Abstract
The utility model relates to a wheel without an inner tube used for engineering vehicles. A spoke is welded on a wheel rim. The spoke is a structure without a vent; and the wheel rim is an integrative structure. A valve cover is welded at a round valve in the wheel rim. The wheel structure is simple with material saving and easy to process for more process accuracy, and air sealing, long period of usage. The valve is not easy to be destroyed during operation for more safety.
Description
Technical field:
The utility model relates to a kind of inner tube-free wheel that construction machinery and equipment uses that is used for.
Background technology:
The employed wheel of former construction machinery and equipment generally is formed by connecting by wheel rim, back-up ring, three of spokes, for inner tube of a tyre multi-piece type shaped steel wheel is arranged, though easy disassembling, but the consumption material is many, and under bad working environment, since the friction of tire Tire ﹠ Tube, the tire temperature rise, cause shorten greatly the service life of tire, also need too much elastomeric material such as the inner tube of a tyre, pad tire.
Summary of the invention:
The purpose of this utility model provides a kind of construction machinery and equipment inner tube-free wheel, and is simple in structure, saves material, and processing can improve working accuracy, air-tightness easily, increase the service life, and tire tube valve is not easy to destroy in work progress, has improved safety.
The purpose of this utility model realizes as follows: this wheel relates to the wheel rim and the spoke of weld together, and wheel rim is an one-piece construction, has saved back-up ring, can be equipped with tubeless tires.
There is a protective cover at wheel rim valve port place, avoids construction machinery and equipment to destroy tire tube valve in work progress, has improved the safety of wheel.
Spoke can adopt cold isostatic compaction for saving the breather port structure, and moulding is easy, and manufacturing cost is lower, and production efficiency is higher, saves spoke again towards the breather port operation simultaneously.
This project machinery inner tube-free wheel wheel rim is an one-piece construction, after the inflation of assembling tubeless tires, makes it reach good mated condition, produces sealing effectiveness.It substitutes multi-piece type construction machinery and equipment shaped steel wheel, and is simple in structure, drops into not quite, has fundamentally stopped the problem that former construction machinery and equipment shaped steel wheel occurs easily, and the advantage of having given prominence to this inner tube-free wheel; The place is welded with a protective cover at the wheel rim valve port, has improved the safety of wheel; Spoke is improved design, save the spoke breather port, cold isostatic compaction is adopted in moulding, and moulding is easy, and manufacturing cost is lower, and production efficiency is higher, saves spoke again towards the breather port operation simultaneously; Single type inner tube free one-piece construction wheel rim makes engineering machinery vehicle cancel the inner tube of a tyre and pad tire, has simplified tire production and dress tire technology, has saved raw MAT'L; The inner tube free structure of this product has avoided the inner tube of a tyre, cover tire, pad tire and wheel rim to rub and the phenomenon of generation heat mutually in the vehicle ' process; The performance of ventilation and heat dispersion of inner tube free structure is good simultaneously, the life-span of having improved tire; Through improvement the design-calculated product have littler radially, the face runout amount, kinetic balance is effective, has improved the stationarity of car load, it is more comfortable to drive a vehicle; More can or not puncture and blow out because of heating, improved travel safety, can satisfy the requirement of engineering machinery vehicle, the wheel Combination property improves greatly, have traditional construction machinery and equipment shaped steel wheel incomparable advantage, satisfied of the requirement of present construction machinery and equipment to inner tube-free wheel.
Description of drawings:
Accompanying drawing is the structural representation of the utility model construction machinery and equipment inner tube-free wheel.
The specific embodiment:
With reference to accompanying drawing, spoke 3 is welded on the wheel rim 1, and spoke 3 is for saving the breather port structure, and wheel rim 1 is an one-piece construction, and circle valve port place is welded with a valve protective cover 2 in the wheel rim 1.
