Description

Technical Field

[0001] This invention relates to the field of engineering machinery, specifically to an anti-rollover mechanism and a tracked vehicle. Background Technology

[0002] my country, with its vast territory and large population, is prone to frequent disasters such as fires, floods, snowstorms, and earthquakes, which seriously threaten the lives and property of its citizens. On the other hand, with rapid urbanization, various emergencies have increased dramatically, causing severe losses of life and property. For example, in 2013, the number of deaths due to accidents and disasters in my country reached 69,000, with direct economic losses of 580.84 billion yuan, accounting for approximately 1% of GDP. These disasters and accidents are characterized by diversity and complexity, posing enormous challenges to post-disaster relief and reconstruction. However, the technological level of my country's disaster emergency rescue equipment is severely lagging behind, with limited functionality and low specialization, leading to untimely and inefficient rescue efforts. In particular, the complex terrain and geological conditions after a disaster severely restrict the mobility of emergency rescue equipment, resulting in lost precious rescue time.

[0003] Tracked vehicles are widely used in disaster relief and rescue operations. However, tracked vehicles operate in harsh environments with complex geological conditions, making them prone to overturning.

[0004] The inventors discovered that in order to reduce the chance of overturning, the track wheel device of tracked vehicles is equipped with an elastic buffer. However, this structure is not only large and loose, but also not conducive to steering. Summary of the Invention

[0076] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0077] The dimensions of the various parts shown in the accompanying drawings are not drawn to actual scale. Common structural elements or elements of the same kind are given the same reference numerals in the various drawings, and repeated descriptions of them are omitted where appropriate.

[0078] See Figure 1 This invention provides an anti-tilting mechanism 30, which includes a connecting member 1, a pull rod 2, a torsion bar assembly 3, and a torsion spring assembly 4. The connecting member 1 includes a first connecting end 11, a second connecting end 12, and a connecting hole 13; the connecting hole 13 is located between the first connecting end 11 and the second connecting end 12. The first end of the pull rod 2 is rotatably connected to the connecting member 1 through the connecting hole 13. The torsion bar assembly 3 includes a connecting member 31 and a sleeve 32 fixedly or detachably connected to the connecting member 31; the sleeve 32 includes a non-circular mounting hole 321. The torsion spring assembly 4 includes a non-circular member 41, a housing assembly 42, and an elastic component 43; one end of the non-circular member 41 is inserted into the non-circular mounting hole 321, the other end of the non-circular member 41 is inserted into the housing assembly 42, and the elastic component 43 is installed between the other end of the non-circular member 41 and the inner wall of the housing assembly 42.

[0079] See Figure 5 and Figure 6The connecting member 1 includes a first connecting end 11 and a second connecting end 12 that are separated from each other. Different positions of the steering knuckle 20 can be connected through the first connecting end 11 and the second connecting end 12. This structure makes the connecting member 1 and the steering knuckle 20 not fixed at a single point, but at multiple points, making the fixation more stable and reliable, and also making the load-bearing capacity of the connecting member 1 stronger during vehicle operation.

[0080] See also Figure 5 and Figure 6 In some embodiments, the connecting member 1 is configured as a C-shape; the first connecting end 11 is one of the two ends at the opening 1a of the connecting member 1, and the second connecting end 12 is the other of the two ends at the opening 1a of the connecting member 1; the connecting hole 13 is located in the middle of the connecting member 1.

[0081] Specifically, the connecting member 1 includes a flat plate 14 with an opening 1a, and two connecting bent plates 15 welded to or integrally cast with the flat plate 14. The connecting bent plates 15 are approximately perpendicular to the flat plate 14. The two connecting bent plates 15 have the same structure and are bent in opposite directions. Each connecting bent plate 15 has a narrower end and a wider end. The narrower end of the connecting bent plate 15 is provided with a slot 151 into which the flat plate is inserted. The wider end of the connecting bent plate 15 is flat and has at least two bolt holes 152. Both connecting bent plates 15 are bolted to the steering knuckle 20 through the bolt holes 152. A reinforcing rib 16 is provided at the wider end of each connecting bent plate 15, and the reinforcing rib 16 is welded and fixed to the connecting bent plate 15. The reinforcing rib 16 can increase the stiffness and strength of the wider end of the connecting bent plate 15 and improve the load-bearing capacity of the connecting bent plate 15.

[0082] A connecting hole 13 is provided in the middle of the plate, which is used for rotatable connection with one end of the tie rod 2. Specifically, a relatively loose bolt connection can be used to achieve the rotatable connection between the plate and the connecting member 1. The position of the connecting hole 13 on the plate is constructed to be protruding to increase the structural strength of the connecting hole 13 and improve the load-bearing capacity of the plate.

