Abstract
The invention relates to a steering shaft dustproof cover of an automobile steering system, comprising an upper cover and a lower cover; the middle of the upper cover and the lower cover is provided with a hole sleeved with a steering shaft sleeve; wherein, the upper cover is a rubber part and the lower cover is made of hard plastic; the lower part of the upper cover is provided with a connecting neck ring inserted into the lower cover; the upper edge of the connecting neck is uniformly provided with at least two buckles; correspondingly, at least two humps are arranged on the upper edge of the lower cover; furthermore, the upper cover is internally embedded with a vibration reduction soft pad ring which can further prevent the vibration and more effectively prevent the noise in a starting cabinet from entering the cab. The steering dustproof cover can ensure right position and convenient installation when the steering shaft dustproof cover and the steering device shell are installed; furthermore, the invention has good dustproof and sound insulation effect without the phenomena of position transformation and dropping, etc. in application process.
Description
Technical field
The present invention relates to steering axles, be specifically related to the installation relation of steering shaft and body platform.
Background technique
Present automobile is arranged in engine compartment with general employing of steering system with commutator (steering box), and pass the form that the steering wheel in engine compartment and the cockpit connects mutually by steering drive axle (being steering column), for NVH performance demands in outward appearance and the cockpit, the steering shaft dust-proof cover generally need be set at the position that steering shaft passed the body platform hole to be blocked steering column and passes engine compartment and cockpit and remaining slit, prevented that the dust kicked up at the bottom of the car and muddy water etc. from entering in the cockpit, stoped the noise that starts in the cabin to import in the cockpit simultaneously.
It is to be made of loam cake and lower cover two-part that existing steering shaft dust-proof cover adopted more, all adopts rigid plastics, and loam cake and lower cover are by the staggered mutual clamping of latch.In use there is following defective in this structure: the one, and loam cake and lower cover adopt the form of staggered latch clamping, contraposition difficulty during clamping, dislocation easily; The 2nd, all adopt rigid plastics, mutually clamping lacks flexibility, and comes off easily, and owing to lack flexibility, and cover body and front floor of vehicle body plate hole are easy to generate displacement for to contact firmly, can not reach good sealing.
Summary of the invention
The objective of the invention is to deficiency, propose a kind of steering shaft dust-proof cover of automobile steering system, install, guarantee sealing with convenient at the prior art existence.
Technological scheme of the present invention is as follows:
A kind of vehicle steering shaft dust protector, comprise loam cake and lower cover, hole with the steering shaft suit is arranged in the middle of loam cake and the lower cover, wherein loam cake is a rubber parts, lower cover adopts rigid plastics, the loam cake bottom is to have a circle to insert the interior connection neck of lower cover, evenly is provided with at least two buckles at the top edge that connects neck, is provided with two projectioies accordingly at least in the lower cover upper edge.
In loam cake, also be embedded with a circle vibration damping cushion in addition, can further prevent vibration effectively, also more effectively stoped the noise that starts in the cabin to import in the cockpit simultaneously.
The dust-proof cover loam cake that this structure adopts is a rubber structure, can prevent effectively that the dust kicked up at the bottom of the car and muddy water etc. from entering in the cockpit, the vibration damping cushion that loam cake inside is set up can more effectively prevent vibration, this inside and outside two-part combine, and can stop the noise that starts in the cabin to import in the cockpit effectively.The lower cover of dust-proof cover adopts rigid plastics, closely cooperate in when assembling and steering gear housing, this has just guaranteed at when assembling dust-proof cover and the correctness of the preceding floor of operator cabin cooperation position, the direct clamping of rubber buckle that covers on the plastics of dust-proof cover lower cover projection and the steering shaft dust-proof cover simultaneously, clamping is convenient, contraposition is easy, make dust-proof cover in use be difficult for producing situations such as being shifted, coming off, dustproof good with soundproof effect.
