Problems solved by technology

For example, in the case of other company's vehicles as a reference, if there is no relevant specific design information, it will be necessary to conduct a characteristic test of the part after disassembling the vehicle, so a lot of time and work will be required

Embodiment Construction

[0017] Hereinafter, a method for measuring friction force of a steering system according to a preferred embodiment of the present invention will be described in detail based on the drawings.

[0018] figure 1 It is a photograph of a configuration provided for measuring the frictional force of a steering system of a vehicle according to a preferred embodiment of the present invention. Such as figure 1 As shown in FIG. 1 , the vehicle is mounted on a suspension characteristic testing machine such as SPMM, and the SPMM used here is a suspension characteristic testing machine sold by AB Dynamics in the United Kingdom. However, it is also possible to configure another test device and perform the test.

[0019] First, a method of measuring the frictional force in the steering rack will be described.

[0020] Such as figure 1 As shown, the installation is as follows: the vehicle is fixed to the SPMM and the front wheels of the vehicle are placed on the rotatable circular plate on...

Abstract

The invention provides a method for measuring force of friction of a steering system in a vehicle without testing each part after disassembling the vehicle.

Description

technical field [0001] The invention relates to a method for measuring the friction force of the steering system of a vehicle, in particular to a method for measuring the friction force of the steering system of a vehicle which can obtain the friction force of the steering system with less time and work without disassembling the vehicle and testing each component Force measurement method. Background technique [0002] It is known that friction generally present in a steering system of a vehicle greatly affects vehicle performance such as on-center feel of a steering wheel or straight-line running stability. This is because the friction force of the steering system has a large influence on the steering wheel torque transmitted to the steering wheel. The friction force of the steering system is generally caused by the friction force of the rack and pinion mechanism constituting the steering system and the friction force generated by the steering joint. Regarding this aspect,...
