner sealing ring in place in an axial direction, and an outer sealing ring provided on a shoulder of the joint pin supported in the bearing bushing, the inner sealing ring has a retaining part between the rolling elements and the free end of a preferably radially oriented shank of the sheet metal part, which has one or more openings, which connect the spaces defined by the outer sealing ring, the inner sealing ring, and the sheet metal part to each other.

Abstract: For a bearing bushing of generally cup-like form for universal joints including a universal joint pin, a check plate disposed between the axial end face of the pin and the bottom wall of the bushing, said check plate having on the side thereof confronting the pin concentric or circumferentially distributed projections with check surfaces and in that, proceeding from the end surface facing away from the pin, it has recesses or the like, which are arranged under the projections in the axial direction.

Abstract: A swivel pin bearing for rotatably seating a swivel pin in the yoke eye of a yoke arm. The bearing includes a bushing having a base portion and a sleeve portion integrally formed with the periphery of the base portion, this sleeve portion being arranged in the yoke eye with radial seating play, and a support plate releasably secured to the yoke arm. The base portion has a planar outer surface which opposes a planar inner surface of the support plate. An element is provided for coupling the bushing to the support plate such that axial displacement of the bushing relative to the support plate is prevented. The bushing is capable of sliding radial displacement relative to the support plate which is greater than the radial seating play of the bushing in the yoke eye.

Abstract: A pocket cage for a rolling bearing, e.g. a cylindrical roller bearing, made in a mold with single-piece, radially movable sliders, in particular out of plastic material with low deformability, which cage comprises two side rings connected by webs, with at least the circumferential outer surface or the bore being provided with projections which project into the pockets and extend along only part of the web length for retaining the rolling elements in the radial direction. In particular, a retaining projection is provided on a first side of each web and a recess, i.e. free space, is provided on a second side of each web. The angle between the oblique surface of the recess and the second side surface of the web is greater than or equal to the angle between the surface of the retaining projection which faces the rolling element and the first side surface of the web.

Abstract: A method and apparatus for checking sensors, in which the measurement signals, electrically detected in a checking unit and representative of the operating conditions of an internal combustion engine, are statically monitored. The measurement signals are checked with respect to whether their physical measured values are technically significant and lie within the permissible range and if an error is detected, a measure is initiated which counteracts this error; the cyclically detected measurement signals are thereby checked with respect to a change in their measured values from one sampling cycle to a successive one and are accepted only if the change in measured values is within permissible limits. Stochastic disturbances are gated out of the measurement signal and registered and tolerated up to a significant limit. If faulty measurement signals are detected, an emergency operating procedure is activated which counteracts this fault.
