Front suspension of a race car — the caster angle is formed by the line between upper and lower ball joint An example of a chopper with a raked fork at an extreme caster angle. The caster angle [1] or castor angle [2] is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car, motorcycle, bicycle ...
This can be contrasted with steer, which is the antisymmetric angle, i.e. both wheels point to the left or right, in parallel (roughly). Negative toe, or toe out, is the front of the wheel pointing away from the centreline of the vehicle. Positive toe, or toe in, is the front of the wheel pointing towards the centreline of the vehicle. [2]
Camber is the angle which the vertical axis of the wheel makes with the vertical axis of the vehicle. This angle is very important for the cornering performance of the vehicles. Generally, a Camber around 0.5-2 degrees is given on the vehicles. Depending upon wheel orientation, Camber can be of three types. 1. Positive Camber
The 1960 Milliken MX1 Camber Car has a large negative camber. Camber angle is one of the angles made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of a wheel and the vertical axis of the vehicle when viewed from the front or rear.
Zero scrub radius (top) positive scrub radius (center) negative scrub radius (bottom) In an automobile's suspension system, the scrub radius is the distance in front view between the king pin axis and the center of the contact patch of the wheel, where both would theoretically touch the road. It can be positive, negative or zero.
In motorcycles, the steering axis angle is measured from the vertical and called the caster angle, rake angle, or just rake; [5] a 0° rake is therefore vertical. For example, Moto Guzzi [6] offers: a 2007 Breva V 1100 with a rake of 25°30′ (25.5 degrees) a 2007 Nevada Classic 750 with a rake of 27.5°
The angle between the plane defined by the circumference of the wheels and the vertical axis of the body or chassis of a vehicle, as viewed from the front or rear of the vehicle. If the top of the wheel is tilted outward, away from the body, the wheel is said to have positive camber ; if the top is tilted inward, towards the body, it is said to ...
Ackermann geometry. The Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.
