Embodiment Construction

[0029]The present invention will be further described below in conjunction with embodiments and drawings.

[0030]In this embodiment, the central drive system is applied to the rear wheels of an electric two-wheeled vehicle as an example for description.

[0031]Such asfigure 1 As shown, a symmetrical dual-motor central drive system based on an intelligent transmission system. The main components involved in the system are: central output part 4, box A, motor 1, reduction mechanism 6, cam clutch mechanism 7, output shaft 3 , Reduction assembly 8, input gear 2, hub 9, wherein the motor 1, reduction assembly 8, input gear 2, reduction mechanism 6, cam clutch mechanism 7 and output shaft 3 constitute the variable speed drive device of the drive system, and are arranged in box A Inside.

[0032]Such asimage 3 As shown, the number of boxes A is two groups, which are arranged symmetrically on both sides of the central output part 4. The two ends of the central output part 4 are supported in the tw...

Abstract

The invention discloses a symmetrical dual-motor central drive system based on an intelligent transmission system, comprising: a central output part; two sets of boxes, which are symmetrically arranged on both sides of the central The two sets of boxes are rotated and installed with output shafts. One end of the output shafts passes through the box and is fixedly connected to the central output part; the variable speed drive device is arranged in the box body, and the variable speed drive device is driven by a motor. Drive, the power is transmitted through the reduction mechanism and the cam clutch mechanism, and the output shaft can be driven to rotate at a low-speed or high-speed transmission ratio. The beneficial effects of the present invention are: when the output load is large, two motors are involved to increase the acceleration performance and climbing performance of the vehicle; when the load is small, only one motor is used for power driving, which can save energy . When applied to electric two-wheel vehicles at the same time, the balance of the wheels is good, which is beneficial to improve the handling and safety of the vehicle.

Description

Technical field[0001]The invention relates to an electric drive speed change mechanism, in particular to a symmetrical double-motor central drive system based on an intelligent transmission system.Background technique[0002]With the continuous deepening of research and development of transmission mechanisms, automatic transmissions capable of automatic shifting have become the mainstream of the market. In recent years, both in the international and domestic markets, the requirements for automatic transmissions have become higher and higher. Because of the quality of automatic transmissions, the driving experience of the vehicle, vehicle performance, energy consumption and other aspects have played a role. The decisive role.[0003]For the research and development of automatic transmissions, in addition to the more common electronically controlled hydraulic automatic transmissions (AT), electronically controlled mechanical automatic transmissions (AMT), and electronically controlled mec...
