The invention relates to the combined wheels vehicles.

Known combined wheel /see PM No. 105858 (CL VV 15/26) dated 08.11.2010/, consisting of two rows of identical small wheels attached in a checkerboard pattern on the rim with a brake band by means of the brackets with hinges. To provide adhesion of small wheels with a brake band in the bottoms of the joints are cut.

The lack of a combined wheel-prototype is unnecessarily complicated technology, installation and operation of a combined wheel.

To correct the noted deficiency in the combined wheel, consisting of two rows of small wheels, arranged in a checkerboard pattern on the rim, small wheels are hollow elastic reinforced synthetic and/or metal cord, alternating in a series of wheels in the form of a barrel with a wheel in the shape of a hyperboloid with the same form in the form of an arc of a circle, and a common shaft adjacent in axial relation to the hollow wheel of the joint closed with bands or chains. At the periphery of the rim can be two profiled grooves are two rows of small barrel-shaped wheels.

The drawing shows a fragment of the small wheels of the proposed construction of a combined wheel.

Combined wheel consists of two rows (I and II) small wheels 1 and 2, located in W is Haltom order on the rim (not shown). Small wheels 1 and 2 are hollow elastic reinforced synthetic and/or metal cord, alternating in a series of wheels in the form of a barrel (1 in the drawing) with the wheel in the form of a hyperboloid (see item 2 in the drawing) with the same form in the form of an arc of a circle, and a common shaft (3 or 4 in the drawing) adjacent in axial relation to the hollow wheels (1 and 2 in the drawing) of the United closed belts or chains (not shown). At the periphery of the rim can be two profiled grooves under two rows (I and II) small barrel wheel 1.

The proposed construction of a combined wheel technologically simpler prototype in the manufacture, installation and operation as the clutch small wheels with rim is not the couple ' brake band - hinge cutouts, and a combination of gaps between adjacent hollow elastic wheels in the form of alternating barrels and hyperboloid. When the appropriate pressure in each of the hollow wheels you can get quasiplane the tire on the rim offer a combined wheel with the best possible coupling performance on the road. Moreover, if the periphery of the rim has two profiled grooves are two rows of small barrel-shaped wheels.

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

1. Combined wheel, consisting of two rows of small wheels, arranged in a checkerboard pattern on the rim, characterized in that the small wheels are hollow elastic reinforced synthetic and/or metal cord, alternating in a series of wheels in the form of a barrel with a wheel in the shape of a hyperboloid with the same form in the form of an arc of a circle, and a common shaft adjacent in axial relation to the hollow wheel of the joint closed with bands or chains.

2. Combined wheel according to claim 1, characterized in that the periphery of the rim can be two profiled grooves are two rows of small barrel-shaped wheels.
