Problems solved by technology

In this way, in the cab of the whole vehicle, there are two shift handles, that is, the five forward gears of the internal combustion engine, and the four forward gears of the four-speed gearbox. According to the arrangement and combination, the driver has 20 gears to choose from. , in the process of driving, the driver and passengers cannot accurately match the speed ratio, and it is easy to cause gear damage due to improper operation, and the quality hidden danger of wet clutch plate ablation
In addition, the maximum output torque of the internal combustion engine can reach 200N.m, which is already far higher than the input torque of the four-speed gearbox, which will increase the failure rate of the gearbox
[0007] Furthermore, no matter which of the above three transmission systems is used, the actual working condition of the internal combustion engine cannot work under the optimal design condition when the internal combustion engine is running at a high speed, which not only causes waste of power and torque reserves of the internal combustion engine At the same time, it will increase the fuel consumption of the internal combustion engine. Long-term high-speed operation will cause the temperature of the internal combustion engine to rise and the lubrication performance to decrease, which will easily cause damage to key parts of the internal combustion engine.

Abstract

The invention discloses a drive system of an internal combustion engine for a motor tricycle. The drive system is characterized by comprising the internal combustion engine (1), a gearshift mechanism (2), a clutch (3), a transmission box (4) and a rear axle (5) which are sequentially connected according to a drive sequence. By using the drive system disclosed by the invention, the mechanical efficiency and the power of the motor tricycle and the drive system thereof are improved and the oil consumption is reduced.

Description

[0001] Technical field: [0002] The invention relates to a three-wheeled motorcycle, in particular to a transmission system of an internal combustion engine for the three-wheeled motorcycle. [0003] Background technique: [0004] At present, the three-wheel motorcycle internal combustion engine all adopts the existing two-wheel motorcycle internal combustion engine, and then combines the external reverse gear and the rear axle to form the transmission system of the three-wheel motorcycle. Yet three-wheeled motorcycle volume and load etc. are all far greater than two-wheeled motorcycle, and required power is also far greater than two-wheeled motorcycle, and directly adopting its internal combustion engine will make a lot of performance parameters fail to reach use requirement. In addition, with the traditional transmission system, due to the position of the output of the internal combustion engine and the installation position of the reverse gear, the main reducer is left-shif...
