Gearbox motor straight rotating device for electric motorcycle tricycle and driving method thereof

Abstract

The invention relates to an electric motor tricycle, in particular to a gearbox motor straight rotating device for an electric motor tricycle, and a driving method thereof. The device is characterized in that the device comprises a motor, an epicyclic gearbox assembly, a differential gearbox assembly, a differential mechanism, a rear bridge casing assembly, a brake drum, a brake mount and a half axle; the horizontal rotating force of the motor is transmitted to the differential gearbox assembly and the differential mechanism connected with the differential gearbox assembly through the epicyclic gearbox assembly, and is converted into a vertical rotating force through the differential mechanism; and the vertical rotating force is transmitted to the half axle which is connected with the differential mechanism. The invention utilizes a gear to replace a chain, the motor is connected with the half axle by a shaft through the epicyclic gearbox assembly, the differential gearbox assembly and the differential mechanism, and the brake drum is connected with a rear bridge outer pipe by a round nut check washer and a round nut. The invention has the advantages of high bearing capacity, small running oscillation, low consumption rate, long service life and the like, is widely suitable for various electric tricycles, and has good market prospect.

Description

technical field [0001] The invention relates to an electric motorcycle tricycle, in particular to an electric motorcycle tricycle gearbox motor straight body rotating device and a transmission method thereof. Background technique [0002] At present, chain transmission is often used between the motor and the rear axle of electric tricycles on the market, but the chain has the disadvantages of small load capacity, easy wear, easy breakage and easy fall off, so there is an urgent need to improve the rotating device between the electric tricycle motor and the rear axle. Improve. And China's patent authorization announcement number is CN200982375Y, and the invention patent "transmission device of electric tricycle" on November 28, 2007 just tries to solve the above-mentioned problem on the date of authorization announcement, and its gist is: a kind of transmission device of electric tricycle, comprising motor, The transmission assembly, the rear wheel shaft, the motor and the r...

AI Technical Summary

Problems solved by technology

This patent uses gears instead of chains, and also uses a differential to connect with the left and right half shafts, but the motor and the rear axle box are directly connected by bolts, and the vibration of the motor will affect the operation of the differential in the rear axle box. Cause certain adverse effects, so that the rear wheels of the electric tricycle do not run smoothly and the carrying capacity becomes smaller
