Title:
VEHICLE TORQUE LIMITER DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/164647
Kind Code:
A1
Abstract:
Provided is a vehicle torque limiter device that is provided between an electric motor and a driving wheel, wherein the limit torque can easily be secured. Because the frictional engaging element (98) of the torque limiter device (24) can be disposed towards that outer circumference up to a position in the radial direction that is adjacent to the rotor (74) (rotor core (78)) of the electric motor (M1), a large effective disc (102) radius r can be secured. Consequently, the necessary limit torque Tlm can be obtained without increasing the number of discs (102), increasing disc (102) thickness, etc. And since the frictional engaging element (98) is disposed on the inside of the coil end (76), the space formed inside the coil end (76) is used effectively and the length of the power transmission device (10) in the axial direction can be shortened as a result of the overlap of the frictional engaging element (98) and the coil end (76) in the radial direction.
