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

technical field [0001] The invention relates to a material for a low-pressure rubber hose between an oil pump and a gearbox in an automobile hydraulic steering system, and belongs to the field of polymer materials. Background technique [0002] There are two kinds of hoses in the hydraulic steering system: the high-pressure hose between the oil pump and the gearbox; the low-pressure hose between the gearbox and the fuel tank. In the past, the two rubber hoses used NBR and CR as the inner and outer rubber respectively. The new high-pressure rubber hose composed of HNBR inner layer rubber and CSM outer layer rubber has better heat resistance than the previous rubber hose, and this type of rubber hose is mostly used. But the noise of these two rubber hoses has not been solved. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the existing defects and provide a noiseless low-pressure rubber hose between the oil pump and the...
