This drive is generally used in light commercial vehicles and cars. Generally, the torque tube drive provides a smoother ride compared to the Hotchkiss drive. It consists of a tubular member which encloses the propeller shaft, bolted rigidly to the axle casing. The front end of the torque tube drive is located in a ball and socket joint, which is located at the end of the gear box output shaft. Torque tube takes only torque reaction and driving torque. Spring takes only side thrust besides supporting the body weight. Forward thrust can be transferred from gear box mounting to the frame (Figure 7.2).

The bellows unit is a liquid-filled, sealed element, and the bellows assembly is temperature compensated. The motion of the bellows, due to differential pressure changes, is translated into a rotary shaft motion by means of a lever and torque tube. The torque tube eliminates the need of a shaft seal.

To appreciate why the full torque-tube drive has long been obsolete and the semi version has received limited acceptance, it is necessary to make a few general comparisons not only between these two forms of torque-tube drive, but also to relate them to the rival Hotchkiss drive system.

A leaf spring undergoes various loads during the running condition, but these loads depend on the drive used for the transfer of torque from the transmission to the axles. There are two different types of drives commonly used in commercial vehicles, namely Hotchkiss drive and Torque tube drive. Among these drives, Hotchkiss drive is used in the heavy-duty vehicles since in this type of drive, the propeller shaft is coupled to the differential with the help of universal joint, which ensures that not much drive thrust is experienced by the differential and impacts of most of the loads like drive torque, brake torque acts on the leaf spring. Therefore, designing of leaf spring considering these factors is very necessary for failure analysis. This arrangement 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 exposed or ‘open’ type 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.
