Description
Technical field
The invention belongs to technical field of automobile parts, concretely, is a kind of vibration damper that is used on the automobile.
Background technique
Along with the level of urbanization improve constantly and people to the continuous pursuit of quality of the life, the car population of China is also constantly being climbed to a higher point, and has data to show, will reach 1.58 hundred million to the year two thousand twenty China car population.With 16.5 square metres of calculating of each car parking floor space, national parking occupation area will be up to 30.525 hundred million square metres.If the horizontal parking with present changes vertical parking into, then can save 2/3rds floor space, approximately can save 20.35 hundred million square metres parking area, can alleviate the nervous phenomenon of parking that China is about to appearance to a great extent.
As shown in Figure 1, for the air type vibration damper commonly used on the automobile, mainly form by upper bracket 1, undersetting 2, piston rod 3, piston 4, clutch release slave cylinder 5, oil sealing 6 etc.The lower end that the upper end is connected, piston 4 is solidly set on piston rod 3 of upper bracket 1 and piston rod 3, undersetting 2 links to each other with the bottom of clutch release slave cylinder 5.Piston 4 is arranged in the clutch release slave cylinder 5 that is full of hydraulic oil, and clutch release slave cylinder 5 is divided into upper cavity 5a and lower chamber 5b.Be provided with oil sealing 6 between the top of clutch release slave cylinder 5 and the piston rod 3, prevent that the hydraulic oil in the clutch release slave cylinder 5 from overflowing.The upper bracket 1 of vibration damper is connected to vehicle frame, and undersetting 2 is connected to axle near wheel.When wheel runs into the road surface and when causing spring compression and stretching of jolting, the energy of spring is delivered to vibration damper through upper bracket 1, and is delivered to piston 4 downwards via piston rod 3.Be equipped with pore 4a on the piston 4, when piston 4 moved up and down in clutch release slave cylinder 5, hydraulic oil can leak out through these pores 4a.Because these pores are very small, so under very big pressure, also can only there be hydraulic oil seldom to pass through.So just slowed down the movement velocity of piston, thereby movement of springs is slowly got off.
Yet because the repeated friction between oil sealing 6 and the piston rod 3, oil sealing 6 is easy to wearing and tearing; When automobile running, vibration damper is vertical installation on automobile, and hydraulic oil is contained in the clutch release slave cylinder 5, oil leakage phenomenon can not occur; In case vertical parking, vibration damper then are in horizontal state, hydraulic oil will overflow from the slit between oil sealing 6 and the piston rod 3, oil leakage phenomenon occur, be the common phenomenon that present vertical parking exists.
Summary of the invention
The object of the present invention is to provide a kind of vibration damper, when automobile is vertical when parking, the hydraulic oil in the vibration damper can not overflow from the slit between piston rod and the oil sealing.
For solving above technical problem; The telescopic shock absorber of the anti-leakage of oil of a kind of vertical parking provided by the invention; Comprise upper bracket (1), undersetting (2), piston rod (3), piston (4) and clutch release slave cylinder (5); The upper end of said piston rod (3) and upper bracket (1) are connected, and the lower end of piston rod (3) is stretched in the clutch release slave cylinder (5), and the lower end that said piston (4) is solidly set on piston rod (3) is divided into upper cavity (5a) and lower chamber (5b) with clutch release slave cylinder (5); Said undersetting (2) is installed in the bottom of clutch release slave cylinder (5); Be provided with oil sealing (6) between the top of clutch release slave cylinder (5) and the piston rod (3), it is characterized in that: the outside of said clutch release slave cylinder (5) is installed with oil storage storehouse (7), and this oil storage storehouse (7) communicates with clutch release slave cylinder (5) through the aperture of opening on the sidewall on clutch release slave cylinder (5) top (5c).
The vertical installation of vibration damper, when car is normally parked, not oil storage in the oil storage storehouse; During vertical parking, the upper end of vibration damper is downward-sloping gradually until horizontal, and the aperture of the hydraulic oil in the clutch release slave cylinder upper cavity on the clutch release slave cylinder sidewall flows in the oil storage storehouse, even the slit occurs between oil sealing and the piston rod, also do not have hydraulic oil and overflows.
The bottom in said oil storage storehouse (7) flushes with aperture (5c), and when car becomes when normally parking from vertical, all hydraulic oil in the oil storage storehouse can both come back to clutch release slave cylinder.
The outside as preferred said clutch release slave cylinder (5) is covered with dust-proof cover (8), and said oil storage storehouse (7) is welded on outside the dust-proof cover (8).
Beneficial effect: simple in structure, structure is ingenious, can on existing vibration damper, improve, and has solved effectively when automobile is vertical to be parked, the problem that the hydraulic oil in the vibration damper overflows has promotional value widely.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
The telescopic shock absorber of the anti-leakage of oil of vertical parking as shown in Figure 1 is made up of upper bracket 1, undersetting 2, piston rod 3, piston 4, clutch release slave cylinder 5, oil sealing 6 etc.The upper end of piston rod 3 and upper bracket 1 are connected, and the lower end of piston rod 3 is stretched in the clutch release slave cylinder 5, and piston 4 is solidly set on the lower end of piston rod 3, and piston 4 has been divided into upper cavity 5a and lower chamber 5b with clutch release slave cylinder 5.Be equipped with a plurality of pore 4a on the piston 4, when piston 4 moved up and down in clutch release slave cylinder 5, hydraulic oil can leak out through these pores 4a.Undersetting 2 is installed in the bottom of clutch release slave cylinder 5, is provided with oil sealing 6 between the top of clutch release slave cylinder 5 and the piston rod 3, and the above is identical with traditional telescopic shock absorber structural type, repeats no more at this.
Difference is: the outside of clutch release slave cylinder 5 is installed with oil storage storehouse 7, has aperture 5c on the sidewall on clutch release slave cylinder 5 tops, and oil storage storehouse 7 communicates with clutch release slave cylinder 5 through aperture 5c.The bottom in oil storage storehouse 7 preferably flushes with aperture 5c.
Further preferred as this programme, the outside of clutch release slave cylinder 5 is covered with dust-proof cover 8, prevents that impurity such as dust from getting into clutch release slave cylinder 5, influences the proper functioning of vibration damper, and oil storage storehouse 7 is positioned at outside the dust-proof cover 8, and welds together with dust-proof cover 8.
