Car body: 1 – structural elements of the capsule; 2 – elements of the engine compartment; 3 – elements of the luggage compartment

Patent for utility model

Sergey Repin, professor at the Department of Land Transport and Technological Machines, Stanislav Grushetsky, associate professor at the Department, and Andrey Zazykin, dean of the Faculty of Automobile and Road Building, developed the body of a passenger car. Patent for utility model No. 219306 was received.

The structural elements of the capsule (1) are made of especially strong steel, which prevents its deformation when the car hits an obstacle. Elements of the engine (2) and luggage (3) compartments are made of soft steel to soften the dynamic load on the capsule by absorbing the energy of the car hitting an obstacle through deformation during a front or rear impact.

When a car hits an obstacle frontally, the frame elements of the engine compartment are deformed and the impact energy is partially absorbed. The motor, breaking away fr om the attachment points to the frame rails, moves down them and towards the capsule, rests against the inclined front shield and goes under the capsule, without causing harm to the driver and front seat passenger.

In the case of a high vehicle speed, the kinetic energy of the capsule moving forward is not completely extinguished due to the deformation of the engine compartment frame elements. The capsule is separated from the engine compartment at the points wh ere the resistance welding between the pillars breaks. Squeezing the capsule upward is facilitated by the inclined arrangement of the frame rails, resting on the lower part of the front shield. The capsule moves freely forward and upward, extinguishing the remaining kinetic energy.

When a car hits an obstacle fr om the rear or a moving object hits the car, the elements of the luggage compartment frame are deformed and the impact energy is partially absorbed. In the case of a high impact speed, the inertia of the capsule is not completely extinguished due to the deformation of the elements of the luggage compartment frame and the capsule is separated from the luggage compartment at the places wh ere the resistance welding between the pillars and arches of the rear wings, as well as the beams, breaks. The capsule moves freely back and up, extinguishing the remaining kinetic energy.

The Department of LTTM has been conducting research in the field of vehicle safety for more than twenty years. Many technical solutions developed here are protected by patents for inventions and utility models. These include devices that increase the passive safety of a car - bumpers, external airbags and others. Safe infrastructure devices have been developed - road shockproof systems, protective fences for poles. There are patents for devices that increase the safety of public transport stops.

Another direction of research is new devices to improve the safety of transport and technological machines intended for construction and road work, road maintenance, etc.
