What does thrust angle mean?

What does thrust angle mean?

The thrust angle measures axle alignment by comparing the angle of the rear axle with the centerline of your vehicle. Looking at a car from above, you would draw the thrust line perpendicular to the rear axle. This identifies the direction in which the rear wheels want to roll.

How do you find the thrust angle?

To give an example, the distance between the mounting holes on the DA 100 is 2.75″. If you want a 2.5 degree right thrust angle, then: Extra Length = 2.75″ * tan(2.5) = 0.120″. The left side of the engine will need to be extended 0.120″ farther than the right to have a thrust angle of 2.5 degrees.

What should the thrust angle be?

Thrust Angle, also referred to as Thrust Line, is the angle of the centre line in relation to the rear axle or the theoretical rear axle. The centre line should be 90 degrees from the rear axle, which in turn means there is 0 degree thrust angle.

Which angle is called the thrust angle?

The thrust angle is the imaginary line that is 90 degrees from the rear axle center line. It compares the direction the axle is pointed to the center line of the vehicle.

What is a normal thrust angle?

The thrust angle is an imaginary line drawn perpendicular to the rear axle’s centerline. It compares the direction that the rear axle is aimed with the centerline of the vehicle. It also confirms if the rear axle is parallel to its front axle and that the wheelbase on both sides of the vehicle is the same.

What is a positive thrust angle?

The thrust angle is the difference between the geometric centerline and the thrust line, measured in increments of degrees. If the thrust angle aims to the right, this is called a positive thrust angle.

Can thrust angle be adjusted?

The thrust angle is the angle between where the rear are directed and the centerline of the vehicle. The only way to adjust the thrust angle is through adjustable rear CAs. Why are you concerned with it? It is usually zero, unless you want to preload the steering to one side as in oval racing.

Is thrust angle bad?

When the rear axle is not parallel to the front axle (or the car’s centerline) or if the rear wheel’s toe angle is wrong, a thrust angle is not straight ahead, causing off-center steering. It is going to cost more for a four-wheel alignment, but you will save at least that much in extended tire life.

What is setback angle?

Setback is a diagnostic angle. that measures the difference in distances between the centers of the front wheels. Differences in the setback angle can indicate damage in the frame or within components like control arms and bushings.

How do you change thrust angle?

First, the thrust angle could be generated by the angle of the axle or a misaligned rear suspension cradle that can change the toe angles. Also, a thrust angle can be generated by rear toe settings that are independent of the axle angle or implied axle angle.

Can thrust angle cause a pull?

A positive thrust angle will try to steer the vehicle to the left, while a negative thrust angle will try to steer the vehicle to the right. This will cause the driver to pull the steering wheel right or left to compensate.

What’s “thrust angle” wheel alignment mean?

A thrust angle alignment will compensate for the rear end pulling the car in one direction or another. Every car has a thrust angle, solid rear axle or independent. But with an independent rear suspension that has adjustments, you can compensate it, and set it to the centerline of the car.

What is the reason for the thrust angle?

In the case of a vehicle with a solid rear axle, a thrust angle is most likely to have been caused by an impact or collision. The rear axle and associated componentry were jarred by an impact that created the angle.

What is a thrust angle alignment?

A thrust angle alignment uses the rear wheels as a reference to align the front wheels. This type of alignment is used for those vehicles that have non-adjustable rear suspensions.

What is positive thrust angle?

Positive thrust angle means the thrust line is pointing to the right hand side of the vehicle. Negative thrust angle means the thrust line is pointing to the left hand side of the vehicle. If the thrust angle is out of specification, moving the axle to body relationship will change the thrust angle reading.
