The invention discloses a noise-reducing power steering hose assembly based on high-pressure cotton threads. A power steering tube oil inlet port and an oil outlet tube port are formed in two ends of a hose body respectively; the whole hose body comprises a power steering oil inlet steel tube and a high-pressure cotton thread power steering rubber tube; the joint of the power steering oil inlet steel tube and the high-pressure cotton thread power steering rubber tube is fixed as a whole through a buckling sleeve; a noise reducing tube is arranged in the high-pressure cotton thread power steering rubber tube through a welding lining core. The high-pressure cotton thread power steering rubber tube woven by cotton threads is large in swell capacity, the noise produced when the power steering hose assembly is used during automobile steering is small, and the customer satisfaction is improved; by means of the noise reducing tube structure added to the lining core, the noise produced when the power steering hose assembly is used during automobile steering is reduced greatly, and the customer satisfaction is improved; the impulse test of the high-pressure cotton thread power steering rubber tube can reach 0.4 million times, and the service life of the hose assembly is prolonged.
Description
technical field [0001] The invention relates to the field of automobile power pipelines, in particular to a high-pressure cotton power steering noise reduction hose assembly. Background technique [0002] Conventional commercial vehicle hydraulic power steering hose assembly, hose steel wire weaving, small expansion, loud noise when the car is turned, the customer complained. [0003] Conventional hydraulic power steering hose assembly, the pulse test according to GBT20461-2006 can meet the requirements of 230,000 times; now many automobile OEMs hope to get a big improvement on the basis of national standard performance standards in order to improve service life , while conventional power steering hose assemblies generally cannot meet the lifting requirements. Contents of the invention [0004] The object of the present invention is to overcome the disadvantages of the prior art and provide a high-pressure cotton power steering noise reduction hose assembly. [0005] The...
