AI Technical Summary

Technical Problem

In existing hybrid vehicles, the eccentric connection between the engine and the motor leads to eccentric noise and bearing wear failure. Torque-limiting dampers generate knocking noise during torque switching, and straight-spoke spring dampers lack eccentricity adjustment function.

Method used

Design a vibration damper comprising a central disc hub and spoke spring buffer components. The spoke springs elastically deform in the circumferential and radial directions to compensate for eccentricity, and combined with a flexible disc to absorb axial vibration. The components are fixedly connected by bolts or rivets to achieve torsional limiting and eccentricity compensation.

Benefits of technology

It effectively avoids eccentric noise and bearing wear, reduces knocking noise, improves the stability and durability of the transmission system, and has a simple structure and low cost.

Abstract

The present application relates to a kind of damper and transmission system.The damper includes center hub and spoke spring buffer.The spoke spring buffer is arranged at the outer circumferential side of the center hub;The spoke spring buffer includes: outer ring part and multiple spoke springs;The outer ring part is arranged at the outer circumferential side of the center hub;Multiple spoke springs are respectively connected between the center hub and the outer ring part along the radial direction and are spaced along the circumferential direction, and multiple spoke springs can be elastically deformed to allow the center hub to move relative to the outer ring part.The damper of the present application can realize larger eccentric compensation function, can absorb axial vibration, and can reduce noise;In addition, the damper of the present application is simple in structure, and low in cost.
