Description

Technical Field

[0001] The utility model relates to the technical field of automotive power transmission, and particularly to an angle adjustment device for a high-efficiency dual-mass flywheel. Background Technique

[0002] With the development of the automotive industry, improving driving comfort and the reliability of the transmission system has become one of the important goals pursued by automotive manufacturers. As an effective vibration damping device, the dual-mass flywheel is widely used between the automotive engine and the transmission to reduce the vibration caused by the change of the engine speed and improve driving comfort. However, in some extreme working conditions of traditional dual-mass flywheels, such as when the vehicle accelerates or decelerates suddenly, the relative rotation angle between the two flywheels inside the flywheel may exceed the predetermined safety range, resulting in the transmission system being subjected to excessive impact, thereby affecting the life and performance of the transmission system. For this reason, we propose an angle adjustment device for a high-efficiency dual-mass flywheel. Content of the Utility Model

[0003] The purpose of the utility model is to provide an angle adjustment device for a high-efficiency dual-mass flywheel, which adjusts the relative rotation angle between the two flywheels by changing the pre-tightening force of the arc spring, with a simple and efficient structure, and solves the problems in the prior art.

[0004] To achieve the above purpose, the utility model provides the following technical solution:

[0005] An angle adjustment device for a high-efficiency dual-mass flywheel includes a first mass and a second mass. The first mass and the second mass are connected into a whole through a spring damper. A bearing is provided in the middle of the first mass, and a connecting plate is sleeved on the outer ring of the bearing. Spring seats are symmetrically arranged on the outer edge of the connecting plate. A guiding groove is arranged at the inner edge of the first mass, and an arc spring is arranged in the guiding groove. The arc springs are symmetrically distributed on both sides of the connecting plate, and the outer ends of the arc springs abut against the spring seats. Each arc spring is divided into two sections, and the two sections are connected by a plurality of adjusting members arranged in a row.

[0006] Preferably, the adjusting member includes a connecting plate and a connecting column, and connecting plates are fixed at both ends of the connecting column.

[0007] Preferably, the cross-section of the connecting plate is an isosceles trapezoid, and the narrower side faces the center point of the first mass.

[0008] Preferably, mounting holes are provided on the connecting plate, and not less than three mounting holes are provided on each connecting plate.

[0009] Preferably, the mounting holes on adjacent connecting plates are in corresponding positions, and adjacent connecting plates are connected by fixing bolts passing through the mounting holes.

[0011] Preferably, the diameter of the connecting plate does not exceed the outer diameter of the arc-shaped spring.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, each arc-shaped spring is divided into two sections, and the two sections are connected by a number of adjusting members arranged in a row. The adjusting members are connected in series according to the actual adjustment situation. When it is necessary to reduce the relative rotation angle, the number of adjusting members is increased to squeeze the arc-shaped springs at both ends, thereby adjusting the pre-tightening force of the arc-shaped springs. The greater the pre-tightening force, the smaller the relative rotation angle between the first mass and the second mass, and vice versa. The structure is simple and efficient.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] In order to solve the problem in the prior art that the rotation angle of the dual-mass flywheel cannot be simply and effectively adjusted, the following technical solutions are given. Please refer to Figures 1-5 ;

[0022] An angle adjustment device for a high-performance dual-mass flywheel, comprising a first mass 1 and a second mass 2. The first mass 1 and the second mass 2 are connected as a whole through a spring damper. A bearing 3 is provided in the middle of the first mass 1. A connecting plate 4 is sleeved on the outer ring of the bearing 3. Spring seats 5 are symmetrically provided on the outer edge of the connecting plate 4. A guiding groove 6 is provided at the inner edge of the first mass 1. An arc-shaped spring 7 is provided in the guiding groove 6. The arc-shaped springs 7 are symmetrically distributed on both sides of the connecting plate 4. The outer end of the arc-shaped spring 7 abuts against the spring seat 5. Each arc-shaped spring 7 is divided into two sections, and the two sections are connected by a number of adjusting members 8 arranged in a row. The adjusting members 8 can be connected in series according to the actual adjustment situation. By squeezing the arc-shaped springs 7 at both ends of the adjusting members 8, the pre-tightening force of the arc-shaped springs 7 can be adjusted. The greater the pre-tightening force, the smaller the relative rotation angle between the first mass 1 and the second mass 2, and vice versa.

[0023] The adjusting member 8 includes a connecting plate 9 and a connecting column 10. Connecting plates 9 are fixed at both ends of the connecting column 10. The cross-section of the connecting plate 9 is an isosceles trapezoid, and the narrower side faces the center point of the first mass 1. The diameter of the connecting plate 9 does not exceed the outer diameter of the arc-shaped spring 7. The inner end of the arc-shaped spring 7 is fixedly connected to the outermost connecting plate 9. When the connecting plates 9 are connected, the different thicknesses on the inner and outer sides cause the overall direction of the connecting plate 9 and the connecting column 10 to bend towards the center point of the first mass 1, forming the same arc as the arc-shaped spring 7, which is convenient for the connecting plate 9 and the connecting column 10 to slide in the guiding groove 6 along with the expansion and contraction of the arc-shaped spring 7; in actual applications, the thicknesses of the inner and outer sides of the connecting plate 9 need to be set according to the bending arc of the arc-shaped spring 7.

[0024] Mounting holes 11 are provided on the connecting plate 9. Each connecting plate 9 is provided with no less than three mounting holes 11; the positions of the mounting holes 11 on adjacent connecting plates 9 correspond to each other, and adjacent connecting plates 9 are connected by fixing bolts 12 passing through the mounting holes 11, which is convenient for connecting the connecting plates 9 and the connecting columns 10 in series.

[0025] Working principle: Each arc-shaped spring 7 is divided into two sections, and each section is connected by a number of connecting plates 9 and connecting columns 10. When it is necessary to reduce the relative rotation angle between the first mass 1 and the second mass 2, the number of adjusting members 8 is increased to squeeze the arc-shaped springs 7 at both ends to increase their pre-tightening force, and vice versa; during installation, the mounting holes 11 on adjacent connecting plates 9 are aligned, and the fixing bolts 12 are passed through the mounting holes 11 and tightened and fixed.

[0026] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0027] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
