The invention discloses a novel rack-and-pinion steering gear, which comprises a rack-and-pinion steering gear body, a steering rack is arranged on the rack-and-pinion steering gear body, and a steering worm box is arranged outside one end of a steering rack box barrel outside the steering rack; a gear rack gap automatic adjusting mechanism is arranged at the end of one end of the steering rack, a rack lining is arranged between the inner side of a rack lining sleeve outside the other end of the steering rack box barrel and the steering rack, a dust cover is arranged outside the end of one end of the rack lining sleeve, and one end of the dust cover is connected with the outer portion of one end of the rack lining sleeve in a clamped mode. A steering tie rod at one end of the steering rack is fixedly connected with the end of the steering rack, and a rubber dust cover at the joint of the tail end of the steering rack and the steering tie rod is tightly attached to the rack. According to the rack-and-pinion steering gear, vibration borne by the steering gear is dispersed to the steering gear shell and the adjusting device through the buffering device, so that abrasion of the rack and the pinion is reduced, and abnormal sound during steering is reduced.

    本发明公开了一种噪声较小的新型齿轮齿条式转向器,包括齿轮齿条式转向器本体,在齿轮齿条式转向器本体上设有转向齿条,转向齿条外部转向齿条箱桶的一端外部设有转向蜗杆箱,转向齿条的一端端头处设有齿轮齿条间隙自动调整机构,转向齿条箱桶另一端外部的齿条衬套套管内侧与转向齿条之间设有齿条衬套,齿条衬套套管的一端端头外部设有防尘罩,防尘罩的一端与齿条衬套套管的一端外部卡接连接,转向齿条一端端头的转向横拉杆与转向齿条端头之间固定连接,转向齿条末端与转向横拉杆连接处的橡胶防尘罩与齿条紧密贴合,该齿轮齿条式转向器通过将转向器受到的振动通过缓冲装置分散到转向器壳体及调整装置来减小齿轮齿条的磨损进而减小转向时的异响。
