How to adjust the tilt angle of four-wheel alignment

Question 1: How to adjust the camber angle of four-wheel alignment? The greater the camber angle, the more serious the eccentric wear of the tire. Moreover, if the inclination angle is too large, the friction area between the tire and the ground will decrease when the vehicle runs in a straight line, which will lead to the decrease of the longitudinal grip of the tire, acceleration and weakening of the braking force. However, if the degree of negative camber is appropriate, the vehicle will roll when turning, and the camber of the wheel will become positive camber, thus increasing the contact area of the tire, thus increasing the adhesion of the tire when turning and improving the tracking performance of the vehicle when turning (if the negative camber is 1-2 degrees, it is still acceptable).

Four-wheel alignment: Four-wheel alignment is an adjustment according to the four-wheel parameters of the vehicle to ensure good driving performance and certain reliability of the vehicle. The steering wheel, steering knuckle and front axle of an automobile have a certain relative position, which is called steering wheel positioning, also known as front wheel positioning. Front wheel alignment includes four contents: caster angle, caster angle, camber angle and toe-in of front wheel.

Question 2: What kind of car inclination angle can be adjusted by four-wheel alignment? What cannot be adjusted? Four-wheel alignment-caster angle: When the wheel is viewed from the side, the steering kingpin (the rotation center when the wheel rotates) falls backwards, which is called caster angle. After the caster angle of the kingpin is set, the distance between the center line grounding point of the kingpin and the ground projection point of the wheel center (called kingpin pitch, which is the same as the principle that the front wheel fork beam of the bicycle leans backwards) is generated, so that the wheel grounding point is located at the back end of the extension line of the steering kingpin, and the wheel is pulled backwards through rolling resistance during driving, so that the wheel direction naturally faces the driving direction. Setting a large caster angle of the kingpin can improve the straight running performance, and at the same time, the pitch of the kingpin also increases. Excessive pitch of the kingpin will make the steering wheel heavy, and the front and rear bumps of the wheels will be aggravated by road interference.

Four-wheel alignment-kingpin inclination: when the tire is viewed from the front and rear direction, the kingpin axis is inclined to the inside of the car body, and this angle is called kingpin inclination. When the wheel rotates around the kingpin, the lowest point of the wheel will fall below the road surface, but in fact, the lower edge of the wheel cannot fall below the road surface, but the steering wheel and the whole front of the car will be raised by a corresponding height, so that the gravity of the car itself will restore the steering wheel to its original middle position, so the steering wheel can be easily reset. In addition, the inclination angle of the kingpin also reduces the distance from the intersection point between the kingpin axis and the road surface to the intersection point between the wheel center plane and the ground, thus reducing the force exerted by the driver on the steering wheel during steering, making the steering operation lighter and reducing the impact force transmitted from the steering wheel to the steering wheel. However, the inclination angle of the kingpin should not be too large, otherwise the tire wear will be accelerated.

Four-wheel alignment-camber angle of front wheel: When looking at the wheel from the front and rear direction, the tire is not installed vertically, but slightly inclined in the shape of Zhang Kaicheng, which is called negative camber angle, and when it is opened in the opposite direction, it is called positive camber angle. In the heyday when diagonal tires were used, the camber angle was set to be relatively large because the tires touched the ground obliquely, which was convenient for the operation of the steering wheel. Nowadays, cars generally set the camber angle very small, close to vertical. Flat radial tires for automobiles are becoming more and more popular. Due to the characteristics of radial tire (high tread rigidity and wide tread), if camber is set, the tire will be eccentric and the tire friction will be reduced. Due to the continuous use of power steering mechanism, camber angle is also shrinking. However, setting a small camber angle can exert appropriate lateral thrust on the wheel bearings on the axle.

Four-wheel alignment-front wheel toe-in: toes are inward, so-called "inner splayed feet" means that the left and right front wheels are inward respectively. The purpose of adopting this structure is to correct the outward rotation of the wheel caused by the camber angle of the front wheel. As mentioned earlier, steering wheel operation becomes easy due to camber angle. On the other hand, because the wheels are inclined, the left and right front wheels rotate outward respectively. In order to correct this problem, if the left and right wheels have inward angles, plus or MINUS zero, the left and right wheels can keep moving in a straight line and reduce tire wear.

Question 3: Four-wheel alignment, how to adjust the tilt angle of Honda Accord? The rear wheel inclination angle of imported Honda Accord should be non-adjustable. If it is out of range, the corresponding deformed parts, such as the rear axle, the rear claw shaft and the rear swing arm, should be replaced.

Accord is a practitioner of Honda's innovative spirit and global leading technology, with a global history of 38 years. 20/KLOC-In September, 2003, China's first car equipped with Honda's "Earth Dream Technology"-Guangqi Honda's ninth-generation Accord was unveiled.

Question 4: how to adjust the camber angle with eccentric screws for automobile four-wheel alignment, with the abdomen of the big screw facing inward,

The camber angle is small, and the abdomen of the screw is inward.

Question 5: How to adjust the tilt angle of Bora by four-wheel alignment? Is it because the car can't be adjusted? Is there something wrong with the car hitting the swing arm? Ask the car master. 4S shop professional technician, 10 minutes to solve.

Question 6: How to adjust the inside and outside inclination of the four-wheel alignment kingpin? Hello, the angle must be detected by a four-wheel locator. Different models have different adjustment positions, some adjust the shock absorption fixing place, and some adjust the lower arm.

Question 7: How to clamp the four-wheel alignment angle ruler to the steel ring? If there is something wrong with the car observed during calibration, ask the car master. 4S shop professional technician, 10 minutes to solve.

Question 8: How to adjust the tilt angle of Jetta's four-wheel alignment? Only the front wheels can be adjusted at will. The rear wheel deviation is not too big, so special gaskets are needed, which cannot be directly adjusted.

The data of the front wheel is -30' 20', and the data of the front chicken is 0.5'

Question 9: Why can't the camber be adjusted when the car is doing four-wheel alignment? If the error is small, it can be adjusted, and if it is large, it may be damping deformation.

Question 10: Which wheel does the adjustment sequence of four-wheel alignment start from? Generally speaking, what are the tilt angles? First, start with the rear wheel, the rear wheel camber, the rear wheel toe angle, then the front wheel caster and the front wheel camber, and finally the front wheel toe angle. Angle, according to the data adjustment.
