Abstract

The invention relates to an integrated crankshaft torsion damper assembly. The integrated crankshaft torsion damper assembly comprises a belt wheel and a hub connected with a crankshaft in a matched mode. The integrated crankshaft torsion damper assembly further comprises a damping rubber ring arranged between an inner circle of the belt wheel and an outer circle of the hub. The inner circle of the belt wheel is provided with a plurality of big inverted-trapezoid-shaped grooves of the same size at equal intervals. The outer circle of the damping rubber ring is provided with a plurality of biginverted-trapezoid-shaped bosses of the same size at equal intervals, and an inner circle of the damping rubber ring is provided with a plurality of small inverted-trapezoid-shaped grooves of the samesize at equal intervals. The outer circle of the hub is provided with a plurality of small inverted-trapezoid-shaped bosses of the same size at equal intervals. The multiple big inverted-trapezoid-shaped bosses of the outer circle of the damping rubber ring are matched with the multiple big inverted-trapezoid-shaped grooves in the inner circle of the belt wheel in a one-to-one correspondence modeand vulcanized into a whole. The multiple small inverted-trapezoid-shaped bosses of the outer circle of the hub are matched with the multiple small inverted-trapezoid-shaped grooves of the inner circle of the damping rubber ring in a one-to-one correspondence mode and vulcanized into a whole. The shear force borne by the damping rubber ring of the integrated crankshaft torsion damper assembly canbe changed into stress, the service life of the damping rubber ring is prolonged, and torsion vibration of the crankshaft is remarkably reduced.

Description

technical field [0001] The invention relates to an engine, in particular to an integral crankshaft torsional damper assembly in an engine crankshaft transmission. Background technique [0002] The function of the integral crankshaft torsional damper assembly is to transmit the crankshaft torque to water pumps, hydraulic pumps, generators and other components through the belt and drive them to work. Harm caused by the engine and reduce the vibration and noise of the vehicle. When the automobile engine is working, the magnitude and direction of the force acting on the crankshaft are periodically changed, and the crankshaft will produce torsional vibration due to the swing of the flywheel with a large moment of inertia; this torsional vibration will greatly affect the ride of the vehicle comfort, and even affect the operation of the entire power output and transmission system. Therefore, the integral crankshaft torsional damper assembly is now widely used in high-performance ...
