configuration of the beam-body
Figure 9
configured to beam-type body structure and substantially the same monolithic body (FIG. 9). Mounting the monolithic body of the vehicle engine suspension system and other components, in order to withstand these stresses quality or associated components, extremely rugged monolithic body comprising front and rear beams. However, the former does not comprise the beam-body, the rear beam, because the beam-body of the vehicle to support the use of girders or stress component mass and suspension system of the engine. Thus, the configuration of beam-type body configured like a monolithic body, the only difference is removed before, the rear beam.

In the monolithic body, the front fender separator is an important structural component for mounting to the overall suspension type body. However, in the beam-body of the vehicle, the front fender spacer (FIG. 10) just an inner panel (front fender mounted thereon), with the lower spacer bolts or spot welding together.
and the girder is connected to the vehicle body

by a beam-type frame body and a bolt, a nut and a rubber bush is connected together (FIG. 11). Typically, the use of 8 to 12 sets of bolts, nuts and the rubber bushing connected (FIG. 12). Because the body mounted on top of the rubber bushing, the buffer can be achieved, you will feel more comfortable when driving.
12
The rubber bush is divided into two types (FIG. 13): one is the compression type, plays the role of the gasket; the other One is the shear, by the inner collar and the outer rings. When the front portion of the beam-body collision occurs, if subject to greater impact girder, the inertial body will move, which may cause the mounting bolt and the vehicle body mounting bolt damaged area.

The new concept of the beam-body
In an example Toyota, Toyota adhering to the design of high strength and high energy absorption concept vehicle, is committed to improvingPassive safety of the vehicle, so as to achieve the purpose of protecting passengers. For example, by increasing the body to enhance the strength of the reinforcing plate, and the front and rear chassis design crumple zone to absorb the collision energy. The new beam-body design also adopted this concept.
Changes to the girders 1.
14
The front portion of the beam by axial compression absorbing impact energy, while the girder portion of the impact energy is absorbed by the curved arched. A front girder portion striker defeat down region, to absorb the impact energy (FIG. 14) can be axially compressed by the accordion-like.
15
The central beam consisting of a chassis having a larger cross-sectional area (FIG. 15), and the use of high strength steel, in order to enhance stiffness and strength.
Further, the span girder has widened central portion (FIG. 16), in order to withstand the impact force from the side impact.
