Embodiment 1

[0082]A steering wheel deflection angle measuring device, the measuring device comprises a stay wire 6 and an upper bracket 1, a lower bracket 2, and a main shaft 3 arranged coaxially, the bottom of the main shaft 3 is fixedly connected to the top of the lower bracket 2, and the main shaft 3 Rotate with the upper bracket 1, the top of the upper bracket 1 is fixedly provided with a dial 4; the upper bracket 1 is fixedly provided with three upper adjustment arms 11, and the angle between two adjacent upper adjustment arms 11 is 120°, the lower bracket 2 is fixedly provided with three lower adjusting arms 21 corresponding to the upper adjusting arms 11 one by one, the angle between two adjacent lower adjusting arms 21 is 120°, and each of the The corresponding upper adjustment arm 11 is connected with the lower adjustment arm 21 by a positioning claw 5; the positioning claw 5 includes an upper connecting rod 51 and a lower connecting rod 52, and one end of the upper connecting rod...

Embodiment 2

[0093] Embodiment 2 is basically the same as Embodiment 1, and its difference is:

[0094] The pull wire 6 is arranged in the pull wire box 10, and the pull wire box 10 is sleeved on the main shaft 3. The pull wire box 10 and the main shaft 3 are rotatably matched. Connect with sucker 7 behind the hole; The diameter of described backguy 6 is 0.3mm, and the total length of backguy 6 in described backguy box 10 is 1.5m; The tension is 10N; the diameter of the suction cup 7 is 50mm.

Embodiment 3

[0096] Embodiment 3 is basically the same as Embodiment 2, and its difference is:

[0097] The step S7, adjusting the position of the steering tie rod according to the calculated interference amount d includes:

[0098] If in step S5, when the vehicle to be tested is fully loaded, the steering wheel is deflected to the right relative to the vehicle to be tested when it is unloaded to ensure that the vehicle can go straight, then adjust the position of the longitudinal steering rod forward, and the adjusted distance is d;

[0099] If in step S5, when the vehicle under test is fully loaded, the steering wheel is deflected to the left relative to the vehicle under test when it is unloaded so that the vehicle can go straight, then adjust the position of the longitudinal tie rod backward, and the adjusted distance is d.

Abstract

A steering wheel deflection angle measuring device comprises a stay wire, an upper support, a lower support and a main shaft, the upper support, the lower support and the main shaft are coaxially arranged, the bottom of the main shaft is fixedly connected with the top of the lower support, the main shaft is rotationally matched with the upper support, and a dial is fixedly arranged at the top of the upper support; a plurality of upper adjusting arms are fixedly arranged on the upper support, lower adjusting arms in one-to-one correspondence with the upper adjusting arms are fixedly arranged on the lower support, each pair of corresponding upper adjusting arms and lower adjusting arms is connected through an upper connecting rod and a lower connecting rod, and the upper connecting rods, the upper adjusting arms, the lower adjusting arms and the lower connecting rods are sequentially hinged. A clamping jaw used for clamping a steering wheel is arranged at the joint of the upper connecting rod and the lower connecting rod. Two ends of the stay wire are respectively connected with the main shaft and the sucker. According to the truck steering system adjusting method, the position of a steering longitudinal pull rod is adjusted by measuring the deviation of the angle of a steering wheel when a truck is in a no-load state and a full-load state. According to the design, the driving experience and safety of the truck can be improved.

Description

technical field [0001] The invention relates to a truck steering system, in particular to a truck steering wheel deflection angle measuring device and a truck steering system adjustment method, and is particularly suitable for truck steering wheel deflection angle measurement and steering system adjustment. Background technique [0002] When the load of the car changes, due to the gap and interaction between the steering rod, steering ball joint, steering knuckle arm and other components in the steering system, the steering wheel of the truck will deflect to a certain extent after being loaded from no load to full load. , the steering wheel deflection problem will affect the driving experience, especially in the field of trucks, when the truck is fully loaded, the steering wheel deflection is too large will affect driving safety. Therefore, the deflection angle of the truck under different loads can reflect the rationality of the steering system design. After the vehicle is...
