Torsion damping coupling for transmission assembly of hybrid system and connection method

Abstract

The invention discloses a torsion damping coupling for transmission assembly of a hybrid system and a connection method. The torsion damping coupling comprises a torque damper and rigid coupling plates, the torque damper is in a double-spring damping structure, a plurality of spring mounting notches are circumferentially distributed on the end face of a spline hub, damping springs are mounted in the spring mounting notches in a large spring and small spring staggered arrangement manner, the center of the spline hub is provided with a spline hole and used for being sleeved on a coupling shaft of a part at the rear end of an engine, and the rigid coupling plates are attached to two end faces of the spline hub respectively. The end faces of two torsion damping plates and the end face of the spline hub are correspondingly provided with torsion damping plate spring mounting notches, and small parts of the damping springs mounted in the spline hub spring mounting notches are clamped in the torsion damping plate spring mounting notches. The large damping springs and the small damping springs are used for damping in torque fluctuation when the engine outputs power, so that the torque fluctuation can be effectively absorbed.

Description

technical field [0001] The invention relates to a torsional shock-absorbing coupling for a hybrid electric vehicle, in particular to a torsional shock-absorbing coupling and a connecting method for a power system transmission assembly of a hybrid electric vehicle, through which the torsional shock-absorbing coupling The converter can effectively reduce the output torque fluctuation of the engine, thereby reducing the impact of the transmission parts at the rear end of the transmission chain. Background technique [0002] Since the 1990s, the problems of energy crisis and environmental pollution have been paid more and more attention by the governments and people of various countries. In 2010, China's automobile production has exceeded 17 million, and the number of automobiles is growing rapidly. It is estimated that by 2020, the number of automobiles will exceed 200 million. According to the current level of automobile fuel economy, the annual fuel consumption of vehicles wi...
