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 several dynamic and static loads that the frame of a hotrod deals with such as the cargo weight. Others include the torsional and vertical twisting motion resulting from the motor vehicle going over surfaces that are uneven. As most hotrods are designed for speed, they must have a chassis that can withstand the transverse lateral forces resulting from the conditions of the road.
Steering motion of vehicles and side wind can also cause transversal lateral forces. The frame should be designed in that it can endure unexpected impacts resulting from collisions. Forces from longitudinal tensile forces and the engine transmission from starting, compression of brakes, and acceleration should also be put in mind during construction of hotrod frame.
The ladder type frame is most commonly constructed for hot rods. So far, it is the oldest and simplest of all designs. Typical ladder frame has two channels, beams or trails that are symmetrical. They two run the entire length of the car and are connected by transverse cross-members. The cross-members are placed after a certain interval as deemed fit. Like any other design of frame it has its shortcomings and advantages.
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.
