Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Example one
An embodiment of the present invention provides a vacuum tire, referring to fig. 1 and 2, the vacuum tire may include a wheel hub 1, a tire 2 mounted on the wheel hub 1, and a flat tire buffer device 3 (see fig. 1 and 2) disposed in a closed space 12 formed between the wheel hub 1 and the tire 2, referring to fig. 3 and 4, the flat tire buffer device 3 may include a rim 31, a rim 32, a connecting rod 33, and a bidirectional cylinder 34, the rim 31 and the rim 32 are both coaxially disposed with the wheel hub 1, the rim 31 is fixedly sleeved on the wheel hub 1, the rim 32 is divided into multiple segments, two adjacent segments of the rim 32 are movably connected, the connecting rod 33 is located between the rim 31 and the rim 32, two connecting rods 33 are connected between each segment of the rim 32 and the rim 31, two ends of the connecting rod 33 are movably connected with the rim 32 and the rim 31, two output shafts of each bidirectional cylinder 34 are respectively connected to middle portions of the two connecting rods 33, and each connecting rod 33 is foldable at the connection part of the bidirectional air cylinder 34 on each section of the rim 32, referring to fig. 5 and 6, a hole 341 communicated with the closed space 12 is arranged on the first air chamber a of the bidirectional air cylinder 34, the air pressure in the second air chamber B of the bidirectional air cylinder 34 is smaller than the rated air pressure of the tire 2, when the tire burst buffer device 3 is in an unfolded state, the plurality of sections of rims 32 are connected into a ring, and a gap 23 is arranged between the outer surface of the rim 32 and the inner wall of the tire 2.
Referring to fig. 7, before the tire 1 is punctured and when the tire 2 is punctured, the tire burst damping device 3 is in an unfolded state, the output shaft located in the second air chamber B of the bidirectional air cylinder 34 is extended, the connecting rod 33 is unfolded, and the connecting rod 33 drives the rim 32 to be unfolded, when the rim 32 is unfolded, the cross section of the rim 32 is a circular surface, and a gap 23 is formed between the outer surface of the rim 32 and the inner wall of the tire 2.
Referring to fig. 8, before the tire 2 is inflated or before the tire is completely inflated, the flat tire damper 3 is in a folded state, the output shaft located in the second air chamber B of the bidirectional cylinder 34 is contracted, the link 33 is folded, and the rim 34 is folded. After the tire 2 is inflated, the flat tire cushioning device 3 is converted from the folded state to the unfolded state by the bidirectional cylinder 34 and the link 33.
In one implementation, the width of each section of rim 32 can be set to 1/2 that is less than or equal to the width of the tire 31, two adjacent sections of rims 32 are located on different circular surfaces of the tire (i.e., two connecting rods 33 connected to one section of rim 32, and two connecting rods 33 connected to one adjacent section of rim 32 are installed on different circular surfaces of the wheel hub 1), and when the flat tire buffer device is in a folded state, two adjacent sections of rims 32 just contact each other or do not contact each other, so as to ensure that when the flat tire buffer device is in a folded state, two adjacent sections of rims are staggered with each other. In another implementation manner, the widths of the two ends of each section of rim 32 can be set to 1/2 of the rim width, and the two adjacent sections of rims 32 are located on the same circular surface of the hub 1, so as to ensure that the two adjacent sections of rims are staggered when the tire burst buffering device is in the folded state.
Specifically, referring to fig. 5 and 6, the left end of the first air chamber a is provided with a hole 341, which is communicated with the air pressure environment of the enclosed space 12, and the size of the hole 341 is small, which has a limiting effect on the passing speed of the air. For a radial tire, as the normal working air pressure (or rated air pressure) is 2.2-2.5 bar, the second air chamber B can be filled with 0.8-1.0 bar, the output shaft of the bidirectional cylinder 34 presents a contraction state before supplying and assembling, when the bidirectional cylinder 34 is assembled, the high-pressure air in the tire 2 is slowly injected into the first air chamber a through the hole 341 at the left end of the bidirectional cylinder 34, the piston of the bidirectional cylinder 34 slowly moves rightwards and compresses the air in the second air chamber B, when the pressures of the two air chambers in the bidirectional cylinder 34 are equal, the piston stops moving, the output shaft of the bidirectional cylinder 34 in the second air chamber B presents an extension state (see fig. 5), and the output shaft of the bidirectional cylinder 34 pushes the connecting rod 33 to gradually expand (or stand) in the extension process, so that the rim 32 is slowly expanded. Similarly, when the air pressure in the tire 2 becomes zero instantly after the tire burst, the high-pressure air in the first air chamber a leaks slowly through the hole 341, the piston of the bidirectional cylinder 34 moves leftwards slowly under the pushing of the high-pressure air in the second air chamber B, the output shaft in the second air chamber B contracts gradually, the connecting rod 33 is driven to fold (or incline), and finally the rim 32 is restored to the folded state. Because the size of the hole 341 is smaller, the flat tire buffer device 3 returns to the contracted state from the expanded state after the flat tire, a certain time is needed, and the automobile can normally run in the time, so that the buffer effect is achieved. The bidirectional cylinder 34 can automatically perform the bidirectional action of extension or contraction by utilizing the change of gas pressure in the closed space of the tire 2, so that the expansion and the folding of the tire burst buffer device 3 are realized, the realization is simple, and the cost is low.
In the present embodiment, the rigidity of the contact between the outer surface of the rim 31 and the road surface is greater than the rigidity of the contact between the outer surface of the tire 2 and the road surface, so that the rim 31 can provide continuous mechanical vibration to warn the driver and passengers for timely parking and maintenance after the tire 2 bursts.
