Description of the drawings
Fig. 1 is the overall structure sectional view of the utility model embodiment
Fig. 2 is the cylinder body of the utility model embodiment and front and back cylinder cap connection relationship diagram
Specific implementation mode
The utility model is illustrated in the following with reference to the drawings and specific embodiments.
Referring to Figures 1 and 2：
The front and back end of a kind of band-type brake oil cylinder, including cylinder body 1, cylinder body 1 is installed with front end housing 2 and back cylinder cover 3 respectively.
The front and back cylinder chamber 101 communicated is equipped in cylinder body 1.
Front end housing 2 is equipped with the preceding center oilhole 201 being connected to cylinder chamber 101 and the front end fourth with the preceding center oilhole 201
The advance oil outlet 202 that word connection, both ends are communicated with the external world.
Back cylinder cover 3 be equipped with connection cylinder chamber 101 and the external world rear center's oilhole 301 and with 301 cross of rear center's oilhole
The laggard oil outlet 302 that connection, both ends are communicated with the external world.
Piston 4 capable of sliding back and forth is equipped in cylinder chamber 101, piston 4 is equipped with piston rod 5.
Piston rod 5 is actively plugged in rear center's oilhole 301 on back cylinder cover 3, and the rear part is exposed to except back cylinder cover 3.
For the front plugged and fixed of piston rod 5 in the central through hole of piston 4, front end protrudes from the front of piston 4.
The front end of piston rod 5 is equipped with can be in and out of the precentrum of preceding center oilhole 201.
Being nested and fixed on the piston rod 5 at 4 rear of piston can move forward and backward with bar and after rear center's oilhole 301
Tapered sleeve 6.
Be additionally provided on front end housing 2, rear and front end parallel with preceding center oilhole 201 respectively with advance oil outlet 202 and cylinder
The preacceleration oilhole 203 that chamber 101 is connected to, being equipped with when being opened in the oil inlet of oil cylinder front end, being fuel-displaced in the preacceleration oilhole 203 closes
The preceding check valve 7 closed；
Back cylinder cover 3 be equipped with, rear and front end parallel with rear center's oilhole 301 respectively with cylinder chamber 101 and laggard oil outlet
The rear acceleration oilholes 303 of 302 connections, equipped with being closed when can be opened in the oil inlet of oil cylinder rear end, is fuel-displaced in rear the accelerations oilhole 303
Rear check valve 8.
The operation principle of the utility model is：When the oil inlet of oil cylinder rear end, preceding check valve 7 is closed, and rear check valve 8 is opened.Outside
The high pressure oil on boundary accelerates oilhole 303 to rapidly enter 101 rear portion of cylinder chamber after passing through, driving piston 4 travels forward, and piston 4, which drives, lives
Stopper rod 5 travels forward, and the high pressure oil of 101 front of squeeze cylinder chamber is discharged along preceding center oilhole 201.When piston 4 and piston rod 5 are transported
Row to the trip latter end when, before the precentrum of 5 front end of piston rod enters in center oilhole 201, due to check valve 7 before at this time
It closes, the remaining high pressure oil in 101 front of cylinder chamber is only capable of the discharge of the gap between precentrum and preceding center oilhole 201 so that cylinder
The Extraction rate of 101 front of chamber be slower than the rear part into speed oil, the high pressure oil of stagnant row forms reversely piston 4 in cylinder chamber 101
Active force, 4 speed of service of piston slow down, and under the cushioning effect with 2 gentle touchdown of front end housing.
When the oil inlet of oil cylinder front end, preceding check valve 7 is opened, and rear check valve 8 is closed.Extraneous high pressure oil passes through preacceleration oilhole
203 rapidly enter 101 front of cylinder chamber, and driving piston 4 moves backward, and piston 4 drives piston rod 5 to move backward, and squeeze cylinder chamber
The high pressure oil at 101 rear portions is discharged along rear center's oilhole 301.When piston 4 and piston rod 5 are run to the latter end of the trip, piston
Rear tapered sleeve 6 on bar 5 enters in rear center's oilhole 301, since rear check valve 8 is closed at this time, the remaining height in 101 rear portion of cylinder chamber
Pressure oil is only capable of the discharge of the gap between rear tapered sleeve 6 and rear center's oilhole 301 so that the Extraction rate at 101 rear portion of cylinder chamber is slower than
Its front into speed oil, the high pressure oil of stagnant row forms opposition to piston 4 in cylinder chamber 101, and 4 speed of service of piston subtracts
Slowly, and under the cushioning effect with 2 gentle touchdown of back cylinder cover.
