<p>The present invention relates to a transmission apparatus for a construction machine, which comprises: a swash plate installed in the casing of a driving unit to drive the construction machine, and supporting piston bodies coupled to a cylinder block movably in order to rotate the cylinder block of the driving unit; a gear shift part controlling the tilt angle of the swash plate against the cylinder block in order to change the driving speed of the construction machine; and a stopper to restrain the tilt angle of the swash plate in order to change the driving speed of the construction machine into the N (an integer larger than two) number of driving speeds. The transmission apparatus is capable of improving the work efficiency of the construction machine and realizing the various driving speeds of the construction machine.</p> |
