Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a novel automotive disc spring. Background Technology

[0002] Automotive disc springs are a special type of spring design, primarily used in various automotive components to provide necessary elasticity and support. They are typically made of metallic materials, such as spring steel, which possess high strength and durability.

[0003] However, existing automotive disc springs still have the following defects: Since the current disc springs are connected to the car clutch by connecting the outer ring and the fixing adjustment bolts, the fixing adjustment bolts can be connected to the clutch in a ring-shaped distribution. Therefore, after the fixing adjustment bolts on the edge are locked in one by one, the center point of the conical disc is easily deviated from the center point of the clutch due to the different locking force. This deviation in the center will cause uneven force when axial force is applied. In turn, the persistent uneven force will easily cause excessive deformation of the surface of the conical disc, which will eventually destroy the symmetrical shape of the conical disc and damage the disc spring, thus reducing the practical strength of the disc spring. Utility Model Content

[0004] To address the above problems, this utility model provides a novel automotive disc spring.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel automotive disc spring, the structure of which includes: a connecting chassis, a conical spring disc, a fixing adjusting bolt, a radial groove, and a guide positioning structure. The connecting chassis and the center of the conical spring disc coincide with each other, and the surface edge carries the fixing adjusting bolt. The radial groove is opened on the surface of the conical spring disc and is spaced to fit the fixing adjusting bolt. The guide positioning structure is vertically installed at the center of the conical spring disc and coincides with its center.

[0006] Furthermore, the guiding and positioning structure is also provided with an adsorption disk, the contact layer edge of the adsorption disk surface is connected to a restraining column, a vertical central cylinder is connected to the central area of ​​the adsorption disk, and a through slot is opened in the center of the vertical central cylinder.

[0007] Furthermore, the guide positioning structure at the center of the conical spring disc utilizes the contact layer of the adsorption plate and the edge restraining post to restrain and fix the connecting chassis to the center of the conical spring disc. In turn, the vertical center cylinder at the center of the adsorption plate, combined with the through slot, forcibly restrains the guide post of the car clutch in the center point area.

[0008] Furthermore, the connecting chassis covers the edge of the conical spring disc, and six fixing and adjusting bolts are arranged in a ring shape on the surface edge of the conical spring disc. The guide positioning structure intersects with the center of the conical spring disc.

[0009] Furthermore, the contact layer of the adsorption plate is provided with four solid vertical restraining columns, and the through slot of the vertical center cylinder is circular in shape and opened in a vertical orientation.

[0010] Furthermore, the inner wall edge of the vertical center cylinder is also provided with a connecting inner ring. The connecting inner ring positions the detection module and the front end of the detection module is provided with an electric groove. The outside of the connecting inner ring is connected to the loading groove, and a small position sensor is fixed in the loading groove by a positioning ring. The lower end of the small position sensor is connected to the detection module and electrically connected to the electric groove. A solid outer ring wall is also provided outside the loading groove.

[0011] Furthermore, the inner ring of the connection is equipped with three sets of detection modules set in a triangular orientation, and the power-conducting groove of the detection module is an arc-shaped concave shape to allow the power-conducting area of ​​the guide column of the car clutch to be embedded. The positioning ring of the loading groove determines the position of the three sets of small position sensors.

[0012] Furthermore, an overlapping layer is provided in the area where the fixed adjusting bolt connects to the edge of the conical spring disc. The overlapping layer is located in the lower part of the disc, and a limiting ring is connected to the center of the disc to restrain the edge of the anti-deviation column. The anti-deviation column passes vertically through the center of the disc through the limiting ring. A threaded groove is also opened inside the center of the anti-deviation column to match the external thread of the fixed adjusting bolt.

