IN-WHEEL MOTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240253448 titled 'IN-WHEEL MOTOR
The abstract describes an in-wheel motor with an oil pump system integrated into the motor cover. The pump chamber is closed off by a pump cover attached to the motor cover, with a pump shaft penetrating it. Inside the pump chamber, there is a drive gear attached to the pump shaft and a driven gear that meshes with the drive gear. The pump shaft is connected to the input shaft of the reduction gear, and the pump cover is bolted to the motor cover from the inside of the case, with a positioning structure for the pump shaft.
- Oil pump system integrated into the motor cover of the in-wheel motor.
- Pump chamber closed off by a pump cover attached to the motor cover.
- Drive gear and driven gear arranged inside the pump chamber for oil circulation.
- Pump shaft connected to the input shaft of the reduction gear for efficient operation.
- Pump cover bolted to the motor cover with a positioning structure for the pump shaft.
