[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] refer to Figures 1 to 6 As shown, a vibration-resistant torque converter provided according to one aspect of the present invention is composed of at least a housing 1, a pump wheel, a guide wheel 6, a turbine, a connecting plate 7, a driven plate 8, an anti-vibration ball 9, a chassis 10 and an output roller 11.

[0024] The pump wheel includes a pump wheel blade 2 and a pump wheel housing 3, the turbine includes a turbine housing 4 and a turbine blade 5, the pump wheel housing 3 is connected and fixed to the housing 1, the turbine is arranged on the side of the housing 1 opposite to the pump wheel and is not fixed on the housing 1, the guide wheel 6 is arranged in the middle position between the pump wheel and the turbine, the center position of the turbine housing 4 is connected to the connecting disk 7, the connecting disk 7 is connected to the output roller 11, the inner side of the ring of the pump wheel is connected to the driven disk 8, the outer ring of the driven disk 8 is set to an arc-shaped groove, and the outer ring of the driven disk 8 is connected to the outer ring of the pump wheel. The chassis 10 is arranged inside the outer casing 1 and is located on the same side as the turbine. The chassis 10 is adjacent to the driven disk 8 and the back side of the outer casing 1. The chassis 10 is in contact with the outer casing 1 on the radial surface but not on the circumferential surface. The chassis 10 and the arc-shaped groove of the driven disk 8 clamp the anti-seismic ball 9. When the chassis 10 is stationary on the flat ground, the maximum axial distance from the inner side of the arc-shaped groove to the chassis 10 is consistent with the diameter of the anti-seismic ball 9.

[0025] In some embodiments, a gasket 12 is provided between the chassis 10 and the connecting plate 7 , and a raised ring is provided in the axial direction of the gasket 12 , and the raised ring is located on one side of the chassis 10 .

[0026] In some embodiments, the turbine casing 4 is structurally divided into an arc surface ring portion 13, a bevel ring portion 14 and a plane ring portion 15. The bevel ring portion 14 is respectively connected to the arc surface ring portion 13 and the plane ring portion 15. In the axial direction, the bevel ring portion 14 is inclined toward the back side of the casing 1. The plane ring portion 15 is connected to the connecting disk 7 and the driven disk 8. The arc surface ring portion 13 is connected to the impeller blades 2.

[0027] In some embodiments, the chassis 10 is structurally divided into an outer ring 16, a middle ring 17 and an inner ring 18. The middle ring 17 connects the outer ring 16 and the inner ring 18 respectively. In the axial direction, the inner ring 18 protrudes toward the front side of the outer shell 1 compared to the middle ring 17, and the middle ring 17 protrudes toward the front side of the outer shell 1 compared to the outer ring 16. The outer ring 16 corresponds to the arc-shaped groove.

[0028] In some embodiments, a friction ring is disposed on the inner side of the back side of the housing 1 , the friction ring is in contact with the outer ring 16 , and the friction ring is coaxial with the chassis 10 .

[0029] During the operation of the torque converter, the turbine is driven to rotate. When passing through a road area with poor road conditions, the entire vehicle vibrates, and the tires will also move up and down due to the up and down bumps, resulting in the vehicle as a whole having an up and down bump condition or tendency. Therefore, corresponding to the torque converter, the output roller 11 is offset up and down due to the up and down bumps, resulting in the up and down offset of the turbine housing 4, which further causes the driven plate 8 connected to the turbine housing 4 to deviate up and down, resulting in the arc wall on the inner side of the arc-shaped groove on the outer side of the driven plate 8 contacting the anti-shock ball 9. The anti-shock ball 9 is made of elastic material, so the anti-shock ball 9 is deformed under the extrusion of the arc-shaped groove on the inner side of the driven plate 8, thereby absorbing the up and down vibrations caused by the bumps to a certain extent, and converting the force generated by the up and down bumps into the elastic force of the anti-shock ball 9, thereby obtaining elastic potential energy, and the elastic potential energy helps to push the driven plate 8 back to its original state.

[0030] Since there are anti-vibration balls 9 on both the upper and lower sides of the cross section, when bumping upward, the upper anti-vibration balls 9 will work, so that there is a downward elastic force after absorbing a certain amount of vibration, and the lower anti-vibration balls 9 will work when bumping downward, so that there is an upward elastic force after absorbing a certain amount of vibration, thereby greatly reducing the impact of vibration, and at the same time will not increase the fixed structure inside the torque converter too much, which will cause too many fixed structures in the torque converter, so that when displacement or displacement tendency occurs, only rigid force will act, resulting in greater damage. The same is true for the front and rear displacement.

