Alternatively, described sensor setting has the fitting surface of fitting with the outer surface of cylinder body.
Alternatively, the fitting surface of described sensor is arch structure.
Alternatively, the fitting surface of described sensor is plane structure, and the outer surface correspondence of described cylinder body is provided with supporting surface.
Alternatively, several first joints described form the first outer shroud, and several second joints described form the second outer shroud, and described sensor is between the first outer shroud and the second outer shroud.
Alternatively, described sensor is connected with the first joint and the second joint by inserting mode.
Alternatively, the two ends of described sensor are provided with opening, and described opening is corresponding with described first joint and the second joint and connected by plug-in unit.
Alternatively, one end of described sensor is provided with opening, and the other end is provided with male member, and described male member is corresponding with the first joint to be connected, and described opening is corresponding with the second joint and connected by plug-in unit.
The present invention also provides a kind of clutch release system, comprises above-mentioned arbitrary piston cylinder.
Compared with prior art, technological scheme of the present invention has the following advantages:
The sensor of piston cylinder can do shift in position along cylinder body circumferential direction, is conveniently arranged in different platform by piston cylinder.
Accompanying drawing explanation
Fig. 1 is the stereogram of the piston cylinder of the specific embodiment of the invention;
Fig. 2 is the three-dimensional sensor figure of the specific embodiment of the invention.
Embodiment
Piston cylinder of the present invention can change the mounting point of sensor along cylinder body circumferential direction for different application platforms.Piston cylinder can be oil hydraulic cylinder or pneumatic cylinder, wherein, oil hydraulic cylinder can be clutch master cylinder, clutch from cylinder or brake master cylinder, for ease of setting forth technological scheme of the present invention, will set forth for clutch master cylinder below.
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
With reference to Fig. 1, piston cylinder 20 comprises: cylinder body 21 and sensor 22, and cylinder body 21 and sensor 22 are for removably connecting.Piston cylinder 20 also comprises: at cylinder body 21 outer surface cylinder body 21 circumference is provided with several the first joint 231 and the second joints 232, described first joint 231 is spaced from each other vertically with the second joint 232 and relative one by one, sensor 22 is circumferentially selectively installed on wherein between any one first joint 231 and the second joint 232, realizes sensor 22 and changes at cylinder body 21 circumferential position.Like this, the mounting point of sensor 22 is changed along cylinder body 21 circumference, conveniently piston cylinder 20 of the present invention can be arranged on different platform, avoid the position of sensor 22 to form interference to the installation of piston cylinder 20, achieve piston cylinder 20 of the present invention application on multiple platforms.
With reference to Fig. 1, several first joints 231 circumferentially form the first outer shroud 241, and several first joints 231 and the first outer shroud 241 are structure as a whole; Several second joints 232 circumferentially form the second outer shroud 242, several second joints 232 and the second outer shroud 242 are structure as a whole, sensor 22 is between the first outer shroud 241 and the second outer shroud 242, and sensor 22 is connected with the first joint 231, second joint 232 by inserting mode.
Particularly, with reference to Fig. 2, one end of sensor 22 is provided with opening 26, and the other end is provided with male member 25.Accordingly, the first joint 231 and the second joint 232 are provided with axially relative mounting hole, and male member 25 stretches into the mounting hole of the first joint 231 and achieves a fixed connection, and opening 26 is fixedly connected with by plug-in unit 27 with the mounting hole of the second joint 232.
In another embodiment, the two ends of sensor 22 are provided with opening, and described opening is corresponding with the mounting hole of the first joint 231 and the mounting hole of the second joint 232 and connected by plug-in unit.Can also be, first joint 231 is provided with the male member towards the second joint 232, second joint 232 is provided with axially extended mounting hole, the male member of the first joint 231 stretches into the one end open of sensor 22, and the other end opening of sensor 22 is connected by plug-in unit with the mounting hole of the second joint 232.
