Description

Technical Field

[0001] The invention belongs to the technical field of clutch testing, and in particular relates to a wet clutch testing tool. Background Art

[0002] The operation of the wet clutch is closely related to the vehicle's starting jitter behavior. For example, wear of the clutch's main components, such as the friction plate, pressure plate, and release bearing, abnormalities in the lubrication system, and abnormal clutch engagement processes may all cause vehicle starting jitter. Therefore, testing the clutch and studying the relationship between the clutch's working state and vehicle starting jitter are of guiding significance for suppressing vehicle jitter and improving vehicle driving stability. When conducting clutch testing, existing clutch testing devices usually require the clutch to be removed from the gearbox, so that the clutch is not in its actual working state during the test. The test results obtained by this method will differ from the actual usage state, affecting the test simulation, so it is necessary to make improvements. Summary of the Invention

DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] The present application embodiment provides a wet clutch test tool, such as Figure 1-Figure 3 As shown, it includes a support assembly, a hydraulic component 17, a test assembly 2, etc.

[0032] Specifically, the support assembly 1 is a pair, each including a base body 11 and a pair of mutually symmetrical support plates 12 hinged on the base body 11, the axis of the hinge of the support plates 12 is parallel to the width direction of the base body 11, and the relative support plates 12 form a V-shaped structure, so that the gearbox 3 is placed between the two support plates 12, and the gearbox 3 can be fixed by the two support plates 12, and the opposite inner sides of the support plates 12 are rotated from one end to the other end of the hinge portion close to the support plate 12, and are connected with a transverse guide roller 15 and a vertical guide roller 13, and a transition portion 14 is provided between the transverse guide roller 15 and the vertical guide roller 13, and the vertical guide roller 13 is a shuttle-shaped structure, and the rotation axis of the vertical guide roller 13 is parallel to the width direction of the support plate 12, and the width direction of the support plate 12 is perpendicular to the axis of its hinge, and the rotation axis of the transverse guide roller 15 Parallel to the length direction of the support plate 12, the side of the transition portion 14 away from the support plate 12 is an arc-shaped surface protruding from the transverse guide roller 15 and the vertical guide roller 13. The vertical guide roller 13 and the transition portion 14 are both provided in multiples along the length direction of the support plate 12, and the transverse guide roller 15 is provided in multiples along the width direction of the support plate 12. The vertical guide roller 13 is used to adjust the position of the gearbox 3 along the length direction of the support plate 12, and the transverse guide roller 15 is used to reduce the friction between the gearbox 3 and the support plate 12 when the gearbox 3 moves downward. There are two pairs of hydraulic components 17, and the fixed ends of the two pairs of hydraulic components 17 are respectively hinged to a pair of base bodies 11, and the telescopic ends of the hydraulic components 17 are respectively hinged to the outside of the two pairs of support plates 12. The test assembly 2 includes a driving component and a driven component, and a pair of support assemblies 1 are provided between the driving component and the driven component. During the test, the gearbox 3 equipped with a clutch is rotatably connected between the driving component and the driven component.

[0033] In actual use, the hydraulic components 17 are first used to adjust the angle of the support plates 12 of each support assembly 1 so that the gearbox 3 can be placed between the vertical guide rollers 13. The gearbox 3 is then pushed onto the vertical guide rollers 13 from the outward end of the support assembly. The hydraulic components 17 are then used to increase the angle between the support plates 12. During this process, the gearbox 3 slides onto the transition portion 14. As the angle between the support plates 12 further increases, the gearbox 3 moves onto the transverse guide rollers 15. Under the action of the vertical guide rollers 13, the support plates 12 can both support the gearbox 3 and transport the gearbox 3 along the length of the support plates 12. That is, the gearbox 3 can be placed in two ways. One is to suspend the gearbox 3 and place it between the two support plates 12 from above the support plate 12. The other is to send the gearbox 3 between the two support plates 12 from one end of the support assembly 1. Then, the gearbox 3 is pushed to move, and the gearbox 3 contacts the vertical guide roller 13. Finally, the two support plates 12 are gradually separated. After adjusting the position of the gearbox 3 between the two support plates 12, the input shaft of the clutch is connected to the driving component, and the output end of the gearbox 3 is connected to the driven component for testing. When testing the clutch in this way, the clutch is installed on the gearbox 3. This makes the clutch in actual working state during testing, improves the test simulation of the clutch, and at the same time, can also observe the influence of the clutch on the working state of the gearbox 3. By setting the height of the two support assemblies 1 and the angle between the support plates 12 of each support assembly 1, gearboxes 3 of different shapes and sizes can be fixed.

