Description of drawings
Fig. 1 is the cross-sectional schematic of the internal structure of magnetic pressure type brake master cylinder of the present invention.
Embodiment
Magnetic pressure type brake master cylinder of the present invention mainly comprises cylinder body 1, the moving part of magnetic, piston pair, oil input channel 7, oil road 8, return spring 6.The moving part of magnetic comprises that elastic packing insulator 2, magnetic field body, magnetic field body comprise fixed magnetic field body 3 and moving field body 4; Fixed magnetic field body 3 and moving field body 4 are arranged in elastic packing insulator 2, and moving field body 4 can move in cylinder body, the magnetic pole of fixed magnetic field body 3 and moving field body 4 be two N utmost points or the S utmost point over against and install; Fixed magnetic field body 3 is electromagnet or permanent magnet, and moving field body 4 is electromagnet or permanent magnet.Front end at cylinder body is equipped with the moving part of magnetic, and piston 9, leather cup 5 and return spring 6 are installed afterwards, and oil input channel 7 and oil road 8 are on cylinder body.The circuit of the moving part of magnetic is connected with current controller, and current controller is connected circuit and is connected with the gear rotational speed instrument with speed of a motor vehicle scanner, and the current controller connection is connected or is arranged on the below of brake petal with brake petal.
In order to improve insulation effect and the promotion of the moving part of magnetic, the material of the elastic packing insulator 2 of the moving part of magnetic can be done by the resilient rubber of apparatus, also can make of resilient silica gel or polyurethane.In order to make the minimizing discrete, the moving field body 4 of the back of the moving part of magnetic can be the moving field body, perhaps rear portion and the piston of moving field body 4 is made an integral body.Light for the operation that makes brake master cylinder, in the working procedure of magnetic pressure type brake master cylinder, mechanical push rod or the push rod of the moving Partial Replacement of employing magnetic outside promote brake master cylinder.In order to make brake master cylinder locking when when work can prevent wheel in emergency braking, the size of the magnetic force of the moving part of magnetic can coordinate by current controller to adjust the size of electrical current to be controlled with speed of a motor vehicle scanner and gear rotational speed instrument, the wheel anti-lock function when having played emergency braking.In order to make each wheel cylinder when working, enough working pressures be arranged, the magnetic pressure type brake master cylinder is when coordinating with wheel cylinder, and a car can only fill a magnetic pressure type brake master cylinder, and the magnetic pressure type brake master cylinder of two or two above quantity also can be installed; Be namely: a magnetic pressure type brake master cylinder can connect a wheel cylinder or a plurality of wheel cylinder, and perhaps a magnetic pressure type brake master cylinder connects the wheel cylinder braking the wheel cylinder of bridge location or connect an automobile.
