Problems solved by technology

This increases the difficulty of driving, and the driving stability of the three-wheeled vehicle itself is relatively poor. If a manual shift mechanism is installed, this will increase the difficulty of driving during driving, which will bring certain hidden dangers to driving safety.
[0003] Moreover, in the existing power transmission device, often only two gears can be shifted, which cannot well adapt to the actual driving needs of the vehicle.

Embodiment Construction

[0024] As shown in the figure, the power transmission device can be applied to electric two-wheel vehicles and electric vehicles with more than two wheels, and is used for automatic gear shifting during the running of the vehicle.

[0025] The structure of the power transmission device includes a power input shaft 10 and a power output shaft 1. The outer circumference of the power input shaft 10 is fixedly provided with a main driving gear 9, and the outer circumference of the power output shaft 1 is fixedly provided with an active and passive gear 3. A plurality of transmission pairs are arranged on the periphery of the power output shaft 1 and the power input shaft 10. The transmission speed ratios of these transmission pairs are different. Corresponding to transmission pairs with different transmission speed ratios, the power output shaft 1 outputs power at different speeds.

[0026] The transmission pair includes a transmission shaft 5 and an auxiliary driving gear 7 and an...

Abstract

The invention discloses a motor multi-gear power transmission device, and solves the problem that safety cannot be guaranteed because a conventional electric vehicle is complicated in gear shift. The motor multi-gear power transmission device comprises a power output shaft and a power input shaft, wherein a plurality of transmission pairs comprising transmission shafts are arranged at the peripheries of the two shafts in a planetary shape; the transmission pairs have different transmission speed ratios; and a synchronizing ring in each transmission pair can axially slide on the corresponding transmission shaft through a corresponding electric driver, so that power transmission between gears which are movably connected to each transmission shaft in a sleeving manner and the corresponding transmission shaft is realized. For the electric drivers, target control is realized by a vehicle-mounted controller according to a signal of a speed sensor, so that the transmission of large torque and low rotating speed or the transmission of small torque and high rotating speed can be realized when a vehicle runs, advancing demands of the vehicle can be well met, and energy consumption is effectively reduced.

Description

technical field [0001] The invention belongs to the field of power transmission, and in particular relates to a transmission device applicable to an electric vehicle for realizing multi-gear transmission of motor output power. Background technique [0002] The existing electric two-wheeled vehicle is not provided with a shifting mechanism. When the electric vehicle is required to move forward, only the rotation of the handlebar is used to realize the change of the current through the controller, and then the output speed of the motor is changed. For some electric tricycles with large loads, this control method cannot well adapt to the problems that electric vehicles face during actual driving. On some electric vehicle tricycles, also be provided with some manual gearshift mechanisms sometimes, but manual gearshift mechanisms generally need both hands and feet to realize the conversion of gear positions when operating. This increases the difficulty of driving, and the drivin...
