Problems solved by technology
[0003] Due to the limited layout space of the inner cavity of the dual-mass flywheel, it is difficult to completely solve the problem of abnormal knocking noise and vibration at low temperature and low speed by optimizing the internal structure of the flywheel. This problem has also become a major supplier of dual-mass flywheels and most hosts using dual-mass flywheel Common problems in factories, it is often necessary to slow down abnormal noise at low temperature by adjusting idle speed and sacrificing idle fuel consumption and emissions
[0004] In the prior art, there is a diesel engine low-temperature heating system (the publication number is CN106401834A), which is used for auxiliary heating when the diesel engine is cold-started at low temperature, so as to improve the viscosity and fluidity of diesel oil at low temperature, so that it can burn fully and ensure The smooth start-up and normal operation of the diesel engine, due to the limited layout space of the dual-mass flywheel cavity, does not apply to the above-mentioned patents, and it is necessary to design a corresponding solution for the structural characteristics of the dual-mass flywheel

Abstract
The invention discloses a dual-massflywheel heating device and a transmission system provided with the heating device, and relates to the technical field of transmission systems. The outer cavity of the spring chamber of the flywheel; the brush guide rail, which is used to be arranged on the outer ring of the spring chamber, and the brush guide rail is a ring structure; two brush coils embedded in the outer ring of the brush guide rail; slidingly arranged on the electric Brushes on a brush rail; wherein a plurality of heating elements are electrically connected to the brushes via two brush coils. The invention utilizes a plurality of heating components to heat the spring cavity, thereby reducing the viscosity of the grease inside the dual-massflywheel, avoiding the impact on the damping performance, and providing guarantee for the normal operation of the dual-mass flywheel.
Description
technical field [0001] The invention relates to the technical field of transmission systems, in particular to a dual-mass flywheel heating device and a transmission system with the heating device. Background technique [0002] With the improvement of environmental protection and emission regulations, the miniaturization and high efficiency of engines have become a development trend. In the process of power transmission, the increase of engine power and torque will inevitably increase the output vibration excitation. If better vibration reduction measures are not taken, the comfort of the whole vehicle will be seriously reduced. Matching an efficient damping mechanism has become an urgent need. Among the existing technical means, the dual-mass flywheel is currently the most effective damping mechanism. Although it is gradually becoming popular in the market, it still belongs to a relatively new technology. In terms of reliability and NVH (Noise, Vibration, Harshness, that is...
