Synchronous speed changing box for mini-tiller motor vehicle

Abstract

The invention discloses a synchronous speed changing box for a mini-tiller motor vehicle. The synchronous speed changing box comprises a box body and a box body end cover matched with the box body, wherein the box body is internally provided with a shaft I, a shaft II and a middle shaft; each shaft is further provided with a gear-shifting gear set; a backward gear set is further arranged on each of the shaft II and the middle shaft; the backward gear sets are arranged in the box body end cover; the box body end cover is internally provided with a shaft III which is parallel to the middle shaft. The invention provides the synchronous speed changing box for the mini-tiller motor vehicle, which is specially designed according to characteristics of a product, so that the synchronous speed changing box is matched with the product well and a speed changing effect is exerted well; meanwhile, the service life of the product is greatly prolonged and the synchronous speed changing box is good for utilization and popularization of the product.

Description

technical field [0001] The invention relates to a gearbox, in particular to a synchronous gearbox specially used in a power vehicle of a tiller. Background technique [0002] Electric tricycle (Electrically operated tricycle) is a three-wheeled transportation tool that is powered by a battery and driven by a motor to pull goods or people. The electric tricycle adopts tubular large capacity, left and right lining, deep discharge, traction battery, which can meet the requirements of continuous discharge for a long time. But electric tricycle is powered by storage battery, so it has less tractive force, is suitable for advancing on level ground, and the maximum speed per hour when it travels is also difficult to meet people's needs. When the road is undulating too much (such as in hilly areas), the traction force of the electric tricycle cannot meet the traction requirements, which will cause the electric tricycle to stop moving forward, reverse, and even roll over accidents, ...

AI Technical Summary

Problems solved by technology

However, electric tricycles are powered by batteries, so they have less traction and are suitable for traveling on flat ground, and their maximum speed is difficult to meet people's needs.

When the road is undulating too much (such as in hilly areas), the traction force of the electric tricycle cannot meet the traction requirements, which will cause the electric tricycle to stop moving forward, reverse, and even roll over accidents, which poses a great threat to the safety of operators

[0003] Three-wheeled motorcycles are vehicles powered by gasoline engines, but they can only be used for transportation and have no farming function.

However, the existing gearboxes cannot be perfectly matched with them in use, and the greatly shortened service life of the gearbox also prevents the shifting effect of the gearbox from being brought into full play, which is not conducive to the operation and use of the tiller power car.
