Abstract
The invention provides a power steering oil return pipe which comprises a hose, a first U-shaped hard pipe body, a connection hose, a second U-shaped hard pipe body, a buffering hose and a steering gear connection connector. The steering gear connection connector is connected with the input end of the buffering hose, the output end of the buffering hose is connected with the input end of the second U-shaped hard pipe body, the output end of the second U-shaped hard pipe body is connected with the input end of the connection hose, the output end of the connection hose is connected with the input end of the first U-shaped hard pipe body, and the output end of the first U-shaped hard pipe body is connected with the input end of the hose. The power steering oil return pipe has the advantages that the hoses and the hard pipe bodies are arranged in a combined mode, on one hand, steering liquid flowing out of a steering gear is buffered by the buffering hose; on the other hand, the steering liquid is buffered through the first U-shaped hard pipe body and the second U-shaped hard pipe body, and damping of a hydraulic system is increased; the problem of abnormal sound, caused by road high-frequency impact, of a steering system can be effectively reduced.
Description
Technical field
The present invention relates to oil return pipe, particularly relate to a kind of power steering oil return pipe.
Background technology
The trend of traditional oil return pipe, by the restriction of arrangement space, generally adopts longer metal hard tube, due to the impact of road surface high frequency, it is easy to cause abnormal sound problem.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of power steering oil return pipe.
The invention provides a kind of power steering oil return pipe, including flexible pipe, first U-shaped hard tube, connect flexible pipe, second U-shaped hard tube, damping hose and connection steering gear joint, wherein, described connection steering gear joint is connected with the input of described damping hose, the outfan of described damping hose is connected with the input of described second U-shaped hard tube, the outfan of described second U-shaped hard tube connects with the described input being connected flexible pipe, the outfan of described connection flexible pipe is connected with the input of described first U-shaped hard tube, the described outfan of the first U-shaped hard tube is connected with the input of described flexible pipe.
As a further improvement on the present invention, the length of described damping hose is more than or equal to 300 millimeters.
As a further improvement on the present invention, the length of described damping hose is 400 millimeters.
As a further improvement on the present invention, the length of described damping hose is 500 millimeters.
The invention has the beneficial effects as follows: by such scheme, arranged by the combination of flexible pipe, hard tube, on the one hand, by damping hose cushion steering gear flow out turn to liquid；On the other hand, cushion and turn to liquid by the first U-shaped hard tube, the second U-shaped hard tube, and increase the damping of hydraulic system；Can effectively reduce the steering abnormal sound problem that road surface high-frequency percussion causes.
