Abstract
A power transmission system and an attenuation mechanism are disclosed. A power transmission system includes an electric motor, a drive wheel, a transmission shaft and an attenuation mechanism. The transmission shaft transmits a torque between the electric motor and the drive wheel. The attenuation mechanism is attached to the transmission shaft. The attenuation mechanism includes a support member and an inertia member. The support member is attached to the transmission shaft. The inertia member is disposed to be rotatable relative to the transmission shaft. The inertia member is engaged with the support member by friction.
Claims15
A power transmission system comprising:
- an electric motor;
- a drive wheel;
- a transmission shaft configured to transmit a torque between the electric motor and the drive wheel;
- and
- an attenuation mechanism attached to the transmission shaft, wherein
- the attenuation mechanism includes
- a support member attached to the transmission shaft, and
- an inertia member disposed to be rotatable relative to the transmission shaft, the inertia member engaged with the support member to attenuate torque fluctuations due to friction alone.
An attenuation mechanism for attachment to a transmission shaft transmitting a torque between an electric motor and a drive wheel, the attenuation mechanism comprising:
- a support member configured to be attached to the transmission shaft;
- and
- an inertia member disposed to be rotatable relative to the transmission shaft, the inertia member engaged with the support member to attenuate torque fluctuations due to friction alone.
A power transmission system comprising:
- an electric motor;
- a drive wheel;
- a transmission shaft configured to transmit a torque between the electric motor and the drive wheel;
- and
- an attenuation mechanism attached to the transmission shaft, the attenuation mechanism including
- a support member attached to the transmission shaft, and
- an inertia member disposed to be rotatable relative to the transmission shaft, the inertia member engaged with the support member by friction;
- wherein the attenuation mechanism is disposed separately from a torque transmission path between the electric motor and the drive wheel.
