Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present invention, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present invention structure expressed as Fig. 2, Fig. 3, diaphragm type spring brake chamber for a kind of truck braking system, comprise energy storage cylinder body 4, go up housing assy 6, and the connecting cover that described energy storage cylinder body 4 is connected with last housing assy 6, described going up in the housing assy 6 established push rod assembly 13, the one end is connected with the film place, the other end of described push rod assembly 13 stretches out described upward housing assy 6 and is connected with break, suit return spring on the described push rod assembly 13 is established energy storage piston and Parking spring in described energy storage cylinder body 4.
Be Parking chamber 15 in the described energy storage cylinder body 4; Described going up is driving chamber 16 in the housing assy 6.
The left side is for adjusting bolt among the figure.When adjusting nut and be in the A position, be in normal working, promptly can carry out braking, also can brake off; When the adjustment nut is in the B position, make product Parking chamber be in supply of material state (promptly can not brake), be convenient to entrucking.Adopt packing ring 10 sealings between the center of described energy storage piston and the adjustment bolt.
The diaphragm type spring brake chamber uses construction bolt to be fixed on the support, again by being connected with the adjustment arm in clevis.The adjustment bolt of afterbody screws on earth, comes holddown spring by tension energy storage piston.Make product Parking chamber be in supply of material state and be convenient to entrucking.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize improving the goal of the invention of reliability of products, the technological scheme that the present invention takes is:
The diaphragm type spring brake chamber of truck braking system provided by the invention, described energy storage piston comprises piston only 11 and piston rod 12, described piston only 11 and piston rod 12 are the riveted structure of split, and described piston only 11 is an aluminum alloy, and described piston rod 12 is a steel part.
Adopt technique scheme, the structure of existing product is carried out Transform Type design and update, reduce cost, improve performance, increased the dust guard of product, thus improve product performances such as reliability, anti-dust performance and endurance quality, the working life of having improved product; Simplify product structure, reduced the rate of fault of brake chamber.
Concrete structure of the present invention:
Threaded sleeve 1 is established in the bottom of energy storage cylinder body 4 of the present invention, and the center hole of described threaded sleeve 1 cooperates with the adjustment bolt, and described threaded sleeve 1 is provided with vent, and described vent will described 4 inside and outside connections of energy storage cylinder body.
Being positioned on the above-described vent set up defences on described energy storage cylinder body 4 aperture outward and protected sponge 9, and described protective sponge 9 is fixing by threaded sleeve shroud 8 chuckings.
The bottom shape of described energy storage cylinder body 4 is a little shallow grooves.
Described going up in the housing assy 6 set the dustproof collar 14 in position towards the end of break, and described positioning dust-proof collar 14 cooperates with described push rod assembly 13, and an end of described return spring is by described positioning dust-proof collar 14 location.
After product loading finishes, the adjustment bolt of afterbody is screwed working state.Loosen the Parking spring and make Parking chamber work output braking force.To the air inlet of Parking chamber, the energy storage piston moves compression Parking spring backward, removes parking braking when travelling.When needing parking braking the air pressure emptying of Parking chamber is got final product.When vehicle needed to brake in the process of moving, diaphragm promoted push rod assembly output braking force to inflation driving chamber, driving chamber, and vehicle is stopped.Emptying driving chamber gas can be removed service brake.
Working principle of the present invention:
The diaphragm type spring brake chamber is divided into the driving chamber and the Parking in the form of piston chamber of diaphragm type.The driving chamber obtains braking force by inflation, and vent gas has the driving return spring to get back to the brake off state again.The Parking chamber discharges output braking force by the Parking spring, inflates brake off to the Parking chamber.
Improvement of the present invention is as follows:
1, improves the Parking chamber and prevent dust, original structure is changed to new Parking chamber independence breathing structure.To be the logical outlet pipe of Parking chamber afterbody in the housing assy, can discharge gas Parking to the driving chamber to original structure when compressing.But this structure outlet pipe can not be stressed, often drops because of stressed.This structure is not because there is special filter medium, and long-time the use because of the truck poor working environment causes the Parking chamber to suck dust lost efficacy.Improve back two vents of processing on threaded sleeve,, outside threaded sleeve, install fixedly sponge of plastic sheath cover again additional at vent coated outside protective sponge.The good filtered air of energy after new the improvement, and appearance looks elegant is generous.
2, the energy storage piston is improved to by integrated type split type convenience is processed and the roughness that improved piston rod portion increases the durable of product.Original structure energy storage piston is the integral die-cast aluminum component, and improving the back is that die casting aluminum component piston only and the riveted joint of steel part piston rod form.Improve the consequent piston rod and be steel part and simple in structurely be convenient to Vehicle Processing and mill processing, can obtain very higher dimensional accuracy and roughness, the wearing and tearing to seal ring in the working procedure are littler.Improve the durability of products energy.
3, change the shape of energy storage cylinder body, original shape easy ponding when vertical the installation causes the water inlet of Parking chamber, and lost efficacy in the Parking chamber when temperature is lower than 0 ℃.Improvement back shape changes bottom groove to shoal has for a short time effectively avoided ponding, improves product reliability.
4, improving original dust-proof cover assembly is simple dustproof location collar, removes dust reduction capability for locating driving chamber return spring.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; or design of the present invention and technological scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
