Abstract

The invention discloses a hydraulic retarder control system and a control method. The control system comprises a magnetic exchange valve controlling a hydraulic retarder. The control system further comprises a hydraulic retarder stepping switch, a control box, a compressed air pipeline, a vehicle auxiliary loading air chamber and a heat exchanger. The control box is connected to the stepping switch of the hydraulic retarder, and the stepping switch provides working signals for the control box. The magnetic exchange valve is connected to the control box, and the control box sends control commands to the magnetic exchange valve. The magnetic exchange valve is connected to the compressed air pipeline. By employing the hydraulic retarder control system, oil can be rapidly charged and discharged for the hydraulic retarder, and the oil charging rate of the hydraulic retarder can be continuously adjusted according to retarding requirements, thereby bringing high reliability and convenient control.

Description

Technical field

[0001] The present invention relates to the field of automobile parts and automobile manufacturing, in particular to the field of auxiliary brakes for automobiles-hydraulic retarders for automobiles. technical background

[0002] The safety of automobiles has always been important, especially in today's booming automobile transportation industry, which requires vehicles to have higher operating efficiency. Therefore, the quality of vehicles increases, the speed of vehicles increases, and the kinetic energy of vehicles increases exponentially. The braking ability of the service brake cannot be improved simultaneously due to the limitation of many factors. When the brake is subjected to long-term continuous braking and high-speed braking on a long slope, the brake is subjected to a strong load of huge kinetic energy transformed into heat energy, brake linings and brake drums The temperature can be as high as 1000Β°C. At such a high temperature, not only the braking ...
