Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, therefore the utility model is not by the restriction of following public specific embodiment.
Fig. 2 is the block diagram of the utility model automobile control arm.Fig. 3 is the schematic diagram of pressing type bulb connection mode in the utility model automobile control arm.Fig. 4 is the block diagram of mounting hole in the utility model automobile control arm.Fig. 5 is the cutaway view of mounting hole in the utility model automobile control arm.
As shown in Figures 2 to 5, the utility model discloses a kind of automobile control arm 30, comprise Control arm upper slice 31, Control arm bottom sheet 32 and ball pin 33.Control arm upper slice 31, Control arm bottom sheet 32 and ball pin 33 all adopt metallic material to make.Wherein, Control arm upper slice 31 is provided with the first perforate 311, Control arm bottom sheet 32 is provided with the second perforate 321, Control arm upper slice 31 is connected relatively with Control arm bottom sheet 32, such as a whole by being welded into, thus make the first perforate 311 and the second perforate 321 form through mounting hole 35 in opposite directions.Ball pin 33 is inserted and secured in mounting hole 35.
Preferably, at least one side of Control arm upper slice 31 is provided with the first flange 312, at least one side of Control arm bottom sheet 32 is provided with the second flange 322, first flange 312 and the second flange 322 are oppositely arranged, thus make to form gap 36 between Control arm upper slice 31 and Control arm bottom sheet 32, gap 36 can guarantee that ball pin 33 is pressed into its normal function of rear maintenance.
First perforate 311 is provided with the 3rd flange 313, second perforate 321 and is provided with the 4th flange 323, the 3rd flange 313 and the 4th flange 323 is relatively arranged, and is located in gap 36.3rd flange 313 and the 4th flange 323 are all preferably cylindrical tube shape.3rd flange 313 and the 4th flange 323 are all formed by the technique shaping of flange after first punching.
In addition, between ball pin 33 and Control arm upper slice 31, ball pin dust boot 34 is installed.The shape of ball pin 33 is mated with the shape need of mounting hole 35, and ball pin 33 and mounting hole 35 are preferably interference fit.Coordinated with the magnitude of interference of internal diameter size by outside dimension, the body of ball pin 33 with Control arm 30 is fixed.With connecting panel be set in prior art compare with the connection mode of rivet, its weight is lighter, and cost is lower.
Herein, the preferred dimension limit in gap 36 is 0.5-1.0mm, the internal diameter 0.1mm (as shown in Figure 5) larger than the internal diameter of the second perforate 321 of the first perforate 311.This structure can prevent from touching the end face 314 of the first perforate 311 at the ball pin dust boot 34 in process that press-fits of ball pin 33 and causing damage effectively.
In sum, the bulb connection mode that the utility model automobile control arm adopts is compared to traditional riveted joint and bolt connecting mode, and its structure is more simple, and after eliminating pressing plate, weight is also lighter.Meanwhile, Control arm body adopts the form of flange, and unconventional welded sleeve, also embody the theory of light-weight design.Described automobile control arm adopts forced ball head structure to substitute original riveted joint/bolted mode, while meeting the matching requirements of Control arm own, decrease number of parts, meet light-weight design requirement, reduce cost, decrease the risk caused because bolt connects.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
