Abstract

The invention provides a rear subframe assembly and a vehicle, wherein the rear subframe assembly comprises a first side longitudinal beam; a second side longitudinal beam symmetrically arranged withthe first side longitudinal beam; a front cross member whose top sides are connected to the first side longitudinal member and the second side longitudinal member, respectively; a rear cross member disposed opposite to the front cross member and having both sides of a side thereof connected to the first side longitudinal member and the second side longitudinal member, respectively, and wherein thefirst side longitudinal member, the second side longitudinal member, the front cross member, and the rear cross member are aluminum alloy pieces. The first side longitudinal member, the second side longitudinal member, the front cross member, and the rear cross member are aluminum alloy pieces, and the weight of the aluminum alloy pieces is lighter, thereby realizing the lightweight of the vehicle. The first side longitudinal member, the second side longitudinal member, the front cross member and the rear cross member are all cast in one mold, which saves a lot of welding procedures, makes the hard points of each support on the corresponding beam more accurate, improves the manufacturing accuracy, and thus makes the factory consistency of the rear subframe assembly better.

Description

technical field [0001] The present invention relates to the technical field of rear sub-frame, in particular to a rear sub-frame assembly and a vehicle. Background technique [0002] The sub-frame is the skeleton of the front and rear axles, and is also an integral part of the front and rear axles. It has the functions of supporting the front and rear suspensions, the engine and the steering gear, and is connected with the body through four or six points, which can block vibration and noise and reduce noise. Small vibrations and noises go directly into the cabin. In addition, the subframe, as the installation support for all parts of the front and rear axles, also plays a key role in the modular subassembly of the vehicle assembly. [0003] The traditional rear sub-frame is a sheet metal stamping part, the material is usually SAPH440, it is heavy, and it is welded to each bracket installed on it. Due to too many welded components, there will inevitably be problems with low ...
