SU1660997A1 - Walking wheel of transport vehicle - Google Patents

Abstract

This invention relates to high-traffic engines. The purpose of the invention is to eliminate the resonant vibrations of the body. The walking wheel includes a housing 1, on the axis 2 of which the interconnected cranks 3 are mounted, driven by a gear wheel 4. The cranks 3 have an unequal angular location and unequal length. Rods 5 are hinged to their ends with supporting shoes 8 at the ends and rocking 9 that are hinged to a fixed axis 12 placed inside the circles of rotation of the hinges 6 of the cranks 3. The dimensions of all the same parts of the crank-connecting rod mechanisms are not the same and chosen so that The supporting part of the trajectory of all the shoes 8 approximately coincided. When the cranks are rotated, the 3 support shoes 8 with unequal intervals are lowered onto the support surface, therefore, the resonant oscillations of the housing are excluded. 3 il.

This invention relates to a wheeled propulsion system.

The purpose of the invention is to eliminate the resonant vibrations of the body.

Fig. 1 shows the kinematic scheme of the walking wheel with the trajectories of the hinges of the support shoes: Fig 2, a wheel, a general view; in fig. 3 is a section A - A in FIG. 2

The walking wheel includes a housing 1 on which rigidly interconnected cranks 3 are mounted with the possibility of rotation on a rigidly attached axle 2, the gear wheel 4 attached to them is set in motion. At the ends of the cranks 3, unequal four-curvature-connecting rod are mounted around the ends of the cranks 3

mechanisms. The connecting rods 5 of these mechanisms are attached by hinges 6 to cranks 3, at the optimally selected point of connecting rods 5 by hinges 1 supporting shoes 8 are attached, and one ends of the rockers 9 by hinges 10 are connected to connecting rods 5, and others are fixed by hinges 11 to axis 12. Axis 12 is rigidly attached to The cheek 13 is located inside the circumference of the hinges 6. The dimensions of the cranks 3 are different, as are the links of the same link of all four-link bars. These dimensions are chosen so that the trajectories 14 and 15 of all the shoes 8 on the straightline linear section coincide.

The wheel works as follows.

When the cranks rotate, the 3 support shoes 8, due to the optimally selected lengths of the four-link units, make closed trajectories 14 and 15 and merge into one trajectory in an approximately straight line section, where the ground 1 is successively meeting the ground, depending on the direction of rotation. When turning off the rotational drive, the wheel can also be used as a follower.

Since this wheel has a different bearing change time, the probability of occurrence of resonance phenomena is sharply reduced.
