Description

Technical Field

[0001] The utility model belongs to the technical field of automobile tires, and particularly relates to a tire with a detachable tread and a car comprising the tire. Background Art

[0002] Automobile tires are mainly made of materials such as rubber, steel wire, nylon and chemical additives. The processing of waste automobile tires will inevitably cause environmental pollution. The more the processing volume, the more serious the pollution. Common automobile tires are equipped with a carcass connected to the wheel hub. The carcass is composed of an inner tube and an outer tube, or only an outer tube. However, no matter how the tire structure changes, its outer circumferential surface cannot be disassembled, so once the outer circumferential surface of the tire is worn, it must be replaced and scrapped together with the two axial end surfaces. Scrapping the unworn axial end surface of the tire together with the worn circumferential surface increases the cost of automobile raw materials, and also causes a waste of rubber resources and increases waste emissions.

[0003] The prior art solves the resource waste problem caused by scrapping the unworn axial end face of the tire together with the worn circumferential surface by separating the tread from the carcass. Specifically, the position of the tread along the rotation direction of the tire is restricted by matching the convex strips on the inner surface of the tread with the grooves on the outer surface of the carcass. For example, the patent with publication number CN102139604A discloses a car tire with a detachable wear surface, in which a plurality of grooves inclined to the axis and evenly distributed on the circumferential surface are provided on the outer circumferential surface of the carcass, and a plurality of convex strips matching the grooves are provided on the inner surface of the tread. The grooves and the convex strips cooperate to connect the carcass with the tread, thereby restricting the tread from sliding along the rotation direction of the tire. However, the above scheme requires the tread to be expanded and then put on the carcass, which is difficult to operate and inconvenient to install. Utility Model Content

[0004] The utility model aims to solve the problem that the detachable tire tread in the prior art needs to be expanded before it can be taken off the tire body or put on the tire body, which causes difficulty in operation and inconvenience in installation.

[0005] In order to solve the above technical problems, the utility model discloses a tire, comprising a carcass and a tread, wherein the tread is sleeved on the outer peripheral surface of the carcass, and the tire further comprises a fixing assembly, wherein the fixing assembly comprises a first blocking portion and a second blocking portion; the first blocking portion is connected to and relatively fixed with the first end of the carcass, and abuts against the first end surface of the tread, the second blocking portion is connected to and relatively fixed with the second end of the carcass, and abuts against the second end surface of the tread, at least one of the first blocking portion and the second blocking portion is detachably connected to the carcass, and in the radial direction of the tire, the outer peripheral surface of the tread protrudes from the first blocking portion and the second blocking portion. In the axial direction of the tire, the first end of the carcass is disposed opposite to the second end, and the first end surface of the tread is disposed opposite to the second end surface.

[0006] The above technical solution is adopted, and the tire includes a carcass and a tread. The tread is sleeved on the outer peripheral surface of the carcass. The main function of the carcass is to buffer and bear weight, and the outer peripheral surface of the tread away from the carcass is a wear surface in contact with the ground. The tire also includes a fixing assembly, and the fixing assembly includes a first blocking portion and a second blocking portion. The two blocking portions are respectively connected to the two ends of the carcass that are mutually opposed in the axial direction of the tire and are relatively fixed, and the two blocking portions are also respectively correspondingly abutted with the end surfaces of the two ends of the tread that are mutually opposed in the axial direction of the tire, so that a spacing area is formed between the first blocking portion and the second blocking portion, and the tread is clamped in the spacing area formed by the first blocking portion and the second blocking portion. Each blocking portion abuts against the end surface corresponding to the tread to prevent the tread from sliding to both sides of the axial direction of the tire. In addition, in the radial direction of the tire, the outer peripheral surface of the tread protrudes from the first blocking portion and the second blocking portion, so that the tread protrudes from the blocking portion and does not hinder the tread from contacting the ground and rotating.

[0007] At least one of the first blocking part and the second blocking part is detachably connected to the tire body. Therefore, when the tread is severely worn and needs to be replaced, at least one blocking part is removed and the tread can be easily removed along the axial direction of the tire. The new tread is sleeved on the outer peripheral surface of the tire body in the same way, and finally the blocking part is installed to complete the replacement. Compared with the prior art, this process does not require expansion of the tread when installing or removing the tread, and has the beneficial effects of simple operation and convenient installation.

When the blocking ring is fixedly connected to the carcass, the blocking ring acts as a limiting device to prevent the tread from separating from the carcass along the axial direction of the tire.