[0013] Furthermore, the overlapping layer at the lower end of the disk is flattened and overlaps with the surface layer of the conical spring disc. The diameter of the limiting ring is larger than the diameter of the anti-deviation column, which restrains its edge. The threaded groove inside the anti-deviation column is opened in a vertical direction and forms a cross shape with the disk. Beneficial effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model further improves the guiding and positioning structure of the conical spring disc's central area. The contact layer of the adsorption plate contacts the bottom of the car, and the surface restraint column improves the overlap accuracy between the chassis and the conical spring disc. Furthermore, the slot of the vertical center cylinder allows the guide column of the car clutch to be vertically inserted, confining it to the center point. This avoids the center point offset caused by locking the edge fixing bolts one by one, ensuring uniform force on the surface of the conical spring disc and preventing deformation caused by uneven force. Therefore, it improves the practicality and stability of the car disc spring.

[0016] 2. This utility model further improves upon the inner wall of the vertical center column by connecting three sets of detection modules mounted on the inner ring. These modules can be electrically connected to the energized protrusions of the car guide column via an energized groove. This allows the detection modules and the small position sensor in the loading groove to be electrically connected to the car. Therefore, by utilizing the position restraint of the three sets of detection modules and the function of the small position sensor, the vertical position of the clutch guide column can be effectively identified, ensuring a stable vertical orientation and avoiding inaccurate positioning caused by tilting deviation. This further improves the connection accuracy between the car disc spring and the car clutch center.

[0017] 3. This utility model further improves the contact position between the fixing adjusting bolt and the conical spring disc by aligning the overlapping layer of the disc with the edge of the conical spring disc surface, and then uses a limiting ring to vertically position the anti-deviation column, so that the internal thread groove of the anti-deviation column allows the fixing adjusting bolt to be locked in a straight line, avoiding tilting during locking, and improving the vertical stability of the adjusting spring preload.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0028] like Figures 1-4 As shown, this utility model provides a novel automotive disc spring.

[0029] Its structure includes a connecting base 1, a conical spring disc 2, a fixing and adjusting bolt 3, a radial groove 4, and a guide and positioning structure 5. The connecting base 1 and the conical spring disc 2 have their centers coincident and the surface edge carries the fixing and adjusting bolt 3. The radial groove 4 is opened on the surface of the conical spring disc 2 and is spaced to fit the fixing and adjusting bolt 3. The guide and positioning structure 5 is vertically installed at the center of the conical spring disc 2 and coincides with its center.

[0030] The guide positioning structure 5 is also provided with an adsorption disk 51. The edge of the contact layer 52 on the surface of the adsorption disk 51 is connected to a restraining column 53. A vertical center cylinder 54 is connected to the center area of ​​the adsorption disk 51, and a through slot 55 is opened in the center of the vertical center cylinder 54.

[0031] Among them, the guide positioning structure 5 at the center of the conical spring disc 2 uses the contact layer 52 of the adsorption plate 51 and the edge restraining column 53 to restrain and fix the connecting chassis 1 and the center of the conical spring disc 2. Then, the vertical center cylinder 54 at the center of the adsorption plate 51, combined with the through slot 55, forcibly restrains the guide column of the car clutch in the center point area.

[0032] The connecting chassis 1 covers the edge of the conical spring disc 2, and six fixing and adjusting bolts 3 are arranged in a ring shape on the surface edge of the conical spring disc 2. The guide positioning structure 5 intersects with the center of the conical spring disc 2.

[0033] The adsorption disk 51 has four solid vertical restraining columns 53 on the contact layer 52, and the slot 55 of the vertical center cylinder 54 is circular and opened in a vertical direction.

[0034] The inner wall edge of the vertical center cylinder 54 is also provided with a connecting inner ring 541. The connecting inner ring 541 positions the detection module 542 and the front end of the detection module 542 is provided with an electric groove 543. The outer side of the connecting inner ring 541 communicates with the loading groove 544 and a small position sensor 546 is fixed in the loading groove 544 by a positioning ring 545. The lower end of the small position sensor 546 is connected to the detection module 542 and electrically connected to the electric groove 543. A solid outer ring wall 547 is also provided outside the loading groove 544.

