Description

Technical Field

[0001] The present disclosure relates to the technical field of clutches, and in particular to a clutch life warning device, a clutch and a vehicle. Background Art

[0002] The friction disc of the clutch of a manual transmission vehicle is a consumable. Each semi-clutch process will cause wear to the friction disc, and its thickness will become thinner and thinner. As its thickness decreases, the clamping force applied by the pressure plate will change accordingly. When the thickness wears to a certain extent, the clamping force will decay rapidly. If the clamping force is insufficient, the torque transmission performance will decrease rapidly. If it is not replaced in time, the clutch will slip, which can burn the clutch in a short time. The high-temperature smoke generated in the process will spread to the entire flywheel housing. In many cases, the crankshaft oil seal, gearbox oil seal and other seals, together with the flywheel end face, will be damaged together, causing great maintenance costs and economic losses. Therefore, the clutch should be replaced in time before slipping. Because the clutch is enclosed in the flywheel housing, it is invisible and its status cannot be directly observed. Due to differences in operating conditions and driver habits, it is difficult to provide a reasonable replacement cycle or mileage for the clutch. Therefore, some measures are needed to detect the wear of the clutch, provide early warning, and avoid the problem of untimely clutch replacement. Summary of the invention

[0014] Through the above technical scheme, in the clutch life warning device provided by the present invention, the sleeve is connected to the driving mechanism of the clutch, so that the driving mechanism drives the sleeve to move along the shaft sleeve, and the sleeve is pressed against the diaphragm spring. When the friction disc of the clutch is worn and thinned, in order to ensure the pressing force of the friction disc, the outer ring of the diaphragm spring will be pressed in the direction of the flying disc, and at the same time, the center of the diaphragm spring moves in the direction away from the flying disc, forcing the initial position of the sleeve to move in the direction away from the flying disc, causing the initial position to retreat.

[0018] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0019] In the present disclosure, unless otherwise stated, "inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0020] The present disclosure provides a clutch life warning device, comprising: a sleeve 2, which is used to be sleeved on a transmission shaft 1 of a clutch; a sleeve 3, which is slidably arranged on the sleeve 2 and is used to be connected to a driving mechanism 5 for driving the clutch to operate, and one end of the sleeve 3 is used to abut against a diaphragm spring 10 connected to a clutch pressure plate 9; and a resistance mechanism 4, which is telescopically arranged on one of the sleeve 3 or the sleeve 2; a pit 21 is arranged on the other of the sleeve 3 or the sleeve 2, and the pit 21 arranged on the sleeve 2 or the resistance mechanism 4 is arranged at a preset warning position, so that when the sleeve 3 moves to the warning position, the resistance mechanism 4 extends into the pit 21, so that when the sleeve 3 moves to the warning position, resistance is generated when the sleeve 3 moves toward the direction of the clutch pressure plate 9 again.