[0012] According to another specific embodiment of the utility model, in the tire disclosed in the embodiment of the utility model, each retaining ring is provided with a plurality of through holes arranged at intervals along its circumference, and a corresponding end of the tire body is provided with a plurality of threaded holes matching the plurality of through holes, and a fastener is inserted through each through hole in the plurality of through holes and the corresponding threaded hole, so that the retaining ring is threadedly connected to the tire body.

[0013] By adopting the above technical solution, each retaining ring is fixed to the carcass by using a plurality of fasteners. After each fastener passes through a corresponding through hole and fits into a threaded hole of the carcass, a detachable fixed connection can be achieved.

[0014] According to another specific embodiment of the utility model, in the tire disclosed in the embodiment of the utility model, one of the first blocking part and the second blocking part is configured as a blocking ring; and the other blocking part is configured as: a flange protruding from the outer peripheral surface of the tire body.

[0015] By adopting the above technical scheme, the blocking part and the flange of the retaining ring both protrude from the outer peripheral surface of the tire body, and abut against the first end face and the second end face of the tread, which can play a limiting role. The connecting part of the retaining ring can also be removed from the tire body, which is convenient for replacing the worn tread. The flange is directly fixedly connected to the outer peripheral surface of the tire body to block and fix the second end face of the tread. This setting method can not only meet the disassembly requirements of the retaining ring, but also has the advantages of simple structure and cost saving.

[0016] According to another specific embodiment of the utility model, the tire disclosed in the embodiment of the utility model has a plurality of snap structures arranged at intervals in the circumferential direction of the tire, which are snapped together by the plurality of snap structures so that the tread and the carcass are relatively fixed in the circumferential direction of the tire; wherein each of the plurality of snap structures includes a snap and a slot that are snapped together with each other, one of the snap and the slot is arranged on the inner circumferential surface of the tread, and the other is arranged on the outer circumferential surface of the carcass, and the snap and the slot both extend along the axial direction of the tire, and are arranged so as to be pluggable with each other from at least one end of the carcass, wherein the one end of the carcass is the end that is detachably connected to the blocking portion.

[0017] By adopting the above technical scheme, the tread and the carcass can be relatively fixed by means of the snap connection of the snap structure's snap connection and the snap groove, preventing the tread from sliding relative to the carcass along the circumference of the tire, and the snap structure and the snap groove are inserted into each other at one end where the carcass and the blocking portion are detachably connected and extend along the axial direction of the tire, making it easy to remove the tread from the end where the carcass and the blocking portion are detachably connected along the axial direction of the tire, thereby facilitating replacement of the tread.

[0036] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] In the prior art, when the detachable tire tread is disassembled and installed, the tread needs to be expanded so that it can be removed from the tire body or put on the tire body, which has the problems of difficult operation and inconvenient installation.

[0038] Example 1

[0039] In view of the above problems, the utility model provides a tire, such as Figure 1-Figure 3 As shown, it includes a carcass 10 and a tread 20. The tread 20 is sleeved on the outer peripheral surface of the carcass 10. The carcass 10 mainly functions as a buffer and load-bearing device. The outer peripheral surface of the tread 20 away from the carcass 10 is a wear surface in contact with the ground. Figure 1 and Figure 2 As shown, the tire further includes a fixing assembly 30, which includes a first blocking portion 300 and a second blocking portion 310; the first blocking portion 300 is connected to and relatively fixed with the first end 100 of the carcass 10, and abuts against the first end face 200 of the tread 20, and the second blocking portion 310 is connected to and relatively fixed with the second end 101 of the carcass 10, and abuts against the second end face 201 of the tread 20, in the axial direction ( Figure 2 In the X direction), the first end 100 and the second end 101 of the tire body 10 are arranged opposite to each other, and the first end face 200 and the second end face 201 of the tread 20 are arranged opposite to each other, so that a spacing area is formed between the first blocking portion 300 and the second blocking portion 310. The tread 20 is clamped in the spacing area formed by the first blocking portion 300 and the second blocking portion 310, and each blocking portion abuts against the end face corresponding to the tread 20 to prevent the tread 20 from moving in the axial direction ( Figure 2 The tire body 10 is slid away from both sides of the tire body 10 (in the X direction).

