Description
Technical field
This utility model relates to brake system of car, especially a kind of automobile pneumatic brake valve.
Background technology
Brake valve is the primary control in the middle of running braking system, at the braking procedure of double loop primary brake system
Sensitive servo antrol is realized with during release.The Chinese utility model of Publication No. CN2009427698Y discloses one
Automobile air brake valve assembly, including rustless steel piston bush, installing plate, upper valve body, dust-proof seal ring and lower valve body, this structure zero
Number of packages amount is many, and processing cost is high, and assembly difficulty is big, and is become housing by multiple separate assembling parts, the bulk strength of parts
Being difficult to ensure that, number of parts is many, and the contact surface between part is also the most corresponding to be increased, and the contact surface between each part seals and is also
One difficult problem the biggest.
Summary of the invention
This utility model solves the technical problem that and is to provide a kind of simple in construction, automobile pneumatic brake valve easy to assembly.
This utility model solves its technical problem and be the technical scheme is that a kind of automobile pneumatic brake valve, including upper valve
Body and lower valve body, include piston bush and dust-proof seal ring, described upper valve body, piston bush and dust-proof seal ring in described upper valve body
For integral type structure；Being provided with governor motion in described lower valve body, described governor motion includes drive link, inserts locking screw
Mother, spring base, spring and tip-lever support, described drive link lower end is connected with tip-lever support, and drive link upper end is provided with screw thread, and inserts is locked
Jack panel is threadeded with drive link, and inserts locking nut is connected with spring base, and spring base is provided with spring.
This utility model uses piston bush, upper valve body and dust-proof seal ring to be arranged to the scheme of integral structure, not only saves
About installing space, the minimizing of number of parts, greatly reduce the cost manufacturing and installing, and tie relative to split interconnection system
Structure, the mechanical property such as the intensity of integral structure is more preferable, and the contact surface sealing problem between brother's part also can well be solved
Certainly；Also eliminate piston bush the most relatively costly and because being easily deformed, and cause the impact of first piston hair fastener.
It is provided with first piston in described upper valve body, in lower valve body, is provided with the second piston, first piston and the second piston string
Connection.
Described upper valve body is provided with control mouth, air inlet and gas outlet, the described gas outlet phase controlling mouth and load sensing valve
Even；Described lower valve body is provided with lower air inlet, and lower gas outlet and air vent, equipped with acoustic filter on air vent.
Described lower valve body also includes guide holder and exhaust seat.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of a kind of automobile pneumatic brake valve of the present embodiment；
Fig. 2 is the structural representation of a kind of automobile pneumatic brake valve of the present embodiment.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
