COLLISION PROTECTION DEVICE FOR INDUSTRIAL VEHICLES, ESPECIALLY INDUSTRIAL TRUCKS

摘要

A collision protector that is retained in a rest position by spring force and upon collision with an obstacle, is displaced against the spring force and thus cooperates with a de-energizing device. The collision protector is mounted on the vehicle chassis by two swing arms arranged symmetrically non-parallel or in angle relationship to the longitudinal axis of the vehicle. This is to permit the deenergizing device to function effectively, irrespective of the place of impact of the obstacle against the collision protector and irrespective of any deformation of the collision protector. Each sliding link member is acted upon by the spring force and is displaceably positioned on a cross-shaft mounted on the vehicle chassis perpendicular to the longitudinal axis of the vehicle. Each sliding link member cooperates with the de-energizing device by means of a switching cam or ramp surface when displaced against the spring force. Two flexible retaining elements in the form of cables or bands connect the collision protector with the vehicle chassis and these are arranged adjacent the sides of the vehicle and symmetrically with respect to the longitudinal axis of the vehicle.
