[0002] At present, the method of adopting the whole vehicle road to carry the motorcycle leader to carry out the durability test can complete the durability test of the steering system through long time and long mileage road test. However, if only the steering durability of the part components is examined, the method is long in time, low in efficiency, high in cost, and if the leader is manually operated to carry out the durability test, the working time is long, the working strength is large, and the operation feasibility is lacked, because the steering of the leader in the test process has certain requirements, and needs to meet the steering operation speed in the driving process.

[0003] Therefore, how to reduce the test intensity of the motorcycle steering test process and improve the test efficiency becomes a technical problem to be solved by the technical personnel in the field. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a motorcycle steering test bench to reduce the test intensity of the motorcycle steering test process and improve the test efficiency.

[0005] In order to achieve the above-mentioned purpose, the present application discloses the following technical scheme:

[0006] The present application provides a motorcycle steering test bench, which comprises a first support, a second support, a cylinder, a gas source, a control valve, a controller and a power switch,

[0007] The second support is used for supporting the motorcycle;

[0008] One end of the cylinder is rotatably arranged on the first support, and the second end of the cylinder is rotatably connected with the handle of the motorcycle;

[0010] The controller is electrically connected with the control valve to control the ventilation state of the cylinder;

[0011] The power switch is electrically connected with the controller to adjust the on-off of the power supply of the controller.

[0012] In some embodiments, the first support and / or the second support is a frame structure.

[0013] In some embodiments, one end of the cylinder is rotatably connected with the first support through a steering support.

[0014] In some embodiments, the steering support comprises a first steering part, a second steering part, a first rotation shaft and a second rotation shaft, the first steering part is rotatably arranged on the first support through the first rotation shaft, the second steering part is rotatably arranged on the first steering part through the second rotation shaft, the second steering part is connected with one end of the cylinder, and the first rotation shaft and the second rotation shaft are perpendicular to each other.

[0015] In some embodiments, the second steering part is rotatably connected with one end of the cylinder through a third rotation shaft.

[0016] In some embodiments, an elastic member is further arranged between the steering support and the first support.

[0017] In some embodiments, the cylinder further comprises a clamp arranged close to the handle, and the clamp is detachably connected with the handle.

[0018] In some embodiments, the clamp is rotatably connected with the cylinder.

[0019] In some embodiments, the control valve is a two-position three-way electromagnetic reversing valve, an inlet of the control valve is connected with the air source, a first outlet of the control valve is connected with the rodless chamber of the cylinder, and a second outlet of the control valve is connected with the rod chamber of the cylinder.

[0036] The application will be described in further detail below with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the application. The embodiments described are only a part of the embodiments of the application, and not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the application.

[0037] Referring to Figure 1 In order to achieve the above-mentioned purpose, the application discloses the following technical solutions:

[0038] A motorcycle steering test bench (hereinafter referred to as test bench) 10, comprising a first support 1, a second support 2, a cylinder 3, a gas source, a control valve 5, a controller 6 and a power switch 7, the second support 2 is used to support a motorcycle 20; one end of the cylinder 3 is rotatably arranged on the first support 1, and the second end of the cylinder 3 is rotatably connected with a handlebar 23 of the motorcycle 20; the gas source is communicated with the cylinder 3 through the control valve 5, and when the cylinder 3 is extended or retracted, the handlebar 23 is switched between two limit positions; the controller 6 is electrically connected with the control valve 5 to control the ventilation state of the cylinder 3; and the power switch 7 is electrically connected with the controller 6 to adjust the on-off of the power supply of the controller 6.

[0039] When the test bench 10 is used to conduct a durability test on a handlebar 22 of the motorcycle 20, the motorcycle 20 is first erected on the second support 2, the first support 1 is moved to a proper position of the motorcycle 20, the cylinder 3 is connected with the handlebar 23, and the connection between the test bench 10 and the motorcycle 20 is realized. The power switch 7 and the gas source are turned on, the controller 6 controls the conduction state of the control valve 5 according to the set program, so as to realize the extension and retraction of the cylinder 3, and the extension and retraction of the cylinder 3 makes the handlebar 23 switch between two limit positions (equivalent to the limit positions of the handlebar 22), thereby realizing the durability test on the handlebar 22 of the motorcycle 20. Since the handlebar 23 does not need to be manually rotated in the above process, the labor intensity of the test process is reduced. In addition, the handlebar 23 reciprocates between the two limit positions driven by the cylinder 3 in the above test process, thereby improving the test efficiency.

