Automobile ball head
The outer ball head refers to the hand pull rod head, and the inner ball head refers to the direction machine pull rod head. The outer ball head and the inner ball head are not connected together, they both work together. The ball head of the direction machine is connected to the horn, and the ball head of the hand pull rod is connected to the parallel rod.
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 type steering gear is composed of a steering gear integrated with the steering shaft and a rack usually integrated with the steering bar. 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 at the pressing force can be adjusted, can automatically eliminate the gap between teeth, which can not only improve the stiffness of the steering system, but also can prevent the impact and noise when working; 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
