Dual-channel continuously variable transmission fuel vehicle power system

Abstract

The invention provides a double-channel stepless speed change power system for an oil-fueled automobile and relates to a stepless speed change power system applied to the oil-fueled automobile. The double-channel stepless speed change power system comprises an internal combustion engine, a clutch I, a connection gear II, a continuously variable transmission, a connection gear I, a gear connectionpart I, a clutch II, a main speed reducer, a speed measuring device and a gear connection part II. A torque transmission channel I is used for transmitting a torque of the internal combustion engine by adopting a friction force, and a torque transmission channel II is used for transmitting the torque of the internal combustion engine by adopting a gear; the two torque transmission channels are used for driving two input ends of the main speed reducer respectively to form the oil-fueled automobile power system capable of realizing stepless speed change; the size of the torque transmitted by thepower system and the response speed performance are better than those of a common continuously variable transmission, so that zero-rotating-speed output can be realized when the internal combustion engine is not shut down; and if the oil-fueled automobile is configured with the power system, the internal combustion engine can be operated in an economical rotating speed region all the time, so that the fuel efficiency of the oil-fueled automobile can be improved and the emission of pollutants is reduced.

Description

technical field [0001] The present invention is a dual-channel continuously variable speed fuel vehicle power system, which relates to a continuously variable speed power system applied to fuel vehicles, in particular to a bevel tooth differential speed reduction mechanism and gear connection parts using steel ball speed regulation One transmits the torque of the internal combustion engine to drive the input end 1 of the double bevel differential speed reduction mechanism, and uses the gear connection part 2 to transmit the torque of the internal combustion engine to drive the input end 2 of the double bevel differential speed reduction mechanism to form two torque transmission channels Dual-channel continuously variable fuel vehicle power system. Background technique [0002] At present, the mileage of pure electric vehicles is short. Before the breakthrough of battery energy storage technology, hybrid electric vehicles have high practical application value, but the cost of...

AI Technical Summary

Problems solved by technology

The steel ball speed-adjusting bevel gear differential speed reduction mechanism uses friction to transmit torque. When the internal combustion engine accelerates rapidly, the friction surface will still slip, resulting in acceleration lag and affecting the driving experience.
