Abstract

FIELD: machine building.

SUBSTANCE: proposed chassis comprises rims running in one direction and provided with outer gearing wheels, and tires-tracks. Inner line of rims is fitted on hollow shafts mounted on shaft aligned therewith to make mounts for outer line of rims. Inner line rims are connected in pairs with joining tire-track starting from the first rim is seen along chassis motion. Outer line pairwise connection of rims with joining tire-track is shifted relative to inner line connection of rims.

EFFECT: higher floatation.

Description

The invention relates to transport engineering, and in particular to wheeled-tracked vehicles, and can be used to increase cross-country ability on weakly bearing soils and to overcome obstacles such as public flight of stairs.

Known wheel-tracked chassis / cm. US Pat. No. 23228259 (class A61G 5/06) dated 04/02/2007 /, containing from each side of the vehicle a pair of rims driven in unidirectional rotation, with external gears and track tires, covering the rims and made in the form of a ring gear over internal generatrix.

With all the advantages of the known chassis, its patency is limited, especially on weakly bearing soils.

To eliminate the noted drawback in the wheel-caterpillar chassis, containing rims driven in unidirectional rotation, with external gears and tire tracks, covering the rims and made in the form of a ring gear along the entire inner generatrix; each side of the chassis has two rows of at least three rims in a row, the inner row of which is mounted on hollow shafts mounted on coaxial shafts that serve as seats for the outer row of rims, with the rims in the inner row starting from the first in the direction of travel the chassis is pairwise connected by a unifying tire-caterpillar, and the pairwise connection of rims by a unifying tire-caterpillar in the outer row is offset with respect to the connection of the rims in the inner row. The axis of rotation of the rims may be in a straight line.

-образной ломаной линии, где α не обязательно равно β≠0, если число ободов в каждом ряду нечетное количество, но не меньше 5. При этом оси вращения ободов могут находиться в вершинах равносторонних многоугольников, если число ободов в каждом ряду четное количество, но не меньше 6.In this case, the axis of rotation of the rims can be on

-shaped broken line, where α is not necessarily equal to β ≠ 0, if the number of rims in each row is an odd number, but not less than 5. Moreover, the axis of rotation of the rims can be at the vertices of equilateral polygons, if the number of rims in each row is an even number, but not less than 6.

In this case, the axis of rotation of the rims can be on a closed continuous chain of pivotally connected links-pairs of rims connected by combining tire tracks.

Moreover, the rotation of the rims in different rows can be multidirectional.

The invention is illustrated in FIGS. 1 and 2, where a wheel-tracked chassis of the starboard side of a vehicle with five and six rims in rows (I and II), respectively, is simplified. Figure 3 presents a variant of the wheel-caterpillar chassis with the axes of rotation of the rims on a closed continuous chain of articulated links-pairs of rims connected by connecting tire tracks.

The caterpillar-wheel chassis is a rim 1 driven in unidirectional rotation (drives not shown), with external gears and track tires 2, covering the rim 1 and made in the form of a ring gear over the entire inner generatrix. The inner row of rims (I) is mounted on hollow shafts 3 mounted on coaxial shafts 4 that serve as seats for the outer row of rims (II). The rims 1 in the inner row I, starting from the first in the direction of travel of the chassis, are pairwise connected by a connecting tire-track 2, and the pairwise connection of the rims 1 by a connecting tire-track 2 in the outer row II is made with an offset L with respect to the connection of the rims 1 in the inner row I. On rims 1 that do not have pairs in the corresponding row (lower rim 1 in row I and upper rim 1 in row II in figure 1), tire tracks 5 are mounted that are similar in design to tire tracks 2 and differ from the latter only long.

In different versions of the proposed wheel-caterpillar chassis, the axis of rotation of the rims 1 may be: a) in a straight line / skid (float) implementation option / (see figures 1 and 2);

-образной ломаной линии (см. фиг.3), где α не обязательно равно β≠0, если число ободов 1 в каждом ряду (I и II) нечетное количество, но не меньше 5 /лыжный вариант реализации/; в) в вершинах равносторонних многоугольников, если число ободов 1 в каждом ряду (I и II) четкое количество, но не меньше 6 /колесный вариант реализации/; г) на замкнутой сплошной цепи из шарнирно соединенных звеньев-пар ободов 1, соединенных объединяющими шинами-гусеницами 2 (см. фиг.3).b) on

-shaped broken line (see figure 3), where α is not necessarily equal to β ≠ 0, if the number of rims 1 in each row (I and II) is an odd number, but not less than 5 / ski version of the implementation /; c) at the vertices of equilateral polygons, if the number of rims 1 in each row (I and II) is a clear number, but not less than 6 / wheeled version of implementation /; d) on a closed continuous chain of articulated links-pairs of rims 1 connected by unifying tracks-tracks 2 (see figure 3).

In a ski embodiment of a wheeled-tracked chassis, the links carrying the extreme rims 1 at an angle α and β (see FIG. 3) may have a spring-loaded angular limiter (not shown).

In a single-breasted embodiment of the implementation of the wheel-caterpillar chassis, the rotation of the rims 1 in different rows (I and II) can be multidirectional, which extends the functionality of the proposed technical solution.

The wheel-caterpillar chassis of the proposed design works in the image and likeness of an analogue (prototype) / cm. US Pat. No. 23228259 (class A61G 5/06) dated 04/02/2007 /.

The proposed technical solution of the wheel-caterpillar chassis can be equipped with tires-tracks of the author's design / see, for example, US Pat. No. 2345904 (class B60B 19/00) dated 02/19/2007 and No. 2381944 (class B62D 55/253) dated December 17, 2008 /.

Thus, according to the applicant, the proposed wheeled tracked chassis is new, has an inventive step and is industrially applicable.
