TECHNICAL FIELD

[0001] The present application relates to the technical field of the supporting and suspending mechanism of the track walking mechanism, and particularly relates to a torsional spring and spring combined shock-absorbing supporting and suspending mechanism. BACKGROUND

[0002] The supporting and suspending mechanism is a key component on equipment such as a tracked or wheeled vehicle, and is mainly used for connecting a vehicle body and a supporting wheel (for a tracked vehicle) or a wheel (for a wheeled vehicle), and plays a role of supporting, buffering, shock-absorbing and uniformly distributing load.

[0004] At present, the commonly used supporting and suspending mechanism of the tracked walking mechanism in the prior art is usually composed of a torsional spring, a spring, a supporting wheel and the like. When the vehicle drives on a rugged road, the supporting wheel will move up and down with the ups and downs of the road. At this time, the spring and the torsional spring will be deformed correspondingly, such as the spring being compressed or elongated, and the torsional spring being twisted and rotated under force. However, when the vehicle drives to a depressed position, since the supporting wheel is usually composed of multiple parts, if one of the supporting wheels is located at the depressed position, the supporting wheel may be subjected to a large load impact force, causing the single supporting wheel to bear an excessive load, reducing the shock-absorbing and buffering effect, and the torsional spring is arranged on the suspending mechanism of the supporting wheel for further shock-absorbing and buffering. However, if the supporting wheel bears a large load, the torsional spring will also bear a large load, thereby increasing the stress generated by the torsional spring and reducing the service life of the torsional spring, which is high in use cost. Therefore, the present application provides a torsional spring and spring combined shock-absorbing supporting and suspending mechanism. SUMMARY

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0022] Reference Figures 1 to 5 A torsional spring and spring combined damping load bearing suspension mechanism, comprising a track 1, the inside of the track 1 is provided with a plurality of track traveling wheels 4, the inside of the track 1 is provided with a mounting mechanism 6 and a load bearing mechanism 8 for damping when the track traveling wheels 4 travel; The load bearing mechanism 8 comprises a connecting plate 802, the connecting plate 802 is rotatably connected with a load bearing wheel 801 through a pin shaft, the connecting plate 802 is symmetrically arranged, and the adaptive spring 803 is arranged between the two connecting plates 802, the connecting plate 802 is fixedly connected with a matching rod 804 inside, the mounting mechanism 6 comprises a plurality of mounting shells 601, each mounting shell 601 is fixedly connected with a mounting rod 602 inside, and the surface of the mounting rod 602 is detachably connected with a torsional spring 603.

[0023] The present application considers that when the track 1 and the plurality of track walking wheels 4 constitute the track walking mechanism, in order to ensure that the track 1 can walk smoothly, a plurality of supporting wheels 801 are usually installed on the inner side of the track 1, which can not only support the load of the track 1, but also play the role of buffering and shock absorption, so that the supporting wheels 801 can walk smoothly, but since the supporting wheels 801 are usually assembled in pairs inside the track 1, a stable triangular state is formed between the two supporting wheels 801 and the inner side of the track 1, which can stably support and uniformly distribute the load, but if a concave position is encountered, at this time, the two supporting wheels 801 may move relatively, so that the distance between the two supporting wheels 801 is shortened, which destroys the stable triangular state formed between the two supporting wheels 801 and the inner side of the track 1, and at this time, if the two supporting wheels 801 move relatively and are both in the concave position, the two supporting wheels 801 in the concave position will bear more load due to gravity, so that the supporting wheels 801 cannot effectively support the track 1 and the load; Therefore, by arranging the adaptive spring 803 on one side of the two supporting wheels 801, when the two supporting wheels 801 move relatively and the distance is shortened, the two supporting wheels 801 will extrude the adaptive spring 803, so that the adaptive spring 803 is forced to compress, which can limit the distance of the relative movement of the supporting wheels 801, and as far as possible to protect the stable triangular state formed between the two supporting wheels 801 and the inner side of the track 1, which can avoid that the two supporting wheels 801 bear more load when they are in the concave position; It should be noted that since the supporting wheels 801 are rotatably connected to the connecting plates 802 by the pin shafts, and the connecting plates 802 are rotatably connected to the inside of the mounting shell 601, when the supporting wheels 801 move relatively and extrude the adaptive spring 803, the adaptive spring 803 will be extruded by the connecting plates 802 when they rotate, so that the adaptive spring 803 changes from a parallel state to a convex state, at this time, the supporting wheels 801 will exert a reverse pushing force on the two connecting plates 802, which not only can improve the stability of the stable triangular state formed between the two supporting wheels 801 and the inner surface of the track 1, but also can play the role of buffering and shock absorption, avoiding that the two supporting wheels 801 receive greater impact force and bear more load at the initial stage when they are in the concave position; It should be noted that by arranging the torsional spring 603 on the surface of the mounting rod 602, and connecting the torsional spring 603 below with the matching rod 804 (as shown in Figure 6When the two supporting wheels 801 produce relative motion, the connecting plate 802 on one side of the two supporting wheels 801 will exert extrusion force on the lower part of the torsional spring 603 through the matching rod 804 at this time, so that the torsional spring 603 is subjected to a certain extrusion force, and the torsional spring 603 will also generate a reverse pushing force on the matching rod 804 after being subjected to the extrusion force. On the basis of the reverse pushing of the adaptive spring 803 on the connecting plate 802, the connecting plate 802 is pushed again by the reverse action force of the torsional spring 603, so that a stable triangle shape can be formed between the supporting wheel 801 on one side of the connecting plate 802 and the inner surface of the track 1, so that the supporting wheel 801 can effectively support the track 1 even at the concave position, and the adaptive spring 803 and the torsional spring 603 can also effectively play the role of buffering and shock absorption, avoiding the load and the track 1 from being subjected to large vibration when the track 1 encounters a concave position, and enabling the track 1 to walk stably.

