Description
Technical field
The utility model relates to technical field of engineering machinery, relates in particular to minitype wheeled engineering machinery body frame structure for automotive.
Background technology
Along with China's rapid economy development, the quickening of town and country construction, the expansion of industrial wheeled equipment and use increasingly extensive, especially minitype wheeled engineering machinery, as small sized loader, small-sized excavator, with its easy making simple in structure, very the green grass or young crops in market narrows.Yet its technical shortcoming is not covered in holding of market, and is low as the rigidity of front frame, for impact, reverse, the holding capacity of moment of flexure is poor, the life-span short; Problems such as the complete machine turning radius is big, trafficability characteristic is poor, and is stable, that degree of flexibility is low, the existence of these problems warns people imperative to the improvement of traditional vehicle shelf structure.
Summary of the invention
At the shortcoming of prior art, the rigidity that the utility model proposes front frame is big, intensity good, the life-span is long, turning radius is little, trafficability characteristic is strong, stable industrial wheeled equipment vehicle frame flexibly.
The utility model adopts following technical scheme to realize: frame structure for wheel type engineering machine, comprise front frame, back vehicle frame, front driving axle, rear driving axle, it is characterized in that: described front frame is a body structure, it is to be welded by upper beam, underbeam, front panel, rear board, two flank casees, oil cylinder seat is arranged at the upper beam interposition, the both wings case is arranged at the upper beam two ends respectively, and box body cradle is arranged at the below of rear board, and the bridge installing plate is arranged at the two ends of underbeam; Front frame is connected by rotary pair with the back vehicle frame, before and after this rotary pair is arranged in the wheelbase of drive axle in the heart, it is to be made of last hinge and following hinge.
The described hinge of going up is by the articulated slab of stretching after jointed shaft and the front frame, afterwards the articulated slab that protracts of vehicle frame is connected, and oscillating bearing is arranged between articulated slab and the jointed shaft; Its upper end of described jointed shaft is connected with positioning support on being arranged at articulated slab by location-plate; Its lower surface is provided with by bolton and is close to the cover plate of articulated slab soffit.
Described down hinge is connected by the articulated slab of stretching after jointed shaft and the front frame, with articulated slab that back vehicle frame protracts and forms, oscillating bearing is arranged between articulated slab and the jointed shaft, and the upper end of jointed shaft is connected with positioning support on being arranged at articulated slab by location-plate.
Described front frame by bolton on front driving axle; The centre of back vehicle frame is connected to subframe by bearing pin, and this subframe is fastenedly connected by bolt and rear driving axle.
Advantage compared with prior art of the present utility model is: because front frame adopts body structure, strength and stiffness all improve a lot, for reverse, impact, the ability to bear of active force such as bending greatly strengthens, be much improved its application life.Since adopt rotary pair connect before and after vehicle frame, and before and after being arranged in drive axle wheelbase in the heart, cause the turning radius of car load little, improve the trafficability characteristic of car load; The employing of oscillating bearing has strengthened the stability of car load high speed driving; On the layout of front and back drive axle, the employing propons is fixed, the swing of back axle center, and this has just reduced the car load height, reduces the pivot angle of inter-axle shaft on rugged and rough road surface, the application life that can improve driving parts.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
See Fig. 1, frame structure for wheel type engineering machine, comprise front frame 4, back vehicle frame 5, front driving axle 2, rear driving axle 3, front frame 4 is a body structure, sees Fig. 2, Fig. 3, and it is to be welded by upper beam 44, underbeam 45, front panel 43, rear board 48, two flank casees 47, oil cylinder seat 42 is arranged at 44 interpositions of putting the beams in place, both wings case 41 is arranged at 44 two ends of putting the beams in place respectively, and box body cradle 18 is arranged at the below of rear board 48, and bridge installing plate 46 is arranged at the two ends of underbeam 45.Its comprehensive mechanical performance of case structure is much improved, and has prolonged its application life.See Fig. 1, front frame 4 is connected by rotary pair with back vehicle frame 5, before and after this rotary pair is arranged in the wheelbase of drive axle in the heart, the setting of this position can make that turning radius reduces, trafficability characteristic improves.This rotary pair is to be made of last hinge 6 and following hinge 7.Upper and lower two hinges link into an integrated entity the front and back vehicle frame, offset the moment of flexure of vehicle frame at the hinge place with horizontal force between two hinges and the product of opening grade size.See Fig. 4, the described hinge 6 of going up is by the articulated slab of stretching after jointed shaft 8 and the front frame 19, afterwards the articulated slab 22 that protracts of vehicle frame is connected, and oscillating bearing 9 is arranged between articulated slab 22 and the jointed shaft 8; Described jointed shaft 8 its upper ends are connected with positioning support 11 on being arranged at articulated slab by location-plate 10.Its lower surface is provided with fastening and be close to the cover plate 12 of articulated slab 19 soffits by bolt 17, and hinge 6 has two degree of freedom on this.See Fig. 5, the articulated slab 23 that described down hinge 7 protracts by the articulated slab of stretching after jointed shaft 24 and the front frame 4 20, articulated slab 21, by back vehicle frame 5 is connected and forms, oscillating bearing 9 is arranged between articulated slab 23 and the jointed shaft 24, and the upper end of jointed shaft is connected with positioning support 11 on being arranged at articulated slab by location-plate 25.This time hinge 7 has one degree of freedom.The use of oscillating bearing can strengthen the stationarity of car load high-speed cruising, and can significantly reduce the wear intensity of vehicle frame hinge hole.See Fig. 1, front frame 4 is anchored on the front driving axle 2 by bolt 16; The centre of back vehicle frame 5 is connected to subframe 14 by bearing pin 13, and subframe 14 is fastenedly connected by bolt 15 and rear driving axle 3.This subframe 14 is a frame construction, and this kind set-up mode can reduce the car load height of C.G., reduces the pivot angle of inter-axle shaft on rugged and rough road surface, improves the life-span of driving parts.
