The utility model discloses a be equipped with circular cone compression spring between first spring holder and the second spring holder, turn shallow shell party with the big one end of circular cone compression spring diameter, make brake chamber during operation safe and reliable more, increased circular cone compression spring's incorruptibility simultaneously.
Description
Technical field
The utility model belongs to automotive brake technical field, relates to brake chamber assembly before a kind of break.
Background technique
Authorization Notice No. CN203879987U discloses air chamber assembly before a kind of break, and push rod disclosed in it is provided with return spring, and this return spring is straight line type, and its two ends are directly connected with inside fixing frid and dark shell.Above-mentioned design is when brake chamber works, and Security, reliability Shortcomings, have to be hoisted, and the working life of return spring is short simultaneously, has the problem of durability deficiency.
Model utility content
The purpose of this utility model is to overcome prior art defect, provides one more safe and reliable, increases the front brake chamber assembly of spring durability simultaneously.
The purpose of this utility model can be achieved through the following technical solutions:
Front brake chamber assembly, comprises and carries out the dark shell that engages and shallow shell by clip, and dark shell and shallow shell neutral position are through there being push rod, and described push rod is through the second spring seat and the first spring seat; Circular cone Compress Spring is provided with between the first described spring seat and the second spring seat; Described circular cone compression spring housing is located on push rod; One end that described circular cone compression spring diameter is large is positioned at the first spring seat.
The first described spring seat is located at fixing frid inner side surface neutral position, and fixing frid is located at rubbery membrana dermalis inner side surface neutral position, and rubbery membrana dermalis is located on shallow shell inner side surface.
The second described spring seat is located at dark shell inner side surface neutral position.
The side of described dark shell is evenly provided with bolt, and bolt head side is positioned at inside dark shell, and its side is combined with nut, and the bolt between nut and dark shell is provided with stiffening plate and backing plate.
The beneficial effects of the utility model: the utility model is by being provided with circular cone Compress Spring between the first spring seat and the second spring seat, circular cone is compressed the large one end of spring diameter and turn shallow shell one side, more safe and reliable when brake chamber is worked, add the durability of circular cone Compress Spring simultaneously.
