Document Type and Number:
Japanese Patent JP2005082128
Kind Code:
A
Abstract:

To provide an HST mounting structure for a working vehicle which can house HST in the interior of transmission cases (4, 5), can minimize the length of the transmission cases, can render the whole vehicle compact, and, by virtue of bridging of HST between left and right side walls within the transmission cases (4, 5), can stably support input and output shafts connected to HST and HST, does not hinder the flow of a lubricating oil filled into the transmission cases (4, 5), can prevent an increase in temperature of the oil or stagnation of impurities, and smoothly operate a transmission mechanism.

A pump case 1 of HST, a motor case 2, and a port block 3 interposed between both the cases are constructed integrally with each other. This integrated component is mounted, in a part near connecting parts 6, 7 of a clutch housing 4 and a transmission case 5 deviated toward either the clutch housing 4 side or the transmission case 5 side, while bridging between the left and right side walls within the case. An opening 8 for maintenance is provided on the upper face of the clutch housing 4 facing the outer peripheral part of the mounting flange 3, and a lid 9 is mounted in the opening 8.
