The main supporting structure of an automobile onto which other components are attached is known as a vehicle frame. Almost all motor vehicles manufactured before 1930s have this skeleton which is separate from their bodies. In the course of time things changed as manufacturers shifted to unibody construction. This means that the bodywork and the chassis are integrated into one another.
On the contrary, hot rods still have frames separated from their bodies. Therefore, it is among the things that contribute to their uniqueness. Having separate frames gives space for installation of large engines. Greater linear speed is in turn allowed for by larger engines. Apart from the body, the hot rod frames also give support to other mechanical components. The strong frames in hotrods give them the ability to handle the static and dynamic loads without any unwarranted deflection or distortion.
There are multiple static and dynamic loads that hotrod frames handle such as the cargo weight. Others include the vertical and torsional twisting motions that result from the car going over uneven surfaces. Since most hotrods are meant for speed, they should contain a chassis that is able to endure the crosswise lateral forces from road conditions.
Transversal lateral forces can also be caused from the steering motion of the motor vehicle and side wind. The frame must be designed such that it can withstand sudden impacts from collisions. Torque from the engine transmission and longitudinal tensile forces from acceleration, compression of brakes, and starting must also be considered when constructing a frame for a hotrod.
Hotrod frames are mostly constructed using ladder type frame. Up to now, it is the simplest and oldest of all types of frames. Typical ladder frame has two channels, that is, trails or beams that have symmetry. The two are joined by transverse cross-members and run the whole length of the car. The cross-members are installed after specific intervals as considered fit. Similar to all other frame designs, it has its merits and demerits.
First advantage is the capability to provide proper beam resistance. The rails cutting across rails from front to the rear are the cause of this merit. On the contrary, if the quality of the cross-members is poor or simple it offers poor resistance to torsion or warping. One other factor one has to face during the ladder construction is to manage the total height of the automobile.
Generally, once a vehicle has ladder type frame its height tends to increase. This is brought about by the fact that a floor pan has to be added to the frame. In fact, the floor pan sits over the frame as opposed to sitting inside. Fortunately, since frames for hotrods are custom built this problem can be addressed easier before the work begins.
In conclusion, for safety purposes, one should have the chassis made by professionals. Experienced chassis producers are usually the best for the job. This is because they are in a better position to have the specification one needs achieved. Innovation and experience makes this possible. One should make sure the uniqueness of the hot rod is included in the chassis since hot rods are meant to be unique.
