Benefits of technology

The present invention allows for the positioning antenna to be installed on the roof of a vehicle while maintaining accurate positioning and preventing the effects of vibrations. Its technical effects include improved positioning accuracy and stability of the vehicle.

Problems solved by technology

In the case where the work vehicle is a bulldozer, in performing operations such as dozing and grading, the work implement is subjected to great vibrations, which decrease a positioning accuracy of the GNSS antenna disposed on the work implement.
When the work implement is subjected to vibrations, the pole may vibrate, and an antenna cable connected to the GNSS antenna may contact earth or sands.

Embodiment Construction

[0027]Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0028]With reference to FIG. 1, a bulldozer 30, which serves as a work vehicle of the present invention, mainly includes a cab 1, an engine compartment 34, a hydraulic oil tank module 35, a pair of track frame modules 37, and a dozing blade 38. Cab 1 is a box-shaped structure which forms an interior room space for an operator OP operating bulldozer 30 to enter. With reference to FIG. 2, bulldozer 30 further includes a vehicle frame 31, an engine 32, an engine cooling module 33, and a fuel tank module 36.

[0029]Vehicle frame 31 has a front end and a rear end. Cab 1 is mounted on vehicle frame 31 between the front end and the rear end of vehicle frame 31. Cab 1 is equipped with a seat for operator OP to sit on, a manipulation mechanism such as a pedal and a lever, and an instrument panel or the like. Operator OP boards cab 1 to drive bulldozer 30 and operate dozing blade 38. In th...

Abstract

Provided is a work vehicle in which a positioning antenna can be installed above a roof plate of a cab at an accurate position and in a proper attitude while preventing a positioning accuracy from being decreased by vibrations. The work vehicle includes a first mount member, a second mount member and a positioning antenna. The first mount member includes a left-side member fixed on the roof beam at the left side and a right-side member fixed on the roof beam at the right side. The second mount member is disposed above the roof plate across the left-side member and the right-side member. The positioning antenna is mounted on the second mount member.

Description

TECHNICAL FIELD[0001]The present invention relates to a work vehicle, and in particular, relates to a work vehicle equipped with a cab to be boarded with an operator.BACKGROUND ART[0002]Information-and-Communication-Technology intensive constructions have been performed on a work vehicle having a work implement by using a satellite navigation system to determine a position of the work implement in real time so as to improve work efficiency thereof. Conventionally, there has been disclosed a work vehicle which has a pole disposed on an upper edge of a work implement, and on an upper end of the pole, a GNSS (Global Navigation Satellite System) antenna is installed (for example, see Japanese Patent Laying-Open No. 10-38570 (PTD 1)).[0003]In the case where the work vehicle is a bulldozer, in performing operations such as dozing and grading, the work implement is subjected to great vibrations, which decrease a positioning accuracy of the GNSS antenna disposed on the work implement. When ...
