Description

Rear secondary frame for vehicle and automobile
Technical field
The utility model belongs to automobile accessory frame technical field, more particularly to a kind of Rear secondary frame for vehicle and automobile.
Background technology
Existing Rear secondary frame for vehicle is usually frame mouthful formula, and as shown in Figures 1 and 2, frame mouth structure is by front beam 1a, rear cross beam 2a, left longeron 3a and right vertical beam 4a are welded to form.Left front control arm mounting bracket 5a, left back control arm mounting bracket 6a are welded to On left longeron 3a;Control arm mounting bracket 8a is welded on right vertical beam 4a behind control arm mounting bracket 7a, the right side before right.Suspension is installed Support 9a is welded on front beam 1a;Rear stabilizer bar left installation bracket 10a is overlapped on left longeron 3a and on rear cross beam 2a and passed through Be welded and fixed, rear stabilizer bar right mounting bracket 11a be overlapped on right vertical beam 4a with rear cross beam 2a and by being welded and fixed.Left longeron 3a is welded with left reinforcing plate 12a with front beam 1a junctions, and right vertical beam 4a is welded with right reinforcing plate with front beam 1a junctions 13a.Front beam 1a two ends are welded with left front bushing installation set 14a and right front lining installation set 15a, rear cross beam 2a two ends weldering It is connected to installation set 17a behind left back installation set 16a and the right side.
As shown in Fig. 2 left longeron 3a is welded by left longeron upper plate 301a with left longeron lower plate 302a, right vertical beam 4a by Right vertical beam upper plate 401a is welded with right vertical beam lower plate 402a.Rear cross beam 2a is by rear cross beam upper plate 201a and rear cross beam lower plate 202a is welded.Left back control arm mounting bracket 6a installs branch by the left back 601a of control arm mounting bracket I and left back control arm The 602a of frame II is welded.Control arm mounting bracket 8a is pacified by the 801a of control arm mounting bracket I behind the right side with control arm behind the right side behind the right side The dress 802a of support II is welded.Suspension mounting bracket 9a is right by the left reinforcing plate 901a of suspension mounting bracket, suspension mounting bracket Reinforcing plate 902a is welded with suspension installing plate 903.
The Rear secondary frame for vehicle, front beam 1a is inner high voltage moulding pipe, left front bushing installation set 14a and right front lining installation set 15a is ironcasting.Rear cross beam 2a, left longeron 3a, right vertical beam 4a, left front control arm mounting bracket 5a, left back control arm install branch Control arm mounting bracket 8a, rear stabilizer bar left installation bracket 10, rear stabilizer bar behind frame 6a, right preceding control arm mounting bracket 7a, the right side Installation set 17a is metal plate punching behind right mounting bracket 11a, left reinforcing plate 12a, the left back installation set 16a of right reinforcing plate 13a and the right side Part.It can be seen that, constituting the parts material of the Rear secondary frame for vehicle includes metal plate punching part, pipe fitting and ironcasting, thus heavier-weight is (logical Often more than 20kg), it is difficult to meet new-energy automobile lightweight requirements.
In addition, parts broad categories independent in the Rear secondary frame for vehicle, and have similarity piece, easily obscure parts;Zero Part difference in size is big, the problem of smallclothes solder skip easily occur;Component structural is complicated, mold design and associated clamps design difficulty Greatly, precision is relatively difficult to ensure card in terms of parts shaping;In production process, production management difficulty is big, and cost is high.
Also, left longeron upper plate 301a constitutes left longeron 3a, right vertical beam upper plate with left above and below longeron lower plate 302a weldings 401a constitutes right vertical beam, rear cross beam upper plate and horizontal stroke after welding composition above and below rear cross beam lower plate with above and below right vertical beam lower plate 402a weldings Beam 4a.These parts, in welding up and down, the distance between upper and lower plate is integrally relatively difficult to ensure card;Because left longeron 3a and the right side are vertical Beam 4a is longer, and weld seam is long during upper and lower plate weld, due to welding temperature distortion, left longeron 3a and right vertical beam 4a two after the completion of welding The risk of tilting occurs in end.Due to being difficult to ensure that rear cross beam 2a upper and lower plate splices the thickness of welding, therefore, rear cross beam 2a Two ends presence the risk of installation set 17a behind left back installation set 16a and the right side can not be installed.
In addition, left longeron 3a glue right vertical beam 4a are connected with front beam 1a, rear cross beam 2a with Type of Welding, the left peace of rear stabilizer bar Dress support 10a is welded on rear cross beam 2a and on left longeron 102, rear stabilizer bar right mounting bracket 11a is welded on rear cross beam 2a and the right side On longeron 102, left longeron 3a, right vertical beam 4a are yielding during due to welding and two ends are tilted, therefore rear stabilizer bar left installation bracket There is overlap joint injustice in 10a, rear stabilizer bar right mounting bracket 11a, the risk of stabiliser bar can not be properly installed after welding.
In addition, the left back 601a of the control arm mounting bracket I and left back 602a of control arm mounting bracket II is welded to form left back control The 801a of the control arm mounting bracket I and 802a of control arm mounting bracket II behind the right side is welded to form behind the right side behind arm mounting bracket 6a processed, the right side Control arm mounting bracket 8a.Left front control arm mounting bracket 5a, left back control arm mounting bracket 6a are welded on left longeron 3a;It is right Control arm mounting bracket 8a is welded on right vertical beam 4a behind preceding control arm mounting bracket 7a, the right side.Welding material is heated, and influences zero Part installation site precision.In the prior art, whole Rear secondary frame for vehicle welding position is more, and parts are influenceed by welding temperature, reduction Subframe overall installation accuracy and intensity.
