Abstract: PURPOSE: A device for switching 2/4 wheels drive in part time is provided to prevent differential by connecting/isolating a differential shaft and an axle shaft through a cable and a transfer lever. CONSTITUTION: A 2/4 wheels drive switching device in part time comprises two sleeves transmitting/isolating power by being arranged between a differential shaft(52) and an axle shaft(54); a driving unit operated by a transfer lever(T) by being mounted in a differential case to actuate the sleeves at the same time; a hinge lever(3) rotating by being combined to the differential case by a hinge; and an equalizer(4) installed on a cable(5) by being connected to the sleeves. The cable rotates the hinge lever by pulling the transfer lever to operate the sleeves. The equalizer equalizes force applied to the sleeve while pulling the transfer lever. Thereby, the 2/4 wheels drive switching device in the part time prevents differential by connecting/isolating the differential shaft and the axle shaft through the cable and the transfer lever. Moreover, the 2/4 wheels drive switching device in the part time removes noise and vibration by isolating the power on the axle shaft.

Abstract: PURPOSE: A clustering web geographic information system based on a vector and a method for controlling the same are provided to enhance a performance of a clustering web geographic information system server by performing an effective load distribution using a load distributing processor. CONSTITUTION: A client(10) downloads a page of a web server(20) through a web browser, communicates with a corresponding control server or an applet server using an HTTP, receives vector data of a user-wanted area, and outputs the data on a screen. The web server(20) transmits all space queries being entered from an object downloaded in the client(10) to a load distributing processor(30). A progressive transmission processing unit(70) extracts an important point of each object for minimizing a response of a user and transmits the point before transmitting the vector data processed from a GIS(Geographic Information System) server(40) to the client(10) through the web server(20). A clustering device(50) distributes a service request from the client(10) among many GIS servers, and enhances a processing performance. The GIS server(40) stores a GIS engine, receives/processes a space query of the client(10) from the load distributing processor(30), and transmits a processed result to the progressive transmission processing unit(70). A space/non-space database(60) supplies data to the GIS server(40), manages entire data, and constitutes a local copy database to the GIS server(40) for preventing a bottleneck phenomenon.
