Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0024] Such as Figure 1-Figure 3 As shown, the embodiment of the present invention provides a magnetic damping pulley, including a pulley 1 and a hub 2 set inside the pulley 1, the pulley 1 and the hub 2 can rotate relatively, and a first magnet is arranged between the pulley 1 and the hub 2 and a second magnet;

[0025] When the wheel hub 2 rotates, first the first magnet is pushed to rotate, and then the first magnet pushes the second magnet to rotate through repulsive force, and the second magnet then pushes the belt pulley 1 to rotate.

[0026] Wherein, between the first magnet and the second magnet and the pulley 1 and the hub 2 can be such as figure 2 The connection relationship shown in , can also be as image 3 The connection relationship...

Abstract

The invention discloses a magnetic damping belt pulley. The magnetic damping belt pulley comprises a belt pulley and a hub sleeved in the belt pulley, wherein the belt pulley and the hub can rotate relative to each other; a first magnet and a second magnet are arranged between the belt pulley and the hub; when the hub rotates, the first magnet is pushed to rotate at first; then the first magnet pushes the second magnet to rotate through the action of a repulsive force; and the second magnet further pushes the belt pulley to rotate, equivalently, the torque of the belt pulley or the hub is conveyed via the magnetic effect between the magnets. Therefore, the problems of small resistance, poor stability and short service life of a damping belt pulley at present are solved.

Description

technical field [0001] The invention relates to automobile transmission components, in particular to a magnetic force damping belt pulley. Background technique [0002] When the engine is working, the crankshaft is under the action of periodically changing torque, and the phenomenon of periodic relative torsion between the crankshafts is called torsional vibration, referred to as torsional vibration. The vibration of the engine is related to its life, work efficiency and impact on the surrounding environment. The vibration of the crankshaft system is an important factor that causes the vibration of the internal combustion engine. For this reason, the engine is equipped with a vibration-absorbing pulley. On the one hand, it can reduce the torsional vibration of the crankshaft, reduce the stress level of the crankshaft, and improve the fatigue life of the crankshaft; in addition, it can transmit torque, attenuate torque fluctuations, and ease the impact load on the front-end ...
