Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle clutches, in particular to a motorcycle clutch load test bench. Background Art

[0002] The clutch is a crucial component in a motorcycle's power transmission system, responsible for connecting and disconnecting power between the engine and transmission. Traditional motorcycle clutches mostly use mechanical friction clutches, whose internal structure typically consists of multiple alternating friction plates and steel plates. Springs apply pressure to keep these plate-like components in close contact to achieve power transmission. By manipulating a push rod and squeeze plate, the contact and separation of the friction plates and steel plates can be controlled, thereby engaging and disengaging the clutch. To ensure the reliability and performance of motorcycle clutches in actual use, load testing is an essential step. Load testing can simulate the clutch's state under various operating conditions and evaluate its torque transmission capacity, wear resistance, and temperature rise characteristics under different load conditions. Reliable load testing can help engineers identify and improve weak links in clutch design, thereby improving its performance and lifespan.

[0003] Patent publication number CN105987815B discloses a universal motorcycle clutch test bench device, comprising a driving shaft device and a driven shaft device. The driving shaft device comprises a first drive device and a second drive device. The first drive device comprises a drive motor, the motor shaft of which is connected to the driving shaft via a coupling, and the driving shaft is mounted with an inertia flywheel assembly and a drive bearing assembly. The second drive device comprises a reducer mounting seat and a reducer, the low-speed drive shaft of the reducer being mounted with a reducer gear. The driven shaft device comprises a driven shaft, and the driven shaft is mounted with an inertia test flywheel, a magnetic powder brake, a brake mounting bracket, and a driven bearing assembly. The brake mounting bracket is mounted with a test device. The universal motorcycle clutch test bench device of the present invention has high detection accuracy, stable operation, and high reliability, and is suitable for clutch manufacturers to carry out clutch development research and quality control.

[0004] The above-mentioned existing technology can simulate and test the resistance of a motorcycle clutch during different driving processes, and the data measured by the magnetic powder brake tension and pressure sensor and the air pressure butterfly brake tension and pressure sensor can be used to calculate the various performance parameters of the clutch. However, the first drive device and the second drive device in the test bench device will generate heat after continuously driving the clutch to rotate. In order to avoid overheating and damage of the first drive device and the second drive device after a single test or multiple tests, it is necessary to stop and wait. The next test can only be carried out after the first drive device and the second drive device cool down, which affects the test efficiency. In view of this, we propose a motorcycle clutch load test bench. Utility Model Content

[0032] An air flow generating assembly 5 is provided on the top of the U-shaped plate 2. The air flow generating assembly 5 includes a rectangular shell 50 fixedly connected to the top of the U-shaped plate 2.

[0033] An air flow is generated by the fan 52, and the outside air enters the dust collection box 53 from the air inlet 530, and then passes through the first filter plate 54 and the second filter plate 55 in turn, so that the particulate matter in the air is filtered to prevent the fan 52 and the air jet pipe 41 from being blocked. The filtered air enters the circular tube 51 from the circular hole a500, and then enters the two air guide hoses 6 from the three-way pipe, and then enters the strip air guide plate 4 from the air guide hose 6, and finally is ejected from multiple air jet pipes 41, thereby realizing the air cooling effect on the test component 7 and improving the test efficiency.

[0034] In this embodiment, the driving assembly 3 also includes two positioning rods 33 arranged symmetrically in the front and back directions. The left and right ends of the positioning rods 33 are respectively fixedly connected to the left and right sides of the inner wall of the U-shaped plate 2, and the moving block 31 is slidably connected to the outer side of the positioning rods 33 to improve the stability of the moving block 31 when it moves left and right.

When the dust box 53 needs to be cleaned, the staff will rotate the anti-slip rotating block 58 upward to a horizontal state, release the limit on the dust box 53, and then the dust box 53 can be pulled out.

[0040] Furthermore, two handles 57 are provided on the front side of the dust box 53 in a bilaterally symmetrical manner to facilitate the staff in moving and disassembling the dust box 53 .

[0041] When using the motorcycle clutch load test bench of this embodiment, first ensure that the base 1 is properly installed and placed on a stable surface, confirm that all sensors, including the speed sensor, torque sensor, temperature sensor, and pressure sensor, are properly installed and connected to the data acquisition system; install the motorcycle clutch to be tested in a predetermined position on the test assembly 7, ensure that the clutch input shaft and output shaft are aligned with the drive system and the load application system, and fix the clutch; use the control system to set test parameters, including the output speed of the motor, the current of the magnetic powder brake, and the pressure value of the mechanical brake to simulate different working conditions, input the load conditions and working condition parameters to be tested, and record the preset test conditions through the data acquisition system; start the motor to drive the input shaft of the motorcycle clutch to rotate through the coupling to simulate the output of the engine, activate the magnetic powder brake and the mechanical brake according to the set test conditions, and apply the corresponding load to the clutch output shaft by adjusting the current and pressure. The sensor system monitors the performance parameters of the clutch in real time during the test, including the input and output speeds, torque, temperature, and pressure, and the data acquisition system records and transmits this data to the control system; after the load test is completed, the staff removes the motorcycle clutch and then starts the fan 52 and servo motor 32 to work. In operation, air flow is generated by the fan 52, and the outside air enters the dust collection box 53 from the air inlet 530, and then passes through the first filter plate 54 and the second filter plate 55 in sequence, so that the particulate matter in the air is filtered to prevent the fan 52 and the air injection pipe 41 from being blocked. The filtered air enters the circular tube 51 from the circular hole a500, and then enters the two air guide hoses 6 from the three-way pipe, and then enters the strip air guide plate 4 from the air guide hose 6. The servo motor 32 drives the bidirectional screw rod 30 to rotate forward and reverse, so that the bidirectional screw rod 30 drives the two moving blocks 31 to move synchronously relative to each other or in the opposite direction, so that the two moving blocks 31 respectively drive the two strip air guide plates 4 to rotate synchronously. The first filter plate 54 and the second filter plate 55 are removed, and the particulate matter on the filter plates is cleaned to ensure that the air flow system is unobstructed. Through the above-mentioned usage, the motorcycle clutch load test bench can efficiently and accurately evaluate the performance of the clutch under different load conditions, and provide reliable data support for the development, research and quality control of the clutch.
