Abstract
An embodiment component integration type rear lower includes a body frame having an end portion of a first side and an end portion of a second side and having a predetermined length, a front-rear connection member connecting a side sill at the end portion of the first side and connecting a rear side member at the end portion of the second side, a bush mounting member coupling a bush to the end portion of the first side, and a coupled torsion beam axle (CTBA) mounting member coupled to at least one of a CTBA, a chassis spring, or a shock absorber, the at least one of the CTBA, the chassis spring, or the shock absorber being engaged with the end portion of the second side.
Claims23
A component integration type rear lower comprising:
- a body frame having an end portion of a first side and an end portion of a second side, and having a predetermined length;
- a front-rear connection member connecting a side sill at the end portion of the first side and connecting a rear side member at the end portion of the second side;
- a bush mounting member coupling a bush to the end portion of the first side;
- and
- a coupled torsion beam axle (CTBA) mounting member coupled to at least one of a CTBA, a chassis spring, or a shock absorber, the at least one of the CTBA, the chassis spring, or the shock absorber being engaged with the end portion of the second side,
- wherein the front-rear connection member comprises a center connector on which the side sill is to be placed from a top on an upper surface open space portion extending from the end portion of the first side, and a rear connector extending from the end portion of the second side to an open space and in which the rear side member is to be fitted in an upper surface of the open space.
A vehicle body frame comprising:
- a side sill providing a frame of an intermediate section of a vehicle and expanding to a battery space in which a battery is mounted;
- a rear side member providing a frame of a rear section of the vehicle;
- and
- a rear lower including a body frame of a predetermined length with a height difference defining a rear lower ground clearance, wherein a connection section between the side sill and the rear side member is formed of a front-rear connection member, an engagement portion between the side sill and a bush is formed of a bush mounting member, and an engagement portion of a rear wheel suspension is formed of a coupled torsion beam axle (CTBA) mounting member,
- wherein the bush mounting member includes a bush mounting hole fixed by a bush shaft in a state in which the bush is fitted in, and wherein, in the connection section of the side sill, the bush mounting hole is formed by being drilled in a center connector extending from the body frame to an upper surface open space in which a partial portion of the side sill is placed from above.
