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

The invention provides automatic quantitative oil injection control system and control method for a shock absorber. The control system and the control method can be used for realizing accurately controlling the mass and oil temperature of oil. The automatic quantitative oil injection control system comprises an oil injection module and a temperature control module, wherein the oil injection modulecomprises a quantifying cylinder, an oil tank, and a flow sensing unit; the interior of the qualifying cylinder is separated into a first inner cavity and a second inner cavity by a floating baffle plate; the floating baffle plate can act between the first inner cavity and the second inner cavity according to a preset stroke; the oil tank is connected with the first inner cavity and the second inner cavity respectively; the flow sensing unit is arranged at an oil outlet of the second inner cavity; the temperature control module comprises a refrigerating unit, a heating unit and a temperaturesensing unit; the temperature sensing unit is arranged in the oil tank; the refrigerating unit outputs cold to the oil tank; and the heating unit outputs heat to the oil 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...
