Description

Technical Field

[0001] This utility model belongs to the field of clutch release bearing testing technology, specifically a device for testing the durability of clutch release bearings. Background Technology

[0002] The clutch release bearing is installed between the clutch and the transmission. Its working principle involves using a return spring to keep the release bearing shoulder at the main release fork, while also allowing it to retract to its final position, approximately 3-4mm from the end. This ensures smooth clutch engagement. The clutch release bearing is a crucial component in automobiles. Since the clutch pressure plate, release lever, and engine crankshaft rotate synchronously, its release fork can only move axially along the clutch output shaft. Installing a clutch release bearing makes clutch operation smoother, reduces wear, and extends clutch life. To ensure the clutch release bearing's performance meets the demands of prolonged rotation, durability testing is necessary.

[0003] In existing technologies, when testing clutch release bearings, the release bearings need to be fixed. However, when fixing them, only a single size release bearing can be fixed, which can only match a specific model. The compatibility is extremely poor, and it is impossible to test release bearings of different brands and models.

[0004] Therefore, this utility model provides a device for testing the durability of a clutch release bearing. Utility Model Content

[0005] To overcome the shortcomings of existing technology and solve the problem that when testing clutch release bearings, the release bearings need to be fixed, but the fixing can only be done on a single size release bearing, which can only match a specific model and has extremely poor compatibility, making it impossible to test release bearings of different brands and models.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A clutch release bearing durability testing device of this utility model includes a base plate, and a testing mechanism is provided on the top of the base plate. The testing mechanism includes: The dragging mechanism includes a dragging motor fixedly connected to the top of the base plate, a rotating shaft at the output end of the dragging motor, a fixed disk fixedly connected to the end of the rotating shaft away from the motor, a set of first sliding slots on the fixed disk, a first sliding block slidably connected in the first sliding slots, a fixed rod fixedly connected to the side wall of the first sliding block, and an adjustment component for adjusting the set of first sliding blocks on the fixed disk. A fixing component is installed on the top of the base plate to fix the outer ring of the bearing.

[0008] Preferably, a gear disk is fixedly connected to the rotating ring, and the gear disk meshes with a gear. A set of arc-shaped holes are opened on the gear disk. A first circular block is fixedly connected to the side of the first sliding block away from the fixed rod, and the first circular block is movably connected in the arc-shaped hole.

[0009] Preferably, the fixing component includes a fixing plate fixed to the top of the base plate, a pair of second sliding slots are provided on the fixing plate, a second sliding block is slidably connected in the second sliding slot, a clamping block is fixed to the side wall of the second sliding block, and a second circular block is fixed to the other side of the second sliding block.

[0013] 2. The clutch release bearing durability testing device of this utility model can avoid V-block displacement through the guiding action of the guide rod and L-shaped rod, ensure the stability of the clamping force of the clamping block on the ring, and prevent bearing displacement during the testing process.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown, an embodiment of the present invention discloses a clutch release bearing durability testing device, comprising a base plate 1, a testing mechanism on the top of the base plate 1, the testing mechanism comprising: a dragging mechanism, including a dragging motor 2 fixedly connected to the top of the base plate 1, a power source for the dragging mechanism, outputting rotational power, a rotating shaft 3 at the output end of the dragging motor 2, a fixed disk 4 fixedly connected to the end of the rotating shaft 3 away from the motor, a set of first sliding grooves 5 opened on the fixed disk 4, a first sliding block 6 slidably connected in the first sliding grooves 5, movable along the grooves to adjust the position of a fixing rod 7, a fixing rod 7 fixedly connected to the side wall of the first sliding block 6 for fixing the bearing inner ring and driving the inner ring to rotate, an adjusting component for adjusting the set of first sliding blocks 6 on the fixed disk 4 to adjust the spacing of the first sliding blocks 6 to adapt to bearings of different specifications; and a fixing component, set on the top of the base plate 1 for fixing the bearing outer ring.

[0018] The adjustment assembly includes a fixed plate 4 with a concave frame 8 fixed to the side wall, a stepper motor 9 fixed to the inner wall of the concave frame 8, which is the power source of the adjustment assembly and outputs precise rotational power. The output end of the stepper motor 9 is provided with a drive rod 10, and a gear 11 is fixed to the drive rod 10. An annular groove 12 is opened on the side wall of the fixed plate 4, and a rotating ring 13 is rotatably connected in the annular groove 12.

