Description

Technical Field

[0001] The invention relates to a vehicle running device, belonging to the field of transportation vehicles. Background Art

[0002] The existing vehicles, whether they are two-wheeled, three-wheeled, four-wheeled or covered vehicles, all use several large wheels or covers to contact the ground and drive the vehicle to move. However, there are eight major problems with the existing technology. First, the rolling resistance of the vehicle's running device is large. Second, the wind resistance of the running device is large. Third, the space occupied by the wheels or covers is large, which consumes a lot of energy and reduces the effective space of the vehicle. Fourth, the cover device itself is very heavy and has a large contact area with the ground, which wastes energy and makes it difficult to turn. Fifth, the cover is easily damaged by the front and rear tensile forces, the friction with the ground, the puncture of sharp objects on the ground, etc. Sixth, the cover is easy to fall off. Seventh, the covered vehicle cannot travel and turn at high speed. Eighth, the tire burst of the vehicle at high speed will cause serious safety problems.

[0003] The purpose of the present invention is to invent a vehicle running device to replace the prior art, so that the vehicle can overcome at least the above-mentioned eight problems. Summary of the invention

[0004] In order to achieve the purpose of the present invention, the technical solution of the present invention is: a vehicle travel device, its technical characteristics are: the vehicle travel device is composed of two groups of devices arranged on the left and right sides of the vehicle, each group of devices has a number of road wheels connected to the vehicle body and in contact with the ground by elastic components, each road wheel is connected to a sprocket or pulley or gear or other similar components, there is a driving gear or a driven gear, the driving gear is directly or indirectly connected to the power end output by the vehicle engine or motor, the above-mentioned driving gear or driven gear is connected to a sprocket or pulley or belt pulley or similar component, one or more chains or belts or toothed belts or other similar components are connected to the sprocket or pulley or gear or other similar components on the road wheel and the sprocket or pulley or gear or other similar components on the front and rear driving gears or driven gears, and there are two upper and lower groups of limiting wheels connected to the vehicle body by elastic components, so that the chain or belt or toothed belt or other similar components and the above-mentioned load-bearing gear are connected. The sprocket, pulley, gear or other similar components on the wheel and the driving gear or the driven gear are in close contact without slipping. Preferably, a protective baffle is connected below the wheel axle of the above-mentioned road wheel to prevent stones or other objects on the ground from damaging the sprocket, pulley or gear or other components on the road wheel. The above-mentioned driving gear or driven gear is connected to a transition wheel off the ground or a belt pulley or sprocket or other similar components on the road wheels at both ends of the vehicle by a belt or other component. The belt or other similar components here are used to cross obstacles on the ground or climb steps. The power output by the engine or electric motor of the above-mentioned vehicle drives the driving gear to rotate, and the driving gear or driven gear drives the chain, belt, toothed belt or similar component to transmit, and the chain, belt, toothed belt or other similar component drives the road wheel to rotate. At the same time, the rotation of the driving gear or driven gear also drives the belt or other similar components to move, so as to make the vehicle move forward or backward and cross obstacles and steps.

[0005] In the above-mentioned vehicle travel device, the active gear or the passive gear is preferably connected to the transition wheel off the ground by a belt or similar component, so that the rolling resistance is less. The connection method can be that the gear is directly connected to the belt or the belt wheel connecting the gear is connected to the belt.

[0006] The elastic component connected to the road wheel and the vehicle body can be a mechanical spring, an air spring or other elastic component. The purpose is to reduce the impact and vibration of the vehicle caused by uneven ground. The elastic component has a telescopic range of preferably 1 to 10 cm, which makes it easier to cross obstacles on the ground and climb stairs.

[0007] The telescopic range of the elastic component connected to the limiting wheel is preferably 1 to 10 cm.

[0008] The above-mentioned road wheels can be pneumatic wheels or non-pneumatic wheels, preferably non-pneumatic rubber wheels, which are safer and simpler. The buffering can be borne by the elastic components connected to the road wheels.

[0009] The steering, braking and reversing of the above-mentioned vehicle running device can imitate the methods of tanks or other covered vehicles.

[0010] The above-mentioned chain or belt or toothed belt or similar component is preferably located above the sprocket or pulley or gear or other similar component of the load-bearing wheel.

[0011] The above-mentioned driving gear and passive gear may also use only the driving gear without the passive gear, but in this case the chain or belt or toothed belt or similar components will be located below the sprocket or pulley or gear of the road wheel, so the chain or belt or toothed belt is not easily protected and is easily damaged by ground objects. Therefore, it is preferred to use a combination of driving gear and passive gear components at the same time.

[0012] The above-mentioned design of the present invention can achieve the following beneficial effects:

[0013] 1. The weight of the vehicle is distributed to multiple road wheels. The load on each wheel is light. Each road wheel only needs a small contact area with the ground to achieve sufficient contact area with the ground as a whole, so that the wheels and the ground can generate enough static friction to drive the vehicle forward. At the same time, since each road wheel has a smaller contact area with the ground, the deformation of each wheel is less, so the rolling resistance is less. The rolling resistance is proportional to the deformation of the wheel. If there are enough road wheels, the rolling resistance will become very small.

[0014] 2. The vehicle's running device occupies less space, so the vehicle's effective space becomes larger accordingly.

[0015] 3. Since the running device takes up less space, wind resistance is reduced.

[0016] 4. The traveling device becomes light, thus weighing less, and the contact area with the ground is similar to that of existing wheeled vehicles, making it easy to turn.

[0017] 5. The traveling device is not easily damaged.

[0018] 6. There is no problem of the cover tape falling off easily.

[0019] 7. It can travel and turn at high speed.

[0020] 8. Better safety. First, there will be no tire blowout. Second, the center of gravity of the vehicle is lower.

[0021] 9. The vehicle is fully weight-driven at the front and rear ends, similar to the four-wheel drive of wheeled vehicles, with good power.

[0022] 10. The drive is simple and reliable, eliminating the complex mechanism of the four-wheel drive in the prior art.

[0023] 11. The braking is simple and convenient, and only the chain or belt needs to be braked, which is simpler and more reliable than the four-wheel brake in the prior art.

[0024] 12. Better overall rigidity.

[0025] 13. It can reduce the vacuum area at the rear of the vehicle, thereby reducing the wind resistance at the rear.

[0026] The purpose of the present invention can be achieved through the above-mentioned technical solution of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, similar to Embodiment 2, the section of the power transmission chain or belt or similar component 6 that drives the road wheel 1 is placed below the sprocket or pulley or similar component 8 on the road wheel 1.
