What is a strut suspension system?
A strut is a major structural part of a suspension. It takes the place of the upper control arm and upper ball joint used in conventional suspensions. Because of its design, a strut is lighter and takes up less space than the shock absorbers in conventional suspension systems. Struts perform two main jobs.
What is the main feature of MacPherson strut suspension?
A MacPherson strut uses a wishbone, or a substantial compression link stabilized by a secondary link, which provides a mounting point for the hub carrier or axle of the wheel. The lower arm system provides both lateral and longitudinal location of the wheel.
How do struts work?
Struts provide structural support by connecting the upper strut bearing to the lower ball joint. This allows the strut to move as the tire is turned. Your vehicle’s suspension is in charge of keeping your tires in contact with the road surface at all times. Struts are a dampening device for your vehicle.
Why are struts used?
The primary purpose of the struts is to support the weight of the vehicle while also absorbing surface impacts and ensuring a smooth ride.
Which is better shocks or struts?
Struts are designed to be much stronger than shocks since they are weight-bearing components. Additionally, they help dampen vehicle jolts and improve your vehicle’s steering and alignment.
What are the disadvantages of MacPherson strut?
Disadvantages. The MacPherson suspension has a lengthy vertical assembly to it. If you need to lower your vehicle for whatever reason, you could run into some problems there. Anyone driving a race car or sports car will not want this suspension because those types of cars are often lowered closer to the ground.
What is a MacPherson strut?
The MacPherson strut is a type of automotive suspension system that uses the top of a telescopic damper as the upper steering pivot. It is widely used in the front suspension of modern vehicles, and is named for American automotive engineer Earle S. MacPherson, who invented and developed the design.
What is the difference between Ford’s RevoKnuckle front suspension and GM HiPER struts?
Ford’s RevoKnuckle front suspension weighs 26 pounds more than conventional struts. The GM weight gain is slightly less. Ford engineered RevoKnuckle to optimize the performance of its too-cool-for-the-U.S., 300-hp Focus RS. GM developed HiPer Struts for the Buick LaCrosse CXS and Regal GS.
Who invented the strut suspension?
Patents were filed in 1947 ( U.S. Patent 2,624,592 for GM) and in 1949 ( U.S. Patent 2,660,449 for Ford), the 1949 patent citing designs by Guido Fornaca of FIAT in the mid-1920s. The strut suspension of the pre-war Stout Scarab could have been an influence, and long-travel struts in aircraft landing gear were well known by that time.
What are struts in a car chassis?
As components of an automobile chassis, struts can be passive braces to reinforce the chassis and/or body, or active components of the suspension. An example of an active unit would be a coilover design in an automotive suspension.
