Sliding cage of universal joint for vehicle

Abstract

The present invention relates to a sliding cage of universal joint for vehicle, and more particularly, to a sliding cage of universal joint for vehicle for making a shaft joint and a pipe joint smoothly slide as well as operating an elastically contacted needle bearing, installed to the sliding cage, when a universal joint is slipped or delivers rotating torque. The present invention provides a sliding cage of universal joint for vehicle, comprising: a sleeve; a plurality of mountings positioned to keep distance along the longitudinal direction of the outer side of the sleeve; and a needle bearing and a ball bearing which are installed to the mountings, wherein the sliding cage is provided to the universal joint constructing a steering apparatus for vehicle, thereby being assembled to deliver torque while being slipped toward axial direction.

Description

technical field [0001] The present invention relates to a sliding cover of a universal joint for automobiles, and more particularly, relates to a structure so that when the universal joint performs a sliding operation or transmits a rotational torque, a needle roller bearing mounted on the sliding cover can elastically contact and operate, while the shaft Sliding covers for universal joints for automobiles that allow joints and pipe joints to slide and move smoothly. Background technique [0002] Generally, an automobile is provided with a steering device for a driver to switch the forward direction of the vehicle. The steering device includes: a steering wheel arranged in front of the driver's seat so that the driver can turn it, and a steering column arranged below the steering wheel, which converts the rotational motion of the steering column into linear motion while increasing the steering force to change A gearbox for the direction of the tire, a universal joint for tr...

Problems solved by technology

[0010] However, in the structure of the needle roller bearing, when the shaft joint slides along the inside of the pipe joint, or when the universal joint rotates due to the operation of the steering wheel, the entire outer surface of the needle bearing is in contact with the inner surface of the pipe joint. surface contact, so has the problem of increased coefficient of friction

[0011] For this reason, the sliding operation and the rotating operation of the universal joint cannot be performed smoothly, so the steering feeling of the steering device cannot be maintained well.

[0012] In addition, as the steering gear is used over time, the needle bearings are worn due to frictional resistance and torque transmission, so when the steering gear is used, the rotation direction interval of the steering wheel is correspondingly increased, which not only produces noise, but also reduces the steering force. performance
