Abstract
The utility model relates to a clutch working cylinder assembly with a function of abnormal sound prevention. The clutch working cylinder assembly comprises a cylinder body, an exhaust bolt, a dust cover, a piston assembly and a push rod; the dust cover is fixed in a groove in the tail end of the cylinder body and further fixed in a groove in the top end of the push rod; the exhaust bolt is fixed onto the cylinder body; the piston assembly is arranged in the cylinder body and comprises a pretension spring, a piston body and a leather cup; the push rod penetrates through the leather cup to be connected with the piston body; the pretension spring is respectively connected with the cylinder body and the piston body; the clutch working cylinder assembly further comprises an anti-attrition noise-reduction cushion cup. Owing to the anti-attrition noise-reduction cushion cup additionally arranged between the push rod and a shifting fork, abrasion between the push rod and the shifting fork can be alleviated while abnormal sound caused by the abrasion can be reduced under the action of elasticity of the anti-attrition noise-reduction cushion cup.
Description
Technical field
The utility model belongs to automobile clutch system technical field, is specifically related to a kind of clutch clutch release slave cylinder assembly of anti-abnormal sound.
Background technique
Clutch clutch release slave cylinder assembly be in clutch system for transmitting and reduce the device of the clutch separation power on clutch pedal, generally comprise the component such as cylinder body, piston, push rod, dust-proof cover and bleeder screw.Clutch pedal Separating force is that driver steps on the required power of clutch pedal, and this power is for the impacting force between cut-off clutch platen and driven disc, thus the transmission of power between cut-out motor and speed changer.Shift fork is for clutch clutch release slave cylinder power being passed to the mechanical part of clutch, due to stressed larger, generally all adopt metal casting or is stamped to form.
On present market there is the hidden danger of abnormal sound in the conventional total Chengdu of clutch clutch release slave cylinder, is because clutch clutch release slave cylinder all adopts metal pushrod directly to contact with metal shift fork at present.Although scribble lubricating grease herein, lubricating grease of long duration can be because the factors such as the extruding between push rod and shift fork, temperature cause lubricating grease fewer and feweri, and the mechanical wear between push rod and shift fork will produce abnormal sound, bring puzzlement to driver and passenger.Therefore, be necessary to design a kind of clutch clutch release slave cylinder assembly of anti-abnormal sound.
Model utility content
The purpose of this utility model is by optimizing clutch slave cylinder push rod and shift fork contact structures, thoroughly solving abnormal sound hidden danger.
The utility model is achieved through the following technical solutions:
A clutch clutch release slave cylinder assembly for anti-abnormal sound, comprises cylinder body, bleeder screw, dust-proof cover, piston assembly, push rod; Described dust-proof cover is separately fixed in cylinder body end groove and in the groove of push rod top; Described bleeder screw is fixed on cylinder body; Described piston assembly is arranged in cylinder body; Described piston assembly comprises prefastening force spring, piston only and leather cup; Described push rod is connected with piston only through after leather cup; Described prefastening force spring is connected with piston only with cylinder body respectively; Described clutch clutch release slave cylinder assembly also includes anti-attrition noise reduction washbowl, and the end of described dust-proof cover snaps in anti-attrition noise reduction washbowl; Described anti-attrition noise reduction washbowl ball-and-socket end encases the push rod top that is fixed with dust-proof cover, and an other side snaps in shift fork ball-and-socket simultaneously.
Described anti-attrition noise reduction washbowl is bowl structure.
Between described push rod and shift fork, by prefastening force spring, compress, described dust-proof cover, push rod, anti-attrition noise reduction washbowl and shift fork all compress, without relative movement.
Useful technique effect of the present utility model is:
Anti-attrition noise reduction washbowl of the present utility model plays and reduces the effect of wearing and tearing between push rod and shift fork, can avoid the generation of abnormal sound simultaneously; Dust-proof cover snaps in anti-attrition noise reduction washbowl and realizes the sealing to cylinder body, can effectively prevent that cylinder body from entering dust and other impurities.
Accompanying drawing explanation
Fig. 1 is clutch clutch release slave cylinder assembly axonometric drawing;
Fig. 2 is clutch clutch release slave cylinder assembly plan view;
Fig. 3 is the A-A sectional view of Fig. 2.
Specific embodiment
By specific embodiment, describe the technical solution of the utility model below, following instance is only exemplary, only can be used for explaining and explanation the technical solution of the utility model, and can not to be interpreted as is the restriction to technical solutions of the utility model.
As shown in Figure 1 to Figure 3, the present embodiment relates to clutch clutch release slave cylinder assembly, comprise cylinder body 1, bleeder screw 2 is installed on cylinder body 1, dust-proof cover 3, piston assembly 6, push rod 7, anti-attrition noise reduction washbowl 8, and wherein piston assembly 6 comprises prefastening force spring 6.1, piston only 6.2 and leather cup 6.3.Cylinder body 1 is fixed on car body by fixed hole (1.2 and 1.3), and anti-attrition noise reduction washbowl 8 is bowl structure.
As shown in Figure 3, dust-proof cover 3 is separately fixed in cylinder body end groove and push rod top groove, dust-proof cover end snaps in anti-attrition noise reduction washbowl 6 simultaneously.The ball-and-socket end of anti-attrition noise reduction washbowl 6 encases push rod 7 tops that are fixed with dust-proof cover, and an other side snaps in shift fork 7 ball-and-sockets simultaneously.
When brake fluid flows into cylinder interior filler opening side through clutch clutch release slave cylinder filler opening 1.1, then promote piston assembly 6, finally by piston assembly 6, promote push rod 7, push rod 7 promotes shift fork 4, by shift fork 4, promotes push rod 5 actions.
On car load, between push rod 7 and shift fork 4, one compresses straight through prefastening force spring 6.1, thus dust-proof cover 3, push rod 7, anti-attrition noise reduction washbowl 8 and shift fork 4 all compress, without relative movement.
The utility model is between push rod and shift fork, to increase anti-attrition noise reduction washbowl; Elasticity by anti-attrition noise reduction washbowl reduces wearing and tearing and the abnormal sound between push rod and shift fork; Dust-proof cover, except all fluted fixing with cylinder body end, push rod top, also snaps in addition in anti-attrition noise reduction washbowl and realizes the sealing to cylinder body simultaneously, can effectively prevent that cylinder body from entering dust and other impurities;
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that not departing from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiments, scope of the present utility model is by claims and be equal to and limit.
