Problems solved by technology

[0006] The stability of narrow and long vehicles depends on the number and arrangement of the wheels of the chassis, but the unavoidable problem is that the center of mass of the whole vehicle is increased due to the narrow and long body, which has a huge difference from the stability of traditional cars. The position of the center of mass The swing of the vehicle will directly affect the driving stability of the vehicle. On the other hand, the deflection of the center of mass can also be used to achieve the purpose of stable control.

Abstract

The invention provides a steering driving device. The steering driving device comprises a transmission gear, a first driven gear, a planetary gear train, an assisting motor and a bevel gear. Meanwhile, the invention provides a narrow and long tricycle comprising the steering driving device. The steering driving device is novel in structure and more convenient and flexible to operate, is applied tothe narrow and long tricycle with two wheels on the front portion and one wheel on the rear portion and can meet the requirement for controlling a vehicle body to actively incline. Accordingly, the tricycle can automatically adjust the inclination angle according to the intention of a driver in the driving process and meet the requirement for the control stability at different vehicle speeds.

Description

technical field [0001] The invention belongs to the field of steering transmission devices, and in particular relates to a steering transmission device and a narrow and long tricycle including the steering transmission device. Background technique [0002] Electric vehicles are one of the main types of vehicles that have been used in urban transportation to reduce pollution from motor vehicles in the past decade. One type of electric vehicle is derived from two-wheeled bicycles and motorcycles, and the electric drive power system is added to become the main short-distance transportation; the other type of electric vehicle is based on the traditional internal combustion engine vehicle, replacing the electric vehicle as the power source. electric car. In addition, some vehicles used to assist the disabled and special vehicles in the venue are also powered by electric power and have gradually become a means of transportation for urban road travel. [0003] Electric bicycles a...
