The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present application and should not be construed as limiting the present application.

The track assembly of the embodiments of the present application is described below with reference to the drawings.

The crawler assembly provided by the embodiment of the application can be applied to light engineering machinery vehicles, such as a small harvester, a small weeding machine, a small excavator or a small conveying vehicle.

As shown in fig. 1, 2, 5, 6 and 7, the track assembly includes a plurality of track driving wheel sets 100, a track traveling frame 200, and a track 300, the plurality of track driving wheel sets 100 (e.g., 4 track driving wheel sets 100) being respectively provided on the track traveling frame 200, wherein,

the track driving wheel set 100 comprises a first beam 101, an adjusting assembly 102, a first driving device 103 and a second driving device 104, wherein the first beam 101 and the track walking frame 200 are movably connected.

An adjustment assembly 102 is hinged to one end of the first beam 101, wherein the adjustment assembly 102 is used to support the track 300.

One end of the first driving device 103 is hinged to the adjusting assembly 102, and the other end of the first driving device 103 is hinged to one end of the first beam 101 away from the adjusting assembly 102, wherein the first driving device 103 is used for driving the adjusting assembly 102 to move.

One end of the second driving device 104 is fixedly connected with the crawler belt walking frame 200, and the other end of the second driving device 104 is fixedly connected with the first beam 101, wherein the second driving device 104 is used for driving the first beam 101 to move linearly along the crawler belt walking frame 200.

It should be noted that, in the track assembly in the embodiment of the present application, the track driving wheel set 100 may be connected to a control system of a light construction machine vehicle, for example, the track driving wheel set 100 may be connected to a central control system of a small harvester, a small weed killer, a small excavator or a small transport vehicle.

The track assembly in the embodiment of the present application may include 4 track driving wheel sets 100, 1 track traveling frame 200, and 1 track 300,4 track driving wheel sets 100 for supporting the track 300 and moving the track 300.

Specifically, any 2 of the 4 crawler belt driving apparatuses 100 are symmetrically disposed at an upper portion of the crawler belt walking frame 200, and the remaining 2 of the 4 crawler belt driving apparatuses 100 are symmetrically disposed at a lower portion of the crawler belt walking frame 200, while 2 crawler belt driving apparatuses at the same side in the vertical direction are also symmetrically disposed.

When a user operates a small-sized harvester or a small-sized weeder equipped with the crawler assembly of the embodiment of the present application, if the ground to be driven is relatively flat and has relatively muddy texture, for example, in muddy paddy field or grassland, the user can control the upper 2 of the 4 crawler driving devices 100 to approach each other and the lower 2 of the 4 crawler driving devices 100 to separate from each other by operating the central control system of the small-sized harvester or the small-sized weeder, at this time, the crawler 300 has a regular trapezoid shape, and on one hand, the crawler 300 having the regular trapezoid shape has relatively low pressure on the ground, so that the harvester or the weeder can be prevented from being stuck in the muddy soil, and on the other hand, the crawler 300 having the regular trapezoid shape can make the harvester or the weeder more stable during driving, thereby ensuring more reliable operation of the harvester or the weeder.

When a user operates the mini excavator or the mini transportation truck equipped with the crawler assembly according to the embodiment of the present invention, if the driving ground is abrupt and hard, for example, on a large-scale damaged road surface or a bumpy ground surface with a semi-buried boulder, the user can operate the central control system of the mini excavator or the mini transportation truck to control 2 of the 4 crawler driving devices 100 located at the upper portion to be away from each other and 2 of the 4 crawler driving devices 100 located at the lower portion to be close to each other, at this time, the crawler 300 will be in the shape of an inverted trapezoid, and the crawler 300 in the shape of the inverted trapezoid has good climbing and passing capabilities, so that the mini excavator or the mini transportation truck can quickly pass through the pothole ground.

When a user operates a small-sized harvester, a small-sized weeder, a small-sized excavator or a small-sized conveyor vehicle equipped with the crawler assembly of the embodiment of the present application, if the ground to be driven is steep and muddy, for example, when the user drives the ground near the mountain feet, the soil on the ground near the mountain feet is soft and often semi-buries stones belonging to the mountain, the user can control 2 of the 4 crawler driving devices 100 at the upper part to move in the crawler traveling direction through the central control system of the small-sized harvester, the small-sized weeder, the small-sized excavator or the small-sized conveyor vehicle, and operate 2 of the 4 crawler driving devices 100 at the lower part to move in the opposite direction of the crawler traveling direction, at this time, the crawler 300 is in a parallelogram shape, and the crawler 300 has a lower ground pressure, so that the small-sized harvester, the small-sized weeder, the small-sized excavator or the small-sized conveyor vehicle is prevented from being caught in the soil and has a better passing capability, and the small-sized harvester, the small-sized weeder, the small-sized excavator or the small-sized conveyor vehicle can flexibly and quickly pass through the ground near the mountain feet.

As one possibility, in order to ensure that the track 300 does not fall off when the track assembly of the embodiment of the present application is used, the user may add a tensioning structure of the track 300 to the track walking frame 200, the tensioning structure is disposed in the middle of the upper 2 of the 4 track driving wheel sets 100, and the tensioning structure and the track walking frame 200 are fixedly connected, and the tensioning structure and the 4 track driving assemblies 100 support the track 300 together.

Further, it should be noted that when the user needs to adjust the track drive 100, the user should have the small work machine vehicle in a stationary or low speed driving state.

To sum up, the track subassembly that this application embodiment disclosed can change the shape of track according to the ground condition, and then promotes the trafficability characteristic and the stability ability of vehicle.

