[0049] The following reference Figures 1 to 4 This application describes the vehicle suspension bridge angle detection device and tractor according to embodiments of the present application.

[0050] See Figures 1 to 4 As shown, an embodiment of this application provides a vehicle suspension bridge angle detection device. This device includes a fixing member 1, a mounting bracket 2, a detection element 5, a first transmission mechanism, and a second transmission mechanism 4. The fixing member 1 is fixed to a designated position on the vehicle body. The detection element 5 is mounted on the fixing member 1, and the mounting bracket 2 is mounted on the suspension bridge rocker arm. The fixing member 1 and the mounting bracket 2 are connected via the first transmission mechanism, and the second transmission mechanism 4 is connected to the detection element 5 via the first transmission mechanism. When the mounting bracket 2 moves synchronously with the suspension bridge rocker arm, the movement of the suspension bridge rocker arm is transmitted to the first and second transmission mechanisms 4. After a series of transmissions, the movement of the suspension bridge rocker arm is transmitted to the detection element 5, which detects the movement angle of the suspension bridge rocker arm. The detection result of the detection element 5 reflects the current position of the suspension bridge. It should be noted that the suspension bridge in this embodiment can specifically be a suspension front axle.

[0051] Specifically, the fastener 1 is plate-shaped, and is provided with a first mounting portion 101 and a second mounting portion 102 at intervals. The detection element 5 is disposed on the first mounting portion 101, and the second mounting portion 102 is used to connect with a designated position on the vehicle, thereby fixing the fastener 1 to the designated position. Preferably, both the first mounting portion 101 and the second mounting portion 102 are hole structures that penetrate the two sides of the plate of the fastener 1. More preferably, the number of first mounting portions 101 and the number of second mounting portions 102 are both at least two to ensure connection strength.

[0052] Preferably, the fastener 1 is also provided with a hollowed-out portion 103, which can reduce its own weight on the one hand, and provide clearance space for the second connecting ball head 304 described below on the other hand.

[0053] Furthermore, the detection element 5 is specifically an angle sensor commonly used in the prior art. The detection element 5 includes a body portion 501 and a detection shaft 502 disposed on the body portion 501. The detection shaft 502 is capable of rotating relative to the body portion 501 about its own axis. The body portion 501 is provided with connecting portions for threading a screw. The number of connecting portions is the same as the number of first mounting portions 101 and they are arranged in a one-to-one correspondence. Each connecting portion is positioned opposite a first mounting portion 101. After the screw is threaded through each set of connecting portions and first mounting portions 101, it is locked with a nut.

[0054] Furthermore, the mounting support 2 includes a first plate portion 201 and a second plate portion 202. The first plate portion 201 and the second plate portion 202 are set at an angle. The first plate portion 201 is connected to the suspension bridge rocker arm, and the first transmission mechanism is connected to the second plate portion 202.

[0055] Further, the first transmission mechanism includes a first connecting rod 301, a second connecting rod 302, a first connecting ball head 303, and a second connecting ball head 304. One end of the first connecting rod 301 is provided with a first limiting cavity, which has an opening. The other end of the first connecting rod 301 is provided with a second limiting cavity. The first connecting ball head 303 includes a first rod portion 3031 and a first head 3032. The first rod portion 3031 is connected to the second plate portion 202. The first head 3032 is spherical and enters the first limiting cavity through the opening and is confined within the first limiting cavity. Preferably, the opening of the first limiting cavity is riveted in the circumferential direction to form a constricted opening, so that the first head 3032 can rotate within the first limiting cavity and will not come out of the first limiting cavity.

[0056] The structure of the second connecting ball joint 304 is the same as that of the first connecting ball joint 303, including a second rod portion and a second head disposed on the second rod portion. The second rod portion is connected to one end of the second connecting rod 302, and the second head is inserted into the second limiting cavity through the opening of the second limiting cavity, so that the second head can rotate within the second limiting cavity and be limited within the second limiting cavity. By setting the first connecting ball joint 303 and the second connecting ball joint 304, not only can installation errors be offset, but also the relative lateral and longitudinal movements between the suspension bridge rocker arm and the vehicle body during vehicle operation can be offset.

[0057] The second connecting rod 302 is elongated, with a second rod portion connected to one end of the second connecting rod 302. Preferably, the second rod portion passes through the second connecting rod 302 and is rotatable relative to the second connecting rod 302. A connecting hole is provided at the end of the second rod portion away from the second connecting rod 302, and a central shaft hole is provided at the middle position of the second rod portion.

