Automobile hybrid drive system

Abstract

The invention provides an automobile hybrid drive system, which belongs to the technical field of automobiles, and solves the problems of complicated system, high difficulty in arrangement and higher cost of the existing hybrid drive system. The automobile hybrid drive system of the invention is arranged on an automobile body, is connected with a transmission shaft connected with a drive wheel, and comprises an engine, a drive motor, a variable-speed clutch, a reinforced starter, a storage battery and the like, wherein the engine is fixedly connected on the automobile body; the rotary shaft of the engine is connected with the input end of the variable-speed clutch; the rotary shaft of the drive motor and the output end of the variable-speed clutch are connected with the transmission shaft; the storage battery is connected with the drive motor; and the rotary shaft of the reinforced starter can drive the rotary shaft of the engine to rotate. The invention has the advantages of small axial dimension, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a power drive system, in particular to a hybrid drive system in an automobile. Background technique [0002] At present, the automobile power drive mechanism is composed of an engine, a clutch, a gearbox, a transmission shaft, and a starting DC motor. When the engine after starting is going to accelerate, it is necessary to increase the accelerator, that is, to increase the amount of oil to increase the engine power to achieve the purpose of acceleration, and at the same time, there is a situation of excess power. In the process of driving, the engine will also have a situation of excess power, which makes the energy not fully utilized. [0003] For this reason, people have proposed various solutions through long-term exploration. For example, people have invented the hybrid drive system. Hybrid vehicles have attracted more and more attention because they have both the advant...

AI Technical Summary

Problems solved by technology

The hybrid powertrain can be designed in many forms of three types: series, parallel and hybrid, but among these three types of hybrid powertrains, the series mode is only suitable for short-distance running vehicles, and the hybrid mode is due to the powertrain drive There are many components, the system is complicated, the layout is difficult, and the cost is high

In addition, the ISG motor is added to the hybrid drive device, resulting in a relatively large axial dimension of the entire power drive device, and relatively high requirements for the layout of the vehicle.
