An electric tricycle gearbox

Abstract

The invention relates to a gearbox of an electric tricycle. Automatic infinitely variable speed of the gearbox is realized by conducting gear transmission between a motor and an output shaft and introducing an automatic transmission and the like, the electric tricycle is enabled to run safely under the conditions of load bearing, climbing and the like, and simplicity in operation and stability and reliability in performance are achieved. The gearbox is driven by the motor and comprises the output shaft and a box body, the box body comprises an upper cover and a lower cover, and the automatic transmission, a drive gear, a first intermediate gear set, a second intermediate gear set and a driven gear are arranged in the box body. The automatic transmission and the motor are coaxially connected through a spline, and a transmission gear is fixed onto the automatic transmission. The drive gear and the motor are coaxially connected through a spline and positioned above the automatic transmission. The first intermediate gear set comprises a limiting spline, an upper gear, a middle gear and a lower gear, and the upper gear, the middle gear and the lower gear are concentric and coaxial and fixedly sleeve the limiting spline. The second intermediate gear set comprises a rotating shaft, a first intermediate gear and a second intermediate gear, and the first intermediate gear and the second intermediate gear are concentric and coaxial and fixedly sleeve the rotating shaft.

Description

technical field [0001] The invention relates to an electric tricycle, in particular to an electric tricycle gearbox. Background technique [0002] Electric tricycles are mainly suitable for farmers and friends, especially in terms of production needs, but the road conditions in rural areas are complex, such as mud puddles, uneven road surfaces, large slopes, soft roadbeds, etc. At present, electric tricycles are directly driven by motors through motor gears and driven gears The wheels rotate and there is no speed change device, so the speed cannot be adjusted. When driving on these bad roads, the motor will be overloaded and consume a lot of electric energy. , controller, wiring harness and other components. Contents of the invention [0003] The present invention is a gearbox for an electric tricycle. By carrying out gear transmission between the motor and the output shaft, and introducing an automatic transmission etc. at the same time, the automatic stepless speed chan...