Preferably, the tire 31 is a segmented structure, each segment of the tire 31 is connected with a connecting rod 33 and a bidirectional cylinder 34, and two adjacent segments are connected through a coupling head 35. The number of the segmented segments can be 2-4, and preferably 3. Because the bead seat and the rim of the hub 1 are larger than the bead of the tire 2, and the gap between the hub 1 and the tire 2 is limited in the installation process, the tire 31 is designed into a segmented structure (namely, the tire burst buffering device 3 is designed into the segmented structure), and the installation can be carried out in a segmented manner, so that the operation is convenient. Specifically, the number of the segments of the rim 31 and the rim 32 may be the same or different, and the segments of the rim 32 and the rim 31 may be on an extension line of the same diameter (i.e., the diameter of a circle centered on the axis of the hub 1) or may not be on an extension line of the same diameter.
For example, referring to fig. 8, the tire 31 is divided into 3 segments, and each segment of the tire 31 is connected with 4 connecting rods 33, 2 bidirectional cylinders 34 and 2 segments of wheel rims 32. The adjacent two sections of tyre 31 are connected through the connecting head 35 to assemble a complete tyre burst buffer device 3.
Specifically, referring to fig. 9, two ends of each segment of the tire 31 are provided with protrusions 311, the protrusions 311 on two adjacent segments of the tire 311 are combined into a dovetail groove structure 351, and the coupling head 35 is a coupling buckle 352 matched with the dovetail groove structure 351. On one hand, the flat tire buffer device 3 works in the narrow closed space 12 between the hub 1 and the tire 2, can rotate at high speed along with the wheel and bear violent vibration from the wheel, and radial force and lateral force applied by the vehicle after the flat tire, so that the requirement on the connection strength is strict; on the other hand, the mounting mode of the flat tire buffer device 3 is simple, the mounting space is small, and the use of tools is not convenient, so that the dovetail groove structure 351 and the connecting buckle 352 matched with the dovetail groove structure are adopted, the connecting strength is ensured, and the convenience of mounting operation is also considered.
In other implementations, the tire 31 may not be a segmented structure, but rather a unitary structure.
In the present embodiment, referring to fig. 1 and 7, the flat tire cushioning device 3 further includes a sensor 36, and the sensor 36 is mounted on the link 33. The sensor 36 is used for collecting the state information of the flat tire buffering device 3, and transmitting the state information to a console instrument panel in a cab through an Electronic Control Unit (ECU) or a running computer (PC), and if the flat tire buffering device 3 is abnormal, continuous alarming can be realized until the abnormality is eliminated, so that the occurrence of safety accidents is further prevented.
In particular, the sensor 36 may be a position sensor, such as an angular displacement sensor. In practical applications, a sensor 36 may be installed on one of the two connecting rods 33 connected to each bidirectional cylinder 34 to acquire the expansion and contraction state of the bidirectional cylinder 34, so as to determine the state information of the flat tire cushioning device 3.
In practice, the rim 31 may be made of a cast aluminum alloy material, and the outer surface of the rim 31 is coated with engineering plastics. The surface of the rim 31 is coated with engineering plastics, so that vibration can be reduced to a certain extent when the rim 31 is in intervention operation after tire burst. Specifically, the engineering plastic may be ABS (Acrylonitrile butadiene styrene copolymers). The rim 32 and the connecting rod 33 may be made of magnesium-aluminum alloy. The wheel rim 32 and the connecting rod 33 are made of magnesium-aluminum alloy, so that the strength can be ensured, the weight can be reduced, and the light weight requirement of the automobile can be ensured.
The working principle of the following flat tire buffer device is briefly introduced as follows:
when the tire 2 is inflated from an inflated state, the bidirectional air cylinder 34 extends to push the connecting rod 33 to slowly expand the rim 31, and a gap 23 is reserved between the outer surface of the rim 31 and the inner surface of the tire 2 after expansion so as to avoid or avoid normal deformation of the tire 2 during running; after the bidirectional cylinder 34 finishes acting, the sensor 36 collects signals and sends the signals to the ECU, and the ECU detects that the signals are safe and are displayed on the instrument;
when the tire 2 is punctured, the tire 2 loses pressure instantly, the tire 2 collapses under the heavy pressure of a vehicle body, the tire burst buffer device 3 supports and maintains the rotation of the wheel, so that safety accidents are avoided, the contact rigidity of the outer surface of the rim 32 and the ground is higher than that of the outer surface of the tire 2 and the ground, and continuous vibration can be generated to remind a driver to stop for overhaul and replace a spare tire; after the high-pressure gas in the bidirectional cylinder 34 leaks through the hole 341 for a period of time, the high-pressure gas gradually contracts and drives the rim 32 to be folded inwards, and the tire burst buffering device 3 is in a folded state, so that the tire 2 is convenient to replace.
According to the embodiment of the invention, the flat tire buffering device is arranged between the tire and the hub, the flat tire buffering device comprises a plurality of sections of rims, the rims can be unfolded and connected into a ring, a gap is formed between the outer surface of each rim and the inner wall of the tire, the normal use of the vacuum tire can be ensured, the vibration of an automobile is effectively slowed down, the comfort level of the automobile is ensured, and the flat tire buffering device in the unfolded state is contacted with the road surface after the tire is flat, so that the flat tire buffering device can replace the tire to enable the automobile to continuously run for a period of time, and the occurrence of traffic accidents caused by flat tire is effectively reduced.