[0083] In some embodiments, the housing assembly 42 includes a base plate assembly 421, a first cover plate assembly 422, and a second cover plate assembly 423. The base plate assembly 421 includes a first curved plate 4211 and a plurality of first upright plates 4212 located within a recess of the first curved plate 4211; the plurality of first upright plates 4212 are arranged in parallel and dispersedly. The first cover plate assembly 422 includes a second curved plate 4221 and a plurality of second upright plates 4222 located within a recess of the second curved plate 4221; the plurality of second upright plates 4222 are arranged in parallel and dispersedly; the first cover plate assembly 422 covers a portion of the recess of the first curved plate 4211. The second cover plate assembly 423 includes a third curved plate 4231, a plurality of third upright plates 4232 located in the recess of the third curved plate 4231, and a blocking member 4233; the plurality of third upright plates 4232 are arranged in parallel and dispersedly; the second cover plate assembly 423 covers the remaining recess of the first curved plate 4211; the blocking member 4233 is located on the outside of one end of the third curved plate 4231 and is fixedly connected to the third curved plate 4231.

[0084] See Figure 5 and Figure 7 The tie rod 2 includes a straight rod 21 and a bent stiffener 22. Both ends of the straight rod 21 have mounting through holes 211. One end of the straight rod 21 has a mounting through hole 211 rotatably connected to the connecting member 1, and the other end has a mounting through hole 211 rotatably connected to the torsion bar assembly 3. A bent stiffener 22 is fixed in the middle region of the tie rod 2, and the bent stiffener 22 is perpendicular to the straight rod 21. The bent stiffener 22 and the straight rod 21 can be integrally formed or fixed as a rod. The bent stiffener 22 increases the strength of the tie rod 2.

[0085] See Figure 5 and Figure 8 The connecting piece 31 and sleeve 32 of the torsion bar assembly 3 can be fixedly connected or detachably connected by bolts or other means. The connecting piece 31 can be made of plate. The side of the connecting piece 31 that will not interfere with other components is set as a bent edge, which can increase the structural strength of the connecting piece 31. The connecting piece 31 is generally elongated, and one end of the connecting piece 31 in the length direction is provided with a pointed tip, and the pointed tip is provided with at least two round holes. It is rotatably connected to the other end of the pull rod 2 through one of the round holes. Specifically, the rotatable connection can be achieved by a relatively loose bolt connection. The connecting piece 31 has multiple round holes, which can adjust the installation position of the other end of the pull rod 2 and the connecting piece 31 to adapt to the installation requirements of different products and different working conditions.

[0086] See also Figure 5 and Figure 8The sleeve 32 and the connector 31 are fixed with multiple bolts, making the fixing method more stable and reliable, and the force distribution more even. There is no relative movement between the sleeve 32 and the connector 31. The force on the sleeve 32 is transmitted to the connector 31, and the force on the connector 31 is also transmitted to the sleeve 32. The connector 31 blocks the opening 1a at one end of the sleeve 32, so that only the other end of the sleeve 32 is open.

[0087] See also Figure 8 In some embodiments, the torsion bar assembly 3 further includes a stop member 33, which is mounted on the outside of the sleeve 32 and is configured to extend into the sleeve 32 to abut against the portion of the non-circular member 41 located within the non-circular mounting hole 321. The stop member 33 is located at the open end of the sleeve 32. Because the non-circular member 41 of the torsion spring assembly 4 is inserted into the sleeve 32 through the open end of the sleeve 32, the stop member 33 abuts against the non-circular member 41 closer to the middle position, rather than the end of the non-circular member 41 inserted into the sleeve 32. This makes the stress point of the non-circular member 41 closer to the middle position, avoiding the unstable stress and loose abutment caused by the stop member 33 acting at the end, making the non-circular member 41 more stable after installation and with better stress characteristics.

[0088] See also Figure 5 and Figure 8 In some embodiments, there are multiple abutment members 33, which are distributed around the exterior of the housing. Specifically, two or four abutment members 33 may be provided, and the non-circular member 41 adopts a cuboid structure. A abutment member 33 is provided on each side of the sleeve 32, and each abutment member 33 abuts against one side of the non-circular member 41. The non-circular member 41 is subjected to balanced forces.

[0089] See Figures 9 to 16 The following section details the specific implementation of the torsion spring assembly 4.

