Abstract

The invention discloses a steering gear of an automobile steering system, the automobile steering system and an automobile. The steering gear of the automobile steering system comprises a steering input shaft and a steering execution device (200). The steering input shaft is used for receiving the steering torque from a steering wheel (300). The steering execution device (200) is used for driving steering wheels to steer. The steering gear further comprises a drive ratio adjusting device (100), and the steering input shaft is in drive connection with the steering execution device (200) through the drive ratio adjusting device (100). According to the scheme, the automobile can achieve quick steering by a small steering wheel turning angle at a low speed and can achieve safe steering by a big steering wheel turning angle at a high speed, so that the traveling stability and safety of the automobile are kept.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a steering gear of an automobile steering system, an automobile steering system and an automobile. Background technique [0002] The steering system is an important part of the car. The steering system is a series of devices used to change or maintain the driving direction of the car. Among them, the ratio of the steering angle of the steering wheel to the steering wheel is the steering gear ratio. [0003] In existing steering systems (see figure 1 ), the input shaft A is connected to the original steering gear B, so that the steering transmission ratio from the steering wheel to the steering wheel is fixed. When driving at low speeds, light steering is generally achieved by reducing the damping of the steering system; while driving at high speeds, generally Safe steering is ensured by increasing the damping of the steering system. However, when the driver actually drives the car, h...
