Description

A sensitivity detection device

Technical Field

The utility model relates to a detection device, in particular to a sensitivity detection device.

Background technique

Car steering sensitivity refers to the speed and degree of vehicle steering response when the driver turns the steering wheel. It depends on factors such as the vehicle's steering system design, steering mechanism, steering ratio and suspension system. The steering ratio refers to the proportional relationship between the angle the driver turns the steering wheel and the actual angle the wheels turn. A smaller steering ratio means that the wheels turn a larger angle when the steering wheel is turned, making the vehicle more sensitive. The steering ratio of different vehicles may vary, depending on the type of vehicle and its purpose.

At present, the method for detecting the steering sensitivity of a car is generally to detect the sensitivity of the car steering wheel rotation through a steering parameter detector. Before the steering parameter detector is used, the steering parameter detector needs to be installed on the steering wheel, and the steering wheel needs to be fixed in multiple positions. The steering parameter detector in the prior art is generally provided with multiple fixed structures, but there is no linkage relationship between these fixing mechanisms. Each fixed structure needs to be manually fixed to the corresponding position of the steering wheel, which takes a certain amount of time.
