Abstract

The invention discloses a crankshaft pulley assembly. The crankshaft pulley assembly comprises a belt pulley, a first friction piece, damping rubber, a hub, a second friction piece and a signal disc.The belt pulley is connected with the hub through the damping rubber. The hub of the belt pulley is equipped with the signal disc in a press fitting manner. The signal disc is provided with a gap tooth. The signal disc with the gap tooth rotates in sync with a crankshaft in order to provide a rotating speed signal to an engine. The first friction piece and the second friction piece are installed between the belt pulley and the signal disc and respectively mounted on the belt pulley and the signal disc. With the crankshaft pulley assembly, the torsion angle of the engine crankshaft is reduced.The rotation speed of the engine can be read. Larger angular displacement is allowed between the belt pulley and the hub. Meanwhile, belt output is more stable. The crankshaft pulley assembly has features of simple structure and high product integration degree. In the meantime, the fluctuating output rotating speed of the belt pulley is reduced.

Description

technical field [0001] The invention relates to a crankshaft pulley assembly and belongs to the technical field of auto parts. Background technique [0002] The integration of various components on today's engines is getting higher and higher, and there are more and more accessories driven by belts, and those accessories driven by belts have stricter requirements on the stability of the rotational speed. During the operation of the engine crankshaft, due to the specific working conditions of each cylinder taking turns to do work at a certain rotation angle, the engine crankshaft has torsional vibration and speed fluctuations during operation, which will cause the crankshaft pulley connected to the engine shaft to also There will be a phenomenon of unstable speed, which will cause the belt to slip, resulting in the occurrence of unstable speed of the belt drive accessories. Contents of the invention [0003] The technical problem to be solved by the present invention is to...
