(RU, patent for invention №2181677, CL B61G 11/16, F16F 7/12, publ. 2002)

The drawbacks are:

- guides and traction-rails ties with edges connecting the three plates are made sequentially as a whole and in the collision the front ends of the guides are for the dimensions of the device, so the device cannot be used in case of direct contact of flat surfaces of cars, which narrows its technical capabilities;

- running belts and edges as one unit with rigid rods and traction-guide couplers complicates the design of the device and does not provide for the creation of a given value of the force effects on the entire length of the move, especially at the beginning and at the end, which reduces the efficiency of the device.

The technical result of the invention is the expansion of technical capabilities, simplifying the design and improving the efficiency of the device.

This technical result is achieved in that the module for energy dissipation in collisions of vehicles, consisting of at least three p is it: mobile, interim and fixed, between which there is an energy-absorbing elements, and the fixed plate is connected with the vehicle, movable and intermediate plate mounted for movement and serial sectioning of the material with energy-absorbing elements, the first located between the movable and intermediate plates, and then between the intermediate and stationary plates, the maximum cutting force of the first is less than the minimum effort of the second cutting; cutting the surface of the energy-absorbing elements in the form of rings with outer multiple-spiral and longitudinal grooves, the number of which must be at least two energy-absorbing cells fixed with one hand through bushings with cutting edges, the clamping bushings, washers with fasteners at the intermediate and stationary plates and connected with the other side, respectively, with the movable plate and the intermediate plate with the possibility of cutting the installed thickness of the material of the outer surface of the multiple spiral rings the number of rings, the material and the volume of the cutting layer are determined by the required power consumption module, and an increase in the maximum effort of the stationary cutting plate is provided with installation of additional energy-absorbing elements.
