Abstract

Disclosed herein is a frame apparatus for an agricultural work vehicle. The frame apparatus includes: an engine frame configured to support the engine of an agricultural work vehicle; a front frame connected to each of a front work machine and the engine frame to support the front work machine mounted in front of the agricultural work vehicle; a center case spaced apart from the front frame based on a first axis direction, and disposed behind the engine frame; a rear axle case coupled to the rear of the center case; side frames each coupled to each of the front frame and the rear axle case on both sides of the agricultural work vehicle; and a crossbar coupled to the side frames while connecting the side frames on both sides based on a second axis direction perpendicular to the first axis direction.

First claim

What is claimed is:

1. A frame apparatus for an agricultural work vehicle, the frame apparatus comprising:
an engine frame configured to support an engine of an agricultural work vehicle;
a front frame connected to each of a front work machine and the engine frame to support the front work machine mounted in front of the agricultural work vehicle;
a center case spaced apart from the front frame based on a first axis direction, and disposed behind the engine frame;
a rear axle case coupled to a rear of the center case;
side frames each coupled to each of the front frame and the rear axle case on both sides of the agricultural work vehicle; and
a crossbar coupled to the side frames while connecting the side frames on both sides based on a second axis direction perpendicular to the first axis direction,
wherein the front frame, the engine frame, the center case and the rear axle case are arranged and coupled in order along the first axis direction,
wherein the crossbar is coupled to the side frames so that the crossbar is disposed behind the center case based on the first axis direction,
wherein the crossbar overlaps the side frames along the second axis direction and is coupled to both sides of the rear axle case,
wherein the crossbar is installed to overlap at least partly with a rear axle in the first axis direction.

2. The frame apparatus of claim 1 , wherein:
the crossbar comprises a first coupling member coupled to one of the side frames, a second coupling member coupled to a different one of the side frames, and a cross member coupled to each of the first coupling member and the second coupling member; and
a width of the cross member is formed to be larger than a width of the first coupling member based on the first axis direction.

3. The frame apparatus of claim 1 , further comprising reinforcing parts each coupled to both of the engine frame and one of the side frames;
wherein the reinforcing parts are disposed spaced apart from the crossbar based on the first axis direction.

4. The frame apparatus of claim 3 , wherein:
each of the reinforcing parts comprises a first reinforcing coupling member coupled to the engine frame, a second reinforcing coupling member coupled to one of the side frames, and a reinforcing connection member configured to connect the first reinforcing coupling member and the second reinforcing coupling member; and
the second reinforcing coupling member is disposed behind the first reinforcing coupling member based on the first axis direction.

5. A frame apparatus for an agricultural work vehicle, the frame apparatus comprising:
an engine frame configured to support an engine of an agricultural work vehicle;
a front frame connected to each of a front work machine and the engine frame to support the front work machine mounted in front of the agricultural work vehicle;
a center case spaced apart from the front frame based on a first axis direction, and disposed behind the engine frame;
a rear axle case coupled to a rear of the center case;
a side frame comprising a first side member and a second side member that are each coupled to each of the front frame and the rear axle case on either sides of the agricultural work vehicle; and
reinforcing parts disposed between the first side member and the second side member and the engine frame, and each coupled to each of the first side member and the second side member and the engine frame,
wherein the front frame, the engine frame, the center case and the rear axle case are arranged and coupled in order along the first axis direction,
wherein a first end of each of the first side member and the second side member is coupled to the front frame and a second end of each of the first side member and the second side member is coupled to the rear axle case,
wherein the reinforcing parts are extended along the first axis direction, a first end of each of the reinforcing parts is coupled to the engine frame and a second end of each of the reinforcing parts is coupled to one of the first side member and the second side member, and the first end of each of the reinforcing parts is positioned forward in the first axis direction compared to the second end of each of the reinforcing parts.

6. The frame apparatus of claim 5 , wherein:
each of the reinforcing parts comprises a first reinforcing coupling member coupled to the engine frame, a second reinforcing coupling member coupled to one of the first side member and the second side member, and a reinforcing connection member configured to connect the first reinforcing coupling member and the second reinforcing coupling member; and
the second reinforcing coupling member is disposed behind the first reinforcing coupling member based on the first axis direction.
