Front body structure of vehicle

Abstract

Provided is a front vehicle body structure of a vehicle (1) capable of improving vehicle body rigidity with respect to a load acting on a suspension housing (12) and a load acting on a sub-frame (14)even if the suspension housing is disposed at a position separated to the front of the vehicle with respect to an engine bulkhead (4). The front body structure of the vehicle (1) has the pair of leftand right suspension housings (12) provided in desired positions separated from the dash panel (4) toward the vehicle front side. The front body structure of the vehicle (1) further includes a first ring-shaped structural frame (W1) that passes through shroud members (11) and is substantially ring-shaped in front view, a second ring-shaped structural frame (W2) that passes through the suspension housings (12) and is substantially ring-shaped in front view, and a third ring-shaped structural frame (W3) that passes through hinge pillars (2) and is substantially ring-shaped in front view, in which these ring-shaped structural frames are joined to each other by apron reinforcements (8), front side frames (10), and side members (141) of the sub-frame (14).

Description

technical field [0001] The present invention relates to, for example, a front vehicle body structure of a vehicle in which a ring-shaped vehicle body frame forming a substantially ring shape in a vehicle width direction in a frontal view is formed in the front vehicle body. Background technique [0002] In vehicles such as automobiles, for example, the front suspension shock absorber is connected to the skeleton part of the vehicle body through the suspension shell. ride comfort. [0003] In general, relatively large loads tend to act on the suspension shell via the front suspension dampers, so if the front body is deflected due to the load applied via the front suspension shock absorbers, it may cause handling problems. performance, and passenger comfort. [0004] Here, for example, in Patent Document 1, a pair of left and right shock absorber housing reinforcement members, an engine bulkhead panel reinforcement member, and a front subframe constitute a ring-shaped vehicl...

AI Technical Summary

Problems solved by technology

[0007] However, when the suspension housing is separated toward the front of the vehicle with respect to the engine bulkhead, it is difficult to use the cowl as a closed cross-sectional member connecting the left and right suspension housings. The rigidity of the car body framework of the load on the frame shell and the load acting on the subframe
