Benefits of technology

The patent aims to prevent vibrations in a particular part of an engine, called the side plate. This vibration can be caused when the side plate is attached to the vehicle body frame, and it can be difficult to suppress. The goal of the invention is to reduce or prevent this vibration in the side plate of a bulldozer.

Problems solved by technology

As a result, it is easy for vibrations to be generated in the side plate.

Embodiment Construction

[0028]A side view of a bulldozer 1 according to a first embodiment of the present invention is shown in FIG. 1. The bulldozer 1 is provided with a travel device 2, a vehicle body 3, and a work implement 4. The travel device 2 is a device for traveling the vehicle and has crawler tracks 11. The bulldozer 1 travels by the crawler tracks 11 being driven.

[0029]The vehicle body 3 includes a vehicle body frame 10 (refer to FIG. 6), a cab 12, an engine cover 13, and a cooling device 14. The cab 12 is supported by the vehicle body frame 10. The engine cover 13 is disposed in front of the cab 12. An engine 5 is installed in the engine cover 13. The upper surface of the engine cover 13 is inclined downward with a forward inclination. The cooling device 14 is disposed behind the cab 12. The cooling device 14 includes, for example, a radiator which cools cooling liquid in the engine 5 and an oil cooler which cools hydraulic fluid.

Abstract

A bulldozer includes a cab, a vehicle body frame supporting a cab and an engine cover. The engine cover has a side plate that has a rear edge with first and second rear edges. The second rear edge is a positioned above the first rear edge. The side plate has a first planar portion which includes the first rear edge and a second planar portion which includes the second rear edge. The side plate has a bent shape between the first and second planar portions. A ridgeline is disposed between the first and second planar portions and spans from the upper edge to the rear edge of the side plate. The side plate includes an attachment section which is attached to a vehicle body frame. The attachment section is positioned in the first planar portion adjacent to an intersection of the ridgeline and the rear edge of the side plate.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Japanese Patent Application No. 2012-177673 filed on Aug. 10, 2012, the disclosure of which is hereby incorporated herein by reference in its entirety.BACKGROUND[0002]1. Technical Field[0003]The present invention relates to a bulldozer.[0004]2. Background Information[0005]A bulldozer is provided with an engine cover which is disposed in front of a cab. The engine cover has a side plate and the side plate is attached to a vehicle body frame. For example, in a bulldozer which is disclosed in Japanese Laid-open Patent Application No. 2005-113674, the engine cover is mounted onto the vehicle body frame. Since the bottom edge of the side plate is disposed close to the vehicle body frame in this type of bulldozer, it is normal for the side plate to be attached to the vehicle body frame in the vicinity of the bottom edge.SUMMARY[0006]The side plate is a portion in the engine cover where the area is comparative...