For a better explanation of the present application, in one embodiment of the present application, as shown in fig. 3, the adjustment assembly 102 includes a second beam 1021 and a drive wheel 1022, wherein,

one end of the second beam 1021 is hinged to the first drive unit 103 and the first beam 101, respectively, and the other end of the second beam 1021 is pivotally connected to a drive wheel 1022, wherein the drive wheel 1022 is used to support the track 300.

Specifically, the adjustment of the shape of the crawler 300 is achieved by moving the crawler drive assembly 100 on the crawler travel frame 200, on the one hand, and the adjustment of the shape of the crawler 300 can be further more precisely performed by adjusting the adjustment assembly 102, on the other hand.

When the distance of the track 300 in the transverse direction needs to be adjusted, the first driving device 103 is extended, so that the second beam 1021 is rotated away from the first beam 101 along the joint of the first beam 101 and the second beam 1021.

When the distance of the track 300 in the longitudinal direction needs to be adjusted, the first driving device 103 is shortened, so that the second beam 1021 rotates toward the direction close to the first beam 101 along the joint with the first beam 101 as an axis.

For better explanation of the present application, in one embodiment of the present application, as shown in fig. 4, the crawler travel frame 200 includes a first fixing plate 201, a second fixing plate 202, a third fixing plate 203, and a plurality of third cross members 204, wherein,

the first fixing plate 201, the second fixing plate 202 and the third fixing plate 203 are sequentially and equally spaced apart.

The middle part of the third beam 204 penetrates through the second fixing plate 202, and two ends of the third beam 204 are respectively and fixedly connected with the first fixing plate 201 and the third fixing plate 203, wherein the third beam 204 is movably connected with the track driving assembly 100.

The first beam 101 is provided with a through hole 105 penetrating through two ends of the first beam, and the first beam 101 is sleeved on the outer wall of the third beam 204 through the through hole 105.

The cross section of the through hole 105 and the cross section of the third beam 204 are both T-shaped or both I-shaped.

The end of the second driving device 104 remote from the first beam 101 is fixedly connected to the second fixing plate 202.

Specifically, when assembling the crawler travel frame 200, a worker may add a reinforcing rib to the first fixing plate 201, the second fixing plate 202, the third fixing plate 203, and the third cross member 204, and may add a reinforcing rib or a reinforcing beam to the connection portion between the first fixing plate 201, the second fixing plate 202, the third fixing plate 203, and the third cross member 204, thereby making the crawler travel frame 200 more stable.

It should be noted that the number of the third cross beams 204 is at least 2, and the number of the third cross beams 204 is not too large, and the too large number of the third cross beams 204 increases the cost of the embodiment of the present application, and the too large number of the third cross beams 204 occupies the payload of the track driving wheel set 200, thereby significantly reducing the payload of the embodiment of the present application.

As a possibility, in order to ensure that the first beam 101 can move on the third beam 104 normally, the related staff needs to pay heavy attention to the first beam 101 and the third beam 104 regularly, for example, the related staff regularly uses a brush or a high-pressure water gun to clean dirt on the surface of the third beam 104, especially clean sundries in the gap between the first beam 101 and the third beam 104.

In addition, when assembling the crawler belt walking frame 200, the worker may use a canvas cover to cover the outer wall of the third cross member 104, one end of the canvas cover is connected to the second fixing plate 202 through a connector, and the other end of the canvas cover is connected to the first cross member 101 through a connector.

For the purpose of the present application, it is assumed, for example, that the track assembly described above is applied to a light excavator, wherein the relevant worker can observe and judge the ground conditions while driving the light excavator, and manipulate the track assembly to change the shape through a control panel of the light excavator. For example, when the ground is flat and regular, the related staff may adjust the crawler 300 to be a parallelogram, when the ground is rough and steep, the related staff may adjust the crawler 300 to be a regular trapezoid, and when the ground has more sundries, the related staff may adjust the crawler 300 to be an inverted trapezoid.

In addition, if the light excavator equipped with the crawler assembly is equipped with an image recognition device, the crawler assembly may be connected to the image recognition device through a central control system of the light excavator.

Specifically, real-time monitoring and analysis of the ground conditions are realized by the image recognition device in cooperation with an image recognition technology, and the light excavator can automatically control the track assembly to change the shape based on the analysis result of the image recognition device on the ground conditions.

It should be noted that when the track assembly is converted in shape, the light excavator equipped with the track assembly can be in a stationary or low speed driving state. For example, when the light construction machine runs at a speed of 5 km/h or less, the relevant worker or the image recognition device can freely control the track assembly to change the shape through the control panel of the light construction machine.

Moreover, when the light weight excavator equipped with the crawler assembly and the image recognition device travels on the very rugged and steep ground at a speed of less than 5 km/h, the light weight excavator can forcibly stop the conversion of the crawler assembly based on the analysis result of the image recognition device on the ground condition to prevent the light weight excavator from accidents such as rollover, toppling and the like.

Further, it should be noted that, for a light excavator equipped with the track assembly and equipped with the image recognition device, the priority of manual control of the track assembly of the light excavator by the relevant worker may be greater than the priority of automatic control of the track assembly of the light excavator by the image recognition device.

In summary, according to the track assembly in the embodiment of the present application, the relative position between the track driving wheel set and the track traveling frame can be adjusted according to the ground condition, and the shape of the track driving wheel set is adjusted, so that the shape of the track is changed, and finally, the traveling performance of the light engineering machine using the track assembly is improved.