[0040] Hereinafter, the terms "first" and "second" are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features.

[0041] Herein, it is explained that the motorcycle 20 can include a frame 21, a handlebar 22 rotatably arranged on the frame 21, and a handle 23 arranged on the handlebar 22. The handlebar 23 can drive the handlebar 22 to rotate relative to the frame 21 by operation, and thus the rotation angle of the handlebar 23 is the rotation angle of the handlebar 22. Therefore, the limit position of the handlebar 22 can be obtained by obtaining the limit position of the handlebar 23 by operation, as shown in Figure 2 The handlebar 23 includes two limit positions, i.e., a first limit position C1 and a second limit position C2.

[0042] The first support 1 is used to support the cylinder 3, and the second support 2 is used to support the motorcycle 20. On one hand, the front wheel of the motorcycle 20 is separated from the ground, and on the other hand, the whole motorcycle 20 is in a stable standing state, and only the handlebar 22 can rotate. The first support 1 and / or the second support 2 are in a frame structure, so as to reduce the test cost of the test bench 10.

[0043] The cylinder 3 includes a cylinder 3 sleeve and a piston rod, the piston rod is slidably arranged in the cylinder 3 sleeve, so that the inside of the cylinder 3 sleeve is separated into a rod cavity and a rodless cavity. When the rodless cavity is ventilated, the cylinder 3 is elongated, and when the rod cavity is ventilated, the cylinder 3 is shortened. By controlling the air inlet direction of the cylinder 3, the extension and contraction of the cylinder 3 can be realized, and the handlebar 22 can be driven to rotate. In addition, in order to reduce the occurrence of the jamming phenomenon of the cylinder 3 and the handlebar 22 during rotation of the handlebar 22, one end of the cylinder 3 is rotatably connected to the first support 1 through a steering support 31. The steering support 31 can realize steering in at least one direction. The steering support 31 in the example of the present application can also realize steering in two directions, three directions, etc.

[0044] Taking the realization of steering in two directions as an example, the steering support 31 includes a first steering part 311, a second steering part 312, a first rotation shaft 313 and a second rotation shaft 314. The first steering part 311 is rotatably arranged on the first support 1 through the first rotation shaft 313, the second steering part 312 is rotatably arranged on the first steering part 311 through the second rotation shaft 314, the second steering part 312 is connected to one end of the cylinder 3, and the first rotation shaft 313 and the second rotation shaft 314 are perpendicular to each other, as shown in Figure 3 .

[0045] Taking the realization of steering in three directions as an example, on the basis of the structure of steering in two directions, the second steering part is rotatably connected to one end of the cylinder 3 through a third rotation shaft 315. The third rotation shaft 315, the second rotation shaft 314 and the first rotation shaft 313 are perpendicular to each other.

[0046] In addition, in order to further optimize the above scheme, a resilient member is arranged between the steering support 31 and the first support 1, so that the cylinder 3 has sufficient space for movement in the up-down and left-right directions, and is not easy to produce hard interference.

[0047] In this example, the end of the cylinder 3 near the handle 23 is connected by a flexible rope. Alternatively, to improve the operability of the test bench 10, the end of the cylinder 3 near the handle 23 is also provided with an angle 32, which is detachably engaged with the handle 23. This angle 32 may include a first gripper 321, a second gripper 322, and a fastener 323 arranged opposite to each other. A clamping space for holding the handle 23 is formed between the first gripper 321 and the second gripper 322. One end of the first gripper 321 or the second gripper 322 is connected to the cylinder 3, and the other end is connected by the fastener 323. Rotating the fastener 323 adjusts the cross-sectional area of ​​the clamping space, thereby achieving the purpose of clamping the handle 23. Figure 4 As shown.

