Problems solved by technology

A detailed description is not given here, but when the guide 125 reaches the vicinity of the left push-pull rod 106L or the right push-pull rod 106R, a difference is generated between the amount of movement of the left push-pull rod 106L and the movement amount of the right push-pull rod 106R
[0016] The above-mentioned transmission 113 has a complicated and bulky structure due to including pivot shafts 124, 124, guides 125, shaft 115, control rocker arm (mixing lever) 122 and other components.
Fitting a complex and large transmission 113 on a small vehicle would make the vehicle more expensive and larger

Abstract

A hydraulically driven vehicle is disclosed which is moved or turned by driving left and right hydraulic transmissions with one engine and driving left and right drive wheels with these hydraulic transmissions. The vehicle includes a gear-shifting mechanism for converting the actions of an operator and transmitting the result to the hydraulic transmissions, which mechanism is comprised of a first swinging member that is swung by a vehicle speed cable, and left and right second swinging members that are placed on the first swinging member, that are swung by left and right steering cables, and that push and pull push-pull rods.

Description

technical field [0001] The present invention relates to a hydraulically driven vehicle, wherein left and right hydrostatic transmissions are driven by an engine, and left and right drive wheels are driven by these left and right hydrostatic transmissions. Background technique [0002] The hydrostatic transmission is equipped with variable capacity swash plate hydraulic pumps and hydraulic motors. When the swash plate hydraulic pump is driven by the engine, the pump generates high-pressure working oil. When this high-pressure hydraulic oil is supplied to the hydraulic motor, the hydraulic motor rotates. The drive wheels can be turned by hydraulic motors. [0003] The engine works continuously at a constant speed. The rotational speed of the input shaft of the swash plate type hydraulic pump is constant, but the amount of working oil injected can be changed by changing the inclination angle of the swash plate from the outside. The hydraulic motor can be rotated normally, s...
