Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0024] Such as figure 1 , 2 As shown in and 3, a central drive electric drive system for an electric two-wheeled vehicle includes a fixed shaft 2, and the two ends of the fixed shaft 2 can pass through the outer shell 10 and be fixedly installed on the vehicle wheel frame or flat fork 11, and the fixed shaft 2 Used to support the entire electric drive system, the fixed shaft 2 is covered with a rotating sleeve 3 extending along its length. The rotating sleeve 3 rotates relative to the fixed shaft 2 when it is working. Due to the assembly gap between the rotating sleeve 3 and the fixed shaft 2 , the proper amount of bending deformation generated after the fixed shaft 2 is loaded will not affect the transmission accuracy of the system. The motor 4, the hub 5 and the reduction mechanism 6 are arranged on the rotating sleeve 3 in sequence from left to right. Whe...

Abstract

The invention discloses a central drive electric drive system for an electric two-wheeled vehicle. A rotating sleeve is rotationally sleeved on a fixed shaft; a motor, a hub and a speed reducing mechanism are mounted on the rotating sleeve; the speed reducing mechanism transmits the rotation of the rotating sleeve to the hub in a speed reduction manner; a first speed reducing gear, a sliding sleeve and an elastic element are arranged on a speed reducing shaft of the speed reducing mechanism; the sliding sleeve synchronously rotates along with the speed reducing shaft and can axially slide along the speed reducing shaft; the elastic element applies a force for forcing the sliding sleeve to slide towards the direction of the first speed reducing gear; the first speed reducing gear is in running fit with the speed reducing shaft; the ends, close to each other, of the sliding sleeve and the first speed reducing gear are provided with an arc-shaped inwards-concave structure and an arc-shaped outwards-convex structure respectively; the arc-shaped inwards-concave structure and the arc-shaped outwards-convex structure interact and can drive the sliding sleeve to move in the axial directionof the speed reducing shaft; and the sliding sleeve is provided with a detection component used for detecting axial displacement. The central drive electric drive system has the advantages of being high in mechanical transmission efficiency, good in balance, good in controllability, compact in structure and capable of detecting the load of a driving system.

Description

technical field [0001] The invention belongs to the technical field of two-wheeled vehicles, and in particular relates to a central drive electric drive system for electric two-wheeled vehicles. Background technique [0002] The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator, and is widely used in modern machinery. [0003] For example, in the technical field of electric two-wheeled vehicles, the hub motor is directly driven by a low-speed DC motor, and the efficiency is relatively low. The power source is transmitted through the reduction mechanism. However, such an arrangement would make the structure of the entire drive system too bulky and result in poor balance of the...
