Problems solved by technology
[0003] With the development of automobile steering technology, the number of steering mechanism parts increases, making it difficult to measure the free travel angle of the steering wheel of a car
In the prior art, the mechanical steering wheel free travel angle measuring instrument not only has low measurement accuracy but also is extremely inconvenient to install and use. In some cars, it cannot be directly measured, and it needs to remove most of the parts around the steering shaft to measure
The measurement results of the mechanical steering wheel free travel angle measuring instrument are displayed in the form of a pointer, which is troublesome to read

Embodiment Construction
[0017] like figure 1 As shown, the steering wheel free travel angle measuring instrument of the present invention includes a torque sensor 1 , an angle sensor 6 and an angle processing system 8 . The torque sensor 1 is provided with a shorter rotating shaft 2 , and the middle position of the rotating shaft 2 is fixedly connected with the torque sensor 1 . One end of the rotating shaft 2 is provided with a connecting device for connecting the steering wheel steering shaft 14, and the connecting device is a bolt, which is directly screwed into the steering wheel steering shaft 14 during use. At the other end of the rotating shaft 2, that is, the rotating shaft 2 is provided with a turntable 4 above the torque sensor 1, the turntable 4 is similar to a steering wheel, and it is connected with the rotating shaft 2; a flexible shaft 5 is connected to the top of the rotating shaft 2, and the flexible shaft The length of 5 is one meter, and the other end of flexible shaft 5 is fixedl...

The invention discloses a free-stroke angle measuring instrument of a steering wheel, comprising a torsion sensor, an angle sensor and an angle processing system, wherein the torsion sensor is provided with a rotating shaft, one end of the rotating shaft is provided with a steering wheel and connected with the angel sensor, and the torsion sensor and the angle sensor are both connected with the angle processing system. The free stroke angle measuring instrument of the steering wheel adopts an electronic module structure to measure two parameters of torsion and angle and converts the two parameters into electric signals which can be directly displayed a concrete angle value after being processed and analyzed, thereby improving the measuring precision and the measuring speed of the free stroke angle of the steer wheel and achieving an intuitive and perspicuous measuring result; and during measuring, the measuring process is very convenient by only rotating the steering wheel without disassembling parts on an automobile.
Description
technical field [0001] The invention relates to a steering wheel free travel angle measuring instrument. Background technique [0002] The ideal steering operation mechanism is that the steering shaft rotates as soon as the steering wheel starts to rotate, and the steering wheels immediately start to deflect. However, in fact, there are assembly gaps between the steering gear and the various power transmission parts in the steering transmission mechanism, and as the parts wear gradually, these gaps will gradually increase; Elastic deformation, both cause the movement of the steering wheel to lag behind the movement of the steering wheel. Because there is an assembly gap in the steering gear and the steering transmission mechanism, the steering wheel must be idling at an angle to eliminate the gap between the working surfaces of all power transmission parts before the steering wheel can rotate. This idling angle of the steering wheel is the steering wheel free play angle. ...
