FRAME FOR CONSTRUCTION MACHINE

Abstract

A frame for a construction machine includes a pair of side truss members extending along a longitudinal axis of the construction machine. Each side truss member defines one or more first cut-outs, an axle opening for receiving a portion of an axle assembly of the construction machine, and a first through-aperture. The first through-aperture is adapted to at least partially receive a fastening element for coupling the axle assembly with a corresponding side truss member. The frame also includes a first lateral truss member extending between the pair of side truss members and defining at least one second cut-out. The frame further includes a second lateral truss member extending between the pair of side truss members and defining at least one third cut-out. The pair of side truss members, the first lateral truss member, and the second lateral truss member together define a hollow space of the frame.

Description

TECHNICAL FIELD

The present disclosure relates to a construction machine, and more particularly, to a frame for the construction machine.

BACKGROUND

A construction machine, such as a motor grader, may be used in road construction and maintenance for displacing, distributing, and leveling material, such as, soil, gravel, snow, and the like. The construction machine includes a frame assembly that may support various components of the construction machine including, but not limited to, a power source, an operator cab, wheels, and the like. The frame assembly may include a front frame and a rear frame pivotally coupled to each other.

Conventionally, the rear frame may include a number of heavy rails coupled to each other to form a structure of the rear frame. Further, the rear frame of the construction machine may include a mounting structure for coupling a work implement, such as, a ripper assembly therewith. The mounting structure may include a pair of brackets that may be coupled with the rails of the conventional rear frame.

The rear frame may also include a pair of elongated tag links extending forwardly from the mounting structure. The tag links may allow coupling of a rear axle of the construction machine with the rear frame. The tag links and the mounting structure are embodied as separate components that may be coupled with the rails of the rear frame using joining processes, such as, welding. The tag links and the mounting structure increase part numbers associated with the rear frame. Further, the tag links and the mounting structure may be heavy, and may increase an overall cost and weight associated with the rear frame.

U.S. Pat. No. 9,267,268 describes a motor grader includes a fuel tank, a vehicle body frame, a left-side mount part, a right-side mount part, a rear-side mount part and a reducing agent tank. The left-side mount part and the right-side mount part are respectively disposed on a left lateral frame and a right lateral frame while being disposed on both sides of the fuel tank in a vehicle width direction, and fix the fuel tank to the vehicle body frame. The rear-side mount part is disposed on the left lateral frame in the vehicle width direction while being disposed rearward of the fuel tank and fixes the fuel tank to the vehicle body frame. The reducing agent tank is disposed rearward of and adjacently to the fuel tank while being disposed on the right lateral frame side and accumulates a reducing agent for processing an exhaust gas from an engine.

INDUSTRIAL APPLICABILITY

The frame 106 of the present disclosure includes a simple, truss-based design. Further, the frame 106 has a robust structure that may provide uniform distribution of loads across the frame 106, during operation of the construction machine 100. The frame 106 includes the multiple cut-outs 154, 156, 158, 160, 184, 186, 188, 190, 204, 206, 230 that may reduce a weight of the frame 106 as well as a material used to manufacture the frame 106. Further, the frame 106 includes an integrated structure defining the first and second through-apertures 164, 194 that receive the fastening elements 165, 195, respectively, for coupling the axle assembly 118 with the frame 106. Thus, the frame 106 eliminates conventional floating tag links that couple the axle assembly 118 with the frame 106.

Further, the second lateral truss member 224 includes the mounting plates 232, 234, 236, 238 for coupling the work implement 124 of the construction machine 100 with the frame 106. Thus, the frame 106 may eliminate the conventional implement mounting structures that couple the work implement 124 with the frame 106. Thus, the first side truss member 134, the second side truss member 136, and the second lateral truss member 224 described herein may combine the functionality of the conventional tag links and the implement mounting structures. Hence, the frame 106 may reduce part numbers associated with the construction machine 100. Further, a design of the pair of side truss members 134, 136 may provide improved strength to a portion of the frame 106 that couples with the axle assembly 118. Moreover, the first and second side truss members 134, 136 may provide a cost-effective, easy, and quick technique for mounting the panels 252 with the frame 106.

While aspects of the present disclosure have been particularly shown and described with reference to the embodiments above, it will be understood by those skilled in the art that various additional embodiments may be contemplated by the modification of the disclosed machines, systems and methods without departing from the spirit and scope of the disclosure. Such embodiments should be understood to fall within the scope of the present disclosure as determined based upon the claims and any equivalents thereof.
