Embodiment Construction

[0046] Below, combine Figure 1 to Figure 8 Embodiments of the work machine according to the present invention are described, and then, in conjunction with figure 1 with Figure 12 to Figure 20 The second embodiment will be described. In all the embodiments, a combine harvester is used as an example of a work machine, and its overall side view is shared. figure 1 . Therefore, for figure 1 It is only described in the first embodiment, and will not be repeated in the second embodiment.

[0047] 1st form of implementation

[0048] figure 1 In the combined harvester shown, No. 1 is a pre-harvest processing device. This pre-harvesting treatment device 1 is carried out by lifting up the ear stalk of erect growth such as rice and wheat, handles the lifting device 1a, the clipper type harvesting device 1b that the ear stalk that lifts up is carried out harvesting process, and the ear stalk that will harvest The conveying device 1c etc. which convey to the rear of the body are ...

Abstract

PURPOSE: Provided is a miniaturized traveling transmission for working machines for transmitting engine power to right and left axles with engine speed changed by a static hydraulic type continuously variable transmission. CONSTITUTION: The working machine includes an engine; a static hydraulic type continuously variable transmission(30) with a pump unit(33) and a motor unit(34); a mission case(10) to receive the power speed changed by the static hydraulic type continuously variable transmission; right and left axles(13a,13b) positioned from right to left of the mission case; and a right and left traveling device operatively connected to each of the right and left axles, an input shaft(11) of the pump unit being operatively connected to an output shaft of the engine while the output shaft(31) of the motor unit being operatively connected to right and left axles is characterized in that the input shaft(11) of the pump unit and the output shaft(31) are installed extending parallel against the right and left axles and also are connected to a port block(32) to install a passage to contact the pump unit and motor unit, and a unit chamber(19) to receive the pump unit and the motor unit is installed inside the mission case.

Description

technical field [0001] The present invention relates to an engine, a hydrostatic continuously variable transmission device having a pump unit and a motor unit for shifting the power received from the engine, and receiving the transmission through the hydrostatic continuously variable transmission device. The gearbox body of the rear power, the left and right axles on the left and right sides of the gearbox body, and the left and right running gear working machines that are operatively connected to the left and right axles respectively, are placed on the output shaft of the engine An input shaft of the pump unit is linked to the upper side, and an output shaft of the motor unit is linked to the left and right axles. More specifically, it relates to the structure of the traveling power transmission device of this working machine. Background technique [0002] The above-mentioned running power transmission device is generally constructed in such a way that a hydrostatic contin...
