Power Transmission Mechanism for Electric Vehicles

Abstract

The invention belongs to the field of transmission mechanisms for electric carriers, in particular to a power transfer mechanism of an electric carrier, which uses single rotating power source for respectively driving two planetary reduction modules and two output shafts to perform the differential output. The power transfer mechanism of the electric carrier comprises a shell, a motor stator, a first output shaft, a motor rotor, a first planetary reduction module, a second output shaft and a second planetary reduction module, wherein the motor stator, the motor rotor, the first planetary reduction module and the second planetary reduction module are respectively accommodated in the shell; the first planetary reduction module is connected with the first output shaft; the second planetary reduction module is connected with the second output shaft; and the first output shaft and the second output shaft are connected by a movable positioning mechanism, so that the first output shaft and the second output shaft respectively perform the differential output by the first planetary reduction module and the second planetary reduction module to achieve a differential effect of double output power sources by single power source.

Description

technical field [0001] The invention belongs to the field of transmission mechanisms used by electric vehicles, and specifically relates to a power transmission mechanism for electric vehicles that utilizes a single rotating power source to respectively drive two planetary reduction modules and two output shafts for differential output. Background technique [0002] Generally, electric vehicles such as electric scooters, factory trucks, golf carts, electric ATVs, etc., because the load is low and does not require fast speeds, and does not need to use fossil fuel engine structures, most of them use electric vehicles. The motor is used as a rotating power source, which is driven by the electric power of the battery, so it will not cause air pollution. [0003] However, most of the electric motors used in electric vehicles adopt high-speed design, and with the appropriate power transmission mechanism, the high-speed power of the electric motor can be converted into high-torque ...

Problems solved by technology

[0005] However, after analyzing the structure of the new patent, the applicant in this case believes that it has many unenforceable deficiencies

Among them, the most important point is that the two output shafts are independent and not connected, which makes it difficult for the first planetary gear module and the second planetary gear module to move smoothly when rotating, and it is easy to be biased and cause the output shaft to be stuck or broken , in this way, it is easy to reduce the deceleration effect or malfunction, so it is necessary to improve