[0024] With reference to Figures 2 to 3 One side of the mounting shell 601 is rotatably connected with the first suspension rod 5 and the second suspension rod 501 through a pin shaft, the second suspension rod 501 and the first suspension rod 5 form a certain angle, and the first damping spring 502 is arranged between the second suspension rod 501 and the first suspension rod 5. One side of the second suspension rod 501 is provided with a suspension bracket 3, and the suspension bracket 3 is arranged in multiple sections.

[0025] When the two supporting wheels 801 are in the concave position and produce relative motion, the supporting wheel 801 will be subjected to a large load impact due to gravity, although the adaptive spring 803 and the torsional spring 603 can buffer and shock absorb to a certain extent, so that the track 1 runs more stably, but in order to further reduce the impact load force borne by the supporting wheel 801, therefore, the first suspension rod 5 and the second suspension rod 501 are rotatably connected on one side of the two mounting shells 601 through a pin shaft, when the supporting wheel 801 moves relatively, the supporting wheel 801 will also drive the mounting shell 601 to move up and down through the connecting plate 802, and the mounting shell 601 will drive the first suspension rod 5 and the second suspension rod 501 which form an angle to swing around the pin shaft, so as to extrude and stretch the first damping spring 502 arranged between the first suspension rod 5 and the second suspension rod 501. At this time, the load force borne by the supporting wheel 801 will be transmitted to the first damping spring 502 through the mounting shell 601, the first suspension rod 5 and the second suspension rod 501, so that the load force borne by the supporting wheel 801 is further shared, which can further improve the stability of the stable triangle shape formed between the supporting wheel 801 and the inner surface of the track 1 when the supporting wheel 801 is in the concave position, and further improve the stability of the track 1 when walking.

[0026] With reference to Figures 6 to 10The inside of the mounting shell 601 is provided with an adjusting mechanism 9 for adjusting the pre-tightening force of the torsion spring 603, the adjusting mechanism 9 comprising two sliding sleeves 906 fixed with the torsion spring 603, the inside of the two sliding sleeves 906 being slidingly connected with sliding blocks 904, and the sliding blocks 904 being connected with buffer springs 905.

