Specific embodiment

The technical solution of the utility model is described in further detail below by specific embodiment and with reference to attached drawing.

As shown in figures 1 to 6, a kind of control arm welding assembly, including controlling arm body 100, the control arm body 100 is wrapped Include the first arm body 110 and the second arm body 120 that are separated from each other extension arranged on 100 one end of control arm body, 110 He of the first arm body Second arm body 120 and the edge of control arm body 100 are all provided with the flanging 130 of oriented same direction bending, the control arm master The other end of body 100, which is equipped with, turns to connecting pin, and the outboard end of the first arm body 110 is front lining connecting pin, the second arm body 120 it is outer Side is back bush connecting pin, and the steering connecting pin is equipped with mounting hole 200, for sphere knuckle, preceding lining to be fixedly mounted Set is equipped with circular casing 300 on connecting pin, and axis pin 400, axis pin 400 and circular bushing are equipped on the back bush connecting pin 300 coaxial arrangements, and axis pin 400 deviates from circular bushing 300 and extends axially outward setting, circular casing 300 and pin along place It is vertical two-by-two between the extending direction three of the axial direction of axis 400, the axial direction of mounting hole 200 and front lining connecting pin, it is such Structure so that the first arm body 110 and the second arm body are more secured, and the coaxial arrangement of circular casing 300 and axis pin 400 so that preceding Being more uniformly stressed between bushing and back bush in vehicle in use, distribution of force is uniform, can be reduced because unbalance stress is made Into the frictional dissipation of control arm body, so as to improve service life.

Above-mentioned axis pin 400 includes the insertion section 410 in the second arm body 120 and extends to expose the second arm body 120 The construction section of back bush connecting pin420, the insertion section 410 and 420 joining place of construction section are socketed with catch 500, the catch 500 are butted on the outside of the end of the second arm body 120.

As Figure 4-Figure 6, it is spaced for bushing configuration section 421, lining with catch 500 on the construction section 420 of axis pin 400 The extension 423 extended axially outside of configuration section 421 is covered for helicitic texture, and extension 423 is close to bushing configuration section 421 It is socketed with axle sleeve 422 on one side, embossed channels on 422 inner wall of axle sleeve, compared to common axis pin, this apparent axis pin of segmentation Installation position can be more accurately limited, and coefficient of friction is added by helicitic texture and embossed channels so that installation is more firm Gu and the setting of catch reduces the back bush of configuration to the active force of back bush connecting pin so that back bush connecting pin is not It is easy to crack.

Above-mentioned control arm body 100 be equipped with it is at least one with groove 140 that is invaginating to flanging homonymy, on groove 140 Equipped at least one shock relieve vent 150, the setting of groove 140 and shock relieve vent enhances the stress ability of control arm body 100 so that Control arm body 100 is unlikely to deform, while plays damping effect.

Above-mentioned control arm body 100 is molded by material QSTE380 integrated die-castings, circular 300 and first arm body 110 of bushing The welding of front lining connecting pin set, the welding setting of the circumferential surface of the insertion section 410 of axis pin 400 and the second arm body 120, catch 500 It welds and sets with the end face of back bush connecting pin so that the connection of each end in control arm body 100 is more secured, each End is unlikely to deform or occurs crack, adds endurance degree.

The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description Simply illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model is also Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed scope is defined by the appending claims and its equivalent thereof.
