Abstract
Can the master brake cylinder of monitors brake pedal position and motion, belong to field of automobile brake.Comprise the first piston of Master cylinder body and its inside, the second piston and assembly thereof, the outside axes normal direction of Master cylinder body is fixedly connected with a brake lamp sensor be made up of Hall switch, inside is moulded the rubber ring closing magnet and is fixedly assemblied in Master cylinder body inwall circular groove, magnet in rubber ring and the Hall switch in brake lamp sensor have a relative position, and this relative position makes the magnetic-field intensity of magnet under mode of operation in rubber ring and the Hall switch of brake lamp sensor match.Advantage is: novel structure, simple and practical, and it is a kind of master cylinder being integrated with monitoring cylinder body inner carrier positional detecting device, is specially adapted to have in the motor vehicle control system of driving dynamics control apparatus.
Description
Technical field
The invention belongs to field of automobile brake, refer in particular to a kind of being applied to compared with the master brake cylinder in the brake system of luxury car and micro-car.
Background technology
Master brake cylinder is the critical component in brake system of car, its Main Function is the effect by treadle effort, after vacuum booster amplifies, act on brake master cylinder piston, make it travel forward, and then produce hydraulic pressure at master brake cylinder pressure chamber, then by the brake system delivery hydraulic pressure of master brake cylinder oil outlet to car load, thus realize the brake function of automobile.
In drag process, vehicle collides therewith is avoided to occur for ensureing that the traveling intention of chaufeur perception front, rear chaufeur is slowed down in time, install stop lamp switch at pedal support position, the associated mechanisms compression brake light switch connecting pedal when braking realizes the function sending speed-slackening signal.But this structure is more complicated, there is signal and send delayed phenomenon.
Simultaneously, integrated brake lamp sensor is not had in early stage master cylinder, their shortcoming is: if there is fault by pedal to certain connecting link of master cylinder, the piston in master cylinder is caused not produce displacement, namely in master cylinder, do not set up hydraulic pressure, automobile does not also just produce brake action, causes brake failure, will produce very serious consequence like this.And warning could not be provided in this situation master cylinder in early days, so can not Timeliness coverage, also just can not take measures in time, although the master cylinder of the band brake lamp sensor occurred successively afterwards, structure be all more complicated.
Summary of the invention
The invention provides a kind of can the master brake cylinder of monitors brake pedal position and motion, with solve exist at present make master cylinder inner carrier not produce displacement because of some faults to cause braking failure, but can not and the problem of alarm.
The technical scheme that the present invention takes is: comprise Master cylinder body with the first piston of its inside and by first piston spring, stop screw one, the assembly of positioning seat composition, second piston and by stop screw two, spring retainer seat, the assembly of the second piston spring composition, and primary cup, secontary cup one, primary cup two, secontary cup two, steel ball, the outside axes normal direction of Master cylinder body is fixedly connected with a brake lamp sensor be made up of Hall switch, inside is moulded the rubber ring closing magnet and is fixedly assemblied in Master cylinder body inwall circular groove, magnet in rubber ring and the Hall switch in brake lamp sensor have a relative position, this relative position makes the magnetic-field intensity of magnet under mode of operation in rubber ring and the Hall switch of brake lamp sensor match.
Rubber ring of the present invention, its internal diameter is less than the internal diameter of Master cylinder body.
Positioning seat of the present invention is with annular boss, and this annular boss contacts with rubber ring and the external diameter of this annular boss is greater than the internal diameter of rubber ring.
There is gap in the position of the cooperation that Master cylinder body ring-type rectangular channel of the present invention is corresponding with the magnet in rubber ring.
Advantage of the present invention is: novel structure, simple and practical, solve and make because of some faults at present master cylinder inner carrier not produce displacement when causing braking failure, can not and the problem of alarm, the situation of the position motion of energy actv. monitoring automobile brake pedal, makes chaufeur can better grasp the situation of braking.It is a kind of master cylinder being integrated with monitoring cylinder body inner carrier positional detecting device, is specially adapted to have in the motor vehicle control system of driving dynamics control apparatus.

Detailed description of the invention
Comprise Master cylinder body 1 with the first piston 5 of its inside and by first piston spring 8, stop screw 1, the assembly that positioning seat 11 forms, second piston 2 and by stop screw 2 14, spring retainer seat 16, the assembly that second piston spring 17 forms, and primary cup 1, secontary cup 1, primary cup 2 15, secontary cup 2 13, steel ball 7, the outside axes normal direction of Master cylinder body 1 is fixedly connected with a brake lamp sensor be made up of Hall switch 3, inside is moulded the rubber ring 4 closing magnet 19 and is fixedly assemblied in Master cylinder body 1 inwall circular groove 20, magnet 19 in rubber ring 4 has a relative position with the Hall switch in brake lamp sensor 3, this relative position makes the magnetic-field intensity of magnet 19 under mode of operation in rubber ring 4 and the Hall switch of brake lamp sensor 3 match.
Rubber ring 4 of the present invention, its internal diameter is less than the internal diameter of Master cylinder body 1.
Positioning seat 11 of the present invention is with annular boss 18, and this annular boss 18 contacts with rubber ring 4 and the external diameter of this annular boss 18 is greater than the internal diameter of rubber ring 4.
There is gap 12 in the position of the cooperation that Master cylinder body ring-type rectangular channel 20 of the present invention is corresponding with the magnet 19 in rubber ring 4.
Principle of work is: described with the magnet in the rubber ring of magnet as signal generator, it is assemblied on master cylinder cylinder, along the induction direction of the radial position of Master cylinder body and brake lamp sensor, can send field signal; And brake lamp sensor is fixed on Master cylinder body outer wall, and be connected with electronic control unit, when first piston occurrence positions moves, promote first piston spring and drive the corresponding movement of positioning seat, positioning seat compressing rubber circle is made to cause the magnet in rubber ring to move radially, namely accurately can trigger brake lamp sensor, and make feedback by electronic control unit, realize the monitoring to piston position.Thus the monitoring also achieved brake pedal position.
Positioning seat 11 in first piston 5 is with annular boss 12, when first piston 5 and assembly positioning seat 11 thereof are by rubber ring 4, annular boss 12 extrudes rubber ring 4, makes the magnet 19 in rubber ring 4 carry out radial motion, in the gap 12 that this section of rubber ring is entered on Master cylinder body ring-type rectangular channel 20.
