Power distributing mechanism

摘要

The present disclosure describes a power distributing mechanism for a vehicle including rear wheels as driving wheels and front wheels as driving and steering wheels, comprising a drive shaft for the rear wheels; a shaft for the front wheels coaxially adjacent to the shaft for the rear wheels; a driving rotator having outer teeth and connected to the shaft for the rear wheels; a driven rotator having outer teeth and axially slidably connected to the shaft for the front wheels; a forcing mechanism for elastically forcing the driven rotator toward the driving rotator; a cylindrical intermediate member disposed around both rotators and having inner teeth engageable with the outer teeth of the respective rotators with circumferential spaces therebetween; and a braking mechanism for applying a braking force to the rotating intermediate member; said both rotators being provided at the end surface portions projections for disengaging the driven rotator.