[0040] Specifically, in this embodiment, Figure 2 As shown, in the radial direction of the tire ( Figure 1-Figure 3 In the Y direction), the outer circumference of the tread 20 protrudes from the first blocking portion 300 and the second blocking portion 310, that is, the radius of the tread 20 is larger than the radius of the first blocking portion 300 and the second blocking portion 310, so that the outer circumference of the tread 20 protrudes from the outer circumference of the blocking portion, so that the tread 20 contacts the ground and rotates when the tire is in use. The radius of each blocking portion is larger than the radius of the carcass 10 and smaller than the radius of the tread 20, and the blocking portion only limits the first end face 200 and the second end face 201 of the tread 20. At least one of the first blocking portion 300 and the second blocking portion 310 is detachably connected to the carcass 10, so that when the tread 20 is severely worn and needs to be replaced, at least one blocking portion is removed from the carcass 10, and the tread 20 can be moved along the axial direction ( Figure 2The tire body 10 is easily removed by sliding the new tread 20 onto the outer circumference of the tire body 10 in the same way, and the blocking part is finally installed to complete the replacement. Compared with the prior art, this process does not require the expansion of the tread 20 when installing or removing the tread 20, and has the beneficial effects of simple operation and convenient installation. It should be noted that the detachable connection method can be a threaded connection, a pin connection, a snap connection, etc., and there is no specific limitation here, as long as at least one blocking part can be fixed to the tire body 10 and is easy to disassemble.

[0041] It should be noted that the connection between the tread 20 and the carcass 10 can be directly sleeved together, bonded by colloid, snapped together by a matching buckle structure, etc., as long as the tread 20 and the carcass 10 can be detachably connected, and the tread 20 should not be along the circumferential direction of the tire ( Figure 1 and Figure 3 The first blocking portion 300 and / or the second blocking portion 310 may be annular or may be shaped along the radial direction (Z direction) of the tire. Figure 1-Figure 3 A plurality of flanges arranged at intervals (in the Y direction) protruding from the outer circumferential surface of the tire body 10 can be used as long as they can limit the first end face 200 and the second end face 201 of the tread 20.

[0042] In one embodiment of the present invention, each of the first blocking portion 300 and the second blocking portion 310 is annular. Figure 1 As shown, the annular blocking portion ( Figure 1 The shape of only the first blocking portion 300 is shown in the figure, and matches the shape of the tread 20 and the carcass 10, so that the entirety of the two blocking portions is in contact with the carcass 10, and the two blocking portions are completely in contact with the first end face 200 and the second end face 201 of the tread 20 along the circumferential direction of the ring, so that the tread 20 is completely limited on the carcass 10, and the tread 20 is more stably prevented from moving in the axial direction of the tire ( Figure 2 The tire body 10 is slid away from both sides of the tire body 10 (in the X direction).

[0043] In one embodiment of the present invention, at least one of the first blocking portion 300 and the second blocking portion 310 is configured as an annular blocking ring. Figure 1 As shown, the first blocking portion 300 is an annular blocking ring, which includes a Figure 1-Figure 3 The connecting portion 301 and the blocking portion 302 are sequentially connected from the inside to the outside (in the Y direction). The connecting portion 301 is attached to the end surface corresponding to the end of the tire body 10 and is detachably fixedly connected to the corresponding end of the tire body 10. The blocking portion 302 abuts against the corresponding end surface of the tread 20. When the blocking ring is fixedly connected to the tire body 10, the blocking portion of the blocking ring acts as a limiting device to prevent the tread 20 from moving along the axial direction ( Figure 2 The tire body 10 is separated from the tire body 10 by the X direction.

[0044] It should be noted that the first blocking portion 300 and the second blocking portion 310 can be both set as annular blocking rings, and the connecting portion 301 of each blocking ring is detachably fixedly connected to the first end 100 and the second end 101 opposite to the carcass 10, respectively, and the blocking portion 302 of each blocking ring is respectively fitted to the first end face 200 and the second end face 201 opposite to the tread 20. When the tread 20 needs to be replaced, those skilled in the art can remove any blocking ring as needed to replace the tread 20. It can be understood that in this embodiment, the blocking ring can be made of metal, high-strength rubber or carbon fiber composite materials, etc., as long as it has sufficient strength to meet the function of blocking the tread 20.

