Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering vehicle technology, and in particular to a tracked vehicle. Background Technology
[0002] Tracked vehicles are widely used in engineering construction, mining, and agriculture due to their excellent off-road performance and load-bearing capacity. However, traditional tracked vehicles have revealed many design flaws under complex working conditions. For example, the unreasonable center of gravity distribution of the rectangular frame leads to poor stability when operating on slopes, making them prone to rollover accidents; the track shoes have insufficient anti-slip performance, making them prone to slipping on muddy or icy roads, reducing work efficiency and increasing energy consumption; the simple connection structure between the working device and the vehicle body limits the range of motion of the working parts, making it difficult to adapt to multi-angle digging and loading needs; the bucket edges have poor wear resistance, and frequent replacement of parts increases operating costs; the cab protection design is weak, making operators vulnerable to impacts from falling rocks, branches, and other foreign objects; the drive box's heat dissipation structure is inefficient, leading to excessively high internal temperatures and shortening the service life of the engine and transmission system. These problems urgently need to be solved through structural innovation and optimized design. Utility Model Content

[0023] The cockpit 4 is located on the cockpit mounting platform 12, with an integrally formed arc-shaped protective cover 41 extending forward.
[0024] According to the present invention, the tracked vehicle is provided in which the track chain 23 is composed of track plates that are hinged together in sequence, and each track plate has anti-slip teeth on its ground surface.
[0025] According to the present invention, the front edge of the bucket is inlaid with a hard alloy trim, and it is provided with two side plates 33, which are inclined outward at 15-20° to form a flared structure.
[0026] According to the present invention, a tracked vehicle has raised handrails 42 integrally formed on both sides of the front end of the arc-shaped protective top cover 41, and the surface of the handrails 42 is provided with anti-slip texture.
[0027] According to the present invention, a tracked vehicle is provided with a rectangular mesh-shaped heat dissipation grille 131 on the rear side wall of the drive box 13. The mesh of the heat dissipation grille 131 has square holes, and the grille frame is fixed to the side wall of the drive box 13 by bolts.
[0028] Working Principle: The overall operation of a tracked vehicle relies on the coordinated operation of its various components. Among them, the vehicle body 1, as the core load-bearing structure, plays a crucial role in power transmission and operational processes. The vehicle body 1 adopts a trapezoidal frame structure that is narrow at the front and wide at the rear. This design optimizes the overall center of gravity distribution, providing basic stability for the vehicle when operating in complex terrain. The wide rear structure enhances the vehicle's anti-rollover capability during travel and operation, allowing it to disperse stress through its structural characteristics when running on slopes or soft ground, thus avoiding imbalance caused by a shift in the center of gravity.
[0029] The double-hinged lugs 11 on both sides of the front of the vehicle body 1 are key nodes for connecting the working device 3. Their symmetrical distribution provides stable rotational support for the parallel double-hinged shaft 31 of the working device 3. When the drive cylinder 32 is activated, the double-hinged lugs 11, through rotational engagement with the parallel double-hinged shaft 31, constrain the movement trajectory of the bucket, ensuring that it maintains a precise range of motion during tilting and lifting operations, and avoiding operational deviations caused by loose connections.
[0030] The cab mounting platform 12 in the middle of the vehicle body 1 provides a rigid and fixed foundation for the cab 4, ensuring the stability of the connection between the cab 4 and the vehicle body 1. This stable connection allows the operator to operate stably through the control system in the cab 4 when the vehicle is bumpy or vibrating during operation, reducing operational delays caused by installation gaps.
[0031] The drive box 13 integrated at the rear of the vehicle body 1 is the core hub for power distribution. The integrated transmission gear set converts the engine output torque into power parameters adapted to the tracked walking mechanism 2. The drive box 13 transmits power through the drive sprocket 21 on the power axis. Its housing is made of high-strength cast iron, capable of withstanding the radial and axial loads during the operation of the drive sprocket 21, while also providing fixed support for the drive cylinder 32. The rigid connection between the end of the drive cylinder 32 and the drive box 13 ensures that the thrust generated during its extension and retraction movements is efficiently transmitted to the parallel double-hinged shaft 31, enabling precise bucket operation. Furthermore, the rectangular mesh-like heat dissipation grille 131 on the rear side wall of the drive box 13 dissipates heat generated by gear meshing within the box rapidly through air convection. Its square hole structure ensures sufficient heat dissipation area while preventing external debris from entering the box, maintaining the cleanliness of the drive box 13 and ensuring long-term stable operation of the transmission system.
[0032] The operation of the tracked walking mechanism 2 relies on the power transmitted by the vehicle body 1: the drive sprocket 21 rotates under the drive of the drive shaft of the drive box 13, driving the track chain 23 to circulate along the trajectory formed by the drive sprocket 21, the driven sprocket 22, and the guide wheel 24. The meshing design of the guide wheel 24 and the internal teeth of the track chain 23 limits the lateral displacement of the track chain 23 through tooth profile matching, preventing it from derailing when the vehicle turns or encounters bumps. Meanwhile, the anti-slip teeth on the ground contact surface of the track plates of the track chain 23 increase the friction with the ground, and combined with the trapezoidal structure of the vehicle body 1, enhance the overall grip, ensuring the vehicle's stability on complex road surfaces such as mud and gravel.
[0033] The working action of the working device 3 is achieved by the coordinated operation of the drive cylinder 32 and the parallel double-hinged shaft 31: when the operator issues a command through the control element in the cab 4, the piston rod of the drive cylinder 32 extends and retracts, pushing the parallel double-hinged shaft 31 to rotate around the double-hinged lug 11, thereby driving the bucket to complete digging, lifting, unloading and other actions. The carbide trim 32 at the front end of the bucket bears the main wear when in contact with the material, and its hardness characteristics extend the service life of the bucket.
[0034] The curved protective canopy 41 on top of the cab 4 uses a streamlined design to disperse the impact load of falling rocks or foreign objects. Its one-piece molded raised handrail 42 not only facilitates the operator's entry and exit from the vehicle, but also provides a stable grip point when the vehicle is bumpy. The anti-slip texture on the surface increases hand friction and prevents slippage during operation. The entire system, integrated with the vehicle body 1, achieves an organic unity of power transmission, operation execution, and safety protection, forming an efficient and stable operation cycle.
[0035] This utility model provides a tracked vehicle that comprehensively improves its performance and reliability through systematic structural improvements. The trapezoidal frame design, narrower at the front and wider at the rear, effectively lowers the vehicle's center of gravity and optimizes weight distribution, ensuring stability even when operating on slopes and enhancing anti-rollover capability compared to traditional rectangular frames. The combination of double-hinged lugs and parallel double-hinged shafts allows the bucket to have a wider swing range, adapting to different digging and loading needs and significantly improving operational flexibility. The track chain is constructed from hinged track plates with anti-slip serrations. The triangular serration design enhances the vehicle's traction on muddy surfaces and shortens braking distance on icy and snowy roads. Simultaneously, the precise meshing of the guide wheels and track chain reduces operating noise and the risk of derailment. The carbide trim embedded at the front of the bucket improves wear resistance and extends service life. The arc-shaped protective roof of the cab is made of high-strength steel plate, capable of withstanding the impact of heavy objects falling from a height. Combined with knurled anti-slip handrails, it provides reliable safety for the operator. The rectangular mesh cooling grille on the rear side wall of the drive housing optimizes the ventilation path, increases the heat dissipation area, and reduces the internal temperature, effectively improving engine efficiency and transmission system reliability.
