Abstract
Vehicle body frame includes a main frame section that is made of light metal and extends in a band shape from a front end portion to a rear end portion of the vehicle body frame to thereby form a compression wall portion, and a sub-frame section that is made of steel and fixedly mounted along the band-shaped main frame section. The sub-frame section forms a hollow structure in conjunction with the main frame section and forms a tension wall portion. The main frame section has a greater thickness than the sub-frame section.
Claims1
A vehicle body frame formed as a hollow structure of a generally rectangular sectional shape and including a compression wall portion and tension wall portion where compressive stress and tensile stress are produced, respectively, when an axial impact acts on said vehicle body frame, said vehicle body frame comprising:
- a main frame section made of light alloy and extending from a front end portion to a rear end portion of said vehicle body frame to thereby form said compression wall portion;
- and
- a sub-frame section made of steel and fixedly mounted along said main frame section to thereby form said hollow structure in conjunction with said main frame section and form said tension wall portion,
- said main frame section having a thickness dimension greater than a thickness dimension of said sub-frame section.
