The present invention, the piston is inserted into the cylinder in the longitudinal direction is installed to be installed, the push rod is connected to the piston to transfer the force, and the clutch master cylinder is provided with a sensor on the outside of the cylinder to detect the position of the piston In an embodiment, an annular magnet coupled to an outer diameter of the piston may include a magnet sheet fixedly supporting the magnet at one side of the magnet.
Description
The present invention relates to a clutch master cylinder, and more particularly, to a clutch master cylinder in which an annular magnet is coupled to an outer diameter of a piston, and a magnet supported by a magnet seat is supported by a magnet seat.
In general, a clutch master cylinder of an automobile transmits a load to a push rod of a clutch master cylinder by operation of a clutch pedal. This generates hydraulic pressure in the clutch master cylinder, which is sequentially transmitted from the clutch release cylinder to the release fork and release bearing to manipulate the clutch. The clutch operated in this way transmits the engine's rotational force to the transmission, enables smooth and vibration-free oscillation, temporarily shuts off power flow between the engine and the transmission as needed, and protects the engine and power train from overload. It also plays many roles such as reducing engine and rotational vibrations.
1 is a view showing a clutch master cylinder according to the prior art.
Looking at the conventional clutch master cylinder (10), provided with a cylinder (11) having a hollow cylindrical shape, the
On the other hand, according to the development of the electronic parking brake system (Electronic Parking Brake System), the clutch master cylinder has to transmit the position value of the piston to the ECU (Electronic Control Unit) through the position sensor (Travel Sensor). Because of the operation of the clutch pedal, the auto cruise function, the parking brake function, and the parking brake inter lock function can be implemented depending on the position of the piston in the clutch master cylinder. Because. Therefore, there is a need to know the exact position value of the piston in the cylinder.
The present invention relates to a clutch master cylinder, and more particularly, to a clutch master cylinder to which a magnet is coupled to an outer diameter of a piston, and a magnet seat to which a magnet is fixed by a magnet seat is coupled.
The present invention, the piston is inserted into the cylinder in the longitudinal direction is installed, the push rod is connected to the piston to transmit the force, and the magnet provided with a sensor on the outside of the cylinder to detect the position of the magnet magnet seat In the clutch master cylinder coupled by the, characterized in that it comprises an annular magnet coupled to the outer diameter of the piston, a magnet seat for holding and supporting the magnet on one side of the magnet.
In addition, the present invention is characterized in that it comprises a protrusion formed on one end of the piston, a magnet fitted into the protrusion by the method of forced indentation, a magnet sheet fitted to support the magnet on one side of the magnet.
In addition, the present invention is characterized in that the protrusion is composed of a seating portion to which the magnet is fitted, a fixing groove in which the magnet sheet is positioned to support the magnet, and a locking jaw portion to prevent the magnet sheet from being removed.
In addition, the present invention is characterized in that the magnet sheet has a snap ring shape and a protrusion is formed on a surface facing the magnet, and the magnet is formed with a groove corresponding thereto, so that the protrusion and the groove are engaged with each other.
By the configuration as described above, the present invention can minimize the clearance of the magnet and the magnet sheet used to detect the position of the piston to prevent the minute movement of the magnet to increase the accuracy (accuracy) of the position sensor.
In addition, one end of the piston is formed in the shape of a protrusion, there is an advantage that the magnet magnet to support and fix the ring-shaped magnet and it is coupled to the protrusion to facilitate the coupling of the magnet.
In addition, by combining the magnet to the piston in a simple manner by the magnet sheet can reduce the time required for the production of the product, it is possible to reduce the production cost.
