Abstract
A clutch mechanism for the drive train of a four-wheel drive vehicle for controlling the application of braking power between the front and rear wheels as applied through the drive train. A driving shaft is connected to a driven shaft through a roller clutch assembly and the driven shaft is coupled to a wheel set equipped with anti-lock brakes. The driving shaft has a drive cam race and a driven shaft has a cylindrical race. A cage carries the clutch rollers and is provided with drag shoes biased against a fixed drag ring. The rollers captured by the cage continuously drag against the rotative urging of the driving shaft whereby the rollers engage the cylindrical race with the driving shaft inducing driving rotation of the driven shaft, and disengage with the driving shaft inducing braking rotation of the driven shaft.
