Mixed power automobile and mixed power system

Abstract

A hybrid vehicle uses at least two kinds of power, including: engine, starter generator motor, power motor, automatic manual transmission system, battery, automatic switching clutch, and control unit combination. The starter generator motor is coupled with the engine and runs synchronously, and is used to start the engine and also serves as auxiliary power. The automatic manual transmission system is coupled with the power motor, and the automatic manual transmission system shifts gears by controlling the rotational speeds of the starter generator motor and the power motor. The battery supplies power to the starter generator motor and power motor. The automatic switching clutch is coupled between the starter generator motor and the automatic manual gear transmission system, allowing the two to overlap or disengage to change the power form used. The driving state control device sends a signal to the torque speed control device to control the automatic switching of the clutch according to the driving state of the vehicle, so that the engine and the power motor are connected or disconnected.

Description

technical field [0001] The present invention relates to a hybrid vehicle and a hybrid system. Background technique [0002] With the reduction of global crude oil reserves and rising oil prices, countries are actively looking for other alternative energy sources and energy-saving methods to reduce the impact of the oil crisis. [0003] Currently known power sources that can be used by automobiles include fuel engines (diesel, petroleum), solar power systems, and electric drive systems. Among the above-mentioned power sources, some have good power effects and excellent durability, but do not meet the needs of environmental protection; some meet the needs of environmental protection, but cannot achieve the desired power effects. [0004] Taking electric vehicles and solar vehicles as an example, although it is desirable to exclude traditional fuel engines, in fact, the kinetic energy efficiency of these new power sources is limited, so it is not feasible to fully utilize a si...

AI Technical Summary

Problems solved by technology

[0007] 1. Using the speed of a single motor to shift gears, the shifting speed is not fast enough, and the shifting is not smooth, making it difficult to improve the efficiency of the transmission system

[0008] 2. Disc clutches in the prior art can be roughly divided into mechanical type and hydraulic type according to their control methods. The former utilizes an actuating lever to mechanically control the opening and closing of the disc clutch, and its mechanism is quite complicated. , and the cost of parts is relatively high; the latter does not use a lever to actuate the clutch disc, but uses a hydraulic pump to drive the hydraulic cylinder to directly actuate the clutch disc. The cost of the hydraulic system is high and it is easy to leak oil, assembly and maintenance Homework is more difficult

In addition, the actuation speeds of both are relatively slow, which makes the clutch's lapping or disengagement action not smooth enough, resulting in a reduction in transmission efficiency.
