Novel steering column dust shield

Abstract

The invention provides a novel steering column dust shield to solve the problems that the conventional automobile steering shaft shield has poor shielding effect and short service life, and relates to the field of automobile steering shaft shields. The novel steering column dust shield comprises a steering transmission shaft shield, a steering transmission shaft shield pressure plate and two steering shaft sealing rings arranged inside the steering transmission shaft shield, wherein corresponding mounting through holes are formed in the steering transmission shaft shield and the steering transmission shaft shield pressure plate; positioning columns are arranged on the steering transmission shaft shield; positioning holes are formed in the steering transmission shaft shield pressure plate. According to the invention, the novel steering column dust shield mainly prevents pollutants and muddy water from entering an automobile steering gear to cause the malfunction of a steering system, and adopts a separated structure; the assembly parts are rubber parts, have excellent elasticity and long service life; the muddy water and dust isolating effect is excellent and the steering transmission shaft is effectively kept away from pollution of outside pollutants in virtue of the two framework seal rings arranged inside the steering transmission shaft shield.

Description

Technical field: [0001] The invention relates to the field of automobile steering shaft protective covers, in particular to a novel steering column dust cover. Background technique: [0002] At present, most of the steering column dust covers on the market are plastic parts with poor elasticity and short service life. Since they are installed on the cowl of the steering column, holes need to be opened on the steering column dust cover to allow The intermediate shaft passes through the front wall. If the opening is too small, the intermediate shaft will rub against the steering column dust cover when it rotates, and damage the dust cover. If the opening is too large, the excessively large part will make the dust cover poor in sound insulation and easy to enter Dust, falling dust may affect the wear of the oil seal at the input shaft end of the steering gear, resulting in oil leakage and so on. Invention content: [0003] The object of the present invention is to provide a ...
