Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with attached drawing and specific implementation
The utility model is described in detail in example.
The utility model is more for vacuum booster installation part and pin shaft moves left and right so that stepping on production when brake pedal
The problem of raw noise, provides a kind of pin shaft structure and automobile.
As shown in Figures 1 to 4, the utility model embodiment provides a kind of pin shaft structure, applied to brake pedal arm 20 and very
The installation of empty booster fork 30, comprising:
With the key seat 11 and axis body 12 of center line setting；
With the extension 13 of 11 integrally connected of key seat, card is provided on the extension 13 and sets slot 14；
Wherein, it is inserted in by the axis body 12 opposite on the brake pedal arm 20 and the vacuum booster fork 30
In the mounting hole answered, the brake pedal arm 20 is connected with the vacuum booster fork 30, and the card sets slot 14 and true
The empty card of booster push rod 31 sets connection.
Specifically, mounting hole is passed through for the ease of the axis body 12, the end diameter of axis body 12 is slightly less than upper end diameter.
By setting a global facility for pin shaft 10, vacuum booster installation amount of parts and simplification can be reduced
Assembly technology.
10 or so play of pin shaft when braking in order to prevent reduces brake noise, and reduces brake pedal arm 20 to pin shaft 10
Impact, need on axis body 12 be arranged rubber ring 15.
Specifically, it is provided with an annular mounting groove on the axis body 12, prolongs the centerline direction of the axis body 12, the peace
The width of tankage is identical as the thickness of the brake pedal arm 20.Rubber ring 15 is provided in the mounting groove.Mounting groove is set
Position-limiting action can be played to rubber ring 15 by setting, to prevent rubber ring 15 from falling off.
It should be noted that distance of the rubber ring 15 apart from key seat 11 is identical as the thickness of vacuum booster fork 30, it will
After axis body 12 sequentially passes through the mounting hole of vacuum booster fork 30 and brake pedal arm 20, brake pedal arm 20, which is located at, to be provided with
The position of rubber ring 15, and 15 width of rubber ring is also identical as the thickness of brake pedal arm 20, in this way, when trampling brake pedal
When, brake pedal arm 20 will not directly be contacted with axis body 12, to reduce the impact to axis body 12, reduced noise, extended pin shaft
10 service life.
