CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[001] The present application does not claim priority from any patent application.
TECHNICAL FIELD
[002] The present disclosure in general relates to the field of assembly of a power
train. More particularly, the present invention relates to a system for assembly of a power train in a truck.
BACKGROUND
[003] Currently, during mounting a power train (i.e. Engine, Radiator and Alternator
assembly] in an electric dump truck equipment, the power train is separately mounted on a sub frame structure of the electric dump truck equipment for easy removal from a main frame for maintenance. Further, one or more temporary brackets are used to lift the power train along with the sub frame structure and two or more temporary roller structure will be fitted. The power train mounted sub frame will be lifted above from bumper of the main frame around 180mm approximately to rotate the roller structure 180 degrees for the power train to rolls over the one or more temporary brackets and the power train is mounted over a mainframe of the electric dump truck equipment. Once the power train along with sub frame is mounted over the mainframe, the temporary brackets and the temporary roller structure need to be detached. Thus, in order to mount the power train, users have to take precautions during lifting and rolling the power train. Further, it is to be understood that the mounting of the power train is not assembly friendly. Also, the mounting of the power train requires more manpower for lifting and rolling operation. Thus, the process of mounting the power train consumes lot of time.

Furthermore, the power train may be mounted on the sub frame structure. In one embodiment, during operation the wheel may roll over the guiding edge. Based on the rolling operation of the wheel, the assembly or disassembly of the power train may be enabled.
[0013] Referring now to Figure 1, a system 100 for assembly of a power train 112 in
a truck is disclosed. In one embodiment, the present subject matter is explained considering the system 100 implemented as within the truck. It may be understood that the system 100 may be implemented in any type of truck, such as an electric dump truck, a mechanical dump truck, on-road truck, other mining equipment and the like.
[0014] In one embodiment, the system may comprise a frame structure 102. The
frame structure 102 may be mounted on a chassis of the truck. The frame structure 102 may be a main load bearing structure of the truck. In other words, the frame structure 102 may bear load of all components used for driving the truck, and the other components required for mounting. Further, the frame structure 102 may comprise a guide bracket

108. The guide bracket 108 may be made up of a metal. The guide bracket 108 may comprise a guiding edge. In one aspect, the guide bracket 108 may be mounted on the frame structure 102 in such a way that the guiding edge may make a defined angle with the frame structure 102. In one example, the guiding edge may not be parallel to the frame structure 102. The guiding edge may further comprise a restrict arm on both ends.
[0015] Further, the system 100 may comprise a sub frame structure 104. The sub
frame structure 104 may be mounted on the frame structure 102. In one example, size of the sub frame structure 104 may be less than size of the frame structure 102. The sub frame structure 104 may be a separate structure mounted on the frame structure 104 to carry components such as the power train, a suspension and the like.

train 112 may be mounted on the sub frame structure 104. The power train 112 may be an assembly of a radiator, an engine and an alternator. The power train 112 may be configured to drive the truck.
[0018] In one embodiment, during assembly or disassemble operation of the power
train 112, the wheel of the roller assembly 110 may roll over the guiding edge of the guide bracket 108. In one aspect, the rolling operation of the wheel over the guiding edge may be restricted by the restrict arm of the guiding edge. The wheel may roll in a forward direction or a backward direction. Based on the rolling operation of the wheel, the power train 112 may be moved in or out. In one example, rolling operation of the wheel towards outer end of the sub frame structure 104 may enable disassemble operation of the power train 112. In other example, rolling operation of the wheel towards inner end of the sub frame structure 104 may enable assembly operation of the power train 112. The power train 112 may be assembled or disassembled based on the rolling operation of the wheel.

[0019] Referring now to figure 2, an architecture 200 of a roller assembly 110
mounted on a sub frame structure 104 is illustrated in accordance with an embodiment of the present subject matter. In one embodiment, the roller assembly 110 may comprise a support structure 202 and a wheel 204.
[0020] In one embodiment, the support structure 202 may be mounted on the sub
frame structure 104. The support structure 202 may be an L-shaped structure. In the embodiment, one end of the L-shaped structure may be fixed to the sub frame structure 104. Further, other end of the L-shaped structure may be coupled to the wheel 204. In one aspect, the wheel 204 may be coupled to the support structure 202 through a hole using a tube and a bolt. Further, the wheel 204 may be engaged over a sliding edge of a guide bracket 108. In one embodiment, the wheel 204 may be a hardened wheel. The wheel 204 may be hardened at hardness 180 to 210 BHN (Brinell Hardness Number) at normalized condition. Further, the wheel 204 may be oil quenched at 820 to 850 degree Celsius before machining. Hardness of the wheel may be 248 to 293 BHN (Brinell Hardness Number) after machining.
[0021] Referring now to figure 3A and figure 3B, an architecture 300 of a guide
bracket 108 mounted on a frame structure 102 is illustrated in accordance with an embodiment of the present subject matter. In one embodiment, the guide bracket 108 may be mounted on the frame structure 102 using a nut and a bolt arrangement. The guide bracket 108 may comprise a guiding edge 304. The guiding edge 304 may make a definite angle with the frame structure 102. In one embodiment, the guiding bracket 108 may be mounted on the frame structure 102 in such a way that the guiding edge 304 makes the definite angle with the frame structure 102. In other words, the guiding edge 304 may not be parallel to the frame structure 202.
[0022] Further, the guiding edge 304 may comprise a restrict arm 302, 306 on both
ends. In one aspect, the restrict arm 302 at one end of the guiding edge 304 may be used to mount the guide bracket 108 on the frame structure 102. Further, the restrict arm 306 at other end of the guiding edge 304 may be floating. Further, a wheel of a roller assembly 110 may be engaged over the guiding edge 304. In one embodiment, during assembly or disassembly operation of the power train 112, the wheel may roll over the guiding edge 304. The restrict arms 304, 306 may be configured to restrict the rolling operation of the

wheel over the guiding edge 304. In other words, the wheel rolls over the guiding edge 304 from the restrict arm 302 to the restrict arm 306.
