Description

Novel auxiliary frame

Technical Field

The utility model belongs to the technical field of the frame, especially, novel sub vehicle frame.

Background

The subframe can be regarded as a framework of the front axle and the rear axle, and is a component of the front axle and the rear axle. The subframe is not a complete frame, but merely a bracket that supports the front and rear axles and the suspension, through which the axles and suspension are then connected to the "main frame", conventionally referred to as the "subframe". The sub-frame has the functions of isolating vibration and noise and reducing direct entering of the sub-frame into a carriage, so that the sub-frame is mostly arranged on luxury cars and off-road vehicles, and the sub-frame is also arranged on an engine of some vehicles. Conventional vehicle bodies without sub-frames have suspensions that are directly connected to the body steel panels. Thus, the suspension rocker mechanisms of both the front and rear axles are discrete components and not an assembly. After the subframe is produced, the front and rear suspensions may be assembled to the subframe to form an axle assembly, which is then mounted to the vehicle body.

Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1-2, a novel auxiliary frame comprises a frame body 1, wherein a front mounting point 2, a middle mounting point 3 and a rear mounting point 4 are symmetrically arranged on two sides of the frame body 1, and the middle mounting point 3 is positioned between the front mounting point 2 and the rear mounting point 4; the front mounting point 2, the middle mounting point 3 and the rear mounting point 4 are arranged along the width direction of the frame body 1, the rear mounting point 4 comprises a first rear mounting point 4-1 and a second rear mounting point 4-2, and the adjacent first rear mounting point 4-1 and the second rear mounting point 4-2 are obliquely arranged with the width direction of the frame body 1.

The support body 1 is of a hollow structure, the front mounting point 2 and the rear mounting point 4 are located on the corners of the support body 1, and the middle mounting point 3 is located in the middle of the support body 1.

Two first rear mounting points 4-1 which are symmetrically arranged are arranged along the width direction of the frame body 1, two second rear mounting points 4-2 which are symmetrically arranged in the same way are also arranged along the width direction of the frame body 1, and the adjacent first rear mounting points 4-1 and the second rear mounting points 4-2 are arranged in a staggered manner.

Support 5 that mounting point 3 during support 1 both sides were formed with and are used for supporting, and support 5 sets up along the width direction of support body 1, support 5 outwards extends along 1 side of support body, the support 5 of 1 both sides of support body is located same straight line, support 5 and 1 formula structure as an organic whole of support body, through the mode fixed connection of welding or hot melt or bolt between support 5 and the support body 1, under the effect of support 5, make the position of well mounting point 3 be located outside 1 of support body, when not influencing 1 installations of support body, the realization is to the location support at 1 middle part of support body.

Preceding mounting point 2 and back mounting point 4 set up respectively in the relative both ends of support body 1, preceding mounting point 2 is located support body 1 with the tip both sides, after the same reason mounting point 4 also is located support body 1 with the tip both sides, first back mounting point 4-1 is close to the side setting of support body 1, mounting point 4-2 is close to the tip setting of support body 1 behind the second, the dislocation is behind first back mounting point 4-1 and the second mounting point 4-2 make support body 1 when whole car collision, the deflection of support body 1 is littleer.
