Abstract

This invention is related to a roller blade skate wheel, wherein the wheel rim mainly includes a bearing core; a hub for retaining a tire; and a rim for connecting the bearing core and the hub. The rim has a width that is less than that of the hub and the bearing core, and the distance from the hub to the outer surface of the tire reduces from the frontal face towards the opposing lateral sides, such that kinetic energy of the skating can be accumulated and recovered by means of the resilience of the tire, and the resilient deformation of the hub and the rim. Further, when the skate wheel assumes an inclined position, the reducing distance from the hub to the outer surface of the tire increases the frictional coefficient and damping force of the tire so as to increases the frictional force between the tire and the ground so as to prevent from skidding during skating.

V. Description of the invention (3) The core 212 and the bearing core 211 are small and the width a of the tire 22 is greater than the thickness B, and the distance from the core 212 to the outer surface of the tire 22 is from the front to the outside The 'tyre 22' can be made from the thermoplastic material of polyurethane, and different tires 22 have different advantages and disadvantages. The diaplastic material has a higher abrasion resistance than the polymer. Relatively, It also has high damping and energy loss. However, because most of the moving load will not be offset by the damping of the tire 2 2 material, it will return by the elastic effect of the rim 21. The elasticity of the rim 21 The action is concentrated by the rim 213 being distorted by the force distance of F2 and F3, and the fetal core 212 being distorted by the F1 action. Please refer to the third picture for the m-in cross-section of the second picture, and please review the first picture, 'The maximum inclination angle of the inline skate 2 when moving forward is Q (about 60 degrees)' The involute range angle of tire 22 is about 150 degrees), and the normal range angle of tire 22 that can be used is G (about 120 degrees): and the range angles that tire 22 is often used are G1 and G2 ( (All are about ^ degrees), so it usually causes great wear, so it is important to avoid the overload system of the elastic limit here; at the same time, the main cause of wear caused by excessive damping system ^ Therefore, the angle range of G 1 and G 2 should be maintained A small damping value to ensure that the friction force is less than a specific value to avoid heat, wear and moving energy consumption; Gi and G 2 angle pillows occupy 60% of the load time in the sliding of the roller skates, so here The elastic limit property is very important. Please refer to the fourth figure, which is a force diagram (a) of a preferred embodiment of the present invention. When the skate wheel 2 is not inclined, it bears a ground reaction force Rr, which is equal to the weight Fw of the skater. And skater's output Fd;

In the description of the invention (4), the reaction force Rr deforms the tire 22, reducing the volume 14 and increasing the volume 13 while the tire core 212 is deformed toward 16c and 16d, and the rim 213 is directed toward U a Or 16b moves, and the reaction force Rr will change due to uneven ground. It is not a fixed value, but can be a vibration force. Most of the vibration is reliable. The elasticity of the tire is isolated from the human body. The remaining energy is Damping is eliminated. Please refer to the fifth figure, which is a schematic diagram of the force of a preferred embodiment of the present invention (b). When the skates move smoothly, they are usually inclined by 15 degrees (that is, the G2 position in the third figure). Is Fwl vertical to the ground, the weighing force Fpl is perpendicular to the axis of rotation, and the above-mentioned combined force is 1 ^ 1, and 1? 1 * 1 is the reaction > and at the same time, the vertical force of the force Frl and Rrl is Fvl and Rvl, and the horizontal force Rfl represents the minimum frictional force to avoid sliding; it can be seen that, because the magnitude of the frictional force is determined by the vertical force Rv 1 and the friction coefficient of the ground, and the inclination of the skates will reduce the vertical force Rv 1, this embodiment borrows When tilting, the thickness of the outer edge of the tire 2 2 0 that touches the ground is reduced from the thickness of the tire core 2 1 2 compared to when it is vertical, which can reduce the elastic limit 'make the damping' increase to increase the coefficient of friction and ensure that the tire 2 2 0 has sufficient ground Friction force 'to prevent slipping; therefore, the larger the inclination angle of the skate wheel, the smaller the ground vertical force Rvl, and the smaller the thickness of the tire 22 is needed to increase the damping and friction coefficient to ensure that the tire 2 2 (3 and the ground produce Enough friction to prevent slipping However, the damping effect is easy to cause loss of moving energy. Therefore, in the present embodiment, because the width of the wheel flange 2 1 is larger than the tire core 2 1 2 and the bearing core 2 1 1 is / J, 'through the joint force Frl The radial component force Fdl will generate a moment Fdl X al, which causes the rim 2 1 3 to deform toward F 2 or F 3 (as shown in the first figure) and causes w to change. At the same time, the radial of Rr 1 The component force Rd 1 will generate a dynamic moment Rd]

446568 V. Description of the invention (5)-xa2 causes pi core 212 to deform (as shown in the figure), so that the movement energy is stored during the deformation, and the energy is returned by the elastic recovery effect and used as the driving force. Please refer to the sixth figure, which is a schematic diagram of the tire thickness according to a preferred embodiment of the present invention. The distance from the tire core 2 1 2 to the outer surface of the tire 22 decreases from the front to the two outer sides. The indicator line 29 The maximum amount of deformation at the line is 6%, and the elastic ratios at the lines 30 and 30 * are increased to increase the damping and friction. The maximum deformation is 22%, and the elastic ratios at the lines 31 and 3 * are again Increase, the maximum deformation amount is 26%, the maximum deformation amount at the instruction lines 32 and 32 * is increased to 30%, and the maximum deformation amount at the instruction lines 33 and 33 * is increased to 35%: Therefore, 'this embodiment may When the skating wheel 2 is tilted, the thickness of the outer edge of the tire 2 2 0 that touches the ground is reduced from the vertical thickness of the tire core 2 1 2 to increase the damping to increase the coefficient of friction. 'Ensure that the tire 2 2 0 has sufficient friction with the ground To prevent slipping. The impact force from the ground is deformed and absorbed by the elastic tire 22 and the rim 21 in order to ensure the sliding quality and prevent the human body from vibrating. The use of the elastic shape of the tire 22 and the wheel 21 The action restores energy to help move. At the same time, the distance from the tire core 212 to the outer surface of the tire 22 decreases from the front to the two outer sides. When the skate wheel 2 is tilted, the friction of the tire 22 can be changed to increase friction. Coefficient, so that there is sufficient friction between the tire 22 and the ground to prevent the skate wheel 2 from slipping, to achieve the effect of converting the movement energy to avoid slipping. As mentioned above, the inline skating roller of the present invention can effectively convert the moving energy and improve the effect of avoiding skidding. Therefore, the present invention is an improvement
