Device for the closing of bodies of vehicles such as trucks and the like, by a rigid cover with lengthwise arrangement of two or three elements, actuated via two linear actuators in series, with interpositioning of a transverse stabiliser element, integrating a device to eliminate the degree of freedom

摘要

With reference to figures 1-4-5-6, the present invention, applicable to the bodies of vehicles such as trucks and the like, concerns a cover 4, 4/1 of the type with two or three rigid and mutually hinged elements (segments, pitches) having a lengthwise kinematic evolution relative to the automobile, actuated by two linear actuators 30, 34 arranged in series, together interacting between cover and pivoting hatchback 5 by interpositioning between the pins 29, 28 of the ends of the rods 31, 35 of the actuators 30, 34, of plates 25 pivoting on the rear cover element 11, 11/1 with pin 27 and on the hatchback with pin 26, said plates 25 being integrated with a tubular element 22 for transverse stabilisation, the degree of freedom of the articulated structure being eliminated by the retention of the pin 39, 61, integrated to the element 11, 11/1, by means of hooks 50, 60 pivoting by pin 52, 59 on the element 10, 10/1, directly in the case of a two-element cover, indirectly via tubular rod 40 in the case of three-element cover, said rod 40 in turn being coupled to the rod 45, pivoting on the element 10 by means of the pin 44, and acting as a telescopic element limiting the angle a between the cover segments 10, 11.
