A reinforcement structure for rear wheel housing of vehicle wherein a wheel housing inner panel and wheel housing cover of rear wheel housing are respectively coupled by a plurality of reinforcement members to further reduce vibration levels at intermediate and high speed booming domains, such that noise generated by resonance with exciting frequency input from road surface while a vehicle is running can be greatly decreased, the rear wheel housing including a wheel housing cover and a wheel housing inner panel protruded upwards to install a shock absorber of rear suspension system and wheels at left/right tip end parts of rear floor panel, the structure comprising: first and second reinforcement members for being respectively coupled up and down at front corner part formed by front and side surfaces of the wheel housing inner panel and extended to define closed sections upto a rear floor panel; a third reinforcement member extended fieldwise and coupled to a bottom surface of the wheel housing cover between first and second mounting parts formed toward external side of the vehicle body; and a fourth reinforcement member crosswise extended and coupled to a central portion of the first and second mounting parts.
A vehicle frame includes a pair of spaced frame rails and at least one cross member connecting the frame rails. A tower structure is on one of the spaced frame rails for supporting a floor of a load-carrying bed spaced above the frame rails.
Coupling members include a first coupling portion (X) that couples rear quarter inner members to upper surfaces of rear suspension base members, a second coupling portion (Y) that couples upper surfaces of the rear suspension base members together, which are located on the right and the left in pairs, and a third coupling portion (Z) that joins the second coupling portion to couple the rear quarter inner members together, which are located on the right and the left in pairs, the coupling member being integrally formed, and there is formed a bulkhead structure in a portion surrounded by the first, second and third coupling portions.
A rear pillar structure of a vehicle frame is provided for supporting a dual mode tailgate including a pillar member having a first leg and a second leg. The first leg extends generally vertically along a side wall of the vehicle frame which partially defines a load carrying bed. The second leg extends along a cross member connecting a pair of frame rails of the vehicle frame. A support member is mounted inside the first leg for reinforcing the first leg at a location at which the dual mode tailgate connects to the pillar.