[0027] The present application also considers that when the supporting wheels 801 relatively move to drive the connecting plates 802 to rotate in the inside of the mounting shell 601, at this time, the matching rods 804 in the connecting plates 802 will exert extrusion force on the torsion spring 603, so that the torsion spring 603 is extruded to generate reverse acting force, which pushes the connecting plates 802 to drive the supporting wheels 801 to swing reversely, so that the two supporting wheels 801 and the inner surface of the track 1 always form a stable triangular shape, improving the stability of the track 1 movement, but if the torsion spring 603 is subjected to greater extrusion force, the stress may be too large, causing the torsion spring 603 to lose elasticity, so that the torsion spring 603 cannot effectively cooperate with the self-adaptive spring 803 to push the supporting wheels 801, thereby causing damage. Therefore, by fixing two sliding sleeves 906 on both sides below the torsion spring 603, and slidingly connecting sliding blocks 904 in the inside of each sliding sleeve 906, and connecting buffer springs 905 between the two sliding blocks 904, if the torsion spring 603 is subjected to extrusion force from one side of the connecting plate 802 of the supporting wheel 801 at this time, the position of the sliding block 904 in the inside of the sliding sleeve 906 is controlled (as shown in Figures 8 to 10 ), the up and down position of the sliding block 904 in the inside of the sliding sleeve 906, so as to adjust the distance between the buffer spring 905 and the torsion spring 603, if the buffer spring 905 is close to the position of the torsion spring 603, the buffer spring 905 is in the extruded state at this time, which can assist the torsion spring 603 to push the connecting plate 802, if the buffer spring 905 is away from the position of the torsion spring 603, the buffer spring 905 is in the stretched state at this time, which can buffer the extrusion force of the torsion spring 603, thereby effectively reducing the situation that the torsion spring 603 is subjected to greater stress after being contacted with the matching rod 804 due to the influence of the supporting wheel 801, improving the service life of the torsion spring 603. It should be noted that when the two supporting wheels 801 relatively move at this time, the lower part of the torsion spring 603 also relatively moves at this time, at this time, no matter whether the buffer spring 905 is in the position close to the torsion spring 603 or away from the torsion spring 603, when the torsion spring 603 is extruded by the matching rod 804, the torsion spring 603 will exert extrusion force on the buffer spring 905 at this time, so that the buffer spring 905 can effectively eliminate the stress generated in the vertical direction of the torsion spring 603, avoiding that the torsion spring 603 at the connecting position with the matching rod 804 is subjected to greater stress after being subjected to greater extrusion force, affecting the normal use of the torsion spring 603.

[0028] With reference to Figures 8 to 10 , both sides of the sliding block 904 are rotatably connected with the telescopic slide rod 903 through the pin shaft, one side of the telescopic slide rod 903 is fixedly connected with the output end of the electric telescopic rod 902, the upper side of the electric telescopic rod 902 is provided with the driving machine 901, and the driving machine 901 is detachably connected with the mounting shell 601.

[0029] When working, in order to avoid that the connecting plate 802 is swung in the inside of the mounting shell 601 after the supporting wheel 801 is subjected to the lateral extrusion force, at this time the connecting plate 802 exerts the lateral extrusion force on the torsional spring 603 through the matching rod 804, the torsional spring 603 is damaged after the lateral torsion force is generated, if the right side of the torsional spring 603 is subjected to the lateral extrusion force at this time, in order to avoid that the torsional spring 603 cannot effectively perform the buffering and damping work, for example, when the torsional spring 603 is subjected to the extrusion force from the right, at this time the telescopic movement of the electric telescopic rod 902 is controlled by the driving machine 901, which needs to be explained that the driving machine 901 is started according to the sensing of the externally arranged sensor, so that the telescopic movement of the electric telescopic rod 902 is controlled after the sensing of the sensor, which is the prior art, and the present application will not be described in detail, the electric telescopic rod 902 drives the sliding block 904 to slide downward in the inside of the sliding sleeve 906 (as shown in Figure 8 , the buffering spring 905 arranged between the sliding blocks 904 is stretched, at this time the distance between the buffering spring 905 and the torsional spring 603 is far, when the supporting wheel 801 is subjected to the extrusion force from the right in the recessed position, the buffering spring 905 can effectively cooperate with the self-adaptive spring 803 and the torsional spring 603 to buffer and damp the supporting wheel 801, avoid that the supporting wheel 801 is subjected to the large load impact force, improve the stability of the supporting wheel 801, so that the supporting wheel 801 can always form a stable triangle with the inner surface of the track 1, and further improve the stability of the track 1 in walking. For example, if the left side of the torsional spring 603 is subjected to the lateral extrusion force at this time, the position of the left buffering spring 905 is adjusted (as shown in Figure 9 , the distance between the left buffering spring 905 and the torsional spring 603 is far at this time, which can cooperate with the self-adaptive spring 803 and the torsional spring 603 to buffer and damp the supporting wheel 801.

[0030] With reference to Figures 1 to 3 , the third damping spring 11 is rotatably connected with one side of the suspension bracket 3 through the pin shaft, the second damping spring 10 is arranged above a section of the suspension bracket 3, the connecting rod 7 is fixedly connected with one end close to the suspension bracket 3, and the third damping spring 11 and the connecting rod 7 are connected with the track traveling wheel 4.

[0031] When working, in order to avoid the track walking wheel 4 from shaking greatly during movement, thereby reducing the walking stability of the track 1, therefore, the third damping spring 11 is arranged on one side of the suspension bracket 3, and the second damping spring 10 is arranged above the other section of the suspension bracket 3, if the plurality of track walking wheels 4 shake and vibrate at this time, the suspension bracket 3 changes the angle around the rotating shaft, and the second damping spring 10 and the third damping spring 11 can effectively buffer and damp the track walking wheel 4, thereby improving the stability of the track walking wheel 4 driving the track 1 to walk.

