The invention relates to a novel gear rack steering gear which comprises a gear shaft used for transmitting rotation force of an automobile steering wheel; the rack shaft is connected with the gear shaft in a matched mode and used for converting rotating motion of the steering wheel into transverse moving motion. The two steering tie rods are connected with the rack shafts in a matched mode, the other ends of the steering tie rods are connected with automobile wheels, and the automobile wheels are pushed to steer in the transverse movement process of the rack shafts; wherein the gear shaft is connected with a hydraulic power assisting device which is used for conveying a proper amount of oil according to the rotation amplitude of the rack shaft, so that the rack shaft easily pushes automobile wheels to steer in the moving process; the rack shafts are variable in diameter, and the diameter of one end close to the matching position of the rack shafts is larger than that of the other end, so that the overall light weight is achieved while the steering strength is guaranteed.

    本发明为一种新型齿轮齿条转向器,包括:齿轮轴,用于传递汽车方向盘的转动的力;齿条轴,与齿轮轴适配连接,用于将方向盘的转动运动转变为横向移动运动;两个的转向横拉杆,与齿条轴适配连接,其另一端与汽车车轮相连接,在齿条轴横向运动的过程中,推动汽车车轮转向;其中,齿轮轴连接有液压助力装置,用于根据齿条轴的转动幅度输送适应的油量,以实现齿条轴在移动的过程中轻松推动汽车车轮转向;齿条轴为变径设置,靠近齿条轴与齿条轴配合处的一端的直径大于另一端的直径,以实现保证转向强度的同时整体的轻量化。
