Sweden-Sweden (SE) 7801556-7 e (71) (72) Alf Gunnar Lönn, Villa Lido, Skepparevägen, 6lL 00 Söderköping, Sweden-Sweden (SE) (7 **) Oy Jalo Ant-Wuorinen Ab. (5 * 0 Transport wagon for front-wheel drive and bogie-drawn vehicles with tracked vehicles and the use of this wagon when traveling on public roads

Bogie-driven vehicles with tracked tracks are not permitted on public roads. Removing and re-installing the tracks, especially in the case of chains common to the corresponding wheelsets of the bogie, is very time-consuming and cumbersome and has sometimes even led to serious injuries, such as broken arms. It is therefore desirable that the roller when transporting such vehicles on a public road be kept fully lifted off the road.

The invention relates to a transport trolley for this purpose.

What all previously known transport wagons have in common is that they require a separate towing vehicle.

One type of transport trolley is two-axle and equipped with two inter-axle reduced loading platforms. The disadvantage of such a transport wagon is the cumbersome loading and unloading of the vehicle 63699 being transported to and from the transport wagon, because due to the wheels of the transport wagon, these operations have to be performed in the transverse direction of the transport wagon. Due to its structure, such a transport wagon is relatively long, which makes it considerably more difficult to drive on narrow and winding roads.

Another transport wagon of this type is disclosed in DE-A-1,255,507 and is specifically intended for the transport of tracked vehicles. The transport wagon has two parallel and oblique loading platforms forming the driving bridge outside the opposite wheels of the transport wagon. Outside said wheels and partly in front of them, the transport carriage is provided with additional wheels to support the transport carriage. When driving the vehicle up onto the transport wagon, it comes to a level above the side wheels. Such a structure, of course, shortens the length of the carriage compared to the former and also facilitates the driving of the vehicle up to and from the carriage, but its disadvantage is that the vehicle stands above the side wheels during transport, so that the common center of gravity of the carriage and the vehicle is relatively high. driving on a winding and uneven road.

In addition, there is a type of transport wagon based on the fact that the bucket or the like of the vehicle or work machine to be transported is portable to the loading platform of the truck while the opposite end of the vehicle or work machine is portable to the transport wagon. Such a transport trailer comprises, for example, a single-axle trailer whose load platform can be pivoted about its wheel axle so as to form a drive bridge along which the vehicle or implement can be driven and to which it can be attached, after which the opposite end of the vehicle or implement can be lifted on its own truck's load platform. at the same time it is possible to turn the drive bridge back so that it again forms a loading platform. The disadvantage of this 63699 transport wagon is the unreasonably high emphasis.

NO patent publication 133 183 discloses a transport wagon for transporting a vehicle in a plane above the road surface. The transport trolley has a bogie with two pairs of wheels where the wheels of the second pair of wheels are located axially inside the wheels of the second pair of wheels. The bogie has a carrier between both pairs of wheels, comprising a transverse frame through which the device for securing the vehicle to the transport carriage is passed. The fastening device may, for example, consist of a chain with a fastening hook connected to the tensioning device, by means of which the vehicle can be lifted onto the transport trolley at the same time. The carrying and securing devices of this transport wagon have made it possible to reduce the center of gravity of the vehicle combination, but coupling and lifting the transported vehicle to the transport wagon is relatively cumbersome and requires great care and, as mentioned earlier, requires a separate towing vehicle.

The present invention also solves the latter problems by constructing a transport carriage according to the features expressed in the appended claims.

The invention is illustrated by the accompanying drawings, in which Figure 1 shows a front-wheel drive vehicle loaded and secured to a transport carriage according to the invention; Figure 2 shows a side view of an unloaded transport carriage; Fig. 3 is a top view of an unladen carriage; Fig. 4 shows a section along the line C-C in Fig. 3 and the carriage lifting device; Fig. 5 is a section along the line A-A in Fig. 1 and shows the transport carriage lifted and coupled to a vehicle loaded thereon; Fig. 6 shows a section along the line D-D in Fig. 5 and how the second bogie of the vehicle is fitted to the frame of the transport wagon during transport; 4 63699 Fig. 7 shows a section along the line B-B in Fig. 1 and a coupling device between the transport carriage and the vehicle (second side shown).

A structure of a transport carriage according to the invention is described in detail below.

The frame 6, which consists of two parallel frame beams 7 connected to each other by transverse beams 5, is provided in the vicinity of its rear part with four traction wheels 4 arranged in pairs on coaxial shafts 27, two wheels outside the frame 6 and two frame beams 7 between.

The frame 6 is provided at its front end with a rope pulley 22. Behind this is arranged a hydraulic cylinder 17. The steel rope 19 is attached at one end to the piston rod 18 of the hydraulic cylinder 17 and arranged to pass under the rope pulley 22. The rope 19 is provided at its free end with a hook 21. The frame 6 is also provided at its front end with two upwardly directed fastening lugs 24 with through vertical notches 28. The fastening lugs 24 have notionally directed downwardly directed hooks 26 at their notches 28, the tips of which extend somewhat above the notches over.

The hydraulic cylinder 17 can be connected to the hose 14 by means of a quick connector 15 for connecting it to the hydraulic system of the vehicle 1 to be transported.

The frame beams 7 are provided along their inner edges with guide rails 9 and at their rear ends with stop projections 10.

The transport trolley is used as follows:

It is required that the transport carriage is in its loadable position (Fig. 2), whereby its front end rests on the ground and two brake shoes 11 are placed behind both of its outer wheels 4.

A front-wheel drive vehicle 1 with a bogie and tracks 2 on both bogie pairs 3 of the bogie is retracted onto the frame beams 7 of the transport wagon so that four sliders 12 placed under its bogie boxes 8 have to slide on the frame beams, preferably at least first. with toothpaste, in which case they are guided laterally by the guide rails 9. In this case, the brake pads 11 and the friction of the front end against the ground prevent the transport carriage from moving backwards. When the sliders 12 extend into the stop projections 10, the reverse movement stops and the front wheels 13 of the vehicle 1 are locked in the parking position. Track 2 has now been lifted off the ground.

The driver leaves the vehicle 1 and connects the hydraulic hose 14 provided with the quick coupler 15 to the valve housing 16 connected to the hydraulic system of the vehicle 1. The steel rope 19 is attached to the loop 20 in the vehicle 1 by means of a hook 21. The driver opens a drive valve fitted to the valve housing 16, whereby the pressurized hydraulic oil from the hydraulic pump of the vehicle 1 presses the piston rod 18 into the cylinder 17. The traction force then acts on the steel rope 19 which The transport carriage is fixed to the vehicle 1 by pushing two loose shafts 23 through the fastening lugs 24, each in its own tube 25, which tubes are welded to the base of the vehicle 1. The pressure in the piston is released by setting the operating valve to the return position.

The lower part of the transport carriage is then lowered to a position where the fastening lugs 24 rest on the shafts 23.

The axles are automatically secured so that the hooks 26 engage the ends of the inserted axles 23 when lowering the carriage.

The vehicle combination is then ready to be moved and the track chains 2 on the rear drive wheels 3 of the vehicle are located at a safe distance from the road surface above it. The rear drive wheels 3 are switched off during transport.

Once the combination has arrived at the intended location, the vehicle 1 is disconnected from the transport carriage in the reverse order to that described in the example above.
