Technical Field
[0001] This utility model relates to the field of clutch detection technology, specifically a motorcycle clutch torque measuring device. Background Technology
[0002] During the production of clutches, torque testing is required on the assembled clutches. If the preset requirements are not met, reassembly and adjustment are necessary. A search revealed a multi-station clutch torque measuring device in Chinese patent CN117288463A. This device includes symmetrically arranged support seats, an interval conveying mechanism at the top of the support seats, a discharge baffle at the end of the interval conveying mechanism, a multi-station rotary processing table at the bottom of the discharge baffle, a detachable spline clamping device at the top of the multi-station rotary processing table, a flywheel clamping device on the side of the multi-station rotary processing table, and a discharge mechanism at the end of the multi-station rotary processing table. This device addresses the technical problem that current clutch torque measuring devices mostly rely on manual operation and require connecting the clutch to the testing equipment, resulting in complex procedures and low torque testing efficiency.
[0003] However, in actual use, this solution is relatively complex, which makes the assembly of motorcycle clutches inconvenient and inefficient, and it cannot be applied to a large number of motorcycle clutch measurement operations. Utility Model Content
[0004] To address the problems of complex structure and inconvenient operation of existing torque measuring devices, this utility model provides a motorcycle clutch torque measuring device.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0006] A motorcycle clutch torque measuring device includes a base frame. Side plates and a lifting mechanism are respectively located on both sides of the top surface of the base frame. A measuring device is located on one side of the lifting mechanism. The measuring device includes a torque sensor, with a connecting seat mounted on one side of the torque sensor. A docking shaft is mounted on the sensing end of the torque sensor away from the connecting seat. A propulsion mechanism is located on one side of the side plates. A three-jaw chuck is mounted on one end of the propulsion mechanism, and the three-jaw chuck and the docking shaft are on the same axis. Further, the lifting mechanism includes a vertical plate with a vertical groove inside. A slider is slidably connected inside the vertical groove, and screws are inserted into the corners of the slider, connecting the slider to the corners of the connecting seat via screws.
[0007] The beneficial effect of adopting the above-mentioned further solution is that the vertical groove inside the lifting mechanism's vertical plate slides in conjunction with the slider, and the slider is connected to the connecting seat by screws, enabling the vertical position adjustment of the measuring device. This structure facilitates flexible adjustment of the height of the torque sensor and the docking shaft according to different specifications of motorcycle clutches, ensuring accurate docking with the clutch and improving the versatility and applicability of the measuring device.
[0008] Furthermore, a motor is installed on the top surface of the vertical plate, the output end of the motor extends into the interior of the vertical groove and is connected to a lead screw, one end of which is threaded to one side of the slider.
[0009] The beneficial effect of adopting the above-mentioned further solution is that the motor is connected to the slider via a transmission screw, thereby realizing automated lifting control.
[0010] Furthermore, the bottom end of the lead screw is rotatably connected to the inner bottom end of the vertical groove.
[0011] The beneficial effect of adopting the above-mentioned further solution is that it provides a stable support point for the lead screw, ensures that the lead screw will not move axially during the rotational transmission process, ensures that the slider rises and falls smoothly along the vertical groove, and thus makes the movement of the measuring equipment more stable and reliable, avoiding the impact of lead screw instability on measurement accuracy.
[0012] Furthermore, the propulsion mechanism includes a hydraulic cylinder, the output end of which passes through the side plate and is connected to a fixed seat, one side of which is connected to the outer wall of the three-jaw chuck.
[0013] The advantage of adopting the above-mentioned further solution is that by using a hydraulic cylinder drive, with its output end connected to the three-jaw chuck via a fixed seat, a stable and large thrust can be provided. The hydraulic cylinder can quickly and smoothly push the three-jaw chuck closer to or away from the docking shaft, achieving precise installation and disassembly of the clutch.
[0014] Furthermore, limit rods are installed on both sides of the fixed base, and one end of each limit rod is inserted and connected to both sides of the side plate.
[0015] The beneficial effect of adopting the above-mentioned further solution is that it provides guidance and limiting for the movement of the propulsion mechanism. When the hydraulic cylinder pushes the fixed seat and the three-jaw chuck to move, the limiting rod can prevent them from deviating or wobbling, ensuring that the three-jaw chuck always remains coaxial with the docking shaft, thus guaranteeing the accuracy of the clutch installation position.
[0016] Furthermore, the base frame includes a base plate, and fixing bolts are inserted at the corners of the base plate. The base plate is connected to the bottom surfaces of the side plates and the upright plates respectively by fixing bolts.
[0017] The advantages of adopting the above-mentioned further solutions are that it facilitates the assembly and disassembly of the device, and makes operation simple during equipment maintenance, transportation, or layout adjustments. At the same time, the fixing bolt connections ensure a firm connection between the components, enhancing the structural stability of the entire measuring device and keeping it stable during measurement.
[0018] Furthermore, support feet are installed on both sides of the bottom surface of the base plate.
[0019] The beneficial effects of adopting the above-mentioned further solution are that the measuring device can be supported so that the base frame is kept at a certain distance from the ground. On the one hand, this can prevent ground moisture and debris from corroding the base frame and protect the bottom components of the device; on the other hand, it can adjust the level of the device so that the measuring device can remain stable in different ground environments and ensure that the device will not shake due to uneven ground during the measurement process, thus providing a stable foundation for accurately measuring the torque of the motorcycle clutch.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] This motorcycle clutch torque measuring device, through the cooperation of a side plate, lifting mechanism, measuring equipment, propulsion mechanism, and three-jaw chuck, enables a simpler torque measurement function for motorcycle clutches.

