摘要: A metal sleeve including a metal body which surrounds an inner channel running between a proximal and a distal opening. The inner channel has at least one groove set back into the metal body, running in the longitudinal direction of the inner channel and stepped on both sides by a distal and a proximal front edge. The proximal front edge of the groove is produced by impact extrusion.

摘要: A gearbox assembly for power take off from an electric motor of an electric power assisted steering apparatus comprising a gearbox housing which houses a worm shaft and a gear wheel, is disclosed. The worm shaft incorporates one or more external helical worm teeth. A main bearing assembly supports the worm shaft at an end closest to the motor. A tail bearing assembly supports the worm shaft at an end furthest from the motor, in which at least the tail bearing assembly is free to move relative to the housing through a limited range of motion that enables the worm shaft to move radially away from the axis of the wheel gear. The gearbox assembly further comprises a flexible coupler which connects the worm shaft at the main bearing end to a power take off from the motor so as to transfer torque from the motor to the worm shaft. The flexible coupler comprises a first hub part providing a connection to the worm shaft, a second hub part providing a connection to the power take off from the motor, and a flexible membrane that connects the first hub part to the second hub part. The flexible membrane provides a primary path for the transfer of torque from the first hub part to the second hub part.

摘要: A gearbox assembly for power take off from an electric motor of an electric power assisted steering apparatus comprises a gearbox housing which houses a worm shaft and a gear wheel. The worm shaft incorporates one or more external helical worm teeth. A main bearing assembly supports the worm shaft at an end closest to the motor. A tail bearing assembly supports the worm shaft at an end furthest from the motor. At least the tail bearing assembly is free to move relative to the housing through a limited range of motion that enables the worm shaft to move radially away from an axis of the wheel gear. A piston is slidingly received within a bore in an end of the wormshaft and has a has a head at an end facing the motor which connects with an output shaft of the motor. An interface between the recess of the piston and the protrusion of motor shaft defines a pivot axis of the worm shaft. A spring located within the bore in the end of the worm shaft and is compressed between the worm shaft. The piston has a tapered shoulder located within the bore that increases in diameter from an end furthest from the motor towards an end nearest the motor. The gearbox assembly further includes an annular o-ring that sits on the tapered shoulder, the spring acting on the piston through the o-ring whereby movement of the wormshaft towards the motor shaft compresses the spring which in turn drives the o-ring along the tapered shoulder until the o-ring becomes wedged between the piston and the inner wall of the bore of the wormshaft.

摘要: A drive device for a motor vehicle includes a drive unit with a driveshaft, a housing, and a planetary gear set disposed in the housing with a sun gear. A connection device allows relative movements, running in an axial direction of the driveshaft, between the sun gear and the driveshaft, via which the sun gear is drivable by the driveshaft. An axial bearing has a roller bearing for axially mounting the sun gear where the axial bearing is disposed in the axial direction between the drive unit and the planetary gear set. A bearing casing formed separately from the housing supports the roller bearing in the axial direction via an outer ring of the roller bearing non-rotationally connected to the bearing casing and the bearing casing is connected axially fixedly to the housing.

摘要: The present disclosure relates to a cycloidal reducer. The cycloidal reducer according to the present disclosure includes a reduction unit configured to reduce a torque input and an output unit configured to transfer the reduced output to the outside. A cycloidal rotor that is one constituent element of the reduction unit has a tooth-type protrusion formed in the shape of a circular arc. Thus, the level of difficulty of process is decreased more than when the tooth-type protrusion in the related art is formed in the shape of a broken line. Accordingly, the advantage of increasing the productivity is provided. In addition, rotor pins are accommodated in through-holes, respectively, that are equally spaced in the cycloidal rotor. A busing is formed that fills a gap between the through-hole and the rotor pin is formed in order for the rotor pin to stably transfer rotational power. Accordingly, the advantage of effectively distributing a load and stably transferring a reduction torque to the outside is provided.
