Problems solved by technology

However, its installation points are scattered on both sides of the steering gear, which requires a large space in the X direction, and the difference in the Z direction between the steering gear 1' and the sub-frame 2' cannot be too large, otherwise a separate bracket needs to be added, and a separate Brackets cause further increases in cost, weight, installation space, etc.

Abstract

The invention discloses a steering gear assembly and a vehicle steering system. The steering gear assembly comprises a steering gear (5) and an auxiliary vehicle frame (6). At least two X-direction installation points (7) are arranged between the steering gear (5) and the auxiliary vehicle frame (6). The steering gear assembly is characterized by further comprising at least one Z-direction installation point (8), the one or more Z-direction installation points (8) are connected with the auxiliary vehicle frame (6) through one or more X-direction installation points (7) corresponding to the Z-direction installation points (8). The steering gear assembly is simple in structure, easy to install, small in required design space and capable of effectively solving the problems that the input moment of a tubular column type electric power-assisted steering gear fluctuates and a lower cross joint of a steering transmission shaft vibrates due to the fact that a steering gear pull rod receives excitation of a road surface.

Description

technical field [0001] The invention relates to the technical field of automobile equipment, in particular to a steering gear assembly of a vehicle. The invention also relates to a vehicle steering system provided with said steering gear assembly. Background technique [0002] The vehicle steering system is a device used to change or maintain the driving or reversing direction of the vehicle. Its function is to control the driving direction of the vehicle according to the driver's wishes, so it is very important to the driving safety of the vehicle. [0003] The most important part of the steering system is the steering gear. The steering gear (also often referred to as the steering gear) is a set of mechanisms that complete the movement from rotation to linear motion. It is also a reduction transmission device in the steering system. Its function is mainly to increase The magnitude of the force transmitted from the steering wheel to the transmission mechanism and the chang...