The torque sensor of the measuring equipment is connected to the lifting mechanism via a connecting seat, and the docking shaft is used to connect to the motorcycle clutch, accurately sensing the transmitted torque. The propulsion mechanism drives the three-jaw chuck, and the three-jaw chuck is aligned with the axis of the docking shaft, facilitating precise fixing of the clutch and docking with the shaft, thus achieving accurate measurement of the motorcycle clutch torque and meeting the requirements for clutch performance testing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] As one embodiment of this utility model, the lifting mechanism 300 further includes a vertical plate 3001, with a vertical groove 3002 inside the vertical plate 3001. A slider 3003 is slidably connected inside the vertical groove 3002, and screws are inserted at the corners of the slider 3003.

[0032] As an embodiment of this utility model, a motor 3005 is further installed on the top surface of the vertical plate 3001.

One end of the lead screw 3004 is threadedly connected to one side of the slider 3003. The motor 3005 is threadedly connected to the slider 3003 through the lead screw 3004 to realize automated lifting control.
[0033] As an embodiment of this utility model, the bottom end of the lead screw 3004 is rotatably connected to the inner bottom end of the vertical groove 3002, providing a stable support point for the lead screw, ensuring that the lead screw will not move axially during rotational transmission, ensuring that the slider 3003 rises and falls smoothly along the vertical groove 3002, thereby making the movement of the measuring device 400 more stable and reliable, and avoiding the impact of the instability of the lead screw on the measurement accuracy.
[0034] In one embodiment of this utility model, the propulsion mechanism 500 further includes a hydraulic cylinder 5001. The output end of the hydraulic cylinder 5001 passes through the side plate 200 and is connected to a fixed seat 5003. One side of the fixed seat 5003 is connected to the outer wall of the three-jaw chuck 600. Driven by the hydraulic cylinder 5001, its output end is connected to the three-jaw chuck 600 through the fixed seat 5003, providing stable and large thrust. The hydraulic cylinder 5001 can quickly and smoothly push the three-jaw chuck 600 closer to or away from the docking shaft 700, realizing precise installation and disassembly of the clutch.
[0035] As one embodiment of this utility model, furthermore, limiting rods 5002 are respectively installed on both sides of the fixed base 5003.

[0036] As one embodiment of this utility model, the base frame 100 further includes a base plate 1001, with fixing bolts 1003 inserted at its corners.

[0037] As an embodiment of this utility model, furthermore, support feet 1002 are installed on both sides of the bottom surface of the base plate 1001, which can support the measuring device and keep the base frame at a certain distance from the ground. On the one hand, it can prevent ground moisture and debris from corroding the base frame and protect the bottom components of the device; on the other hand, it can adjust the level of the device so that the measuring device can remain stable in different ground environments and ensure that the device will not shake due to uneven ground during the measurement process, thus providing a stable foundation for accurately measuring the torque of the motorcycle clutch.
[0038] Specifically, the working principle of this motorcycle clutch torque measuring device is as follows: First, the device's level is adjusted and stabilized using the support feet 1002 on the bottom surface of the base plate 1001 to prevent ground moisture from corroding the base frame 100. Next, according to the motorcycle clutch specifications, the motor 3005 on the top surface of the vertical plate 3001 is activated. The motor 3005 drives the lead screw 3004 to rotate, causing the slider 3003, threadedly connected to the lead screw 3004, to slide within the vertical groove 3002. This allows the height of the connecting seat 4002 and the torque sensor 4001 to be adjusted via screws on the slider 3003, aligning the docking shaft 700 with the clutch shaft. Then, the hydraulic cylinder 5001 of the side plate 200's push mechanism 500 is activated, pushing the fixed seat 5003 and the connected three-jaw chuck 600 along the limit rod 5002 towards the docking shaft 700. The three-jaw chuck 600 precisely fixes the clutch, ensuring a reliable connection with the docking shaft 700. During clutch operation, the torque sensor 4001 senses the transmitted torque through the docking shaft 700 and transmits the data to the measuring device 400 for analysis and processing, thereby achieving accurate measurement of the motorcycle clutch torque. Throughout the process, the base plate 1001 is firmly connected to the side plate 200 and the upright plate 3001 via fixing bolts 1003, ensuring the stability of the device structure. The bottom end of the lead screw 3004 is rotatably connected to the vertical groove 3002 to ensure the smooth lifting and lowering of the measuring device 400. The limit rod 5002 prevents the propulsion mechanism 500 from deviating, all of which together ensure measurement accuracy and reliability.
