The essential problem is keeping the differential from rotating during acceleration and braking. The torque tube solves that problem by coupling the differential housing to the transmission housing and, therefore, propels the car forward by pushing up on the engine/transmission and then through the engine mounts to the car frame, with the ...
A Panhard rod (also called Panhard bar, track bar, or track rod) is a suspension link that provides lateral location of the axle. [1] Originally invented by the Panhard automobile company of France in the early twentieth century, this device has been widely used ever since.
The most famous American passenger car application of the torsion bar, was the Chrysler system used beginning with all Chrysler products starting with the 1957 model year in cars such as the Imperial Crown series, Chrysler Windsor, DeSoto Firedome, Dodge Coronet and Plymouth Belevedere although Chrysler's "Torsion-Air" suspension was only for ...
The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
The model E had been developed by 1922; this could be said to be the "classic" Doble, of which the most examples have survived. The initial monotube boiler design was perfected into the "American" type. This produced steam at a pressure of 750 psi (52 bar) and a temperature of 750 °F (400 °C). The tubing was formed from seamless cold-drawn ...
In 1920, Leyland Motors used torsion bars in a suspension system. In 1922, independent front suspension was pioneered on Lancia Lambda, and became more common in mass market cars from 1932. [8] Today, most cars have independent suspension on all four wheels. The part on which pre-1950 springs were supported is called a dumb iron.
It is the simplest damper and one of the most efficient. Ride height correction (self leveling) is achieved by height corrector valves connected to the anti-roll bar, front and rear. When the car is too low, the height corrector valve opens to allow more fluid into the suspension cylinder (e.g., the car is loaded).
Traction can also refer to the maximum tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the coefficient of traction (similar to coefficient of friction).
