The cam 31 is sleeved on the output shaft 22 and eccentrically arranged with the output shaft 22. One end of the rotatable member 32 is rotatably connected to the fixed component 1. The pushing member 33 is connected to the rotatable member 32 and abuts against the cam 31. One end of the elastic member 34 is connected to the other end of the rotatable member 32, and the other end of the elastic member 34 is connected to the fixed component 1, which is used to provide an elastic force for the rotatable member 32 to return to its original position after rotation, so that the rotatable member 32 pushes the cam 31 and the output shaft 22 to return to their original position through the pushing member 33.

[0051] When the steering of the steering wheel is simulated by the above device, the steering wheel is connected to the output shaft 22, and then the input shaft 21 is rotated. The rotating input shaft 21 drives the output shaft 22 to rotate through the transmission member 23, and the rotating output shaft 22 drives the rotating end of the angle sensor 24 to rotate. The angle sensor 24 outputs a rotation angle signal to the simulation system, and the rotation circle speed of the steering wheel is restored by the simulation system to achieve the simulation of the steering wheel operation; the output shaft 22 drives the cam 31 to rotate during the rotation process, and the rotating cam 31 drives the rotating member 32 to rotate through the pushing member 33, and the rotating member 32 stretches the elastic member 34. When the human hand leaves the steering wheel, the rotating member 32 pushes the rotating member 32 to reset under the action of the elastic member 34. During the resetting process of the rotating member 32, the cam 31 is driven to rotate through the pushing member 33, so that the eccentrically set cam 31 returns to the center, thereby achieving the automatic return of the steering wheel simulation mechanism.

[0052] It can be understood that the fixing assembly 1 includes a box body 11 and an end cover 12. The end cover 12 is arranged relative to the box body 11 and is detachably connected to the end cover 12 by screws.

[0053] In one embodiment, the simulation component 2 also includes a bracket 25, the bracket 25 is connected to the end cover 12, the fixed end of the angle sensor 24 is connected to the bracket 25 and connected to the end cover 12 via the bracket 25, and the output end of the angle sensor 24 is connected to the output shaft 22.

[0054] By providing the bracket 25 , the angle sensor 24 is fixed relative to the end cover 12 .

[0055] It can be understood that the rotating member 32 can be a rotating rod, a rotating block, etc.

[0056] It can be understood that one end of the rotating member 32 can be rotatably connected to the end cover 12 via a rotating shaft or a rotating pin.

[0057] It can be understood that the transmission member 23 can be a pulley belt transmission mechanism, a gear transmission mechanism, a sprocket transmission mechanism, etc.

[0058] In one embodiment, the transmission member 23 includes a transmission shaft 231, a first gear 232, a second gear 233, a third gear 234 and a fourth gear 235. The two ends of the transmission shaft 231 are rotatably connected to the housing 11 and the end cover 12 respectively, and the axes of the transmission shaft 231, the input shaft 21 and the output shaft 22 are arranged parallel to each other. The first gear 232, the second gear 233, the third gear 234 and the fourth gear 235 are built into the housing 11. The first gear 232 and the second gear 233 are respectively mounted on the input shaft 21 and the transmission shaft 231 and mesh with each other. The third gear 234 and the fourth gear 235 are respectively mounted on the transmission shaft 231 and the output shaft 22 and mesh with each other.

[0059] Since the rotation speed of the steering wheel of some heavy-duty vehicles reaches more than 5 circles, if the rotation speed of the input shaft 21 and the output shaft 22 is the same, the input shaft 21 rotating more than five circles will drive the output shaft 22 to rotate more than 5 circles. In the present application, by setting the transmission shaft 231, the first gear 232, the second gear 233, the third gear 234 and the fourth gear 235, the transmission shaft 231, the first gear 232, the second gear 233, the third gear 234 and the fourth gear 235 form a two-stage gear structure, so that the torsion angle of the output shaft 22 is compressed within 300°, thereby avoiding excessive rotation speed of the output shaft 22.

