Abstract
The utility model discloses a frame behind loader with shock attenuation effect, including articulated seat, well roof beam structure, tailboard, left side roof beam and right side roof beam, back frame of a box is constituteed to articulated seat, tailboard, left side roof beam, right side roof beam, articulated seat in the front portion of back frame, well roof beam structure is located the middle part of back frame, and the tailboard is located the afterbody of back frame, left side roof beam and right side roof beam are the veneer structure, and rounding off connection and rounding off face below are equipped with the reinforcing plate between articulated seat and left side roof beam, the right side roof beam, and the inboard intermediate position of left side roof beam and right side roof beam is equipped with board -like supporting beam, and back frame rear portion is equipped with the installing support, and the installing support is located the inboard of left side roof beam, right side roof beam respectively, the tailboard inboard is equipped with the fixed bolster. This neotype beneficial effect does: strengthened the intensity of back frame vulnerabilities on the one hand, and then improved the life -span of whole back frame, frame and veneer structure girder behind the boxed structure, the high and save raw materials of structural strength, on the other hand is when crooked vibrations take place for the rounding off face, and this intensity of locating can be strengthened to inboard reinforcing plate to to do all can and conduct other positions, reduce complete machine vibrations and then noise reduction.
Description
Technical field
The utility model relates to a kind of Rear frame of engineering machinery, particularly relates to a kind of Rear frame of loader with damping effect.
Background technology
Rear frame of loader is stressed parts the most complicated in each structural member of loader, and it will bear from the different load of the parts such as front frame, counterweight, motor, two change assembly, driver's cabin and rear driving axle.Act on while many times Rear frame will bear the load such as tension and compression and bending, its stress condition very severe.Especially the connection welding place of hinged seat and crossbeam, especially a stress concentration point, be easy to be subject to vehicle body vibrations and cause fracture, therefore need to strengthen intensity herein and damping effect.
Summary of the invention
The purpose of this utility model to provide a kind of Rear frame of loader with damping effect.
For achieving the above object, the utility model is implemented according to following technical scheme: a kind of Rear frame of loader with damping effect, comprise hinged seat, middle beam frame, tailgate, left side beam and right side beam, described hinged seat, tailgate, left side beam, right side beam form the Rear frame framework of a box, described hinged seat is positioned at the front portion of Rear frame framework, described middle beam frame is positioned at the middle part of Rear frame framework, and described tailgate is positioned at the afterbody of Rear frame framework; Described left side beam and right side beam are single plate structure, between described hinged seat and crossbeam, rounding off connects and is provided with stiffener below rounding off face, inside described left side beam and right side beam, centre position is provided with board-like brace summer, described Rear frame frame rear portion is provided with mounting bracket, and described mounting bracket lays respectively at the inner side of left side beam, right side beam; Fixed support is provided with inside described tailgate.
Further, triangle reinforcing rib is provided with between described fixed support and tailgate.
Compared with prior art, the beneficial effects of the utility model are: the intensity enhancing Rear frame tender spots on the one hand, and then improve the life-span of whole Rear frame, case structure Rear frame and single plate structure crossbeam, high and the conservation of structural strength, on the other hand when rounding off face bends vibrations, the stiffener of inner side can strengthen the intensity at this place, and power is transmitted to other positions, reduce complete machine vibrations and then reduce noise.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is A-A structural representation of the present utility model.
Detailed description of the invention
