Abstract
Official abstract text for this publication.
The invention relates to a strut rod made of composite material for a suspension of a front axle of a vehicle, including: an upper part coupled to a rod and piston assembly connected to a vehicle body; and a U-shaped lower part including two brackets for fixing a knuckle arm of the vehicle. This strut rod includes means for detecting a crack. This detection means includes at least one additional edge positioned so as to project from an outer surface of the U-shaped lower part of the strut rod in a region where a crack possibly occurs in the case of an accidental shock on a wheel of the vehicle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A strut rod made of composite material for a suspension of a front axle of a vehicle, the strut rod comprising: an upper part coupled to a rod-piston assembly fixed to a body of the vehicle, and a U-shaped lower part including two brackets for fixing a knuckle arm of the vehicle, wherein the strut rod includes a detection means for detecting a crack, the detection means including at least one additional edge positioned so as to project from an outer surface of the U-shaped lower part of the strut rod, in a region where the crack possibly occurs in a case of an accidental shock on a wheel of the vehicle. 2. The strut rod according to claim 1 , wherein the at least one additional edge is directed to a direction substantially perpendicular to a preferential direction of the crack under an impact of the accidental shock. 3. The strut rod according to claim 1 , wherein the at least one additional edge is positioned so as to project from a front surface of an end portion of one bracket of the two brackets forming a U-shape for fixing the knuckle arm, the additional edge being configured to be cracked in the case of the accidental shock on the wheel of the vehicle of to indicate a need for replacing the strut rod. 4. The strut rod according to claim 1 , wherein front surfaces of end portions of the respective brackets of the U-shaped lower part are curved and formed of two adjacent circular-arc sections that are connected by intermediate circular sections, and the at least one additional edge is positioned on a lower one of the circular-arc sections. 5. The strut rod according to claim 1 , wherein the at least one additional edge is fabricated as a monoblock with the brackets of the U-shaped lower part on which the edge is positioned. 6. The strut rod according to claim 5 , wherein the additional edge is fabricated by molding at a same time as the strut rod during a molding operation of the strut rod. 7. A vehicle, comprising: a front axle having a suspension apparatus of a type of the strut rod made of composite material, wherein the strut rod made of composite material is the strut rod described in claim 1 .
