Abstract
The utility model relates to an air booster bump and belongs to the technical field of braking of engineering machinery. The air booster bump consists of an air chamber cylinder body and a hydraulic cylinder body, wherein a push rod assembly is arranged in the air chamber cylinder body; one end of the push rod assembly is connected with a piston in the hydraulic cylinder body; the piston is arranged in the hydraulic cylinder body; one end of the piston is provided with a taper; and an oil injection hole is formed on the surface of the piston and connected with an oil cup assembly. According to the air booster bump, a breathing air bag membrane is arranged on the oil cup assembly, and air slots are formed on the inner wall of an oil cup cap, so that oil is freely fed and returned, and a phenomenon that a braking solution is spray out is avoided; the hydraulic cylinder body and the hydraulic piston are made of high-strength aluminum alloy instead of the conventional HT200 pig iron casting, so that blocking and clamping phenomena due to rust are avoided, and a phenomenon that a sealing piece fails due to wear is avoided; and a cold extrusion process is adopted by the hydraulic cylinder body, so that the hydraulic cylinder body is high in accuracy, and the service life is greatly prolonged.
Description
Technical field
The utility model relates to a kind of air booster pump, belongs to the braking technology field of construction machinery and equipment.
Background technology
The air booster pump is to introduce the production of domesticizing of the U.S.'s Caterpillar construction machinery and equipment eighties in 20th century, in actual use; Because the bad working environments environment of loader, frequent braking requires high to this reliability of products; And original design exists oil cup cap to scurry oil, and hydraulic cylinder, hydraulic piston corrosion are blocked, stuck phenomenon; The hydraulic packing leather cup damages, and block structure is unreasonable, can't reach antisoiling purpose.
Summary of the invention
To the problems referred to above that exist in the prior art, the utility model provides a kind of air booster pump of function admirable.
The technical scheme that the utility model adopts is following:
The air booster pump is characterized in that, is made up of air chamber cylinder body and hydraulic cylinder, is provided with push rod assembly in the said air chamber cylinder body, and an end of said push rod assembly is connected with the interior piston of hydraulic cylinder; Said piston places in the hydraulic cylinder, and an end of said piston has a tapering, and said piston face is provided with oil hole, and said oil hole connects the lubricating cup assembly.
Further, said air chamber cylinder body and hydraulic cylinder are through bolted connection, and the position that contacts simultaneously is provided with seal ring.
Further, said lubricating cup assembly is cylindric cup, and said lubricating cup assembly inwall is provided with the air bag thin slice, and the top cover of said lubricating cup assembly is provided with the air drain with air communication.
Further, the material of said hydraulic cylinder and piston is aluminum alloy.
Further, said hydraulic cylinder is provided with the oiling assembly.
The utility model air booster pump is compared with air booster pump of the prior art, and its beneficial effect shows:
1, lubricating cup assembly design breathing bag diaphragm, and oil cup cap inwall air drain, both guaranteed, oil return freely, stopped braking liquid ejection phenomenon again.
2, hydraulic cylinder, hydraulic piston are improved to high strength aluminum alloy by former HT200 iron casting, avoided because of retardance that corrosion causes, stuck, and sealing part abrasion and losing efficacy, and hydraulic cylinder uses cold-extrusion technology, and precision is high, has greatly improved service life.
3, air chamber cylinder body and hydraulic cylinder adopt upper and lower bolted connection, and increase seal ring, have prevented that effectively air chamber lost efficacy because of contamination by dust.
4, piston adopts the sealing of rigidity awl, and along with the pressure of hydraulic cavities increases, sealing effectiveness is good more, has both avoided rubber valve directly to be hit, and has played the effect of double insurance leak free again, and reliability, durability are better.
5, aluminium alloy compression casting any surface finish, plastic-blasting is handled rust protection, in light weight, easy to assembly.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that utility model is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.

The specific embodiment
See also Fig. 1 and 2, the air booster pump is made up of air chamber cylinder body 4 and hydraulic cylinder 3.
Be provided with push rod assembly 1 in the air chamber cylinder body 4, an end of push rod assembly 1 is connected with hydraulic cylinder 3 interior pistons 10.
Piston 10 places in the hydraulic cylinder 3, and an end of piston 10 has a tapering, and piston 10 surfaces are provided with oil hole, and oil hole connects lubricating cup assembly 8.
Lubricating cup assembly 8 is cylindric cup, and lubricating cup assembly 8 inwalls are provided with air bag thin slice 9, and the top cover of lubricating cup assembly 8 is provided with the air drain 7 with air communication.
Air chamber cylinder body 4 is connected through bolt 6 with hydraulic cylinder 3, and the position that contacts simultaneously is provided with seal ring 5.
The material of hydraulic cylinder 3 and piston 10 is aluminum alloy.
Simultaneously, hydraulic cylinder 3 is provided with oiling assembly 11, is used for replenishing hydraulic oil in the hydraulic cylinder 3.
The utility model air booster pump after the design of employing said structure, along with increasing of air chamber cylinder body 4 air pressure, promotes piston 10 and in hydraulic chamber 2, moves, thereby plays the effect of hydraulic braking.The air booster pump, its form is an air over hydraulic, is applicable to engineering truck brake system such as loader, excavating machine, roller, its effect is to change infrabar into high hydraulic pressure to guarantee brake request.
Above content only is to be given an example and explanation to what the utility model structure did; Under the technical personnel in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the design of utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
