Embodiment Construction

[0015] Such as figure 1 and 2 As shown, a dual-mass flywheel assembly includes a spring, a flywheel driving disc 11, a positioning disc 10, a flywheel damping disc 3, a flywheel hub 4, a flywheel disc 5, a ring gear 19, a decorative ring 1 and a two-way limiter Bridge bearing 9. The flywheel driving disc 11 is riveted with the positioning disc 10, welded with the flywheel damping disc 3, and the flywheel damping disc 3 is welded with the decorative ring 1; the outer circle of the flywheel driving disc 11 is provided with a stop 21, and the ring gear 19 passes through the stop. The port 21 is closely connected with the flywheel driving disc 11; the outer circle of the flywheel driving disc 11 is covered with a fastening ring 2. Its flywheel disc 5, flywheel disc hub 4 and two-way limit bridge bearing compression ring 20 are riveted together by assembly rivets 8, and an assembly rivet pad 7 is set between the flywheel disc 5 and the assembly rivets 8. A friction washer 13, a ...

Abstract

The invention discloses a bidirectional flywheel assembly, which is characterized in that: a bidirectional limit gap bridge bearing is arranged between a flywheel disc hub and a flywheel driving disc; and an outer sleeve of the bidirectional limit gap bridge bearing is fixedly connected with an inner end of the flywheel disc hub and an inner sleeve of the bidirectional limit gap bridge bearing isfixedly connected with the flywheel driving disc. A vehicle with the bidirectional flywheel assembly can shift gears more stably without gaps, and the bidirectional flywheel assembly also has function of buffering and damping in the process of improving the speed. The bidirectional flywheel assembly has the advantages of prolonging the service life and improving the working safety.

Description

technical field [0001] The invention relates to a dual-mass flywheel assembly, which belongs to the technical field of auto parts manufacturing. Background technique [0002] The dual-mass flywheel appeared on automobiles in the late 1980s. The so-called dual-mass flywheel is to divide the original flywheel into two parts, and one part is kept on the side of the original engine for starting and transmitting the rotational torque of the engine. , called the primary mass. The other part is placed on the transmission side of the drive train to increase the moment of inertia of the transmission and is called the secondary mass. Since the secondary mass can increase the moment of inertia of the drive train without increasing the moment of inertia of the flywheel, the resonance speed can be reduced below the idle speed. For example, the dual-mass flywheel of the German Luke (LUK) company reduces the resonance speed from 1300 rpm to 300 rpm. At present, the idle speed of a gener...
