An automatic quantitative oil injection control system and control method for shock absorbers

Abstract

The present invention provides an automatic quantitative oil injection control system and control method for a shock absorber, which can precisely control oil quality and oil temperature. The automatic quantitative oil injection control system includes: an oil injection module and a temperature control module; The oil injection module includes: a quantitative cylinder, an oil tank, and a flow sensing unit. The interior of the quantitative cylinder is divided into a first inner cavity and a second inner cavity by a floating baffle, and the floating baffle can be positioned at the second inner cavity according to a preset stroke. The action is performed between the first inner cavity and the second inner cavity, the oil tank is respectively connected with the first inner cavity and the second inner cavity, and the flow sensing unit is arranged at the oil outlet of the second inner cavity place; the temperature control module includes: a refrigeration unit, a heating unit, and a temperature sensing unit, the temperature sensing unit is set in the oil tank, the refrigeration unit outputs cooling capacity to the oil tank, and the heating unit outputs heat to the tank.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorbers, in particular to an automatic quantitative oil injection control system and control method for shock absorbers. Background technique [0002] With the improvement of people's requirements for the comfort of automobile vibration reduction, higher technical requirements are also put forward for the assembly process of shock absorbers. Therefore, it is necessary to carry out dynamometer tests on the assembled shock absorbers. The dynamometer test refers to detecting the curves of compression force and tension force and displacement at different speeds under the detection conditions, so as to judge whether it is qualified. But before the dynamometer test, it is also necessary to carry out an oil injection process on the inner cylinder of the assembled shock absorber. [0003] Among them, the oil temperature and oil quality are very important factors affecting the curve judgment, b...

Problems solved by technology

[0003] Among them, the oil temperature and oil quality are very important factors affecting the curve judgment, but the existing automatic quantitative oil injection control equipment for the automatic oil injection process of the shock absorber adopts the ordinary interrupt control method, which cannot The quality of the oil is accurately controlled, and the oil temperature cannot be controlled. At the same time, once the flow meter used on the automatic quantitative oil injection machine is damaged, it will cause production stop loss
