Chassis wheel

FIELD: transport.

SUBSTANCE: chassis wheel comprises rim on shaft and multiple grousers on rim periphery. Wheel rim part is not integral with the hub and is asymmetric therewith but runs in step therewith. Air tube of atmospheric pressure is fitted on said rim. The latter is shaped to cylindrical drum with flanges provided with through holes made in generatrix for grousers. Besides, said holes are formed in tire drum rim. Wheel rim part drive is composed of three spinning rollers, top one being intended for inner engagement with said flange and two bottom rollers arranged in symmetry with top one are intended for external engagement.

EFFECT: improved cross-country capacity.

The invention relates to the field of transport engineering, in particular to a wheeled chassis for wheelchairs.

Known wheel chassis /see. SVID. No. 1750682 (CL A61G 5/04) from 29.11.1988/ containing the disc-rim of the shaft and the set of lugs on the periphery of the rim.

The disadvantage of the wheels of the prototype is the low operational characteristics when driving on a loose surface (sand, peat, snow, etc.).

To address these shortcomings in the wheel chassis that contains the rim on the shaft and a set of lugs on the periphery of the rim, the rim portion of the wheel not being in one piece with the hub the hub and asymmetric, but rotated synchronously with the hub on which is mounted a pneumatic chamber atmospheric pressure, in the shape of a cylindrical drum having a flange with through-holes for forming the elastic lugs formed in the holes of the drum from pnevmostartery atmospheric pressure, the actuator rim part of the wheel is accomplished by means of three rotating rollers - upper for internal engagement with the flange and the bottom two symmetrical upper, for external engagement with the flange.

The drawing shows a wheel chassis, a side elevational view.

The proposed technical solution the wheel chassis contains a rim portion 1 in the form of a cylindrical drum having ribordy, with through holes (not shown) along generatrix of the drum under the elastic lugs (not shown) formed in the holes of the drum from pnevmostartery 3 atmospheric pressure, mounted inside diameter on the hub 4.

Rim portion 1 of the wheel is in one piece with the hub 4 and the asymmetrical hub 4, but rotated synchronously with the hub 4. The drive rim 1 of the wheel is accomplished by means of three rotating rollers - top 5 for internal engagement with the flange 2, and two (6 and 7) lower, symmetrical relative to the top 5, for external engagement with the flange 2.

The magnitude of the elastic lugs in the wheel chassis of the proposed design with the coaxial arrangement of cylindrical rim portion 1 relative to the hub 4 ceteris paribus, the higher the excess pressure of gas or air in the pneumatic chamber 3. The radial size of the elastic lugs in the wheel chassis of the proposed design is further increased near the contact patch of the wheel with the road in the right direction due to the radial movement through three (5, 6, 7) of the rotating rollers of the cylindrical rim portion 1 relative to the hub 4, improving the patency of the vehicle for loose material (sand, peat, snow, etc.), making comfortable navigating the road with a firm covering, and also at the entrance of´┐Że and descending the flight of stairs for General use.

Thus, the proposed technical solution, according to the applicant, is new, involves an inventive step and is industrially applicable.