[0090] The torsion spring assembly 4 includes a non-circular member 41, a housing assembly 42, and an elastic component 43. The non-circular member 41 passes through the housing assembly 42 and is inserted into the sleeve 32. The elastic component 43 is located in the gap between the non-circular member 41 and the housing assembly 42. After the elastic component 43 is installed, it is compressed. The elastic component 43 serves to dampen vibration and limit the rotation of the non-circular member 41. One end of the non-circular member 41 is inserted into the non-circular mounting hole 321 of the sleeve 32 described above, and the other end of the non-circular member 41 is inserted into the housing assembly 42. The housing assembly 42 itself is also open at one end 1a, and the other end is not completely open. The other end of the non-circular member 41 can only be inserted through one end of the housing assembly 42. After insertion, both ends of the non-circular member 41 are blocked and limited by the connecting piece 31 of the housing assembly 42 and the torsion bar assembly 3, respectively, and the non-circular member 41 cannot detach from the housing assembly 42 and the torsion bar assembly 3.

[0091] See Figure 9 The non-circular component 41 is relatively long, while the inner cavity of the housing assembly 42 is relatively short. In the normal installation state, only one end of the non-circular component 41 is located on the inner wall of the housing assembly 42, while the other end is located outside the housing assembly 42 and inserted into the sleeve 32. There can be a certain gap between the sleeve 32 and the housing assembly 42, meaning that a portion of the non-circular component 41 is neither located in the sleeve 32 nor in the housing assembly 42.

[0092] See also Figure 9 The non-circular component 41 includes a square tube 411 and a baffle 412. The baffle 412 is fixed to the end of the square tube 411 away from the sleeve 32. The baffle 412 is located outside the housing assembly 42 and serves to block the gap between the housing assembly 42 and the square tube 411, preventing the elastic component 43 located between the square tube 411 and the housing assembly 42 from falling off the end of the housing assembly 42. The square tube 411 is hollow, has a high load-bearing capacity, and is lightweight.

[0093] See Figures 9 to 14 The bottom plate assembly 421, the first cover plate assembly 422, and the second cover plate assembly 423 all include bent plates. The first bent plate 4211 of the bottom assembly, the second bent plate 4221 of the first cover plate assembly 422, and the third bent plate 4231 of the second cover plate assembly 423 are all spliced ​​together to form a cavity for accommodating the non-circular component 41 and the elastic component 43.

[0094] See Figures 12 to 14In some embodiments, the first bent plate 4211, the second bent plate 4221, and the third bent plate 4231 have the same structure, and each includes a concave plate 424, a first bent edge 425, and a second bent edge 426. The concave plate 424 includes a first side plate 4241, a second side plate 4242, and a bottom plate 4243; the first side plate 4241 and the second side plate 4242 are fixed to both sides of the bottom plate 4243. The first bent edge 425 is fixedly connected to the edge of the first side plate 4241 away from the bottom plate 4243. The second bent edge 426 is fixedly connected to the edge of the second side plate 4242 away from the bottom plate 4243.

[0095] The first bent plate 4211, the second bent plate 4221, and the third bent plate 4231 can all adopt an integral structure, which can be cast or formed by bending a single plate. Specifically, the concave plate 424, the first bent edge 425, and the second bent edge 426 are constructed as a single unit.

[0096] In some embodiments, the first bent edge 425 of the first bent plate 4211 is detachably and fixedly connected to the first bent edge 425 of the second bent plate 4221 and the first bent edge 425 of the third bent plate 4231; the second bent edge 426 of the first bent plate 4211 is detachably and fixedly connected to the second bent edge 426 of the second bent plate 4221 and the second bent edge 426 of the third bent plate 4231. The bends of the bent edges can be detachably connected using multiple bolts.

[0097] In the specification embodiment described above, the non-circular component 41 is constructed as a cuboid, and the non-circular mounting hole 321 is also a rectangular hole. The shape of the non-circular mounting hole 321 matches the shape of the non-circular component 41. The angle α between the side of the non-circular component 41 and the first side plate 4241 is 40° to 50°, specifically, for example, 40°, 45°, or 50°.

[0098] In some embodiments, the non-circular member 41 is located within the space enclosed by the first upright plate 4212, the second upright plate 4222, and the third upright plate 4232, and the rotation range of the non-circular member 41 within the non-circular mounting hole 321 is limited by the first upright plate 4212, the second upright plate 4222, and the third upright plate 4232.

[0099] In some embodiments, the first upright plate 4212, the second upright plate 4222, and the third upright plate 4232 all include a protruding tip b, and the minimum distance § between the protruding tip b and the non-circular member 41 is 1mm to 6mm. The protruding tip b makes it easier to install the non-circular member 41 and allows the rotation of the non-circular member 41 to be controlled within a smaller range. The apex angle of the protruding tip b is β, which is 120° to 170°, specifically, for example, 120°, 130°, 140°, 150°, 160°, or 170°. The larger the apex angle of the protruding tip b, the smaller the allowable swing angle of the triangular rubber track assembly 60.

