Three-in-one device for realizing low-speed braking energy recovery

Abstract

The invention relates to a three-in-one device for realizing low-speed braking energy recovery, which comprises a fixed speed ratio gearbox, a generator and a motor controller, the fixed speed ratio gearbox, the generator and the motor controller form a three-in-one assembly, the two ends of the generator are output, one end of the generator is connected with the fixed-speed-ratio gearbox, the other end of the generator is connected with an auxiliary part which can be additionally provided with an air pump, The fixed-speed-ratio gearbox is used for amplifying the low rotating speed of the transmission device and then transmitting the amplified low rotating speed to the power generator so as to increase the rotating speed of the power generator, the power generator is used for recycling energy during braking and conducting power assistance during driving, and the motor controller is used for controlling the power generator to work. The three-in-one device for realizing low-speed braking and energy recovery is high in integration level and can be connected with a power system in various modes, including rear axle input connection and main gearbox power takeoff connection.

Description

Technical field [0001] The present invention relates to the field of new energy ore braking energy recovery techniques, and specifically, a device that realizes a three-speed brake energy recovery three in. Background technique [0002] At present, pure electric or hybrid vehicles have brake energy recovery function, but when the vehicle speed is low, at this time, the speed of the generator is also low, which is not conducive to the recovery of braking energy, which is generally given up the brake energy recovery, Causes waste of energy. Especially in the mine scenario, the low-speed overload of vehicles, mechanical braking causes energy loss and brake wear and overheating. Inventive content [0003] It is an object of the present invention to overcome the shortcomings of the prior art described above, providing a device that satisfies high, high functions and high functionality, good economic performance. [0004] In order to achieve the above object, the implementation of the...
