Abstract
The utility model relates to an automobile clutch booster assembly which comprises a booster cylinder barrel, a push rod arranged in the booster cylinder barrel and a booster cylinder piston head connected with the push rod in a linkage mode. The work end of the push rod extends out of the booster cylinder barrel, the other end, opposite to the end connected with the push rod in the linkage mode, of the booster cylinder piston head is provided with a shell and a piston rod, the shell and the piston rod are connected with the booster cylinder barrel, a compression spring is arranged between the booster cylinder piston head and the inner wall of the booster cylinder barrel, the shell and the booster cylinder barrel are locked through a fastening piece, and a concentric locating mechanism is arranged between the shell and the booster cylinder barrel. The automobile clutch booster assembly is convenient to assemble, and improves assembly efficiency.
Description
Technical field
The utility model relates to a kind of automobile clutch booster assembly.
Background technique
Automobile clutch hydraulic operation gas power assisting device mainly by clutch pedal, oil can, clutch master cylinder, high pressure with low pressure fuel pipe, clutch booster assembly, separate the members such as rocking arm, shift fork and form.Manipulation process is: driver's disengage the clutch, in master cylinder, oil pressure raises, increasing along with pedal shape journey, pressure oil arrives clutch booster assembly Hydraulic Main chamber through high-pressure oil pipe by clutch master cylinder, the promotion relay piston moves down, open air intake valve, pressurized air leads to clutch booster assembly cylinder by suction port, now the clutch booster push rod promotes to separate rocking arm and rotates around declutch shift shaft under the acting in conjunction of oil pressure and air pressure, thereby the promotion release bearing, release bearing promotes clutch diaphragm spring and makes clutch separation.The clutch booster assembly is except providing power-assisted to control system, and also it has follow-up action to the particularity of its structure, guarantees clutch separation structure and clutch pedal synchronization motion.
When the housing in traditional automobile clutch booster assembly is connected with the power-assisted cylinder barrel, need with the outer shape of special tooling location, not only efficiency of assembling is low, and concentricity can not well guarantee.
Summary of the invention
The deficiency existed for prior art, the utility model provides a kind of easy to assembly, automobile clutch booster assembly of improving efficiency of assembling.
For achieving the above object, the utility model provides following technological scheme: a kind of automobile clutch booster assembly, include the power-assisted cylinder barrel, the servo-cylinder piston head of being located at the push rod in the power-assisted cylinder barrel and being connected with push rod, the working end of push rod extends to outside the power-assisted cylinder barrel, the servo-cylinder piston head is provided with respect to the be connected the other end place of an end of push rod housing and the piston rod be connected with the power-assisted cylinder barrel, be provided with Compress Spring between the inwall of servo-cylinder piston head and power-assisted cylinder barrel, it is characterized in that: between described housing and power-assisted cylinder barrel, by fastening piece, lock, and be provided with concentric locating mechanism between housing and power-assisted cylinder barrel.
Wherein, concentric locating mechanism include the location cavity be located on the power-assisted cylinder barrel and housing that on the end face of power-assisted cylinder barrel, arrange with positioning boss location cavity adaptation.
Adopt technique scheme, by between housing and power-assisted cylinder barrel, concentric locating mechanism being set, make housing and power-assisted cylinder barrel in installation process, at first can locate by the concentric locating mechanism for implementing, behind its location, implement locking by fastening piece again, saved the frock of the special-purpose orientation assemble of single station, efficiency of assembling is improved greatly.
The utility model further is set to: Compress Spring is belleville spring.
Adopt technique scheme, elastic compression power is set so better.
Below in conjunction with accompanying drawing, the utility model is further described.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment;
The I section enlarged diagram that Fig. 2 is Fig. 1.
Embodiment
A kind of automobile clutch booster assembly as shown in Figure 1 and Figure 2, the servo-cylinder piston head 3 that includes power-assisted cylinder barrel 1, is located at the push rod 2 in power-assisted cylinder barrel 1 and is connected with push rod 2, the working end 21 of push rod 2 extends to outside power-assisted cylinder barrel 1, servo-cylinder piston head 3 is provided with respect to the be connected the other end place of an end of push rod 2 housing 4 and the piston rod 5 be connected with power-assisted cylinder barrel 1, be provided with Compress Spring 6 between the inwall of servo-cylinder piston head 3 and power-assisted cylinder barrel 1, in order to improve pressure elasticity power, Compress Spring 6 is belleville spring; Lock by fastening piece between housing 4 and power-assisted cylinder barrel 1, and be provided with concentric locating mechanism 7 between housing 4 and power-assisted cylinder barrel 1; Fastening piece is lock bolt.In such scheme, by between housing 4 and power-assisted cylinder barrel 1, concentric locating mechanism 7 being set, make housing 4 and power-assisted cylinder barrel 1 in installation process, at first can implement location by concentric locating mechanism 7, behind its location, implement locking by fastening piece again, saved the frock of the special-purpose orientation assemble of single station, efficiency of assembling is improved greatly.
In the utility model embodiment, concentric locating mechanism 7 include the location cavity 71 be located on power-assisted cylinder barrel 1 and housing 4 that on the end face of power-assisted cylinder barrel 1, arrange with positioning boss 72 location cavity 71 adaptations.It should be noted that, also positioning boss can be located on power-assisted cylinder barrel 1, be located on housing 4 and will locate cavity, is also feasible.
Claims (3)
