A joint for the angularly adjustable drive-connection of a cylinder block and a driveshaft of a hydrostatic bent axis piston unit. The joint has a shank which is rotatable about its longitudinal axis defining a joint axis, on both ends of the shank roller carriers project radially and basically perpendicular to the joint axis. On each roller carrier a roller is provided rotatable around a roller axis. The rollers are secured in axial direction against slipping-off of the roller carriers by means of an embossed area located axially outside of the roller on the respective distal end portion of the roller carrier.

A constant velocity universal joint has a large-diameter mounting portion fastened and fixed by a first fastening clamp onto a boot receiving portion of an outer joint member, and a small-diameter mounting portion fastened and fixed by a second fastening clamp onto a boot receiving portion of a shaft. A circumferential clamp groove to which the first fastening clamp is fitted is formed in an outer peripheral surface of the large-diameter mounting portion. A protruding portion is formed at a boot outer side end portion of an inner peripheral surface of the large-diameter mounting portion. A recessed portion to which the protruding portion is fitted is formed in the boot receiving portion being a cylindrical surface of the outer joint member. A projection is formed in the vicinity of a boot inner side of the recessed portion.

A wheel support device for a vehicle includes a bearing that rotatably supports a wheel, and is lubricated by a lubricant, a bearing support member, and a self-discharge type charge eliminator provided on a surface of a particular member. The self-discharge type charge eliminator is configured to change air around the self-discharge type charge eliminator into negative air ions, and eliminate charge by causing the air ions to attract positive charges of the particular member for neutralization, so as to reduce the quantity of charge of the particular member, and thereby reduce the quantity of charge of the lubricant.

A constant velocity joint assembly (20) includes an outer race (22) having a plurality of outer tracks (42) formed in an inner surface thereof and an inner race having a plurality of inner tracks (54) formed in an outer surface thereof. A cage (26) is disposed between the inner race and the outer race. A plurality of torque transferring elements (28) are disposed in the cage. Each torque transferring element contacts one of the outer tracks of the plurality of outer tracks and one of the inner tracks of the plurality of inner tracks. A drive sleeve (30) is separated from the plurality of torque transferring elements by the inner race. Also, the drive sleeve is in driving engagement with the inner race. A stopper portion (74) is attached to the drive sleeve. The stopper portion comprising a portion that reduces in thickness toward an outer end thereof.

A dielectric insulating insert assembly arranged to be positioned between a drive shaft and a driven shaft of a motorised drive assembly, the insert assembly comprising a plurality of elongate pins of dielectric material configured to engage, respectively, with the drive shaft and the driven shaft in torque transfer engagement, the pins providing a dielectric barrier between the drive shaft and the driven shaft.
