Description
Technical field
The invention belongs to construction machinery product, is the middle-size and small-size wheel loader in engineering machinery furtherly, be exactly a kind of new construction loader before and after frame connector.
Background technology
For now widely used middle-size and small-size wheel loader, before and after it, frame is all the structure of copying large-scale wheel 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 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 C.G. that such structure just causes car load is higher, and traveling and stability under working conditions can be severe.When some complicated landform 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 a connecting axle front end ball head structure connects forward and backward frame by cone 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
The deficiency that goal of the invention of the present invention exists in order to the destabilizing factor overcoming above-mentioned existence puts forward.Frame connector before and after the loader that namely a kind of new construction be provided.
Technical solution of the present invention realizes like this, frame connector before and after the loader of this new construction, there is forebay (1) and afer bay (2), front frame has pin plate (3) in one group of front frame, Rear frame has pin plate (4) in one group of Rear frame, pin plate has pin-and-hole to front frame for pin plate and Rear frame, be respectively fitted with upper pin (5), it is characterized in that in the centre position of two upper pins by upper joint bearing (8) assembling hinge joint connecting rod (6); Pin plate (12) under the bottom of front frame has a front frame, pin plate (9) under the bottom of Rear frame has one group of Rear frame, under Rear frame, pin plate assembles lower bearing pin (11), the hypozygal bearing (10) on lower bearing pin (11) win in succession with front frame downside pin (12) coordinate and assemble.
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 handling capacity of complex site.And, owing to have employed the two panels pin plate combination of front 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 greasy property, adjusting function are all very superior, and dependability 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.
Accompanying drawing explanation
Accompanying drawing 1 is syndeton of the present invention assembling schematic diagram, and Fig. 2 is the cross sectional plan view in Fig. 1.Sequence number in accompanying drawing: 1, front frame, 2, Rear frame, 3, pin plate in front frame, 4, pin plate in Rear frame, 5, upper pin, 6, articulated linkage, 7, bearing gland, 8, upper joint bearing, 9, pin plate under Rear frame, 10, hypozygal bearing, 11, lower bearing pin, 12, hingedly under front frame to win in succession, 13, center line, 14, pressing plate, 15, through hole.
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 connector before and after the loader of this kind of new construction, there is forebay (1) and afer bay (2), front frame has pin plate (3) in one group of front frame, Rear frame has pin plate (4) in one group of Rear frame, pin plate has pin-and-hole to front frame for pin plate and Rear frame, be respectively fitted with upper pin (5), it is characterized in that in the centre position of two upper pins by upper joint bearing (8) assembling hinge joint connecting rod (6); Pin plate (12) under the bottom of front frame has a front frame, pin plate (9) under the bottom of Rear frame has one group of Rear frame, under Rear frame, pin plate assembles lower bearing pin (11), the hypozygal bearing (10) on lower bearing pin (11) win in succession with front frame downside pin (12) coordinate and assemble.Be no matter that group pin plate of front frame or Rear frame, be generally that two panels plate is combined into one group, it be processed with pin-and-hole, coordinate with bearing pin.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 loader before and after the operating accuracy of frame connector and reliability, by special design, the shaft centre line of the lower bearing pin (10) on pin plate (9) under the axis of the upper pin (5) on pin plate in said Rear frame and Rear frame is designed on same center line (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 loader before and after the rigidity of frame connector, in the front frame of said front frame (1), the end of pin plate (3) is closed by the orifice plate (14) with through hole (15), and closure to adopt the simplest welding connection structure.Articulated linkage (6) is passed through from the through hole (15) orifice plate, thus ensureing that no matter front/rear frame is vacillated now to the left, now to the right or to be pitched 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, what produce when complicated landform operation waves, also can stablize operation and traveling under the deformation condition such as torsion.
By the use of this apparatus structure, the reliability and stability brought to medium and small wheel loader have non-obvious positive effect, have greatly application value.
