BOLTED CHASSIS FRAME FOR A MACHINE

摘要

A chassis frame for a machine has a rail assembly with a first side plate with a first outer surface, a second side plate with a second outer surface, a base plate and roof plates, connectable with the first and second side plates. A connection assembly connects the first side plate, base plate, second side plate, and roof plates, and has a first bracket assembly and a second bracket assembly. The first bracket assembly and the second bracket assembly include first portions and second portions. First portions connect to the base plate and the roof plates. Threaded fasteners extend into the second side plate and the first side plate and are routed through the second portions. Further, a sleeve positioned about the threaded fasteners extend from the first outer surface to the second outer surface, forming an interface respectively between the threaded fastener and the first and second side plate.

主权项

1. A chassis frame for a machine, the chassis frame comprising:
a rail assembly including:
a first side plate with a first outer surface;a base plate angularly connectable with the first side plate;a second side plate with a second outer surface, the second side plate being angularly connectable to the base plate and being positioned relatively parallely and symmetrically oppositely to the first side plate, across the base plate;one or more roof plates angularly connectable with the second side plate and the first side plate, and imparting a substantially closed, box-shaped profile to the side rail assembly;a connection assembly facilitating connection between the first side plate, the base plate, the second side plate, and the one or more roof plates, the connection assembly including:
at least one first bracket assembly;at least one second bracket assembly, with each of the at least one first bracket assembly and the at least one second bracket assembly including first portions and second portions, wherein first portions of each of the at least one first bracket assembly and the at least one second bracket assembly connect to one of the base plate and the one or more roof plates; andat least a pair of threaded fasteners, with each threaded fastener among the at least a pair of threaded fasteners extending into the second side plate and being routed through the first side plate respectively through the second portions of each of the at least one first bracket assembly and the at least one second bracket assembly, with each threaded fastener including:
a sleeve positioned about each threaded fastener and extending from the first outer surface of the first side plate to the second outer surface of the second side plate, forming an interface respectively between each threaded fastener and the first side plate and the second side plate.
