Abstract
Description
Technical Field:
[0001] The utility model relates to the technical field of clutches, and more specifically to a part for transmitting the kinetic energy of an engine. Background Art:
[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. During the driving of an automobile, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the gearbox, so as to cut off or transmit the power input from the engine to the transmission. At present, the main component for realizing the clutch function is the clutch disc. At present, the clutch disc of the sliding clutch is composed of an outer clutch steel sheet and an inner friction sheet. Among them, a number of annularly and evenly distributed supporting pieces are formed on the outer ring of the clutch steel sheet. Based on the cooperation of the supporting pieces with the clamping grooves on the clutch pressure housing, the rotation of the clutch steel sheet is restricted. The existing supporting pieces and the clutch steel sheet are in the same plane, and the number of the supporting pieces is at least 6, which requires at least six clamping grooves to be opened on the clutch pressure housing. The more the clamping grooves are, the weaker the strength of the clutch pressure housing. Therefore, someone proposed to reduce the number of the supporting pieces to two symmetrical ones, so that the clutch pressure housing only needs to be provided with two clamping grooves. However, during the use process, the stress is concentrated on only two supporting pieces, and the situation of the supporting pieces breaking is likely to occur. Therefore, it is necessary to optimize and improve this structure. Content of the Utility Model:
[0003] The purpose of the utility model is to aim at the deficiencies of the existing technology, and provides a part for transmitting the kinetic energy of an engine, which improves the anti-shear strength of the supporting lugs by bending the supporting lugs on the clutch steel sheet and adding rib grooves, so that the clutch steel sheet still has good strength when only two supporting lugs are provided.
[0004] A part for transmitting the kinetic energy of an engine includes an annular steel sheet. On the opposite outer walls of the left and right sides of the steel sheet, there are formed limiting supporting lugs that are bent upward and are in an L shape. In the middle of the limiting supporting lugs, there are formed reinforcing rib grooves that are recessed inward.
[0005] On the steel sheet to the left of the central hole of the steel sheet, there is formed a downward protruding and cylindrical lower positioning bump, and on the steel sheet to the right of the central hole of the steel sheet, there is formed an upward protruding and cylindrical upper positioning bump.
[0006] Preferably, annular limiting bumps are respectively formed on the outer walls of the steel sheet near the two limiting supporting lugs.
[0007] Preferably, the diameter of the lower positioning bump is equal to the diameter of the upper positioning bump, and the center distance from the lower positioning bump to the center of the steel sheet is equal to the center distance from the upper positioning bump to the center of the steel sheet.
[0008] Preferably, laser stripe-shaped grooves are respectively formed on the upper end surface and the lower end surface of the steel sheet.
[0009] Preferably, the limiting lug is composed of an obliquely arranged connecting part and a horizontal limiting part, and the reinforcing rib groove is located in the middle of the connecting part.
[0010] Preferably, the outer side edge of the limiting lug on the steel sheet is arc-shaped, and the center of the arc of the outer side edge of the limiting lug is located on the central axis of the steel sheet;
[0011] The arc radian of the outer side edge of the limiting lug is equal to π / 6 to π / 4.
[0012] The beneficial effects of the present utility model are as follows:
[0013] By bending the lugs on the clutch steel sheet and adding rib grooves, the shear strength of the lugs is improved, so that the clutch steel sheet still has good strength even when only two lugs are provided. Brief description of the drawings:

[0018] Embodiment: As shown in Figures 1 to 3 shown, an engine kinetic energy transmission part includes an annular steel sheet 1. On the opposite outer walls of the left and right sides of the steel sheet 1, there are formed limiting lugs 11 that are bent upward and are in an L shape. The limiting lugs 11 are mainly formed by stamping. In the middle of the limiting lugs 11, there is formed a reinforcing rib groove 12 that is recessed;
[0019] On the steel sheet 1 on the left side of the central hole of the steel sheet 1, there is formed a downward protruding and cylindrical lower positioning bump 13, and on the steel sheet 1 on the right side of the central hole of the steel sheet 1, there is formed an upward protruding and cylindrical upper positioning bump 14.
[0020] As shown in Figure 3 shown, on the outer walls of the steel sheet 1 near the two limiting lugs 11, there are respectively formed annular limiting convex blocks 15. Between the two ends of the limiting convex blocks 15 and the outer wall of the steel sheet 1, there are formed arc-shaped relief grooves; the limiting convex blocks 15 can further limit the radial rotation of the steel sheet 1.
[0021] The diameter of the lower positioning bump 13 is equal to that of the upper positioning bump 14, and the center distance from the lower positioning bump 13 to the center of the steel sheet 1 is equal to the center distance from the upper positioning bump 14 to the center of the steel sheet 1. The lower positioning bump 13 and the upper positioning bump 14 are respectively the positioning base points of the friction sheets on the upper and lower sides of the steel sheet 1.
[0022] Laser stripe-like grooves 16 are respectively formed on the upper end surface and the lower end surface of the steel sheet 1, and the grooves 16 can increase the friction force on the upper and lower end surfaces of the steel sheet 1.
[0023] The limiting lug 11 is composed of an obliquely arranged connecting part and a horizontal limiting part, and the reinforcing rib groove 12 is located in the middle of the connecting part.
[0024] The outer side edge of the limiting lug 11 on the steel sheet 1 is arc-shaped, and the center of the arc of the outer side edge of the limiting lug 11 is located on the central axis of the steel sheet 1; the limiting lug 11 is a support plate with an arc-shaped outer side and straight front and rear side edges before stamping. When stamping, the reinforcing rib groove 12 is formed, so that Figure 3 As shown, its connecting part is compressed and narrowed, and the limiting part becomes a fan-shaped ring.
[0025] The arc radian of the outer side edge of the limiting lug 11 is equal to π / 6 - π / 4. Since the limiting lug 11 is mainly used to limit the radial rotation of the steel sheet 1, a certain width is required to ensure strength.
[0026] Working principle: This structure is a part for transmitting the kinetic energy of the engine. The technical point is that only two limiting lugs 11 are provided on both sides of the steel sheet 1. The limiting lugs 11 are L-shaped. Compared with the existing support pieces on the steel sheet 1, its width is increased, and at the same time, a reinforcing rib groove 12 is added to ensure the strength of the limiting lugs 11 and prevent the connection between the limiting lugs 11 and the steel sheet 1 from breaking;
[0027] At the same time, a lower positioning bump 13 and an upper positioning bump 14 are added to facilitate the positioning of the friction sheets on both sides of the steel sheet 1.
[0028] The described embodiments are used to illustrate the present invention by way of example, rather than to limit the present invention. Any person skilled in the art can modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of the rights protection of the present invention should be as listed in the claims of the present invention.