[0021] Through the above technical scheme, in the clutch life warning device provided by the present disclosure, the clutch includes a flying disc 6, a transmission shaft 1, a clutch pressure plate 9, a friction plate 8, a clutch cover 11, a diaphragm spring 10, a sleeve 3 and a driving mechanism 5, the driving mechanism 5 includes a clutch pedal 51, a master cylinder 52, an oil pipe 53, a slave cylinder 54 and a shift fork 12, the flying disc 6 is connected to the engine, the clutch pressure plate 9 is installed on the transmission shaft 1 through a spline hub 7 and rotates with the transmission shaft 1, the transmission shaft 1 is connected to the vehicle's gearbox, the clutch cover 11 is installed on the clutch pressure plate 9, the transmission shaft 1 is connected to the transmission shaft 1, and the clutch cover 11 is installed on the clutch pressure plate 9. The flying disc 6 is not connected, the friction disc 8 is arranged on the side of the clutch pressure plate 9 close to the flying disc 6, the friction disc 8 contacts the flying disc 6 to transmit the power of the engine to the gearbox, the diaphragm spring 10 is bowl-shaped, the diaphragm spring 10 is sleeved on the transmission shaft 1 and the outer ring is connected to the clutch pressure plate 9, the sliding sleeve 3 is connected to the clutch driving mechanism 5, the driver steps on the clutch pedal 51, the clutch pedal 51 drives the master cylinder 52 and drives the slave cylinder 54 to move through the oil pipe 53, pulls the fork 12, and the other end of the fork 12 pushes the sliding sleeve 3, so that the driving mechanism 5 drives the sliding sleeve 3 along the shaft sleeve 2 to the diaphragm The diaphragm spring 10 moves in the direction of the leaf spring 10, the center of the diaphragm spring 10 moves toward the direction close to the flying disc 6, and at the same time, the edge of the diaphragm spring 10 moves in the direction away from the flying disc 6, so as to drive the clutch pressure plate 9 and the friction plate 8 to separate from the flying disc 6 and disconnect the power of the engine. When the friction plate 8 of the clutch is worn and thinned, in order to ensure the clamping force of the friction plate 8, the outer ring of the diaphragm spring 10 will be pressed toward the direction of the flying disc 6, and at the same time, the center of the diaphragm spring 10 moves in the direction away from the flying disc 6, forcing the initial position of the sliding sleeve 3 to move away from the flying disc 6, causing the initial position to retreat, and the resistance mechanism The resistance mechanism 4 is arranged on one of the sleeve 3 or the shaft sleeve 2, and a pit 21 is arranged on the other of the two. The pit 21 arranged on the shaft sleeve 2 or the resistance mechanism 4 is arranged at the warning position. When the sleeve 3 moves to the warning position, the resistance mechanism 4 is engaged with the pit 21. When the driver steps on the clutch pedal 51 again, the sleeve 3 pushes the diaphragm spring 10. The resistance mechanism 4 will add a resistance to the original basic operating force due to the obstruction of the pit 21, forming a discomfort that can be clearly perceived by the driver, reminding the driver to replace the clutch as soon as possible to achieve the warning effect.

[0022] As an optional implementation, Figure 1 As shown, the resistance mechanism 4 is arranged on the sleeve 3, and the resistance mechanism 4 can extend out of the sleeve 3 and contact the shaft sleeve 2, the pit 21 is arranged on the shaft sleeve 2, the sleeve 3 drives the resistance mechanism 4 to move, the pit 21 is arranged on the shaft sleeve 2, and when the resistance mechanism 4 moves to the pit 21, it engages with the pit 21. In other embodiments, the resistance mechanism 4 can also be arranged on the shaft sleeve 2, and the pit 21 is arranged on the sleeve 3. In this case, the length of the sleeve 3 needs to cover the resistance mechanism 4 to prevent the sleeve 3 from contacting the resistance mechanism 4 during the movement and causing obstruction to the sleeve 3.

[0023] As an optional implementation, Figure 3 As shown, a mounting groove 31 for mounting the resistance mechanism 4 is provided on the sleeve 3, the mounting groove 31 extends radially along the sleeve 3 and a first opening 311 is provided at one end close to the sleeve 2, and the mounting groove 31 extends radially along the sleeve 3, that is, the mounting groove 31 is arranged perpendicular to the sleeve 2, so that the resistance mechanism 4 can enter the pit 21 to cause resistance to the sleeve 3.

