Embodiment

[0028] In this embodiment, refer to the attached figure 1 , the technical problem to be solved by the present invention is that in the existing technology, the existence of the ventilation groove will cause the grease leakage of the universal joint, and a new type of transmission shaft universal joint that prevents oil leakage is provided. The new type of transmission shaft that prevents oil leakage Shaft joints include:

[0029] A pressure relief device, a casing device, a transmission device, a shaft tube 1 and a spline shaft rod 13, the shaft tube 1 is fixedly connected to the casing device, and the pressure relief device and the transmission device are sequentially installed on the casing device Inside, the spline shaft 13 is fixedly connected with the housing device;

[0030] The pressure relief device includes: a first support cover 3, a second support cover 5 and a one-way pressure relief valve 2;

[0031] The shaft tube is fixedly connected to the housing device, the...

Abstract

The invention discloses a novel oil leakage prevention transmission shaft universal joint. The novel oil leakage prevention transmission shaft universal joint comprises a pressure relief device, a shell device, a transmission device, a shaft tube and a spline shaft lever, wherein the shaft tube is fixedly connected to the shell device; the pressure relief device and the transmission device are sequentially arranged in the shell device; the spline shaft lever is fixedly connected to the shell device; and by adopting the pressure relief device and eliminating a ventilating slot, the novel oil leakage prevention transmission shaft universal joint has the advantage that grease in the universal joint is prevented from leaking.

Description

technical field [0001] The invention relates to vehicle parts, in particular to a novel transmission shaft universal joint which prevents oil leakage. Background technique [0002] The propeller shaft is one of the main components of the automobile transmission system and is widely used in four-wheel drive vehicles. The transmission shaft is composed of universal joints, shaft tubes, built-in shock absorbers and balance weights and other sub-parts, among which the universal joint is the core component of the transmission shaft, which can guarantee the function of rotating in any direction of 360° and transmitting torque, depending on the internal structure , and divided into constant velocity and non-constant velocity universal joints. The constant velocity universal joint consists of sub-parts such as steel balls, cages, sheaths, sheath covers, inner star wheels, outer star wheels, and washers. [0003] During the operation of the whole vehicle, due to the design structur...
