The technical field TO WHICH the INVENTION RELATES

The present invention relates to a protective device for articulated vehicles containing at least first and second parts of the vehicle, the adjusting mechanism connected with the corresponding part of the vehicle, and a drive element for changing the position of the vehicle parts relative to each other by means of the adjusting mechanism. The invention also relates to a method of controlling a rigidity means of such a protective device.

Art

There are articulated tracked vehicles that have front and rear portions of the vehicle, which are connected together in an adjustable manner by means of the adjusting mechanism. The vehicle comprises one or more drive motors via a power transmission provide the power distribution from the engine or engines on the respective tracks of the vehicle.

In document WO-A1-00/35735 shows an adjusting mechanism for connecting the first and second parts of the vehicle as provided in articulated vehicle. The adjusting mechanism contains two control link to�e is pivotally connected with each other by means of an adjustable connection. The adjusting mechanism further comprises two adjusting cylinder, which is the change in the position of the two vehicle parts relative to each other for changing the direction of movement of the vehicle. The adjusting mechanism also includes two hydraulic cylinder-piston mechanism, which is made with the configuration, such combinations which can withstand the pressure power cylinders and hydraulic shock absorbers designed for damping of the oscillations of parts of the vehicle in a vertical direction relative to each other during transport and, if necessary, for example, for lifting and rotating parts of the vehicle to the desired angle up to move over the obstacle.

When the articulated vehicle of the above type are subject to external influence, such as the explosion of the mines, it causes the displacement/movement of parts of the vehicle. This movement reaches the speed and acceleration, which is proportional to the weight of the vehicle. When the vehicle is subjected to a detonation/explosion, impact force on the vehicle and the personnel inside the vehicle, has two phases. The first phase occurs when the battery explosion�tsya, and lasts for a few milliseconds. After that, the pressure wave propagates from the charge and direction of the vehicle, after which the high pressure from the pressure wave exerts impact force on the vehicle. The vehicle is deformed under pressure from the pressure wave, and the magnitude of deformation depends on the design and frame of the vehicle and the distance to the charge and position of the charge relative to the vehicle. The movement of the vehicle during the first phase is small and may be only a few millimeters. However, the vehicle acquires the acceleration and velocity directed away from the explosion. The personnel inside the vehicle, it can injure parts of the body, which are close to those parts of the vehicle or in contact with those parts of vehicles that are deformed. In addition, the increase in pressure that occurs inside the vehicle due to an explosion, causing injury to personnel inside the vehicle.

The second phase begins as soon as the vehicle reaches the initial speed with great acceleration and will make a small displacement during the phase of detonation/explosion, and ends, to�Yes, the vehicle slows down and stops. This phase often involves large displacements of the vehicle that causes the vehicle can be thrown back several meters. When the vehicle moves, the personnel inside the facility, and can be injured/wounded.

Since the magnitude of the acceleration, velocity and displacement of the vehicle in the event of an explosion, proportional to the weight of the vehicle, it is desirable to use the entire weight of the vehicle when it is exposed to the explosion. However, in the case of an articulated vehicle the entire weight of the vehicle when the explosion is not used, since the adjustment mechanism functions as a pivoting of the connecting link between parts of the vehicle.

Object of the INVENTION

One object of the present invention is to develop an articulated vehicle having a better protection for personnel inside the vehicle.

An additional object of the present invention is to develop an articulated vehicle in which the entire weight of the vehicle is used to reduce the impact on the vehicle and the personnel in case of an explosion.

Disclosure of the INVENTION

The aforementioned problems are solved by the protective device according to paragraph 1 of the formula of the invention and the method according to paragraph 13 of the claims.

In this protective device, the mass of both the front and the rear of the vehicle is to be used when acceleration and/or speed of at least one of the parts of the vehicle exceeds a preset limit value, which occurs when the vehicle is subjected to external influence, such as a mine explosion. When the relative position of each corresponding part of the vehicle will be fixed relative to other parts, the design of the vehicle becomes more rigid, resulting in the displacement caused by explosion, is reduced, and the impact on personnel inside the vehicle is reduced.

In accordance with one variant of the invention which add rigidity to the tool is a valve, which is connected with a drive element by means of a fluid circuit, the valve restricts the inflow and outflow of fluid, administering a drive element, so that the drive element is fixed in a rigid or nearly rigid position. When the drive element is fixed in �harddisk-images position the position of each corresponding part of the vehicle will be fixed relative to each other. Drive element may be a hydraulic or pneumatic cylinder, which is arranged to control the direction of movement of the vehicle by means of inflow and outflow of fluid, administering a drive element in the fluid circuit that is connected to a drive element. Drive element may also be a hydraulic or pneumatic damper, which is made with the possibility of damping and adjusting the position of the vehicle parts relative to each other by means of inflow and outflow of fluid, administering a drive element in the fluid circuit that is connected to a drive element.

In accordance with an additional variant of the implementation of a rigidity tool is a strap attached between parts of the vehicle, wherein the belt is translated in the strained state for fixing the position of each corresponding part of the vehicle relative to each other. This strap is easy to attach between the parts of the vehicle.

In accordance with another variant of implementation which add rigidity to the tool is a mechanism that blocks�morning, located between the parts of the vehicle, wherein the locking mechanism is moved to the locked position for fixing the position of each corresponding part of the vehicle relative to each other.

The caterpillar and the locking mechanism can be actuated by a centrifugal clutch when exceeding predetermined limit values. At least one end of the caterpillar is wound on the drum, which rotates when a tensile force acts on the caterpillar. The centrifugal clutch is located on the drum and locks the drum against further rotation when moving the caterpillars caused the explosion, causing the exceedance of a given frequency of rotation of the drum. In an alternative embodiment, the caterpillar and the locking mechanism can be actuated power element when exceeding predetermined limit values. Force element may be a hydraulic, pneumatic, or electric driven gun smoke drive, which is driven by a control device when exceeding predetermined limit values.
