Braking device

Abstract

The embodiment of the invention provides a braking device, and belongs to the technical field of non-friction braking. The braking device includes a braking box body, a box cover, shear thickening liquid, two rotor shear rods, a stator shear rod, a shaft and a ventilation plug; a stator and rotors are placed inside the box body, the inside of the box body is filled with the shear thickening liquid, and the rotor shear rods and the stator shear rod are immersed in the shear thickening liquid. The rotor shear rods are fixed to the shaft in an assembled mode. The stator shear rod is placed at theposition, between the two rotor shear rods, inside the box body and is separated from the shaft. The physical characteristics of the shear thickening liquid (non-Newtonian fluid) are used, a reduction gearbox body is filled with shear thickening liquid, shearing is performed in the shear thickening liquid through the rotors, the viscosity of the liquid changes under impact, physical characterization changes from a liquid phase to a solid phase, at the moment, the rotation of the rotors is subjected to great resistance, and the resistance output is achieved through the shaft, the rods and other components connected to the rotors to achieve the purpose of braking. The solid-liquid phase transition of the shear thickening liquid is fast and reversible, so that the braking effect and the heatdissipation effect of the braking device are very good. The braking device has the characteristics such as large braking power, high heat dissipation efficiency and high reliability, and is widely used in high-speed and high-power vehicles and industrial fields.

Description

technical field [0001] The invention relates to non-friction braking technology, in particular to a braking device. Background technique [0002] A brake is a device that has the functions of decelerating, stopping or keeping a moving part (or moving machinery) in a stopped state. It is a mechanical part that stops or slows down the movement in the machine. Commonly known as brakes, brakes. Some brakes are also equipped with an automatic adjustment device for the brake clearance. In order to reduce the braking torque and structural size, the brakes are usually installed on the high-speed shaft of the equipment, but large equipment with high safety requirements (such as mine hoists, elevators, etc.) etc.) should be installed on the low-speed shaft close to the working part of the equipment. For cars that often travel in mountainous or hilly areas, in order to reduce or maintain a stable vehicle speed for a long time and reduce or reduce the brake load when going down a lon...

Problems solved by technology

However, the design of the existing braking or retarding device will cause the control components to heat and wear, and the temperature will rise sharply to affect the braking effect. It is very unsuitable for the auxiliary braking system of heavy trucks and trains.
