Example Embodiment

[0046] Below, combine Figure 1~Figure 8 The implementation form of the working machine according to the present invention will be described, and then combined figure 1 with Figure 12 ~ Figure 20 The second embodiment will be described. In all the implementation forms, as an example of the working machine, the combine harvester is used for description, and the overall side view is shared figure 1 . Therefore, for figure 1 It will only be described in the first embodiment, and will not be repeated in the second embodiment.

[0047] First implementation form

[0048] figure 1 In the combine harvester shown, number 1 is the pre-harvesting processing device. The pre-harvesting processing device 1 is composed of a raising device 1a for raising up the stalks of rice and wheat, etc., a push-cutting type harvesting device 1b for harvesting the raised stalks, and the stalks to be harvested. The conveying device 1c that conveys to the rear of the machine body is configured. The convey...

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...
