The application of guide pulley in the direction control system
The four-wheel drive car on the track is to rely on the front buffer (bumper, tap) and buffer (Feng Wei) on the guide pulley and the rail (lanes) interaction between the wall and change the direction of travel. So the car can run smoothly with high speed, leading, Pteris, all parts of the assembly, reasonable adjustment has a very close relationship:
1, the leading tail guide pulley after installation (including wings, anti roll bars), turning more flexible, four-wheel drive forward resistance is smaller, the speed is faster. In order to reduce the rotation resistance of the steering wheel, the right amount of grease can be added between each guide wheel and shaft (Huang You).
2 the edge of the guide wheel should be smooth and smooth to reduce the resistance of the car. It is worth mentioning that the ring guide wheel arranged on Audi four-wheel drive car, to reduce the car moving resistance, very useful when the car driving to keep steady.
3 when car at high speed into the corners, will produce large centrifugal force, and through before, during and after the buffer and the guide wheel, in orbit on the wall. Then you need to buffer, especially the leading, have sufficient strength to support the tail (once the deformation occurs, it will result in a "runaway" accident). Due to the design of weak car original buffer for the installation, faucet, car accessories tail is very necessary. In particular, the main accessories, because of its guide wheel preset a certain angle (5~10 degrees), so that the high speed car more stable.
In addition, in the Audi 4x4 swallowtail accessories, adds a new function: anti fly brake. But this function in the absence of circular track fork road race (such as lightning dragon track), do not use (remove brake can).
