Description
Technical field
The invention belongs to construction machinery and equipment, is the middle-size and small-size wheel type loader in construction machinery and equipment furtherly, is Specifically frame strand connecting device before and after a kind of small wheel-type loading machine.
Background technology
In now widely used middle-size and small-size wheel type loader, before and after it, frame is all the structure of copying large-scale wheel type loader, and connected by a jointed shaft, hydraulic-driven turns to, and Rear frame is installed on rear driving axle by rocking equipment.Such structure for large-scale wheel type loader due to sole mass and car load width larger, large problem can not be produced, but for small wheel-type loading machine, because sole mass is little, vehicle body is narrow, the height of gravitational center that such structure just causes car load is higher, and traveling and stability under working conditions can be severe.When some complex-terrain operations, the problems such as unstable generation rollover can be caused because center of gravity is high, there is very large accident potential.Once someone proposed new structure, in the hope of improving this problem, as the Chinese patent patent No.: 2012105627547, name is called: the application for a patent for invention of " novel loader front/rear frame articulated structure ", it is disclosed that the jointed shaft of an adapter shaft front end ball head structure connects forward and backward frame by tapered pin, the structure after the other end is fixed on, on forebay.Although being made moderate progress by performance of car load, processing and assembly precision require high, not easily adjust, once wearing and tearing, still there is the problem being hinged inefficacy, and the connection of axle head and frame is for being rigidly connected, also easy because of generation distortion fractures such as torsion, shearings.Still do not break away from because Rear frame is arranged on rocking equipment, the puzzlement of the higher problem of car load center of gravity yet.In order to overcome these problems, designer of the present invention has done and has studied in earnest, proposes goal of the invention of the present invention.
Summary of the invention
Goal of the invention of the present invention puts forward with not enough to overcome current defect.Namely frame strand connecting device before and after a kind of small wheel-type loading machine is provided.
Technical solution of the present invention realizes like this, frame strand connecting device before and after this small wheel-type loading machine, there is forebay (1) and afer bay (2), front vehicle frame has pin plate (3) in one group of front vehicle frame, Rear frame has pin plate (4) in one group of Rear frame, pin plate has pin-and-hole to front vehicle frame for pin plate and Rear frame, be respectively fitted with upper pin (5), it is characterized in that linking connecting rod (6) at the midway location of two upper pins by upper joint bearing (8) assembling; There is in the bottom of front vehicle frame a front vehicle frame lower bearing pin fixedly pull (12), hinged adapter plate (9) under the bottom of Rear frame has a Rear frame, front vehicle frame lower bearing pin adapter plate assembles lower bearing pin (11), the hypozygal bearing (10) on lower bearing pin (11) coordinates assemble with fixedly pull (12) hinged under Rear frame.
Useful technique effect of the present invention is: owing to have employed this device, Rear frame can directly be installed on above rear driving axle, the small wheel-type loading machine of same structure, after adopting this device, the center of gravity of Rear frame reduces more than at least 100 millimeters, and for small wheel-type loading machine, this has revolutionary innovation reform, this improves the stability of car load and the carrying capacity of complex site.And, owing to have employed the two panels pin plate combination of front vehicle frame and Rear frame, hinge joint is won in succession and is assemblied in the middle frame mode of two panels pin plate, ensure that hinge joint connecting rod has enough spaces to produce displacement with oscillating bearing when being subject to the External Force Acting of all directions from structure, thus offset the external force load brought thus, reach the object that balance car load is stable.When work-yard is uneven, opposing oscillatory centered by the following articulation joint bearing of front/rear frame.Rugged road surface is adapted to by front/rear frame opposing oscillatory.Whole vehicle stability can be superior, and can omit and wave support, reduces costs, improve reliability.And have employed oscillating bearing, its lubricity, adjusting function are all very superior, and reliability of service is protected.The stationary positioned device requirement on machining accuracy of oscillating bearing is low, assemble, adjust simple and convenient, have in using automatic aligning and gap adjustment make up function, safeguard simple and convenient.

Fig. 1 is link structure of the present invention assembling schematic diagram, and Fig. 2 is the cross sectional plan view in Fig. 1.Sequence number is in the accompanying drawings described as: 1, front vehicle frame, and 2, Rear frame, 3, pin plate in front vehicle frame, 4, pin plate in Rear frame, 5, upper pin, 6, articulated linkage, 7, bearing gland, 8, upper joint bearing, 9, hinged adapter plate under Rear frame, 10, hypozygal bearing, 11, lower bearing pin, 12, front vehicle frame lower bearing pin fixedly pulls, 13, line of centers, 14, pressing plate, 15, through hole, 16, fixed cover.
Detailed description of the invention
Below in conjunction with the embodiment provided in accompanying drawing, structure of the present invention and use are described in detail.With reference to accompanying drawing, frame strand connecting device before and after this kind of small wheel-type loading machine, there is forebay (1) and afer bay (2), front vehicle frame has pin plate (3) in one group of front vehicle frame, Rear frame has pin plate (4) in one group of Rear frame, pin plate has pin-and-hole to front vehicle frame for pin plate and Rear frame, be respectively fitted with upper pin (5), it is characterized in that linking connecting rod (6) at the midway location of two upper pins by upper joint bearing (8) assembling; There is in the bottom of front vehicle frame a front vehicle frame lower bearing pin fixedly pull (12), hinged adapter plate (9) under the bottom of Rear frame has a Rear frame, front vehicle frame lower bearing pin adapter plate assembles lower bearing pin (11), the hypozygal bearing (10) on lower bearing pin (11) coordinates assemble with fixedly pull (12) hinged under Rear frame.Oscillating bearing and the fixing of hinge joint connecting rod are located by bearing gland (7) and fix.
In order to improve described new construction small sized loader before and after the operating accuracy of frame connector and reliability, by special design, by the shaft centre line of the lower bearing pin (10) on the axis of the upper pin (5) on pin plate in said front vehicle frame and front vehicle frame lower bearing pin adapter plate (12) on same line of centers (13).Thus when ensureing that turning to, float and to wave etc. action occurs, the stability of car load reaches unanimity.Namely pass through the raising of manufacture and assembly precision, improve the stability of car load further.
In order to improve described new construction small sized loader before and after the rigidity of frame connector, in the Rear frame of said Rear frame (2), the end of pin plate (4) is closed by the orifice plate (14) with through hole (15), and articulated linkage (6) is passed through from the through hole (15) orifice plate.Thus ensureing no matter front/rear frame wigwag motion or to pitch or car load the distortion such as to rock when occurring, chain connective pole and the oscillating bearing coordinated with it have enough spaces to produce displacement with being out of shape.Thus achieve the traction of front/rear frame after the structure of this device adopts, stable direction is reliable, meanwhile, what produce when complex-terrain operation waves, also can stablize operation and traveling under the deformation condition such as torsion.
In order to ensure hypozygal bearing installation, debug simple and convenient, the oscillating bearing on the lower bearing pin (10) on the front vehicle frame lower bearing pin adapter plate (12) in said front vehicle frame is fixed by fixed cover (16) and lower bearing pin captive nut axial location.In like manner, upper joint bearing also can adopt the mounting structure identical with hypozygal bearing.
