3D four-wheel aligner

The 3D positioning device adopts the principles of perspective and computer information processing technology. Four target reflectors are installed on four wheels, and the wheels are rolled. The camera continuously captures the geometric shapes on the target reflectors. The computer analyzes and calculates the changes in the geometric shapes to obtain positioning parameters, which are then displayed on the display screen. It is currently a relatively advanced measurement method. Its advantages are: ① higher accuracy, reaching 0.1mm/0.01 °; ② Powerful, in addition to measuring traditional parameters, it can also measure wheel deviation distance parameters, achieving single wheel positioning, toe lock measurement, air suspension vehicle positioning, etc.; ③ Easy to operate, not affected by platform levelness or body inclination, all parameter measurements can be completed by simply pushing the car or rolling the wheels; ④ No need for regular calibration, can be moved and used freely; ⑤ Low failure rate, the target reflector has no electronic components, no batteries, no data transmission, and only serves as image reflection; ⑥ Computers are mostly high-end brand configurations, suitable for ultra large data processing and stable performance.

The difference between a double-column lift and a dragon gate lift

There are big structural differences between the double-column lift and the dragon gate lift.The double-column lift is achieved by lifting the vehicle through two parallel columns.The gantry lift uses the upper and lower brake structure to realize the vehicle's rise and fall.

How many liters of hydraulic oil is needed for the lift

The amount of hydraulic oil for a lift depends on the model and capacity of the lift.Generally speaking,the amount of hydraulic oil for a small lift is about 3L,and the amount of hydraulic oil for a large lift is more than 20L.When adding hydraulic oil,you need to level the lift and add the correct amount of hydraulic oil according to the instructions of the lift.Do not add too much or too little.

Basic knowledge of 3D four-wheel aligner

Novices will find in the 3D four-wheel aligner test that the test data of various vehicles are far from the standard data,and they often don't know where to start when debugging.In particular,it is pointed out here that the standard is for new cars,and the standard is only for reference data for old cars.For example,when adjusting the front beam,for old cars with independent suspension of the front wheels,the front beam value of the front-wheel drive vehicle can only be adjusted to be less than the standard,and the front beam value of the rear-wheel drive vehicle can only be adjusted to be greater than the standard.Since there is generally no turntable for rear wheel debugging,the elastic effect should be considered when debugging the front beam of the rear wheel.

Daily maintenance of 3D four-wheel aligner

The handling stability of a car refers to the fact that the vehicle can travel in the direction specified by the driver through the steering system without the driver feeling nervous or tired, and when encountering external disturbances, the vehicle can resist disturbances and maintain smooth driving.The handling stability of the vehicle not only affects the convenience of the vehicle, but also the main factor that determines the safety of the vehicle at high speed. In order for the vehicle to achieve good handling stability, the reasonable design of the suspension, chassis and steering system and the setting of related data have become important conditions. The main data that affect the suspension and steering system include the camber angle of the wheel kingpin, the rear camber angle of the kingpin, the front camber angle and the front beam angle, the rear camber angle and the rear beam angle. Once these data change, they will be reflected in the driving state of the vehicle, such as steering wheel shake, increased steering force, incorrect steering wheel position, vehicle deviation, tire wear, etc. In view of this situation, the necessary adjustments to the data are required to correct the handling stability of the vehicle.This operation is professionally called four-wheel positioning, including front wheel positioning and rear wheel positioning.
