Abstract
The utility model provides a noise reduction effect is good, simple structure's structure of making an uproar falls in auto steering oil pipe. This structure includes high pressure hose, oise reduction system and choke valve, the oise reduction system is all connected at the both ends of choke valve, oise reduction system and choke valve are arranged in in the high pressure hose. The utility model discloses a structure of making an uproar falls in auto steering oil pipe, two cavitys are kept apart into to high pressure hose to the choke valve, the oise reduction system at choke valve both ends and two cavity space combined action that the choke valve combines high pressure hose, the pulsation decays to the voltol oil, from the pulsation high pressure fluid process of oil pump outflow the utility model discloses an effective hydraulic pressure noise that reduces whole car a steering system behind the structure of making an uproar falls in auto steering oil pipe, can flow with the laminar flow state.
Description
Technical field
The utility model relates to automotive steering oil circuit component technical field, is specifically related to a kind of automotive steering oil pipe denoising structure.
Background technique
Hydraulic power-assist steering system is the most frequently used configuration of automobile, and it is by engine-driving steerig pump, and oil pump sucks to discharge high pressure oil after steering oil for power steering gear and provide power.Steerig pump is vane pump normally, and the oil that vane pump is discharged has pulsation, and in pipeline and commutator, flowing can produce noise.Reduce steering system noise, just need to arrange Denoiser to this this pulsation that decays.At present conventional Denoiser form usually adopts and changes its length or its type, and is arranged on and turns to the mode of the nearly oil pump end of high-voltage tube to realize noise reduction, does not arrange from structure and position and attempts, so noise reduction is limited.
Summary of the invention
The purpose of this utility model proposes a kind of excellent noise reduction effect, the simple automotive steering oil pipe denoising structure of structure.
According to the automotive steering oil pipe denoising structure that the utility model provides, comprise high pressure hose, Denoiser and throttle valve, the two ends of described throttle valve all connect Denoiser, and described Denoiser and throttle valve are placed in described high pressure hose.
Automotive steering oil pipe denoising structure of the present utility model, throttle valve is isolated into two cavitys high pressure hose, the Denoiser at throttle valve two ends and throttle valve are in conjunction with two cavity space actings in conjunction of high pressure hose, high pressure oil pulsation is decayed, from oil pump flow out pulsation high-voltage oil liquid after automotive steering oil pipe denoising structure of the present utility model, can flow out with laminar condition, effectively reduce the hydraulic pressure noise of car load steering system.
Further, the pipe shaft place that described high pressure hose correspondence installs Denoiser and throttle valve is provided with and spacingly tightens cover, to keep sealing and the integrity of high pressure hose.
Further, the two ends of described high pressure hose are provided with and tighten cover for what be connected with high pressure hard tube, increase the connection sealing reliability of high pressure hose and high pressure hard tube.
Specifically, described Denoiser is spirality Denoiser.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The partial enlargement structural representation of Fig. 2 Fig. 1.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and working principle etc. of embodiment of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As Fig. 1,2, automotive steering oil pipe denoising structure of the present utility model, comprises high pressure hose 1, Denoiser and throttle valve 3, and the two ends of throttle valve 3 connect Denoiser 21 and Denoiser 22 respectively, and Denoiser 21 and Denoiser 22 and throttle valve 3 are all placed in high pressure hose 1.Wherein Denoiser 21 and Denoiser 22 are the spirality Denoiser of certain length, and Denoiser 21 and the back-to-back riveting of Denoiser 22 are on throttle valve 3.The pipe shaft place that high pressure hose 1 correspondence installs Denoiser 21 and Denoiser 22 and throttle valve 3 is provided with and spacingly tightens cover 4, the pipe shaft that cover 4 compresses high pressure hose 1 is tightened by spacing, thus fixing Denoiser 21 and Denoiser 22 and throttle valve 3, to keep sealing and the integrity of high pressure hose 1.The two ends of high pressure hose 1 are provided with and tighten cover 6 for what be connected with high pressure hard tube 5, increase the connection sealing reliability of high pressure hose 1 and high pressure hard tube 5.
Claims (4)
1. an automotive steering oil pipe denoising structure, it is characterized in that comprising high pressure hose, Denoiser and throttle valve, the two ends of described throttle valve all connect Denoiser, and described Denoiser and throttle valve are placed in described high pressure hose.
2. automotive steering oil pipe denoising structure according to claim 1, is characterized in that pipe shaft place that described high pressure hose correspondence installs Denoiser and throttle valve is provided with and spacingly tightens cover.
3. automotive steering oil pipe denoising structure according to claim 1, is characterized in that the two ends of described high pressure hose are provided with and tightens cover for what be connected with high pressure hard tube.
