Problems solved by technology
[0005] However, since the cab underframe has a raised portion, the following problem occurs: when a cab-type truck collides against a rigid wall (hereinafter referred to as an obstacle) (hereinafter such an accident is referred to as a frontal collision), and When a collision force (load) in front of the vehicle is thus applied to the front end of the front portion, stress tends to concentrate on the upper and lower ends of the raised portion, causing the cab chassis to bend and deform around the upper and lower ends

A floor underframe (5) for a vehicle disposed at the lower part of a cab has a front part (11) disposed at the front of the cab and extending in the longitudinal direction of the vehicle, a rising part (12) bent upward and extending from the rear end of the front part (11), a rear part (13) bent and extending from the top end of the rising part (12) toward the rear of the vehicle and disposed under a sitting seat (7), and an easily bendable part (14) which is formed in the rear part (13) and on which stress is concentrated when a compression load is inputted from at least either one of the front end of the front part (11) and the rear end of the rear part (13). The easily bent part (14) is disposed at a position below substantially the center, in the front-rear direction of the vehicle, of the sitting seat (7). The rear part (13) is upwardly bent at the easily bent part (14) when a compression load is inputted in the rear part (13) from at least either one of the front end of the front part (11) and the rear end of the rear part (13).
Description
technical field [0001] The invention relates to an undercarriage arranged under the driver's cab. Background technique [0002] In general, a truck in which the driver's seat position in the cab is arranged in front of the engine (hereinafter referred to as cab-over truck) has a pair of cab underframes (or underframes) arranged under the cab. The cab chassis includes a front portion arranged on a front side, a raised portion raised from a rear edge of the front portion, and a rear portion extended rearward from an upper end of the raised portion; wherein a passenger seat is arranged on the rear portion. [0003] Patent Document 1: JP-A 11-208516. Contents of the invention [0004] The problem to be solved by the present invention [0005] However, since the cab underframe has a raised portion, the following problem occurs: when a cab-type truck collides against a rigid wall (hereinafter referred to as an obstacle) (hereinafter such an accident is referred to as a frontal...
