Mechanical trail is certainly one of the most important variables in determining the handling characteristics of a bicycle. A trail of zero may give some advantages: [23] the influence of the position of the center of pressure of wind forces coming from the side is eliminated; the wheel flop effect (see below) is eliminated
Scrub radius is changed whenever there is a change in wheel offset. For example, when the wheels are pushed out from the body of the car the scrub radius becomes more positive. Older cars tended to have very close to zero scrub radius but often on the positive side, while newer cars with ABS tend to have a negative scrub radius (this is why ...
A wheel with too much negative offset will be closer to the edge of the fender. This can cause clearance issues between the tire and the fender. One that has too much positive offset will be closer to the suspension components and could cause the tire to rub on them. Wheel width, offset, and its accompanying tire size all determine how a ...
Track (measured between center line of wheels) In automobiles (and other wheeled vehicles which have two wheels on an axle), the axle track is the distance between the hub flanges on an axle. [1] Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. In the case of an axle with ...
As with the small multiple chart, each panel uses the same underlying two-dimensional space, but in this case that is a geographic space. Typically, the variables being mapped are of a similar type, such as types of agricultural products, so that the same strategy of map symbol can be used on each panel, enabling rapid comparison between the maps.
Values less than one, where the front wheel side slip is greater than the rear wheel side slip, are described as under-steering; equal to one as neutral steering; and greater than one as over-steering. Values less than zero, in which the front wheel must be turned opposite the direction of the curve due to much greater rear wheel side slip than ...
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. [1] Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country.
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]
