How to judge the direction machine outside the ball head is broken?
Hold the rod dry or straight with your hand. Shake from side to side to see if there is any loosening. If the hand can swing, the condition is not very good. It needs to be replaced in time, otherwise it is easy to fall without direction.
Rack and pinion steering gear is composed of a steering gear integrated with a steering shaft and a rack usually integrated with a steering crossbar. Compared with other forms of steering gear, the main advantages of rack and pinion steering gear are: simple structure, compact; The shell is made of aluminum alloy or magnesium alloy, and the mass of the steering gear is relatively small. Transmission efficiency up to 90%.
The gap between gear and rack due to wear, the use of the spring installed in the back of the rack, close to the active pinion can be adjusted at the pressing force, can automatically eliminate the gap between teeth, which can not only improve the stiffness of the steering system, but also can prevent impact and noise; Small volume occupied by the steering gear; There is no steering rocker arm and straight tie rod, so the steering wheel Angle can be increased; Low manufacturing cost.
