Abstract

The invention discloses a low-pressure rubber pipe between an oil pump and a gearbox in an automobile hydraulic steering system. The low-pressure rubber pipe comprises, by weight, 100 parts of epichloro-hydrin rubber, 10-25 parts of graphite, 10-15 parts of diethanolamine borate and 2-7 parts of glass fibers. The low-pressure rubber pipe between the oil pump and the gearbox in the automobile hydraulic steering system does not need to be divided into an inner layer and an outer layer and is integrally formed; meanwhile, a composite material is adopted, by means of organic and inorganic materials, good heat resistance of the low-pressure rubber pipe is guaranteed, and no noise is generated.

Description

Low pressure hose in a kind of car hydrostatic steering system between oil pump and gearbox
Technical field
The present invention relates to the material of the low pressure hose in a kind of car hydrostatic steering system between oil pump and gearbox, belong to polymeric material field.
Background technique
Hydraulic steering system has two kinds of sebific ducts: the high-pressure rubber pipe between oil pump and gearbox; Low pressure hose between gearbox and fuel tank.Past, two kinds of sebific ducts made internal layer and outer layer glue with NBR and CR all respectively.The novel high-pressure sebific duct be made up of HNBR hose lining and CSM outer layer glue is better than sebific duct heat resistance in the past, many employings this kind of sebific duct.But the noise of these two kinds of sebific ducts is always unresolved.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides the low pressure hose between oil pump and gearbox in a kind of noiseless car hydrostatic steering system.
Object of the present invention carrys out specific implementation by the following technical programs:
A low pressure hose in car hydrostatic steering system between oil pump and gearbox, each component of its material by weight, crosses epichlorohydrin rubber 100 parts, graphite 10-25 part, diethanol amine borate ester 10-15 part, glass fibre 2-7 part.
Preferably, the low pressure hose in above-mentioned car hydrostatic steering system between oil pump and gearbox, each component of its material by weight, crosses epichlorohydrin rubber 100 parts, 18 parts, graphite, diethanol amine borate ester 12.5 parts, 4 parts, glass fibre.
Beneficial effect of the present invention:
Low pressure hose in car hydrostatic steering system provided by the present invention between oil pump and gearbox, need not be divided into inside and outside two-layer, one-body molded, meanwhile, composite material is adopted, by the cooperation of organic-inorganic material, not only ensure that the good resistance to heat of low pressure hose, and produce without voice.
