Device and method for connecting hollow shaft motor and planet gear

Abstract

The invention provides a device and a method for connecting a hollow shaft motor and a planet gear, wherein the device is composed of a gear ring, a planet carrier, a planet wheel, a central wheel, a connector, a hollow shaft motor, a hollow shaft and a centric shaft; the central wheel is connected to the hollow shaft driven by the hollow shaft motor; one side of the planet carrier is connected to the centric shaft while the other side can be connected or separated from the hollow shaft through the connector. The connector can be a slider of a double position spline shaft coupling preferably. The device and method for connecting a hollow shaft motor and a planet gear provided by the invention have the advantages that the device can be applied to a hybrid electric vehicle and other new energy source vehicles, the coupling input and output of more than two powers can be carried out, the structure is simple, the weight is relatively low, the function is complete, and the price is low.

Description

technical field [0001] The invention relates to a device and method for connecting a hollow shaft motor to a planetary gear, in particular to a device and a method for connecting a hollow shaft motor to a planetary gear that can be used in new energy vehicles. Background technique [0002] Hybrid vehicles and other new energy vehicles generally mix the two powers of the engine and the motor, couple the speed and torque according to a certain control strategy, and finally output them to the wheels. Insufficient, so that the engine works in a better efficiency range, and at the same time, the braking energy can be recovered, so energy saving and emission reduction. [0003] Existing hybrid power coupling methods generally use mechanical or electromagnetic clutch devices, planetary gears and other transmission devices to connect and combine the engine and the motor externally, and there are also some forms that are realized by the power coupling between the motor and the engine...

AI Technical Summary

Problems solved by technology

[0003] Existing hybrid power coupling methods generally use mechanical or electromagnetic clutch devices, planetary gears and other transmission devices to connect and combine the engine and the motor externally, and there are also some forms that are realized by the power coupling between the motor and the engine using a hollow shaft, but These coupling methods are either simple and extensive, with simple functions, or become complicated in pursuit of more variable combined output methods, with large volume and weight, and high cost

[0004] There is still no simpler and more effective device and method for connecting the hollow shaft motor with the planetary gear in the market.
