转向器是转向系主要构成的关键零件,随着电子技术在汽车中的广泛应用,转向装置的结构也有很大变化。从目前使用的普遍程度来看,主要的转向器类型有4种:有蜗杆销式(WP型)、蜗杆滚轮式(WR型)、循环球式(BS型)、齿条齿轮式(RP型)。这四种转向器型式,已经被广泛使用在汽车上。齿轮齿条式转向器和循环球式转向器,已成为当今世界汽车上主要的两种转向器;而蜗轮蜗杆式转向器和蜗杆销式转向器,正在逐步被淘汰或保留较小的地位。齿轮齿条式转向器的主要优点:结构简单、紧 The steering gear is the key component of the steering system. With the extensive application of electronic technology in the automobile, the structure of the steering gear also has great changes. From the prevalence of the current use of the point of view, there are four main types of steering gear: a worm type (WP type), a worm wheel type (WR type), a recirculating ball type (BS type), a rack and pinion type ). These four steering gear type, has been widely used in the car. Rack and pinion steering gear and recirculating ball steering gear, has become the world’s two major steering vehicles in the world; and worm gear and worm pin steering gear, is gradually being eliminated or retained smaller status. The main advantages of rack and pinion steering gear: simple structure, tight
