Problems solved by technology

[0006] In order to overcome the mechanical transmission system existing in the hybrid electric vehicle (HEV) such as: power → clutch → transmission → transmission shaft → final drive → differential → half shaft → wheel scheme, many and heavy mechanical Disadvantages of the transmission system; the disadvantages of the planetary gear mechanical structure in the electric wheel have a large noise; the disadvantages of foreign in-wheel motors and HEV generator output power cannot be directly used, which reduces energy efficiency

Embodiment Construction

[0069] If implement HEV wheel hub driving device of the present invention by existing miniature car, when selecting Alto miniature car to transform and implement, then engine 8 can select Chunlan CL250 series motorcycle high-speed engine for use, 250mL water-cooled four-stroke, electric spray twin-cylinder, maximum rotating speed can be Up to 12000r / min, the use of this high-speed small engine can not only reduce the weight and size of the engine itself, but also reduce the volume and weight of the generator; the disadvantages are: to strengthen the air cooling and improve the noise generated by the exhaust pipe, It is allowed to transform the exhaust pipe according to the exhaust structure of the automobile engine on the mini-car. Within the range of allowable power loss, the noise of the exhaust pipe can be greatly reduced, and the motor / generator is installed on the output shaft of the engine.

[0070] The structural size of the hub motor is designed according to the inner c...

Abstract

A wheel hub driver system of hybrid-type electric vehicle (HEV) is composed of engine, motor / electric generator, hub motors, inverter controller, master controller, SCR switch, and sucking capacitors.

Description

Technical field [0001] The utility model relates to a hybrid electric vehicle (HEV) hub driving device, which belongs to an electric transportation vehicle. Background technique [0002] A hybrid electric vehicle (HEV) is a model between a fuel engine drive and an on-board battery drive, and it is also a transition product from a fuel engine vehicle to a pure battery EV electric vehicle. Due to the current shortage of petrochemical energy in the world and it will be exhausted in a few decades, the application of pure battery energy in EV electric vehicles is still in the immature stage of technology; in order to reduce the excessive consumption of petrochemical energy, supplementary battery energy technology The immature defect, the introduction of hybrid electric vehicles (HEV), is a hot spot in current research and development. HEV vehicles of the prior art mainly include: series hybrid electric vehicle (SHEV), parallel hybrid electric vehicle (PHEV) and hybrid (series, p...
