Description

Technical Field

[0001] The invention relates to an anti-sinking and anti-skidding device for automobile tires, belonging to the technical field of automobile auxiliary walking devices. Background Art

[0002] With the continuous improvement of people's living standards in my country, cars have been widely used in people's daily lives, bringing great convenience to people's lives. The entry of cars into family life has also made people's lives more colorful. Self-driving tourism has become a common daily routine for ordinary people, but it has also brought driving troubles caused by poor road conditions. For example, on snowy, sandy and swampy muddy roads, vehicle tires are very likely to slip and sink, affecting the normal driving of the car and causing safety hazards.

[0003] At present, the devices on the market to solve the problem of anti-sinking and anti-skidding of automobile tires generally use methods such as tyring metal chains or plastic-coated steel wire ropes, plastic strips, etc. on the surface of the tire to increase the friction between the tire and the ground to achieve the purpose of anti-skidding and anti-sinking.

[0004] The Chinese invention patent with application number 2015109858671 and title: A vehicle tire anti-sinking device and the invention patent with application number 201420632425X and title: A vehicle tire anti-skid device, both have additional devices designed and installed on the tire surface to increase the friction between the tire and the ground, so as to achieve the purpose of anti-skidding and anti-sinking of the vehicle tire.

[0005] The characteristics of the above two patents are that the additional devices installed on the tire surface increase the embedding force and friction between the tire and the ground. Because the additional devices installed on the tires of the above two technologies are intermittent, the anti-skid and anti-sinking effects of the tires are also limited. The disadvantage is that the friction force area between the tire and the ground is not changed, the friction force increased by its anti-skid additional device is limited, and the force per unit area of ​​the tire is not changed. The effect of solving the anti-sinking problem of automobile tires is not obvious, and it can only play a certain anti-skid effect, so the anti-skid and anti-sinking effects of the tires are not good. Summary of the invention

[0006] The purpose of the present invention is to provide an automobile tire anti-sinking and anti-skidding device which is installed on the main driving wheel of an automobile and runs synchronously with the main driving wheel to increase the contact area between the main driving wheel and the ground; it assists the automobile to drive safely on snow, sand, swamps, and muddy roads and plays an anti-sinking and anti-skidding role.

[0007] The object of the present invention is achieved in the following ways:

[0008] The trolley assembly is a device for preventing automobile tires from sinking and skidding, and the trolley assembly is characterized in that the trolley assembly comprises a center positioning disk and automobile wheel spoke hooks and pressure blocks connected to the circumference of the center positioning disk and distributed at equal intervals; a positioning cone is provided at the center position of one side of the center positioning disk, and a main driving shaft is provided at the center position of the other side; the traveling mechanism comprises a main supporting plate connected to the main driving shaft through a bearing, a main pulley fixed to the main driving shaft at the outer end of the main supporting plate, a movable plate connected to the lower end of the main supporting plate, a traveling wheel shaft arranged at the same height under the movable plate, a secondary pulley and a traveling wheel are fixed on the traveling wheel shaft, the other end of the traveling wheel shaft is rotatably connected to a secondary supporting plate through a bearing, symmetrically distributed shock absorbers are provided between the main supporting plate and the secondary supporting plate, a pressure plate for limiting the shock absorber is fixed on the top of the main supporting plate, the secondary pulley on the traveling wheel shaft is connected to the main pulley through a belt, a tensioning wheel is provided on the belt, and the tensioning wheel is mounted on the main supporting plate.

[0009] The pressure block and the spoke hook are connected by a compression bolt.

[0010] A rubber track is arranged between the traveling wheels.

[0011] The pressing plate is L-shaped.

[0012] The advantages of the present invention are: first, the present invention is installed on the outside of the vehicle's power drive wheel, which is easy to install and firmly combined with the power drive wheel. Because two running wheels are added, the contact area between the vehicle tire and the ground is objectively increased, and the running wheels and the power drive tires run synchronously, similar to the effect of tractor tracks, so they can play a good role in anti-skid and anti-sinking; second, because the present invention is designed with structures such as belt transmission, movable plates and shock absorbers, the running wheels can avoid rigid collisions during the driving process even if there are protruding hard objects on the ground; third, the linear speed of the running wheels of the present invention in contact with the ground is the same as the linear speed of the main drive tires, and both are power wheels, which objectively increases the number of driving wheels of the vehicle, so they can play a better role in anti-skid and anti-sinking.

