Auxiliary braking system of centrifugal hydraulic light vehicle

Abstract

The invention relates to an auxiliary braking system of a centrifugal hydraulic light vehicle. The auxiliary braking system comprises a hydraulic motor, a speed reduction transmitting device, a rotation speed sensor, a control unit, a magnet coil, a centrifugation device and a flow control valve, wherein the hydraulic motor is connected with the speed reduction transmitting device, the speed reduction transmitting device is connected with wheels of the vehicle, the rotation speed sensor is arranged on the speed reduction transmitting device to detect the rotation speed, the rotation speed sensor is connected with the control unit so as to send the detected rotation speed to the control unit, and the control unit is connected with the magnet coil so as to adjust the current of the magnet coil according to the rotation speed. The magnet coil is sleeved outside a left end part of a valve core of the flow control valve. A rotary shaft of the centrifugation device is arranged on the hydraulic motor, and a sliding sleeve of the centrifugation device is close to the left end part of the valve core of the flow control valve. The auxiliary braking system of the centrifugal hydraulic light vehicle disclosed by the invention has a simple structure, the manufacturing process is mature, the cost is lower, the reliability and the safety of the system are high, and the system can be used as an auxiliary braking system of ordinary small and medium size vehicles, and has long service life.

Description

[0001] technical field [0002] The invention relates to a centrifugal hydraulic light vehicle auxiliary braking system. [0003] Background technique [0004] Generally, friction brakes are the most widely used in existing vehicle brake systems. Friction brakes are further divided into disc brakes and drum brakes. Friction brakes have a simple and mature structure, but they have disadvantages such as easy heat decay and wear of friction parts, so the service life Short; existing large vehicles are usually equipped with hydraulic or electromagnetic retarders to overcome the above shortcomings. The electromagnetic retarder is non-contact and has a long life, but the braking torque is limited, the structure is complicated, the automatic control requirements and the manufacturing cost are high. Difficult to promote, the current hydraulic retarder is too heavy and requires high cooling. It is generally equipped with large vehicles and is not suitable for small and medium vehicl...
