Abstract

PURPOSE:To increase the absorbing quantity of collision energy at collision of a vehicle which is provided with front wheels in front of its engine. CONSTITUTION:In a vehicle which is provided with front wheels 48 in front of its engine 46, impulsive load is transmitted from the front wheel 48 to a suspension arm 14 at collision of the vehicle. The load is concentrated on the bead 20 formed in the vicinity of fitting part of the suspension arm 14 of a suspension member 12. As a result of this, the suspension member 12 is deformed, the suspension arm 14 is tilted rearward against the vehicle, the front wheel 48 is retreated so as to increase the plastically deformable part of a side member 10, and hence the absorbing quantity of collision energy is increased.

2. Description of the Related Art When a vehicle collides, a very large collision energy is applied to the body of the vehicle and a part of the body is deformed. In general, a vehicle is composed of a rigid body, so if the body is not devised to absorb collision energy, the impact on the occupants in the vehicle compartment at the time of collision may be large. Therefore, the body is provided with a structure that absorbs the collision energy, and is devised so that the passenger is not affected by the collision. For example, when a vehicle crashes into the front, the front side member is deformed from its front end portion by the load of the collision (hereinafter referred to as plastic deformation) to absorb the energy of the collision.

In FIG. 2, when a vehicle has a frontal collision, a front bumper (not shown) installed in front of the side member 10 is first deformed due to a collision load from the front of the vehicle, and then the side member 10 is deformed. The front end portion 10a is plastically deformed. Then, when the side member 10 is plastically deformed to the length K, the rigid front wheel 48 receives a collision load so as to be pushed rearward of the vehicle. Further, the suspension arm 14 supporting the front wheel 48 is also pushed rearward of the vehicle by the collision load, and the rubber bush 36,
The load concentrates on the front mounting portion 25 and the rear mounting portion 26 via 38. Then, the bead 20 starts to cause deformation in the rear mounting portion 26 of the suspension member 12.

As a result, as shown by the broken line in FIG. 3, the suspension member 12 is deformed in the vicinity of the bead 20, and the suspension arm 14 tilts rearward of the vehicle with the bush 36 as a fulcrum. Further, the front wheel 48 also moves backward in association with it. As a result of the above operation, since there is the rigid front wheel 48 at the time of collision, the portion of the length L (see FIG. 2) of the side member 10 that could not be plastically deformed can be plastically deformed by the retreat of the front wheel 48. Therefore, the plastically deformable portion of the side member 10 becomes long, and the amount of collision energy absorbed increases.
