Abstract

In a vehicle front structure (10), a cross member (52) which is disposed above paired side members (12) includes vehicle width-direction both end portions extending toward a rear side of the vehicle. The cross member (52) is connected with vehicle front-side portions of the paired suspension towers (42) at edges of the extending portions. Therefore, when a vehicle has a frontal collision at high speed, a collision load applied to the cross member (52) can be effectively received by the paired suspension towers (42), and can be transmitted to the paired suspensions. Thus, the cross member (52) can effectively receive the collision load, and can efficiently transmit the collision load to the rear side of the vehicle.

Claims (10)

1. A vehicle front structure comprising:

paired side members which are disposed at a right side portion and a left side portion in a front portion of a vehicle;

paired suspension towers which are disposed at a right side portion and a left side portion in the front portion of the vehicle, and which support paired suspensions on a vehicle front side; and a cross member which is disposed above the paired side members, which includes extending portions that are disposed at right and left sides in a vehicle lateral direction so as to extend toward a rear side of the vehicle, and which is connected with vehicle front-side portions of the paired suspension towers at edges of the extending portions.
2. The vehicle front structure according to claim 1, wherein the vehicle front structure includes a bumper reinforce which is connected with vehicle front-side ends of the paired side members, and which is disposed on a vehicle front side of the cross member; and the cross member is connected with the paired side members.
3. The vehicle front structure according to claim 1 or 2, wherein paired crash boxes are disposed at vehicle front-side end portions of the paired side members; each of the paired crash boxes has low compressive strength in an axial direction as compared to a portion of each side member other than the crash box; and vehicle rear-side ends of the paired crash boxes are disposed at positions matching positions of vehicle front-side ends of connection portions between the cross member and the paired side members and a position of a vehicle front-side end of the cross member in a vehicle longitudinal direction, or the vehicle rear-side end of the paired crash boxes are disposed on a vehicle front side of the vehicle front-side ends of the connection portions between the cross member and the paired side members and the vehicle front-side end of the cross member.
4. The vehicle front structure according to any one of claims 1 to 3, further comprising a load transmission member which connects a power unit in the front portion of the vehicle with the cross member in the vehicle longitudinal direction so that a load can be transmitted between the cross member and the power unit.
5. The vehicle front structure according to any one of claims 1 to 4, wherein the power unit in the front portion of the vehicle is disposed on a vehicle rear side of the cross member.
6. The vehicle front structure according to any one of claims 1 to 5, further comprising:
an output shaft which is provided in an engine in the power unit in the front portion of the vehicle, which is disposed along the vehicle lateral direction, and which outputs driving force of the engine; and a differential which is provided in the power unit, which is disposed on a vehicle front side of the output shaft, and which transmits the driving force from the output shaft to a front wheel of the vehicle.
7. The vehicle front structure according to any one of claims 1 to 6, further comprising a sub frame which has a rectangular frame shape in a plan view, and on which the power unit in the front portion of the vehicle is mounted.
8. The vehicle front structure according to any one of claims 2 to 7, wherein a distance between connection portions between the cross member and the paired side members is shorter than a distance between connection portions between the cross member and the paired suspension towers.
9. The vehicle front structure according to any one of claims 1 to 8, wherein the cross member has a tube shape.
10. The vehicle front structure according to claim 9 further comprising:

intake air ports which are formed in the cross member, and which are opened to insides of the suspension towers; and an air cleaning mechanism which is disposed between the power unit in the front portion of the vehicle and the cross member in the vehicle longitudinal direction, which is connected with the cross member, and which cleans air that is taken in from the intake air ports through the cross member.
