Construction:-

This drive is invented by Albert Hotchkiss. In the Hotchkiss drive two universal joints are used one at front and second at rear end of propeller shaft. Slip joint is used to accommodate change in length of propeller shaft. Leaf spring is shacked at the rear and bracketed at front end. Leaf spring takes Weight of body, driving thrust, side thrust, torque reaction and braking thrust. In the Hotchkiss drive, splines eliminate thrust transmitted back to the driveshaft from the wheels, allowing simple rear-axle positioning using parallel leaf springs. Due to torque reaction leaf spring deflects. It is used in heavy duty vehicles like bus and trucks.
