Detailed Description
Embodiments of the present invention are explained below with reference to the drawings:
as shown in fig. 2 to 5, the present invention discloses a light-duty electric scooter uses the structure of a inflation-free tire, the tire includes a tread portion 1, a tread portion 2, a bead portion 3, a bead portion 4, a plurality of outer arc grooves 32 are circumferentially and equally spaced from the tread portion 2 to the bead portion 3 on both sides of the tire, the outer arc grooves 32 are radially and spirally divergently arranged from being close to the bead portion 4 to the tread portion 2, the width D1 of the outer arc grooves 32 is gradually reduced from the bead portion 4 to the tread portion 2, and the outer arc grooves 32 form tapered surfaces which taper from the tread portion 2, the bead portion 3 and the bead portion 4 to the tread center along the axial direction of the tire; at least one axial inner circular hole 31 is arranged in the outer arc groove 32, namely the outer arc groove 32 is wrapped outside the inner circular hole 31. The inner circular holes 31 may be formed as a plurality of series of inner circular holes 31, and the outer arc grooves 32 are wrapped around the outer side of the series of axial inner circular holes 31.
As shown in fig. 2 and 3, the outer circumferential groove 32 is radially spirally divergently provided from the vicinity of the bead portion 4 toward the shoulder portion 2, and the direction of the spiral coincides with the running direction of the tire as shown by R in fig. 3, and the outer circumferential groove 32 forms an upper tapered surface 32a inclined from the bead portion 2 and the bead portion 3 toward the tread center in the tire axial direction, and a lower tapered surface 32b inclined from the bead portion 4 toward the tread center in the tire axial direction, and the upper tapered surface 32a and the lower tapered surface 32b are inclined from the circumferential rotation direction of the tire running, so that a tapered air shear surface can be formed. When the tire runs, the three-dimensional arc surface formed by circumferential arc, axial cone and radial spiral can be integrally formed by matching with radial spiral divergent arrangement. When the tire runs, the three-dimensional arc-shaped surface can form an air shearing contact surface along the circumferential direction, the axial direction and the radial direction, so that the air shearing force can be gradually extended and dispersed from the tire shoulder part 2 to the tire lip part 4 along the circumferential direction and the radial direction, the energy loss caused by the forward force during the air shearing is reduced, and particularly, the air shearing energy loss caused by the maximum width breaking position A is beneficial to the reduction of the energy consumption of the tire. The included angle alpha 1 between the upper conical surface 32a and the axial direction is 5-15 degrees, when the included angle alpha 1 between the upper conical surface 32a and the axial direction is too small, the effect that the air shearing force gradually extends and disperses from the tire shoulder part 2 to the tire lip part 4 along the circumferential direction and the radial direction is not obvious, and the energy consumption reduction assistance cannot be exerted; if the angle α1 between the upper tapered surface 32a and the axial direction is too large, the contact rigidity of the shoulder portion 2 is too low, and the running stability of the tire cannot be ensured. In addition, the included angle α2 between the lower conical surface 32b and the axial direction is not smaller than the included angle α1 between the upper conical surface 32a and the axial direction, so that the larger included angle α2 between the lower conical surface 32b and the axial direction is formed near the tire lip 4, which is beneficial to the shearing force dispersion requirement of a large amount of air accumulated from the tire shoulder 2 and the tire bead 3, and forms a shearing forward force with smaller bottom, thereby reducing the energy consumption loss of the tire.
The radial inner end 32a and the radial outer end 32b of the outer arc groove 32 are both circular arc edges, so that the air shearing force caused by the circumferential running of the tire can be smoothly transited, and the energy loss can be reduced. Further, a circumferential angle β between a line of the circle center C1 where the circular arc of the radially inner end 32a is located and the circle center C2 where the circular arc of the radially outer end 32b is located and a tangent line in the tire running circumferential direction is 10 ° to 30 °. When the circumferential included angle beta is too small, the space of the three-dimensional arc surface of the outer arc groove 32 is insufficient when the tire runs in the circumferential direction, so that the air shearing force of the shoulder part 2 cannot be well dispersed to the tire lip part 4 with the minimum axial width, and the effect of reducing the energy consumption of the tire is poor; when the circumferential included angle beta is too large, the forward force which is easily dispersed by the circumferential air shearing force of the shoulder part 2 is not obviously reduced, but the energy loss cannot be effectively reduced to improve the low energy consumption effect of the tire.