[0032] With reference to Figures 3 to 5 , the matching rod 804 is rotationally connected with the mounting shell 601, and one end of the adaptive spring 803 is mounted on the pin shaft of the connecting plate 802 through a sleeve.

[0033] When working, the adaptive spring 803 is arranged between the two connecting plates 802, if the two supporting wheels 801 are in the recessed position at this time, in order to avoid that a single supporting wheel 801 bears a large load, the adaptive spring 803 can also share the load gravity borne by the single supporting wheel 801 at this time, so that the single supporting wheel 801 bears force more evenly, and can avoid fatigue damage of the adaptive spring 803 after reaching the limit due to bearing too large load, and can improve the service life of the adaptive spring 803.

[0034] With reference to Figures 7 to 10 , the driving machine 901 drives the telescopic slide rod 903 to move up and down through the electric telescopic rod 902 to adjust the position of the buffer spring 905, the buffer spring 905 is arranged in an arc shape between the sliding blocks 904, and the telescopic slide rod 903 is arranged in a straight line sliding mode.

[0035] When working, in order to avoid that the adaptive spring 803 and the torsional spring 603 cannot effectively buffer and damp the supporting wheel 801 after the supporting wheel 801 falls into the recessed position initially, and cannot improve the stability of the track 1 supported by the supporting wheel 801, therefore, when the supporting wheel 801 falls into the recessed position initially, the two buffer springs 905 are adjusted to positions away from the torsional spring 603 (as shown in Figure 10 , the impact force generated when the supporting wheel 801 falls can effectively protect the torsional spring 603, so that the torsional spring 603 is not subjected to a large impact load force, thereby avoiding failure, and then the distance between the buffer spring 905 on the left and right sides and the torsional spring 603 is adjusted, so that the buffer spring 905 can eliminate the lateral force generated on the left and right sides of the torsional spring 603, thereby effectively improving the stability of the supporting wheel 801 after falling into the recessed position, and improving the stability of the track 1 supported by the supporting wheel 801.

[0036] With reference to Figures 1 to 3The suspension support 3 is provided with a mounting plate 2 on one side, the multiple rotating shafts of the suspension support 3 are in rotating connection with the mounting plate 2, and the mounting shell 601 is in sliding connection with the mounting plate 2.

[0037] When the mounting shell 601 is subjected to an impact load, the mounting shell 601 drives the first suspension rod 5 and the second suspension rod 501 to swing, the first suspension rod 5 and the second suspension rod 501 exert extrusion force or stretching force on the first damping spring 502, the suspension support 3 is also affected, the third damping spring 11 and the second damping spring 10 can offset the force generated by the up-and-down swing of the mounting mechanism 6, the influence of the first damping spring 502 after being subjected to a load impact force is reduced, deformation and fatigue damage of the first damping spring 502 after being subjected to a large load impact force are avoided, and the stability of the suspension mechanism as a whole is improved.

[0038] With reference to Figures 2 to 5 One end of the third damping spring 11 is in rotating connection with the mounting plate 2 through a sleeve, the second damping spring 10 is arranged obliquely above the suspension support 3, and the connecting rod 7 is in rotating connection with the rotating shaft of the track roller 4.

[0039] When the track 1 is in a walking process, the multiple track rollers 4 drive the track 1 to move as walking wheels, if the track 1 walks to an uneven road section, the suspension support 3 can swing around the rotating shaft, the shape of the multiple track rollers 4 is adjusted, the load force borne by the track rollers 4 is effectively reduced, the track rollers 4 are damped and buffered, the track 1 is prevented from moving unevenly due to a large vibration force borne by the track rollers 4, and the stability of the suspension mechanism as a whole is improved.

[0040] With reference to Figures 2 to 3 The included angle formed above the first suspension rod 5 and the second suspension rod 501 is an acute angle, the included angle formed below the first suspension rod 5 and the second suspension rod 501 is an obtuse angle, the suspension support 3, the first suspension rod 5 and the second suspension rod 501 are connected with the same rotating shaft, and the rotating shaft is fixedly connected with the mounting plate 2.

[0041] When the first suspension rod 5 and the second suspension rod 501 are subjected to a load impact force, the first suspension rod 5 and the second suspension rod 501 can bear a larger impact load, the impact load transmitted to the supporting mechanism 8 is reduced to a certain extent, the stability of the triangle formed between the supporting roller 801 and the track 1 is further improved, and the effect of the supporting roller 801 on the track 1 is further improved.
