Mixed power automobile and mixed power system

Abstract

The invention provides a mixed power vehicle, which utilizes at least two powers. The invention comprises an engine, a starting generation motor, a power motor, an automatic manual transmission mechanism, a battery jar, an automatic shifting clutch and a control unit combination. The starting generation motor and the engine are coupled and synchronously operated to be used for starting the engine and being taken as the auxiliary power. The automatic manual transmission system is coupled with the power motor; the gear shifting of the automatic manual shifting transmission system is carried out by controlling the rotation speed of the starting generation motor and the power motor. The power supply of the starting generation motor and the power motor is supplied by the battery jar. The automatic shifting clutch is coupled between the starting generation motor and the automatic shifting transmission system which are then connected or disconnected with each other in order to change the applied power state. According to the driving state of the vehicle, a travelling state control device gives signals for the torsion rotation speed control device in order to control the automatic shifting clutch and lead the engine to be connected or disconnected with the power motor.

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.