[0048] To further reduce hard interference, the included angle 32 is rotatably connected to the cylinder 3, and its rotation trajectory is parallel to the rotation trajectory of the faucet 22.

[0049] The above mainly introduces the connection method between cylinder 3 and the first bracket 1, and between cylinder 3 and handle 23. The following details the connection method between control valve 5 and cylinder 3. As described above, changing the air intake state of the rod chamber and rodless chamber of cylinder 3 can achieve the extension and retraction of cylinder 3. Control valve 5 can adjust the air intake state of cylinder 3 by changing the air intake direction. The control valve 5 can be two valves or one valve. Taking control valve 5 as a single valve as an example, this control valve 5 is a two-position three-way solenoid directional valve. The inlet of control valve 5 is connected to the air source, the first outlet of control valve 5 is connected to the rodless chamber of cylinder 3, and the second outlet of control valve 5 is connected to the rod chamber of cylinder 3. When control valve 5 is in the left position, the inlet is connected to the first outlet, and the inlet is disconnected from the second outlet; when control valve 5 is in the right position, the inlet is disconnected from the first outlet, and the inlet is connected to the second outlet. Controller 6 controls the switching of control valve 5 between the left and right positions according to the timing, such as... Figure 1 As shown.

[0050] When control valve 5 is in the left position, air enters the rodless chamber and cylinder 3 extends; when control valve 5 is in the right position, air enters the rod chamber and cylinder 3 shortens.

[0051] Taking control valve 5 as an example, this control valve 5 is a two-position two-way solenoid directional valve, namely the first control valve 515 and the second control valve 525. The inlet of the first control valve 515 is connected to the air source. When the first control valve 515 is in the left position, the inlet and outlet are connected; when the first control valve 515 is in the right position, the inlet and outlet are disconnected. The outlet of the first control valve 515 is connected to the rodless chamber of the cylinder 3. The inlet of the second control valve 525 is connected to the air source, and the outlet of the second control valve 525 is connected to the rod chamber of the cylinder 3. When the second control valve 525 is in the left position, the inlet and outlet are connected; when the second control valve 525 is in the right position, the inlet and outlet are disconnected. The controller 6 controls the switching of the first control valve 515 and the second control valve 525 between the left and right positions according to the timing, such as... Figure 5 As shown.

[0052] When the first control valve 515 is in the left position and the second control valve 525 is in the right position, air enters the rodless chamber and the cylinder 3 extends. When the first control valve 515 is in the right position and the second control valve 525 is in the left position, air enters the rod chamber and the cylinder 3 shortens.

[0053] The aforementioned controller 6 is either a non-programmable PLC or a programmable PLC. Taking a programmable PLC as an example,

[0054] Controller 6 runs its internal program, outputting a main push signal to extend the piston rod, causing the control-connected faucet 22 to rotate inward. Once the piston rod has extended to the appropriate position, it executes a processing program based on a time signal and outputs a contraction command, causing the control-connected faucet 22 to extend outward to its limit position; a stop signal and a hold time command are also output (this process constitutes one complete action cycle). When the timer expires, controller 6, under automatic software control, issues a command to cause faucet 22 to begin reciprocating again, repeating the above process. This cyclical action continues until a set number of cycles (e.g., 20,000) is reached, at which point controller 6 outputs a termination signal, ending the entire experiment.

[0055] See details Figure 6 The built-in control program operates as follows:

[0056] S1: Start-stop control: X0 starts the control, X1 stops the control.

[0057] S2: Left turn (right turn) control.

[0058] S3: Hold left (right) turn for 1300ms.

[0059] S4: Left turn (right turn) return control.

[0060] S5: Left turn (right turn) return to position and hold for 500ms.

[0061] S6: Count control, stop the test when the count reaches 20,000.

[0062] S7: End.

[0063] The power switch 7 provides ±24V DC power supply operating voltage. After being turned off, the controller 6 (PLC) will either be reset or automatically save the data.

[0064] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed, and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. The scope of this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described application concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