[0035] The inner ring 541 is equipped with three sets of detection modules 542 set in a triangular orientation, and the energized groove 543 of the detection module 542 is an arc-shaped concave shape to allow the energized area of ​​the guide column of the car clutch to be embedded. The positioning ring 545 of the loading groove 544 determines the position of the three sets of small position sensors 546.

[0036] The fixed adjusting bolt 3 and the edge of the conical spring disc 2 are connected by an overlapping layer 31. The overlapping layer 31 is located on the lower part of the disc 32, and the center of the disc 32 is connected to a limiting ring 33 to restrain the edge of the anti-deviation column 34. The anti-deviation column 34 passes vertically through the center of the disc 32 through the limiting ring 33. The center of the anti-deviation column 34 is also provided with a threaded groove 35 that is compatible with the external thread of the fixed adjusting bolt 3.

[0037] The overlapping layer 31 at the lower end of the disc 32 is flattened and overlaps with the surface of the conical spring disc 2. The diameter of the limiting ring 33 is larger than the diameter of the anti-deviation column 34, which restrains its edge. The threaded groove 35 inside the anti-deviation column 34 is opened in a vertical direction and forms a cross shape with the disc 32.

[0038] The working principle of this utility model is explained below: The automotive disc spring can be mounted on the chassis 1 to install the conical spring disc 2 in the rebound area of ​​the automotive clutch. Then, the fixing and adjusting bolts 3 on the edge of the conical spring disc 2 can be locked according to the preload required by the automotive clutch, allowing the conical spring disc 2 to be used with the clutch with a suitable rebound force. Furthermore, the radial grooves 4 on the surface of the conical spring disc 2 allow the automotive clutch components to be embedded. Simultaneously, the guide positioning structure 5 limits the clutch guide rod, ensuring that the surface of the conical spring disc 2 can form a uniform force distribution, preventing deformation caused by continuous uneven force distribution. Therefore, through the cooperation of the guide positioning structure 5, it utilizes the surface of the suction cup 51 to... The contact layer 52 and four restraining pillars 53 improve the connection and fixation between the conical spring disc 2 and the connecting chassis 1. Simultaneously, the vertical center cylinder 54 in the central area can restrain the car clutch guide rod through the through slot 55, preventing center point deviation caused by errors in locking force after the fixing adjusting bolts 3 are individually locked in. This prevents uneven force distribution caused by the error between the center point of the car clutch and the center point of the conical spring disc 2. Furthermore, the through slot 55 of the vertical center cylinder 54 is equipped with a connecting inner ring 51 to position the detection module 542. After the car clutch guide rod and energized components are vertically embedded, the energized slot 543 of the detection module 542 allows the car clutch components to be embedded, enabling detection... Module 542 is powered on by the vehicle through the power supply slot 543. Simultaneously, the detection module 542 transmits electrical energy to the positioning ring 545 of the loading slot 544 after being powered on, activating the small position sensor 546. Therefore, the position monitoring using three sets of detection modules 542 and small position sensors 546 improves the alignment strength between the vehicle's clutch center point and the center point of the conical spring disc 2, enhancing the stability of their coincidence. The small position sensor 546 is then stably installed in the positioning ring 545 of the loading slot 544 under the cover of the solid outer ring 547. If any set of small position sensors 546 fails to properly power on the vehicle, it will indicate a misalignment between the center point of the conical spring disc 2 and the vehicle's clutch center point. The overlapping structure significantly improves the precision of the connection between the disc spring and the vehicle. Furthermore, the area where the adjusting bolt 3 connects to the edge of the conical spring disc 2 is equipped with a disc 32. The overlapping layer 31 of the disc 32 allows the limiting ring 33 to be installed parallel to the edge of the conical spring disc 2. The limiting ring 32 then vertically fixes the anti-deviation post 34, ensuring it intersects with the disc 32. Finally, the anti-deviation post 34 uses a threaded groove 35 to vertically lock the adjusting bolt 3 in, effectively improving the verticality of the adjusting bolt 3 and preventing tilting errors during preload adjustment. This ensures the entire component can be set with precise vertical orientation.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