[0034] For details, see Figure 3 The vertical guide roller 13 is in a shuttle shape. The shuttle-shaped curved surface structure can reduce the vertical force component when the vertical guide roller 13 supports the gearbox 3, reduce the wear of the vertical guide roller 13, and improve the support effect on the gearbox 3. Specifically, the transition portion 14 is made of a flexible material, such as rubber. When the gearbox 3 moves to the transition portion 14, the gearbox 3 first abuts against the transition portion 14, so that the gearbox 3 can avoid the end of the vertical guide roller 13 close to the base 11, avoiding wear on the lower half of the vertical guide roller 13. As the support plate 12 continues to rotate outward, the gearbox 3 moves toward the middle part of the transition portion 14 where the protrusion is the largest, and finally allows the gearbox 3 to gradually fall onto the transverse guide roller 15, avoiding the risk of wear caused by collision between the gearbox 3 and the transverse guide roller 15.

[0035] Preferably, see Figure 2 、 Figure 4The support assembly 1 also includes a lifting component 19, which is used to lift the seat body 11. Specifically, the lifting component 19 is a hydraulic cylinder, which is arranged at the bottom of the seat body 11, and the telescopic end of the hydraulic cylinder is connected to the bottom of the seat body 11. By lifting the support assembly 1 by the lifting component 19, the horizontal heights of the two support assemblies 1 can be adjusted as needed to adapt to the structure of the gearbox 3. For example, for some gearboxes 3, the structure may be one end larger than the other end. In this case, the horizontal height of one of the support assemblies 1 can be raised and the horizontal height of the other support assembly 1 can be lowered. In some embodiments, the seat body 11 includes a fixed seat 111 and a pair of movable seats 112. The pair of movable seats 112 are both slidably connected to the fixed seat 111 along the length direction of the support plate 12. The two pairs of support plates 12 are respectively hinged to the two pairs of movable seats 112, and the fixed ends of the two pairs of hydraulic components 17 are respectively hinged to the two pairs of movable seats 112. Specifically, the fixed seat 111 can be provided with a guide rail, and the movable seat 112 is slidably connected to the guide rail, so that the movable seat 112 can move relative to the fixed seat 111. The fixed seat 111 can also be provided with a drive structure to drive the movable seat 112 to move. Furthermore, the fixed seat 111 can be provided with a locking structure to unlock or lock the movable seat 112. The drive structure and locking structure can be selected from existing technologies and will not be described in detail here. Since the position of the movable seat 112 relative to the fixed seat 111 is adjustable, the distance between the two support plates 12 can be adjusted, so that the support assembly 1 can adapt to gearboxes 3 of different sizes.

[0036] For details, see Figure 2 The driving component includes a driving seat 21 and a motor 22. The driving seat 21 is rotatably connected to the seat body 11 of the support assembly 1 close to the driving component. The motor 22 is arranged on the driving seat 21. The output end of the motor 22 is provided with a driving shaft sleeve 23; the driven component includes a driven seat 24 and a driven shaft sleeve 25. The driven seat 24 is rotatably connected to the seat body 11 of the support assembly 1 close to the driven component. The driven shaft sleeve 25 is rotatably provided on the driven seat 24. The driving seat 21 and the driven seat 24 are respectively provided with a detection component 26.

[0037] The driver seat 21 and the driven seat 24 are rotatably mounted on the corresponding seat body 11, so that when removing or placing the gearbox 3, the driver seat 21 or the driven seat 24 can be rotated to increase the operating space. The driver seat 21 and the driven seat 24 can be provided with locking structures, so that the driver seat 21 and the driven seat 24 can be respectively unlocked or locked. In the unlocked state, the driver seat 21 or the driven seat 24 can rotate relative to the corresponding seat body 11. In the locked state, they cannot rotate relative to the corresponding seat body 11. Similarly, the locking structure of the driver seat 21 and the driven seat 24 can be selected from existing structures. The technical solution of this application does not improve this part, so it will not be described in detail.

[0038] The motor 22 can be adjusted in position on the drive seat 21 so that the drive sleeve 23 provided on the motor 22 can be aligned with the input shaft of the clutch, and the input shaft of the clutch can be inserted into the drive sleeve 23. When the output end of the motor 22 rotates, the input end of the clutch can rotate.

[0039] The driven sleeve 25 can also be adjustably arranged on the driven seat 24 so that the output end of the gearbox 3 can be inserted into the driven sleeve 25 . When the input end of the clutch rotates, the driven sleeve 25 can be driven to rotate.

