There are numerous versions of vehicles on the roads and railways. By way of example, mention is made of the publications F1 962062, F1 964313, DE 4310065, DE 3203426, SE 380210, GB 1320431, GB 2231007 and GB 2303592.

The aforementioned patents mainly focus on getting the vehicle on and off the rails.

In the known inventions, the vehicle is often moved on rails by lifting and / or using 15 different ramps and guides. The present invention does not require separate expensive additional structures for entering and exiting the rails. Known Iron ··. road maintenance vehicles require equipment and materials used in work. **. separate means of transport (particularly rails); either a rail car or; train. The service vehicle of this invention carries with it all the necessary:: · ·: 20. The car also has a crane, so it's a completely independent unit: ':': for rail maintenance and repairs.

This invention enables the above advantages to be achieved and the drawbacks to be eliminated by a service run, which is essentially characterized by what is stated in the claims.

The body of the service drive is a standard four-wheel drive truck. • · ·: X on the front and rear of the front wheels and behind the rear wheels are hydraulically lowered »» #, ···. and lifting axles to which the rail wheels are attached. The rear axle 30 is mounted at its center through a joint to the car body so that it can rotate at different angles, both vertically and horizontally, close to the car axles 2 112189 so that the rear track wheels can be pressed against the rails. The center wheel rail mounted on the ball joint allows the car to be tilted up to the set limit on the wheel axles and thus also with the track.

The front wheels driving away from the rails drive the front end of the vehicle 5 onto the rails and press its rails against the rails. When the car is on rails, the beam attached to the hydraulic cylinder of the rear rail unit prevents the car from tilting sideways relative to the rail wheel axles. Going to the track does not require a crosswalk, but you can enter it at any point that is flat enough for the truck. Movement on the rails is effected by the driving wheels 10 of the car. Dual wheels can be replaced with wider standard single wheels for better traction.

Repair and maintenance work very often requires long material such as poles and rails that require a special means of transport. On the body of the service car, hydraulic cylinders are mounted on the front and rear of the platform to lift and lower the material transport rack, which is built on them and on the stabilizer arms, so that it is on the side of the car near loading and unloading position. · · ·. longitudinal axis.

The rear rail wheel assembly 2b consists of a hydraulic cylinder 112189 3 attached to the car body, at the lower end of which a transverse beam 4 is attached which limits the lateral inclination of the rail wheel axles 5 over a set limit. The beam 4 is secured to the beam 6 connecting the axes 5 via a ball joint 7. The shafts 5 and the beams connecting them have a circular circumference 8 on which the ends of the beam 4 are held in place and prevented from tilting beyond what is permitted.

The periphery 8 is shaped such that when the wheel axles are perpendicular to the rails, i.e. the service car is in the running position, the tilting is prevented. The ends of the beam 4 are secured to the car body by folding stabilizer arms 9 which support the beam and prevent its rotation.
