Abstract

The utility model discloses a clutch booster. The clutch booster comprises a push rod and a booster shell body with two open ends, wherein a hydraulic cylinder piston is arranged in the booster shell body, and the push rod is connected with one end of the hydraulic cylinder piston. An inner cavity of the booster shell body is divided into a hydraulic cylinder and a pneumatic cylinder by the hydraulic cylinder piston, wherein an air cylinder piston and reset springs are arranged in the pneumatic cylinder, and a side cylinder provided with a relay piston is arranged on the outer side of the pneumatic cylinder. The hydraulic cylinder piston is fixedly connected with the air cylinder piston, and the hydraulic cylinder piston is surrounded by the reset springs. The hydraulic cylinder piston is fixedly connected with the air cylinder piston to form an integrated piston, so that the clutch booster ensures that no gap exists between the hydraulic cylinder piston and the air cylinder piston in an operation process and eliminates impact and abnormal sound; the hydraulic cylinder piston is surrounded by the reset springs, so that the effect that the pistons are free of eccentric wear and oil leakage is ensured.

Description

A kind of clutch booster
Technical field
The utility model relates to automotive field, particularly the clutch booster field.
Background technique
Lighter for the separation or the joint that make clutch, generally between clutch and clutch master cylinder, clutch booster is installed.The cylinder piston of clutch booster commonly used and liquid cylinder piston are generally split-type structural and Returnning spring is external, easily produce gap between the two-piston of this structure, cause occurring impacting and abnormal sound, Returnning spring is external also easily causes liquid cylinder piston eccentric wear and leakage of oil, finally has influence on comfort and the reliability of clutch booster.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of comfort and all excellent clutch boosters of reliability.
For solving the problems of the technologies described above, the clutch booster the utility model proposes comprises the booster housing of push rod and both ends open, be provided with liquid cylinder piston in described booster housing, one end of described push rod and described liquid cylinder piston is connected, described liquid cylinder piston is divided into oil hydraulic cylinder and pneumatic cylinder by the inner chamber of described booster housing, be provided with cylinder piston and Returnning spring in described pneumatic cylinder, described pneumatic cylinder arranged outside has the side cylinder with relaying piston, described liquid cylinder piston is fixedly connected with described cylinder piston, and described Returnning spring is around described liquid cylinder piston.
Preferably, described liquid cylinder piston and described cylinder piston are threaded.
Preferably, be provided with the power take-off mouth on described side cylinder.
The clutch booster that the utility model provides, by liquid cylinder piston and cylinder piston are fixedly connected to form to one-piece piston, has guaranteed in working procedure not exist between two-piston gap, has eliminated impact and abnormal sound; Returnning spring has guaranteed piston not eccentric wear and leakage of oil around liquid cylinder piston.
Further, liquid cylinder piston and cylinder piston are threaded connection the processing of being convenient to one-piece piston.
Further, the power take-off mouth arranged on the side cylinder can conveniently be connected with power take-off.
The accompanying drawing explanation
Figure 1 shows that the utility model clutch booster embodiment's structural representation.
In figure, indicate as follows:
Booster housing-1, push rod-2, oil hydraulic cylinder-3, pneumatic cylinder-4, liquid cylinder piston-5, cylinder piston-6, liquid entering hole-7, Returnning spring-8, side cylinder-9, relaying piston-10, suction port-11, relief opening-12, compressed air channel-13, power take-off mouth-14.
Embodiment
For above-mentioned purpose, the feature and advantage that make model utility can become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
A lot of details have been set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can be in the situation that do similar popularization without prejudice to the utility model intension, so the utility model is not subject to the restriction of following public specific embodiment.
As shown in Figure 1, booster housing 1 both ends open, an end is liquid entering hole 7, the other end opening is supplied with push rod 2 and is connected with liquid cylinder piston 5; Liquid cylinder piston 5 is divided into oil hydraulic cylinder 3 and 4 two parts of pneumatic cylinder by the inner chamber of booster housing 1, is provided with cylinder piston 6 in pneumatic cylinder 4, and liquid cylinder piston 5 is fixedly connected with to form one-piece piston with cylinder piston 6; Returnning spring 8 is positioned at pneumatic cylinder 4, and around liquid cylinder piston 5; Pneumatic cylinder 4 arranged outside have side cylinder 9, are provided with again relaying piston 10 in side cylinder 9.Those skilled in the art easily expect, above-mentioned be fixedly connected with can be threaded connection, sell connect or the realization such as key connection, produce for convenient, preferably can adopt and be threaded, more preferably adopt the liquid cylinder piston outside thread to be connected with the cylinder piston screw-internal thread fit.In addition, oil hydraulic cylinder 3 and pneumatic cylinder 4 can adopt integrated method preparation.
The clutch booster that the utility model provides also can comprise power take-off mouth 14, and it is positioned at the outside of side cylinder 9, and is communicated with the cavity of relaying piston 10 peripheries.
In real work, the liquid entering hole 7 of clutch booster is connected with clutch master cylinder, suction port 11 is connected with compressed air plant, when stepping on clutch, fluid enters oil hydraulic cylinder 3 from liquid entering hole 7, act on liquid cylinder piston 5, promotion liquid cylinder piston 5 and the cylinder piston 6 be fixedly connected with liquid cylinder piston 5 move to push rod 2 directions, and push rod 2 promotes clutches; Simultaneously, fluid approaching side cylinder 9, act on relaying piston 10, promote relaying piston 10, sealing relief opening 12, pressurized air enters and enters pneumatic cylinder 4 promotion cylinder pistons 6 by compressed air channel 13 from suction port 11 and moves, and for push rod 2 promotes clutches, provides power-assisted; Booster mouth 14 can be connected with booster, provides pressurized air after the cavity of relaying piston 10 peripheries enters compressed air channel 13, then enters pneumatic cylinder 4, further for push rod 2 promotes clutch, provides power-assisted.After loosen the clutch, hydraulic piston 5 and cylinder piston 6 reset, and relaying piston 10 resets, and compressed air channel 13 is communicated with relief opening 12, and pressurized air is discharged.
Although the utility model is described in conjunction with above embodiment, but the utility model is not defined to above-described embodiment, and only be subject to the restriction of claims, those of ordinary skills can easily modify to it and change, but do not leave essence design of the present utility model and scope.
