  Hotchkiss Drive • Thistype of drive is commonly used on passenger cars and heavy commercial vehicles. • This arrangement (Fig) uses two rear leaf springs, which are longitudinally mounted, and are connected to the frame by a ‘fixed’ pivot at the front, and swinging shackles at the rear. • A universal joint is mounted at each end of the propeller shaft, with provision for accommodating change in shaft length due to the deflection of the springs. • This drive, therefore, incorporates an open propeller shaft with two universal joints and a slip joint.

  Torque tube Drive •This drive system is generally used in passenger cars and Heavy commercial vehicles. • Figure illustrates a layout using laminated springs, which are connected to the frame by a swinging shackle at each end. • A tubular member called torque-tube, encloses the propeller shaft and is bolted rigidly to the axle casing. • The torque-tube is positioned at the front by a ball and socket joint, which is located at the rear of the gearbox or cross-member of the frame. • A small-diameter propeller shaft is installed inside the torque tube and splined to the final-drive pinion. • A universal joint is installed in the centre of the ball joint to allow for angular deflections of the drive.
