Oil-power hybrid transmission converter for motor vehicle

Abstract

The invention discloses an oil-power hybrid transmission converter for a motor vehicle. An input shaft, a driving bevel gear and an output shaft support a shell through a bearing respectively; one end of the input shaft is provided with an internal tooth structure; one end of the output shaft is provided with a spline section; a shaft neck of the end is matched with the input shaft through the bearing; a driven bevel gear is idly sleeved on the output shaft and is engaged with the driving bevel gear; a synchronizing gear is arranged between the input shaft and the driven bevel gear and is matched on the output shaft through an internal spline; the synchronizing gear can axially move to make external teeth at two ends be engaged with the input shaft or internal teeth of the driven bevel gear; a fork shifting mechanism is arranged in the shell; a shifting fork of the fork shifting mechanism is in clearance fit in an annular groove of the synchronizing gear; and a control rotation shaft of the fork shifting mechanism extends out of the shell and is used for connecting an operating device. Due to artificial manual control and operation, power transmission is converted between a first power device and a second power device stably and smoothly, power devices are not needed to be stopped working, and the conversion operation is easy and durable.

Description

technical field [0001] The invention relates to a power transmission converter of a hybrid electric vehicle, in particular to an oil-electric hybrid transmission converter of a motor vehicle. Background technique [0002] The power conversion of the existing gasoline-electric hybrid vehicles usually adopts an electric control system to control the switching between the internal combustion engine and the electric motor. For example, the technology disclosed in "A Fuel-Electric Integrated Hybrid Power System for Light Vehicles" with the publication number CN1583444A, the technology includes an internal combustion engine power system, an electric drive system, a mechanical transmission system, and an integrated control system. The internal combustion engine power system and the electric drive system are connected, and the internal combustion engine power system is connected with the electric drive system. Its mechanical transmission system includes two modes of coupled transmi...

Problems solved by technology

However, there is a problem in this system, that is, the system needs to complete many steps when starting the engine while driving. First, the main clutch must be disengaged, and then the motor must be controlled to decelerate to zero speed. After controlling the increased clutch coupling, the motor shall be accelerated to drive the engine. The shaft rotates, the main clutch is coupled after the engine starts, and the operation and control are complicated. During this period, for about two or three seconds, the entire system has no power output, the driving performance of the vehicle decreases, and the driver and passengers feel obvious. In particular, the complex operation control process can easily lead to distraction of the driver and cause traffic accidents.

Moreover, the above-mentioned hybrid electric control system needs to rely on the integrated electronic control system for control. The integrated electronic control system has a complex structure, high cost, and is prone to failure; especially when the integrated electronic control system is used in the harsh working conditions of the hybrid electric control system. When the three-wheeled motorcycle is on, it is more likely to be damaged, resulting in the failure of the three-wheeled motorcycle to drive normally and traffic accidents
