Description

Technical Field

[0001] The utility model belongs to the technical field of tire manufacturing, and particularly relates to a self-cleaning tire structure and a self-cleaning tire assembly. Background Art

[0002] Automobile tires are one of the important parts of an automobile. They are in direct contact with the road surface and work together with the automobile suspension to mitigate the impact of the car when it is driving, ensuring good ride comfort and driving smoothness, ensuring good adhesion between the wheels and the road surface, improving the car's traction, braking and passability, and bearing the weight of the car. The important role that tires play in automobiles is receiving more and more attention.

[0003] Once mud adheres to the tread of a conventional vehicle tire, the centrifugal force generated by its high-speed rotation can be used to throw the mud out. However, agricultural vehicles have a large weight and work in farmland at a slow speed, so it is difficult to provide a large centrifugal force to throw the mud out of the tire tread. As a result, too much mud is easily embedded in the tire tread of agricultural vehicles, affecting the anti-skid effect of the tire tread. Utility Model Content

[0004] The utility model aims to provide a self-cleaning tire structure and a self-cleaning tire assembly to solve the problem that mud in the tire pattern of agricultural vehicles in the above-mentioned background technology is difficult to clean.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A self-cleaning tire structure and a self-cleaning tire assembly, comprising: a crown, a shoulder, a sidewall, a first oblique groove, and a second oblique groove; the crown, the shoulder, and the sidewall constitute the tire, the crown is the ground contact friction surface of the tire, the sidewall is the annular side surface of the tire, the shoulder is the transition area between the crown and the shoulder, the crown has a circumferential array with a first oblique groove and a second oblique groove for anti-skid effect, both the first oblique groove and the second oblique groove are grooves that are inclined downward from the middle of the crown to the sidewall, the width of the first oblique groove and the second oblique groove is greater than or equal to 40 mm, the first oblique groove is inclined downward from right to left, and the second oblique groove is inclined downward from left to right, and the first oblique groove and the second oblique groove are provided with a temporary storage cavity with a pit structure at one end close to the middle of the crown.

[0007] Furthermore, in order to facilitate the mud discharge operation of the first oblique groove and the second oblique groove, the second oblique groove and the first oblique groove have the same structure except for the direction, and the first oblique groove is provided with a notch on the shoulder side to form a shoulder side mud discharge port.

[0008] Furthermore, in order to avoid obstruction of mud discharge, the groove depth of the first oblique groove away from the mud discharge port is greater than the groove depth of the first oblique groove close to the mud discharge port; the upper and lower walls of the first oblique groove are respectively an upper oblique wall and a lower oblique wall; the lower oblique wall and the upper oblique wall are arranged parallel to each other.

[0009] Furthermore, in order to facilitate the rapid separation of mud and dirt in the temporary storage chamber under the action of gravity or vibration, the side wall of the temporary storage chamber is an inclined surface to form a flared inclined wall, and the bottom contour of the flared inclined wall close to the bottom of the temporary storage chamber is smaller than the outer opening of the flared inclined wall.

[0010] Furthermore, in order to further improve the self-cleaning effect of the tire of the vehicle equipped with the utility model, at least one set of vibrating wheels is provided on the sidewall, and the vibrating wheels and the sidewall are in rolling cooperation.

[0011] Furthermore, in order to enable the vibration wheel to have vibration capability, two groups of vibration wheels are provided, each group of vibration wheels is rotatably matched with a clamping plate of a plate-like structure, the two groups of clamping plates are vertically fixed on a motor fixing plate of a plate-like structure, a vibration motor is fixed on the motor fixing plate in the area between the two groups of clamping plates, a fixing bracket installed on the side of the vehicle body is connected to the motor fixing plate, and the fixing bracket is fixed on the vehicle body carrying the tire of the utility model.

[0012] Furthermore, in order to ensure that the vibration wheel can still maintain good rolling contact with the sidewall when the sidewall is compressed and deformed, the fixed bracket and the motor fixing plate are elastically connected through an inner cylinder, an outer cylinder, and a spring. The inner cylinder is vertically fixed to a side of the motor fixing plate close to the fixed bracket, and the outer cylinder is fixed to a side of the fixed bracket close to the motor fixing plate. The inner cylinder is slidably embedded in the outer cylinder, and a spring is connected between the end face of the outer cylinder and the motor fixing plate. The spring is concentrically embedded on the inner cylinder, and the spring has an elastic tendency to stretch.

[0013] Furthermore, in order to prevent the mud and dirt from accumulating on the vibration wheel, affecting the rotation of the vibration wheel and thus affecting the vehicle's driving force, a concentric disturbance impeller is fixed on the opposite surface of each set of vibration wheels, and the disturbance impeller is provided with a circumferential array of disturbance blades.

[0014] In summary, the utility model has the following beneficial effects:

[0015] By establishing the first oblique groove, the second oblique groove and the temporary storage cavity, when the first oblique groove and the second oblique groove with soil embedded therein are rotated to a vertical position, the soil in the temporary storage cavity is loosened first due to the effect of the flared oblique wall, and the soil in the first oblique groove and the second oblique groove is squeezed under the action of gravity. Under the vibration of the agricultural vehicle itself or the vibration of the auxiliary cleaner, the soil in the temporary storage cavity squeezes out the soil in the first oblique groove and the second oblique groove, or directly shakes off the soil in the first oblique groove and the second oblique groove, thereby completing simple self-cleaning of the tire and maintaining the anti-skid effect of the tire pattern.

