Abstract
The invention relates to protective device for an articulated vehicle (1) comprising at least a first and second vehicle portion (4, 6); a control gear (8) connected to the respective vehicle portion (4, 6); and an actuating member (16) for, via the control gear (8), changing the relative position of the vehicle portions (4, 6) in relation to one another. The protective device (2) comprises at least one stiffening means (22), which fixes the position of each respective vehicle portion (4, 6) in relation to one another whenever the acceleration and/or speed of at least one of the vehicle portions (4, 6) exceeds a predetermined limit value. The invention also relates to a method for controlling a stiffening means of such a protective device (2) for an articulated vehicle (1).
Claims16
A protective device for an articulated vehicle comprising:
- at least front and rear vehicle portions;
- a control gear connected to the respective vehicle portions configured to allow a non-horizontal movement of the vehicle portions relative to each other;
- an actuating member for, via the control gear, changing the relative position of the vehicle portions in relation to one another;
- and
- at least one stiffening member, which fixes the position of each respective vehicle portion into a rigid position in relation to one another so that weights of both the front and rear vehicle portions are utilized so as to prohibit the non-horizontal movement of the vehicle portions and so that the control gear absorbs torque without any relative displacement of components belonging to the control gear, whenever the acceleration and/or speed of at least one of the vehicle portions exceeds a predetermined limit value, which happens when the vehicle is subjected to detonation of a mine.
