Description

Technical Field

[0001] This invention belongs to the technical field of tracked vehicle suspension arrangement and track tensioning, specifically relating to a ring-type track installation device and installation method. Background Technology

[0002] When tracked vehicles are equipped with full-ring belt tracks, using a traditional drive train arrangement, although belt tracks offer a degree of flexibility, their high longitudinal stiffness and stable pitch result in relatively small longitudinal tensile stress. This makes assembly extremely complex and difficult due to limitations imposed by wheel train space, track adjuster stroke, and guide teeth. It requires significant manpower and is time-consuming, and poses potential safety risks, making it challenging to successfully install full-ring belt tracks onto the vehicle. Therefore, there is an urgent need to research a full-ring belt track installation device and method to solve the technical problem of the inability to install full-ring belt tracks. Summary of the Invention

It is used to support the upper track section, change the direction of movement of the track section relative to the entire track ring, adjust the tightness of the track ring, and guide the track. The split idler wheel consists of an upper idler wheel and a lower idler wheel. The idler wheel is machined with positioning adjustment holes, which cooperate with the positioning adjustment holes on the positioning adjustment device to adjust the position of the idler wheel when it is installed.

[0008] The articulated boom assembly consists of an idler wheel hub and an articulated boom. One end of the articulated boom is fixedly connected to the idler wheel hub, and the idler wheel is also fixedly connected to the idler wheel hub. The idler wheel hub contains a bearing that drives the idler wheel to rotate. The other end of the articulated boom is fixedly connected to the idler wheel bracket.

The positioning adjustment device is a detachable auxiliary installation device with a disc-shaped structure. It is fixedly connected to the idler wheel bracket and has multiple positioning adjustment holes with the same pitch circle diameter as the positioning adjustment holes on the idler wheel. It is used to assist in adjusting the position of the idler wheel during assembly and is removed after the idler wheel and track are assembled.

[0009] The auxiliary mounting plate is a detachable structure with annular grooves that mate with the track guide teeth for guiding the track guide teeth. The auxiliary mounting plate is fixedly connected to the idler wheel hub of the boom assembly to protect the idler wheel hub when assembling the track. The auxiliary mounting plate has multiple positioning adjustment holes that mate with the corresponding positioning adjustment holes on the idler wheel and positioning adjustment device for adjusting the position of the idler wheel.

[0010] Furthermore, the upper and lower inducer wheels are designed symmetrically.

[0011] Furthermore, one end of the crank arm is fixedly connected to the idler wheel hub via a slotted nut and a wire pin.

[0012] Furthermore, the other end of the crank arm is fixedly connected to the guide wheel bracket via a limiting mechanism and bolts.

[0013] Furthermore, the idler wheel bracket is welded to the vehicle body.

[0014] Furthermore, the idler wheel bracket has an arched structure with a curved arm mounting interface, the interface protruding from the vehicle body surface.

[0037] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0038] This embodiment proposes a ring-type track mounting device, which mainly includes a split idler wheel 4, a crank arm assembly 5, a positioning adjustment device 3, an idler wheel bracket 6, and an auxiliary mounting plate 7.

[0039] The split-type idler wheel 4 is mounted on the crank arm assembly 5 of the track tensioning mechanism. It supports the upper track section, changes the direction of movement of the track section relative to the entire track ring, adjusts the tension of the track ring, and guides the track. The split-type idler wheel 4 consists of two symmetrical parts, such as... Figure 2a and 2b As shown, it consists of an upper inducer wheel 41 and a lower inducer wheel 42. The inducer wheel 4 is machined with a positioning adjustment hole, which cooperates with the positioning adjustment hole on the positioning adjustment device 3 to adjust the position of the inducer wheel 4 during installation.

[0040] like Figure 3 As shown, the crank arm assembly 5 consists of an idler wheel hub 51 and a crank arm 52. One end of the crank arm 52 is fixedly connected to the idler wheel hub 51 via a slotted nut and a wire pin. The idler wheel 4 is fixedly connected to the idler wheel hub 51 via a nut. The idler wheel hub 51 contains a bearing that can drive the idler wheel 4 to rotate. The other end of the crank arm 52 is fixedly connected to the idler wheel bracket 6 via a limiting mechanism and bolts. The idler wheel bracket 6 is welded to the vehicle body 1. The idler wheel bracket 6 has an arched structure and is used to connect the vehicle body 1 and the crank arm assembly 5. It has a crank arm mounting interface. To ensure the track center distance, the interface protrudes from the surface of the vehicle body 1. The idler wheel bracket 6 is designed with bolt holes for mounting the limiting mechanism. The positioning adjustment device 3 is a detachable auxiliary installation device with a disc-shaped structure. It is fixedly connected to the idler wheel bracket 6 by bolts. The positioning adjustment device 3 has multiple positioning adjustment holes with the same pitch circle diameter as the positioning adjustment holes on the idler wheel 4. It is used to assist in adjusting the position of the idler wheel 4 during assembly and is removed after the idler wheel 4 and the track 2 are assembled.

[0041] The auxiliary mounting plate 7 is a detachable structure, machined with annular grooves that mate with the track guide teeth for guiding the track guide teeth, such as... Figure 4 As shown. The auxiliary mounting plate 7 is fixedly connected to the idler wheel hub 51 of the crank arm assembly 5 by a nut, and is used to protect the idler wheel hub 51 when assembling the track 2, as shown. Figure 5 As shown, the auxiliary mounting plate 7 is machined with multiple positioning adjustment holes, which cooperate with the corresponding positioning adjustment holes on the inducer wheel 4 and the positioning adjustment device 3 to adjust the position of the inducer wheel 4.

[0042] The installation method using the above-mentioned ring-type track mounting device includes the following steps:

[0043] S1. Install the crank arm assembly 5 onto the idler wheel bracket 6, as follows: Figure 6 As shown.

[0044] S2. Secure the positioning adjustment device 3 to the guide wheel bracket 6 using bolts, such as Figure 7 As shown.

[0045] S3. Install the idler wheel 41 and auxiliary mounting plate 7 onto the idler wheel hub 51 of the crank arm assembly 5, and use a tool to fix their relative positions through the positioning adjustment holes, such as... Figure 8 As shown.

[0046] S4. Fine-tune the upper idler wheel 41 and install the full-ring belt track 2, as follows. Figure 9 As shown.

[0047] Since the track guide teeth at the idler wheel 4 are not subject to lateral displacement restriction, the installation of the full-ring track 2 will not be affected.

[0048] S5. Adjust and fix the upper inducer 41 so that the angle between the dividing line of the inducer 4 and the horizontal direction is within the range of 40° to 90°. Remove the auxiliary mounting plate 7. Figure 10 As shown.

[0049] S6. Fine-tune the upper idler wheel 41, adjust the belt track 2, and install the lower idler wheel 42 on the idler wheel hub 51 of the boom assembly 5. After installation, remove the positioning adjustment device 3. Figure 11 As shown.

[0050] The integral ring track installation device and method provided by the present invention can achieve simple, fast, reliable and safe assembly of integral ring track under the constraints of space and structure, and without changing the original wheel system arrangement as much as possible, by replacing the idler wheel and adding a detachable auxiliary installation device.

[0051] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
