Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2017026050
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power transmission device which facilitates coupling of a coupling part and reduces noises in the coupling part in a configuration for coupling an internal combustion engine and a rotor.SOLUTION: A power transmission device 100 comprises: a crankshaft 1b of an internal combustion engine 1; a coupling part 3; an outer rotor 12 which is connected to the crankshaft 1b via the coupling part 3; and an inner rotor 11 which is connected to a vehicle drive mechanism 29 and rotatable relatively to the outer rotor 12. The coupling part 3 includes: a first torque transmission member 3a which is integrally provided in the crankshaft 1b; and a second torque transmission member 3b which is integrally provided in the outer rotor 12. A first projection 3c and a first recess 3d of the first torque transmission member 3a and a second projection 3e and a second recess 3f of the second transmission member 3b are shaped to be tapered oppositely to each other, and fitted in such a manner that a rotational driving force can be transmitted. The second torque transmission member 3b is elastically bent in such a manner that an elastic pressure acts upon the first torque transmission member 3a.SELECTED DRAWING: Figure 3
