AI Technical Summary

Technical Problem

Conventional disconnector devices for vehicles have complex structures that increase vehicle length, occupy space, and cause noise and vibration due to high differential issues, particularly in two-wheel drive mode.

Method used

A disconnector device with a modular actuator system that includes a first and second clutch ring, a sleeve, and an actuator device to engage clutch portions for four-wheel drive and differential limitation, reducing complexity and eliminating the need for a disconnector shaft.

Benefits of technology

The solution simplifies assembly, reduces vehicle length and weight, minimizes noise and vibration, and enhances packaging and versatility by eliminating unnecessary parts, while enabling efficient power transmission between two-wheel and four-wheel drive modes.

Abstract

To provide a disconnector device in which either, a first clutch part of a first clutch ring is engaged with a third clutch part of a case according to a first operation of a sleeve, so that four-wheel drive is performed, or a second clutch part of a second clutch ring is engaged with a fourth clutch part of one-side side gear in an engaged state of the first clutch part and the third clutch part, according to a second operation of the sleeve, so that differential limitation is performed.SOLUTION: A disconnector device comprises: a case; a first clutch ring provided with a first clutch part on an outer diameter part; and a second clutch ring whose one-side end is coupled to the first clutch ring, and which is provided with a second clutch part at one side toward a one-side side gear mounted inside the case, and in which the sleeve is bonded to the other-side outer diameter part.SELECTED DRAWING: Figure 1