[0027] The second oblique groove 4 and the first oblique groove 3 have the same structure except for the direction. The first oblique groove 3 has a notch on the shoulder 2 side to form a shoulder mud outlet 33 (the second oblique groove 4 has the same structure, so it is not repeated).

[0028] The groove depth of the first oblique groove 3 away from the mud discharge port 33 is greater than the groove depth of the first oblique groove 3 close to the mud discharge port 33; the upper and lower walls of the first oblique groove 3 are respectively an upper oblique wall 32 and a lower oblique wall 31; the lower oblique wall 31 and the upper oblique wall 32 are arranged parallel to each other.

[0029] The side wall of the temporary storage cavity 5 is an inclined surface, forming an expanded inclined wall 51 , and the bottom contour of the expanded inclined wall 51 close to the bottom of the temporary storage cavity 5 is smaller than the outer opening of the expanded inclined wall 51 .

[0030] At least one set of vibrating wheels 65 is provided at the sidewall 7 , and the vibrating wheels 65 and the sidewall 7 are in rolling cooperation.

[0031] The vibration wheels 65 are provided with two groups, each group of vibration wheels 65 is rotatably matched with a clamping plate 63 of a plate-like structure, the two groups of clamping plates 63 are vertically fixed on a motor fixing plate 62 of a plate-like structure, a vibration motor 64 is fixed on the motor fixing plate 62 in the area between the two groups of clamping plates 63, the motor fixing plate 62 is connected to a fixing bracket 61 installed on the side of the vehicle body, and the fixing bracket 61 is fixed on the vehicle body carrying the tire of the utility model.

[0033] A concentric disturbance impeller 66 is fixed on the opposite surface of each set of vibration wheels 65, and a circumferential array of disturbance blades is provided on the disturbance impeller 66.

[0034] First embodiment (the utility model does not install the auxiliary cleaner 6 and is suitable for agricultural machinery with a large vibration amplitude, such as tractors and grain harvesters):

[0035] The tire of the utility model is installed on the wheel hub of an agricultural vehicle. When the agricultural vehicle is working in a farmland, because the tread crown 1 is in contact with the soil in the farmland, the first oblique grooves 3 and the second oblique grooves 4 which play an anti-skid role will inevitably be embedded with mud. Under the dead weight of the vehicle body, a part of the mud entering the first oblique grooves 3 and the second oblique grooves 4 will be squeezed into the first oblique grooves 3 and the second oblique grooves 4 and discharged from the shoulder mud outlet 33 while a part of the mud will be squeezed into the temporary storage cavity 5. The wheel continues to rotate. When the first oblique grooves 3 and the second oblique grooves 4 with mud embedded in them rotate to Figure 1 When the tire is in position A, the soil in the temporary storage cavity 5 is loosened first due to the effect of the flared oblique wall 51, and the soil in the first oblique groove 3 and the second oblique groove 4 is squeezed out by gravity. Under the vibration of the agricultural vehicle, the soil in the temporary storage cavity 5 pushes out the soil in the first oblique groove 3 and the second oblique groove 4, or directly shakes off the soil in the first oblique groove 3 and the second oblique groove 4, thereby completing simple self-cleaning of the tire.

[0036] Second embodiment (the utility model is equipped with an auxiliary cleaner 6 and is suitable for agricultural machinery with a small vibration amplitude and a slow travel speed):

[0037] The tire of the utility model is mounted on the wheel hub of the agricultural vehicle, and the fixing bracket 61 on the auxiliary cleaner 6 is fixed on the shell or bracket of the agricultural vehicle, and the fixing setting is maintained, so that the vibration wheel 65 on the auxiliary cleaner 6 and the sidewall 7 are in rolling cooperation, the vibration motor 64 on the auxiliary cleaner 6 is powered, and the vibration motor 64 is started to work to generate vibration, and the vibration motor 64 transmits the vibration to the vibration wheel 65 through the clamping plate 63. Because the vibration wheel 65 and the sidewall 7 are in rolling cooperation, the vibration wheel 65 drives the entire wheel through the sidewall 7. Tire vibration (including crown 1, shoulder 2, sidewall 7); when agricultural vehicles are working in farmland, because crown 1 is in contact with soil in farmland, first oblique groove 3 and second oblique groove 4 which play anti-skid role will inevitably be embedded with soil. Under the deadweight of vehicle body, part of soil which enters first oblique groove 3 and second oblique groove 4 will be squeezed into first oblique groove 3 and second oblique groove 4 and discharged from shoulder mud outlet 33 at the same time, and the other part of soil will be squeezed into temporary storage cavity 5. When the wheel continues to rotate, when first oblique groove 3 and second oblique groove 4 with soil embedded in them rotate to Figure 1When the tire is in position A, the soil in the temporary storage chamber 5 is loosened first due to the effect of the flared oblique wall 51, and the soil in the first oblique groove 3 and the second oblique groove 4 is squeezed out by gravity. Under the vibration provided by the vibration wheel 65, the soil in the temporary storage chamber 5 squeezes out the soil in the first oblique groove 3 and the second oblique groove 4, or directly shakes off the soil in the first oblique groove 3 and the second oblique groove 4, thereby completing simple self-cleaning of the tire (due to the working needs of agricultural machinery, its driving speed is slow, so an auxiliary cleaner 6 is installed on the outside of the tire, and the rotation speed of the tire is slow, so the problem of damage to the auxiliary cleaner after the tire hits will not occur).
