Abstract

The utility model relates to an anti-shaking device for a silencing pipe in an automobile power steering high-pressure oil pipe, which comprises a metal steel sleeve and an inner lining, the inner lining is sheathed on the silencing pipe which is arranged between a high-pressure rubber pipe and the inner lining, and the metal steel sleeve molded by stamping and drawing a low-carbon cold plate is mounted in the position which is positioned on the outer side of the high-pressure rubber pipe and corresponds to the inner lining on the inner side. The anti-shaking device has the benefits of obviously controlling the stability of oil pressure in a power steering system, improving the situation of non-uniform direction-changing force for rotating a steering wheel, reducing the noise caused by an oil pump, also having a certain prevention role for preventing the inner wall of the rubber pipe from being worn due to long-term shaking of the silencing pipe, increasing the safety of the whole system and being conductive to solving the problems of unstable oil pressure and great noise caused by the shaking of the silencing pipe, even the leakage of the system caused by wear of the inner wall of the rubber pipe.

Description

A kind of anti-shake apparatus that is used for the inner hush tube of automotive power steering high-pressure oil pipe
Technical field
The utility model relates to the auto parts and components field, relates in particular to a kind of anti-shake apparatus that is used for the inner hush tube of automotive power steering high-pressure oil pipe.
Background technique
In the automobile hydraulic electric power steering system, its high-pressure oil pipe assembly generally adopts a kind of hush tube (volute) to reduce the noise that steerig pump produces at present.But arrange and the needs of system matches according to car load, that some hush tube designs is very long, in sebific duct the jitter amplitude sebific duct inwall that weares and teares greatly, easily, thereby influence system oil pressure and noise reduction.
The model utility content
At above defective, the purpose of this utility model provides a kind of anti-shake apparatus that is used for the inner hush tube of automotive power steering high-pressure oil pipe, to solve that the hush tube shake causes the oil pressure shakiness, noise is big even wearing and tearing sebific duct inwall causes the problem of system leak.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of anti-shake apparatus that is used for the inner hush tube of automotive power steering high-pressure oil pipe, comprise by metal steel bushing and liner and forming, be with liner on the hush tube and be arranged at high-pressure rubber pipe and liner between, be positioned at the outside of high-pressure rubber pipe and metal steel bushing by low-carbon (LC) cold drawing punching press drawing and forming be installed with inboard liner corresponding position.
The beneficial effect that is used for the anti-shake apparatus of the inner hush tube of automotive power steering high-pressure oil pipe described in the utility model is: can obviously control oil pressure stability in the power steering system, improve the situation of steering wheel rotation steering effort inequality, reduce the noise that oil pump produces; To preventing that the sebific duct inwall from being shaken wearing and tearing for a long time by hush tube certain prevention effect is also arranged, increased the whole system Security; Help solving that the hush tube shake causes the oil pressure shakiness, noise is big even wearing and tearing sebific duct inwall causes the problem of system leak.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the described outside schematic representation of anti-shake apparatus that is used for the inner hush tube of automotive power steering high-pressure oil pipe of the utility model embodiment;
Fig. 2 is the described anti-shake apparatus broken section structural drawing that is used for the inner hush tube of automotive power steering high-pressure oil pipe of the utility model embodiment.
Among the figure:
