Abstract
The utility model aims to provide a back dragging arm with a punching and welding composite structure, which has no need of specially developing a casting or forging blank. In the back dragging arm, an inner sheet and an outer sheet are punching pieces; the inner sheet and the outer sheet are two parts which are separately formed along the length direction of the back dragging arm; by viewing from a cross section, the inner sheet is a semi-closed part with three side faces, and the outer sheet is a part with a side face; the inner sheet and the outer sheet are welded to from the main body of the back dragging arm with the punching and welding composite structure; a reinforcing board extends along the length direction of a drawing arm, and is located between the inner sheet and the outer sheet; one side edge of the reinforcing board is welded on the inner sheet, and the other side edge of the reinforcing board is welded on the outer sheet; a front sleeve is welded at the front end of the main body of the drawing arm; an upper sleeve is welded at the upper side of the back end of the main body of the drawing arm; an inner sheet and outer sheet connecting bracket is provided with a shaft part; the shaft part passes through holes at the back ends of the inner sheet and the outer sheet, and is welded into a whole body together with the inner sheet and the outer sheet; and the inner sheet and outer sheet connecting bracket is mounted in the shaft of a supporting wheel, so as to form a wheel mounting point.
Description
Technical field
The utility model relates to the Rear drag arm of rear overhang rack.
Background technology
Mostly car is separately to manufacture and design, assemble up then with wheel stand in many connecting rods rear suspension (rear knuckle) and Rear drag arm (back trailing arm) at present, and the rear wheel support overwhelming majority is Casting Parts or Forging Parts.The problem that such structure exists is: wheel stand needs exploitation blank redevelopment separately and processing tool technology, time-to-market is long, reject rate is high, thereby causes integrated cost high.
The utility model content
The purpose of the utility model is to provide a kind of punching press welding composite structure Rear drag arm, and it is through the blanked part welding fabrication, needn't develop casting or forging blank specially, only needs to adopt common punching press welding technique can accomplish development task.
For realizing the punching press welding composite structure Rear drag arm of said purpose; Be characterized in; Comprise that interior sheet, outer plate, brace panel, front sleeve, upper bush, interior outer plate connect support and abs sensor support, interior sheet and outer plate are blanked part, and interior sheet and outer plate are two parts that separate shaping along the length direction of Rear drag arm; From cross-sectional plane; Interior sheet is the part with semi-closed shape of three sides, and outer plate is the part with a side, and interior sheet and outer plate welding constitute the body of punching press welding composite structure Rear drag arm; The length direction along the towing arm of brace panel extends, and between interior sheet and outer plate, on the sheet, the opposite side side weld was connected on the outer plate in a side was welded on; Front sleeve is welded on the front end of the body of towing arm, is used to connect vehicle body, and upper bush is welded on the rear end upside of the body of towing arm, is used to connect the back top link of rear overhang rack; Interior outer plate connects support and has axial region; Sheet and outer plate were in the hole of rear end in this axial region penetrated into; And integrally welded with interior sheet and outer plate, interior outer plate connects pack into the axle of support wheel of support, thus formation wheel attachment point; Interior outer plate connection support, brace panel, abs sensor support also are blanked part, and the abs sensor support is welded on the rear end of outer plate.
Reliability all obtained bigger raising with accuracy of manufacture after punching press welding composite structure Rear drag arm was designed to one-piece construction with rear wheel support and Rear drag arm in the aforementioned techniques scheme, needn't be size relatively large casting or forging blank spare development and Design clamping tool for machine work specially and purchased batch with mechanical cutting processing special plane.Only need to adopt common punching press welding technique can accomplish development task, this has shortened time-to-market, has overcome the high defective of reject rate, has practiced thrift cost.
Description of drawings
Fig. 1 is the decomposition view of punching press welding composite structure Rear drag arm.
Fig. 2 is that the axle of punching press welding composite structure Rear drag arm is surveyed view.
Fig. 3 is the section-drawing along A-A line among Fig. 2.
The specific embodiment
As depicted in figs. 1 and 2, sheet 1, outer plate 2, brace panel 3, front sleeve 4, upper bush 5, interior outer plate connected support 6 and ABS (vehicle skidproof brake system) sensor stand 7 in punching press welding composite structure Rear drag arm comprised.
As shown in Figure 2, the global shape and the existing Rear drag arm of punching press welding composite structure Rear drag arm do not have big difference, but are appreciated that from embodiment shown in Figure 1 it is configured with substantial variation.Rear drag arm forms through reasonable curved course design back according to the requirement of car load suspension kinematical dynam.
To shown in Figure 3, interior sheet 1 welds the body that the back constitutes punching press welding composite structure Rear drag arms with outer plate 2 like Fig. 1, and interior sheet 1 is a blanked part with outer plate 2; Through drawing; Interior sheet 1 is two parts that separate shaping along the length direction of Rear drag arm with outer plate 2, and from cross-sectional plane, interior sheet 1 is the part with semi-closed shape of three sides; And outer plate 2 is for having the part of a side, interior sheet 1 with become a barrel-contoured part after outer plate 2 welds.On the sheet 1, the opposite side side weld was connected on the outer plate 2 in one side of brace panel 3 was welded on, and brace panel 3 also extends along the length direction of towing arm.Front sleeve 4 is welded on the front end of the body of towing arm, is used to connect vehicle body, and upper bush 5 is welded on the rear end upside of the body of towing arm, is used to connect the back top link of rear overhang rack.Interior outer plate connects support 6 and has axial region, and axial region penetrates in the hole of interior sheet 1 and outer plate 2, and welds with interior sheet 1 and outer plate 2, and interior outer plate connects the axle of the support wheel of can packing in the support 6, thus formation wheel attachment point.Interior outer plate connection support 6, brace panel 3, abs sensor support 7 also are blanked part.Abs sensor support 7 is welded on the outer plate 2.
Position after aforementioned forward and backward, inside and outside isotropy term all is installed on the vehicle body with Rear drag arm is reference.
