[0004] To achieve the above object, the utility model provides the following technical scheme:

[0005] A kind of steering gear rubber bushing, including outer protective sleeve, the inside of the outer protective sleeve is fixed with inner layer sleeve, the upper and lower ends of the outer protective sleeve are integrally formed with flange, the surface of the flange far from the outer protective sleeve is fixed with dustproof pipe, the dustproof pipe is set as bellows.

[0006] As a further scheme of the utility model: the dustproof pipe is integrally formed with abutting ring at one end far from the flange, the surface of the abutting ring far from the dustproof pipe is set as plane.

[0007] As a further scheme of the utility model: support block is fixedly connected to the inner wall of the dustproof pipe.

[0008] As a further scheme of the utility model: the end of the inner layer sleeve protrudes from the surface of the flange, the surface of the flange is provided with recess, the recess is annular, and the recess is attached to the outer surface of the inner layer sleeve.

[0009] As a further scheme of the utility model: the end surface of the inner layer sleeve is set as rough surface.

[0010] As a further scheme of the utility model: the end surface of the inner layer sleeve is provided with horizontal lines.

[0011] Compared with the prior art, the utility model discloses the beneficial effects are:

[0012] Through setting the dustproof pipe of the corrugated surface on the baffle surface, make the dustproof pipe have certain elasticity, when the bushing is installed to the surface of the steering gear, through the abutment ring abutting on the component surface of the two sides of the steering gear, and the push of the dustproof pipe that the support block combines, can make the abutment ring always abut on the component surface, thereby play the effect of sealing, effectively avoid the sewage and other dirt in the air from the gap into the steering gear and the bushing between, play the role of protection to the steering gear.

[0017] Please refer to Figs. 1-3 In the first embodiment of the utility model, a kind of steering gear rubber bushing, including outer protective sleeve 1, the inside of outer protective sleeve 1 is fixed with inner sleeve 3, the upper and lower end of outer protective sleeve 1 is integrally formed with baffle 2, the surface of the side of baffle 2 away from outer protective sleeve 1 is fixed with dustproof pipe 5, and dustproof pipe 5 is set as corrugated pipe.

[0018] Preferably, the end of dustproof pipe 5 away from baffle 2 is integrally formed with abutment ring 7, and the side surface of abutment ring 7 away from dustproof pipe 5 is set as plane.

[0019] Preferably, the inner wall of dustproof pipe 5 is fixedly connected with support block 6.

[0020] Preferably, in a kind of steering gear rubber bushing, the end of inner sleeve 3 protrudes from the surface of baffle 2, the surface of baffle 2 is provided with recess 4, recess 4 is annular, and recess 4 is set on the outer surface of inner sleeve 3.

[0021] Preferably, the end surface of inner sleeve 3 is set as rough surface.

[0022] In another embodiment, different from the first embodiment is that the end surface of inner sleeve 3 is provided with horizontal lines, and the same as the first embodiment.

[0023] The working principle of the utility model is: when using the rubber bushing, it is installed on the steering gear, the recess 4 is used to butt joint the installation of the steering gear, and the end surface of the inner sleeve 3 is provided with a rough layer or cross grain, which can play a certain degree of anti-skid effect, and because the surface of the baffle 2 is provided with the dustproof pipe 5, the dustproof pipe 5 is provided with corrugated pipe shape, has certain elastic deformation, and is easy to restore the original state, after installing the bushing, the abutting ring 7 is abutted on the surface of the components on both sides of the steering gear, and the supporting block 6 exists, always generates the thrust to the dustproof pipe 5, so that the abutting ring 7 can continuously abut on the surface of the components, avoids the sewage and dirt in the air from entering between the steering gear and the bushing through the gap, and plays a protective role on the steering gear.

[0024] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art in the technical range disclosed by the utility model, according to the technical scheme and the utility model concept of the utility model, is equivalent to replace or change, should be covered in the protection scope of the utility model.
