Description
Technical field
The utility model relates to the linkage structure of a kind of shift fork and push rod, relates in particular to a kind of linkage structure that is used for the shift fork and the push rod of clutch, specifically is applicable to the vehicle that adopts the shift fork cut-off clutch.
Background technique
At present, clutch is the important component part in the internal combustion car transmissions, and in order to alleviate the working strength of driver when operating, the booster of clutch has obtained using very widely, during utilization, the annexation between clutch shifter and the booster push rod is very important.Referring to Fig. 1, Fig. 1 is the prior art constructions schematic representation, and the linkage structure among the figure comprises shift fork 1 and push rod 2, and shift fork 1 adopts ball to be connected with 2 of push rods, the bulb 21 of push rod 2 directly gos deep in the shift fork ball-and-socket 11 of shift fork 1 lower end, carries out transmission between shift fork ball-and-socket 11 and the bulb 21 and cooperates.Because in the prior art, shift fork 1 and push rod 2 directly cooperate, thereby can aggravate the wearing and tearing of shift fork 1 upper shift fork ball-and-socket 11, especially after shift fork ball-and-socket 11 was damaged, because shift fork ball-and-socket 11 is structure as a whole with shift fork 1, just must change shift fork 1 this moment, and cost is higher.In addition, prior art does not have dust sealing completely in clutch housing 8, and dust-proof cover 4 can only cover sub-fraction, thereby dustproof effect is relatively poor.
The Chinese patent publication number is CN101713439A, the patent of invention that open day is on May 26th, 2010 discloses a kind of multifunctional clutch booster, comprise the power-assisted part, air flue cavity part, targeting part, control section and valve body, described power-assisted partly comprises the power-assisted cylinder body, the power-assisted push rod, boosting piston, tip-lever support and piston rod, described control section comprises air intake valve, drain tap, hydraulic piston, control piston, bilateral single valve and solenoid valve, described air flue cavity partly comprises respiration channel and variable volume chamber, and piston rod is passed through in described variable volume chamber at least, targeting part and hydraulic piston form.Though the piston rod in this invention separates fully with hydraulic piston, and directly or indirectly the negative pressure air cavity is connected with atmospheric air port by respiration channel, thoroughly eliminated the servo-actuated phenomenon of hydraulic piston, the life-span of hydraulic piston and the sensitivity of electric control operation have been improved, but the linkage structure of taking on its push rod still is simple push rod, ball-and-socket to be cooperated, not only the shift fork push rod is easy to wear, can increase user cost, and be unfavorable for the dismounting of push rod, increased operation easier, simultaneously, dust-proof cover also can only cover the position, a little position in the clutch housing, and dustproof effect is relatively poor.
Summary of the invention
The purpose of this utility model be overcome that the shift fork push rod that exists in the prior art is easy to wear, user cost is higher, be difficult for removing, dustproof relatively poor defective and the problem of effect, the linkage structure that provide that a kind of shift fork push rod is not easy to wear, user cost is lower, readily removablely remove, dustproof effect is used for the shift fork and the push rod of clutch preferably.
For realizing above purpose, technical solution of the present utility model is: a kind of linkage structure that is used for the shift fork and the push rod of clutch, comprise shift fork and push rod, and described shift fork is provided with ball-and-socket, one end of push rod is provided with the bulb that matches with ball-and-socket, and the outer cover of the other end is equipped with dust-proof cover; Described shift fork is provided with the ball-and-socket lining coaxial with push rod, and the inside of ball-and-socket lining one end is provided with the ball-and-socket that matches with bulb.
The outside of the described ball-and-socket lining the other end is that interference is connected or snap-in connection with Placement between the shift fork.
The cross section of described ball-and-socket lining is trapezoidal.
One end of described ball-and-socket lining matches with bulb, and the other end is connected with the inner apical pore that is provided with of shift fork, and the other end of apical pore is connected with the outer surface of shift fork.
Described apical pore and push rod, the coaxial setting of ball-and-socket lining.
The outer cover at the position on the described push rod between shift fork, dust-proof cover is equipped with the bulb seal closure, and an end of bulb seal closure is connected with shift fork, and the other end is connected with push rod.
Compared with prior art, the beneficial effects of the utility model are:
1, is used for the shift fork of clutch and the linkage structure shift fork of push rod is provided with the ball-and-socket lining coaxial with push rod because the utility model is a kind of, the inside of ball-and-socket lining one end is provided with the ball-and-socket that matches with bulb, during use, match with bulb by the ball-and-socket that is provided with on the ball-and-socket lining, and unlike prior art, directly match with push rod by shift fork, this design with the alternative shift fork of ball-and-socket lining has reduced the wearing and tearing of shift fork, and the price of ball-and-socket lining is lower, thereby reduces and also just reduced user cost when shift fork is changed frequency.Therefore not only the shift fork push rod is not easy to wear for the utility model, and user cost is lower.
2, match with bulb with an end of the linkage structure ball-and-socket lining of push rod owing to a kind of shift fork that is used for clutch of the utility model, the other end is connected with the inner apical pore that is provided with of shift fork, the other end of apical pore is connected with the outer surface of shift fork, when in using, needing to remove shift fork and ball-and-socket lining, only need put in the apical pore and can eject the ball-and-socket lining with gadgets, very convenient.Therefore the utility model is readily removable removes.
3, be used for the shift fork of clutch and the outer cover of linkage structure at the position between shift fork, dust-proof cover on the push rod of push rod is equipped with the bulb seal closure because the utility model is a kind of, one end of bulb seal closure is connected with shift fork, the other end is connected with push rod, this design makes the interior institute of clutch housing have living space and all is provided with dustproof construction, the linkage structure that can effectively avoid the dust etc. in the clutch housing to enter shift fork and push rod, delay wearing and tearing, increase working life.Therefore dustproof effect of the present utility model is better.
