The invention relates to the production of vehicles, namely versatile vehicle capable of movement in different environments, in particular, on water and river rapids, snow, ice, swamp, sand, etc.,At the present time, in connection with the development of sparsely populated areas with missing transport communication system, there is an urgent need to develop a versatile vehicle capable of movement in various natural environments. Universal vehicle must simultaneously satisfy several conflicting technical requirements, in particular, to move with high speeds (60-100 km/h) in heterogeneous environments, without any setups device cross border environments, to overcome on the way different low (30-50 cm) obstacles, such as rocks, logs, rapids, rivers, etc.,You know the bottom of the case glicirama amphibians, made flat, smooth and hard (the tion of the vehicle, appearing during its movement on uneven surfaces or when driving over bumps. The resulting deformation creates significant stress that can lead to the destruction of the bottom.In addition, the bottom should be rigid enough that it requires structural reinforcement, and hence the weight of the entire vehicle, which in turn implies an increase of the engine power, specific fuel consumption, etc.,You know the bottom of the case glicirama amphibians (see and.with. SU 759390, CL 63 In 1/22, B 60 F 3/00, 1976), containing a shock-absorbing flexible part of the bottom of the hull, symmetric with respect to the median plane and secured to its front transverse edge can be rotated relative to the hinge on the fixed part, and between the fixed and movable part of the bottom placed elastic air bellows and the movable part of the bottom forms a movable transverse step and paired flush with the contours of the fixed part in pressed to her position. In addition, the movable part of the bottom is made in the form of a V-shaped cross-section of the plate, the stationary part of the bottom of the housing is fitted with a transverse step, which is transverse hinge rotation of the movable h edge of the movable part forming a longitudinal step.The main disadvantage of the bottom of the vehicle are its low damping properties, leading to significant congestion when driving on uneven land, because cushioning the movable part with the air bellows is installed only on the forward part of the fixed bottom surface, which being in contact with the feed part, perceives directly impacts when moving over uneven land.You know the bottom of the case glicirama amphibians, taken as a prototype, including a stationary part of the housing and fixed thereto laterally movable portion of the housing in the form of thrust at each other flexible transverse stripes, and located between the shock-absorbing elements in the form of air bellows (see patent US 6003465, CL 63 In 1/00, 63 In 1/22, 1999). Due to the presence of flexible transverse bands, allowing flexible deformation of the movable part and the shock-absorbing elements can be efficiently absorb the impact energy of the surface arising from the meeting with the bump or hit a small obstacle.However, alongside the advantages, there are technical decision has serious shortcomings. First, the execution of the movable part in the form of his friend, the t is often necessary when moving in a confined space.Secondly, when a vertical or horizontal sliding stroke of the vehicle body about the obstacle, flexible strips curving transmit significant pulling effort on the stationary part of the housing, in some cases even leading to the separation of the bands.Thirdly, the known design of the movable part of the body has low maintainability in the field, which practically prevents further operation of the vehicle in case of failure of one of the flexible transverse stripes.Fourthly, a vehicle equipped with a known bottom, the yaw movement, due to a lack of longitudinal stabilizing elements.The problem to be solved in the present invention, is the exception mentioned disadvantages and aims to create the bottom of the hull versatile vehicle capable of moving both backward and forward, eliminating yaw movement, the damping resulting significant shock loads and high maintainability in the field.The task in the bottom of the case of the universal vehicle, comprising a stationary part cigaette fact, that the movable part of the body made in the form of nonwoven fabric formed of longitudinal members, fastened transverse threads.The specified implementation of the bottom of the case allows you to create due to the non-woven cloth of the longitudinal elements, fastened together by transverse threads are very durable and flexible shell, protects the shock-absorbing elements from the adverse effects of the surrounding objects (stones, sand, ice hummocks and so on).It is advisable to select gaps between the longitudinal elements and pressing the flexible membrane to the damping elements of the non-woven fabric mounted on the lateral parts of the body with preload, using as a cross-thread steel solid or stranded cables. Solid steel cables to dampen shock loads can be secured through an intermediate damping elements, for example, rubber washers, and a multi-strand steel cables by twisting lived in the process of weaving, have the ability to "stretch" when the load increases and "shrink", when it is removed.Profitable as longitudinal members to use a flexible