Technical Field

[0001] The utility model relates to the technical field of steering gears, in particular to a steering gear with good stability. Background Technique

[0002] A steering gear is a machine that helps the driver apply force while turning the steering wheel, so as to reduce the force exerted by the driver when turning, and achieve the purpose of making it easy and convenient for the driver to drive. It is mainly divided into rack and pinion steering and worm and worm gear steering. There are roughly three types of power steering devices on the market: electric motor electric power steering, rack and pinion hydraulic power steering, and electro-hydraulic power steering. With the development of society, steering gears are widely used.

[0003] At present, when most steering gears are in use, the coupling shafts of the steering gears are fixed by using clamps and bolts. Since the clamps will wear and become loose during long-term use, it is not conducive to the use of the equipment, and improvements are needed in this regard. Content of the Utility Model
