ABSTRACT:
A transmission apparatus includes a rotatable drive shaft having a first a second end, the second end of the drive shaft defining a taper and a first portion of a dogtooth device. A rotatable driven shaft has a first and a second extremity, the driven shaft being selectively driven by the drive shaft, the driven shaft defining a spline. A slider drivingly cooperates with the spline, the slider being slidably secured to the driven shaft. A second portion of the dogtooth device is secured to the slider such that selective engagement of the first and second portions of the dogtooth device is permitted. A synchro ring defines a tapered bore, the ring being anchored within the slider such that when the slider is moved towards the taper of the drive shaft, the tapered bore of the ring cooperates with the taper of the drive shaft so that the ring and the slider anchored thereto are rotated and so that the first and second portions of the dogtooth device engage such that the driven shaft is driven by the drive shaft.