[0040] A circumferential anti-slip structure may be provided between the drive sleeve 23 and the input end of the clutch. For example, a key may be provided between the input end of the clutch and the drive sleeve 23 to prevent relative sliding between the input end of the clutch and the drive sleeve 23. Similarly, a circumferential anti-slip structure may also be provided between the driven sleeve 25 and the output end of the gearbox 3.

[0041] In order to cope with the possible vibration of the gearbox 3, a vibration reduction structure can be provided between the motor 22 and the driving seat 21, and between the driven shaft sleeve 25 and the driven seat 24.

[0042] The detection component 26 is used to detect the status of the drive sleeve 23 and the driven sleeve 25, thereby determining the status of the clutch input and the transmission output, and providing feedback data for the clutch test. For example, the detection component 26 may include a speed sensor for measuring the rotational speed of the drive sleeve 23 and the driven sleeve 25. The detection component 26 may also include a displacement sensor. When the transmission 3 vibrates, the drive sleeve 23 may vibrate relative to the drive seat 21, and the driven sleeve 25 may vibrate relative to the driven seat 24. The displacement sensor can be used to measure the vibration displacement of the drive sleeve 23 and the driven sleeve 25.

[0043] The displacement sensor and velocity sensor are electrically connected to a host computer for control of their operation. The host computer can be a computer. The specific circuitry, control code, and operating principles of the displacement sensor and velocity sensor controlled by the computer are well known to those skilled in the art and will not be described in detail here. Furthermore, the specific installation locations of the displacement sensor and velocity sensor can be set as needed and do not need to be fixed, as long as they meet the measurement objectives.

[0044] Preferably, see Figure 4The support plates 12 are each hingedly connected to a cover portion 16 at one end away from the hinge portion. A pusher 18 is provided below the cover portion 16 for rotating the cover portion 16. The cover portion 16 is used to secure the gearbox 3. Specifically, when the gearbox 3 is positioned between the two support plates 12, the cover portion 16 is rotated so that the cover portion 16 covers the gearbox 3, thereby securely securing the gearbox 3 between the two support plates 12.

[0045] For details, see Figure 5-Figure 7 The pushing component 18 includes a mounting portion 181 and a pushing portion 182. The mounting portion 181 is slidably connected to the outer side of the support plate 12 along the width direction of the support plate 12. The telescopic end circumference of the hydraulic component 17 abuts the bottom of the mounting portion 181. The pushing portion 182 is provided on the mounting portion 181, and the top of the pushing portion 182 abuts the side of the cover portion 16 close to the support plate 12. When the telescopic end of the hydraulic component 17 contracts, the support plates 12 rotate in a direction away from each other, and the telescopic end circumference of the hydraulic component 17 pushes the mounting portion 181 to slide upward along the length direction of the vertical guide roller 13, so that the pushing portion 182 pushes the cover portion 16, so that the cover portion 16 can rotate until it abuts and presses the gearbox 3 on the transverse guide roller 15. More specifically, a torsion spring can be provided at the hinge between the cover portion 16 and the support plate 12, so that the portion of the cover portion 16 between the two support plates 12 has a tendency to rotate upward.

[0046] After the covering portion 16 is provided, the transition portion 14 can also increase the fixing effect of the covering portion 16 on the gearbox 3, that is, compared with the case where the transition portion 14 is not provided, under the action of the transition portion 14, the support plate 12 needs to rotate at a larger angle to enable the gearbox 3 to move to the transverse guide roller 15, thereby increasing the stroke of the mounting portion 181, thereby making the rotation stroke of the covering portion 16 larger or making the pressure generated by the covering portion 16 on the gearbox 3 greater.

[0047] Preferably, see Figure 5 、 Figure 6 (In order to illustrate the internal structure of the mounting portion 181, Figure 5 and Figure 6 (The state shown in FIG1 shows the side walls of the mounting portion 181 hidden, with only the bottom wall 189 visible.) The pushing portion 182 is slidably connected to the mounting portion 181 along the width direction of the support plate 12. The mounting portion 181 and the pushing portion 182 are connected by a first elastic member 183. Specifically, the first elastic member 183 can be a spring. Since the outer contour of the gearbox 3 may be irregular, the first elastic member 183 can compensate for the travel of the pushing portion 182, ensuring that the pushing portion 182 can push the covering portion 16 against the gearbox 3.

