RU208123U1 - DEVICE FOR INCREASING THE REFERENCE CAPACITY OF TRACKED MACHINES FOR MOVING ON SOIL WITH LOW CARRYING CAPACITY - Google Patents

Abstract

The utility model relates to the field of military technology, in particular to devices for increasing the ground clearance of military tracked vehicles. To achieve this goal, a device is proposed, consisting of a track with a rubber-metal hinge, a return spring, a petal and a hinge. The petal, designed to increase the bearing surface of the tracks of the caterpillar, is a rectangular metal plate and is made of steel, which is attached to the treadmill of the track with a hinge and a return spring installed in the vertical drilling of the adjacent track to ensure the mobility of the petal. Thus, the proposed technical the solution increases the bearing surface by reducing the average specific pressure on the ground at the junctions of consecutive tracks when the machine is moving on soils with low bearing capacity.

Description

The utility model relates to the field of military technology, in particular, to devices for increasing the support cross-country ability of military tracked vehicles (hereinafter referred to as VGM).

There is a known device for overcoming VGM road sections with low capacity (RF patent No. 2438090, published on December 27, 2011), in which the chassis is equipped with an additional removable platform with rollers and caterpillars, fastened with a fastener fixedly to the machine so that when the machine is turned on the reverse gear course, the platform with the machine moves forward on the ground.

In addition, there is a known device for increasing the support permeability of the VGM (RF patent No. 2438091, published on December 27, 2011), which consists in the following: to increase the permeability on soils with low bearing capacity, the VGM undercarriage is equipped with additional road wheels with tracks that are attached to the support rollers, move them with the main chassis, moving the VGM body along the ground.

As a prototype, a device for increasing the fifth wheel cross-country ability of military tracked vehicles (RF patent for utility model No. 157568, published on December 10, 2015) was taken, where the track chain is equipped with a device for increasing the adhesion of the track chain, which are additional automatically folded lugs, each from a stop designed for engaging with the ground and unfolding the lug, and a return spring attached to the track pin.

Known devices for increasing the support permeability of the VGM allow to reduce the average specific pressure of the VGM on the ground, to increase its permeability when driving on soils with low bearing capacity (wetlands, deep snow cover, etc.). However, these devices have a number of disadvantages:

- additional equipment of the VGM increases its total mass, which also leads to an increase in the average specific pressure on the ground;

- limits the area of the terrain, does not allow to sufficiently increase the proportion of the terrain area that is available for tracked vehicles, which leads to the need to avoid obstacles and increase the time to overcome them.

The aim of the proposed technical solution is to eliminate the shortcomings in the above devices.

To achieve this goal, a device is proposed (Fig. 1), which is made in the form of a petal 4, which is a rectangular metal plate made of steel, the front part of which is attached by means of a hinge 6 to the treadmill of the track 1, and the rear part is attached using a return spring 3 in vertical drilling of an adjacent track, while the petal is configured to descend onto an adjacent track at the mating points of adjacent rubber-metal hinges 2 when the support roller 5 hits it and to rise under the action of a vertically installed spring to its original state when the support roller leaves it.

An example of how the device works. When a VGM with a low bearing capacity moves on soils 7, the caterpillar track and track rollers 5 rotate. The track roller 5, rolling onto the track 1, transfers the force of gravity from the machine body, when the track roller 5 hits the petal 4, the latter descends, turning on hinge 6 with a return spring 3 and connects two consecutive tracks and prevents the rubber-metal hinge 2 from turning while increasing the supporting surface of the track at the junction of two adjacent tracks. When leaving the petal 4 of the support roller 5, the petal under the action of the return spring 3 installed in the vertical drilling of the adjacent track returns to its original position.

The proposed device allows automatically, when the tracked vehicle is moving, to increase the supporting surface, reducing the average specific pressure on the ground at the junction of successive tracks when the vehicle moves on soils with low bearing capacity.
