摘要： A gear shifting drum (2) for the gear shifting device of a motor vehicle variable-speed gearbox has a curved path (11a to 11c) for guiding a catch (13) of the gearshift fork (12a to 12c) and the gearshift forks (12a to 12c) are directly linked to a synchronisation device. According to the invention, at least one wall (9, 10) which extends outwards in the radial direction is provided on the outer surface (8) of the gear shifting drum (2) for forming the curved path (11a to 11c).

摘要： Disclosed is an intermediate lever (1) for a variable valve drive of an internal combustion engine, comprising an impingement end and a pivoting end (2, 3), a cam stop area (4), and a support (5) for a return spring (6). The face of the impingement end (2) extends on the intermediate lever (1) and is provided with a sliding area (7) that comes in contact with a lever-type valve-opening device while the pivoting end (3) is designed so as to be able to communicate with eccentric means in order to modify the position of the intermediate lever (1). The cam stop area (4) is located between the impingement end and the pivoting end (2, 3). The inventive intermediate lever (1) is made of thin-walled sheet metal and is produced essentially in a stamping-bending process. The support (5) is located on a top face (8, 9) of the intermediate lever (1), in the edge region (10) towards the impingement end (2), while being provided with a convex extension which runs in the direction of the top face (8, 9) and comes in contact with a leg (11) of a torsion spring used as a return spring (6), and being laterally delimited by two guiding loops (12, 13).

摘要： The invention relates to a linear guide for transmitting torque between a tubular housing (2) that can be rotated about its longitudinal axis and a shaft (1) that is mounted in said housing so that it can be displaced axially by means of rolling bodies. Several axial anti-friction bearings (3) that surround the shaft (1), each having two bearing races or discs, with a set of rolling bodies therebetween, are arranged in the tubular housing (2) in the vicinity of a radial bearing plane. One bearing disc of the anti-friction bearings forms a bushing and is retained in the housing (2), the central axis of said bushing being offset in parallel by a certain distance (a) from the perpendicular of the longitudinal axis of the shaft and the other bearing disc of the anti-friction bearings (3) is dome-shaped, its convex dome surface being supported by a surface region of the shaft (1).

摘要： The invention relates to a radial antifriction bearing, which is comprised, in essence, of an outer bearing ring (2) and of an inner bearing ring (3) as well as of a multitude of roll bodies (4), which are arranged between the bearing rings (2, 3), are held at uniform distances from one another in the peripheral direction by a bearing cage (5) and which roll off with their bearing races (6) in two raceways (7, 8) that are incorporated in the inner side (9) of the outer bearing ring (2) and in the outer side (10) of the inner bearing ring (3). The roll bodies (4) are provided in the form of ball discs (11) that each have two parallelly arranged lateral surfaces (12, 13), which are symmetrically flattened from a spherical basic shape. In order to prevent edge stresses between the ball discs (11) and the raceways (7, 8) thereof, the invention provides that at least the raceway (8) in the inner bearing ring (3), on its outer edge areas (14, 15), and/or the bearing races (6) of the ball discs (11), at their edge portions (16, 17) adjacent to the lateral surfaces (12, 13), transition(s) into a logarithmically decreasing profile (Plog).
