Abstract

FIELD: vehicles.

SUBSTANCE: invention relates to automobile industry. The automobile consists of a rigid chassis structure and an interior body. Two internal rectangular load-bearing grilles configured to touch each other and connected by means of spot welding are installed on the automobile. The grilles are made of manganese-carbon steel 80 to 100 mm in height and 10 to 15 mm in thickness. One of the grilles is located in the engine area and is rigidly connected to the chassis, and the other grille is movably located in the interior area and is supported by skids on two sides of the body. The skids are mounted on the chassis in form of plates with ball bearings or wheels. In the event of automobile collision the first grille is deformed, as a result whereof the movable grille moves along the skids with the car interior and keeps the interior undamaged.

EFFECT: increased safety of passenger transportation is achieved.

Description

A known method of increasing the reliability of using a car when transporting passengers on the road, which consists in the use of thin steel sheets in the manufacture of its body / 1 /.

The disadvantage of this method is that in a collision of cars, the impact force can reach hundreds and thousands of megapascals, and this most often leads to the destruction of the front of the car and the displacement of the engine.

There is a known method of increasing the reliability of a car by using a curb (stop) in front / 2 /.

The disadvantage of this method is that with huge colliding masses (the amount of movement of cars), generating forces of hundreds and thousands of megapascals, this does not exclude the crushing of the front parts of the cars and injuries to the driver and passengers.

The aim of the present invention is to improve the safety of vehicle operation when transporting people and valuable goods on the road, leading to their death and injury.

This goal is achieved by the fact that in the known method of operating a car, consisting of a rigid structure of the chassis and the body of the passenger compartment, and allowing their destruction and unfortunate consequences in a collision of cars, a method is proposed to increase the operation of the car on the roads, characterized in that the device of the car consists of two internal rectangular bearing grids touching each other and fastened when driving on the road, for example, by spot welding, and made, for example, 80-100 mm high and 10-15 mm thick from durable manganese-carbon steel, one of which includes the engine area and is rigidly connected with the chassis, the other movable, including the passenger compartment with the driver and passengers, rests on both sides of the body on skids mounted on the chassis in the form of plates with ball bearings or small wheels along which the movable grille moves together with the passenger compartment in a collision of cars from the action of the first deforming grille saves salon with pass not damaged by soot.

In the drawings, FIG. 1-5 show diagrams of the design of the device of a car with a fixed and movable lattice.

FIG. 5. - Diagram of separation and displacement of the movable lattice in a collision with another vehicle:

7, 8 - respectively the seat of the passenger and the driver of the movable part of the body, 9, 10 - respectively, the movable lattice and its deformation in a collision of vehicles, 11 - the front part of the body, 12 - the part of the body connected with the movable lattice, 13 - the last three seats in the car ...

Execution example

In the pilot shop at the plant, a pilot model of the proposed vehicle device is made. To do this, on the base model of any type of car on its chassis, at the place of body attachment above the engine, a grid 1.2 is mounted in the form of a quadrangle 100-150 mm high and 80-100 mm thick from durable manganese-carbon steel and welded to the chassis. Then, on the section of the body of the cabin, on its two sides, plates 3 with a width of 30-50 mm are mounted on the chassis with rotating ball bearings 4 or small wheels soldered into them, creating a kind of runners. At the location of the body with the driver, a movable grate 2 with a height of 100-150 mm and a width of 30-40 mm is placed, also made of strong manganese-carbon steel, touching the first stationary and resting on skids with ball bearings 3, 4. The gratings are connected, for example, by spot welding, sufficient for road traffic. At the last stage, the car body is mounted and in the section of the passenger compartment with the driver and passengers 7, 8, 13 it is connected by welding to the movable grille 2. When colliding with an oncoming car, the fixed grille 1 perceives the main blow and, when deformed, it 9, 10 pushes the movable grille 2 and it rolls with the passenger compartment along the runners (plates with ball bearings 5), without causing injury to passengers and the driver.

The proposed car device is easy to manufacture and will help save hundreds and thousands of human lives. And giving a protruding convex shape, close to a triangular, in the front of the car, will save up to 5-10% of the fuel burned and increase its speed due to a decrease in air resistance to movement of the car.

According to press reports, 3,000 people die every day in road accidents around the world and about 100,000 are injured.

Claims (1)

A car consisting of a rigid chassis structure and an interior body, characterized in that the car has two internal rectangular bearing grilles with the possibility of touching each other and connected by means of spot welding, these grilles are made of manganese-carbon steel with a height of 80-100 mm and a thickness 10-15 mm, where one of the grilles is located in the engine area and is rigidly connected to the chassis, and the other grille is movably located in the area of the passenger compartment and rests on both sides of the body on runners mounted on the chassis in the form of plates with ball bearings or wheels, in a collision cars, the first grille is deformed, as a result of which the movable grille, together with the passenger compartment, moves along the runners and keeps the passenger compartment undamaged.