plastic tape, or specialized plastic tape, or stamataki. The use of the above longitudinal tapes, capable of providing high strength and flexibility of the movable part of the body, without creating significant tear efforts on the stationary part of the housing, and the use of longitudinal tubular elements enables them to be used not only as a longitudinal steps, reducing the yaw movement, but also for blowing air when moving in water, which can significantly reduce water resistance when entering the planing, and thus to reduce the required power output or fuel consumption. With one or more longitudinal strips and/or tubular longitudinal members can be attached to the front portion of the chassis of the vehicle, which will significantly reduce lateral loads arising from the damping of the shocks arising from the movement of the vehicle. Since the front part of the non-woven cloth secured by one or more longitudinal elements with a fixed part, through the "window" is easy to provide free access to systems management and control of the air bellows, and the presence of a removable, protective lining that covers the non-woven fabric from the front of the case, poswe vehicle forward and back, back nonwovens to perform beyond the rear wall of the vehicle and set it to lift relative to the lower support surface of the vehicle.It is advisable to reduce resistance when moving through the water non-woven fabric to perform in the form of transverse steps formed partially overlap each other transverse slices flat non-woven cloth.Thus, the claimed invention allows to create simple and robust design of the bottom housing of the universal vehicle for rapid movement through the water, swamps, sand, snow, ice, etc. that is unique among the known vehicles, and therefore meets the criterion of "inventive step".In Fig. 1-5 are drawings explaining claimed the bottom of the case of the universal vehicle.In Fig.1, a and b schematic representation of the proposed bottom, consisting of a fixed part of the housing 1, a shock-absorbing element 2 (e.g., air bellows), the movable part of the housing 3 made in the form of nonwoven fabric formed of longitudinal members 4, bonded cross the funds.In Fig. 2, a, b, and in the present version of the proposed bottom, ensuring the smooth back of the vehicle. The vehicle is equipped with a raised heel, consisting of a rigid frame 6 attached thereto by means of wires 7 of the longitudinal members 4, between which and a rigid frame 6 are shock absorbing elements 2. The backdrop connected with a fixed part of the housing with a hinge 8 and the lifting mechanism 9 (for example, in the form of a hydraulic cylinder).In Fig.3, a and b shows a variant of the proposed bottom, the movable part of which is made in the form of transverse steps 10 and with the fore part of the vehicle is covered with protective plate 11.In Fig. 4 presents a cross-section of the vehicle with the proposed plate, the movable part of which is made as a combination of longitudinal strips 4 with a longitudinal tubular elements 12 (callout), and also shown in callout B In the ways of fastening the transverse threads on the fixed part of the case: B - fixing thread 5 (thread - multi-conductor cable) to the mounting element 13 (area) by the end of the sleeve 14 with the locking bolt 15, the washer 16 and the elastic element 17; the fixing thread 5 (thread - wire) to the mounting element 13 (the submitted cross-section of the vehicle with the proposed bottom, the movable part of which is made of flexible plastic or composite of bands 4, connected by a thread 5 (callout a), of a flexible plastic profile strips (callout b) or metal strips (callout).Declare the underside of the vehicle operates as follows. When the vehicle (Fig.1) wavy surface, the shock load from the movable part of the housing 3 made in the form of a flexible non-woven cloth of the longitudinal elements 4 are fastened together by transverse threads 5 are transmitted to the shock absorbing elements 2, which absorb impacts arising blows. Due to the fact that the non-woven fabric composed of longitudinal stripes (Fig.5, a, b and C) or combinations thereof with a longitudinal tubular elements (Fig.4, node A), manages to create a very durable and flexible fabric having considerable effort to break that protects the cushioning elements 2 from destruction, and the vehicle body 1 from shock loads. If necessary, the vehicle is moving backward (Fig.2) the background using the lifting mechanism 9 rises to a certain angle relative to the surface on which the movement (Fig.2). When moving through the water back through mechanism 9 Panoramica longitudinal tubular elements 12 can significantly improve the directional stability of the vehicle and reduce its yaw, and execution rezannoy design non-woven cloth (Fig.3) are able to reduce the resistance when the vehicle is water.When failure (breakage) of one of the longitudinal members 4 non-woven cloth in the field have the ability to eliminate breakage due to complete removal of the defective element 4 and the shift in the transverse threads 5 in its place adjacent and subsequent longitudinal elements 4 by changing (reducing) preload damping elements 17.Thus, the claimed the bottom of the case allows you to create versatile vehicle capable of moving with high speed in various environments, such as water, snow, ice, marsh, sand, etc.