[0048] For details, see Figure 7The mounting portion 181 is a cylinder with a receiving cavity 1814 at the top, the pushing portion 182 is slidably disposed in the receiving cavity 1814, and the two ends of the first elastic member 183 are respectively connected to the bottom wall 189 of the receiving cavity 1814 and the bottom of the pushing portion 182.

[0049] Preferably, see Figure 5 、 Figure 6 、 Figure 8 , an arm 184 is provided on both sides of the pushing portion 182, one end of the two arms 184 is connected to a connecting portion 187, a strip-shaped through-slot 185 is provided on the arm 184, the length direction of the strip-shaped through-slot 185 is perpendicular to the length direction of the pushing portion 182, and a pair of rotating shafts 186 are vertically provided on the circumference of the pushing portion 182, the pair of rotating shafts 186 are passed through the pair of strip-shaped through-slots 185, and the rotating shafts 186 are at one end of the strip-shaped through-slot 185 away from the connecting portion 187; the bottom wall 189 of the accommodating cavity 1814 of the mounting portion 181 is fixedly connected to a guide rod 188 parallel to its axial direction, the cross-section of the guide rod 188 is rectangular, and the top of the connecting portion 187 is facing downward A rectangular through hole 1813 is provided, and the guide rod 188 is passed through the through hole 1813. When the side of the guide rod 188 close to the pushing portion 182 abuts against the side of the through hole 1813 close to the pushing portion 182, there is a preset distance between the side of the pushing portion 182 away from the pushing portion 182 and the side of the through hole 1813 away from the pushing portion 182. When the first elastic member 183 is in a natural state, the support arm 184 is perpendicular to the guide rod 188. When the first elastic member 183 performs a contraction stroke, the support arm 184 is inclined relative to the guide rod 188, and the top of the side of the through hole 1813 away from the pushing portion 182 abuts against the guide rod 188.

[0050] When the control cover portion 16 presses the gearbox 3, and the peripheral side of the hydraulic component 17 continues to push the pushing portion 182 toward the mounting portion 181, because the transmission is through the hydraulic component 17, the mounting portion 181 moves slowly, and the friction between the side wall of the through hole 1813 of the connecting portion 187 and the guide rod 188 is relatively small. Even if the support arm 184 rotates to a tilted state, the mounting portion 181 can move relative to the pushing portion 182, compressing the first elastic member 183, and under the action of the through hole 1813 of the connecting portion 187, the pushing portion 182 moves along the guide rod 188, so that the matching portion and the connecting portion 187 can increase the matching accuracy and connection strength of the mounting portion 181 and the pushing portion 182.

[0051] During the test, the gearbox 3 may vibrate, and at this time, the gearbox 3 will exert an instantaneous force on the cover portion 16 to rotate it out from between the two support plates 12. Because the rotating shaft 186 is arranged on the side of the strip-shaped through-slot 185 away from the guide rod 188, the support arm 184 has a tendency to rotate upward relative to the guide rod 188, and the through-hole 1813 then rotates upward relative to the guide rod 188. At this time, due to the clearance fit between the through-hole 1813 of the connecting portion 187 and the guide rod 188, and the large instantaneous force transmitted from the covering portion to the pushing portion 182, the side wall of the through-hole 1813 will exert a large component force on the guide rod in the horizontal direction, causing the side wall of the through-hole 1813 to be subjected to a large friction force, thereby preventing the connecting portion 187 from moving relative to the guide rod, blocking the pushing portion 182, and thus fixing the cover portion 16 and improving the fixing effect of the covering portion 16 on the gearbox 3.

[0052] Preferably, see Figure 8 、 Figure 9 The other side of the pushing portion 182 and the wall of the through hole 1813 away from the pushing portion 182 are connected to the abutment portion 1811 through the second elastic member 1815, which is used to make the guide rod 188 receive the push of the abutment portion 1811 when the first elastic member 183 is in the natural state, so that the support arm 184 is in a state perpendicular to the guide rod 188.

[0053] Preferably, see Figure 8 、 Figure 9 The top of the through hole 1813, away from the pushing portion 182, is formed with an inclined surface 1812 that slopes downward toward the guide rod 188. When the first elastic member 183 undergoes a contraction stroke, the inclined surface 1812 abuts the guide rod 188. When the connecting portion 187 rotates upward relative to the guide rod 188, the inclined surface 1812 abuts the guide rod 188, increasing the contact area between the inner wall of the through hole 1813 and the guide rod 188. This not only increases the friction between the through hole 1813 and the guide rod 188, but also reduces wear on the inner wall of the through hole 1813.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to be the only one or to limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
