IN-WHEEL MOTOR DRIVE DEVICE |
| 摘要 |
An in-wheel motor drive device includes an electric motor to drive a wheel, a wheel support bearing assembly to support the wheel, and a speed reducer to reduce the rotation of the electric motor and then to transmit it to the wheel support bearing assembly, and a lubricant oil is supplied under pressure by an oil pump to the speed reducer to be lubricated. The use is made of a temperature detector to detect the temperature of the lubricant oil or the electric motor and an output limitter to limit the output of the electric motor in the event that the temperature detected by the temperature detector is not higher than a predetermined threshold value. |

1. An in-wheel motor drive device including an electric motor to drive a wheel, a wheel support bearing assembly to support the wheel, and a speed reducer to reduce the rotation of the electric motor and then to transmit it to the wheel support bearing assembly, the speed reducer being lubricated by a lubricant oil supplied under pressure by an oil pump, which in-wheel motor drive device comprises:
a temperature detector to detect the temperature of the lubricant oil or the temperature of the electric motor; and an output limitter to limit the output of the electric motor in the event that the temperature detected by the temperature detector attains a value not higher than a predetermined threshold value. |
