Problems solved by technology

[0005] However, the aforementioned vehicle body front structure is disadvantageous in that the suspension member cannot absorb any impact after the left and right rear portions of the suspension member are separated from the vehicle body frame.
Therefore, this structure has the problem of not being able to effectively absorb shocks.

Abstract

A vehicle body front part structure.A suspension member is fixed to a front part of a vehicle body from below. A stabilizer is fixedly held on an upper surface of the suspension member. The stabilizerhas bent portions. At the time of a front end collision of the vehicle, a rear part of the suspension member separates from the vehicle body for rearward movement of the suspension member relative tothe vehicle body to allow the bent portions to come into engagement with the vehicle body.

Description

technical field [0001] The present invention relates to a vehicle body front structure, and more particularly, to a vehicle body front structure provided in a configuration in which a rear portion of a suspension member is separated from a vehicle body frame during a vehicle collision. Background technique [0002] Conventionally, there is known a vehicle body front structure including a trapezoidal suspension member positioned under a front portion of a vehicle body frame. The suspension member is fixed to the vehicle body frame by means of bolts at four locations, that is, at a left front location, a right front location, a left rear location, and a right rear location. [0003] According to the known vehicle body front structure described above, at the time of vehicle collision (front-end collision), the front portion of the vehicle body frame is broken to absorb the impact of the collision, and the suspension member moves rearward. As such, if the suspension member is m...