[0060] It can be understood that one end of the transmission shaft 231, the input shaft 21, and the output shaft 22 are rotatably connected to the end cover 12 through bearings, and the other ends are rotatably connected to the housing 11 through bearings.

[0061] It can be understood that the pushing member 33 can be fixedly connected to the rotating member 32 or rotatably connected to the rotating member 32 .

[0062] In one embodiment, the pushing member 33 includes a rotating portion 331 . The rotating portion 331 is rotatably connected to the rotating member 32 . The rotating portion 331 rolls against a peripheral wall of the cam 31 .

[0063] By rotatably connecting the rotating part 331 to the rotating member 32 , rolling friction occurs between the rotating part 331 and the cam 31 , which can reduce the friction between the rotating cam 31 and facilitate the rotation of the rotating part 331 relative to the cam 31 .

[0064] In one embodiment, a notch 31 a is formed on the peripheral wall of the cam 31 relative to the rotating portion 331 , and the inner wall of the notch 31 a and the peripheral wall of the cam 31 are smoothly transitioned.

[0065] By providing the notch 31a, during the process of the rotating part 331 being reset under the action of the elastic member 34, when the rotating part 331 rotates to the notch 31a during the reset process, it can engage with the notch 31a, which can eliminate the inertia force during the reset and increase the rotation damping of the input shaft 21 when it starts to rotate.

[0066] It can be understood that the rotating portion 331 can be rotatably connected to the cover plate via a rotating shaft, a rotating pin, a bearing, etc.

[0067] In one embodiment, the pushing member 33 further includes a fixing pin 332 , the fixing pin 332 is connected to the rotating member 32 , and the rotating portion 331 is rotatably mounted on the fixing pin 332 .

[0068] By providing the fixing pin 332 and making the rotating part 331 rotatably fitted on the fixing pin 332 , the rotating connection between the rotating part 331 and the rotating member 32 is achieved.

[0069] It can be understood that the rotating portion 331 can be a sleeve, a ring, etc.

[0070] In one embodiment, the rotating portion 331 is a bearing.

[0071] By setting the rotating part 331 as a bearing and abutting the cam 31 through the bearing, the rotation damping between the cam 31 and the bearing can be reduced, so that the cam 31 can rotate relative to the rotating part 331 more easily.

[0072] In one embodiment, the return assembly 3 also includes a first threaded member 35, one end of the first threaded member 35 is threadedly connected to the end cover 12, the other end of the first threaded member 35 is hinged to the other end of the elastic member 34, and the elastic member 34 is hinged to the end cover 12 via the first threaded member 35.

[0073] The rotating first threaded member 35 is threadedly connected to the end cover 12 . During the rotation of the first threaded member 35 , the first threaded member 35 will move along its own axial direction relative to the end cover 12 , so as to adjust the tension degree of the elastic member 34 and the elastic tensile force of the elastic member 34 .

[0074] It can be understood that the first threaded member 35 can be a screw, a stud, etc.

[0075] In one embodiment, the return assembly 3 further includes at least one damper 36 , one end of the damper 36 is hinged to the rotating member 32 , and the other end of the damper 36 is hinged to the fixing assembly 1 .

[0076] By providing the damper 36, the rapid rotation of the rotating member 32 can be limited, so that the rotation of the input shaft 21 is more stable. In addition, the damper 36 can eliminate the inertia force of the cam 31 during resetting, thereby preventing the cam 31 from swinging repeatedly during the resetting process.

[0077] In one embodiment, the return assembly 3 also includes a second threaded member 37, one end of the second threaded member 37 is threadedly connected to the fixing assembly 1, the other end of the second threaded member 37 is hinged to the other end of the damper 36, and the damper 36 is hinged to the fixing assembly 1 via the second threaded member 37.

[0078] The rotating second threaded member 37 is threadedly connected to the end cover 12 . During the rotation of the second threaded member 37 , the second threaded member 37 will move along its own axial direction relative to the end cover 12 , so as to adjust the tension degree of the damper 36 and the damping of the damper 36 .

[0079] It can be understood that the second threaded member 37 can be a screw, a stud, etc.
