Manufacture Of Hot Rod Frames

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.

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.

In most cases, hot rods are constructed with the ladder type frame. Up to now, this is the design that is the simplest and the oldest. In a typical ladder type frame, there are two symmetrical channels on the frame namely trails or beams. Similar to others, they traverse the whole length of the car and they are linked by traverse cross-members. The placement of cross-members is done at intervals deemed fit. This kind of frame comes with its own advantages and disadvantages like any other.

Its ability to offer good beam resistance is one of its advantages. This advantage is realized due to the continuous rails running from the rear to front. On the other hand, its resistance to warping or torsion is quite poor especially if the cross-members used are simple or of poor quality. The other thing that a person constructing a ladder frame has to deal with is the overall height of the vehicle.

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.
