Super Torque Double Helix Double Transcendence Integrated Intelligent Adaptive Electric Drive Rear Drive System

Abstract

The invention discloses a super-torque double-helix double-override integrated intelligent adaptive electric drive rear drive system, which includes a motor, a high-speed gear transmission mechanism, a low-speed gear transmission mechanism and a main shaft for outputting power. The motor includes a stator and a rotor. And the motor shaft assembly driven by the rotor. With the above scheme, the space inside the motor is fully utilized, and some parts of the transmission mechanism can be installed inside the motor. Not only is the transmission line short, the transmission efficiency is high, but it is also conducive to the layout of the power mechanism and reduces the impact on the dynamic balance of the wheels; Compared with the traditional single-row overrunning clutch, the overrunning clutch doubles the load-bearing capacity and breaks through the load limit of the traditional overrunning clutch; thus, it can adapt to the change of driving resistance and automatically change gears without cutting off the driving force. , make the motor always on the high-efficiency platform as much as possible, greatly increasing the range of high-efficiency operation of the motor.

Problems solved by technology

At present, the electric drive systems of automobiles, motorcycles and tricycles powered by pure electricity are composed of two independent parts, the motor and the reduction box (gearbox or transmission box). Not only the transmission efficiency is not high enough, but also the layout of the mechanism is affected.

[0003] Due to the limitations of its transmission structure, the existing electric vehicle is completely controlled by the driver based on experience when the driving resistance cannot be accurately known during the driving process. The driving conditions do not match, causing the motor to stall

Especially when the vehicle is under low-speed and heavy-load conditions such as starting, climbing, and headwind, the motor often needs to work at low efficiency, low speed, and high torque, which is likely to cause accidental damage to the motor and increase maintenance and replacement costs. directly affect the battery life

For models with high economic requirements such as electric logistics vehicles, the traditional variable speed transmission structure obviously cannot better meet their use requirements

[0004] Moreover, the traditional roller overrunning clutch has limited load capacity, and the only way to increase the load capacity is to increase the size of the outer ring, inner wheel and rolling body, but the inner wheel and rolling body cannot be infinitely extended, especially the thinnest If the roller is too long, not only is it prone to uneven force, it may cause breakage, and it is difficult to guarantee the machining accuracy, and it is prone to poor meshing, which makes production difficult and the yield rate is low. At the same time, the requirements for materials are extremely high. , high production costs

Therefore, the existing self-adaptive automatic transmission device cannot withstand super large loads, the manufacturing cost remains high, and the reliability is insufficient.
