Model utility content
The utility model object overcomes existing above-mentioned existing problems, provides a kind of clutch master cylinder with integrated displacement sensor, by judging that the position of piston movement outputs signal, to control the supply of accelerator drive system in advance, realizes the maximization of fuel-economy.
To achieve these goals, the utility model is by the following technical solutions:
A kind of clutch master cylinder with integrated displacement sensor, comprise cylinder body 1, be provided with piston 2 in cylinder body 1, be provided with fuel supply chamber 9 and pressure chamber 10 in cylinder body 1, in pressure chamber 10, be provided with return spring 6, return spring 6 withstands on one end of piston 2, it is characterized in that the middle part of piston 2 is embedded with magnet 4, the internal chamber wall of cylinder body 1 is provided with guide sleeve 3, is also provided with displacement transducer 8, displacement transducer 8 can sense the position of magnet 4 at cylinder body 1, and displacement transducer 8 is connected with output line 12.The utility model and the clutch master cylinder master cylinder piston of integrated displacement sensor has a magnet, during piston movement, displacement transducer is calculated by the magnetic vector produced, just can obtain the magnet positions preset, this output signal can pass through ECU, the intention of identification driver comparatively early, controls the supply of accelerator drive system in advance, realizes the maximization of fuel-economy.
During concrete enforcement, the two ends of piston 2 are provided with leather cup 5.
During concrete enforcement, the internal chamber wall at the middle part of cylinder body 1 is provided with outwards recessed sealing circular arc 11.
During concrete enforcement, cylinder body 1 is connected with lubricating cup assembly 7.
During work, let slip the clutch, the push rod be attached thereto promotes piston and moves right, when leather cup is by sealing circular arc place, idle stroke is closed under piston action, and master cylinder pressure chamber and fuel supply chamber are isolated, the pressure of pressure chamber starts to rise, now, high pressure oil is discharged from oil outlet, is outputted to the oil pocket of clutch booster by oil pipe; In the process that piston moves right, magnet also moves right thereupon, displacement transducer is calculated by the magnetic vector produced, just can obtain the magnet positions preset, this output signal can pass through ECU, the intention of identification driver comparatively early, controls the supply of accelerator drive system in advance, realizes the maximization of fuel-economy; When releasing the clutch pedal, piston is moved to the left initial position fast under the acting in conjunction of return spring and oil pressure, and pressure chamber is communicated with fuel supply chamber, and the pressure in oil line pipe reduces to zero.
The beneficial effects of the utility model are: the utility model has installed displacement transducer, calculated by the magnetic vector produced, just can obtain the magnet positions preset, this output signal can pass through ECU, the intention of identification driver comparatively early, control the supply of accelerator drive system in advance, realize the maximization of fuel-economy, be highly suitable for the heavy truck of employing hydraulic operation gas booster type clutch system, large and medium bus and engineering machinery etc.
