Embodiment

[0030] see Figures 1 to 4 , an electric motorcycle internal rotor motor friction plate self-adaptive automatic separation drive assembly, including a drive motor 13, a box body and a main shaft 1 that rotates with the box body and outputs power, and also includes a gear seat 8 and a clutch assembly , one-stage gear 23, transmission unit, one-way gear 11 and one-way limiting helical cam 10.

[0031] Wherein, the box body includes a box body fixing plate 24, a left box body 25 positioned at the left side of the box body fixing plate 24, and a right box body 26 positioned at the right side of the box body fixing plate 24, the right box body 26 and the box body fixing plate 24 Fastening is done with screws.

[0032] The main shaft 1 extends from the left box 25 to the right box 26 and passes through the box fixing plate 24 . A gland 15 fixed by screws is also provided outside the right box body 26 , and a first spindle bearing 16 is installed between the gland 15 and the spindl...

Abstract

The invention discloses a friction plate type self-adapting automatic separation driving assembly of an inner rotor motor of an electric motor cycle. The friction plate type self-adapting automatic separation driving assembly comprises a driving motor, a tank body, and a main shaft which is matched with the tank body in a rotating manner and outputs power, and further comprises a gear base, a clutch assembly, a first-stage gear, a transmission unit, a one-way gear and a one-way limiting screw cam. According to the friction plate type self-adapting automatic separation driving assembly disclosed by the invention, a novel plane type clutch assembly is used for transmitting torque, so that the friction plate type self-adapting automatic separation driving assembly has the advantages of being simple in structure, fast and convenient to assemble, easy to process, good in joint surface, fast in separation, free from impact, stable in torque force value, and the friction area can be infinitely increased. Through adjusting the number of external tooth friction pieces and the number of inner tooth liners and / or adjusting torque, nuts are adjusted to meet different requirements for the torque; when the torque is greater than a calibration value of the clutch assembly, the one-way limiting screw cam drives a thrust limiting screw cam, so that the external tooth friction pieces and the inner tooth liners are mutually loosened, the situation that the pressure in an axial direction is infinitely increased is effectively limited, the situation that the axial pressure of the main shaft is lower than 5000N is guaranteed, and the damage of a bearing on the main shaft is avoided.

Description

technical field [0001] The invention relates to the field of driving devices for electric vehicles, in particular to an inner rotor motor friction plate type self-adaptive automatic separation drive assembly of an electric motorcycle. Background technique [0002] At present, automobiles, motorcycles, and electric bicycles basically directly control the throttle or current to control the speed through the speed control handle or the accelerator pedal, or use the manual mechanical automatic transmission mechanism to realize the speed change. The operation of the handle or the accelerator pedal depends entirely on the operation of the driver, which often results in a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor and stalling. In motor vehicles, when the rider does not know the driving resistance, the speed change device is only operated and controlled based on experience, which inevitably has the following problems: 1. ...
