Abstract

Compressed air hoses and hydraulic hoses (33, 34) for actuating various devices on a trailer are automatically coupled together since the tractor (11) and the trailer (13) have two corresponding valve blocks (30, 25) with corresponding valves and the valve block (30) of the tractor is moved against the valve block (25) of the trailer. The valve block (25) of the trailer is turnable and it has the same axis of turning as the trailer on the tractor. Means (50, 51) arranged in connection with the valve block (30) of the tractor is arranged to turn the valve block (25) of the trailer right and to guide the valve blocks before their valves (55, 56) are coupled.

Description

Coupling device
This invention relates to a coupling device for a number of fluidum hoses between a traction vehicle and a trailer.
Particularly within an industrial site with short internal transports, the coupling and uncoupling of semi-trailers may be frequent and it is desirable that the various hydraulic and pneumatic hoses simply and quickly can be coupled and uncoupled.
It is an object of the invention to provide for a safe and reliable coupling device that can be controlled from the cab of the traction vehichle.
The invention will be described with reference to the accompanying drawing that show an embodiment of the invention.
Fig 1 shows fragmentarily in a side-view certain parts of a traction vehicle to which a semi-trailer is coupled and it shows a coupling device for a plurality of fluidum hoses in accordance with the invention.
Fig 2 is a top-view corresponding to Fig 1.
Fig 3 is a side-view at a larger scale and partly in section of the coupling device shown in Fig 1.
Fig 4 is a top-view corresponding to Fig 3.
Fig 5 is a side section through a coupling member shown in Fig 2.
Fig 1 shows fragmentarily a traction vehicle 1 1. It has a so called fifth wheel 12. A trailer in the form of a semi-trailer 13 is also shown. It has two beams 14, 15 connected by means of two I-beams 16, 17 and a plate 18. The plate 18 carries a kingpin 19 that mates with the fifth wheel 12. The axis I of the kingpin is the turning axis of the trailer on the tractor. This is the conventional technique for coupling a semi-trailer to a tractor and it is therefore not described in closer detail. The coupling and uncoupling operations are controlled from the tractor cab. A valve block 25 with a stub shaft 26 (Fig 5) is mounted on the trailer so that it is turnable about the axis of the stub shaft 26 which axis coincides with the axis I of the kingpin 19. A spring 27 (Figure 5) is arranged to maintain the valve block forward directed. An arm 28 is mounted on the tractor so that it is pivotable in a vertical plane about an axis II by means of a motor 29.
A valve block 30 is mounted on the arm 28. The valve blocks 25, 30 contain a number of hose-connected valves that are coupled together in pairs and opened when they are moved against one another. There is a hose bundle 33 coupled to the valve block 25 of the trailer and a hose bundle 34 coupled to the valve block 30 of the tractor. The hoses can be compressed air hoses for the air brakes of the trailer and hydraulic hoses for example for maneovering of the dumping, of the protective covers over the load, and the like, depending on which type of load the trailer is adapted to carry.
The Figures 3 and 4 show in more detail the mounting on the arm 28 of the valve block 30 of the tractor. The outer part of the arm has a support plate 35. A short guiding beam 36 with rectangular cross section is mounted on the support plate 35 by means of mounts 37, 38 so that it will be axially slidable on the support plate. The valve block 30 has four sliding blocks 39 - 42 at its front and four rear sliding blocks 43 - 46 by which it is slidably guided in the guiding beam 36. A gas spring 47 is coupled between the guiding beam 36 and the valve block 30 and it strives to move the guiding beam 36 forwardly relative to the valve block 30 into the end position in which the guiding beam 36 is shown in Figures 3 and 4. A hydraulic cylinder 48 is coupled between a support 49 on the arm 28 and the valve block 30. The guiding beam 36 encompasses the valve block 30 and protects it.
When the tractor and the trailer have been mechanically coupled together, the arm 28 is pivoted down from an upright position to the position shown in Figure 3. By means of the hydraulic cylinder 48, the valve block 30 of the tractor is moved forwardly towards the valve block 25 of the trailer. The front edge 50 of the guiding beam 36 will engage with a corresponding surface 51 on the valve block 25 of the trailer so that the valve block 25 turns into coaxiality with the valve block 30. Thus, the guiding beam 36 takes support against the valve block 25 while the valve block 30 proceeds forwardly against the action of the gas spring 47 so that two guiding pins 52 with conical ends are guided into corresponding holes 53 of the valve block 28 and make a fine adjustment of the relative positions between the valve blocks before the valves of the valve blocks are coupled together in pairs. The valves 54 of the tractor have extending cylindrical ends 55 (only one valve is denoted) that fits in and seal against corresponding bores 56 in the valves 57 (only one valve is denoted). The two cooperating valves 54, 57 open automatically when they are coupled together and close automatically when uncoupled. The valves are conventional and are not described in detail.
