Abstract
The utility model aims at providing a rear auxiliary car frame. Under the premise that required stiffness and intensity are not reduced, assembling steps and cost can be reduced. To achieve the rear auxiliary car frame, the rear auxiliary car frame consists of an upper piece and a lower piece. The rear auxiliary car frame is characterized in that the upper piece is a deep drawing piece and forms a rear auxiliary car frame body, and the lower piece is a plate-shaped patch and welded on the upper piece. The upper piece is provided with two positioning holes one on side of the length direction, the positioning holes are both formed by the upper piece in a punching mode and positioning holes and formed by the upper piece and the lower piece in a welding mode, an upper control arm connecting portion and a lower control arm connecting portion are arranged on the upper piece, and the upper control arm connecting portion is provided with two installing holes which are suitable for assembling of different car types.
Description
Technical field
The utility model relates to automobile rear sub-frame.
Background technology
Rear secondary frame for vehicle is very important safety and load member in the passenger-car chassis, as the bearing substrate at car section rear portion, bears and transmit the various force and moments that produce in the vehicle traveling process.Therefore, the rigidity of Rear secondary frame for vehicle, intensity, fatigue life etc. vital effect is played in intensity, road-holding property and the safety of vehicle integral body.On the other hand, under the prerequisite that does not reduce required Rigidity and strength, reducing manufacturing technology steps and manufacturing cost, is the target that industry is pursued always.
The utility model content
The purpose of this utility model is to provide a kind of Rear secondary frame for vehicle, and it can reduce installation step and cost under the prerequisite that does not reduce required Rigidity and strength.
For realizing the Rear secondary frame for vehicle of described purpose, comprise slice and lower, be characterized in, upper slice for the deep-draw part, consist of the Rear secondary frame for vehicle body, lower for flat sticking patch and be welded in slice, upper slice have two knock holees in a side of length direction, this knock hole be the knock hole of upper slice drawing also be upper slice and the knock hole of lower welding forming, be provided with upper suspension arm connecting portion and Lower control arm connecting portion on upper slice, the upper suspension arm connecting portion has two mounting holes of the assembling that is applicable to two kinds of different automobile types.
The Rear secondary frame for vehicle of a brand new according to Rear secondary frame for vehicle of the present utility model, it only by the welding of upper and lower two parts, has namely reached required Rigidity and strength, has greatly reduced welding step and manufacturing cost, for further batch manufacturing, lay the foundation.Upper slice be a deep-draw part, lower only is a very little tabular or similar flat sticking patch, its Sheet Metal Forming Technology is simple, welding process is easy, easy for installation, is a high-intensity Rear secondary frame for vehicle.Because the knock hole on upper slice is the knock hole of punching, also be the knock hole of welding assembly, guaranteed the unification of positioning datum, so, upper and lower is location-independent, is conducive to the welding debugging.At the upper mounting hole that two upper suspension arms are arranged, it can be applicable to the assembling of two kinds of different automobile types simultaneously, has saved so to a great extent manufacturing cost.Mainly install Control arm and Lower control arm on the Rear secondary frame for vehicle, its toe-in, camber angle are mainly controlled by the mounting hole of back axle, and need not to regulate again, have saved human resources.Rational in infrastructure, easy to assembly, be a typical four-bar linkage.
Description of drawings
Fig. 1 is the schematic perspective view of automobile rear sub-frame.
Fig. 2 is the schematic perspective view of the automobile rear sub-frame of partly cut-away.
The specific embodiment
As depicted in figs. 1 and 2, among the embodiment of the present utility model, automobile rear sub-frame by upper slice 1 and lower 2 be welded, upper slice 1 be that the deep draw steel plate is through the deep-draw casting die of drawing, it has consisted of the body of automobile rear sub-frame, lower 2 sticking patch for tabular (contain approximate dull and stereotyped shape) its role is to strengthen upper slice intensity of 1, and seals slice 1.Two ends in a side of upper 1 length direction are formed with respectively knock hole 11, knock hole 11 be the knock hole of upper slice drawing also be upper slice and the knock hole of lower welding forming, guaranteed the unification of positioning datum.Upper slice 1 also be respectively arranged with everywhere upper suspension arm connecting portion 3 and Lower control arm connecting portion 4, upper suspension arm connecting portion 3 has two mounting holes 31,32, can be respectively applied to connect the assembling of the upper suspension arm of two kinds of different automobile types, Lower control arm connecting portion 4 has a mounting hole 41.
Subframe is flexible coupling by four points of connection 5 and car load vehicle body, adopts arc welding process between upper and lower 1,2, and fusion length is short, and welding deformation is little, invests littlely, lightweight, and welding process is simple.At upper 1 upper suspension arm connecting portion 3 mounting hole 31,32 of two upper suspension arms is arranged, it can be applicable to the assembling of two kinds of different automobile types simultaneously, has saved so to a great extent manufacturing cost.Mainly install Control arm and Lower control arm on the Rear secondary frame for vehicle, its toe-in, camber angle are mainly controlled by the mounting hole of back axle, and need not to regulate again, have saved human resources.Rational in infrastructure, easy to assembly, be a typical four-bar linkage.This subframe compact overall structure, rigidity is high, and intensity is good.This Rear secondary frame for vehicle integral rigidity is high, and intensity is good, and is lightweight, can satisfy the requirement of design fully.