[0100] See Figures 9 to 16 The elastic component 43 includes a cylindrical rubber; the non-circular mounting hole 321 is constructed as a square hole, and the non-circular member 41 is constructed as a cuboid. The elastic component 43 is installed in the gap between the non-circular mounting hole 321 and the non-circular member 41, and at each corner of the non-circular mounting hole 321.

[0101] In some embodiments, the side length of the non-circular mounting hole 321 is The elastic component 43, i.e., the cylindrical rubber, has a diameter of [missing information]. ;in Specifically, values ​​such as 0.3, 0.35, 0.38, and 0.4 are used. The larger the diameter of the cylindrical rubber, the greater the stiffness of the torsion spring assembly 4, and the greater the torsional force provided, making it suitable for preventing rollovers in heavier vehicles.

[0102] In some embodiments, the side length of the non-circular mounting hole 321 is The side length of the square tube 411 is ;in Specifically, for example, 0.4, 0.45, 0.5, 0.55, and 0.6. Side length The larger the size, the stronger the structural load-bearing capacity, making it suitable for preventing rollover of heavier tracked vehicles.

[0103] See Figures 1 to 3 , Figures 18 to 20 This invention also provides a tracked vehicle, including a frame 10, a steering knuckle 20, and an anti-rollover mechanism 30 provided by any of the technical solutions of this invention. The first connecting end 11 and the second connecting end 12 of the connecting member 1 of the anti-rollover mechanism 30 are both fixedly connected to the steering knuckle 20 by bolts; the housing assembly 42 of the torsion spring assembly 4 is detachably fixedly connected to the frame 10.

[0104] High-speed tracked assemblies can significantly improve the ability of emergency rescue vehicles to cope with complex geological and terrain conditions after disasters, such as muddy and soft ground, and improve the efficiency of emergency rescue. They are widely used in disaster relief, agricultural machinery, military equipment, special equipment, engineering machinery and snow machinery.

[0105] See Figures 18 to 20 The tracked vehicle includes an axle 40, a suspension assembly 50, and a triangular rubber track assembly 60. The triangular rubber track assembly 60 is also known as a high-speed track assembly. The triangular rubber track assembly 60 includes a rubber track 601, a drive wheel 602, a road wheel 603, a guide wheel 604, a tension wheel 605, a frame 607, and a gas spring 608. The drive wheel 602 is located at the upper part of the triangular rubber track 601 and is mainly used to transmit power. Power is transmitted from the chassis axle to the drive wheel 602, which meshes with the rubber track 601 to transmit power. The guide wheel 604 and the tension wheel 605 are located at the bottom ends of the triangular rubber track 601, guiding the rubber track 601 and providing approach and departure angles, while also tensioning the rubber track 601. The road wheel 603 is located at the bottom of the triangular rubber track 601 and is rotatably mounted on the frame 607, forming the road wheel system, which is the main load-bearing structure of the triangular rubber track assembly 60. The frame 607 maintains the structure of the triangular rubber track assembly 60 and is used to install components such as the drive wheel 602, guide wheel 604, and road wheel 603.

[0106] The rubber track 601 is located on the outside of the triangular rubber track assembly 60. It transmits power to drive the whole vehicle and needs to have good grip performance, impact resistance, wear resistance and light structural weight.

[0107] The tensioning device 606 mainly includes a hydraulic cylinder and an accumulator. The hydraulic cylinder stores hydraulic oil, and the gas and hydraulic oil stored in the accumulator form a pneumatic-hydraulic spring to achieve tensioning and cushioning of the rubber track.

[0108] During operation, the frame 607 of the triangular rubber track assembly 60 can still swing around the central axis of the axle 40, which may cause excessive swinging of the triangular rubber track assembly 60 and interference with the frame 10. Figure 1 As shown.

[0109] The anti-rollover mechanism 30 constitutes a four-bar linkage; specifically, the connecting component 1 and the steering knuckle 20 form a single unit. Figure 3 The diagram in L shows the centerline of the drive wheel and the connection hole 13 of the connecting member 1 (see Figure 1). Figure 6 The distance between them. When the tracked vehicle travels on uneven ground, the high-speed rubber track assembly remains in contact with the ground, and the frame 607 of the triangular rubber track assembly 60 swings around the axis of the drive flange (which is also the flange of the steering knuckle 20). This drives the tie rod 2 and the torsion bar assembly 3 to move, and the included angle between the tie rod 2 and the torsion bar assembly 3 increases or decreases. When the angle change of the square tube 411 reaches its limit, that is, after the square tube 411 collides with the side of the third vertical plate 4232, the mechanism forms a mechanical limit, and the angle cannot be increased further. The angle change of the torsion spring 4 naturally generates a reaction force, thereby limiting the overturning of the high-speed rubber track assembly.
