Problems solved by technology

In the limited space inside the rim, the motor, speed change / reduction mechanism, and brake are integrated. At the same time, heat dissipation and lubrication, as well as the suspension connection between the electric drive wheel and the car body, are also considered. The selection of the overall scheme of the hub motor drive is directly determined. It affects the subsequent implementation of each subsystem component, and also affects the performance, reliability and manufacturing cost of the system

Abstract

The invention belongs to the technical field of mechanical-electrical integration transmission, and particularly relates to a hub motor drive device with a planetary transmission device. Compared with the prior art, a drive motor, a variable speed reduction mechanism and a brake mechanism are integrated in a rim, through the stepless speed adjusting function of the motor, a vehicle has the good dynamic property, switching of the low-speed gear and the high-speed gear can be achieved through operation of an electromagnetic clutch for a sliding sleeve, friction losses are reduced, and the transmission efficiency is improved; the drive motor, the planetary transmission mechanism, the brake mechanism and other structures are designed in an integrated manner, on one hand, supporting parts can be shared, the size is reduced, and on the other hand, whole dismounting and maintaining are facilitated.

Description

technical field [0001] The invention belongs to the technical field of electromechanical compound transmission, and in particular relates to a hub motor driving device with a planetary speed change mechanism. Background technique [0002] Under the background of the new military revolution, the idea of ​​"lighter, more maneuverable, and more flexible" army equipment has become the mainstream. Wheeled armored vehicles with faster response and deployment speed will play a pivotal role in the future urban combat, peacekeeping and other rapid mobile operations and more and more low-intensity operations that the Army will deal with. High passability is another key technical feature of the new generation of wheeled chariots. With the increase in the demand for mobility in all areas, especially the combat requirements on plateaus, mountains, and platforms, the demand for high passability of wheeled chariots has increased significantly. The technological innovations of various new ...
