Title:
MOTIVE POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/110168
Kind Code:
A1
Abstract:
This motive power transmission device (10) is provided with an annular armature (14) which is connected to a rotor (11) by the electromagnetic attraction of an electromagnet (12) when a current is being passed through the electromagnet, and which is separated from the rotor when the current is not being passed through the electromagnet. The armature has, formed thereon, an armature-side friction surface (140) which is in contact with a rotor-side friction surface (110) formed on the rotor, when the current is being passed through the electromagnet. Slit-like grooves (147, 147A, 147B, 147C) which extend towards the outer circumferential side from the inner circumferential side are formed in the armature-side friction surface. Furthermore, different materials (17, 18) from the material which forms the armature-side friction surface are disposed in the grooves.
