The invention relates to a vehicular multifunctional cab rear suspension support, which comprises a top plate, a back plate, a first side plate, a second side plate, frame connecting holes, cab suspension
cushion mounting holes, a cab suspension
cushion mounting through hole, a safety hook frame, an arc-shaped rib plate, engine ECU (
electronic control unit) fixing lifting lugs and an engine ECU fixing boss, wherein the back plate is fixedly connected with the top plate, two sides of each of the first side plate and the second side plate are connected with the top plate and the back plate respectively, the frame connecting holes are arranged on the back plate, the cab suspension
cushion mounting holes, the cab suspension cushion mounting through hole and the safety hook frame are arranged on the top plate, two ends of the arc-shaped rib plate are fixedly connected with the top plate and the back plate respectively, the engine ECU fixing lifting lugs are horizontally arranged on the back plate, and the engine ECU fixing boss is perpendicularly arranged on the back plate and positioned below the engine ECU fixing lifting lugs. The vehicular multifunctional cab rear suspension support realizes arrangement of a large-sized combined mud guard and installation of an engine ECU, and integrates
peripheral parts of a traditional cab rear suspension support, so that the problem of decentralized arrangement is solved, the number of the parts is decreased, product cost is reduced, components are lightened, and a whole vehicle is more compact and attractive in arrangement.
