Description

Technical Field

[0001] The utility model relates to the technical field of clutch release bearing testing equipment, and more specifically, to a clutch release bearing test equipment. Background Art

[0002] The clutch release bearing is installed between the clutch and the transmission. The release bearing seat is loosely sleeved on the tubular extension of the first shaft bearing cover of the transmission. The clutch release bearing is an important part of an automobile. Before mass production of the release bearing, a test device needs to be used to detect its service life. As an important parameter, the durability of the release bearing needs to be tested.

[0003] The existing published number is CN107421743A, and the name is a durability test device for a hydraulic release bearing, including a base. Four support frames are symmetrically arranged on the base. A fixed table is jointly arranged on the four support frames. A release bearing is arranged on the fixed table. Two first grooves and a second groove are opened on the upper surface of the fixed table. Two ball screws are symmetrically arranged in the first groove. A belt pulley is sleeved on the ball screw. A transmission belt is jointly sleeved on the two belt pulleys. The upper end of one of the ball screws is connected to a first motor arranged on the inner wall of the first groove. A first moving block is jointly sleeved on the two ball screws. The moving plate moves downward by the teeth meshing with the incomplete gear. Then, the second moving block moves downward on the third slide rail, and drives the bidirectional rack downward through the fixed rod. Then, the two sector gears meshing with the bidirectional rack both rotate in a direction away from the bidirectional rack, and drive the inner ring fixing block to rotate through the second connecting rod, so that the inner ring fixing block is tightly attached to the inner side wall of the bearing. Then, the second motor is turned on. The second motor drives the inner ring of the release bearing to rotate through the rotating rod. The first bevel gear rotates, and then the meshing second bevel gear rotates, and drives the counter to count through the second rotating shaft.

[0004] However, for the above clutch release bearing detection device, the service durability of the release bearing can only be tested by the number of turns of rotation. However, as an important part of the release bearing, the service durability of the fork of the release bearing is also an important index. The above release bearing detection lacks a detection component for the service durability of the fork, which affects the versatility of the release bearing detection. Summary of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-4, a clutch release bearing test device, comprising a support member 1 and a test member 2. The support member 1 includes a support frame 11. A fixing nail 111 is vertically threadedly penetrated and installed on the bottom surface of the support frame 11, and a slide bar 12 is horizontally fixed on the top surface of the support frame 11. The test member 2 includes a slider 21. The slider 21 is horizontally slidably installed on the slide bar 12, and a rotating plate 22 is vertically fixed on the top surface of the slider 21. A fixed shell cylinder 23 is horizontally fixed on one side of the rotating plate 22, and a drive shaft 24 is horizontally penetrated and installed in the rotating plate 22. A release bearing 28 is installed in the fixed shell cylinder 23, and the inner ring of the release bearing 28 is fixedly connected to the drive shaft 24. A fork 281 is fixed on the release bearing 28. A hole plate 14 is vertically fixed at the end of the slide bar 12, and a pull rod 15 is horizontally slidably penetrated and installed on the hole plate 14. One end of the pull rod 15 is vertically fixed with a pull bar 151, and the pull bar 151 is vertically clamped on the fork 281. An eccentric wheel 17 is rotatably connected to the support frame 11, and a traction rod 16 is rotatably connected to the eccentric shaft of the eccentric wheel 17, and the other end of the traction rod 16 is rotatably connected to the other end of the pull rod 15. In use, the inner ring of the release bearing 28 is sleeved on the drive shaft 24, and then the outer ring of the release bearing 28 is fixed in the fixed shell cylinder 23. The rotation of the drive shaft 24 drives the rotation of the release bearing 28 to conduct a durability rotation test on the release bearing 28. Then, the eccentric wheel 17 rotates on the support frame 11, driving the traction rod 16 to deflect on the eccentric wheel 17. Then, the traction rod 16 pulls the pull rod 15 on the hole plate 14 to slide on the hole plate 14, thereby pulling the pull bar 151 to be vertically clamped on the fork 281 of the release bearing 28, pulling the slider 21 that fixes the release bearing 28 to slide on the slide bar 12. When sliding, the slider 21 squeezes the spring 13 to deform. Then, when the pull bar 151 no longer squeezes the fork 281 of the release bearing 28, the slider 21 is supported by the deformation force of the squeezed spring 13 on the slide bar 12, pushing the slider 21 to translate on the slide bar 12, thereby reciprocally pulling the fork 281 to conduct a fatigue test on the fork 281 of the release bearing 28. When detecting the release bearing, a durability detection component for the use of the fork is set, expanding the versatility of the release bearing detection.

