The method of assembly of an articulated vehicle
(57) Abstract:Usage: refers to the transport machinery. The inventive method of Assembly of the articulated vehicle 1 is that the front and rear In semi-frames are connected by means of the hinge 4 can be rotated relative to one another around a horizontal longitudinal axis 2. The drive shaft is passed through the inner hole of the hinge. Before installing the hinge find the area of intersection of the axis 2 of the vehicle and the axis of the propeller shaft and install the hinge in place. On Palermo power set 5 and the damping of 6 items, and have them at an angle towards each other and through these elements Rethimno-rigidly connect the frame parts together. 2 Il. The invention relates to a transport machine building.There is a method of Assembly of all-wheel drive vehicles for use on the road, namely, that the front and rear semi-frames are connected by means of hinge can be rotated relative to each other. The drive shaft when it is passed through the hinge.The disadvantage of this method is that the design is up strictly along the longitudinal axis. All loads are transmitted to the hinge and need to install a powerful bearing and powerful fasteners holding the bearing. In addition, the generated vehicle has limited movement on public roads.The problem solved by the invention, with minimal cost, a small number of service stations to convert any pageprivate or rear-wheel drive vehicle in the vehicle with superior handling characteristics for operation in two modes: off-road and on public roads with the possibility of safe movement on recent average rate of the total flow of vehicles.This object is achieved in that the front and rear semi-frames are connected by means of hinge can be rotated relative to each other around a horizontal longitudinal axis, and the drive shaft is passed inside the hinge. The inner bore of the hinge perform commensurate with the magnitude of the propeller shaft runout. Before installing the hinge find the area of intersection of the longitudinal axis of the vehicle and the axis of the propeller shaft and the cops, and have them at an angle towards each other and through these elements Rethimno-rigidly connect the frame parts between themselves and form a skeleton of the L-shaped profile.In Fig. 1 shows a top view of the collected vehicle; Fig. 2 is a side view collect the vehicle.The method is as follows.The vehicle 1 is placed on a special platform and either visually or by using conventional measuring instruments is determined by the area of intersection of the longitudinal axis 2 of the vehicle with the axis of the propeller shaft 3. Then the front and rear semi-frames B of the vehicle through a hinge 4 are connected. The hinge 4 is installed at the intersection of the longitudinal axis 2 and axis 3 of the propeller shaft. The drive shaft is passed inside the hinge. On the front and rear Palermo firmly establish the power of the 5 elements. At the same time placed them towards each other. Then the front and rear semi-frames are connected by means of the mentioned power elements. Between pournami also set the damping elements 6, the upper ends of which are fixed to the upper part of the power elements in the first semi-frames, and the lower ends of which is the front and rear semiframes by installing between the horizontal hinge, through the inner hole which transmit the drive shaft, characterized in that before installing the hinge determine the intersection of the longitudinal axis of the vehicle and the axis of the propeller shaft for installation in this location of the hinge, then on the front and rear Palermo install power components, inclining them towards each other and connecting in the upper parts of each other with the possibility of separation, and the lower part of each power element rigidly connected with the respective pournami, then between pournami in a vertical transverse plane set the cylinders, the upper ends of which are fixed to the upper part of the power elements in the first semi-frames, and the lower ends of which are fixed to the second end.

Angle between projections for rear wheels differs from zero. At second mode, center of rotation is on longitudinal axis of projection onto supporting surface of longitudinal plane of symmetry of vehicle and is spaced from vertical plane of rotation of front wheel by distance L defined by interval of from L=0.1H to L=0.9H, where H is wheel base.
