investigation of the steering geometry according to Ackermann
- When it comes to steering, the entire vehicle’s wheel should be exactly on a circular path.
- To achieve this, the extensions of all the axles must intersect at the centre of the circle (Ackermann’s steering principle).
- This requires that the wheel inside of the curve drives more than the wheel outside of the circle.
- This is approximately achieved with a steering trapezoid, comprising an axle, a track rod and two track-rod arms on the wheels.
- The KI 160unit can be used to study a steering trapezoid.
- The experimental unit comprises two track rods with drag link, two track-rod arms and two steering pins, where, in theory, the wheels are attached.
- The length of the axis corresponds to the distance between the steering pins.
The lengths of the two track rods are independently adjustable.
- To set the zero position of the steering angle, the mechanism is fixed via a lock on the drag link.
- The steering angle on the inside wheel is set; the angle of the outside wheel changes according to the geometry and is read.
- The difference between the two angles is the lead angle or relative steering angle.
- The difference between the calculated and measured steering angles is the steering error.
- Disadvantages of an incorrectly set track rod can be demonstrated.
- The elements are mounted on a base plate, which can also be mounted on a wall.
