Hybrid-power automobile special-use chassis

Abstract

The invention discloses a special chassis for hybrid electric vehicle. It is composed of frame, front wheel, pile, rear wheel, driving motor, double-output back axle, gear box, engine, controller, power distribution clutch and generating set. Taking the double-output back axle as the center, the driving motor, gear box, power distribution clutch and generating set compose integration. One output of the back axle connects with the engine by the gear box and the other output links the driving motor which locates on the middle part of the frame. Compare to the general hybrid electric vehicles, the invention realizes the postposition or front position of the engine by the double-output back axle, which can shorten the whole length of the classis by 800mm-1000mm. It benefits the rational distribution of axis load, adds stationarity and comfort during the driving and reduces resistance, energy consuming or gas emission. The motor and the generator in the invention all can work independently when the other products fault, which can keep the normal operation of the vehicles.

Description

Technical field: [0001] The invention relates to an energy-saving and environment-friendly passenger car chassis with multiple power configurations, in particular to a special chassis for hybrid electric vehicles. Background technique: [0002] In order to meet the needs of energy saving and environmental protection, the industry is vigorously developing and developing hybrid city buses. And the hybrid type city bus that generally develops is generally all equipped with engine and electric motor in the driving system of passenger car, and its engine and electric motor all generally all be connected in series on the same transmission shaft, so engine and electric motor can only be linked and can not drive independently separately. However, when the engine is driven independently, even if the motor is not directly driven, it must be used as an auxiliary drag to generate resistance and consume energy, which not only brings about waste of energy, but also affects the operation o...

AI Technical Summary

Problems solved by technology

The commonly developed hybrid city buses are generally equipped with an engine and an electric motor in the driving system of the bus, and the engine and the electric motor are generally connected in series on the same transmission shaft, so the engine and the electric motor can only be linked and cannot be driven independently

However, when the engine is driven independently, even if the motor is not directly driven, it must be used as an auxiliary drag to generate resistance and consume energy, which not only brings about waste of energy, but also affects the operation of the driving performance of the entire vehicle, failing to achieve energy-saving and environmental protection effects.

In addition, due to the series arrangement of the engine and the electric motor, the rear suspension of the chassis is too long, resulting in unreasonable axle load distribution, resulting in bumpy rear seats and uncomfortable rides.
