Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
The embodiment provides a dual mass flywheel of integrated multistage damping system, and the dual mass flywheel that this scheme provided can adapt to that the engine torsional vibration is little and the big two kinds of different operating modes of engine torsional vibration, promotes the passenger and to the travelling comfort requirement when putting in order the car.
In the scheme, referring to fig. 1-6, the proposed dual mass flywheel comprises a main flywheel 10 and an auxiliary flywheel 20; the main flywheel 10 is used for being connected with a crankshaft in a transmission mode, the auxiliary flywheel 20 is connected with a clutch transmission device, a bearing seat 11 is fixed on the main flywheel 10, and the bearing seat 11 protrudes upwards and is arranged coaxially with the main flywheel 10; specifically, the main flywheel 10 of the scheme is a disc-shaped body with a central axis, and the bearing seat 11 is installed at the central position of the main flywheel 10 and is coaxially fixed through rivets; the bearing seat 11 is arranged to facilitate stable installation between the main flywheel 10 and the auxiliary flywheel 20, and simultaneously facilitate the matching installation of the primary damping structure and the secondary damping structure.
The stable installation between the main flywheel 10 and the auxiliary flywheel 20 is realized by the matching installation of a rotating bearing and a bearing seat 11; specifically, a cavity is formed at the lower end of the auxiliary flywheel 20, and a rotating bearing 21 is clamped in the cavity; the auxiliary flywheel 20 is sleeved on the bearing seat through a rotating bearing 21.
Meanwhile, referring to fig. 1 to 8, a coaxial shift fork 30 is further provided between the main flywheel 10 and the auxiliary flywheel 20 and the shift fork 30 is fixed on the auxiliary flywheel 20 by a rivet; the fork 30 here has internal teeth; a primary damping structure and a secondary damping structure are fixedly sleeved on the bearing seat 11; wherein, the first-stage damping structure is provided with a first vibration damping piece 41, the outer end surface of the first vibration damping piece 41 is provided with outer teeth, and the first vibration damping piece 41 and the shifting fork 30 are in a complete meshing state; the second-stage damping structure is provided with a second vibration damping piece 51, outer teeth are arranged on the outer end face of the second vibration damping piece 51, and the second vibration damping piece 51 and the shifting fork 30 are in a clearance meshing state.
It can be understood that the dual mass flywheel in the present scheme can be suitable for two different working conditions (a small engine torsional vibration working condition and a large engine torsional vibration working condition), and is mainly realized by the first vibration damping part 41 and the second vibration damping part 51 which are designed here; the first vibration damping member 41 and the shifting fork 30 are in a complete meshing state, and under the meshing transmission, as long as the first vibration damping member 41 is in a rotating moment, the shifting fork 30 can synchronously and instantaneously rotate so as to drive the auxiliary flywheel 20 to rotate; of course, only the first vibration damping member 41 and the shift fork 30 are in a complete engagement state, and only the working condition of small engine torsional vibration can be applied, and when the engine torsional vibration is large, the second vibration damping member 51 is required to be matched.
Specifically, the second vibration damping member 51 is in a gap engagement state with the shift fork 30, and it can be understood that the external teeth of the second vibration damping member 51 are small, and a large engagement gap is formed between the external teeth of the shift fork 30, so that the second vibration damping member 51 can be driven to rotate to generate damping torque only when the shift fork 30 rotates by a certain angle.
By combining the working principles, when the torsional vibration of the engine is small in the idling and normal running processes of the whole vehicle, the first vibration damping part 41 and the shifting fork 30 are in a meshed state, and finally the main flywheel 10 drives the auxiliary flywheel 20 to rotate; however, when the engine torsional vibration is large during ignition starting or all-rapid acceleration and rapid deceleration of the whole vehicle, the first vibration damping part 41 and the shifting fork 30 are still in a complete meshing state, and because the torque fluctuation is large, the shifting fork 30 can also rotate by a certain angle until the shifting fork is in contact meshing with the external teeth of the second vibration damping part 51; the shifting fork 30 at this time is engaged with the first vibration damping part 41 and the second vibration damping part 51 for transmission, and deals with the working condition of large torsional vibration of the engine under the combined action of a secondary damping system (a primary damping structure and a secondary damping structure).
In order to further refine the structure of the present solution, the primary damping structure and the fixture structure of the primary damping structure are described in detail below.
In this scheme, the primary damping structure further includes a first vibration damping disc spring 42 sleeved on the bearing seat 11, the first vibration damping disc spring 42 is configured to abut against an end surface of the first vibration damping member 41 to provide an axial force F1 to the first vibration damping member 41, and the axial force F1 acts on the first vibration damping member 41 to enable the first vibration damping member 41 to generate a friction damping torque to cope with a working condition of small torsional vibration of the engine.

Similarly, the axial force F2 is transmitted to the second vibration damping member 51 through the stopper damper 53, and the second vibration damping member 51 generates a frictional damping torque to cope with a condition in which the engine torsional vibration is large.
Meanwhile, in the scheme, the stop damping piece 53 is only designed in the secondary damping structure, but not in the primary damping structure, so that the design is to improve the integration degree of the damping system, the stop damping piece is eliminated in the primary damping structure, the first vibration reduction disc spring 42 is directly abutted to the end face of the first vibration reduction damping part 41 and rotates along with the end face, and the axial size of the whole dual-mass flywheel is reduced by 2-3 mm while stable axial pressure is guaranteed to be provided.
In this scheme, in order to ensure the rationality of the structural design of the whole dual mass flywheel, the axial force F1 and the axial force F2 described above are opposite in direction, and the axial force F1 is less than the axial force F2. It will be appreciated that the frictional damping torque generated by the abutment of the first damping disc spring 42 against the first damping member 41 will be less than the frictional damping torque generated by the second damping disc spring 52 acting on the second damping member 51. Only by the design, the friction damping torque generated by the axial force F1 can adapt to the working condition of small torsional vibration of the engine, and the friction damping torque generated by the axial force F1 and the axial force F2 jointly adapts to the working condition of large torsional vibration of the engine.
Optionally, the first damping disc spring 42 provides an axial force F1 generally in the range of 50N-150N; the axial force F2 provided by the second damping disc spring 52 is typically 500N-1500N.
