Problems solved by technology

[0009] However, in the half-feed combine harvester, high straightness is required at the time of ridge harvesting, that is, straight operation
However, the above-mentioned left and right independent power transmission devices have the following problems: regardless of whether the combine harvester has been operated straight ahead, that is, regardless of whether the left and right travel devices need to be at the same number of revolutions, individual differences between the left and right power transmission devices , the difference in power transmission loss, the oil leakage caused by the load applied to the left and right traveling devices, etc., resulting in a difference in the number of revolutions of the left and right traveling devices and causing the combine harvester to produce a steering action
[0011] However, in the case of providing a parking brake mechanism for the power transmission device, if the power transmission device is a left and right independent type, it is necessary to provide a parking brake mechanism for each of the left and right power transmission devices, and there is a problem that the power transmission device is correspondingly large. the problem of

Abstract

The invention provides a power transmission device, which is highly straight in running performance when being operated in a straight mode, is capable of turning smoothly during a turning operation and has a compact structure. The power transmission device comprises: a first continuously variable mechanism and a second continuously variable mechanism, which can transmit power from an engine at variable speeds; a first transmission mechanism, which can transmit power from the first continuously variable mechanism to running apparatuses; a second transmission mechanism, which can transmit powerfrom the second continuously variable mechanism to the running apparatuses; and a transmission box, which accommodates the first transmission mechanism and the second transmission mechanism. The firstcontinuously variable mechanism is arranged on one of the left side and the right side of the transmission box, and the second continuously variable mechanism is arranged on the other side of the transmission box. The first transmission mechanism and the second transmission mechanism can transmit power from the first continuously variable mechanism and the second continuously variable mechanism separately to the left and right running apparatuses.

Description
