Description
Technical Field
The utility model belongs to the technical field of clutch slave cylinders, and particularly relates to a shell blank structure of a clutch slave cylinder.
Background
The clutch slave cylinder is an important component of an automobile clutch control mechanism, and the method for reducing the clutch pedal force is the most common method for driving the clutch slave cylinder to separate the clutch shifting fork by assisting a vehicle-mounted pressurized air source on a manual gearbox of a commercial vehicle. The clutch slave cylinder converts the fluid displacement of the master cylinder into a mechanical movement of the clutch lever.
As shown in FIG. 5, in the existing domestic slave cylinder of the clutch, the left side is a master cylinder piston rod cavity D1, the right side is a master cylinder D2, brake fluid from the master cylinder A enters a fluid inlet, on one hand, the metal piston rod D3 is pushed to drive the whole piston disc D4 to move towards the right side, so that a metal push rod D5 extends out, and a shifting fork of the clutch is pushed to realize the separation of the clutch, on the other hand, the brake fluid enters a cavity of an air inlet valve D6 to open an air inlet valve port, so that compressed air enters a master cylinder D2, a boosting piston disc D4 moves towards the right side, and the boosting metal push rod D5 extends out to separate the clutch.
When brake fluid is injected, air in the brake fluid needs to be discharged, so that an exhaust port needs to be arranged at a high point, clutch slave cylinders may be required to be installed in two different installation postures in different vehicles (a rotation angle which takes a central line in the front-back direction of the clutch slave cylinders as a rotation center is formed between the two postures), and thus two sets of grinding tools are required to manufacture a shell blank, so that the high point position which meets the requirement of arranging the exhaust port can be found on the two shell blanks, the development period is longer, and the cost is higher.
SUMMERY OF THE UTILITY MODEL
Based on this, to above-mentioned technical problem, provide a clutch wheel cylinder casing blank structure.
In order to solve the technical problems, the utility model adopts the following technical scheme:
a shell blank structure of a clutch slave cylinder comprises a liquid inlet, a gas inlet valve cavity and a master cylinder piston rod cavity which are formed at the rear part of a shell blank body, wherein the liquid inlet is divided into two paths to be communicated with the gas inlet valve cavity and the master cylinder piston rod cavity.
In the blank structure, the air inlet valve cavity which is higher than the liquid inlet and the main cylinder piston rod cavity is designed when the shell blank body is used in the first installation posture, and the main cylinder piston rod cavity is higher than the liquid inlet and the air inlet valve cavity when the shell blank body is used in the second installation posture, so that the blank structure can be made of a set of grinding tool, the high point position of the air outlet can be found in both postures, the development cycle is short, and the investment cost of the grinding tool is saved.

Detailed Description
As shown in fig. 1 and 2, a blank structure of a casing of a clutch cylinder includes a liquid inlet 120, an air inlet valve cavity and a master cylinder piston rod cavity formed at the rear part of a casing blank body 110.
The liquid inlet 120 is divided into two paths to be communicated with the air inlet valve cavity and the piston rod cavity of the main cylinder.
As shown in FIGS. 1-4, the interior of the section A is the intake valve cavity, and the interior of the section B is the master cylinder piston rod cavity.
The air inlet valve cavity is higher than the liquid inlet 120 and the main air cylinder piston rod cavity when the shell blank body 110 is used in the first installation posture, see fig. 3, and the main air cylinder piston rod cavity is higher than the liquid inlet 120 and the air inlet valve cavity when the shell blank body 110 is used in the second installation posture, see fig. 4, a rotation angle with a central line in the front-back direction of the shell blank body 110 as a rotation center is formed between the first installation posture and the second installation posture.
Preferably, the rear portion of the housing blank body 110 forms a first support portion 130 at the upper half portion of the rear portion when the housing blank body 110 is used in the first mounting posture and a second support portion 140 at the upper half portion of the rear portion when the housing blank body 110 is used in the second mounting posture. The first supporting portion 130 and the second supporting portion 140 are used for penetrating a wear indicator along a direction parallel to the front-rear direction central line, one end of the wear indicator penetrates into the shell of the clutch cylinder and can move together with the internal piston, the other end of the wear indicator is exposed out of the shell, and the wear degree of the clutch friction plate can be judged by observing the exposed length of the end.
In the present embodiment, the first support part 130 is located on the left side of the rear part when the case blank body 110 is used in the first mounting posture, and the second support part 130 is located on the right side of the rear part when the case blank body 110 is used in the second mounting posture.
The above-mentioned rotation angle is 90 degrees.
The liquid inlet 110 is parallel to the front-rear direction center line, the air inlet valve cavity is obliquely arranged and gradually gets away from the front-rear direction center line from back to front, and the piston rod cavity of the main cylinder is parallel to the front-rear direction center line.
As shown in fig. 3, when the case blank body 110 is used in the first mounting posture, the first exhaust port 111 on the upper side is provided on the intake valve chamber, and the first mounting hole 131 for mounting the wear indicator is provided on the first support part 130.
As shown in fig. 4, when the case blank body 110 is used in the second mounting posture, the second exhaust port 112 on the rear side is provided in the master cylinder rod chamber, and the second mounting hole 141 for mounting the wear indicator is provided in the second support portion 140.
However, those skilled in the art should realize that the above embodiments are illustrative only and not limiting to the present invention, and that changes and modifications to the above described embodiments are intended to fall within the scope of the appended claims, provided they fall within the true spirit of the present invention.
