In-wheel motor and wheel assembly with this in-wheel motor
First Claim
Patent Images
1. A motor comprising:
- a stator core;
a coil;
a rotor;
a motor case in which the stator core, the coil, and the rotor are housed; and
a substantially annular fluid carrying member which is provided on a coil end of the coil in the motor case and has an inlet hole that is communicated with a fluid supply source and a distribution hole that is communicated with a space inside the motor case, whereinthe fluid supply source is driven by rotational output of a rotating shaft of a counter gear which reduces a rate of rotational output of an output shaft of the motor and transmits a resultant rotational output to a wheel.

Abstract
A motor has a stator core, a coil, a rotor, and a motor case in which the stator core, the coil, and the rotor are housed. The motor is also provided with a fluid carrying member that is arranged around a coil end of the coil in the motor case and has an inlet hole that is communicated with a fluid supply source and a distribution hole that is communicated with a space inside the motor case.

2. An in-wheel motor structure, comprising:
-
a motor that drives a wheel, which is arranged within the wheel and has a stator core, a coil, a rotor, and a motor case in which the stator core, the coil, and the rotor are housed; an oil pump that is driven by rotational output of a rotating shaft of a counter gear which reduces a rate of rotational output of an output shaft of the motor and transmits a resultant rotational output to the wheel; and a substantially annular fluid carrying member which is provided on a coil end of the coil in the motor case and has an inlet hole that is communicated with the oil pump, and a distribution hole that is communicated with a space inside the motor case.

3. An in-wheel motor structure, comprising:
-
a motor that drives a wheel, which is arranged within the wheel and has a stator core, a coil, a rotor, and a motor case in which the stator core, the coil, and the rotor are housed; a counter gear which reduces a rate of rotational output of an output shaft of the motor and transmits a resultant rotational output to the wheel; a bearing that rotatably supports a rotating shaft of the counter gear; a fluid supply source that is driven by rotational output of the rotating shaft of the counter gear; and a substantially annular fluid carrying member which is provided on a coil end of the coil in the motor case and has an inlet hole that is communicated with the fluid supply source and a distribution hole that is communicated with the bearing.
