Description

Technical Field

[0001] This utility model relates to the field of solid tires, specifically a solid tire that is resistant to wet skids and wear. Background Technology

[0002] Solid tires are tire products made of natural rubber, synthetic rubber, and various filler materials through integral vulcanization molding, without an internal air cavity. They rely on the elasticity and structural strength of the rubber itself to bear loads and cushion impacts, avoiding safety hazards caused by air leaks and blowouts. Their manufacturing process typically employs a molding vulcanization process, making the tire carcass dense and wear-resistant. They are suitable for low-speed, heavy-duty vehicles such as forklifts, mining machinery, and port machinery, exhibiting excellent wear resistance, puncture resistance, tear resistance, and maintenance-free advantages under harsh working conditions. At the same time, the structural design of solid tires generally consists of a hard load-bearing layer, a flexible buffer layer, and a wear-resistant tread layer, ensuring both load-bearing capacity and a certain degree of comfort and service life.

[0003] Existing solid tires typically use a single solid rubber filler to ensure wear resistance and strength, but only consider wear resistance and strength while neglecting comfort and cushioning performance, resulting in poor riding or driving comfort and weak impact resistance and shock absorption. In addition, the single solid structure has defects in terms of sidewall damage resistance, wheel hub fit and thermal expansion adaptation, which can easily lead to separation, sidewall damage or insufficient puncture resistance, thus limiting its practicality. Based on this, this utility model designs a solid tire that is anti-slip and wear-resistant to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a solid tire that is resistant to wet skids and wear, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A solid tire that is resistant to wet skids and wear includes a supporting hub, with a rigid frame mechanism and a composite buffer mechanism sequentially arranged on the outer side of the supporting hub. The rigid frame mechanism includes multiple sets of support rods fixed to the outer wall of the supporting hub, a ring-shaped steel bar located at the distal end of the support rods, a first rubber layer covering the outer side of the ring-shaped steel bar, and first side reinforcing ribs fixed on both sides of the first rubber layer. The composite buffer mechanism includes a second rubber layer sleeved on the outer side of the first rubber layer, a ring-shaped mounting groove opened in the second rubber layer, and a honeycomb frame filled in the mounting groove and forming a ring structure along the circumference. A second side reinforcing rib is fixedly installed at the left end of the second rubber layer, a third side reinforcing rib is fixedly installed at the right end of the second rubber layer, and an anti-skid tread is fixedly provided on the outer wall of the second rubber layer.

[0006] Optionally, the multiple sets of support rods are circumferentially encircled and evenly distributed on the outer wall of the support hub, and the annular steel bars are connected by the far ends of each support rod to form a continuous ring.

[0007] Optionally, after the first rubber layer covers the annular steel bar, the first side reinforcing bars are fixed on its left and right sides respectively. The first side reinforcing bars extend in a circumferential direction and are fixedly connected to the first rubber layer.

[0008] Optionally, the mounting groove is a continuous annular groove in the circumferential direction, and the honeycomb frame is filled in the annular groove to form a continuous buffer structure in the circumferential direction.

[0009] Optionally, the second side reinforcing rib is fixed to the inner left end of the second rubber layer, and the third side reinforcing rib is fixed to the inner right end of the second rubber layer. Both are arranged in a ring shape to strengthen the sidewall.

[0010] Optionally, the anti-slip tread is fixed to the outer wall of the second rubber layer, and anti-slip grooves are distributed on the outer wall of the anti-slip tread. The anti-slip grooves on the outer wall of the anti-slip tread are distributed along the anti-slip tread to form an external anti-slip texture.

[0011] Optionally, the honeycomb frame is formed by multiple sets of honeycomb units arranged circumferentially to form a ring frame, and the honeycomb frame is fixed in place with the mounting groove to form a circumferential buffer layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, a rigid frame mechanism is provided, and the support rod and the ring steel bar form a circumferentially continuous reinforced support ring on the outer wall of the support hub, so that the first rubber layer and the first side reinforcement ribs on both sides are uniformly loaded and constrained under radial and lateral loads, thereby improving the overall structural stability and optimizing the fit with the support hub.

[0013] 2. In this utility model, a composite buffer mechanism is provided. The second rubber layer, the annular mounting groove and the honeycomb frame filled therein work together to disperse the impact of the outer layer in the circumferential direction and provide controllable buffering. It also works with the anti-slip tread on the outer wall to take into account comfort, puncture resistance and grip performance on wet and slippery roads. Attached Figure Description

The support rod 201 is fixed to the outer wall of the support hub 1, and its far ends are connected to form a ring-shaped steel bar 202; The outer side of the ring-shaped steel bar 202 is covered with a first rubber layer 203, and after the covering, the first rubber layer 203 is fixed with first side reinforcing bars 204 on its left and right sides. The second rubber layer 301 is sleeved on the outside of the first rubber layer 203. An installation groove 302 is opened in the second rubber layer 301 along the circumferential direction. A honeycomb frame 303 is filled in the installation groove 302, and the honeycomb frame 303 is fixed in conjunction with the installation groove 302. The second rubber layer 301 has a second side reinforcing rib 304 fixed to the left inner side and a third side reinforcing rib 305 fixed to the right inner side.