[0031] Furthermore, during the up and down vibration and the front and back vibration, the elastic force generated by the upper vibration causes the components inside the torque converter to have an overall downward movement trend and consume a certain amount of energy brought by the upward displacement, thereby causing a downward displacement. The downward displacement has a certain amount of downward vibration, so that the anti-vibration ball 9 below is deformed, resulting in an upward movement trend and consuming a certain amount of energy brought by the downward displacement, thereby forming a consumption of the vibration inside the torque converter, thereby forming an anti-vibration effect.

[0032] Furthermore, a gasket 12 is provided between the chassis 10 and the connecting plate 7, and a raised ring is provided in the axial direction of the gasket 12, and the raised ring is located on one side of the chassis 10. A friction ring is provided on the inner side of the back side of the outer shell 1, and the friction ring is in contact with the outer ring 16. The friction ring is coaxial with the chassis 10, so that it is ensured that no direct friction is generated between the driven plate 8 and the chassis 10, and no loss of equipment is generated due to friction between the chassis 10 and the outer shell 1.

[0033] Furthermore, since the anti-vibration ball 9 is arranged between the driven plate 8 and the chassis 10, during the rotation of the driven plate 8 and the rotation of the chassis 10, a large amount of sliding friction that may exist is changed into rolling friction through the anti-vibration ball 9, making the rotation inside the torque converter smoother.

[0034] refer to Figure 1-6 As shown. In some embodiments, the anti-vibration ball 9 includes a ball shell and a plurality of first spring groups 19, a plurality of second spring groups 20, and a plurality of third spring groups 21. The first spring group 19, the second spring group 20, and the third spring group 21 are all arranged in multiple layers. The springs of each layer in the first spring group 19 are parallel to each other, and the layers are parallel to each other. The springs of each layer in the second spring group 20 are parallel to each other, and the layers are parallel to each other. The springs of each layer in the third spring group 21 are parallel to each other, and the springs in the first spring group 19 are perpendicular to the springs in the second spring group 20 and the springs in the third spring group 21. The springs in the second spring group 20 are perpendicular to the springs in the third spring group 21.

[0035] In some embodiments, the outer ring 16 is provided with an axial convex ring 22, and a first limiting ring 23 and a second limiting ring 24 are provided on the inner side of the axial convex ring 22, the first limiting ring 23 and the second limiting ring 24 clamp a shockproof ring 25, the inner edge of the shockproof ring 25 is arc-shaped, and the inner edge of the shockproof ring 25 contacts the driven disk 8, and an elastic ring is provided between the outer side of the shockproof ring 25 and the axial convex ring 22.

[0036] In some embodiments, a plurality of first sliding grooves are arranged on the front side of the first limiting ring 23, and a plurality of second sliding grooves are arranged on the rear side of the second limiting ring 24. The first sliding grooves and the second sliding grooves are both arranged radially. A first limiting block is arranged on the front side of the shockproof ring 25, and a second limiting block is arranged on the rear side. The first limiting block is placed in the first sliding groove, and the second limiting block is placed in the second sliding groove.

[0037] Since the springs of each layer in the first spring group 19 of the earthquake-resistant ball 9 are parallel to each other and the layers are parallel to each other, the springs of each layer in the second spring group 20 are parallel to each other and the layers are parallel to each other, and the springs of each layer in the third spring group 21 are parallel to each other and the layers are parallel to each other, the springs in the first spring group 19 and the springs in the second spring group 20 and the springs in the third spring group 21 are perpendicular to each other, and the springs in the second spring group 20 and the springs in the third spring group 21 are perpendicular to each other, that is, there is elastic force that can be strained and squeezed in the transverse, longitudinal and vertical directions, and since there are many layers in the first spring group 19, the second spring group 20 and the third spring group 21, there is a relatively full spring network in the entire earthquake-resistant ball 9, so that the earthquake-resistant ball 9 can cope with the deformation caused by squeezing in all directions.

[0038] As for the axial convex ring 22 and the shockproof ring 25, during the vibration process, the driven disk 8 is displaced, so that the arc-shaped groove of the driven disk 8 will squeeze the shockproof ring 25, so that the shockproof ring 25 will have a displacement and displacement trend toward the axial convex ring 22, and the shockproof ring 25 will squeeze the spring, and under the action of the spring, the spring will convert the squeezing force transmitted by the shockproof ring 25 into elastic force, thereby reducing the vibration amount. As for the shockproof ring 25, since a plurality of first sliding grooves are arranged on the front side of the first limiting ring 23 and a plurality of second sliding grooves are arranged on the rear side of the second limiting ring 24, the first sliding groove and the second sliding groove are both arranged along the radial direction, the first limiting block is arranged on the front side of the shockproof ring 25 and the second limiting block is arranged on the rear side, the first limiting block is placed in the first sliding groove, and the second limiting block is placed in the second sliding groove, so that the shockproof ring 25 can slide through the first limiting block and the second limiting block, and at the same time, the first sliding groove and the second sliding groove can also produce position constraints on the first limiting block and the second limiting block.