[0058] Furthermore, the second transmission mechanism 4 includes a third connecting rod 401 and a lever 402. Preferably, the third connecting rod 401 is arranged parallel to the second connecting rod 302, and the third connecting rod 401 and the second connecting rod 302 are distributed on both sides of the fixing member 1. One end of the third connecting rod 401 is provided with a hole through which the detection shaft 502 of the detection member 5 passes. The other end of the third connecting rod 401 is provided with a through hole 4011, and the lever 402 passes through both the connecting hole and the through hole 4011. When the first connecting rod 301 drives the second connecting rod 302 to move, the second connecting rod 302 can drive the third connecting rod 401 to move, causing the detection shaft 502 to rotate and triggering a detection signal. It should be noted that the perforation 4011 is an elongated hole, specifically a waist-shaped hole, which can prevent the third link 401 from moving beyond its range in the front-back direction, causing damage to the second transmission mechanism 4 or the detection component 5. It should be noted that the front-back direction here refers to the length direction of the third link 401, and the movement path of the third link 401 is a reciprocating motion along its length direction.

[0059] Furthermore, the vehicle suspension bridge angle detection device also includes a connecting shaft 6, which passes through the central shaft hole of the second connecting rod 302. One end of the connecting shaft 6 is located on the side of the second connecting rod 302 closer to the first connecting rod 301, and the other end of the connecting shaft 6 passes through the central shaft hole and is connected to the fixing member 1. The connection method can be, but is not limited to, welding. When the first connecting rod 301 pushes the second connecting rod 302, the second connecting rod 302 can rotate about the connecting shaft 6 as a pivot axis.

[0060] Furthermore, the axis of the detection shaft 502 and the axis of the connecting shaft 6 are distributed along the same straight line. When the second connecting rod 302 rotates, the lever 402 enables the third connecting rod 401 to move synchronously with the second connecting rod 302. In turn, the third connecting rod 401 drives the detection shaft 502 to rotate. Since the detection shaft 502 and the connecting shaft 6 are coaxially arranged, the movement amplitude of the detection shaft 502 is the same as that of the connecting shaft 6, ensuring the synchronicity of the movement process of the detection shaft 502, the second connecting rod 302 and the first connecting rod 301, avoiding angle transmission distortion, and thus improving the accuracy of the detection results of the detection component 5 in reflecting the movement angle of the suspension bridge rocker arm.

[0061] Furthermore, the vehicle suspension bridge angle detection device also includes a retaining spring 7. The retaining spring 7 is sleeved on the connecting shaft 6 and located on the side of the second connecting rod 302. Preferably, in this embodiment, there are two retaining springs 7. One retaining spring 7 is sleeved on the end of the connecting shaft 6 near the first connecting rod 301, and the other retaining spring 7 is sleeved on the connecting shaft 6 and located between the second connecting rod 302 and the fixing member 1. Preferably, a gap is formed between the retaining spring 7 and the side wall of the second connecting rod 302, that is, the retaining spring 7 and the second connecting rod 302 are spaced apart, so that a counteracting gap is formed between the retaining spring 7 and the second connecting rod 302 to allow the second connecting rod 302 to undergo a certain degree of lateral displacement. Even if the first connecting ball joint 303 and / or the second connecting ball joint 304 are damaged, the counteracting gap can still counteract a certain relative movement. The retaining spring 7 forms a double protection between the two connecting ball joints, which is firm and reliable.

[0062] In the operation of the vehicle suspension bridge angle detection device provided in this application, as the rocker arm moves, the movement of the suspension bridge rocker arm is transmitted to the second link 302 via the first link 301. During this process, the movement of the suspension bridge rocker arm transmitted from the first link 301 to the second link 302 is not converted into the rotational movement of the second link 302. The lever 402 and the third link 401 drive the detection shaft 502 of the detection element 5 to move, thereby triggering the detection of the detection element 5. It can be seen that this vehicle suspension bridge angle detection device converts the movement of the suspension bridge rocker arm into rotational movement and transmits it to the detection element 5 through the first transmission mechanism and the second transmission mechanism 4. The detection element 5 performs the detection and outputs the detection result. The angle of the suspension bridge has a certain impact on the stability, handling and driving trajectory control of the vehicle. The output result of this vehicle suspension bridge angle detection device can reflect the above performance, so as to optimize the suspension bridge structure and improve the vehicle's passability and stability.

[0063] In summary, the vehicle suspension bridge angle detection device provided in this application effectively improves the synchronization of movement between the suspension bridge rocker arm and the detection component 5, effectively avoids angle transmission distortion, and thus improves the accuracy of suspension bridge angle detection.

[0064] The embodiments of this application also provide a tractor that includes the vehicle suspension bridge angle detection device described in any of the above embodiments, and thus has all the beneficial technical effects of the vehicle suspension bridge angle detection device, which will not be repeated here.

[0065] This tractor can accurately detect the angle of the suspension bridge using the aforementioned vehicle suspension bridge angle detection device. This allows for the determination of the suspension bridge's position and performance, facilitating structural optimization of the suspension bridge and improving the tractor's passability on various road surfaces as well as driver comfort.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
