Self-propelled construction machine

摘要

A self-propelling construction machine has a machine frame, an operating drum and a drum housing enclosing the operating drum. The drum housing is closed off by a front and/or rear sealing element and/or lateral sealing element. The construction machine has a mechanism for raising and lowering the at least one sealing element. A measuring unit is configured so that the measuring unit measures the forces acting on the sealing element when the sealing element encounters an obstacle. A control unit generates a control signal for raising the sealing element when the force measured by the measuring unit is larger than a predetermined limit value, so that the sealing element is raised.

主权项

1. A self-propelled construction machine, comprising:
a machine frame; an operating drum supported from the frame; a drum housing surrounding the operating drum, the drum housing including at least one sealing element for closing the drum housing off to a ground surface; an actuator configured to raise and lower the at least one sealing element relative to the operating drum, the actuator being configured so that the at least one sealing element contacts the ground surface with a predetermined contact force when the sealing element is not raised; a sensor configured to detect a force acting on the at least one sealing element when the at least one sealing element encounters an obstacle; and a control unit, operatively connected to the sensor and the actuator and configured to generate a first control signal such that the actuator raises the at least one sealing element relative to the operating drum when the force detected by the sensor is greater than a predetermined limit value.