As shown in fig. 2 and 3, the outer arc groove 32 has a larger width D1 near the tread portion 4, which is beneficial to forming a larger air shear force contact surface near the tread portion 4 with stronger rigidity in the radial direction, and the enlarged width D1 of the outer arc groove 32 can form a three-dimensional arc surface with larger space because of the smaller axial width near the tread portion 4, thereby meeting the shearing force dispersion requirement of a large amount of air accumulated from the tread portion 2 and the tread portion 3, improving the low energy consumption effect of the tire, and ensuring the lower energy consumption effect of the shoulder portion 2 with weaker rigidity when the tire runs near the tread portion 1, and simultaneously maintaining enough rigidity of the shoulder portion 2 and ensuring the running stability. The ratio of the outer width D12 to the inner width D11 of the outer arc groove 32 is 0.5 to 0.8. When the outer width D12 of the outer arc groove 32 is set to be too small, the effective space of the three-dimensional arc surface of the outer arc groove 32 is insufficient, and the energy loss of the tire cannot be reduced to form a low energy consumption effect; when the outer width D12 of the outer arc groove 21 is excessively set, the tire shoulder portion 2 cannot maintain sufficient rigidity, and the tire running stability cannot be ensured. In order to exert the best shearing force dispersing effect of the outer arc groove 32, the ratio of the radial height H1 of the outer arc groove 32 of the tire to the tire section height H is 0.4-0.6, and when the radial height H1 of the outer arc groove 32 is too small, the shearing force dispersing effect of the tire cannot be exerted, and the low energy consumption effect of the tire is influenced; when the radial height H1 of the outer circumferential groove 32 is set too large, the rigidity of the shoulder portion 2 will be affected, and the running stability of the tire will be lowered. The axial cutting width H2 of the outer arc groove 32 at the position of the tire shoulder 2 is 5% -15% of the tire tread width H3, when the axial cutting width H2 of the outer arc groove 32 is too small, the air shearing force of the tire shoulder 2 cannot be well dispersed to the tire lip 4 with the minimum axial width, so that the effect of reducing the tire energy consumption is poor; when the axial cut width H2 of the outer circumferential groove 32 is excessively large, the rigidity of the shoulder portion 2 is excessively weakened, and running stability tends to be lowered.
In addition, the inner round holes 31, 31 'distributed in the outer arc grooves 32, 32' on the two sides of the tire penetrate through the inner part of the whole tire in the axial direction, so that symmetrical contact rigidity can be formed on the two sides of the tire tread, and the rigidity difference on the two sides of the tire tread is more outstanding in response to the vehicle due to wider contact surfaces on the two sides of the center of the tire in running of the vehicle, so that balanced rigidity on the two sides of the tire tread can be provided in running, and the running stability of the tire is ensured. Simultaneously, the outer arc grooves 32 and 32' of the bead parts 3 at the two axial sides are mutually communicated, which is beneficial to the expansion and extension of the outer arc groove 32 and the inner circular hole 31 and ensures the running stability of the tire.
