Gear transmission case capable of enabling tricycle to turn round in situ

Abstract

The invention discloses a gear transmission case capable of enabling a tricycle to turn round in situ. The gear transmission case comprises a transmission case body, the top of the transmission case body is provided with an opening, five-axis transmission is adopted in the transmission case body, a driving bevel gear on a driving shaft which transfers engine power is engaged with a driven bevel gear of a first shaft, a transmission gear of the first shaft is engaged with a differential gear of a second gear, a reverse transmission gear of the second shaft is engaged with a reverse gear of a reverse shaft, a switch gear of a third shaft can be engaged with the differential gear and a reverse driving gear of the reverse shaft correspondingly through shifting fork operation of a switch gear,a driving steering gear of the third shaft is engaged with a driving gear of a driving connection shaft, and the driving steering gear is connected with the switch gear. According to the gear transmission case, the structure is simple, arrangement is ingenious, a differential mechanism and the driving steering gear are installed in the case body, and the tricycle can turn round on a small road surface.

Description

technical field [0001] The invention relates to the technical field of gear transmission boxes, in particular to a gear transmission box capable of making a U-turn of a tricycle on the spot. Background technique [0002] Anyone who has lived in the countryside of Guangxi Zhuang Autonomous Region knows that almost every household has crops, and harvesting crops is a relatively heavy work. In order to reduce labor intensity, farmers will choose to use ox carts, horse-drawn carts or other transport machinery to transport harvested crops. When using ox carts or horse-drawn carts to transport crops, the amount of transportation is small and the transportation speed is slow. In order to improve transportation efficiency, farmers have gradually eliminated the use of ox carts or horse-drawn carts and replaced them with motorized tricycles or other agricultural vehicles. However, the original mechanical farming roads in the rural fields of Guangxi are small, and the plots and fields ...

AI Technical Summary

Problems solved by technology

When using ox carts or horse-drawn carts to transport crops, the amount of transportation is small and the transportation speed is slow. In order to improve transportation efficiency, farmers have gradually eliminated the use of ox carts or horse-drawn carts and replaced them with motorized tricycles or other agricultural vehicles. However, the original machine-cultivated roads in the rural fields of Guangxi are relatively small, and the plots and fields are also small, and the road conditions are poor. It is difficult to widen the machine-cultivated roads. Therefore, most of them use motorized tricycles as a means of transportation.

[0003] At present, the existing motor tricycles are almost all with front engine and rear drive, and their turning radius is relatively large, so it is impossible to complete a U-turn on a small tractor road. When a motor tricycle travels on a tractor road, when it needs to make a U-turn, sometimes it needs to travel a long distance In some places, the U-turn can only be completed on a wider road surface, and the turn is completed by relying on the traditional differential. The passing ability is poor, which greatly affects the use of tricycles.
