Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-6, a kind of air booster, including cylinder 1 are please referred to, the side of cylinder 1 is connected with hydraulic cylinder 5, hydraulic cylinder 5
On oil storage cup 2 is installed, the oil outlet of hydraulic cylinder 5 is equipped with connector 3, and the side of connector 3 is connected with end cap 4, hydraulic
It is to be threadedly coupled between cylinder 5, connector 3 and end cap 4, offers corresponding first oil transportation respectively on connector 3 and end cap 4
Hole 9 and the second oil transportation hole 8, are formed with oil-control cavity, the inside of the oil-control cavity is equipped with rubber between connector 3 and end cap 4
The surface of cap 11, rubber cap 11 is recessed inwardly, and the inside of rubber cap 11 offers and 8 phase of the first oil transportation hole 9 and the second oil transportation hole
Corresponding third oil transportation hole 13, the surface of rubber cap 11 integrally formed with equally distributed rubber strip 15, rubber strip 15 two-by-two it
Between be each formed with oil transportation gap, the inside of rubber cap 11 is inlaid with oil-control piece 14, and the surface of oil-control piece 14, which offers, to be uniformly distributed
The 4th oil transportation hole 12, and the 4th oil transportation hole 12 is dislocatedly distributed with third oil transportation hole 13, and the side of oil-control piece 14 is provided with reset
Spring 10, the both ends of reset spring 10 are abutted with oil-control piece 14 and connector 3 respectively, and the second oil transportation hole 8 on end cap 4 passes through brake
Vehicle pipe 6 is connect with caliper 7, and the first oil transportation hole 9 is connected to hydraulic cylinder, and the second oil transportation hole is connected to brake pipe.
When brake for the first time using the present apparatus, brake pedal is trampled, air pressure is by flowing oil storage cup 2 after cylinder 1
Oil in inlet hydraulic cylinder 5 is pushed by brake pipe 6 into caliper 7, when oil is entered inside connector 3 by the first oil transportation hole 9
Later, the 4th oil transportation hole 12 that oil passes through on oil-control piece 14 separates rubber cap 11 with oil-control piece 14, due to rubber cap 11
Surface be recessed inwardly, therefore when rubber cap 11 by oil extruding after can expand outwardly, as shown in figure 5, at this time oil entrance
It is then flowed into the second oil transportation hole 8 on end cap 4 by third oil transportation hole 13 between oil-control piece 14 and rubber cap 11, finally by
Brake pipe 6 flows into caliper 7, and when the pressure in brake pipe 6 reaches 12.5 megapascal, caliper 7 is by engineering loader system
Dynamic, the pressure in brake pipe 6 increases from zero to 12.5 megapascal and probably needs 1.5 seconds.
When first time, end of braking was loosened the brake, since the pressure in brake pipe 6 is greater than the pressure in hydraulic cylinder 5
Power, therefore the oil in brake pipe 6 can start to flow back, oil is entered in oil-control cavity by the second oil transportation hole 8 on end cap 4, and oil is logical
It crosses the third oil transportation hole 13 on rubber cap 11 and squeezes oil-control piece 14 later, toward oil-control cavity after oil-control piece 14 is by the extruding of oil
The mobile simultaneously pressed home spring 10 in middle part, reset spring 10 is shunk under the promotion of oil-control piece 14, at this time in oil-control piece 14
The backflow gap of oil is reserved between rubber cap 11, most oil is flowed back by the 4th oil transportation hole 12 on oil-control piece 14, by
It is recessed inwardly in the surface of rubber cap 11, therefore partial oil can be to external diffusion when by rubber cap 11, the oil that spreads out
It will push rubber cap 11 and separate rubber cap 11 with end cap 4, the oil then spread out can be by defeated on 11 edge of rubber cap
Oil-gap flows back, and with oily gradual reflux, the pressure in brake pipe 6 is gradually reduced, and pushes away in the elastic force of reset spring 10
Under dynamic, oil-control piece 14 and rubber cap 11 are gradually pushed back, and the backflow gap between oil-control piece 14 and rubber cap 11 is gradually reduced, rubber
Capsule 11 is also gradually bonded with end cap 4 again, when the elastic force of pressure and reset spring 10 in brake pipe 6 keeps balancing, oil
It can stop flowing back, certain oil pressure can be retained in brake pipe 6 at this time, people can be by adjusting the coefficient of elasticity of reset spring 10
Pressure in brake pipe 6 is adjusted to about 3 megapascal, therefore when people carry out secondary braking, being equivalent to will be in brake pipe 6
Pressure is initially increased to 12.5 megapascal from 3 megapascal, and the time required for braking is about 1.1-1.3 seconds, so as to shorten system
The dynamic time accelerates the speed of braking.
In conclusion the air booster, by having added connector 3 and end cap 4 between hydraulic cylinder 5 and brake pipe 6,
And reset spring 10, oil-control piece 14 and rubber cap 11 are provided between connector 3 and end cap 4, when being braked,
The amount of oil reflux can be reduced, certain oil pressure can be saved in brake pipe 6 can so as to shorten the time of brake
The speed for accelerating brake, improves the sensitivity of brake.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
