To reduce resistance to movement, and hence fuel consumption, reduce tire wear and suspension, by lowering the current dynamic loads on them, steerable wheels automobil club italia have to roll in vertical planes parallel to the longitudinal axis of the vehicle. Important factor in increasing the stability of the vehicle is to stabilize the steering angle t. E. Their desire to come back after the turn of the straight movement of the car. Given these factors, the wheels of cars are set with corners toe, camber, longitudinal and transverse inclination of the axis, with the difference between the inner and outer corners of the steering wheel.
Camber angle - the angle between the planes wheels and a vertical plane parallel to the axis of the vehicle and is considered positive if the upper part of the wheel is rejected out of the vertical plane. It is necessary to provide a perpendicular arrangement of the wheels when the vehicle is loaded vehicle relative to the road surface in the presence of gaps in the joints and the deformation of parts of the front axle under the influence of masses of the front of the vehicle. When installing the wheel with the angle of the reaction force of the road is mainly transmitted to the inner wheel bearing performed usually larger automobil club italia than the outer, which unloads the outer wheel bearing, and thus reduces the shocks transmitted to the steering gear.
In transverse tilting axis to turn the wheel is always more difficult than to return it to its original position - move in a straight line. This is because when turning the front of the vehicle is raised by a small amount, and the driver applies a relatively large force to the steering wheel.
However, with the collapse of the wheel seek to roll away from the longitudinal axis of the vehicle in an arc around the point "O" automobil club italia is the intersection of the continuation of the wheel axis and the plane of the road. To eliminate this phenomenon wheel mounted with converging, vol. Ie. Not parallel but at some angle to the longitudinal axis of the vehicle.
Violation camber leads to unilateral wear of the tire tread. If the camber angle is more the norm, the outer side of the tread wear on the other hand, if it is less than the norm - the inside of the tread. In addition, a significant difference in the corners of the collapse of the right and left wheels cause to pull to one side of the wheel with a large collapse.
In the operation of vehicles camber angles of the steered wheels are changed due to wear of the front suspension joints, front hub bearing and deformation of the front suspension crossmember. Toe angle
Toe angle (the difference in distance between the inner surfaces of the front and rear parts of the front tires or the rear axle (B - A)) is required in order to ensure parallel rolling of the wheels, as when driving a car because of the wheels with the collapse occurs effort that promotes unfolding the wheels at an angle of from 0.5-1.0 vertical plane of the vehicle, which leads to rolling wheels divergent arcs. In addition, automobil club italia the angle of convergence prevents wheel slip when there is play in the joints of the steering tie rods, wheel bearings.
Toe angle is increased stepwise to form the tread wear sharp edges directed to the longitudinal axis of the vehicle (at an increased angle) or outside (at a reduced angle).
A characteristic feature of the suspension front wheel drive cars are close to zero or even negative values of excessive camber and toe. The location of the front wheels under such angles ensure their parallelism while driving when they passed the torque from the engine. The angle of the longitudinal axis tilt rotary rack
The longitudinal inclination of the wheel axis is set so that its pivot point with respect to the axis of rotation attributed back by a certain amount and the wheel always tends to occupy the original position, ie. Ie. Position of the vehicle when moving straight ahead. This value is the shoulder lateral force generated by the rotation, thereby creating a stabilizing moment that tends to rotate the wheel around the axis to return it to its original position. This provides better stability and stabilization of the steered wheels in the straight driving.
However, stabilization of the steered wheels depends on the elasticity of the tires. The more elastic tires, the more deformation and the moment automobil club italia tends to turn the wheel to the neutral position. The angle of inclination of the transverse axis of the strut
