The machine 100 also includes a work implement 110 coupled at a front end of the machine 100, respectively. The work implement 110 is embodied as a blade. Further, the machine 100 may also include another work implement, such as, a ripper coupled at a rear end of the machine 100. Further, an engine (not shown) is mounted on the main frame 102 for providing propulsion power to the machine 100. More particularly, the engine is mounted within an enclosure 112 formed in the main frame 102. The engine may be an internal combustion engine such as a compression ignition diesel engine, but in other embodiments the engine might include a gas turbine engine.
The machine 100 includes a radiator guard assembly 114. A radiator (not shown) is mounted within the radiator guard assembly 114. The radiator is mounted proximal to the engine for engine cooling purposes. The radiator is protected from contact of dust and debris by the radiator guard assembly 114. The radiator guard assembly 114 will now be explained in detail with reference to FIGS. 2 to 5. Referring to FIGS. 2 and 3, the radiator guard assembly 114 is coupled to the main frame 102. More particularly, the radiator guard assembly 114 is coupled to a first side rail 116 and a second side rail 118 of the main frame 102. Further, each of the first and second side rails 116, 118 define an upper surface 120, 122, respectively. The radiator guard assembly 114 is swingably mounted to the main frame 102 at pivot points P1, P2 (shown in FIG. 3), respectively, such that the radiator guard assembly 114 can swing about the pivot points P1, P2 to allow access to the radiator.
Referring now to FIG. 4, the radiator guard assembly 114 includes an aperture plate 124. The aperture plate 124 allows air to flow towards the radiator, via a fan that is mounted to the aperture plate 124. The aperture plate 124 is generally square shaped and includes a centrally disposed opening 126. The opening 126 is circular in shape, however, the opening 126 may include any other shape, based on application requirements.
The radiator guard assembly 114 also includes a first side sheet 130 and a second side sheet 132. The first side sheet 130 is similar to the second side sheet 132 in design, dimensions, and construction. Further, the second side sheet 132 is spaced apart from the first side sheet 130. In one example, the first and second side sheets 130, 132 are parallel to each other. The first and second side sheets 130, 132 extend perpendicularly with respect to the aperture plate 124, and are fixedly coupled to the aperture plate 124. The first and second side sheets 130, 132 include a first pivoting means 134 and a second pivoting means 136, respectively. The first and second pivoting means 134, 136 swingably couple the radiator guard assembly 114 with the main frame 102 at the respective pivot points P1, P2.
Each of the first and second side sheets 130, 132 include a first mounting structure 138 and a second mounting structure 140, respectively. The first mounting structure 138 is fixedly coupled to the first side sheet 130. The first mounting structure 138 removably couples the first side sheet 130 of the radiator guard assembly 114 with the first side rail 116 of the main frame 102. Further, the second mounting structure 140 is fixedly coupled to the second side sheet 132. The second mounting structure 140 removably couples the second side sheet 132 of the radiator guard assembly 114 with the second side rail 118 of the main frame 102.
As shown in the accompanying figures, the first and second mounting structures 138, 140 extend from lower portions 142, 144 of the respective first and second side sheets 130, 132. Each of the first and second mounting structures 138, 140 removably couple the first and second side sheets 130, 132 of the radiator guard assembly 114 with the main frame 102, via a double shear attachment.
The first mounting structure 138 is similar in design, dimension, and construction to the second mounting structure 140. For explanatory purposes, the first mounting structure 138 will now be explained in detail with reference to FIG. 5. However, it should be noted that the details of the first mounting structure 138 provided below are equally applicable to the second mounting structure 140, without limiting the scope of the present disclosure.
Referring to FIG. 5, a perspective view of the first mounting structure 138 is shown. The first mounting structure 138 includes a base member 150. The base member 150 is coupled to the first side sheet 130 of the radiator guard assembly 114. More particularly, a top surface 152 of the base member 150 contacts with a bottom surface 154 (shown in FIG. 4) defined on the first side sheet 130. In one example, the base member 150 is coupled to the first side sheet 130 by welding, without any limitations.
The first mounting structure 138 is fork shaped. Accordingly, a first plate 158 extends from a first surface 162. Further, a second plate 160 extends from a second surface (not shown) of the base member 150. The second surface is defined opposite to the first surface 162. Further, the first and second plates 158, 160 are parallel to each other, and extend angularly from the base member 150. The first plate 158 is similar in design and dimensions to the second plate 160.
A lower end of each of the first and second plates 158, 160 is semi-circular in shape. The first plate 158 defines a first aperture 166. Further, the second plate 160 defines a second aperture 168 that is co-axial with the first aperture 166. The first and second apertures 166, 168 are defined proximate to the lower end of the respective first and second plates 158, 160. For coupling the radiator guard assembly 114 with the main frame 102, the first and second apertures 166, 168 are aligned with an aperture 170 (shown in FIG. 2) defined in the first side rail 116 for receiving a mechanical fastener 172 (shown in FIG. 3). The mechanical fastener 172 couples the first mounting structure 138 of the radiator guard assembly 114 with the first side rail 116 of the main frame 102, via a double shear attachment.
In the illustrated example, the mechanical fastener 172 is embodied as a steel pin. Alternatively, the mechanical fastener 172 may embody any other type of pin or bolt, without any limitations. It should be noted that the apertures 166, 168, 170 are embodied as through-holes. Further, for servicing or replacement of the radiator, the mechanical fasteners 172 may be removed so that the radiator guard assembly 114 may swing about the pivot points P2, P2 to provide access to the radiator.
In the illustrated example, the first mounting structure 138 is embodied as a unitary component. Alternatively, components of the first mounting structure 138, such as the base member 150, the first plate 158, and the second plate 160 may be manufactured as separate components that are later assembled to form the first mounting structure 138. In one example, the first mounting structure 138 is manufactured by a casting process. In other examples, the first mounting structure 138 may be manufactured using any additive manufacturing process, such as 3D printing, or any subtractive manufacturing process, such as machining, without any limitations.
Further, the first mounting structure 138 is made of a material that exhibits high strength and does not deform during operation of the machine 100. In one example, the first mounting structure 138 is made of a metal, such as cast steel. Alternatively, the first mounting structure 138 may be made of any other metal based on application requirements, without any limitations

INDUSTRIAL APPLICABILITY

The present disclosure relates to the radiator guard assembly 114 associated with the machine 100. The radiator guard assembly 114 is simple in design and manufacturing, cost effective, and easy to couple with the main frame 102.
The mounting structures 138, 140 of the radiator guard assembly 114 provide a double shear pin connection to the main frame 102. This type of connection reduces likelihood of pin/fastener deformation during machine operation. Also, the double shear pin connection makes removal of the pin/fastener easier for servicing and replacement. Further, due to the design of the mounting structures 138, 140, the first and second side sheets 130, 132 rest directly above the respective side rails 116, 118 of the main frame 102, thereby providing more clearance between the main frame 102 and the undercarriage system 106.
