Since the reform and opening up, China’s auto industry has developed rapidly. As one of the key components of the automobile, the steering system has also been developed accordingly, and a situation of specialized and serialized production has basically been formed. According to data, there are many steering gear factories in foreign countries, all of which have developed into large-scale professional factories, with an annual output of more than one million units, monopolizing the production of steering gear, and selling points all over the world.
The usage dynamics of modern automobile steering gear
With the rapid development of the automobile industry, the structure of the steering gear has also changed a lot. There are many structures of automobile steering gears. From the perspective of the popularity of use, there are 4 main types of steering gears: worm shaft type (WP type), worm roller type (WR type), recirculating ball type (BS type), tooth Rack and pinion type (RP type). These four types of steering gear have been widely used in automobiles.
It is understood that in the world, automobile recirculating ball steering gears account for about 45%, rack and pinion steering gears account for about 40%, worm roller steering gears account for about 10%, and other types of steering gears account for 5%. The recirculating ball diverter has been developing steadily. In Western European passenger cars, rack and pinion steering gear has been greatly developed. The characteristics of Japanese automobile steering gear are that the proportion of recirculating ball steering gear is increasing. Various types of vehicles equipped with different types of engines in Japan use different types of steering gear. The recirculating ball steering gear used in buses has been 62.5% in the 1960s has grown to 100% today (the worm roller diverter has been eliminated on buses). Most of the large and small trucks use the recirculating ball steering gear, but the rack and pinion steering gear has also been developed. The recirculating ball steering gear for mini trucks accounts for 65%, and the rack and pinion type accounts for 35%.
