Embodiment 1

[0027] Such as figure 1 As shown, the driving system of this embodiment includes an engine 1, an integrated starter generator 2, an automatic clutch 3, an electromechanical coupling mechanism 4, wheels 5, a final reducer-differential 6, a motor controller 7, and a power battery pack 8, Among them: the electromechanical coupling mechanism 4 is composed of a driving motor and a reduction mechanism, the engine 1 and the integrated starter generator 2 are coaxially connected, the integrated starter generator 2 is connected to the active disc of the automatic clutch 3, and the automatic clutch 3 passes through the electromechanical coupling mechanism 4. The drive motor is connected to the reduction mechanism, the reduction mechanism is respectively connected to the drive motor and the final reducer-differential 6, the final reducer-differential 6 is connected to the wheel 5 through the drive axle, and the power battery pack 8 is connected to the motor controller through a cable 7, ...

Embodiment 2

[0041] Such as figure 2 As shown, this embodiment is an optimized solution, and on the basis of Embodiment 1, it also includes a two-speed transmission 9, and the two-speed transmission 9 is arranged between the electromechanical coupling mechanism 4 and the final drive-differential 6 combined mechanism. The input shaft of the high-speed transmission 9 is connected with the reduction mechanism in the electromechanical coupling mechanism 4, and the output shaft of the two-speed transmission 9 is connected with the final drive-differential 7. Other component connections, working modes, and basic control strategies are the same as those in Embodiment 1, and will not be repeated here.

[0042] In this embodiment, due to the existence of the two-speed transmission mechanism, the speed change range is enlarged, and the requirement on the speed range of the driving motor is reduced, so that the speed change control is more flexible.

Abstract

The present invention discloses a hybrid power drive system of motor coach, and belongs to the technological field of vehicle engineering; wherein, an engine is coaxially connected with an integrated starting generator; the integrated starting generator is connected with an automatic clutch driving disc; the automatic clutch is connected with a reducing mechanism through a driving motor; the reducing mechanism is respectively connected with the driving motor and a main reducer-differential; the main reducer-differential is connected with vehicle wheels through a driving bridge; a power battery is connected with a motor controller through a cable; and the motor controller is respectively connected with the integrated starting generator and the driving motor through a cable. The hybrid power drive system maintains the traditional vehicle structure to the greatest extent, and adopts two motors to optimize the working points of the engine, so that the engine can stably operate in the high-efficiency and low-emission regions, in particular in the operating conditions of low-speed city buses.

Description

technical field [0001] The invention relates to a drive system in the technical field of vehicle engineering, in particular to a hybrid drive system for a bus with an integrated starter generator. Background technique [0002] With the tension of world energy and the strengthening of human environmental awareness, safety, energy saving and environmental protection have become the themes of today's automobile development. As one of the new energy vehicles, hybrid vehicles can better solve the above problems. A hybrid vehicle is a vehicle that is jointly driven by an engine and an electric motor system. The engine can be an internal combustion engine using multiple fuels; the motor can be either a permanent magnet motor or an excitation motor, a synchronous motor or an asynchronous motor. The clutch can be a manual clutch or an electronically controlled automatic clutch. For hybrid vehicles with manual gearbox and manual clutch, since the engine is directly connected to the...
