Description

Bulldozer integrated form vehicle frame

Technical field:

The utility model relates to a kind of bulldozer basic components, especially a kind of bulldozer integrated form vehicle frame.

Background technology:

Vehicle frame is as the basic components of bulldozer, at present main the employing by the structure that is connected with parts such as crossbeam, bogie frame, wing plate, end backplate, preceding hoods respectively such as bolt, bearing pin, mainly there is following shortcoming: (1) complex structure, mechanical model is difficult to set up accurately, and force analysis is difficulty comparatively; (2) associated member is many, assembling, adjustment inconvenience, and connecting portion bolt, bearing pin etc. bear bigger alternation moment of flexure and moment of torsion, and intensity and rigidity are weak links, have potential safety hazard; (3) processing, welding are complicated, and manufacturing cost height, cycle are long; (4) as ROPS/FOPS driver's cabin or canopy are installed, need positions such as vehicle frame, wing plate are strengthened, the parts versatility is poor.

Summary of the invention:

The purpose of this utility model provides a kind of bulldozer integrated form vehicle frame, integrated functions such as traditional vehicle frame, crossbeam, bogie frame, wing plate, end backplate, cab legs are in one, solve original bulldozer body frame structure for automotive complexity, associated member is many, assembling, adjustment inconvenience, processing, welding are complicated, and manufacturing cost height, cycle are long, the defective of parts versatility difference.

The purpose of this utility model realizes as follows: it comprises main car frame, crossbeam, bogie frame, wing plate, end backplate, cab legs, main car frame, bogie frame, front beam, rear cross beam, wing plate, end backplate, cab legs are become one, the front portion of main car frame and postmedian have horizontal reinforcing rib as front beam and rear cross beam, the same side end welding bench vehicle frame of front beam and rear cross beam; There is a header board that connects mainframe the both sides, middle part of main car frame, the foundry goods connector of back plate, leave driver's cabin on this connector tie point is installed, lift cylinder is installed tie point, portal frame is installed tie point, make the structure at this place quite compact simple and direct, saved numerous parts, simplified the structure of vehicle frame greatly, has enough intensity and rigidity simultaneously, the one that is installed on that collects a plurality of parts, eliminated the problem that traditional structure disperses to install the excessive or easy interference of the fit clearance that often occurs, adjustment repeatedly when having reduced assembling, reduce labour intensity, improved the versatility of each parts, shortened the manufacturing cycle; Rear cross beam is the box-shaped reinforcing rib, and the position of this muscle and structure have guaranteed the intensity and the rigidity at machine rear portion, and provides necessary base for the choosing of parts such as rear haulage frame, ridge buster, winch dress; Mounting bracket behind the main car frame rear portion welding planer-type driver's cabin, the form of structure at this place has also played the effect as the back web beam of mainframe except the back installation fulcrum as driver's cabin; Rack construction behind the driver's cabin under the mounting bracket is that fuel tank installing plate, ridge buster installing plate and end stiffener Combination Welding become the triangle inner chamber body of a sealing, thereby makes the intensity at this place obtain sufficient reinforcement and reinforcement; Inner chamber body top is the fuel tank installation site, concentrate placement by traditional placed apart changing into, the installation site that makes fuel tank is forwarded to by original installation on the wing plate of the left and right sides and is directly installed on the vehicle frame, thereby vacateed more space for left and right sides wing plate and arrange the component that other is installed, simplified assemble flow, client's operation and management have been made things convenient for, because of there not being big installed part on the wing plate, so can simplify wing plate to a great extent; The inner chamber body back is the ridge buster installation site, and the triangle inner chamber body has guaranteed the intensity needs that fuel tank is installed and ridge buster is installed; Wheel limit running motor and hub reduction box body that main car frame rear lower both sides have the reinforcing rib with the main car frame postmedian to weld together, shared space is very little, and structure is also quite compact, has saved complicated rear axle box and final gearbox than traditional structure; Reinforcing rib is as rear haulage frame installation site; Both sides, main car frame top are welded with wing plate, and there is a bending gusset that connects plate behind wing plate, the mainframe, fuel tank installing plate, ridge buster installing plate and end stiffener at the main car frame rear portion, and this gusset has also played the effect of appearance and modeling except that as the reinforcing rib.

The utility model is compared the advantage that has with traditional vehicle frame: (1) integrated functions such as traditional vehicle frame, crossbeam, bogie frame, wing plate, end backplate, cab legs, be easy to set up the whole mechanical model of vehicle frame, utilize ANSYS software to carry out analysis-by-synthesis, more traditional soil-shifting locomotive frame has more rational strength and stiffness; (2) cancel installation between traditional soil-shifting locomotive frame, crossbeam, bogie frame, wing plate, end backplate, the cab legs, shortened assembly period, reduced junction, position potential faults; (3) compare with traditional vehicle frame, crossbeam, bogie frame, wing plate, end backplate, cab legs, reduced processing, welding tooling, shortened the manufacturing cycle, reduced manufacturing cost, be convenient to tissue production; Each parts of traditional structure all need have a cover processing, frock to guarantee, and the vehicle frame of this integrated form only needs a cover processing, welding tooling; (4) the anterior reasonable Arrangement that adopts veneer and reinforcing rib of vehicle frame, the anterior box typed structure of more traditional vehicle frame is simple, makes convenient; (5) integrate the installation of driver's cabin, lift cylinder, portal frame and the multiple functions such as connection of front and back vehicle frame, have higher intensity and rigidity, greatly simplify than traditional structure.
