Electric driving and braking integrated device

Abstract

The invention relates to an electric driving and braking integrated device which comprises tire bodies. Central rotary shafts on the inner sides of the tire bodies are sleeved with rotary supporting structures, the rotary supporting structures are regular polygon structures, the area between every two adjacent corners is fixedly provided with a piece of magnetic steel, the two sides of each rotary supporting structure are respectively provided with a set of silicon steel sheets and a coil, and the peripheries of the rotary supporting structures are jointly covered with an outer-layer sealing frame. Magnetic force is generated by the coils, the magnetic force is utilized for carrying out driving or braking, the self weight and the structure of a car body are reduced, starting response time is shortened, and maintenance is facilitated. Each wheel can be freely controlled to be driven or braked, and on-site turning can be achieved under the condition of safety running. Noise, harmful gas and dust are avoided, driving and braking are integrated, and rotating speed and the braking torque can be controlled through currents. Non-contact type braking is achieved, and running is stable. The adopted magnetic steel is thickened, two sets of coils are adopted by each tire, double braking capacity is achieved, and it means that the braking force is backed up.

Description

technical field [0001] The invention relates to an integrated electric drive and brake technology, in particular to an integrated electric drive and brake device used for tires of automobiles, airplanes and other vehicles. Background technique [0002] Drive mode refers to the type of engine and how the engine is arranged. The driving and braking device of the tire is used in vehicles such as automobiles and airplanes. The common tire brake is a disc brake; the disc brake is made of alloy steel and fixed on the wheel. It rotates with the wheel and is controlled by hydraulic pressure. When braking, The oil is pressed into the inner and outer two-wheel cylinders, and the pistons press the two brake blocks against the brake disc under hydraulic pressure to generate frictional torque for braking. The advantages of the disc brake are: the area of ​​the working surface of the brake friction pad is small, the heat dissipation is better, and the braking torque has nothing to do wit...

AI Technical Summary

Problems solved by technology

The advantages of the disc brake are: the area of ​​the working surface of the brake friction pad is small, the heat dissipation is better, and the braking torque has nothing to do with the forward and backward driving of the car; the disadvantage is that the rotating part of the brake is composed of two sticky The friction plate of the friction lining can slide back and forth on the spline shaft, and the vehicle can be stopped in a very short time during braking. At the same time, the inclination angle of the ball groove on the pressure plate is limited, so the braking will not be smooth. In addition, the The brake is braked by friction torque, the friction loss is large, the cost is high, and the friction will generate a lot of dust, resulting in environmental pollution
