    • The present invention relates to a collision detection device for detecting a collision of a vehicle, in particular, a rail vehicle, with a collision partner, comprising a collision unit (110), a mounting device (109) for mounting the collision detection device to the vehicle, and a sensor device (111). The collision unit (110) comprises at least one collision element (110.1) for contacting the collision partner in a collision event. The sensor device (111) is configured to generate a first collision signal representative of a first threshold collision event having a definable first threshold severity as a function of a first threshold relative deflection of the collision unit (110) relative to the mounting device (109) from a neutral position during the first threshold collision event. The collision unit (110) is coupled to the mounting device (109) via a resetting unit (114) and via a guide element (109.2), in particular a hinge element, defining a motion of the collision element (110.1) during the collision event. The resetting unit (114) is configured to undergo, during the threshold collision event, a first elastic resetting unit deflection from a neutral resetting unit position. The resetting unit (114) is configured to undergo, during a second threshold collision event having a second threshold severity greater that the first threshold severity, a second elastic resetting unit deflection, the second elastic resetting unit deflection being larger than the first elastic resetting unit deflection. The resetting unit (114) is configured to elastically reset, in a resetting action, from the second elastic resetting unit deflection to substantially the neutral resetting unit position upon removal of the collision partner, thereby resetting the collision unit (110) to substantially the neutral position.
    • 本发明涉及一种用于检测车辆特别是铁路车辆与碰撞对方的碰撞的碰撞检测装置,包括:碰撞单元(110),用于将碰撞检测装置安装到 车辆和传感器装置(111)。 碰撞单元(110)包括用于在碰撞事件中接触碰撞对象的至少一个碰撞元件(110.1)。 传感器装置(111)被配置为产生代表第一阈值碰撞事件的第一冲突信号,其具有作为碰撞单元(110)相对于安装装置(109)的第一阈值相对偏转的函数的可定义的第一阈值严重度 )在第一阈值碰撞事件期间从中立位置。 碰撞单元(110)经由复位单元(114)并且经由导引元件(109.2),特别是在碰撞期间限定碰撞元件(110.1)的运动的铰链元件而联接到安装装置(109) 事件。 复位单元(114)被配置为在阈值碰撞事件期间经历从中立复位单元位置偏移的第一弹性复位单元。 复位单元(114)被配置为在具有大于第一阈值严重性的第二阈值严重性的第二阈值碰撞事件期间经历第二弹性复位单元偏转,第二弹性复位单元偏转大于第一弹性复位单元 偏转。 复位单元(114)构造成在复位动作中弹出地将第二弹性复位单元的偏转弹性复位到基本上为零的中立复位单元位置,从而将碰撞单元(110)复位到基本上是中立的 位置。
