Abstract
The present disclosure provides a wet friction engaging device. The device includes a plate group engaged with two connecting members and including two groups of friction plates housed in a plate housing chamber and alternately arranged in an axial direction with surfaces facing each other. The plate group is switched between an engaged state in which the friction plates are in close contact with each other, and a disengaged state in which the friction plates are separable from each other. End plates at respective ends of the plate group are kept at a larger distance in the axial direction after a switch to the disengaged state than in the engaged state.
Claims7
A wet friction engaging device for switching transmission of power to be output to a rotary shaft, the device comprising:
- two connecting members, each having an opposed surface facing an opposed surface of the other connecting member in a radial direction with a plate housing chamber interposed therebetween, the chamber being supplied with lubricating oil;
- and
- a plate group engaged with the connecting members and including two groups of friction plates housed in the plate housing chamber and alternately arranged in an axial direction with surfaces facing each other, wherein
- the plate group is switched between
- an engaged state in which the friction plates are in close contact with each other upon application of a pressing force, and
- a disengaged state in which the friction plates are separable from each other upon release of the pressing force, and
- end plates at respective ends of the plate group are kept at a larger distance in the axial direction after a switch to the disengaged state than in the engaged state.
