Embodiment 1

[0035] Such as figure 1 As shown, the drive system of this embodiment includes engine 1, integrated starter generator ISG2, automatic clutch 3, drive motor 4, planetary gear mechanism 5, wheels 6, final drive-differential 7, motor controller 8, power Battery pack 9, external plug 10, wherein: the engine 1 is coaxially connected with the integrated starter generator 2, the integrated starter generator 2 is connected with the driving disc of the automatic clutch 3, the automatic clutch 3 is connected with the drive motor 4 and the planetary gear mechanism 5, and the planetary The gear mechanism 5 is respectively connected with the driving motor 4 and the final reducer-differential 7, the final reducer-differential 7 is connected with the wheel 6 through the drive axle, and the power battery pack 9 is respectively connected with the motor controller 8 and the external power supply through cables. The plug 10 is connected, and the motor controller 8 is respectively connected 4 wit...

Embodiment 2

[0058] Such as Figure 10 As shown, this embodiment is an optimized solution. On the basis of Embodiment 1, it also includes a two-speed transmission 11. The two-speed transmission 11 is arranged between the planetary gear mechanism 5 and the final drive-differential 7 combined mechanism. The input shaft of the high-speed transmission 11 is connected with the planetary gear mechanism 5 , and the output shaft of the two-speed transmission 11 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.

[0059] 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 invention discloses a mixed power car drive system of a plugging type integrated starting generator in the technical field of vehicle engineering; wherein, an engine is coaxially connected with the integrated starting generator; the integrated starting generator is connected with the driving disc of an automatic clutch; the automatic clutch is connected with a planetary pearing by a drive motor; the planetary pearing is respectively connected with the drive motor and a main reducer-differential mechanism; the main reducer-differential mechanism is connected with a wheel by a drive axle; a power battery is respectively connected with a motor controller and an external power plug by cables; the motor controller is respectively connected with the integrated starting generator and the drive motor by cables; the outer gear ring of the planetary pearing is fixedly connected with a car frame; the invention maintains the traditional vehicle structure to the utmost extent and carries out optimization on the working points of the engine by a double-motor to lead the engine to run stably in an area with high efficiency and low discharge; the system of the invention is especially suitable for the operation of urban low speed bus working condition.

Description

technical field [0001] The invention relates to a car drive system in the technical field of vehicle engineering, in particular to a plug-in integrated starter-generator hybrid car drive system. 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. A plug-in hybrid vehicle, namely PHEV (Plug-in Hybrid Vehicle), can use a household power socket (such as a 220V power supply) to charge the battery while having the advantages of a common hy...
