Description
Technical field
This utility model is related to auto parts and components field, particularly a kind of rear overhang rack swing arm assembly.
Background technology
Automobile swing arm assembly vehicle frame with car relatively between important bindiny mechanism, typically may be used according to different suspension swing arm bindiny mechanisms
To be divided into independent suspension and rigid axle suspension, independent suspension derives wishbone-type independent suspension, double trailing arm type independent suspension again
Etc. several suspension fork mechanisms.Automobile runs into rainy day, on heavy road face when it is necessary to ensure that its automobile swing arm assembly can have good
Good sealing, however, existing dust cover not only assembly or disassembly inconvenience；And fixed effect is not very good, makes for a long time
With afterwards, dust cover is easy to loosen, so that the sealing property of dust cover is not fine, leads to part dust to enter interior
Portion, the normal work of impact ball pin.
Content of the invention
The purpose of this utility model is intended to solve the deficiency of prior art problem, provides a kind of rear overhang rack swing arm total
Become.
For reaching above-mentioned purpose, this utility model is to implement according to technical scheme below:
A kind of rear overhang rack swing arm assembly, including ball seat shell and the swing arm being connected on ball seat shell, ball seat shell
Inside be provided with ball seat, bulb be installed in ball seat, ball seat bottom is provided with catch, catch is welded with ball seat outer casing bottom, ball seat and
Dust cover is installed between ball stud, described dust cover upper end is provided with the upper shed for connecting ball head pin, and dust cover lower end sets
There is the under shed for connected ball seat shell, described upper shed inwall is provided with female thread, and upper shed outer wall is provided with annular groove, institute
State under shed inwall and be provided with annular slot, described under shed outer wall bottom is provided with a circle annular protrusion.
Further, described swing arm is made up of adapter assembly, connecting screw rod, flange surface nut and bush of swing arm, joint group
Part one end is connected on ball seat shell, and the adapter assembly other end is connected to one end of connecting screw rod by flange surface nut, connects
The screw rod other end is also connected with flange surface nut, and the end of the connecting screw rod other end connects bush of swing arm.
Compared with prior art, rear overhang rack swing arm assembly of the present utility model, the female thread of the upper shed of dust cover
Enter with can effectively prevent dust after connecting ball head pin connection, due to the annular slot effect under shed, under shed
Two sides formed two snap rings, make under shed have two sections of sealing effectiveness when with ball seat cage connection, thus reaching higher
Sealing effectiveness, the annular protrusion outside under shed ensure that dust cover, when blocking ball seat shell pilot hole, provides enough clampings
Strength；Therefore, this utility model considerably increases stability and the service life of rear overhang rack swing arm.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of dust cover of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is further described to this utility model, in the signal of this utility model
Property embodiment and explanation be used for explaining this utility model, but be not intended as to restriction of the present utility model.
A kind of rear overhang rack swing arm assembly as shown in Figure 1 and Figure 2, including ball seat shell 5 be connected to ball seat shell 5
On swing arm, be provided with ball seat 7 in ball seat shell 5, bulb 9 be installed in ball seat 7, ball seat 7 bottom is provided with catch 6, catch 6 with
Ball seat shell 5 bottom welding, is provided with dust cover 8 between ball seat 7 and bulb 9 pin, described dust cover 8 upper end is provided with for connecting
The upper shed 801 of ball stud, dust cover 8 lower end is provided with the under shed 802 for connecting ball seat shell 5, in described upper shed 801
Wall is provided with female thread 803, and upper shed 801 outer wall is provided with annular groove 804, and described under shed 802 inwall is provided with annular slot
806, described under shed 802 outer wall bottom is provided with a circle annular protrusion 805, the operation principle of dust cover 8: upper shed 801 interior
Can effectively prevent dust from entering after screw thread 803 and bulb 9 pin connection, because the annular slot 806 under shed 802 acts on,
Two sides under shed 802 forms two snap rings, makes under shed 802 have two sections of sealing effects when being connected with ball seat shell 5
Really, thus reaching higher sealing effectiveness, the annular protrusion 805 outside under shed 802 ensure that dust cover 8 is blocking outside ball seat
During shell 5 pilot hole, provide enough clamping strength.Described swing arm is by adapter assembly 4, connecting screw rod 3, flange surface nut 2 and swing arm
Bushing 1 forms, and adapter assembly 4 one end is connected on ball seat shell 5, and adapter assembly 4 other end is connected to by flange surface nut 2
One end of connecting screw rod 3, connecting screw rod 3 other end is also connected with flange surface nut 2, and the end of connecting screw rod 3 other end connects
Bush of swing arm 1.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every according to skill of the present utility model
The technology deformation that art scheme is made, each falls within protection domain of the present utility model.
