Embodiment approach

[0053] As an optional embodiment of the present invention, the rotor assembly 3 further includes a permanent magnet;

[0054] The permanent magnet is arranged at the main body of the positive displacement pump, and performs preliminary intervention on the magnetorheological fluid medium in the positive displacement pump; the electromagnetic coil 41 is arranged at the orifice, and convects the magnetic flow flowing through the orifice. The concentration of the variable fluid medium can be precisely regulated.

[0055] As an optional embodiment of the present invention, a limiting protrusion and / or a limiting groove are provided on the outer side of the sealing assembly;

[0056] The limiting protrusion runs through the electromagnetic coil 41 to prevent the electromagnetic coil 41 from slipping relative to each other;

[0057] The limiting groove accommodates the electromagnetic coil 41, the shape and size of the limiting groove match the electromagnetic coil 41, the electroma...

Abstract

The invention relates to the technical field of mechanical transmission, in particular to a multi-stage retarding device. The multistage retarding device comprises a sealing assembly, a stator, a rotor assembly and a medium adjusting assembly. Liquid is contained in the sealing assembly, the stator and the rotor assembly are combined to form a positive displacement pump, a throttling hole is formed in a liquid outlet of the positive displacement pump, the medium adjusting assembly changes the throttling damping effect of the throttling hole by adjusting the viscosity of a medium, and the rotor assembly is connected with an external part to be retarded. An external part to be retarded drives the rotor assembly to rotate, high pressure is formed at the liquid outlet, resistance is generated under the throttling effect of the throttling holes, mechanical energy of the rotor assembly is converted into pressure potential energy of liquid, then the pressure potential energy is converted into heat energy, and braking force is generated. According to the multi-stage retarding assembly, energy conversion is conducted through mechanical energy of the part to be retarded, retarding braking is achieved, and the energy-saving effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a multi-stage retarder. Background technique [0002] There are many intersections on urban roads, dense bus stops, and a large passenger flow. Buses often have to brake frequently; mountainous roads are steep and have many sharp bends. Medium and large trucks and buses that have been driving on mountainous roads for a long time also often need to brake. [0003] When the brake works frequently for a long time, it will cause rapid wear of the brake shoe, short service life of the brake friction plate, and the loss of braking force or a sharp drop in braking performance due to the thermal degradation of the brake, which has also become the main cause of traffic accidents. Therefore, it is necessary to be equipped with an auxiliary braking system. [0004] As an auxiliary braking part of the vehicle, the retarder acts on the transmission system of the original vehi...
