Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The front subframe is the skeleton of the axle and is an integral part of the axle. In the related art, the front sub-frame is mostly made of a steel frame structure with a large number of structural sheet metal parts attached. There are at least the following problems in this front subframe:

[0030] (1) The steel frame structure is made of steel plate material, and the parts are made by blanking, drawing, forming, trimming and other processes of the steel plate material, and finally the parts are welded; and, a large number of additional structural sheet metal parts A lot of reinforced welding components are needed, so that the welding process of the whole sub-frame is more, thus the cost is high and the process is complicate...

Abstract

The invention discloses a front auxiliary frame and an automobile. The front auxiliary frame comprises: two longitudinal beams arranged in parallel at intervals, two transverse beams arranged in parallel at intervals, a plurality of fixing frames for auto parts on the longitudinal beams, two a first curved arm, one end has a connecting part, and the connecting part has a first open slot and a second open slot, the first open slots of the two first curved arms are respectively clamped and fixed with the two longitudinal beams, and the two first The second opening slots of the curved arms are snapped and fixed respectively with the two ends of a beam, and the two second curved arms have a connecting part at one end, and the first open slots of the two second curved arms are snapped and fixed with the two longitudinal beams respectively. , the second open slots of the two second curved arms are snapped and fixed with the two ends of the other beam respectively. The invention can adjust the installation positions of the suspension on the sub-frame, the control arm bracket and the bent arm bracket without redesigning a new mold, thereby improving the expandability of the sub-frame and reducing the development cost.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a front auxiliary frame and an automobile. Background technique [0002] The subframe is the skeleton of the front and rear axles and is an integral part of the front and rear axles. The subframe is not a complete frame, but a bracket that supports the front and rear axles and suspensions. The axles and suspensions are connected to the body through the subframe. The subframe includes the front subframe and the rear subframe, both of which are important parts of the car chassis. As an important support structure that provides installation positions for components such as stabilizer bars, steering gears, engine mounts, and swing arms, the subframe is a key force-bearing component, and its force is complex. In order to ensure sufficient strength and rigidity. [0003] The current subframe usually adopts a steel frame structure with a large number of structural sheet metal part...
