Embodiment Construction

[0026] figure 1 , 2 The shown constant velocity universal joint 1 mainly includes:

[0027] - A male member or tripod 2 with a hub 4 of central axis X-X, from which project three radial arms 6 angularly spaced by 120°. Each arm 6 has its own axis Y-Y. The end of each arm 6 forms a spherical bearing 8 integral therewith and centered on the axis Y-Y of the respective arm 6 . The male member 2 is connected to a first shaft 10 of axis X-X.

[0028] - A female member or socket 12, the central axis C-C of which coincides with the axis X-X in the alignment of the universal joint 1 shown. On either side of each arm 6 , the socket 12 has two opposing rolling tracks 14 . The socket 12 is connected to a second shaft 16 with a keyway 18 .

[0029] - For each arm 6 there is a rolling assembly 20 with axis Z-Z, at figure 1 In the straight-line position of the gimbal shown, this axis Z-Z coincides with the axis Y-Y of the corresponding arm 6 .

[0030] Each rolling assembly 20 includ...

Abstract

The invention relates to a homokinetic joint (1) that comprises a male member (2) with several arms (6), a female member (12) for receiving the male member (2), a roller (24) mounted and freely rotating on each arm (6), a spring (31) provided between the male member (2) and the female member (12) and for urging the male member (2) away from the female member (12), and a cup (34) provided between the spring (31) and the male member (3). The cup (34) includes a skirt (44) comprising an outer surface (46) designed to contact at least one of said rollers (24) when the joint is in the separated state. Application in homokinetic joints for automotive vehicles.

Description

technical field [0001] The invention relates to a constant velocity universal joint, which has: [0002] - a male member with a plurality of arms; [0003] - a female member receiving the male member; [0004] - rollers freely rotatable mounted on each arm; [0005] - a spring interposed between the male member and the female member and adapted to push the male member away from the female member; [0006] - a cup holder placed between the spring and the male member. Background technique [0007] A prior art constant velocity joint includes a male member having a plurality of arms and a female member receiving the male member. A roller is freely rotatable and swingably mounted on each arm of the male member. [0008] In known constant velocity joints, a spring is placed between the male and female members, the spring being adapted to push the male member away from the female member on the one hand and push the female member against it on the other hand a stop. [0009]...