When the tire is mounted on the portable electric vehicle and driven, as shown in fig. 7, if the portable electric vehicle has a tire structure with front and rear axles, the spiral direction of the outer arc grooves 32 on both sides of the bead of the tire is identical to the driving direction R of the tire, so that the outer arc grooves 32 on both sides of the bead can exert an effect of dispersing shearing force during driving of the tire, thereby achieving the purpose of low energy consumption. As shown in fig. 3 and 6, when the lightweight electric vehicle has a tire structure with left and right coaxial surfaces, the spiral directions of the outer sipes 32 and 32 'of the bead portions 3 on both sides of the tire are different from each other, the spiral direction of the outer sipe 32 located on the outer side of the tire mounting matches the running direction R of the tire, and the spiral direction of the outer sipe 32' located on the inner side of the tire mounting may be opposite to the running direction R of the tire. When the tire runs, the air shearing force on the outer side of the installation is larger than that on the inner side of the installation, so that the energy consumption can be reduced by adopting the spiral direction of the outer arc groove 32 consistent with the running direction of the tire on the outer side, and meanwhile, when the spiral directions of the outer arc grooves 32 and 32' of the bead parts 3 on the two sides of the tire are opposite, good air shearing and dispersing effects can be realized when the tire runs forwards or backwards, and the energy consumption of the tire can be reduced.
As shown in fig. 3 and 6, of course, a plurality of inner circular holes 31 are distributed inside the outer arc groove 32, the number of inner circular holes 31 distributed inside the outer arc groove 32 can be set according to the circumferential length of the outer arc groove 32, and the diameter D2 of the inner circular holes 31 is also gradually reduced from the bead portion 4 to the shoulder portion 2, and in this embodiment, the inner circular holes 31 (31') with three apertures are disclosed: large inner circular hole 31a (31 a '), medium inner circular hole 31b (31 b '), small inner circular hole 31c (31 c '). When the spiral directions of the outer arc grooves 32 of the bead portions 3 on both sides of the tire are different from each other, the middle inner circular hole 31b and the small inner circular hole 31c adopt coaxial double-layer stepped holes, namely: the inner circular hole 31b on one side of the tread and the small inner circular hole 31c 'on the other side of the tread adopt coaxial double-layer stepped holes, and the inner circular hole 31c on one side of the tread and the inner circular hole 31b' on the other side of the tread adopt coaxial double-layer stepped holes, so that the same spiral directions on two sides of the tire are formed by utilizing coaxial transformation between the inner circular hole and the small inner circular hole of the tire, and opposite spiral directions of the outer arc groove 32 are formed in the running process of the tire, so that the tire can play a role of low energy consumption in advancing or retreating. The ratio between the diameter D22 of the middle inner circular hole 31b and the diameter D23 of the small inner circular hole 31c is 1.0 to 1.5, and when the difference between the diameter D22 of the middle inner circular hole 31b and the diameter D23 of the small inner circular hole 31c is large, the rigidity difference on both sides of the tread is excessively large during running of the tire, resulting in a decrease in running stability of the tire.
As shown in fig. 8, a separate outer circular hole 33 may be provided between two circumferentially adjacent outer arc grooves 32. The outer circular hole 33 on one side of the tread is axially communicated with the inner circular hole 31b on the other side and the diameters of the two are the same. The outer arc groove 32 on one side of the tread is wrapped on the outer sides of the large inner round hole 31a, the middle inner round hole 31b and the small inner round hole 31c, and the outer round hole 33 is an independent hole; while the outer arc groove 32 on the other side of the tire is wrapped on the outer sides of the large inner circular hole 31a, the outer circular hole 33 and the small inner circular hole 31c, and the middle inner circular hole 31b is an independent hole. The bead portions 3 on both sides can form the outer circumferential grooves 32 in the same spiral direction, and the opposite spiral directions of the outer circumferential grooves 32 are formed during the running of the tire, so that the tire can play a role in low energy consumption during the advancing or retreating.
Various portable electric scooter tires of tire gauge 8X2.00 were made and tested and evaluated for performance using the tire bead construction patterns of fig. 2 and 3. The front wheel and the rear wheel of each test tire are matched with the rim 145X35 and are arranged on the portable electric scooter and run on a paving route, the running stability is respectively evaluated through the sense organs of a driver, and the energy consumption characteristics of the tires are evaluated through the energy consumption reduction rate of the batteries of the vehicles after the test.
The test result can confirm that the low-energy consumption performance of the tire can be improved while the running stability of the tire is ensured after the low-energy consumption inflation-free tire structure is adopted.
The foregoing description is only illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, but rather is intended to cover all modifications and variations in accordance with the present invention.
