[0026] In related technologies, a track type compact loader usually needs to install a track with a larger width when working to ensure the stability of the loader when moving, for example, to prevent side overturning and the like. However, when installing a wide track, the track gauge of the loader usually needs to be increased, which in turn easily causes an increase in the transverse space occupied by the loader, which is not conducive to the compactness and miniaturization of the loader.

[0027] Based on the above technical problem, the first aspect of the present utility model provides a vehicle frame assembly, referring to Figures 1 to 6 The vehicle frame assembly includes a vehicle frame main body 1 and a track frame 2. The vehicle frame main body 1 includes a bottom plate 110 and side plates 120 connected to opposite sides of the bottom plate 110. The bottom plate 110 and the two side plates 120 together enclose an accommodating cavity 130. The side plates 120 include main wall parts 121 and inwardly-retracted parts 122. In the width direction of the vehicle frame assembly, the distance between the two inwardly-retracted parts 122 is less than the distance between the two main wall parts 121. The main wall part 121 is provided with a through hole 1211 that communicates with the accommodating cavity 130. The vehicle frame main body 1 further includes support members 140 located in the accommodating cavity 130 and connected to the side plates 120. The support members 140 are used to suspend an engine. The number of track frames 2 is two, and each is connected to an inwardly-retracted part 122. In the height direction of the vehicle frame assembly, the main wall part 121 at least partially shields the track frame 2.

[0028] By the above-mentioned manner, that is, the vehicle frame assembly provided by the utility model, when the vehicle frame assembly is applied to the compact track loader, the engine of the loader can be installed in the accommodating cavity 130 between the bottom plate 110 and the side plate 120 and supported by the support 140, so as to reduce the compression of the bottom plate caused by the direct contact of the engine with the bottom plate, the output shaft of the engine can be transmitted to the working pump located in the accommodating cavity, the traveling motor can be connected to the working pump and arranged through the through hole 1211 and connected with the external track transmission, the high-pressure oil pumped by the working pump can drive the traveling motor to rotate, when it is required to use wide tracks to increase the stability of the moving operation of the loader, the vehicle frame assembly can directly replace the wide tracks without changing the track gauge (that is, without changing the specific structure of the track frame 2), without increasing the distance of the vehicle in the width direction, thereby reducing the transverse occupation space of the loader, the loader is more compact, and the passability in the narrow space is better.

[0029] It should be noted that, when the track frame 2 is connected to the inwardly-retracted portion 122, the inwardly-retracted portion 122 and the main wall portion 121 can jointly form an avoiding space 123, so that, when observing from top to bottom in the height direction of the vehicle frame assembly, the track frame 2 can be at least partially located in the avoiding space 123, in this arrangement, the distance between the two track frames 2 can be reduced without changing the structure of the track frame 2, directly replacing the wide tracks, and improving the compactness and miniaturization of the loader. Figure 1

[0030] In addition, in the above-mentioned embodiments, the inwardly-retracted portion 122 of the side plate 120 can also be attached to the engine on the side facing the accommodating cavity 130, thereby compressing the space of the accommodating cavity 130 to reduce the transverse occupation space of the vehicle frame assembly.

[0031] In some embodiments, as shown in Figure 1 and Figure 2 , the main wall portion 121 and the inwardly-retracted portion 122 are parallel in the extension direction, and the side plate 120 further comprises a transition portion 124 connected between the main wall portion 121 and the inwardly-retracted portion 122.

[0032] By the above-mentioned manner, the transition portion 124 can serve to connect the main wall portion 121 and the inwardly-retracted portion 122, and can also improve the overall structural strength of the side plate 120, for example, the transition portion 124 can be a connecting plate body having two ends connected to the main wall portion 121 and the inwardly-retracted portion 122 respectively, and the transition portion 124, the inwardly-retracted portion 122 and the main wall portion 121 can jointly enclose the avoiding space 123 in the above-mentioned embodiments, so that, when the track frame 2 is connected to the inwardly-retracted portion 122, the traveling motor installed on the track frame 2 can be stably arranged in the avoiding space 123 when connected to the working pump arranged through the through hole 1211. ​

[0033] Further, referring to Figure 1 and Figure 2 , the extending direction of the transition portion 124 is perpendicular to the main wall portion 121 and the inwardly recessed portion 122.

