The safety cage is the main structural element of a racing car, designed to ensure the passive safety of the athlete. For each car model, an individual frame is built, welded from a set of structures and pipes and installed in certain places in the car body. Normally installed roll cage is not designed to be dismantled.
Necessary
Frame materials - metal or aluminum pipes. Welding machine. Locksmith tools and a set of keys
Instructions
Step 1
The frames have a variety of designs of various levels of complexity, non-separable and removable. Removable frames are attached to the sill and floor. Non-dismountable (built-in) frames are of high complexity and are combined with the load-bearing elements of the body. These models are ordered for custom tuning only. Please note that when the frame is installed on a 4-door or 5-door car, it becomes a 2-door 2-seater. The rear seats are engaged in the plexus of the frame tubes. The main material of the frames is 45x2.5 and 20x2 cm aluminum tubes. The requirements for racing cars force the frame to be painted in bright colors. Decide on the type of frame to be installed and the car on which it will be installed.
Step 2
First, make a model of the body from plasticine. This will help harmonize the bodywork. It is better to make a model in full size, and then develop a model of the frame according to your drawings. After that, keeping the dimensions, a life-size frame is built for a real car. If the body mockup is made of wood or plywood, you can immediately make a ready-made frame for it. Use thick-walled metal pipes or aluminum as the material. Make complex curved parts composite, from several parts. Weld metal pipes, flatten aluminum and fasten with bolts and rivets. You can fasten the aluminum pipes together by slipping them over a steel bar and then bolting them together. To have more options for constructing the frame, do not use circular pipes. Combining materials brings good results.
Step 3
When creating a frame, decide how many doors the car should have and how they should open. It may be convenient if the doors open upwards.
Step 4
The frame consists of spacers, kerchiefs, rods. The front strut increases the rigidity of the front of the body and reduces deformation of the body cups when cornering. Gussets reinforce the places of the wheel arches, suspension struts and stiffeners. The booms are movable mounts that connect the power unit and the strut and reduce possible engine displacement during sharp turns, starts and brakes. The lower strut reduces movement of the front suspension bracket arm and improves handling, stability and body life, but is labor intensive during installation. The rear strut increases the rigidity of the rear of the body and reduces the movement of the rear suspension cups. The rear strut must always be attached to the rear bodywork.
Step 5
In addition to the spacers, the stiffness is increased by reinforced welds, reinforced stabilizers and cross-sections. Due to the lack of professional welding equipment for most motorists, to strengthen the welding seams, you should consult a specialist. Subframes and cross members need to be reinforced or replaced with more durable models.
