Combination

 

The invention relates to the field of trackless vehicles. The rig contains a truck-tractor with semitrailer device and the semi-trailer body, the abutment screw posts and frame. In front of his part of the frame is provided with a ledge with a support sheet and rigidly attached thereto by the bolt. The bolt is made rotatable about its vertical longitudinal axis of symmetry and on the one hand is connected with the sprocket, interacting via a hinged chain with two reciprocal rigidly mounted on the screw posts, and the other has teeth in contact with gear sleeve, provided with a mechanism for its control and is connected to drive its rotation. The technical result - the reduction of labor required for the installation of the semi-trailer in the off position and enhancing the security service of trains in operation. 3 Il.

The present invention relates to the field of trackless vehicles and can be used in the construction of trucks.

Known combination consisting of the towing vehicle and semitrailer (M. M. Shchukin. Hitch cars and trucks. - M.-L.: the motor cycle", 1961, page 50, Fig.42). Automobils reference sheet ledge of the frame of the semi-trailer king pin, which is fixed by a lock, which is driven by the lever control. On the frame of the trailer is the anchor device in the form of a rack supporting rollers, designed to lock the trailer in when separated from the tractor in a position which would further its coupling with the same or another vehicle-tractor. Such a device is usually done in the form of screw jacks driven manually. The translation support device from the transport position into the working position and Vice versa is a time-consuming operation and in practice quite unsafe, because the worker is in the zone of unstable equilibrium of the semi-trailer at the time of the dissolution of a combination, and this often leads to injuries of staff.

Also known combination consisting of the towing vehicle KAZ-608 or ZIL-131, mounted with semi-khlopkovogo TMZ-879 (see the Semi-truck car TMZ-879. Technical description and operating instructions. Tashkent tractor plant, 1976). In General, the design of the trailer (with the exception of two dump bodies) is similar to analog, and it includes support device done degenova of the invention is to improve working conditions for maintenance of road conditions by reducing the labor intensity and improve safety at the time of preparing the trailer and its dissolution.

This objective is achieved in that the pins are pivoted about its vertical longitudinal axis of symmetry and on the one hand is connected with the sprocket, interacting via a hinged chain with two reciprocal rigidly mounted on the screw posts, and the other has teeth in contact with gear sleeve, provided with a mechanism for its control and is connected to drive its rotation.

In Fig.1 shows a General view of the trailer of Fig.2 - section in the longitudinal plane of the trailer in the zone of contact of the fifth wheel device of the towing vehicle with a support sheet of the ledge of the frame of the trailer of Fig.3 shows the kinematic diagram of the drive control of the supporting struts of the trailer.

The rig consists of the towing vehicle 1, on the frame 2 which has the saddle device 3 attached to the support sheet 4 of the ledge of the frame 5 of the semitrailer 6. On the supporting sheet 4 has a bearing 7 in which is movably supports 8, provided with a sprocket 9 and gear 10. In the saddle 11 saddle device 3 posted by lock 12, excluding the output pin out of the saddle, as is the case in designs and analog prototype. In the saddle device 3 adjustably mounted toothed sleeve 13 with the ring is with the spline shaft 17, which is movably accommodated in the drive unit 18. Through the sprocket 9 is spanned articulated chain 19, covering the sprocket 20 fixed on the screws 21 support device 22 of the trailer 6. The screws 21 are interconnected with nuts 23, rigidly fixed to the racks 24, provided with supporting wheels 25, the rack 24 is placed movably in the guide 26 of the support device 22 fixed to the frame 27 of the semitrailer 6. The screws 21 are placed in the bearings 28, also mounted on the frame 27.

The combination works as follows.

In transport position the rig is in the form as shown in Fig.1, and such a situation is provided a reliable swivel saddle device 3 to pin 8 of the trailer due to the fixation of the castle is the last of 12 in the saddle 11. In order to realize rescap trains, rotate the lever 16 in the direction of arrow a, which facilitates the movement of the fork gear 15 of the sleeve 13 in the direction of arrow b and its engagement with the gear 10, and since it is rigidly connected with the pin 8, is provided and the rotation of the sprocket 9 which is articulated through the chain transmits torque to the sprocket 20, and they contribute to the rotation of the screws 21. Rotation of the screws 21 causes linear movement along arrow D of nuts 23, and mark run into the ground. As soon as the wheels 25 will come into contact with the ground, the supporting sheet 4 trailer 6 is detached from the seat 11 saddle device 3 of the tractor vehicle 1 by the arrow E, and when the gap between the support sheet 4 and the seat 11 will be, for example (it is installed constructively) equal to 10-20 mm, drive unit off and the lever 16 is transferred in the direction opposite to the arrow A. This rotation of the lever 16 will move the toothed sleeve 13 in the direction opposite to the arrow B, which provides an exemption from engagement with the gear 10. Then widely known in the art reception open lock 12, releasing the fixation in the saddle 11 pin 8.

After that, the vehicle 1 moves in the direction of arrow G, and the semitrailer 6 remains in the position where it rests on the rack 24, and not on the saddle device 3 of the towing vehicle 1, i.e., it is in an unusable state. The coupling of a trailer similar to the above only in reverse when the rolling of the tractor vehicle 1 under the semitrailer 6, it should only be noted that after the coupling of the semitrailer 6 of the tractor vehicle 1 will be carried out and the lock 12 is closed, it should withdraw from the engagement gear 10 bolt 8 so that, in the 24, and secondly, to protect from damage when maneuvering the trailer drive unit 18.

Feasibility advantage of the proposed technical solutions in comparison with known designs of trains obvious, since it allows to avoid manual labor in the formulation of the semi-trailer in the off state and to improve the safe operation of trains in operational conditions.