[0028] Refer to Figure 4, a spring 13 is horizontally fixed on the support frame 11, and the other end of the spring 13 is fixed on the slider 21. A pulling motor 18 is horizontally fixed on the support frame 11, and the output end of the pulling motor 18 is fixed on the rotating rod of the eccentric wheel 17. During use, the pulling motor 18 is started to drive the eccentric wheel 17 to rotate, driving the traction rod 16 to deflect on the eccentric wheel 17, and then the traction rod 16 pulls the pull rod 15 on the orifice plate 14 to slide on the orifice plate 14, so as to pull the pull bar 151 to be vertically clamped on the fork 281 of the release bearing 28, and pull the slider 21 fixing the release bearing 28 to slide on the slide bar 12. When sliding, the slider 21 squeezes the spring 13 to deform. Then when the pull bar 151 no longer squeezes the fork 281 of the release bearing 28, the slider 21 is supported on the slide bar 12 by the deformation force of squeezing the spring 13, pushing the slider 21 to translate on the slide bar 12, so as to reciprocally pull the fork 281 to conduct a fatigue test on the fork 281 of the release bearing 28.

[0029] Refer to Figure 3 , a rotating plate 22 is vertically fixed on one side of the slider 21, and a driving motor 25 is horizontally fixed on the rotating plate 22. A counter 26 is installed at the output end of the driving motor 25, and the counter 26 is fixedly connected to the end of the driving shaft 24. During use, the driving motor 25 rotates to drive the counter 26 to rotate. The counter 26 is fixedly connected to the end of the driving shaft 24 to conduct an endurance test on the release bearing 28, and the counter 26 is used for counting the number of rotations.

[0030] Refer to Figure 3 , a fixed shell 27 is horizontally fixed at the end of the fixed shell cylinder 23, and an extrusion stud 271 is threadedly penetrated and installed on the outer circumferential surface of the fixed shell 27, and a pressing block 272 is fixed at the end of the extrusion stud 271. A thread groove is formed on the outer circumferential surface of the driving shaft 24. A locking bolt 282 is vertically threadedly penetrated and installed on the inner ring of the release bearing 28, and the locking bolt 282 is threadedly assembled in the thread groove of the driving shaft 24. A threaded hole is vertically penetrated and opened on the bottom surface of the support frame 11, and a fixing nail 111 is vertically threadedly penetrated and installed in the threaded hole of the support frame 11. During use, the release bearing 28 is inserted into the fixed shell 27, and the extrusion stud 271 is rotated to squeeze the release bearing 28 to be stable in the fixed shell 27. The inner ring of the release bearing 28 is fixedly connected to the driving shaft 24 through the locking bolt 282, effectively keeping the inner ring of the driving shaft 24 driving the release bearing 28 to rotate.

[0031] During use, the inner ring of the release bearing 28 is sleeved on the drive shaft 24, and then the outer ring of the release bearing 28 is fixed in the fixed housing cylinder 23. The rotation of the drive shaft 24 drives the rotation of the release bearing 28 to conduct a durability rotation test on the release bearing 28. Then, the eccentric wheel 17 rotates on the support frame 11, driving the traction rod 16 to deflect on the eccentric wheel 17. Then, the traction rod 16 pulls the pull rod 15 on the orifice plate 14 to slide on the orifice plate 14, thereby pulling the pull bar 151 to be vertically clamped on the fork 281 of the release bearing 28, and pulling the slider 21 that fixes the release bearing 28 to slide on the slide bar 12. When sliding, the slider 21 squeezes the spring 13 to deform. Then, when the pull bar 151 no longer presses the fork 281 of the release bearing 28, the slider 21 is supported on the slide bar 12 by the deformation force of the squeezed spring 13, pushing the slider 21 to translate on the slide bar 12, thereby reciprocally pulling the fork 281 to conduct a fatigue test on the fork 281 of the release bearing 28.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
