Leveling system for motor vehicles

A leveling system for motor vehicles comprising:

• a frame;
• wheels connected to the frame;
• a dump body for carrying material pivotally connected to the frame about a first axis placed at the rear end of the vehicle;
• means for moving the dump body in relation to the frame, enabling the dump body to rotate around the first axis whereby material inside the dump body is unloaded;
• means for detecting inclination of the first axis to the horizontal;
• means for adjusting inclination of the dump body to the horizontal, said inclination adjusting means including:
• at least one bracket positioned between the frame and the dump body, the bracket being pivoted on a substantially horizontal pin perpendicular to the first axis, the pin defining a second axis and joining the frame to the dump body;
• at least two variable extension elements placed on opposite sides of the second axis, the variable extension elements connecting the bracket to the frame and adjusting inclination of the dump body relative to the frame according to inclination detected by the detecting means;
• the leveling system further comprising:
• sensor means positioned on parts of the motor vehicle and detecting the working position of the vehicle, the sensor means comprising at least one sensor positioned on a control for a parking brake;
• and,
• means for activating the inclination adjusting means according to the working position of the vehicle detected by the sensor means.

• at least two variable extension elements placed opposite each other on either side of the second axis, the variable extension elements connecting the bracket to the frame and adjusting the inclination of the dump body relative to the frame according to the inclination detected by the detecting means;
• the leveling system further comprising:
• means for stopping rotation of the bracket about the second axis in order to stop corresponding rotation of the dump body about the frame, said stopping means including at least one actuator with at least one end adapted for insertion in a corresponding seat of the bracket or of a rigid part connected to the bracket itself;
• sensor means positioned on the end of the actuator and detecting rotation of the bracket;
• activation means for activating the adjustment means according to bracket rotation detected by the sensor means so that the adjustment means can be activated when the bracket is not stopped.

A leveling system for motor vehicles comprising:

• a frame connected to wheels of the motor vehicle;
• a dump body for carrying material, the dump body being pivotally connected to the frame about a first axis placed at the rear end of the vehicle and about a second axis positioned longitudinally along the motor vehicle;
• means for moving the dump body in relation to the frame, enabling the dump body to rotate selectively around the first or the second axis, whereby the material inside the dump body is unloaded;
• means for detecting inclination of the first axis to the horizontal;
• means for adjusting inclination of the dump body to the horizontal including:
• at least one bracket positioned between the frame and the dump body, the bracket being pivoted on a substantially horizontal pin perpendicular to the first axis, the pin defining a third axis and joining the frame to the dump body;
• at least two variable extension elements placed opposite each other on either side of the third axis, the variable extension elements connecting the bracket to the frame and adjusting inclination of the dump body to the frame according to the inclination detected by the detecting means;

• the leveling system further comprising:
• sensor means for detecting the rotation of the dump body about the second, longitudinal axis and sending a corresponding signal;
• and,
• means for activating the dump body inclination means according to the signal sent by the sensor means as to rotation of the dump body about the longitudinal axis so that the adjusting means are disabled when the dump body is rotated about the longitudinal axis.
