Method of maneuvering the trailer
(57) Abstract:Use: for control of wheeled vehicles, in particular for the management of multi-tier units equipped with two-axis swivel trucks. The inventive execute moving parts 1 and 2 of the vehicle by the synchronous rotation of the cylinders in the horizontal and vertical planes defined groups of the front 4 or rear axle 5-axle swivel trucks relative to paired with the axes of the links. 4 Il. The invention relates to transport machinery, namely, to control the maneuver of the vehicle and its parts.Closest to the present invention is a method that allows you to change the direction of movement of the vehicle at any desired angle, and there is no question of the progressive movement. Pre-exercise lifting the front axle before rotation and after its sinking produce the rise of the middle axis, with subsequent rotation and lowering. Existing methods of maneuvering allow for alternate movement in a horizontal or vertical direction only one of the axes of the transport is causing a lot of effort and energy in the hydraulic drive vehicle. In addition, methods maneuver can only be used for vehicles of a certain line-up with articulated frame, which limits the scope of applicability of these methods. Known methods do not provide during the maneuver synchronous rotation of the set group axes relative to the associated links and not allow you to move the vehicle in the transverse direction.A method of shunting trains, each link of which is mounted on the front and rear axle swivel trucks, including changing the position of the parts without their longitudinal translational motion, so that the first synchronously raise the front or rear axis of each swivel truck, then turn each cart in a horizontal plane around the vertical axis passing through the center of mass is not lifted axis, then raised previously-axis is lowered.The proposed method of maneuvering can be made for vehicles with different types of layout units and hydraulic equipment. The frame of the vehicle can be made hard or have a swivel. The vehicle can be as simple, and many of the AZ-2000 ("Perestroika"), consisting of interchangeable modules and providing many options for the arrangement of modules depending on the operational goals.Turn two-axle trucks significantly reduces the need for horizontal movement of the wheel axes of the hydraulic power, as it does not require rotating parts of the vehicle together with the movable axes. This operation allows you to make synchronous rotation of the axle group that provides an opportunity not only to change the direction of movement of the parts of the vehicle, not doing translational motion, and to overcome certain obstacles (pits, ditches, some stones, logs, and so on), and to effect movement of the vehicle in the transverse direction.The essence of the method is illustrated on the example of a modular trailer MAZ-200 ("Perestroika").In Fig.1 shows the position of the wheel axis, the corresponding rectilinear movement of the vehicle; Fig.2 - the vertical movement of the front axles turning bogies of the vehicle; Fig.3 - the vertical movement of the rear axles pivoting bogies of the vehicle; Fig.4 - phase gorizontalnom the tailoring tool has two pivotally connected to the drawbar link 1,2, installed on biaxial rotary trolley 3. The front 4 and rear 5 wheel axis swivel trucks 3 is moved in the vertical plane of the cylinders 6, and in the horizontal plane by rotation of the bogies 3 cylinders 7. The last link 2 of the vehicle can be connected following segments, which are interconnected through the shaft and the hinge and managed the same way as previous parts.Driving a vehicle is as follows.When working in difficult operating conditions (in limited areas, rough terrain, lesnevich and mountain roads, and so on) there is a need to change the direction of movements of parts of the vehicle, not doing translational motion, or it moves in the transverse direction.For this purpose it is necessary to ensure the effective axes and parts of the vehicle in the horizontal plane with the least resistance. The objective is achieved through a phased hanging front and rear wheel axes swivel trucks with subsequent synchronous rotation trucks in a given direction. The method includes the following operas(see Fig.2) and rotate them by means of swivel trucks 3 and cylinders 7 relative to the rear axles 5 on angle1in the horizontal plane (see Fig.4) with the subsequent lowering. Then hang the rear wheel axis 5 (see Fig.3) and rotate them relative to the front axis 4 in a horizontal plane at an angle of2(see Fig.4). As a result of the operations units 1,2 vehicles synchronously moved in the transverse direction, respectively, at a distance of1and2. To achieve the initial position of the wheel axis relative to their links (see Fig.1) hang the front wheel axis (see Fig.2) and turn them in a horizontal plane at an angle of3(see Fig.4) with the subsequent lowering. As a result, the position of the vehicle will meet its rectilinear movement, and the total longitudinal travel will be
=1+2+3< / BR>If necessary, rotate the parts of the vehicle that is not making translational motion at a given angle, the above-mentioned operations are performed with respect to individual biaxial rotary trucks, resulting units are deployed relatively untapped in the operations of the swivel trucks at a given angle, and thus change the direction of movement of the vehicle.METHOD of MANEUVERING TRAINS, each link of which is mounted on the front and rear axle swivel trucks, including changing the position of the parts without their longitudinal translational motion, wherein the first synchronous raise the front or rear axis of each swivel truck, then turn each cart in a horizontal plane around the vertical axis passing through the center of mass is not lifted axis, then raised previously-axis is lowered.
