Embodiment
For the purpose, technological scheme and the advantage that make the embodiment of the invention is clearer, below in conjunction with accompanying drawing specific embodiment is described in detail.
Shown in Fig. 1-2, the embodiment of the invention provides a kind of clutch slave cylinder, be arranged between clutch master cylinder and the clutch shifter, actuator as clutch separation, described clutch slave cylinder includes the cylinder body 1 of an end opening, be respectively equipped with oil inlet passage and exhaust passage with its intracavity inter-connection on the described cylinder body 1, the inner chamber of described cylinder body 1 is provided with spring 2, piston 5 and push rod component 6 from inside to outside successively, and described push rod component 6 is adjustable in length formula structure.
Clutch wheel cylinder structure of the present invention is simple, push rod component adopts the length adjustable structure, improved the unfailing performance of clutch slave cylinder, can proofread and correct by the adjusting of push rod component 6 self length, do not needing to change under the prerequisite of the component such as spring in wheel cylinder or the wheel cylinder, solve well because the factors such as the spring conformity is poor cause after the defective and automobile clutch light weight wearing and tearing of wheel cylinder clutch-pedal travel and become the problem such as large, improve clutch system, save cost, and easy to operate, governing speed is fast.
In one embodiment of the present of invention, described push rod component 6 is divided into front push rod 13 and rear push rod 12, adopts nested mode to be connected between described front push rod 13 and the rear push rod 12, can be so that push rod component 6 length adjustment more convenient and quicker.Preferably, the diameter of one end end of described rear push rod 12 close front push rods 13 is greater than the diameter of front push rod 13, and have an axially extended interior threaded hole, described front push rod 13 is provided with the outside thread that is used near an end end of rear push rod 12, the front and back push rod adopts the nested mode of internal and external threads to connect, this mode is so that component processing is more convenient, save cost, and at two push rod connection parts, the diameter of rear push rod 12 has improved again the firm performance of installing between two push rods greatly greater than front push rod 13 diameters.Described front push rod 13 is provided with an externally threaded end and also is provided with locking nut 14, in push rod component 6 length adjustment when being fit to the position, can be by locking nut so that between the push rod of front and back the position immobilize, simple in structure, easy to operate.
Described oil inlet passage and exhaust passage all are positioned at described cylinder body 1 not on the sidewall of opening one end.Be provided with fittings body 10 in the described oil inlet passage, the rubber that described oil inlet passage ingress is provided with for sealing stops up 11; Be provided with exhaust nozzle 8 in the described exhaust passage, be stamped exhaust nozzle lid 9 on the described exhaust nozzle 8.Form the annular groove at twice interval on the sidewall of described piston 5, be respectively arranged with the front leather cup 4 and the rear leather cup 5 that consist of sealing with inboard wall of cylinder block in the annular groove.Described cylinder body 1 opening end is installed with sidewall and is undulatory dust-proof cover 7.
In one embodiment of the present of invention, the adjustable in length mode of described push rod component 6 can be various ways, for example can the internal and external threads fit system, and also can adopt the modes such as hydraulic jack contraction to realize length adjustment.Equally, the mode that the front and back push rod is nested cooperates except adopting internal and external threads, can also adopt the mode that is slidingly connected, and certainly, the means of fixation of front and back push rod can be multiple, as long as can play the purpose that prevents that the front and back push rod from sliding mutually.
The concrete Principles of Regulation of the present invention are as follows:
1, proofread and correct for clutch slave cylinder push rod initial position:
As shown in Figure 3, the conformity of existing clutch slave cylinder spring is relatively poor, the initial position size of push rod, when namely as shown in fig. 1 spring state is free push rod component 6 heads and mounting hole be difficult to guarantee apart from M, make the clutch slave cylinder off-dimension.And push rod component 6 length of the present invention are adjustable, and the length of push rod 12 guarantees the accurate of M size after screwing in by push rod 13 before adjusting in the push rod component 6, to improve the up-to-standard rate of clutch slave cylinder.
2, after clutch light weight wearing and tearing to the compensation of clutch-pedal travel:
As shown in Figure 4, clutch separates this process of end from beginning to be separated in separation process, and the displacement amount of clutch slave cylinder push rod component 6 is exactly the effect stroke of wheel cylinder, and namely the push rod initial position shown in the A of Fig. 4 is to the distance of push rod final position.Increase along with Vehicle-Miles of Travel, clutch can wear and tear gradually but can also continue and use, wear extent is such as the B among Fig. 5, that the initial position of push rod before the wearing and tearing shown in the figure is to the distance between the initial position of the rear push rod of wearing and tearing, therefore will cause the stroke of clutch slave cylinder to increase the B size, be that final stroke is A+B, the stroke of clutch pedal also can increase thereupon, affects the operability of whole clutch system.
But in the present invention, can compensate by regulating the length that lengthens push rod component 6 wearing and tearing of clutch, the B size that is worn before namely increasing by one accordingly, stroke to clutch pedal compensates, guarantee range or the A size of push rod, make the total kilometres of clutch pedal remain constant, thereby guaranteed the operating characteristics of clutch system.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
