Abstract
The utility model discloses a waterproof dustproof steering gear of improvement type, its characterized in that: including steering gear main part, shell body, rack, screw lid and oil blanket, the screw lid is installed between steering gear shell body and rack, and the oil blanket is installed between screw lid and rack, being equipped with a recess on the rack, installing a waterproof shield on this recess, this waterproof shield is set up towards slope all around by connector an organic whole including connector and lid, this lid, and the interior inclined plane of this lid is to leaning on in shell body upper end department and extending to the shell body periphery. Adopt the straight inclined dustproof and waterproof lid of rubber material, on the one hand, slope setting makes water and dust drop subaerial more easily, on the other hand, and the elasticity that can improve the lid of rubber material, the noise reduction, the life of improvement product does not have the clearance between lid and the shell body, improve the waterproof dustproof function of product greatly.
Description
Technical field
The utility model relates to steering gear technical field, refers in particular to the steering gear of a kind of modified form water proof and dust proof.
Background technology
In automobile steering system, steering wheel assembly is contained in car body outside, in order to ensure that it can use for a long time, just must prevent that dust and water from entering assembly inside. In existing steering wheel dustproof and waterproof technology, be generally to seal by oil sealing sealing with at thread cap painting sealant. Due to the difference of vehicle service condition, may there is the part oil sealing can be aging, sealing is not enough, causes water and dust to enter, and the inner tooth bar of steering wheel assembly is got rusty, and while turning to, has some setbacks. In prior art, also there is the protective cover of use carry out water proof and dust proof, but also exist many defects in its design, such as having gap or easily colliding with, and what adopt is that metal material gets rusty easily etc. and to affect its dustproof and waterproof effect, also can affect the service life of steering gear.
Utility model content
In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provide the steering gear of a kind of modified form water proof and dust proof.
For achieving the above object, the utility model adopts following technical scheme: the steering gear of a kind of modified form water proof and dust proof, include diverter body, shell body, tooth bar, thread cap and oil sealing, thread cap is installed between steering gear shell body and tooth bar, oil sealing is installed between thread cap and tooth bar, described tooth bar is provided with a groove, one waterproof and dustproof cover is installed on this groove, this waterproof and dustproof cover includes connector and lid, this lid is obliquely installed towards surrounding by connector one, the interior inclined-plane of this lid is resisted against shell body upper end and extends to shell body periphery.
As a kind of preferred version, described waterproof and dustproof cover is rubber bodies.
As a kind of preferred version, the lid middle part of described waterproof and dustproof cover is corrugated body.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, by the design of preventing dust water cover, when steering gear work, preventing dust water cover rotates with ratch, dropping on water and the dust that dustproof and waterproof covers drops on the ground along outer wall, greatly reduce the possibility of dust and water approach axis machine assembly inside, particularly adopt the straight inclined preventing dust water cover of quality of rubber materials, on the one hand, be obliquely installed and more easily make water and dust drop on the ground, on the other hand, the elasticity that can improve lid of quality of rubber materials, reduce noise, improve the service life of product, very close to each other between lid and shell body, greatly improve the functions of waterproof and dustproof of product.

Detailed description of the invention
Please refer to shown in Fig. 1, it has demonstrated the concrete structure of the preferred embodiment of the utility model, the steering gear of a kind of modified form water proof and dust proof, include diverter body 00, shell body 10, tooth bar 20, thread cap 30 and oil sealing 40, thread cap 30 is installed between steering gear shell body 10 and tooth bar 20, oil sealing 40 is installed between thread cap 30 and tooth bar 20, this tooth bar 20 is provided with a groove 21, one waterproof and dustproof cover 50 is installed on this groove 21, this waterproof and dustproof cover 50 includes connector 51 and lid 52, this lid 52 is obliquely installed towards surrounding by connector 51 one, the interior inclined-plane of this lid 52 is resisted against shell body upper end and extends to shell body periphery, so between shell body and lid, there is no gap, effective anti-sealing and dust enter in steering gear, the setting of whole inclined-plane also can effectively and in time drain into ground by dust and water.
This waterproof and dustproof cover is rubber bodies, and the lid middle part of this waterproof and dustproof cover is corrugated body, and it can effectively improve the elasticity of waterproof and dustproof cover, reduces noise, improves service life.
Of the present utility model focusing on: by the design of preventing dust water cover, when steering gear work, preventing dust water cover rotates with ratch, dropping on water and the dust that dustproof and waterproof covers drops on the ground along outer wall, greatly reduce the possibility of dust and water approach axis machine assembly inside, particularly adopt the straight inclined preventing dust water cover of quality of rubber materials, on the one hand, be obliquely installed and more easily make water and dust drop on the ground, on the other hand, the elasticity that can improve lid of quality of rubber materials, reduce noise, improve the service life of product, very close to each other between lid and shell body, greatly improve the functions of waterproof and dustproof of product.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every foundation technical spirit of the present utility model, to any trickle amendment made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solutions of the utility model.
