Commercial vehicle power output system

Abstract

The invention discloses a commercial vehicle power output system which comprises an engine, a power generator and a gearbox, wherein a power shaft on the power generator forms a power generation rotor and is used as a driving power output shaft; the output shaft of the engine is in transmission connection with the front end of the power shaft of the power generator; the rear end of the power shaft of the power generator is in transmission connection with the input shaft of the gearbox through a flywheel and a clutch in match; the power generator is used for providing power to a driving motor; the driving motor is used for providing power to a system installed in a commercial vehicle; and the output shaft of the gearbox is used for driving a chassis driving system of the commercial vehicle. As power is provided to the chassis and the system of the commercial vehicle from single engines respectively, the use property of the whole vehicle is improved.

Description

technical field [0001] The invention relates to the field of commercial vehicles, in particular to a commercial vehicle power output system. Background technique [0002] The traditional commercial vehicle engine power output device is: after the engine, a centrifugal clutch is installed between the flywheel and the gearbox to drive the chassis. The power output system has high stability, but it can only support one output, specifically the driving power output in the field of commercial vehicles. [0003] In the power output system of commercial vehicles, it is generally used to set a side power take-off port on the gearbox, but on the one hand, the output power (torque) of the power take-off port is relatively small, and it is still unable to provide the power demand to replace the secondary engine of the dual-engine model. On the other hand, the rotational speed of the side power take-off port has a fixed speed ratio with the gearbox, and has a great influence on the rot...

Problems solved by technology

[0003] In the power output system of commercial vehicles, side power take-off ports are generally used on the gearbox, but on the one hand, the output power (torque) of this power take-off port is relatively small, and it is still unable to provide the power demand to replace the secondary engine of the dual-engine model

On the other hand, the rotation speed of the side power take-off port has a fixed speed ratio with the gearbox, and has a great influence on the engine speed.