Example 1 This embodiment of the solid tire includes a supporting hub 1, a rigid frame mechanism 2, and a composite buffer mechanism 3. The rigid frame mechanism 2 is located outside the supporting hub 1, and the composite buffer mechanism 3 is sleeved on the outside of the rigid frame mechanism 2 and distributed concentrically around it. During assembly, several support rods 201 are first fixed circumferentially to the outer wall of the supporting hub 1. The ends of the support rods 201 away from the supporting hub 1 are connected to each other to form a ring-shaped steel bar 202. Then, the outer side of the ring-shaped steel bar 202 is covered with a first rubber layer 203, followed by the first rubber layer 203... First side reinforcing ribs 204 are fixed on the left and right sides of 03. Finally, the second rubber layer 301 is sleeved on the outside of the first rubber layer 203. A ring-shaped mounting groove 302 is opened in the circumferential direction inside the second rubber layer 301, and the honeycomb frame 303 is filled in the mounting groove 302. The second side reinforcing rib 304 is fixedly installed on the inner side of the left end of the second rubber layer 301, and the third side reinforcing rib 305 is fixedly installed on the inner side of the right end. An anti-slip tread 306 is fixed on the outer wall of the second rubber layer 301, and an anti-slip groove is provided on the anti-slip tread 306. Specific implementation of rigid frame mechanism 2 in Example 2 The rigid frame mechanism 2 consists of several support rods 201 fixed to the outer wall of the supporting hub 1 and a ring-shaped steel bar 202 formed by connecting the distal ends of each support rod 201. The support rods 201 are circumferentially encircled and fixed to the outer wall of the supporting hub 1, so that the rigid frame mechanism 2 and the supporting hub 1 form an integrated support relationship. The outer side of the ring-shaped steel bar 202 is covered with a first rubber layer 203. The first rubber layer 203 is fixedly connected to the first side reinforcing ribs 204 on its left and right sides, respectively. The first side reinforcing ribs 204 extend circumferentially and are fixedly connected to the first rubber layer 203. In this structure, the support rods 201 and the ring-shaped steel bar 202 form a circumferentially continuous rigid frame. The rigid or semi-rigid support ring has a first rubber layer 203 forming a transition layer between the outer layer and the inner frame by covering the ring steel bar 202. The first side reinforcement rib 204 further enhances the lateral restraint capacity of the side wall on both sides of the first rubber layer 203. Specifically, the support rod 201 is equidistantly distributed and fixed along the outer wall of the support hub 1. The far end of the support rod 201 is connected to the ring steel bar 202. The ring steel bar 202 is covered by the first rubber layer 203 on the outside. The left and right ends of the first rubber layer 203 are respectively connected to the first side reinforcement rib 204 to ensure the overall coordinated bearing capacity of the rigid frame mechanism 2 under radial load and lateral load. Specific implementation of composite buffer mechanism 3 in Example 3 The composite buffer mechanism 3 consists of a second rubber layer 301 sleeved on the outside of the first rubber layer 203, an annular mounting groove 302 formed in the second rubber layer 301, a honeycomb frame 303 filled in the mounting groove 302 and forming an annular structure along the circumference, a second side reinforcing rib 304, a third side reinforcing rib 305, and an anti-skid tread 306 fixed to the outer wall of the second rubber layer 301. Specifically, the second rubber layer 301 is sleeved on the outer surface of the first rubber layer 203, and the second rubber layer 301 has a continuous annular mounting groove 302 pre-reserved and formed along the circumference on the inner side of its thickness. The honeycomb frame 303 is arranged with multiple honeycomb units along the circumference and filled with... The honeycomb frame 303 is fixedly connected to the mounting groove 302 within the annular mounting groove 302 to form a continuous circumferential buffer layer. The second side reinforcing rib 304 is fixedly connected to the inner left end of the second rubber layer 301, and the third side reinforcing rib 305 is fixedly connected to the inner right end of the second rubber layer 301. Both are arranged in annular shape and are fixedly connected to the second rubber layer 301. The anti-skid tread 306 is fixed to the outer wall of the second rubber layer 301 and has anti-skid grooves distributed on its surface. The composite buffer mechanism 3 is structurally a system in which the outer anti-skid tread 306, the second rubber layer 301, the annular mounting groove 302 / honeycomb frame 303 and the inner rigid skeleton mechanism 2 are coupled layer by layer. Example 4 In this embodiment, the anti-skid tread 306 is in direct contact with the road surface, and its anti-skid grooves are distributed on the outer surface of the anti-skid tread 306 to enhance the ground friction and drainage capacity of the wet road surface. When an external load is applied to the anti-skid tread 306, the load is transmitted through the second rubber layer 301 to the mounting groove 302 and the honeycomb frame 303 therein. The honeycomb frame 303 distributes the force in the circumferential direction and cooperates with the mounting groove 302 to constrain it, thereby forming a continuous circumferential buffer zone on the outer layer. The buffer zone transmits the stress to each other through the first rubber layer 203 and the ring steel bar 202. The ring steel bar 202 transfers the load to the support hub 1 through each support rod 201. The first side reinforcement rib 204, the second side reinforcement rib 304 and the third side reinforcement rib 305 are respectively fixed on the side of the corresponding rubber layer to constrain the side wall under lateral load or thermal expansion and optimize the cooperation with the support hub 1 to prevent the side wall from detaching or slipping. Example 5 In this embodiment, the rigid frame mechanism 2 serves as the inner rigid or semi-rigid support unit, with key components being the support rod 201 and the annular steel bar 202. The support rod 201 is fixed to the outer wall of the support hub 1 to ensure the stability of the annular steel bar 202. The first rubber layer 203 covers the annular steel bar 202 and is connected to the first side reinforcement 204 to increase lateral strength. The composite buffer mechanism 3 is centered on the second rubber layer 301 and the honeycomb frame 303 in the annular mounting groove 302. The honeycomb frame 303 is arranged circumferentially and filled in the mounting groove 302 to form a continuous buffer layer. The anti-skid tread 306 and the anti-skid groove on its outer wall together meet the grip and drainage requirements of wet and slippery road surfaces. The second side reinforcement 304 and the third side reinforcement 305 are located at the inner left and inner right ends of the second rubber layer 301, respectively, to strengthen lateral restraint and work with the first side reinforcement 204 to form multi-layer sidewall protection.
