When was torsion bar suspension invented?
On 10 August 1931, Ferdinand Porsche applied for a patent for an invention that would have an impact on automotive manufacturing the world over: torsion bar suspension. Until that time, the usual chassis designs relied on the use of heavy, protruding leaf springs that still originated from carriage building.
Which is the best description of a torsion bar suspension?
A torsion bar suspension, also known as a torsion spring suspension or torsion beam suspension, is a general term for any vehicle suspension that uses a torsion bar as its main weight bearing spring.
When did Morris start using torsion bar suspension?
Post-war the use of torsion bar front suspension was a defining feature of British Morris cars, starting with the Morris Minor of 1948, its larger Morris Oxford MO counterpart and the upmarket Morris Six MS, plus the Wolseley -badged upmarket variants of the latter two models.
When did Farina start using torsion bar suspension?
The Oxford/Six platform was developed through several revised series which used Issigonis’ torsion bar system until 1959 when the new Farina Oxford was introduced using front suspension with coil springs, lower wishbones and lever arm dampers.
What was the first car to have a torsion bar?
An early application of a torsion bar in an American car was by Hudson Motor Car Company of Detroit who had introduced the innovative front Axle Flex suspension in 1934 Hudson and Terraplane cars and realized for 1935 that a transverse torsion bar linked to the rear axle was needed as an anti-roll bar to stabilize the cars.
Where is the torsion bar on a Honda Accord?
You can see the torsion bar under the front (sticking out past the right center of the front tire and extending back to its mount near the front door). The torsion bar suspension doesn’t have any coil springs between the front suspension arms. Instead it uses a torsion bar that is connected to the lower arm and runs parallel with the frame.

How does a torsion bar suspension system work?
It returns to its original position when the bump is passed and restores the car to its normal drive height. The resistance of the bar to twisting has the same effect as the spring used in more conventional suspension systems. A certain amount of load is permanently applied to the bar to maintain the car’s ride height.
