The Christie suspension is a suspension system developed by American engineer J. Walter Christie for his tank designs. It allowed considerably longer movement than conventional leaf spring systems then in common use, which allowed his tanks to have considerably greater cross-country speed.
The moving parts of the system, e.g., suspension strut or steering ram, are sealed by contact seals between the cylinder and piston for tightness under pressure. The other plastic/rubber parts are return tubes from valves such as the brake control or height corrector valves, also catching seeping fluid around the suspension push-rods.
Automotive suspension design is an aspect of automotive engineering, concerned with designing the suspension for cars and trucks. Suspension design for other vehicles is similar, though the process may not be as well established. The process entails Selecting appropriate vehicle level targets; Selecting a system architecture

John Walter Christie (May 6, 1865 – January 11, 1944) was an American engineer and inventor. [1] He is known best for developing the Christie suspension system used for several World War II-era tank designs, most notably the Soviet BT and T-34 [3] tanks series, and the United Kingdom Covenanter and Crusader Cruiser tanks, as well as the Comet heavy cruiser tank.
