DESCRIPTION:
BRIEF SUMMARY
For many years railroad companies have been trying to deliver to the address of the receiving party full car loads intended for users who do not have their own tracks.
Thus, they have succeeded in delivering cars of the so-called axle type, using especially lowered chassis.
A lowered chassis which makes possible the home delivery of truck cars was recently developed, but the sizes of such a device are such that it can only be used in exceptional cases.
There exists still another solution known as the "Kangaroo system" according to which there is moved by rail, on a car with lowered chassis, entire trucks or only semi-trailers. At departure and at arrival, the truck leaves the lowered car, generally under its own power, to go by road to the nearby location of the receiving party. Such a solution is very expensive, because the weight of the lowered car plus the weight of the truck, or semi-trailer, exceed the weight of the paying merchandise.
The object of the present invention is to provide a vehicle which makes possible mixed transportation, by road and by rail, of merchandise, without however ending with a vehicle which is too large or the empty weight of which is excessive relative to the transported merchandise.
The vehicle according to the present invention is characterized in that said vehicle comprises at least one axle of the rail type, meant to roll on railroad rails, said vehicle being further equipped, on the one hand with attachment means for at least one highway pneumatic wheel set and, on the other hand, with coupling means suitable to cooperate with a corresponding device of a semi-trailer truck tractor.
The attached drawing shows, schematically and by way of example, a preferred form of execution and a modification of a vehicle comprising the object of the present invention.
FIG. 1 is a side elevation of a vehicle according to the present invention.
FIG. 2 is a side elevation showing the vehicle when one of its ends is raised by a jack.
FIG. 3 is a side elevation of a portion of the vehicle converted into the trailer of a semi-trailer truck.
FIG. 4 is a top plan view, of a vehicle in the process of being transformed.
FIG. 5 shows in plan and on an enlarged scale, the coupling device of the two parts of the vehicle, in disengaged position.
FIG. 6 is a side view of FIG. 5.
FIG. 7 corresponds to FIG. 6 but shows the coupling device in the engaged position.
FIG. 8 is an enlarged detail of the coupling device.
FIG. 9 is a side view of a modification as in the case of a two axle car.
FIG. 10 is a bottom plan view of the car according to FIG. 9.
The vehicle shown in FIG. 1 is a car with bogies or trucks 1 pivotally mounted at the ends of a chassis 2 on pivots 3. Chassis 2 is formed of two half-chassis 4 and 5 the length of which is approximately the same, and which are joined by connecting means 6 which will be described in detail below.
The facing or first ends of the chassis parts 4 and 5 are provided with couplers 7 which can cooperate with a corresponding coupling means of a semi-trailer tractor, and with a second pivot 8 similar to pivots 3. The car is fitted with buffers 9 and it comprises at both of its ends, supporting surfaces 10 for the jacks.
The car described is provided for conversion into two semi-trailer truck trailers, and FIGS. 2 and 4 illustrate different stages of that conversion.
The first operation consists in substituting the two trucks 1 of the railroad car with two sets of highway pneumatic wheel sets 11.
The replacement of a truck or bogie is a common one, especially for replacement of a defective truck or for the substitution of a narrow-gauge truck for a wide-gauge truck as is done, for example, at the Franco-Spanish border.
The replacement of a truck is done, as shown in FIG. 2, by lifting one side of the car by means of jacks 12, so as to release pivot 3 from connection with bearing 13 of the truck 1, in which it is placed. Truck 1 is then replaced with a set of highway pneumatic wheel sets 11 and chassis 2 is let down to place pivot 3 into part 14 of highway pneumatic
