Problems solved by technology

[0004] The dust cover structure of the existing automobile steering transmission shaft has the defects of poor sealing effect and short service life: specifically, during the steering process of the automobile, the steering transmission shaft 3 is radially displaced, resulting in the seal lip 6a Due to the clearance fit between the nylon bush 7 and the steering drive shaft 3, when the rubber bush 6 at the seal lip 6a wears and fails, it will directly lead to dustproof failure, water leakage, poor sound insulation, and steering Abnormal sound and other problems

Abstract

The invention provides a dust cover structure of an automobile steering transmission shaft, which comprises a universal ball assembly, the universal ball assembly comprises a universal ball, an upper ball cover and a lower ball seat, the upper ball cover and the lower ball seat are buckled on the upper part and the lower part of the universal ball, the universal ball is provided with a through hole for the automobile steering transmission shaft to pass through, and the through hole is in interference fit with the automobile steering transmission shaft; the telescopic cover body is used for covering a through hole in the connecting position of the automobile steering transmission shaft and the automobile body, the first end of the telescopic cover body is fixedly connected to the lower ball seat of the universal ball assembly in a sleeved mode, and the second end of the telescopic cover body is fixed to the corresponding automobile body. The sealing device has the advantages of being good in sealing effect, long in service life and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a dustproof cover structure for an automobile steering transmission shaft. Background technique [0002] In the current automotive steering system design, the steering gear is located in the engine compartment, and the steering column is located in the cockpit. The perforated connection of the front wall is designed with a dust cover structure. It is well known that the unreasonable design of the steering dust cover structure will lead to the failure of the dust protection, and the engine noise will be transmitted to the cockpit through the perforation, which will affect the driving comfort. [0003] Such as figure 1 It shows the structure of the dust cover of the existing automobile steering transmission shaft, including rubber sleeves 6 and metal pressure plates 8 which are overlapped in sequence. A nylon bushing 7 is arranged between the rubber sleeve 6 and the stee...
