Problems solved by technology

The oil-gas spring needs not only a one-way valve to control the flow direction of the liquid, but also an unloading valve to protect the oil-gas spring when the impact is too large. If the split installation is adopted, the structure will be complicated, t...

Abstract

The invention discloses a hydro-pneumatic spring base assembly integrating a vehicle height sensor and a valve bank. The hydro-pneumatic spring base assembly comprises a base arranged at the upper end of a cylinder barrel in a sealed mode, and further comprises the vehicle height sensor and the valve bank which are arranged in the cylinder barrel, wherein the valve bank comprises an annular upper pressing disc, a valve seat and a lower pressing disc which are sequentially and coaxially connected from top to bottom, the upper pressing disc is fixedly connected with the base, the circumference of the valve seat is connected with the cylinder barrel in a sealed mode, an unloading through hole and a one-way through hole which are used for communicating the inside and the outside of the valve bank are formed in the valve seat, and an unloading valve assembly is arranged between the upper pressing disc and the valve seat; and a one-way valve assembly is arranged between the valve seat and the lower pressure disc. According to the assembly, after the vehicle height sensor is installed on the base, the valve bank is arranged around the vehicle height sensor, the radial space in a hydro-pneumatic spring is fully utilized, the vehicle height sensor and the valve bank are integrated in the hydro-pneumatic spring, the use environment is optimized, and the reliability and precision of the sensor are greatly improved.

Description

technical field [0001] The invention relates to auto parts, in particular to an oil-pneumatic spring base assembly integrating a vehicle height sensor and a valve group. Background technique [0002] In the field of heavy-duty off-road vehicles and special equipment vehicles, the oil-pneumatic spring is a kind of elastic damping element of vehicle suspension with high energy density and excellent performance. The damping characteristics of ordinary oil and gas springs are invariable, and ordinary oil and gas springs are also called passive suspension vehicles. The technology of the adjustable damping shock absorber has become mature now. The Chinese invention patent application with the publication number CN109611493 A discloses a damping adjustment device for the oil-pneumatic spring. On the basis of the original structure of the oil-pneumatic spring, a newly added An oil circuit is used as the return oil circuit of the oil-gas spring, and the pilot proportional pressure r...
