How to perform four-wheel alignment on a cutting car

When cutting a car, you only need to do the alignment of the front wheels. The two rear wheels are fixed, so as long as they are not broken, they will not be misaligned. The front wheel actually just adjusts the toe, and the values ​​are both plus and minus zero. I just drew a picture, which shows the specific locations for adjusting the steering wheel angle and toe-in. When searching, you can start from the rocker arm of the steering gear. The one connected to it is the direction rod. There is an adjustment mechanism on it, which is a cylinder with positive and negative threads. Twist it to extend the direction rod. Longer or shorter, it also controls the twisting angle of the rocker arm on the steering gear and the angle of the front wheel. Remember, this thing is used to control the correct position of the steering wheel. At the end of the steering rod close to the front wheel on the passenger side, there is a ball head. The ball head is connected to a cross bar and the other front wheel. This is the steering tie rod, which indirectly transmits the power of the steering wheel. To the front wheel connected to it, there is the same adjustment mechanism on it. It is the same as the direction rod adjustment method mentioned above, but the difference is that adjusting it is to adjust the toe of the two front wheels, that is, to control the two front wheels. Whether the chakra is an outer or inner horoscope, under normal conditions it should be neither an outer horoscope nor an inner horoscope. Let me introduce a simple adjustment method. I came up with it on my own after seeing a bunch of confused little guys adjust the car for a long time but couldn't adjust it properly. I actually tried it and it worked very well. I only need one little guy to adjust it. Just do the rough work. Preparation: Before adjustment, use a jack to support the front axle and tighten the handbrake to ensure safe operation under the vehicle. 1. Adjust the toe-in 1. Find a long string, and pull the string with the boy to measure the tread distance of the two front wheels. The measurement is from the tread of half the tire height; 2. If the tread distance of the two front tires is If the value is greater than the rear, it means the outside of the splay. Adjust the direction tie rod (the one connected to the front wheel on the driver's side) so that it does not become outside of the splay until the difference between the front and rear is 0; 3. On the contrary, if the tread on the back of the two tires is If the value is greater than the previous one, it means that you are pigeon-toed. Adjust the direction tie rod in the same way until the difference between the front and rear treads is 0; 2. Adjust the steering wheel position 1. Set the direction in the right direction; 2. Let the boy adjust the direction tie rod (note, it is (the one that fixes the rocker arm of the steering gear), and watch the two front wheels reach a position roughly directly ahead; 3. Ask the boy to stop the adjustment, and pull a rope with him. This time, put the rope close to the front and rear wheels on the same side. Check the center tire wall to see if it is all on the same plane; 4. If the ropes on the left and right sides can stick to the tread, the left and right sides are on the same plane, and the steering wheel is in a normal position, it means the adjustment is done; 5. It can be passed Pull the rope left and right to further check whether the toe adjustment is correct. Let’s consider the method yourself.
