What is the purpose of trailing arm?

Trailing arms function as a pivot point perpendicular to the length of the vehicle. They also prevent the rear axle or rear spindle from moving forward or rearward during operation of the vehicle.

What is the main disadvantage of the swing arm suspension geometry?

3 Long swing arm suspension (Figure 10.19) The inherent disadvantage of the short swing arm suspension is that there is too much camber change with body roll and there is a tendency for the axle arms to jack the body up when cornering.

What type of suspension is a trailing arm?

A trailing-arm suspension, sometimes referred as trailing-link is a vehicle suspension design in which one or more arms (or “links”) are connected between (and perpendicular to and forward of) the axle and a pivot point (located on the chassis of a motor vehicle).

What are the advantages of trailing arm suspension?

A semi-trailing arm suspension allows you to place the roll centre wherever you desire as well as placing the instant centre in a desirable place. This will allow you to have camber change and somewhat tune the camber curve based on analysis. Both the camber change and tire scrub will stay constant.

How does a trailing arm suspension work?

The trailing arm acts as a rocker member of the suspension where in it is mounted to the chassis by pivot points. The spring and damper are attached to the arm by pivot points, to get required relative motion during moment of the arm.

What is short swing arm suspension?

The motorcycle rear suspension mainly consists of a telescopic shock-absorber on each side and swingarms. In some countries, manufacturers call a swingarm a “swinging arm”. However, its original name was swing fork or pivoted fork. It allows the suspension to absorb the road shocks.

How many trailing arms does a car have?

Many cars have at least four control arms: One for each wheel. Some cars have upper and lower control arms. Made from a strong and highly-durable metal, the rear control arms, which are sometimes referred to as trailing arms, connect to the frame at one end.

Can you drive a car with a broken trailing arm?

Cracked or bent trailing arms should be replaced. Driving with a cracked trailing arm could lead to separation of that side of the axle, and it’s only a matter of time before further damage occurs.

What is the difference between trailing arm and semi trailing arm?

Trailing arm suspension (the upper picture) employs two trailing arms which are pivoted to the car body at the arm’s front edge. Semi-trailing arm suspension (the lower picture) has the trailing arm pivoted at inclined angles – about 50 to 70 degrees. Otherwise are the same as trailing arm suspension.

How long do trailing arms last?

Over time, the control arm assembly can become worn or bent. These assemblies normally wear out between 90,000 and 100,000 miles. They can wear out faster if you go over a large pothole or are involved in a car accident. Various parts of the assembly may wear out as well, such as the bushings or ball joints.

What is a semi-trailing arm suspension?

A semi-trailing arm suspension is a supple independent rear suspension system for automobiles where each wheel hub is located only by a large, roughly triangular arm that pivots at two points.

What is a twist-beam rear suspension?

A twist-beam rear suspension is very similar except that the arms are connected by a beam, used to locate the wheels and which twists and has an anti-roll effect. Some aircraft also use trailing arms in their landing gear, with oleo struts for shock absorption.

What are the advantages of rear independent rear suspension?

Compared with more refined rear independent rear suspension designs, such as double wishbone suspension or multi-link suspension, its advantages are lower cost and complexity (just two bushings per side!) and more compactness.

Why do some aircraft have trailing arms in their landing gear?

Some aircraft also use trailing arms in their landing gear, with oleo struts for shock absorption. A trailing arm landing gear results in smoother landings and a better ride when taxiing compared to other types of landing gear.
