The present invention relates to the field of trackless vehicles and can be used in the design of the trains.
Known combination consisting of the towing vehicle Volvo-F89-32 and semitrailer (see Quick automotive Handbook 10th ed., revised and enlarged extra - M.: Transport, 1983, page ie cars, coming from a significantly greater rate than the train, and behind the train, hurrying after him, and especially at night, facing aft part of the trailer. When this shock from the car is so significant that the safety bar, located in the aft part of the frame of the trailer, is destroyed, and the car is under the frame and body of the trailer. This entry entails cut the upper part of the body of the car, and its people instantly die, and components and parts of the rear part of the trailer cannot be restored.
Also known combination along.with. The USSR №1139655, consisting of the towing vehicle and semitrailer whose trolley mounted for movement along the longitudinal axis of its frame. However, in case of collision following the train of cars at the stern of the semi-trailer is not excluded, as in the analogue section of upper part of the body, and hence the death of the passengers and the driver of the car. At the same time, as a result of this collision and, therefore, deformation of the bearing structures of the frame and body of the semitrailer past cannot be restored.
Therefore, the aim of the present invention vlaovic car under the frame and body of the trailer, the moving part of the automotive trains.
This objective is achieved in that the end part of the frame of the trailer, made inclined in the direction of the towing vehicle, provided with a reference sheet on this site, and it guides movably in the longitudinal plane of the trailer and contacting with the supporting sheet, placed the base plate, pivotally interconnected with bracket rigidly mounted on the frame of the truck, the latter being biased by compression spring with respect to the frame of the semitrailer, and the safety beam rigidly mounted on said truck frame.
In the drawings, Fig.1 shows a General view of the trailer during the approach of the car, Fig.2 - General view of the combination after the collision of a car with a semi-trailer of Fig.3 - view the trailer back in cross section and in Fig.4 - node interaction of the spring with the leader of the frame of the trailer.
The rig consists of a truck tractor with 1 semitrailer unit 2, on which is placed a frame 3 trailer 4. In the back of the frame 3 is the reference sheet 5, contacthouses with base plate 6, which by means of finger 7 pivotally mounted on the bracket 8 of the bogie frame 9. On the frame of the trolley 9 is rigidly fixed safety br the bracket 8, and napraviteley 13, rigidly fixed on the frame 3 of the trailer 4. On the frame 3 trailer 4 is fixed limiter 14 trolley 9 and with safety beam 10 is in contact passenger car 15.
Works in combination as follows. In the process of moving trains in the direction of arrow b (see Fig.1) his trailer 4 is in position, when the carriage 9 is located in the rightmost position and the base plate 6 rested the stopper 14 of the frame 3 trailer 4. This spring 12 with a certain predetermined force acting on the bracket 8, and, therefore, the support plate 6 through the finger 7, which creates a fixed position of the trolley 9 on the frame 3. When the car 15 for a number of reasons (for example, the driver fell asleep, lost control, slammed on the brakes of the train, and so on) at a considerable speed catches up with the train and hits the safety beam 10 truck 9 (see Fig.2), the latter moves with acceleration in the direction of the arrow In, clawing across the support plate 6 plate 5 of the frame 3 trailer 4 and compresses the spring 12. Depending on the magnitude of a shock last will be limited by the speed of the truck 9 in the direction of the arrow B, while dampfi the reference sheet 5, and also overcome their own weight of the semitrailer 4, which acts on the carriage 9 in the direction of arrow C. as the frame 3 trailer 4 at its rear end has an inclined surface, when the carriage 9 in the direction of the arrow In the same time and the angular rotation of the semi-trailer 4 by the arrow D on the fifth device 2 of the towing vehicle 1, and it further excludes the interaction of the upper body of the passenger car 15 with 4 trailer that will protect against injury to people in it. After investigating the accident, the train is moved by the arrow In, and under the action of the compressed spring 12, the carriage 9 is returned to its original position and transport position, such as that shown in Fig.1. If such return is not happening, you could stop and truck wheels 9 and moving the vehicle 1 by the arrow B, it is possible to achieve a movement of the reference sheet 5 relative to the base plate 6, and the trailer 4 and the carriage 9 will occupy the position shown in Fig.1.
Feasibility advantage of the proposed technical solution is obvious, as it will allow, first, to reduce the probability of death of persons in a motor vehicle, when the collision with the train and, secondly, eliminate breakage dealt to improve the safety and reliability of the trains.
The combination consisting of the towing vehicle with a fifth wheel device, interacting with a semi-trailer containing a body mounted on a frame provided at its end with a safety beam, supported on a cart that can move in the longitudinal plane of the frame, characterized in that the end part of the frame of the trailer is made inclined in the direction of the towing vehicle, provided with a reference sheet on this site and in its guides movably in the longitudinal plane of the trailer and contacting with the supporting sheet, placed the base plate, pivotally interconnected with bracket rigidly mounted on the frame of the truck, the latter are biased by compression spring with respect to the frame of the semitrailer, and the safety beam rigidly mounted on said truck frame.