[0019] A gear 14 is fixedly connected to the rotating ring 13, and the gear 14 is meshed with the gear 11. Through meshing transmission, the gear 14 is driven to rotate. A set of arc-shaped holes 15 are provided on the gear 14 to provide a moving path for the first circular block 16, converting the rotation of the gear 14 into the linear movement of the first sliding block 6. The first circular block 16 is fixedly connected to the side of the first sliding block 6 away from the fixed rod 7, and the first circular block 16 is movably connected in the arc-shaped hole 15.

[0020] During operation, the spacing of the fixing rod 7 can be flexibly adjusted by adjusting the stepper motor 9, gear 11, and gear plate 14 of the adjustment component to adapt to inner rings with different inner diameters; it can also be used in conjunction with the fixing component to fix the outer ring of the bearing, thereby solving the problem in the prior art that when testing the clutch release bearing, the release bearing needs to be fixed, but when fixing it, it can only fix a single size release bearing, which can only match a specific model, has extremely poor adaptability, and cannot test release bearings of different brands and models.

[0021] The fixing assembly includes a fixing plate 17 fixed to the top of the base plate 1, which supports and fixes related components and provides stable support. A pair of second sliding slots 18 are provided on the fixing plate 17 to provide a sliding track for the second sliding block 19. The second sliding block 19 is slidably connected in the second sliding slots 18. A clamping block 20 is fixed to the side wall of the second sliding block 19, which directly contacts and clamps the outer ring of the bearing. A second circular block 21 is fixed to the other side of the second sliding block 19.

[0022] An electric actuator 22 is fixedly connected to the top of the base plate 1. A V-shaped block 23 is fixedly connected to the telescopic end of the electric actuator 22, which converts the power of the electric actuator 22 into the clamping force of the clamping block 20. A pair of inclined holes 24 are provided on the V-shaped block 23, and a second circular block 21 is slidably connected in the inclined holes 24.

[0023] A pair of guide rods 25 are fixed to the top of the base plate 1. An L-shaped rod 26 is slidably connected to the guide rods 25. The L-shaped rod 26 is fixed vertically to the top of the V-shaped block 23, which restricts the movement direction of the V-shaped block, ensures the stability of the movement, assists in supporting the V-shaped block, and enhances the structural stability.

[0024] During operation, the guide rod 25 and L-shaped rod 26 can prevent the V-block 23 from shifting, ensuring that the clamping force of the clamping block 20 on the ring is stable. The dual stability design can prevent bearing displacement during the test, avoid distortion of test data such as temperature and vibration caused by loose fixing, and improve the accuracy of durability assessment.

[0025] Working principle: When the inner ring diameter of the bearing to be tested is different, the stepper motor 9 of the adjustment component is started. The stepper motor 9 drives the drive rod 10 and the gear 11 to rotate. The gear 11 meshes with the gear disk 14, which in turn drives the rotating ring 13 to rotate in the annular groove 12 of the fixed disk 4. When the rotating ring 13 rotates, the arc-shaped hole 15 on the gear disk 14 moves synchronously. The arc-shaped hole 15 drives the first sliding block 6 to slide along the first sliding groove 5 of the fixed disk 4 through the first circular block 16. Finally, the fixed rods 7 on each first sliding block 6 move closer to or further away from the center of the circle synchronously. By adjusting the spacing of the fixed rods 7, bearing inner rings with different inner diameters can be adapted to ensure that the inner ring and the fixed rods 7 fit tightly and without loosening.

[0026] After the inner ring of the bearing is fixed, the electric push rod 22 is activated. The telescopic end of the electric push rod 22 drives the V-block 23 to move back and forth along the guide rod 25 (guided by the L-shaped rod 26 to prevent the V-block 23 from shifting). When the V-block 23 moves, the inclined hole 24 on its side wall drives the second sliding block 19 to slide along the second sliding groove 18 of the fixed plate 17 through the second circular block 21. The second sliding blocks 19 on both sides move closer or further away at the same time. By adjusting the distance between the clamping blocks 20 on both sides, it can be adapted to bearing outer rings of different outer diameters to ensure that the clamping blocks 20 can tightly clamp the outer ring and prevent the outer ring from shaking during the test. After the outer ring is fixed, the bearing is in the real working state of "inner ring rotating and outer ring fixed" (consistent with the working mode of the release bearing in automobiles). At this time, temperature, torque and other sensors can be used (such as adding sensors to the fixed rod 7 or clamping blocks 20) to monitor the temperature change, wear, vibration amplitude and other parameters of the bearing during continuous rotation, and then evaluate its durability.
