发明名称 CHASSIS DE VEHICULE AUTOMOBILE A COQUE AUTOPORTEUSE MONOLITHIQUE ET ELEMENT DE RENFORT
摘要 <p>The frame part comprises a set of monolithic self-supporting shells (10, 11, 12, 14b, 15b), and reinforcing elements (V1-V3) connected to the shells. The reinforcing elements extend over an entire length of a central frame portion in a longitudinal direction of the frame to ensure recovery of a tensile or compression parallel to the longitudinal direction, recovery of forces and bending moments about a transverse direction of a chassis and/or around a vertical direction, and recovery of torques about the longitudinal direction. The frame part comprises a set of monolithic self-supporting shells (10, 11, 12, 14b, 15b), and reinforcing elements (V1-V3) connected to the shells. The reinforcing elements extend over an entire length of a central frame portion in a longitudinal direction of the frame to ensure recovery of a tensile or compression parallel to the longitudinal direction, recovery of forces and bending moments about a transverse direction of a chassis and/or around a vertical direction, and recovery of torques about the longitudinal direction. The two reinforcement elements are placed on both sides of the frame part following the transverse direction of the frame. The shells are connected with each other by bonding so as to define hollow bodies of tubular form between the shells and over the entire length of the frame part following the longitudinal direction, where each hollow body is delimited to form the reinforcing element. One of longitudinal ends of the hollow bodies includes elements for recovery of the tensile or compression parallel to the longitudinal direction, recovery of forces and bending moments about the transverse direction of the chassis and/or around the vertical direction, and recovery of torques about the longitudinal direction. The elements of recovery of forces and bending moments include a housing delimited by the hollow bodies and intended to receive an insertion member (18) by pertaining to another frame part such as front portion or rear portion of the frame. The hollow bodies include a support intended to support overall vertical efforts transmitted by a structural element such as window post. Each hollow body is delimited by main monolithic self-supporting shells and by monolithic self-supporting shells of reinforcement in form of a profiled open section extending over the entire length of the frame part following the longitudinal direction and fixed by bonding against a wall of the main shells. A section forming the monolithic shells of reinforcement presents a general shape of omega. The monolithic shells of reinforcement are formed by molding of a composite material. An independent claim is included for a frame of a car.</p>
