Abstract

The invention relates to a mechanical and electric combined brake energy recovery and secondary traction device, which is suitable for brake energy recovery and secondary traction of various vehicles, tractors, hybrid electric vehicles and electric vehicles, particularly suitable for public transports. The device has the functions of brake energy recovery and secondary traction and is characterized in that: a planet carrier (1) is connected in parallel between an output shaft of a speed changer and wheels; a sun wheel (2) is coaxially connected with a brake drum (9); the brake drum (9) is coaxially connected with a shaft of a motor (10); a brake belt (5) is arranged at the periphery of an internal gear ring (4); the internal gear ring (4) is coaxial with a flywheel (6); a unidirectional overrunning clutch (7) is arranged on the flywheel (6), so that the flywheel (6) rotates only in one direction; and a controller (11) controls the motor (10) and a storage battery (12) and determines that the motor is converted into a working condition of a generator according to a set working condition to charge the storage battery (12) or drives the motor (10) to output power.

Description

technical field [0001] The invention relates to an electromechanical composite braking energy recovery and secondary traction device, which is suitable for braking energy recovery and secondary traction of various automobiles, tractors, motorcycles and other motor vehicles, hybrid vehicles and electric vehicles, especially Suitable for urban public transport vehicles. Background technique [0002] At present, the braking energy recovery of automobiles mainly adopts the working condition of converting the motor into a generator, and converting the braking energy into electric energy and storing it in the battery. The absorption of braking energy by this scheme is limited by the power of the motor itself and the charging current of the battery. After that, there was a scheme of combining storage battery and supercapacitor to absorb the output energy of the generator. Due to the large power and cost of the motor itself, it has not yet reached the point of market application. A...
