Description
Affiliated technical field
The present invention relates to the tire device that a kind of engineering truck uses.
Background technology
At present, the tire that known engineering truck uses all is air tyrees, owing on the building site iron nail, sharp shaped material are arranged, therefore, tire is punctured and leaks gas, and causes vehicle to have to quit work and removes tire patching, reduce the work efficiency of vehicle, shorten the service life of tire, increase the use cost of tire.
Summary of the invention
The deficiency of leaking gas for the tire that overcomes existing engineering truck use is often punctured by the iron nail on the building site, sharp shaped material, the invention provides the tire device that a kind of engineering truck uses, this device does not need to use inflatable inner tube, has improved the service life of tire, has reduced the use cost of tire.
In order to achieve the above object, the technical solution adopted for the present invention to solve the technical problems is following design-calculated:
Steel ring large circle and steel ring small circle ring are arranged on the steel ring, central authorities are circular holes, the well-distributed mounting hole is arranged around the circular hole, cylinder body, hold that cylinder connects piece by a cylinder body respectively and the steel ring small circle ring is connected as a single entity, the left end that holds cylinder has valve nozzle, its right-hand member is communicated with an end of gas connecting leg, and the other end of gas connecting leg is communicated with the cylinder body lid.Paired and well-distributed Luo bar cover are arranged on the steel ring small circle ring, every pair of Luo bar cover connects the lower end of a fore-set cylinder body by a Luo bar, a Luo cap, the bottom of each fore-set cylinder body has a fore-set cylinder body oil pipe to be communicated with circular oil pipe, and the upper end of each fore-set cylinder body is stretched on the steel ring large circle and fixed; The lower end of each fore-set is inserted respectively in the fore-set cylinder body, and its upper end is supported a jacking block respectively, all jacking block together support tire; The bottom of each jacking block has many to steel rope sleeve, and steel cable passes the steel rope sleeve on the jacking block respectively and strains jacking block.One end of oil pipe is communicated with circular oil pipe, and the other end is communicated with the left end of cylinder body, and air extractor vent is arranged on the cylinder body.
During use, the right-hand member of oil from cylinder body injected in circular oil pipe, each fore-set cylinder body, then piston is put into cylinder body, again cylinder body is built cylinder body and fastening with screw, subsequently, with the circle hole sleeve of steel ring central authorities on the axle drive shaft of self-propelled vehicle, and fix by mounting hole, then, by valve nozzle to holding the sufficient high pressure gas of cylinder and cylinder body right part, at this moment, the pressure of the gas on the pressure of the oil on the piston left side and piston the right reaches a kind of balance.In the vehicle driving process, when tire is under pressure increase, tire promotes the center direction motion of fore-set to steel ring, the pressure of oil is increased, thereby promoting other fore-set moves right and pressure gas to the center position that leaves steel ring, piston, the pressure of gas is increased gradually, reach new balance to the pressure of the pressure of gas and oil.Otherwise when the pressure that is subjected to when tire reduced, gas promoted piston to left movement, promote fore-set to the center position motion of leaving steel ring through oil, make the tire expansion through jacking block, along with piston moves to left, gaseous tension reduces, and reaches new balance to the pressure of the pressure of gas and oil.Simultaneously, jacking block is subjected to the tractions of many group steel cables, restriction fore-set expansionary force and make tire keep positive toroidal, and air extractor vent is not subjected to atmospheric influence when guaranteeing pistons work.
The invention has the beneficial effects as follows: do not need to use inflatable inner tube, improved the service life of tire, reduced the use cost of tire, simple in structure, easy to use.

The specific embodiment
In Fig. 1, Fig. 2, embodiment shown in Figure 3, steel ring large circle 6, steel ring small circle ring 8 are arranged on the steel ring 5, central authorities are circular holes 22, on the disk 5 around the circular hole 22 well-distributed mounting hole 1 is arranged, cylinder body 2, hold that cylinder 19 connects piece 3,17 by cylinder body respectively and steel ring small circle ring 8 is connected as a single entity, the left end that holds cylinder 19 has valve nozzle 18, and its right-hand member is communicated with an end of gas connecting leg 24, and the other end of gas connecting leg 24 is communicated with cylinder body lid 27.Have paired on the steel ring small circle ring 8 and well-distributed Luo bar cover 9, every pair of Luo bar cover 9 connects the lower end of a fore-set cylinder body 15 by a Luo bar 7, a Luo cap 23, the bottom of each fore-set cylinder body 15 has a fore-set cylinder body oil pipe 29 to be communicated with circular oil pipe 16, and the upper end of each fore-set cylinder body 15 is stretched on the steel ring large circle 6 and fixed; The lower end of each fore-set 14 is inserted respectively in the fore-set cylinder body 15, and its upper end is supported a jacking block 20 respectively, all jacking block 20 together support tires 13; The bottom of each jacking block 20 has many to steel rope sleeve 10, and steel cable 11 passes the steel rope sleeve 10 on each jacking block 20 respectively and strains jacking block 20.One end of oil pipe 4 is communicated with circular oil pipe 16, and the other end is communicated with the left end of cylinder body 2, and air extractor vent 28 is arranged on the cylinder body 2.
During use, oil 21 right-hand members from cylinder body 2 are injected in circular oil pipe 16, each fore-set cylinder body 19, then piston 26 is put into cylinder body 2, again cylinder body lid 27 is built cylinder body 2 and fastening with screw 30, subsequently, the circular hole 22 of steel ring 5 central authorities is enclosed within on the axle drive shaft of self-propelled vehicle, and it is fixing by mounting hole 1, then, by valve nozzle 18 to holding the sufficient high pressure gas 25 of cylinder 19 and cylinder body 2 right parts, at this moment, the pressure of the gas 25 on the pressure of the oil 21 on piston 26 left sides and piston 26 the right reaches a kind of balance.In the vehicle driving process, when tire 13 is under pressure increase, tire 13 promotes the center direction motion of fore-set 14 to steel ring 5, the pressure of oil 26 is increased, thereby promoting other fore-set 14 moves right and pressure gas 25 to the center position that leaves steel ring 5, piston 26, the pressure of gas 25 is increased gradually, reach new balance to the pressure of the pressure of gas 25 and oil 21.Otherwise, when the pressure that is subjected to when tire 13 reduces, gas 25 promotes piston 26 to left movement, promote fore-set 14 to the center position motion of leaving steel ring 5 through oil 21, make tire 13 expansions through jacking block 20, along with piston 26 moves to left, gas 25 pressure reduce, and reach new balance to the pressure of the pressure of gas 25 and oil 21.Simultaneously, jacking block 20 is subjected to the traction of two steel cables 11, restriction fore-set 14 expansionary forces and make tire 13 keep positive toroidal, and air extractor vent 28 is not subjected to atmospheric influence when guaranteeing pistons 26 work.
