Abstract
The utility model is related to a kind of plunger-type brake master cylinders monitoring brake pedal, belong to automobile manufacturing field.Second piston component and first piston component are separately mounted in Master cylinder body, brake lamp sensor with Hall switch is fixedly connected with axis vertical direction outside Master cylinder body, second piston components interior has groove structure, plastics clamp spring is mounted in groove structure, magnet is securely fitted in by plastics clamp spring on second piston component, and there are one corresponding positions with the Hall switch in brake lamp sensor for magnet.The utility model has the advantage of：Structure novel, magnet arrangement are fixed on inside second piston, can reduce the length of entire plunger typed master cylinder, can promote the safety of driver；Magnet arrangement is fixed and assembly method is simple, and detachably, the magnet fixed form of conventional structure is mostly riveted structure, non-dismountable；Magnet arrangement has the function that positioning by a plastics clamp spring, can mitigate the weight of entire brake master cylinder assy.
Description
Technical field
The utility model belongs to automobile manufacturing field, refers in particular to a kind of master cylinder of brake system of car.
Background technology
Master cylinder is the critical component in brake system of car, its main function is the effect by pedal force, warp
It after vacuum booster amplification, acts on brake master cylinder piston, it is made to travel forward, and then liquid is generated in master cylinder pressure chamber
Pressure, then hydraulic pressure is conveyed to the braking system of vehicle by master cylinder oil outlet, to realize the brake function of automobile.With prison
The master cylinder for controlling brake pedal function, needs magnet arrangement being fixed on cylinder interior, and as piston moves together, when
Magnet arrangement converts magnetic signal to telecommunications with the brake lamp sensor induction being fixed on outside cylinder body when moving to certain position
Number, control the switch of Brake lamp.Master cylinder with monitoring brake pedal function, the positioning method of magnet arrangement is mostly riveting
It connects, non-dismountable, the parts of phase magnet structure are numerous, and weight is big, and assembly technology is complicated, if event occurs in some parts
Barrier, when braking, brake lamp sensor can not incude, and lose the warning function to rear car, and considerable risk is brought to driver, this
Sample just will produce very serious consequence.
Invention content
The utility model provides a kind of plunger-type brake master cylinder monitoring brake pedal, to solve to step on monitoring braking
The master cylinder parts of plate function are more, and weight is big, and assembly is complicated, and magnet is riveting, non-dismountable, when failure, braking
The problem of lamp sensor can not incude, considerable risk is brought to driver.
The technical solution of the utility model is：Second piston component and first piston component are separately mounted in Master cylinder body,
Brake lamp sensor with Hall switch is fixedly connected with axis vertical direction outside Master cylinder body, and second piston components interior has ditch
Slot structure, plastics clamp spring are mounted in groove structure, and magnet is securely fitted in by plastics clamp spring on second piston component, magnet
There are one corresponding positions with the Hall switch in brake lamp sensor.
The utility model has the advantage of：Structure novel, magnet arrangement are fixed on inside second piston, can reduce entire column
The length of plug master cylinder can promote the safety of driver；Magnet arrangement is fixed and assembly method is simple, detachably, conventional to tie
The magnet fixed form of structure is mostly riveted structure, non-dismountable；Magnet arrangement has the function that positioning by a plastics clamp spring,
The weight of entire brake master cylinder assy can be mitigated.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model magnet being located in second piston component；
Fig. 3 is the structural schematic diagram of groove structure on the utility model second piston component；
Fig. 4 is the structural schematic diagram of the utility model plastics clamp spring；
In figure, Master cylinder body 1, second piston component 2, brake lamp sensor 3, magnet 4, first piston component 5, plastics clamp spring
6, groove structure 7.
Specific implementation mode
Second piston component 2 and first piston component 5 are separately mounted in Master cylinder body 1, and the Brake lamp with Hall switch passes
Sensor 3 is fixedly connected with 1 outside axis vertical direction of Master cylinder body, there is groove structure 7, plastics clamp spring 6 inside second piston component 2
In groove structure 7, magnet 4 is securely fitted in by plastics clamp spring 6 on second piston component 2, and can be with second
The movement campaign of piston element 2, there are one corresponding positions with the Hall switch in brake lamp sensor 3 for magnet 4, should
Relative position makes the magnetic field intensity of the magnet 4 under working condition and the Hall switch of brake lamp sensor 3 match, when magnet is transported
When dynamic, incude with brake lamp sensor 3, magnetic signal can be switched to electric signal, the Hall switch action in brake lamp sensor 3.
