Abstract

The invention aims to design a gear box body of riding-type moving vehicle to separate an oil box section completely from a gear box body section, thus not only reducing the weight but also preventing the quality deterioration of oil consumed by hydrostatic stepless transmission (HST) device. The riding-type moving vehicle of the invention can change the speed of the rotation force of a motor (12) by the HST device and a gear speed-changing device in the gear box body (11) and transmit the force to moving wheels (6, 7), and is characterized in that the gear box body (11) is made into a structure with a partition wall (11c) separating the oil box section (11d) completely from the gear box body section (11e) and into the structure divided by the division surfaces connecting the gear box body section (11e) and the oil box section (11d) on the same plane; and the oil tank section (11d) is used for supplying oil to or discharging oil from the HST device.

Description

technical field [0001] The present invention relates to a passenger vehicle for agricultural machinery such as a passenger rice transplanter, a harvester, and a tractor. Background technique [0002] In the agricultural machinery that is equipped with the working machine at the rear of the mobile body with a pair of left and right front wheels and rear wheels, and is provided with a steering wheel for steering the left and right front wheels on the front side of the mobile body, it is known that: The box body is arranged on the front side of the mobile body, and the transmission box is provided with a plurality of transmission shafts whose axes are located in the left and right directions. The steering shaft rotated by the steering wheel is inserted into the box from the upper part of the transmission box. body and pass through the gearbox case and protrude from its bottom, and the steering shaft is arranged on the rear side of the drive shaft in the left and right direction...
