The invention relates to the technical field of vehicle steering gears, and provides a vehicle and a gear rack steering gear thereof. The gear rack steering gear comprises a shell and a rack penetrating through the shell. Inner ball head assemblies are arranged at the two ends of the rack; a limiting structure is arranged on the face, opposite to the inner ball head assembly, of the shell for blocking match with the inner ball head assembly; springs are arranged at the two ends of the rack respectively; the springs are provided with blocking ends matched with the limiting structure in a blocking mode when the rack acts, and when the gear rack steering gear returns, intervals are formed between the blocking ends of the springs and the corresponding limiting structures on the shell. According to the steering gear, the stretching time and deformation of the springs on the two sides can be greatly shortened, the fatigue speed of the springs is effectively reduced, abrasion between the rackand the springs is reduced or even avoided, and the service life of the whole steering gear is prolonged; and the force for driving the rack to move is greatly reduced, so that the operation hand feeling is good.

    本发明涉及车辆转向器技术领域,提供了一种车辆及其齿轮齿条转向器,齿轮齿条转向器包括壳体和贯穿壳体设置的齿条,齿条的两端设置有内球头总成,壳体上与内球头总成的相对面上设置有限位结构,以用于与内球头总成挡止配合,所述齿条的两端均设有弹簧,所述弹簧具有在齿条动作时与所述限位结构挡止配合的挡止端,在齿轮齿条转向器回正时,所述弹簧的挡止端与壳体上对应的限位结构之间具有间隔。这种转向器能大大缩短两侧弹簧发生伸缩的时间和变形量,有效延缓弹簧发生疲劳的速度,减少甚至避免了齿条与弹簧之间的磨损,延长整个转向器的使用寿命;并大大减小驱动齿条移动的力,使操作手感较好。