[0045] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, each retaining ring is provided with a plurality of through holes 303 arranged at intervals along its circumference, and a plurality of threaded holes 102 matching the plurality of through holes 303 are provided at the corresponding end of the carcass 10, and a fastener 320 (i.e., a bolt) is inserted into each through hole 303 and the corresponding threaded hole 102 in the plurality of through holes 303, so that the retaining ring is threadedly connected with the carcass 10. Each retaining ring is fixed to the carcass 10 by using a plurality of fasteners 320, and each fastener 320 is adapted to the threaded hole 102 of the carcass 10 after passing through the corresponding through hole 303, so that a detachable fixed connection can be achieved. It can be understood that in order to make the fixing force of the fastener 320 on the retaining ring more uniform, the plurality of through holes 303 of the retaining ring are uniformly and spaced along its circumference, and the plurality of threaded holes 102 matching the plurality of through holes 303 opened at the corresponding end of the corresponding carcass 10 are also uniformly and spaced along the circumference of the carcass 10.

[0046] In one embodiment of the present invention, one of the first blocking portion and the second blocking portion is configured as a blocking ring; the other blocking portion is configured as a flange protruding from the outer peripheral surface of the tire body 10. Figure 2 As shown, the first blocking portion 300 is configured as a blocking ring, and the second blocking portion 310 is configured as a flange.

[0047] Specifically, in this embodiment, Figure 2As shown, the connecting portion 301 of the retaining ring is detachably fixedly connected to the first end 100 of the carcass 10, and the blocking portion 302 of the retaining ring abuts against the first end face 200 of the tread 20. The flange is formed at the position of the carcass 10 away from the first end 100, that is, the second end 101. The flange is arranged to protrude from the outer peripheral surface of the carcass 10 and abut against the second end face 201 away from the first end face 200 of the tread 20. The blocking portion 302 and the flange of the retaining ring can both play a role in limiting the tread 20. The connecting portion 301 of the first blocking portion 300 (retaining ring) can also be removed from the carcass 10 to facilitate the replacement of the worn tread 20. The manner in which the connecting portion 301 of the retaining ring is detachably fixedly connected to the first end 100 of the carcass 10 can be specifically threaded connection, pin connection, snap connection, etc., which is not specifically limited here, as long as the retaining ring can be fixed to the carcass 10 and is easy to remove. The flange is directly fixedly connected to the outer circumference of the tire body 10 to block and fix the second end face 201 of the tread 20. Such a setting method can not only meet the removal requirements of the retaining ring, but also has the advantages of simple structure and cost saving. The second blocking portion 310 (flange) and the tire body 10 can be integrally formed, or fixedly connected together by bonding, clamping, etc., as long as it can be fixed to the outer circumference of the tire body 10 and abut against the second end face 201 of the tread 20.

[0048] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the circumferential direction of the tire ( Figure 3 A plurality of buckle structures are arranged at intervals in the Z direction of the tire, and the tread 20 and the carcass 10 are connected by the buckle structures so that the tread 20 and the carcass 10 are connected in the circumferential direction of the tire ( Figure 3 Each of the multiple buckle structures includes a buckle 203 and a slot 103 that are engaged with each other. One of the buckle 203 and the slot 103 is disposed on the inner circumference of the tread 20, and the other is disposed on the outer circumference of the carcass 10. The buckle 203 and the slot 103 are both disposed along the axial direction ( Figure 2 The buckle 203 extends in the axial direction of the tire ( Figure 2 The slot 103 is a strip-shaped protrusion extending in the axial direction ( Figure 2 The strip-shaped groove 203 and the slot 103 are arranged to be plugged into each other at least from one end of the tire body 10, wherein the end of the tire body 10 is the end that is detachably connected to the blocking portion. It should be noted that the cross-sectional shapes of the strip-shaped buckle 203 and the slot 103 can be rectangular, U-shaped, trapezoidal, wedge-shaped, etc., as long as they can be mutually adapted and engaged to prevent the tread 20 from moving along the circumferential direction ( Figure 3 Just slide in the Z direction.

[0049] Specifically, in this embodiment, Figure 2 As shown, the tread 20 and the carcass 10 can be relatively fixed by the buckle 203 of the buckle structure and the buckle slot 103, which can prevent the tread 20 from moving along the circumference of the tire ( Figure 3 The buckle 203 and the slot 103 of the buckle structure are both along the axial direction (Z direction) of the tire. Figure 2 X direction), and as Figure 3 As shown, the buckle 203 and the slot 103 are plugged into each other from the first end 100 of the carcass 10, so that the buckle structure clamps the tread 20 to the carcass 10, making it easy to move the tread 20 from the end of the carcass 10 that is detachably connected to the blocking portion along the axial direction of the tire ( Figure 2 The circumferential direction of the tire ( Figure 3 A plurality of buckle structures are arranged at intervals in the Z direction, one of the buckle 203 and the slot 103 is arranged on the inner circumference of the tread 20, and the other is arranged on the outer circumference of the carcass 10, such as Figure 3 As shown, the buckles 203 of the multiple buckle structures are arranged along the circumference of the tire ( Figure 3 The plurality of snap-fit ​​structure slots 103 are evenly spaced and arranged on the inner circumference of the tread 20 along the circumference of the tire (Z direction). Figure 3 The inner circumference of the tread 20 and the outer circumference of the carcass 10 are evenly spaced apart along the circumferential direction (Z direction) of the tire. Figure 3 The buckles 203 and the slots 103 evenly spaced (in the Z direction) are adapted to be connected so that the interaction force between the tread 20 and the carcass 10 is evenly distributed along the circumferential direction, thereby ensuring that the fixed connection between the tread 20 and the carcass 10 is more stable.