[0034] In this way, the transition portion 124 is perpendicular to the main wall portion 121 and the inwardly recessed portion 122, which can further improve the structural strength of the connection between the transition portion 124 and the main wall portion 121 and the inwardly recessed portion 122, i.e. the transition portion 124 can act as a reinforcing rib, further preventing the occurrence of bending deformation between the main wall portion 121 and the inwardly recessed portion 122, and the transition portion 124 is perpendicular to the main wall portion 121 and the inwardly recessed portion 122, i.e. the extending direction of the transition portion 124 is also parallel to the extending direction of the track, as shown in Figure 1 , when the track is mounted on the track frame 2, the track will form a triangular structure under the support of the track frame 2 and the travel motor, and as shown in Figure 1 , the extending direction of the transition portion 124 allows the avoidance space 123 to also form a triangular cavity structure that matches the track, thereby improving the compactness of the frame assembly and the track.

[0035] In some embodiments, referring to Figures 1 to 6 , the support 140 is arranged at least one on each side plate 120.

[0036] In this way, when the engine of the loader is arranged in the accommodation cavity 130, the engine bottom can be supported by the support 140, and the engine does not directly contact the bottom plate 110, and the four supports 140 can evenly distribute the engine weight, effectively reducing local stress concentration, thereby improving the overall life of the frame body 1, and by arranging at least one support 140 on each side plate 120, the stable support effect on the engine can be improved.

[0037] Further, by arranging the engine in the above-mentioned manner, the space formed between the engine and the bottom plate 110 can make the pipeline layout more reasonable in the space, without having to be arranged in a roundabout way, thereby further reducing the manufacturing cost of the loader.

[0038] Further, in order to further improve the stable support of the engine, referring to Figures 1 to 6 , the number of supports 140 is four and two are arranged at intervals on each side plate 120.

[0039] In this way, the four supporting pieces 140 can simultaneously support the four positions of the engine bottom, which can further improve the effect of stabilizing the engine. The specific arrangement height of the supporting pieces 140 and the positions connected to the side plates 120 can be adjusted according to the actual structure of the engine. The arrangement height of the supporting pieces 140 on the side plates 120 can be the same or different, and the appropriate arrangement can be selected according to the actual situation.

[0040] In the embodiment, as shown in Figures 1 to 6 the heights of the at least two supporting pieces 140 are the same in the height direction of the frame assembly.

[0041] In the above arrangement, the heights of the at least two supporting pieces 140 are the same, which can ensure that at least two supporting pieces 140 are at the same height when supporting the engine, thereby reducing or preventing the engine from tilting. In addition, two supporting pieces 140 at the same height can be arranged on two side plates 120 respectively, thereby achieving balanced support of the engine in the width direction of the frame assembly.

[0042] Alternatively, in a further embodiment, the four supporting pieces 140 can also have the same height in the height direction, which can also achieve stable support of the engine.

[0043] In order to improve the stability of the supporting piece 140 when supporting the engine, as shown in Figures 1 to 6 the supporting piece 140 includes a connecting portion 141 and a supporting portion 142. The connecting portion 141 is attached to the inner side wall of the side plate 120, and the supporting portion 142 is bent relative to the connecting portion 141 and has a supporting surface 1421.

[0044] In the above manner, when the supporting piece 140 supports the bottom surface of the engine, the supporting surface 1421 of the surface of the supporting portion 142 can be attached to the bottom of the engine, and the connecting portion 141 can be attached to the inner side wall of the side plate 120 to achieve the connection between the supporting piece 140 and the side plate 120. The specific connection between the connecting portion 141 and the side plate 120 can be any suitable connection, for example, a screw can pass through the side plate 120 and be screwed to the connecting portion 141 to tightly attach the connecting portion 141 to the side plate 120, or the connecting portion 141 can be directly connected to the side plate 120 by welding. The present embodiment does not make specific limitations.

[0045] In some embodiments, as shown in Figures 1 to 6 the supporting piece 140 further includes a reinforcing portion 143. The reinforcing portion 143 is connected to the supporting portion 142 and the inner side wall of the side plate 120, or the reinforcing portion 143 is connected to the supporting portion 142 and the connecting portion 141.

[0046] In this way, the reinforcing portion 143 can improve the structural strength of the support member 140 itself, that is, the reinforcing portion 143 mainly plays a role of a reinforcing rib in the support member 140, so as to prevent the support portion 142 from being bent relative to the connecting portion 141 or relative to the side plate 120, and improve the deformation resistance of the support portion 142 itself.

[0047] The second aspect of the utility model provides a kind of engineering machinery, which includes the frame assembly mentioned in the above specific embodiment, and has all beneficial effects in the above embodiment, wherein the engineering machinery can be loader applied the frame assembly, or, other engineering machinery with installation track requirement, such as excavator, crane, road roller or dump truck etc.

[0048] Although the embodiments of the utility model are described in conjunction with the drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the utility model, and such modifications and variations all fall within the scope of the utility model claimed.