DETAILED DESCRIPTION

[0019] Referring to the accompanying drawings, the present invention is composed of a fixed plate fixture and a traveling mechanism, wherein the fixed plate fixture includes a center positioning plate 2 and connected to the center positioning plate 2 at equal intervals on the circumference thereof, and is composed of automobile spoke hooks 21 and pressure blocks 20, wherein the number of spoke hooks 21 matches the number of main driving wheel spokes 22 of the vehicle, and is generally 5 to 9; a positioning cone 4 is provided at the center position of one side of the center positioning plate 2, and a main driving shaft 3 is provided at the center position of the other side; the traveling mechanism includes a main supporting plate 1 connected to the main driving shaft 3 through a bearing 5, a main pulley 6 fixed to the main driving shaft 3 at the outer end of the main supporting plate 1, and a movable plate 8 connected to the lower end of the main supporting plate 1 , a group of walking wheel shafts 11 are arranged at the same height below the movable plate 8; a secondary pulley 9 and a walking wheel 10 are fixed on the walking wheel shaft 11, and a rubber track 17 is arranged between the walking wheels 10 on the walking wheel shaft 11, and the other end of the walking wheel shaft 11 is connected to a secondary supporting plate 12 through a bearing, and symmetrically distributed shock absorbers 13 are arranged between the main supporting plate 1 and the secondary supporting plate 12, and a pressure plate 14 for limiting the shock absorber 13 is fixed on the top of the main supporting plate 1, and the pressure plate 14 is L-shaped, and the secondary pulley 9 on the walking wheel shaft 11 is connected to the main pulley 6 through a belt, and a tensioner 16 is arranged on the belt, and the tensioner 16 is installed on the main supporting plate 1.

[0020] The main supporting plate 1 is a rectangular plate, and a shock absorber connecting ear 15 is symmetrically provided on the top of the main supporting plate 1. The upper end of the shock absorber 13 is connected to the shock absorber connecting ear 15 through a second connecting pin, and the lower end of the shock absorber 13 is connected to the auxiliary supporting plate 12; a movable plate connecting groove 19 is symmetrically opened on the bottom edge of the main supporting plate 1; the movable plate 8 is a rectangular plate, and a connecting ear 18 matching the movable plate connecting groove 19 on the main supporting plate 1 is provided on the top of the movable plate 8. The connection method of the movable plate 8 and the main supporting plate 1 is to insert the connecting ear 18 of the movable plate 8 into the movable plate connecting groove 19 on the main supporting plate and fix it with a pin bolt 7; the auxiliary supporting plate 12 is a rectangular plate; the set of walking wheel shafts 11 is two, which are respectively arranged on both sides of the same side of the movable plate 8 and are symmetrically distributed on the left and right.

[0021] The shock absorber 13 is one of a spring shock absorber, a hydraulic shock absorber, an air shock absorber or a magnetic shock absorber.

[0022] The main pulley 6 and the main drive shaft 3 are connected in a key connection. There are two belt grooves on the main pulley 6. The two belts in the belt grooves respectively drive the auxiliary pulley 9 on the walking wheel shaft 11 to move. The walking wheel shaft 11 is key-connected with the auxiliary pulley 9 and the walking wheel 10, so the walking wheel 10 moves at the same speed as the auxiliary pulley 9 and the walking wheel shaft 11, driving the rubber track 17 on the walking wheel 10 to move; the outer surface of the walking wheel 10 has grooves, the outer surface area of ​​the rubber track 17 has an uneven pattern, and the inner surface has grooves, which are engaged with the grooves on the outer surface of the walking wheel 10, which not only increases the force area of ​​the tire when the vehicle is walking, but also increases the friction.

[0023] The contact portion between the L-shaped pressure plate 14 and the shock absorber 13 is a V-shaped structure with an opening downward, which is buckled on the shock absorber 13 and can effectively limit the shock absorber 13 from rotating around the second connecting pin 23 .

[0024] The clamping block 20 and the spoke hook 21 are connected by a clamping bolt and fixed on the main driving wheel spoke of the vehicle. The hook opening direction of the spoke hook 21 is opposite to the moving direction of the vehicle. Figure 4 The direction of the arrow V in the middle indicates the direction of movement of the wheel.

[0025] When the car encounters snow, sand, swamp, mud and other road conditions, and the present invention needs to be used, the installation method is as follows: put the positioning cone 4 of the center positioning plate 2 into the center hole of the main driving wheel hub of the car, the spoke hook 21 clamps the main driving wheel spoke 22, and the fixing plate clamp is firmly fixed on the main driving wheel spoke 22 through the pressing block 20 and the bolts thereon, and the installation of the present invention is completed.

[0026] When the vehicle is moving, the main driving wheel of the vehicle rotates, and the center positioning plate of the present invention rotates synchronously with the main driving wheel of the vehicle. The main driving shaft on the center positioning plate also rotates synchronously, and the main driving shaft drives the main pulley and then drives the secondary pulley to move, thereby driving the running wheel to rotate, so that the rubber track moves synchronously with the main driving wheel of the vehicle. This not only increases the power wheels of the vehicle, but also increases the force-bearing area of ​​the tires when the vehicle is moving, and also increases the friction force, which is similar to the function of tractor tracks, so it can better play an anti-skid and anti-sinking role.