[0050] It should be noted that when the tread 20 and the carcass 10 are connected in the circumferential direction of the tire ( Figure 3 When a plurality of buckle structures spaced apart in the Z direction (in the Z direction) are engaged, the buckle 203 of the buckle structure and the buckle groove 103 are engaged with each other so that the tread 20 and the carcass 10 are spaced apart in the circumferential direction (in the Z direction) of the tire. Figure 3 When the worn tread 20 of the tire needs to be replaced, the retaining ring is removed from the carcass 10. Since the buckle 203 and the slot 103 of the buckle structure are both along the axial direction ( Figure 2 The tread 20 extends in the axial direction of the tire (in the X direction) and is plugged into each other from the first end 100 of the carcass 10. Figure 2The tread 20 can be easily removed from the first end 100 of the carcass 10 by the same method, and the new tread 20 is sleeved on the outer peripheral surface of the carcass 10 from the first end 100. The buckles 203 of the new tread 20 are correspondingly plugged into the slots 103 until the second end face 201 of the tread 20 abuts against the flange of the second end 101 of the carcass 10. Finally, the retaining ring is installed and the fastener 320 is installed to complete the replacement action, which has the beneficial effects of simple operation and convenient installation.

[0051] In one embodiment of the present invention, Figure 3 As shown, the cross-sections of each buckle 203 and the corresponding slot 103 are both trapezoidal, and the bottom of the slot 103 is the lower bottom of the trapezoid.

[0052] Specifically, in this embodiment, Figure 3 As shown, when the buckle 203 is moved along the circumference of the tire ( Figure 3 The plurality of snap-fit ​​structure slots 103 are evenly spaced and arranged on the inner circumference of the tread 20 along the circumference of the tire (Z direction). Figure 3 When the clamping groove 103 is evenly spaced on the outer peripheral surface of the carcass 10 (in the Z direction), the bottom of the clamping groove 103 is the lower bottom of a trapezoid, and the notch corresponds to the upper bottom of the trapezoid, so that the cross-sectional shape of the buckle 203 is a trapezoid that is congruent with the cross-sectional trapezoid of the clamping groove 103. Since the lower bottom side length of the trapezoid is greater than the upper bottom side length in the two-dimensional cross section, the area of ​​the bottom of the clamping groove 103 corresponding to the three-dimensional space is greater than the area at the notch opening. Accordingly, the end surface area of ​​the end of the buckle 203 away from the inner peripheral surface of the tread 20 is greater than the end surface area of ​​the other end connected to the tread 20. The hypotenuse of the clamping groove 103 limits the hypotenuse of the buckle 203, further strengthening the fixed connection between the tread 20 and the carcass 10.

[0053] In one embodiment of the present invention, Figure 3 As shown, when a plurality of threaded holes 102 are provided at the corresponding ends of the tire body 10, a plurality of slots 103 and the plurality of threaded holes 102 are staggered along the circumferential direction of the tire, the plurality of threaded holes 102 are used to fix the retaining ring and the tire body 10, and the plurality of slots 103 are used to connect the tread 20 and the tire body 10. Therefore, the plurality of slots 103 and the plurality of threaded holes 102 are matched in number and staggered along the circumferential direction of the tire, so that the connection between the retaining ring, the tread 20 and the tire body 10 can be more stable and firm.

[0054] It should be noted that when multiple slots 103 and multiple threaded holes 102 are staggered along the circumferential direction of the tire, the number of slots 103 and threaded holes 102 along the circumferential direction of the tire are consistent, and the number of both is preferably 16-24. Within this range, the retaining ring and the tread 20 can be fixed to the tire body 10, and the number is moderate, saving parts costs.
