Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] like figure 2 and image 3 As shown, an automobile rear subframe provided by the embodiment of the present invention includes a main body plate 1 and a connecting plate 2. The main body plate 1 is bone-shaped with large ends and a small middle, so that the rear subframe takes up space. It is greatly reduced, the weight is greatly reduced, and a considerable space is avoided in the middle position, which provides great convenience for the arrangement and installation of other systems, such as fuel tanks and exhaust systems. The cross section of the main board 1 is The first groove-shaped structure with the opening facing downwards, the connecting plate 2 is locate...

Abstract

The invention relates to the field of cars, and discloses a rear auxiliary frame of a car. The rear auxiliary frame comprises a main body plate and a connection plate, wherein the main body plate is in a bone shape big in two ends and small in the middle, the cross section of the main body plate is of a first grooved structure with an opening facing downwards, the connection plate is disposed below the middle part of the main body plate, and the middle parts of the main body plate and the connection plate are in butt joint with each other to form a cavity structure; and a plurality of bushing installation holes are separately formed in two ends of the main body plate. The main body plate is in a bone shape big in two ends and small in the middle, so that the overall layout is compact, the occupied space is greatly reduced, and the weight is greatly reduced; a large space is reserved in the middle position, so that great convenience is provided for the arrangement of other systems such as an oil tank and an exhaust system; the cross section of the main body plate is of the first grooved structure with the opening facing downwards, the connection plate is disposed below the middle part of the main body plate, and the middle parts of the main body plate and the connection plate are in butt joint with each other to form the cavity structure, so that the overall rigidness, the strength and the twisting and bending modality of the rear auxiliary frame can be improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile rear auxiliary frame. Background technique [0002] As an important part of the car chassis, the rear sub-frame is mainly used to provide installation support for the rear suspension system, and at the same time block the vibration and noise transmitted from the tires to the suspension system, reduce its direct entry into the cabin, and improve the overall performance of the vehicle. ride comfort. Secondly, the rear sub-frame is a component that ensures the assembly relationship between the rear suspension system and the vehicle body. The rear suspension system and the rear sub-frame are first assembled on the sub-assembly line to form the rear axle assembly, and then the assembly is combined with Body combined assembly, this assembly structure is easy to install, has high versatility, reduces assembly and research and development costs, but the most important thing is t...
