Abstract

Usage: in the automotive industry, in particular on sports cars participating in competitions. SUMMARY OF THE INVENTION: the carcass contains longitudinal stiffeners (1) of stiffness that are located along the passenger compartment of the car, an arched element (2) located across the passenger compartment behind the driver and navigator seats and attached to the base of the vehicle via bolt connections (4). The longitudinal struts (5) are rigidly connected to the longitudinal elements (1) and the arcuate element (2). Between each other elements

Description

Figure 1
The invention can be used in the automotive industry, in particular in sports cars participating in competitions.
A known safety cage construction is comprised of a safety arch, two half arcs, two struts installed diagonally along the passenger compartment, and one cross strut made detachable. Such a carcass construction protects the middle and rear parts of the passenger compartment (German patent No. 2103611, class B 60 R 2/02, 1980).
Closest to the invention in technical essence is a roll cage of a passenger compartment of a passenger car, comprising an arcuate element transversely located in the middle of the passenger compartment, longitudinal stiffeners rigidly connected at the rear by an arcuate element, a transverse strut connecting the front parts of the longitudinal stiffeners , the vertical sections of which are fixed with their lower ends on the bottom of the car in front of the passenger compartment. The frame also contains longitudinal struts that are connected to the vertical sections of the arcuate element and the longitudinal elements of the stiffness. rear longitudinal stiffeners, obliquely mounted and connected at one end to an arcuate element and the other to a car body, a diagonal spacer attached at one end to the arcuate element and the other end to the bottom of the rear longitudinal stiffener.
However, this frame is not reliable enough and does not ensure the safety of car passengers.
The purpose of the invention is to increase the reliability and safety of car passengers by increasing the strength of the joints of the carcass elements.
This goal is achieved in that in the safety cage of the passenger compartment of a passenger car, mainly a sports one, consisting of an arcuate element mounted in the middle of the passenger compartment transversely to the longitudinal axis of the vehicle and fixed to the body of the latter, longitudinal stiffeners, including upper horizontal sections rigidly connected to the back with an arcuate element, and in front of each other with a transverse strut, and vertical sections secured by the lower ends in front of the fat on the bottom of the car, longitudinal struts installed on the sides of the passenger compartment and connected to vertical sections of longitudinal stiffeners and an arcuate element, rear longitudinal stiffeners mounted obliquely and connected at one end to the upper part of the arcuate element, and the other to the car body, diagonal spacers attached at one end to the horizontal part of the arcuate
0 element on one of the sides of the cabin, and the other end to the bottom of the rear longitudinal stiffener, located on the opposite side of the cabin, is equipped with rear supports
5 longitudinal stiffeners, each of which is fixed between the lower parts of the arcuate element and the corresponding rear longitudinal stiffener, and the longitudinal stiffeners are made in the form of single arcs with inclined sections located between the upper ends of the vertical sections of the longitudinal elements and the front parts of their upper horizontal sections. Figure 1-3 shows the proposed
5 safety cages in three projections.
The roll cage of the passenger compartment of a passenger car, mainly a passenger car, contains longitudinal stiffeners 1, which are installed on the sides
0 interior of the front and middle parts of the car and include upper horizontal sections, rigidly connected at the rear with an arcuate element 2, and in front of each other with a transverse strut 3,
5 and vertical sections secured with lower ends in the front part of the passenger compartment on the underbody of the vehicle using bolt connections 4. The arcuate element 2 is installed transversely in the middle of the passenger compartment
0 longitudinal axis of the car and is fixed on the basis of the body of the latter using bolted joints 4. Longitudinal stiffeners 1 are made in the form of single arcs with inclined sections,
5 located between the upper ends of the vertical sections of the longitudinal elements, the bend of which makes an angle within 130 °, and the front parts of their upper horizontal sections, the bend of which is equal to an angle of 150 °. The longitudinal struts 5 are located on the sides of the passenger compartment and are rigidly connected to the vertical sections of the longitudinal stiffeners 1 and the arcuate element 2, with
5, they are installed at an angle of 15 ° to the normal (horizontal) by one third of the height of the doorway of the cabin, and vertically have a bend to the center of the cabin within the angle of 173 °.
The rear longitudinal stiffeners 6 are mounted obliquely and connected at one end to the upper part of the arcuate element 2, and the other to the car body using bolted connections 4. The diagonal strut 7 is attached at one end to the horizontal part of the arcuate element 2 on one of the sides of the passenger compartment, and the other end - to the lower part of the rear longitudinal element of rigidity 6, located on the opposite side of the passenger compartment.
The safety cage is provided with supports 8 of the rear longitudinal stiffeners 6, each of which is fixed between the lower parts of the arcuate element 2 at an angle of 60 ° and the corresponding rear longitudinal stiffener at an angle of 45 °.
The transverse strut 3, the upper horizontal part of the arcuate element and the diagonal strut 7 are made detachable in the center of the passenger compartment and connected by bushings 9, which are installed with the possibility of their fixation using bolt connections 10.
The frame is made of seamless metal pipes and can be quickly removed from the car and assembled in the passenger compartment of the car. By disconnecting the three bushings 9 along the upper part of the carcass and the six attachment points to the underbody of the car through the tailgate, two parts of the carcass can be easily removed.
