摘要： The drive shaft (1) comprises end universal joints (5, 7) with accident-preventing end protections (19). Each accident-preventing end protection comprises a lubricant reservoir, delimited radially inwardly by a sleeve (63) of an inner fork (23) of the respective universal joint (5; 7) and radially outwardly by a rigid annular structure of the accident-preventing end protection.

摘要： The shaft coupling structure includes: a male joint, and a female shaft that is coupled to male joint. The outer peripheral surface of the male joint has an outer peripheral side concave-convex portion having a concave-convex shape in the circumferential direction and an annular concave groove, and the inner peripheral surface of the female shaft has an inner peripheral side concave-convex portion having a concave-convex shape in the circumferential direction. The outer peripheral side concave-convex portion and the inner peripheral side concave-convex portion engage with a concave-convex engagement. The outer peripheral surface of the male joint and an end portion on one side of the female shaft in the axial direction are welded and fixed together, and an embossed portion provided on the inner peripheral surface of the female shaft is arranged on the inner side of the annular concave groove.

摘要： A steering shaft for a motor vehicle includes a hollow shaft and an inner shaft which is arranged coaxially in the hollow shaft. The inner shaft is configured to be telescoped relative to the hollow shaft in the direction of the longitudinal axis of the steering shaft and is connected in a torque-transmitting manner to the hollow shaft via at least one rolling body. The rolling body is received in a rolling body cage such that it can roll in the direction of the longitudinal axis between the inner shaft and the hollow shaft. In order to achieve a high operational reliability with a relatively low manufacturing complexity, the rolling body cage has at least one seal element which bears sealingly against the hollow shaft and/or the inner shaft.

摘要： A plunging assembly of a driveshaft includes: an outer housing having a bore having a plurality of outer ball grooves extending in a longitudinal direction; an inner shaft being disposed to be able to undergo relative movement in the longitudinal direction in the bore of the outer housing and having a plurality of inner ball grooves that are paired respectively with the outer ball grooves to form a plurality of ball tracks; a plunging unit connecting the outer housing and the inner shaft to allow a plunging motion and a rotational power transmission between the outer housing and the inner shaft; and a stopper that is provided in the bore of the outer housing to limit relative movement of the inner housing and the inner shaft in a direction in which the inner shaft is inserted into the bore. The outer housing has a mounting hole communicating with the bore, and the stopper is a plug member that is inserted into the mounting hole in a state that a frontal end portion thereof is exposed to the bore.

摘要： A method may produce an axially movable connection between two components with a plastic as a sliding material arranged therebetween. The method may involve providing the two components and either at least one of the two components has a plastic coating or a plastic sleeve is provided between the components, joining the two components to form a unit via a pressing force in an axial direction, clamping the unit in a device in which the two components are clampable and subjectable to a displacement force in the axial direction, pressing a sonotrode against an outer of the two components and bracing the outer component against a counter-holder, injecting an ultrasound signal into the sonotrode and moving the two components back and forth in the axial direction until a displacement force or a displacement velocity reaches a target, and ending the ultrasound signal and removing the unit from the device.

摘要： A portion of the target guide plate interposed between the rolling surface of each ball and an inner surface of the sub-concave groove is supported at the other radial surface opposite to the rolling surface of each ball by the inner surface of the sub-concave groove at a state where one radial surface facing towards the rolling surface of each ball is pressed by the rolling surface of each ball and is thus curved along the rolling surface of each ball.

摘要： An intermediate steering shaft for a motor vehicle includes an outer hollow shaft, an inner hollow shaft that is arranged at least partially in the outer hollow shaft, and a profile shaft that is arranged in the outer hollow shaft and connects the outer hollow shaft and the inner hollow shaft to one another. The intermediate steering shaft also includes a plurality of guide arrangements that guide the profile shaft in the outer hollow shaft for displacing the profile shaft and the inner hollow shaft. An elastic element is arranged between a respective guide rail and a receiving section of the profile shaft. The elastic element is configured to provide play compensation for the respective guide arrangement and to transmit a torque that acts from the outer hollow shaft on the guide arrangement to the profile shaft.

摘要： A roller I-shaft includes an inner shaft, a hollow outer member, and a plurality of bearings. The inner shaft extends along an axis, and includes an outward face defining a plurality of first and second grooves that both extend axially and are alternately spaced circumferentially from one-another. The outer member is disposed radially outward from the inner shaft and includes an inward surface defining a plurality of first channels substantially aligned with the plurality of first grooves, and a plurality of second channels substantially aligned with the plurality of second grooves. The first grooves and the first channels form a plurality of first bearing races, and the second grooves and the second channels form a plurality of second bearing races. The plurality of bearings are disposed in a selected plurality of bearing races comprising one of the plurality of first bearing races and the plurality of second bearing races.

摘要： A rolling element intermediate shaft assembly includes a solid shaft having first and second ends. Also included is a tubular shaft configured to receive the first end, the tubular shaft having an inner wall with an axially extending groove formed therein, the axially extending groove having an inner surface. Further included is a wear plate having a bottom surface and an elastically deformable body having first and second ends, the body defining an axially extending channel, the body of the wear plate received in the tubular shaft groove. Yet further included is an outer surface of the body of the wear plate defining a gap between the wear plate and the axially extending groove of the tubular shaft, the gap reduced upon flexure of the wear plate. Also included is at least one ball bearing disposed within the wear plate channel between the wear plate and the solid shaft.
