Heat dissipation device of automobile hydraulic power steering system

Abstract

The invention discloses a heat dissipation device of an automobile hydraulic power steering system. The heat dissipation device comprises a shell and an oil conveying pipe, the shell is arranged on the outer side of the oil conveying pipe in a sleeving mode, an oil outlet connector and an oil inlet connector are arranged at the upper end and the lower end of the oil conveying pipe respectively, and two pressure cylinders are symmetrically arranged on the inner side of the shell; and acting assemblies for absorbing heat are arranged on the inner sides of the two pressure cylinders correspondingly, a mounting plate is fixedly connected to the inner side of the shell, and the space, located on the upper side of the mounting plate, in the shell is filled with water. The heat dissipation deviceis reasonable in design, the pressure cylinders are arranged and filled with the rubber particles and the water, and due to the thermal expansion and cold contraction characteristics of the rubber particles, the rubber particles absorb heat of the oil conveying pipe and pressurize the water in the shell, so that a sliding plate moves upwards under water pressure; the sliding plate moves upwards to drive a spoiler to rotate under the transmission action of a guide rod, a rack plate, a gear and a first rotating shaft, so that the purpose of spoiling is achieved, and the heat dissipation efficiency of water to the oil conveying pipe is improved.

Description

technical field [0001] The invention relates to the technical field of automobile radiators, in particular to a radiator for an automobile hydraulic power steering system. Background technique [0002] The existing automobile power steering system usually adopts a hydraulic power steering device, which is composed of a power steering pump, a steering gear, an oil pump and a hydraulic pipeline. The hydraulic oil is pressurized by the hydraulic oil pump to provide power to the power steering. After the system works for a long time, especially in the case of long-term high-load work, the input energy of the hydraulic oil pump and the heat transfer of the mechanical device will increase the temperature of the hydraulic oil in the hydraulic power steering device. [0003] Due to the high temperature of the hydraulic oil after the car has been driving for a long time, the output pressure of the hydraulic oil pump drops and the liquid volume decreases under the high oil temperature...

AI Technical Summary

Problems solved by technology

[0003] Due to the high temperature of the hydraulic oil after the car has been driving for a long time, the output pressure of the hydraulic oil pump drops and the liquid volume decreases under the high oil temperature working condition, which weakens or even fails the power steering effect, and the driving steering becomes very laborious, and it is even difficult to steer manually, resulting in Driving safety hazards, traditional radiators mostly rely on air-cooling and water-cooling to achieve the purpose of keeping the temperature of the oil pipeline, but long-term use will consume a lot of resources, which will bring losses to people's economy, and when the car is driving on uneven roads, the long-term Time shocks can dislocate parts inside the radiator and prevent it from functioning properly
