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 (see the book M.M. Shchukin. Hitch cars and trucks. The motor cycle " M-L., 1961, p.50, Fig). From the towing vehicle to the frame of the unit installed anchor hitch (truck unit), interacting saddle with a support sheet of the 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 reference device, which represents 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 a work is in the area 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 in the patent RU No. 2230682 C1, which,like the previous one, consists of the towing vehicle and the trailer, but in contrast, has a drive support device, eliminating the manual labour man at the technological operations of coupling or rascepa links trains. This drive is effected by rotation of the bolt, which is articulated through the circuit causes the rotation of the screw posts. However, this device does not preclude the possibility of injury to operating personnel, as the latter is forced to manually produce and other operations, such as connection pnevmotormoznyh systems and electrical systems of the towing vehicle and semi-trailer and so on, and so people find themselves again in a hazardous area under the trailer or between him and the car-truck, which is very unsafe.

Therefore, the aim of the invention is to improve working conditions for maintenance of trains at the time of coupling or rascepa its parts.

This objective is achieved in that the splined shaft is made hollow and with one hand through pneumatologie device connected to pnevmotormoznyh system of the towing vehicle, and the other equipped with ball shut-off valve can be used to communicate with the response, located in the axial through channel made in turning the bolt, and the said channel at the opposite end of the bolt through another pnevmopodem the developing device interconnected with pnevmotormoznyh system of the trailer.

Figure 1 shows a General view of a combination in rosapenna condition figure 2 - cross 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, figure 3 is a kinematic diagram of the drive control of the supporting struts of the trailer and figure 4 is an enlarged node parts truck of the device in section.

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 swivel bearing 7, 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 8 of the seat 11, as is the case in designs and analog prototype. In the saddle device 3 adjustably mounted toothed sleeve 13 with the annular collar 14 that interacts with the fork 15 of its control by means of the lever 16. Gear sleeve 13 is rigidly connected to 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 reference to Asami 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 bolt 8 is made channel, equipped with ball shut-off valve 29 on the one hand and on the other hand pneumopathies device 30 attached to pnevmotormoznyh system 31 of the semi-trailer. The spline shaft 17 is also made hollow channel 32, equipped with ball shut-off valve 33, and the gear sleeve 13 has a sealing element 34. On the other end of the spline shaft 17 is fixed pneumatologie device 35 that is attached to pnevmotormoznyh system 36 of the towing vehicle.

Works in combination as follows. For coupling of the towing vehicle 1 with trailer 6 it is served on the arrow And back up until the pin 8 together with the gear 10 will not enter the truck device and will not take a position in it, as shown in figure 2. After this well-known method, as it is used in the analog, close the lock 12, which secures the bolt 8, and hence the semitrailer 6 relative to the towing vehicle 1. At this point in time, between the support sheet 4 and the seat 11 has a small gap (not shown) of the order of 8-10 mm, then manually turn the lever 16 in the direction of arrow b (see figure 3), which contributes moved the Yu in direction of the arrow C, with a fork 15, the toothed sleeve 13 (actuator lever 16 with the plug 15 can be mechanized, for example, using hydro or pneumatic cylinder, which is operated by the driver from the cab of the tractor 1). Such a toothed sleeve 13 causes the gear 10 bolt 8 is included with it in the engaged position, as shown in figure 4. Further movement of the toothed sleeve 13 is produced until the drawing figure 4 shows only the intermediate gear 10 and the gear sleeve 13 until the ball check valve 29 will not come into contact with ball shut-off valve 33, which, sinking each other in the direction of arrow D will provide the connection pnevmotormoznyh systems 31 of the semi-trailer and 36 of the towing vehicle. Then the lever 16 is fixed is widely known in the art methods. The tightness of the connection channels shut-off valve 29 and 32 will provide a sealing element 34, which will also be elastically deformed by the gear 10. Therefore, the channel shut-off valve 29 and pnevmotormoznyh system 31 of the semi-trailer will be under pressure compressed air (pneumatic brakes of the trailer are widely known practice, and therefore these materials are not considered), coming from a source of compressed air under the car tractor 1. Then use the drive device 18 produces rotation were is avago shaft 17, consequently, the toothed sleeve 13 (they are hard linked), which transmits the rotation from the gear 10, the bolt 8 and the sprocket 9. Since last using the adjustable circuit 19 is connected to the sprocket 20, they transmit the torque of the screws 21, which, turning in the nut 23, provide movement along arrow E of racks 24, thereby eliminating the contact supporting wheels 25 with the ground. As soon as the gap between the supporting wheels 25 and the ground reaches a certain value, excluding contact them with the roughness of the roadway, the transfer torque on the spline shaft 17 stop and the train is ready to move. It should be noted that the clutch gear 10 and the gear sleeve 13 is constant, since it is necessary condition for the pair of channels shut-off valve 29 and 32. At the same time, to avoid damage of this site, due to the possible angular movement of the trailer in the longitudinal planes trains, for example, by the arrow G (Fig 2), in the supporting sheet 4 trailer posted swivel bearing 7. Rescap trains produce similar to that described above only in reverse order, while only 24 hours touches the ground, pnevmotormoznyh system 31 and 36 dismantled by overlap-ball shut-off valves 29 and 33 of their channels, thereby eliminating their messages with Atmos is a hero.

Feasibility advantage of the proposed solution in comparison with the known obvious, since it allows to improve the working conditions of people employed in work connected with the coupling and razepam links trains due to the mechanization of this process.

The rig contains a truck-tractor with semitrailer device and the semi-trailer body and the support device, is provided in its front part a ledge with a support sheet bearing swivel pin contact through gearing with the driven bushing fixed on the splined shaft associated with the drive of rotation, characterized in that the splined shaft is made hollow and with one hand through pneumatologie device connected to pnevmotormoznyh system of the towing vehicle, and the other equipped with ball shut-off valve can be used to communicate with the response, located in the axial through-passage in the rotary bolt, and mentioned the channel at the opposite end of the bolt through another pneumatologie device interconnected with pnevmotormoznyh system of the trailer.
