Abstract
The utility model relates to a double mass flywheel, belonging to the automotive parts technology field, which is characterized in that a primary flywheel subassembly is firmly riveted with a retaining pin, the primary flywheel subassembly comprises a damping spring and is slidably connected with the damping spring, the damping spring is slidably connected with the end surface of a spring seat, the damping spring, the spring seat and a damping disc shifting fork are mutually slidably connected, a large disc cushion and the damping disc are firmly riveted with a secondary flywheel, the damping disc is slidably connected with the retaining pin, the primary flywheel subassembly is tightly connected with a bearing support through a bolt, the bearing support and the bearing are mutually the interference fit and the bearing and the secondary flywheel are mutually the interference fit, and the crankshaft connecting position of the primary flywheel subassembly is provided with a bended claw. The beneficial effect of the utility model is that the double mass flywheel can reduce the natural frequency of the speed changer vibration system of the engine in order to avoid the resonance at the idle speed; the utility model has the advantages of the good damping effect , the small rotary inertia, the easy gear shift, simplifying the flywheel structure and reducing the vibration noise.
Description
Technical field:
The utility model belongs to technical field of automobile components.
Background technique:
At present, at the motor of automobile---the flywheel existing structure that uses between the speed changer processes as cast iron, does not structurally have any damping property.And vibration damper is arranged in the driven disc of clutch, because structural limitations vibration damper distribution diameter is less, cause the little rigidity of vibration damper corner big, have two aspects limitation on the damping property: 1, it can not make motor---and the natural frequency of speed changer vibration system is reduced to below the idling speed, therefore can not avoid the resonance when idling.2, it is difficult to by reducing shock-absorbing spring rigidity to obtain bigger effectiveness in vibration suppression in the practical speed range of motor.
Summary of the invention:
Technical problem to be solved in the utility model is:
Provide a kind of idling not have resonance, good damping result ground double mass flywheel.
The technical solution of the utility model is:
Elementary divided flywheel assembly and stop pin riveted fixing, containing shock-absorbing spring in the elementary divided flywheel assembly is slidingly connected, shock-absorbing spring, spring seat end face are slidingly connected, be slidingly connected between shock-absorbing spring, spring seat and the damping disk(-isc) shift fork, video disc pad, damping disk(-isc) and secondary flywheel riveted fixing, damping disk(-isc) and stop pin are slidingly connected, elementary divided flywheel assembly connects by bolton with bearing support, be interference fit between bearing support and bearing, bearing and the secondary flywheel, be provided with curved pawl at the bent axle connection part of elementary divided flywheel assembly.
The beneficial effects of the utility model are:
Can reduce the natural frequency of motor-speed changer vibration system, to avoid the resonance when the idling; Its good damping result, rotary inertia is little, and gear shift is easy; Simplified flywheel structure; Reduced vibration noise.
Description of drawings:
Fig. 1 is an elementary divided flywheel assembly structure chart of the present utility model;
Fig. 2 is a double mass flywheel sectional view of the present utility model.
Wherein: the 1st, shock-absorbing spring, the 2nd, elementary divided flywheel assembly, the 3rd, video disc pad, the 4th, damping disk(-isc), the 5th, secondary flywheel, the 6th, bearing, the 7th, bearing support, 8 curved pawls, the 9th, stop pin, the 10th, spring seat, the 11st, damping disk(-isc) shift fork.
Embodiment:
Be described further below in conjunction with 1,2 pairs of the utility model of accompanying drawing:
Working principle of the present utility model is elementary divided flywheel assembly and the ratio of secondary Rotary Inertia of Flywheel approaches 1, and because the shock-absorbing spring distribution radius is bigger, can select for use the lower shock-absorbing spring of rigidity to realize big torsional oscillation corner, the torsional oscillation corner is to have flywheel now more than ten times, therefore the natural frequency of motor-speed changer vibration system can be reduced greatly.
Working procedure of the present utility model is: its vibration damper mainly is made up of elementary divided flywheel assembly, torsional vibration damper and secondary flywheel, elementary divided flywheel assembly is fastened on the bent axle by curved pawl, during engine operation, elementary divided flywheel assembly rotates, shock-absorbing spring promotes damping disk(-isc) shift fork rotation (damping disk(-isc) and the riveted joint of secondary flywheel) after starting working and reaching certain torque, thereby the secondary flywheel rotates output torque; Owing to torsional vibration damper (resonance when preventing idling and work operating mode) is arranged at elementary divided flywheel assembly, so the vibration damper of original structure clutch driven disc assembly is cancelled, simplify the structure, thereby make the clutch rotary inertia little, gear shift is easy.
