Description

Automobile control arm assembly

Technical Field

The utility model relates to a part on vehicle chassis, concretely relates to car control arm assembly.

Background

The subframe is a framework of front and rear suspensions of the vehicle, and is connected to a "front frame" through the framework, and thus is conventionally called a subframe. One function of the auxiliary frame is to obstruct vibration and noise transmitted from the ground to the wheels and reduce the direct entering of the wheels into the carriage, and the other function is to connect, and the swing arm, the stabilizer bar and the steering mechanism are all fixed on the auxiliary frame. Generally, the left side and the right side of an automobile auxiliary frame are symmetrically connected with a swing arm assembly, and the other end of the swing arm assembly is connected with a brake hub bracket through a ball pin assembly. And the ball round pin subassembly structure on the swing arm assembly that has now generally includes parts such as spherical shell, protection casing, gland, a plurality of rand, spacing collar, gland, the structure is comparatively complicated, the assembly is loaded down with trivial details, improves the manufacturing cost of swing arm.

Disclosure of Invention

In order to solve the above problems, an object of the present invention is to provide a simple and reliable vehicle control arm assembly.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an automobile control arm assembly, includes the swing arm body, the swing arm body on be equipped with the mounting hole, install ball round pin subassembly in this mounting hole, ball round pin subassembly include ball round pin and rubber ring install the bearing in the rubber ring, bearing hole middle part be equipped with the narrow passageway that appears, be equipped with annular arc draw-in groove on this narrow passageway inner wall that appears, the rotatable setting in this arc draw-in groove of ball head portion position of ball round pin, the pore wall is the toper form respectively in the bearing between narrow passageway to the bearing hole both ends port.

The bearing comprises an inner ring and an outer ring, wherein one end of the inner ring is provided with an annular flange, and the flange shields a gap between the inner ring and the outer ring.

The outer wall of the rubber ring is provided with a limiting step, and the inner wall of the mounting hole is provided with a matching step matched with the limiting step.

The utility model discloses a structure of ball round pin subassembly has been simplified to this kind of structure, makes the ball round pin also can swing along bearing hole pivoted in, has reduced the cost of manufacturing and has improved the efficiency of installation, and the rubber ring provides the effect of shock attenuation buffering in addition, has just so realized the reliable technological effect of simple structure.

The invention is further described with reference to the accompanying drawings and the detailed description.

fig. 2 is a block diagram of a ball pin assembly according to an embodiment of the present invention.

Detailed Description

The present invention is described in detail below with reference to the following examples, which are only used for further illustration of the present invention, and should not be construed as limiting the scope of the present invention.

As shown in fig. 1 and fig. 2, the embodiment discloses an automobile control arm assembly, including swing arm body 1, be equipped with mounting hole 2 on swing arm body 1, install ball round pin subassembly 3 in this mounting hole 2, ball round pin subassembly 3 includes ball round pin 31 and rubber ring 32, install bearing 33 in rubber ring 32, bearing 33 hole middle part is equipped with narrow shape passageway 4, be equipped with annular arc draw-in groove 41 on this narrow shape passageway 4 inner wall, rotatable setting in this arc draw-in groove 41 of ball head portion position 311 of ball round pin 31, the hole wall is opened in the bearing 33 between narrow shape passageway 4 to the bearing 33 hole both ends port and is toper form 5 respectively and opens the amplitude of oscillation that improves the ball round pin.

The bearing 33 includes an inner ring 331 and an outer ring 332, and the inner ring 331 has an annular flange 3311 at one end thereof, and the flange 3311 shields a gap between the inner ring 331 and the outer ring 332. The structure can prevent dust from entering the bearing 33 to affect the rotation of the inner ring 331, thereby improving the reliability of the structure, and the circumferential wall of the inner ring 331 is provided with a telescopic groove (not shown) arranged along the length direction, when the ball pin 31 is assembled, the inner hole of the inner ring 331 is opened through the telescopic groove, so that the ball head part of the ball pin 31 is placed in the arc-shaped clamping groove 41 in the inner hole, and then the steel ball 333 and the outer ring 332 are assembled to complete the assembly of the bearing 33 and the ball pin 31.

The outer wall of the rubber ring 32 is provided with a limit step 321, and the inner wall of the mounting hole 2 is provided with a matching step matched with the limit step 321. Such a structure can further improve the reliability of the installation of the rubber ring 32.

Through the technical scheme, the structure of the ball pin assembly 3 is simplified, the ball pin 31 can swing along the inner hole of the bearing 33 when rotating, the manufacturing cost is reduced, the installation efficiency is improved, and in addition, the rubber ring 32 provides a damping and buffering effect, so that the technical effect of simple and reliable structure is realized.
