Abstract

The invention relates to a road making machine with a running gear and at least one material deflector which is arranged in front of the running gear in the driving direction and which can be pivoted up and lowered. The road making machine includes a control system by means of which an operator can choose at least between a laying operating mode and a transport operating mode. The control system is adapted to automatically completely pivot the material deflector up in the transport operating mode, and to let the operator adjust the pivot position of the material deflector manually in the laying operating mode.

Claims

1. Road making machine with a running gear and at least one material deflector located in front of the running gear in the driving direction and which can be pivoted up and lowered, and comprising a control system by means of which an operator can choose at least between a laying operating mode and a transport operating mode and wherein the control system is adapted to automatically completely pivot the material deflector into the up position in the transport operating mode, and to let the operator adjust a pivot position of the material deflector manually in the laying operating mode.

2. Road making machine according to claim 1, wherein the material deflector can be pivoted up with respect to the horizontal about an angle (α

) between about 30°

-35°

.

3. Road making machine according to claim 1 wherein the material deflector can be pivoted by means of a hydraulic system.

4. Road making machine according to claim 1, wherein the material deflector is retained with free travel permitting it to swivel to the top and/or to the bottom when it is not completely pivoted into the up position.

5. Road making machine according to claim 4, wherein a point of application of a hydraulic cylinder at the material deflector is retained in an oblong hole.

6. Road making machine according to claim 4, wherein a hydraulic cylinder takes a floating position to retain the material deflector with free travel.

7. Road making machine according to claim 1, wherein the material deflector is retained, when completely pivoted into the up position.

8. Road making machine according to claim 7 wherein a special operational control is provided that automatically causes the material deflector to pivot up into its completely raised position on actuation during the laying operating mode.

9. Road making machine according to claim 1, wherein the road making machine is a road finishing machine, an excavator or a feeder.

10. Method of operating a road making machine having a running gear and a material deflector located in front of the running gear in the driving direction and which can be pivoted up and lowered, which comprises:

Using a control system to select between between a laying mode and a transport operating mode of the road making machine, Automatically pivoting, the material deflector up to its highest pivot position when the road making machine is in the operating mode transport, and that the operator manually adjusts a pivot position of the material deflector in the laying operating mode.

11. Method according to claim 10, wherein the material deflector is retained with free travel permitting it to pivot up and/or down, when it is not completely pivoted in the up position.

12. A road making machine comprising:

running gear,

at least one deflector positioned in front of the running gear and being adjustable to move between an up position and a down position,

a control system having a first laying operating mode and a second transport operating mode and including apparatus for automatically moving the material deflector into the up position when the control system is in the transport operating mode.

13. The road making machine of claim 12 wherein the control system includes apparatus for manually adjusting the position of the material deflector when the control system is in the laying operating mode.

14. The road making machine of claim 13 wherein the material deflector can be pivoted up at an angle of up to 30°

with respect to the horizontal.

15. The road making machine of claim 13 wherein the material deflector can be pivoted up at an angle of 35°

with respect to the horizontal.