[0024] Optionally, the resistance mechanism 4 includes a shell 41, an elastic member 42, a ball 44 and a mounting seat 43. For example, the elastic member 42 is a spring, the shell 41 is installed in the mounting groove 31 and the end of the shell 41 close to the shaft sleeve 2 is provided with a second opening 411 flush with the first opening 311, one end of the elastic member 42 abuts against the bottom of the shell 41, and the other end abuts against the mounting seat 43, the ball 44 is slidably connected to the side of the mounting seat 43 away from the elastic member 42, the end of the mounting seat 43 that contacts the elastic member 42 is provided with a groove so that the elastic member 42 can be stuck in the groove, and the end that contacts the ball 44 is provided with an arc groove that fits the ball 44. The mounting seat 43 is provided because the ball 44 will rotate. If the ball 44 directly contacts the elastic member 42, The elastic member 42 is bent and deformed, and the diameter of the second opening 411 is smaller than the maximum diameter of the ball 44 so that the ball 44 partially extends out of the shell 41 to prevent the ball 44 from detaching from the shell 41. The elastic member 42, the mounting seat 43 and the ball 44 are all arranged in the shell 41 to form a separate whole, which is convenient for installation and replacement. Under normal circumstances, the elastic member 42 is compressed and the ball 44 is located inside the sleeve 3. When the friction disk 8 wears and causes the initial position of the sleeve 3 to retreat, the resistance mechanism 4 moves to the pit 21. The ball 44 pops out into the pit 21 under the action of the elastic member 42, causing the sleeve 3 to be stuck. When the sleeve 3 moves again, the ball 44 compresses the elastic member 42 and retracts it into the sleeve 3, increasing the resistance to the sleeve 3 during the retraction process.

[0025] As an optional embodiment, the pit 21 is constructed as an annular groove arranged along the circumference of the sleeve 2, and multiple resistance mechanisms 4 can be arranged at intervals along the circumference of the sleeve 3. The pit 21 is an annular groove, and no matter how the sleeve 3 rotates, it can be ensured that the resistance mechanism 4 falls into the pit 21.

[0026] As an optional implementation, Figure 4-5 As shown, the clutch includes a flying disc 6 and a friction disc 8. The friction disc 8 is arranged on the side of the clutch pressure plate 9 close to the flying disc 6. When the friction disc 8 is in contact with the flying disc 6, the resistance mechanism 4 is located at the initial position. The early warning position is arranged on the path where the resistance mechanism 4 moves from the initial position to the direction away from the clutch pressure plate 9 after the friction disc 8 is worn, that is, the early warning position is arranged on the side of the initial position away from the clutch pressure plate 9. After the initial position of the sleeve 3 is retracted, the resistance mechanism 4 is engaged with the pit 21.

[0027] Optionally, the early warning position is set at the position where the resistance mechanism 4 is located when the friction disc 8 is worn to 85%-100%, and the length of the pit 21 extending along the axial direction of the sleeve 2 is the distance that the resistance mechanism 4 moves when the wear of the friction disc 8 is worn from 85% to 100%, that is, when the friction disc 8 is worn to 85%-100%, the resistance mechanism 4 falls into the pit 21. In fact, the early warning starts when the friction disc 8 is worn to 85%. However, if the pit 21 is only set at the 85% position, the pit 21 will hinder the sleeve 3 from retreating, so that the clamping force of the diaphragm spring 10 is insufficient after the friction disc 8 continues to wear, causing the clutch to slip.

[0028] As an optional implementation, Figure 3 As shown, the height of the pit 21 is less than 1 / 2 of the height of the ball 44, and the two sides of the pit 21 are constructed as slopes, so that the ball 44 can be more easily separated from the pit 21, because the role of the pit 21 is only to generate resistance to the sliding sleeve 3, so that the driver feels a sense of frustration when stepping on the clutch, and it is not intended to jam the sliding sleeve 3.

[0029] like Figure 1-2 As shown, the second purpose of the present disclosure is to provide a clutch, including: the above-mentioned clutch life warning device. When the driver steps on the clutch pedal 51 again to make the sleeve 3 push the diaphragm spring 10, the resistance mechanism 4 will add a resistance to the original basic operating force due to the obstruction of the pit 21, forming a sense of discomfort that can be clearly felt by the driver, reminding the driver to replace the clutch as soon as possible. The structure is simple and the cost is low.

[0030] The third object of the present disclosure is to provide a vehicle, comprising: the above-mentioned clutch, which performs an early warning through a clutch life early warning device to improve the safety of the vehicle.

[0031] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0033] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
