Problems solved by technology

However, the acceptance of the market does not conceal its technical shortcomings, such as low rigidity of the front frame, poor resistance to impact, torsion, and bending moment, and short life; the whole machine has a large turning radius, poor passability, stability, and flexibility. The existence of these problems warns people that it is imperative to improve the traditional frame structure

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] See Fig. 1, the frame structure of wheeled engineering machinery, including front frame 4, rear frame 5, front drive axle 2, rear drive axle 3, front frame 4 is a box structure, see Fig. 2, Fig. 3, it It is welded by the upper beam 44, the lower beam 45, the front panel 43, the rear panel 48, and the wing boxes 47 on both sides. The hinged frame 18 is arranged below the rear panel 48 , and the bridge mounting plate 46 is arranged at both ends of the lower beam 45 . The comprehensive mechanical properties of the box structure are greatly improved, prolonging its service life. As shown in Fig. 1, the front frame 4 and the rear frame 5 are connected by a slewing pair, which is located at the center of the wheelbase of the front and rear drive axles. The setting of this position can reduce the turning radius and improve the passability. This rotary pair is made ...

Abstract

The invention relates to a structure of wheel projective mechanical frame, wherein said frame comprises: a front frame and a back frame; said front frame is a box, formed by upper beam, lower beam, front panel, back panel, and two side wing plates; the cylinder base in at the middle of upper beam; two wing boxes are at two ends of upper beam; the box hinge support is under the back panel; the bridge mounting plates are at two ends of lower beam; the front and back frames are connected via rotational couple; said rotational couple is at the axial center of front and back driving bridges; the front bridge is fixed, and the back bridge swings. The invention can be used in small wheel mechanical machine, with long service life, high support ability, flexible operation and high stability.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a frame structure of a small wheeled engineering machinery. Background technique [0002] With the rapid development of my country's economy and the acceleration of urban and rural construction, the expansion and application of wheeled construction machinery has become increasingly widespread, especially small wheeled construction machinery, such as small loaders and small excavators, are simple and easy to manufacture due to their simple structure. Get the love of the market. However, the acceptance of the market does not conceal its technical shortcomings, such as low rigidity of the front frame, poor resistance to impact, torsion, and bending moment, and short life; the whole machine has a large turning radius, poor passability, stability, and flexibility. The existence of these problems warns people that it is imperative to improve the...
