Abstract
The utility model relates to an automobile brake valve which comprises an upper shell, a lower shell, an upper cover, and a handle, wherein, the handle is connected with an upper cam, a lower is corresponding to the upper cam and is positioned in the upper shell, a return spring is positioned between a lower end surface of the lower cam and a piston spring seat, and a balance spring is arranged between the piston spring seat and a piston. The utility model is characterized in that a push rod is fixed on the bottom end of the lower cam, and the bottom end of the push rod is an R surface and is connected and engaged with an air in and air outlet valve gate. The utility model has good sealing property, high reliability, good follow-up property, and long service life. Output air pressure is full air pressure output. The automobile can be braked and relieved rapidly. The utility model can be used for the parking and the emergency braking of automotive vehicles.
Description
The utility model belongs to self-propelled vehicle braking components and parts, relates generally to brake valve of car.
The vehicle manual brake activation valve of prior art, owing to adopt balance spring formula structure, damming appears in output pressure, air pressure output entirely, cause dual circuit trailer braking valve two chamber air pressure overbalances, cause the trailer self-actuating brake, cause oil plant waste and components and parts accelerated wear test.And because the structure that the intake and exhaust valve adopts is " 8 " font, its rubber easily wears out and comes off, and has influenced the leak tightness and the reliability of product, influences the rapid braking and the releasing of automobile.Its air inlet aperture, exhaust aperture are owing to be subjected to the effect of balance spring, and aperture is too small, also influences the rapid braking and the releasing of automobile.
The hand brake valve that it is full air pressure output that the purpose of this utility model provides a kind of good airproof performance, reliability height, output pressure, make automobile brake rapidly and to remove.
The utility model comprises upper shell, lower house, loam cake and handle, handle is connected with overhead cam, following cam is relative with overhead cam and be positioned at upper shell, pull back spring is between the lower surface and piston spring seat of following cam, balance spring is arranged between piston spring seat and the piston, it is characterized in that cam bottom fixed mandril down, the push rod bottom is designed to the R face, engages with the intake and exhaust valve.
In its upper shell annular groove is set, back-up ring is installed in the annular groove, the piston spring seat that balance spring supports contacts with the back-up ring lower surface.Ring recess is set on the overhead cam, places the O RunddichtringO, upper shell inside face and overhead cam are fitted and are sealed.The lower house upper surface is provided with " ∞ " font groove and induction opening, places seal ring in the groove, and upper shell and lower house are fitted and formed static seal.The outside face of loam cake and upper shell is an equilateral polygon.Following cam and push rod are structure as a whole.
The utlity model has: good airproof performance, reliability height, life-span length, output pressure are full air pressure output, automobile can be braked rapidly and remove.Increasing balance spring rigidity and up and down in the cam amount of moving down, making the bar handle corner little, follow-up action is good.By increasing the O RunddichtringO between overhead cam and the upper shell, the O RunddichtringO between piston and the lower house, push rod adopt R face structure to engage with the intake and exhaust valve, guarantee seal request.The Parking and the emergency braking that can be widely used in various power actuated vehicles.
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing is the structural representation of the utility model embodiment:
Among the figure, under the driving situation, piston 6 self-balancings, and by descending cam 9 bonded assembly push rods that intake and exhaust valve 5 is often opened, pressurized air from air receiver is entered in 25 chambeies by 22 chambeies, air inlet aperture 23 through admission port 1, enter into brake application by spring air chamber and dual circuit trailer braking valve through air extractor duct 2 again, remove main car spring braking and trailer braking protection valve, guarantee the full air pressure output of bleed pressure, thereby solved the self-actuating brake problem of dual circuit trailer braking valve.Glancing impact, driving handle 11 drives overhead cam 12 cam 9 is moved under the combined action of pull back spring 8 and air pressure, and push rod and intake and exhaust valve 5 break away from, and piston 6 is closed with intake and exhaust valve 5, and keeps servo-actuated.The air pressure of brake application by spring air chamber passes through 25 chambeies, exhaust aperture 24 from exhausr port 3 exhaust to atmospheres by air extractor duct 2, makes automobile brake.During brake off, handle 11 is in the initial position, following cam 9 moves down, compression retracteding position spring 8, cross admission port 1 from the next Pneumatic pipe cleaner of air receiver and enter 22 chambeies, and act on piston 6 and the intake and exhaust valve 5, overcome the effect of balance spring 7, piston 6 keeps servo-actuateds with intake and exhaust valve 5, moves on together, and at this moment push rod is opened intake and exhaust valve 5,22 chamber Pneumatic pipe cleaners are crossed air inlet aperture 23 and are entered 25 chambeies, and enter the brake application by spring air chamber by air extractor duct 2, and make the push rod return of brake application by spring air chamber, remove automobile brake.Loam cake 13 and upper shell 14 are octagon, can cooperate to realize the location, and loam cake can not arbitrarily be rotated on upper shell.O RunddichtringO 10 in overhead cam 12 grooves can guarantee to keep when overhead cam comes back rotation sealing.Be installed in the miles of relative movement of cam 9 and piston spring seat 16 under 15 qualifications of back-up ring of upper shell inside face.There is seal ring 17 to seal between upper shell 14 and the lower house 18, in the hole of lower house 18, is installed into drain tap 5, air inlet and exhaust valve spring perch 20, air inlet and exhaust valve door spring 4, piston 6 and O RunddichtringO 19 and 21.
