Embodiment
In order that those skilled in the art is better understood when the technical solution of the utility model, below in conjunction with accompanying drawing
The utility model is further detailed.
As shown in Figure 2 and Figure 5, the utility model embodiment provides a kind of Assembly of pin, includes the bearing pin body 1 and one of column
The plastic sleeve 2 that end seal is closed, the blind end of the axle sleeve 2 is provided with from the outwardly directed gear platform 3 of outer wall, the opening of the axle sleeve 2
End is provided with the interior Access Division 4 inwardly stretched out from inwall and from the outwardly directed outer Access Division 5 of outer wall, and the bearing pin body 1 is located at institute
State in axle sleeve 2 and abutted with the interior Access Division 4.
In the Assembly of pin of the utility model embodiment, axle sleeve 2 is made up of plastic material, and bearing pin body 1 is contained in into axle
Set 2 in, it is to avoid bearing pin body 1 is directly contacted with the brake pedal arm 9 and booster shift fork 8 of cooperation, but by plastic sleeve 2 with
The two metal pieces into contact, can be prevented effectively from brake pedal arm 9 and produce friction abnormal sound with booster shift fork 8, in addition by setting
The mounting hole for putting outer Access Division 5 and booster shift fork 8 coordinates to carry out the anticreep of Assembly of pin, compared to riveting of the prior art
Anticreep is followed closely, assembles more simple, assembles and disassembles also more convenient.
On the basis of said structure, the lower end of the interior Access Division 4 and the outer Access Division 5 passes through the first connection respectively
Portion 6 and second connecting portion 7 are connected with the openend, and the first connecting portion 6 and the second connecting portion 7 are along the openend
It is circumferentially distributed, slot is provided between the first connecting portion 6 and the second connecting portion 7.By interior Access Division 4 and outer Access Division 5
It is connected by independent first connecting portion 6 and second connecting portion 7 with openend, and in first connecting portion 6 and second connecting portion 7
Between slot is set, be conducive in installation process, it is to avoid first connecting portion 6 and second connecting portion 7 are interfered, can be independent
Access Division 4 and the relative position of bearing pin body 1 and outer Access Division 5 and the relative position of the mounting hole of booster shift fork 8 in adjustment, with
Make the outside for being connected to the mounting hole of booster shift fork 8 that Assembly of pin is more reliable, effectively prevent Assembly of pin from departing from booster and dialling
Fork 8.
In order to further prevent the Assembly of pin of the utility model embodiment from coming off in use, first connection
Portion 6 and the second connecting portion 7 are circumferentially alternately uniformly distributed along the openend, in installation process, first pass through the first connection
Portion 6 is coordinated interior Access Division 4 and bearing pin body 1, then is adjusted outer Access Division 5 by second connecting portion 7 and pacified with booster shift fork 8
The assembly precision in hole is filled, in addition, the highly preferred height less than outer Access Division 5 of interior Access Division 4, further to prevent interior clamping
Portion 4 and outer Access Division 5 and first connecting portion 6 the interfering in installation process with second connecting portion 7.
