TRANSMISSION AND CONSTRUCTION MACHINES HAVING THE SAME
The present invention relates to a transmission for construction equipment and construction equipment having the same. The transmission comprises: a body having a moving hole wherein a working fluid to change a driving speed of the construction equipment moves; a spool coupled to the body to be moved; a discharge unit for discharging the working fluid which passes through the spool to the outside of the body; and a notch groove formed in the spool to reduce a distance that the working fluid discharged from the moving hole reaches the discharge unit by passing through the spool as the spool moves toward the discharge unit. According to the present invention, a discharge amount of working fluid is controlled in accordance with a transmission time using the notch groove wherein a working fluid moving distance is controlled.
