The dual-mass flywheel is a part widely applied to modern automobiles, and has very remarkable functions of vibration reduction and noise reduction. The dual mass flywheel mainly comprises a primary flywheel and a secondary flywheel, and a flange plate which plays a role in force transmission is generally arranged between the primary flywheel and the secondary flywheel. One end face of the flange of the traditional dual-mass flywheel is directly contacted with the primary flywheel for working, and when the dual-mass flywheel works, relative motion exists between the flange and the primary flywheel, so that sliding friction and relatively large abrasion are easy to generate.
In order to reduce the larger abrasion when the flange plate and the primary flywheel relatively move, a rolling contact type force transmission structure inside the dual-mass flywheel is designed, the structure replaces the original sliding friction by rolling friction, the straight spring can reduce the axial impact between the flange plate and the primary flywheel, and meanwhile, the structure is simple, and the assembly and the disassembly are convenient.
Disclosure of Invention
In order to solve the problem of larger abrasion during relative sliding between the traditional flange plate of the dual-mass flywheel and the primary flywheel, the utility model structurally improves and designs an internal rolling contact type force transmission structure of the dual-mass flywheel, which comprises a flange plate body, a lower roller support, a straight spring, a spherical roller, an upper roller support and a fixing screw. The lower roller support is welded on the flange plate body, the straight springs are placed in cylindrical holes of the lower roller support, the spherical rollers are placed in roller grooves of the lower roller support, and the upper roller support and the lower roller support are fixed by fixing screws. The flange body both ends have the boss for compress the arc spring in the dual mass flywheel, the flange body center digs has a through-hole, evenly distributed has four screw holes around the through-hole, fixes flange body and secondary flywheel through the screw.
As a further improvement of the scheme, the flange plate body is uniformly welded with a roller lower support, and a hemispherical roller groove is dug on the roller lower support.
As a further improvement of the scheme, four threaded holes are uniformly distributed around the roller groove, and a cylindrical hole is dug in the middle of the hemispherical roller groove.
As a further improvement of the above scheme, the straight spring is placed in the cylindrical hole in the center of the roller groove, and the straight spring is higher than the upper surface of the cylindrical hole in the center of the roller groove to provide corresponding elastic force.
As a further improvement of the above, the ball roller is placed in a hemispherical roller groove, and the straight spring is in a compressed state.
As a further improvement of the scheme, the upper roller support with the hemispherical roller groove dug in the middle is assembled with the lower roller support through the fixing screw, and part of the spherical roller is exposed from the upper roller support, so that the roller can roll normally.
Compared with the prior dual-mass flywheel flange, the internal rolling contact type force transmission structure of the dual-mass flywheel replaces sliding friction with rolling friction of the dual-mass flywheel flange and the primary flywheel, so that abrasion during relative movement of the flange and the primary flywheel is reduced, the service life is prolonged, axial impact of the flange and the primary flywheel can be reduced by the straight spring in the structure, and the whole structure is easy to process and convenient to assemble and disassemble.
