Problems solved by technology

However, due to the above-mentioned design constraints, simple sizing of the design parameters in conventionally constructed double-offset gimbals is not sufficient to achieve a compact design, which means sacrificing the blank area of ​​the contact length on the ball recess or the ellipse on the ball track. The length of the contact blank area to achieve a compact design, resulting in a reduction in the durability of the ball track or the durability of the ball recess of the cage

Abstract

A constant velocity joint has an outer joint part (38), an inner joint part (44), a ball cage (52) and a plurality of balls (50) located in the cage (52). The outer surface of the inner joint part (44) is provided with two radii (R21 R22) and the inner surface of the ball cage (52) is provided with two radii resulting in a joint that is more compact, more durable and lubricated better than known joints.

Description

technical field [0001] The present invention relates to vehicle joints, such as constant velocity joints of the cage type. Background technique [0002] As shown in FIGS. 1A and 1B , a conventional double offset joint 10 includes an outer joint portion 12 , an inner joint portion 14 , a cage 16 and at least one ball 18 . Typically, a plurality of spheres 18 are provided. The outer gimbal part 10 has a cylindrical shape formed with a plurality of circumferentially spaced linear guide tracks 20 having a Gothic arc or ellipse form. The inner gimbal portion 14 has circumferentially spaced apart linear guide tracks 22 formed on an outer spherical surface 24 . Cage 16 retains a plurality of balls 18 in a plurality of recesses 26 spaced circumferentially about cage 16 . Cage 16 has an inner concave spherical surface at R2 and an outer convex spherical surface at R1. R1 and R2 are offset from the center of the ball recess by e in the axial direction to opposite sides of point O ...
