Description

Novel energy-saving air spring wheel

Technical Field

The invention belongs to the technical field of energy-saving wheels, and particularly relates to a wheel which utilizes gravitational potential energy of a wheeled vehicle to convert the gravitational potential energy into kinetic energy of the wheel in the forward driving process so as to achieve the purpose of energy conservation.

Background

Wheeled vehicles must use a large amount of kinetic energy to overcome their own weight and resistance to forward motion to achieve a certain speed of travel. The greater the vehicle weight and road resistance, the more energy is consumed to move the vehicle. However, this energy requires a large amount of fuel and electricity to provide. People develop various utilization researches for fully utilizing the gravity of the vehicle to save energy consumption.

Chinese patent 200510022653.0 relates to a wheel capable of generating regenerative power during rotation by using the gravity of a vehicle, and is characterized in that a rim is composed of a peripheral annular plunger cylinder, a central rotating shaft sleeve, and a closed annular liquid medium tank therebetween; the central shaft of the rotating shaft sleeve is used as a wheel shaft, the outer rotating sleeve is used as a central shaft sleeve of the wheel rim, and a liquid flow circulating channel which is in rotating communication is arranged between the rotating shaft sleeve and the outer rotating sleeve; a hydraulic motor is connected in series between the central shaft circulating liquid channels; liquid outlets of the plunger hydraulic cylinders on the periphery of the rim are connected with liquid inlets of the outer rotating sleeves, and liquid outlets of the outer rotating sleeves and liquid inlets of the plunger hydraulic cylinders are connected with the annular liquid medium box.

Although the above patent can achieve the energy-saving effect, the hydraulic system is complex in connecting pipeline, more in accessories and poor in wheel practicability, and is difficult to be practically applied.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a wheel which has simple structure and easy manufacture, can fully utilize the gravitational potential energy of a wheeled vehicle and achieves the purpose of energy conservation in the forward driving process.

The implementation method of the invention comprises the following steps: eccentric plungers are uniformly arranged on the outer circumference of a gas spring cylinder body connected with a hub, and the eccentric plungers push a plunger cap to be tightly pressed on a tire under the action of high-pressure gas, so that when the wheel rotates, the eccentric plungers of the portion, contacting with the ground, of the tire are compressed by the vehicle and store energy, when the wheel continues to rotate, the plungers extend out one by one, and because the axial line of the plungers has an eccentric distance with the axial line of the wheel, the plungers release energy and act on the wheel to generate forward torque, and the forward torque and an engine drive the wheel to rotate. Because the wheel rotates at a high speed continuously, the compressed plunger continuously applies work to the wheel, thereby saving a large amount of energy.

Specifically speaking, the novel energy-saving gas spring wheel comprises a wheel hub, a gas spring cylinder body, an eccentric plunger, a tire, a plunger cap, a cylinder sleeve and the like. The gas spring cylinder is characterized in that eccentric holes which are communicated with each other are uniformly distributed on the outer surface of the gas spring cylinder body; the axis of the eccentric hole does not intersect with the axis of the wheel, but forms a straight line with the axis of the wheel, and the distance between the straight line and the axis of the wheel is the eccentricity; the eccentric hole is used for installing an eccentric plunger and a cylinder sleeve, and a plunger cap is installed on the eccentric plunger; the inner parts of the eccentric holes are communicated with each other and filled with high-pressure gas, the eccentric plungers extend out, and the plunger caps support the tires tightly.

The eccentric distance exists between the axial lead of the eccentric plunger in the gas spring cylinder body and the axial lead of the wheel.

The eccentric plunger piston is matched with the cylinder sleeve and is arranged on the air spring cylinder body through threads on the cylinder sleeve.

The top end of each eccentric plunger is connected with a plunger cap, and the eccentric plungers extend out of the gas spring cylinder sleeve after being inflated to support and tension the tire.

The hub and the gas spring cylinder body are made of light materials such as magnesium alloy, nylon, POM, PEER and the like, and are easy to process.

The tire adopts polyurethane, and the process flow of tire manufacturing is greatly shortened.

The hub and the gas spring cylinder body can be made into a whole body or can be made into a split body.

The invention has the beneficial effects that: through carrying out eccentric arrangement to the air spring, can make full use of vehicle gravitational potential energy produce forward torque, drive the wheel rotation with the engine together, the wheel rotational speed is faster, and energy-conserving effect is more obvious. Compared with the prior art, the structure is simple, the manufacture is easy, and the green manufacture can be realized.

The present invention will be further described with reference to the following examples, which should not be construed as limiting the scope of the present invention.

Description of reference numerals:

the pneumatic tire comprises a hub 1, a gas spring cylinder body 2, a tire 3, an eccentric plunger 4, a plunger cap 5, a guide sleeve 6, a sealing ring 7, an air chamber 8 and an air valve 9.

Detailed Description

A novel energy-saving gas spring wheel comprises a wheel hub, a gas spring cylinder body, an eccentric plunger, a tire, a plunger cap, a cylinder sleeve and the like.

The hub 1 and the gas spring cylinder body 2 are manufactured into a whole, 18 rows of holes are uniformly distributed on the circumferential surface of the gas spring cylinder body 2, the inner parts of the cylinder bodies are communicated with each other, the eccentric plunger 4 is installed in the air chamber 8 through the guide sleeve 6, and the sealing ring 7 plays a role in sealing the eccentric plunger 4.

The plunger cap 5 is pressed against the inner surface of the tire 3 by the eccentric plunger.

After the air spring cylinder body is inflated through the inflating valve 9, the eccentric plunger extends out, and the tire 3 is tensioned.

The wheel rotates at speed n in the direction of the arrow, the eccentric plunger at point a in fig. 1 comes into contact with the ground and is gradually compressed by the vehicle weight to store energy, giving the wheel a reaction force which reaches a maximum value f at point B. Due to the existence of the eccentricity e, the maximum torque obtained by the wheel at the point B is e multiplied by f, the faster the wheel rotates, the more eccentric plungers are involved in doing work, and the more obvious the energy-saving effect is.

The hub and the gas spring cylinder body are made of light materials such as magnesium alloy, nylon, POM, PEER and the like, and the wheel is light in weight and easy to process.

In this embodiment, the number of the eccentric plungers 4 can be adjusted according to the load and the use requirement.

The invention has simple structure and easy manufacture, and fully utilizes the gravitational potential energy of the vehicle to achieve the energy-saving effect.
