Magnetic speed reducer for vehicle braking installed on driving shaft

Abstract

The invention relates to a magnetic speed reducer for vehicle braking installed on a driving shaft. A magnetic disk body is fixed on a shaft, magnets which are uniformly distributed in the circumferential direction are embedded in the shaft, a copper disc is installed on the inner face of the copper disc body, a pair of piston rods of a reversing hydraulic cylinder symmetrically installed on a body frame I are in a rigid connection with the outer side of the copper disc body, and a pair of protruding blocks are symmetrically extended in the radial direction and are correspondingly connected into sliding grooves of a connecting body in an inserted mode to carry out axial reciprocating sliding; a hydraulic oil inlet and outlet is changed, the reversing hydraulic cylinder is pushed reversely,and the piston rods pull the cooper disc body to change the distance between the copper disc and the magnets; the magnetic gap between the copper disc and the magnets is small when in braking, magnetic force is generated to enable vehicle wheels to decelerated and carried out breaking, a vehicle water tank pump is started to provide cooling water, and heat absorption is carried out through the cooling water passed through a heat exchanger; meanwhile, a pressure pump is started, the pumped water passes through a heat exchanger water outlet pipe and a water inlet flange opening to enter a cooling water pipe, heat generated during vibration is absorbed by the water, a high temperature water passes through a water return flange opening and a heat exchanger water return pipe and flows back tothe heat exchanger to release the heat; and when not braked, the copper disc and the magnets are at a safe distance, no magnetic force is generated, and the vehicle water tank pump and the pressure pump are closed. The magnetic speed reducer for the vehicle braking installed on the driving shaft has the advantages of being free of pollution and large in braking torque.

Description

technical field [0001] The technology of the invention mainly relates to a magnetic speed reducer, in particular to a magnetic speed reducer for vehicle braking installed on a drive shaft, which belongs to the technical field of magnetic transmission. Background technique [0002] In order to improve the safety performance of heavy-duty vehicles, improve their average driving speed and the reliability of the braking system, vehicles are often equipped with auxiliary braking systems to achieve high-speed deceleration and braking. The hydraulic retarder is one of the main components to achieve auxiliary braking. one. In foreign countries, the hydraulic reducer has been widely guaranteed. Especially in mountainous and hilly areas such as northern Europe, the western United States, and Japan, many buses, engineering vehicles, and heavy-duty transport vehicles are equipped with hydraulic reducers. The design and development of the reducer has formed a complete set of advanced t...

Problems solved by technology

However, the hydraulic reducer has the following application defects: 1. The oil that transmits power works in a high-temperature state for a long time, which is easy to deteriorate, age, and consumes a lot; 2. The working oil in the braking state is too hot and easy to vaporize, so it needs a lot of energy. 3. High temperature working liquid is easy to leak and cause environmental pollution
