A ball cage type sliding universal joint

Abstract

The invention provides a gate type sliding universal joint. The gate type sliding universal joint comprises an outer star wheel, an inner star wheel, a gate and a plurality of steel balls, wherein the outer star wheel is arranged at the outer side of the gate, the inner star wheel is arranged at the inner side of the gate, the multiple steel balls penetrate through the gate, are evenly distributed along the periphery of the gate and are matched with a ball way of the outer star wheel and a ball way of the inner star wheel respectively, each steel ball is shaped like a spherical frustum, the distances from the spherical center of each steel ball to the two end surfaces of the corresponding steel ball are equal, and the two end surfaces of each steel ball are arranged in the ball way of the outer star wheel and the ball way of the inner star wheel respectively. The bottom of the cross section of the ball way of the outer star wheel is a straight line, the two sides of the cross section of the ball way of the outer star wheel are arc lines attached to the spherical surfaces of the steel balls, the bottom of the of the cross section of the ball way of the inner star wheel is a straight line, the two sides of the cross section of the ball way of the inner star wheel are arc lines attached to the spherical surfaces of the steel balls, and intervals exist between the two end surfaces of each steel ball and the bottom of the ball way of the outer star wheel and between the two end surfaces of each steel ball and the bottom of the ball way of the inner star wheel respectively. Compared with a gate type sliding universal joint in the prior art, the gate type sliding universal joint is small in size, light in weight, small in occupied space and favorable for light weight modification of medium and high end cars, reduces energy consumption of medium and high end cars, and improves work efficiency.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a cage type sliding universal joint. Background technique [0002] The high-performance constant velocity universal drive shaft assembly for mid-to-high-end cars includes fixed-end constant velocity universal joints, sliding end constant velocity universal joints, and constant velocity universal joints connected to fixed end constant velocity universal joints and sliding end constant velocity universal joints. between drive shafts. In addition to high-speed and stable transmission of power, the high-performance constant velocity universal drive shaft assembly also needs to reduce the weight of the assembly, reduce the space size, improve work efficiency and reduce energy consumption. [0003] At present, the constant velocity universal joint at the sliding end of the high-performance constant velocity universal drive shaft assembly of mid-to-high-end cars adopts a spherical c...

AI Technical Summary

Problems solved by technology

The cage-type sliding universal joint with such a structure is bulky and occupies a large space, which is not conducive to installation and requires a large installation space. Because of its large size and heavy weight, it is not conducive to the assembly of high-performance constant velocity universal joint transmission shafts for mid-to-high-end cars. The resulting lightweight results in high energy consumption and low work efficiency for mid-to-high-end cars
