Abstract
The invention relates to a brake master cylinder capable of monitoring a location and movement of a brake pedal and belongs to the field of automobile brake. The brake master cylinder comprises a master cylinder body, a first piston and a second piston in the master cylinder body, as well as components of the first piston and the second piston, wherein an external axis of the master cylinder body is fixedly connected with a brake lamp sensor manufactured by a hall switch; a rubber ring of an internal plastic magnet is fixedly assembled in an annular groove in an internal wall of the master cylinder body; the magnet in the rubber ring has a relative position to the hall switch in the brake lamp sensor; and the relative position allows the magnetic field intensity of the magnet in the rubber ring in a working state to be matched with the hall switch of the brake lamp sensor. The cylinder has the advantages that the cylinder is novel, simple and practical in structure, integrates a detection device for monitoring the positions of the pistons in the cylinder body and is particularly applicable to a motor vehicle control system with a running power adjustment device.
Description
Technical field
The invention belongs to automobile brake field, 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, it is travelled forward, and then produce hydraulic pressure at master brake cylinder pressure chamber, then pass through master brake cylinder oil outlet to the brake system delivery hydraulic pressure of car load, thus realize the brake function of automobile.
In drag process, for guaranteeing that the intention of travelling of chaufeur perception the place ahead, rear chaufeur is slowed down in time, avoid vehicle rear-end collision accident to occur, stop lamp switch is installed at pedal support position, and the associated mechanisms compression brake light switch that connects pedal when braking is realized the function of sending speed-slackening signal.But this structure is more complicated, exist signal to send the phenomenon of hysteresis.
Simultaneously, in early stage master cylinder, there is no integrated brake lamp sensor, their shortcoming is: if there is fault by pedal to certain connecting link of master cylinder, cause the piston in master cylinder not produce displacement, namely in master cylinder, do not set up hydraulic pressure, automobile does not just produce brake action yet, causes brake failure, will produce very serious consequence like this.And also could not provide warning in this situation master cylinder in early days, and so can not find in time, also just can not take measures in time, although the master cylinder of the band brake lamp sensor occurring successively afterwards, structure is all more complicated.
Summary of the invention
The invention provides a kind of can monitors brake pedal position and the master brake cylinder of motion, with solve exist at present because some faults make master cylinder inner carrier not produce displacement, cause braking failure, but can not and the problem of alarm.
The technical scheme that the present invention takes is: comprise that Master cylinder body is with its inner first piston and by first piston spring, stop screw one, the assembly that positioning seat forms, the second piston and by stop screw two, spring limit base, the assembly that the second piston spring forms, and primary cup one, secontary cup one, primary cup two, secontary cup two, steel ball, the outside axis vertical direction of Master cylinder body is fixedly connected with a brake lamp sensor of being made by Hall switch, inside is moulded the rubber ring that closes magnet and is fixedly assemblied in Master cylinder body inwall circular groove, magnet and the Hall switch in brake lamp sensor in rubber ring have a relative position, this relative position matches the magnetic-field intensity of the magnet in rubber ring and the Hall switch of brake lamp sensor under mode of operation.
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 magnet in rubber ring.
Advantage of the present invention is: novel structure, simple and practical, solved and because some faults make master cylinder inner carrier, do not produced displacement while causing braking failure at present, 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 that is 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.

The specific embodiment
Comprise that Master cylinder body 1 is with its inner first piston 5 and by first piston spring 8, stop screw 1, the assembly that positioning seat 11 forms, the second piston 2 and by stop screw 2 14, spring limit base 16, the assembly that the 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 axis vertical direction of Master cylinder body 1 is fixedly connected with a brake lamp sensor of being made by Hall switch 3, inside is moulded the rubber ring 4 that closes 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 matches the magnetic-field intensity of the magnet in rubber ring 4 19 under mode of operation and the Hall switch of brake lamp sensor 3.
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 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, can along the radial position of Master cylinder body, be the induction direction of brake lamp sensor, sends 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, make positioning seat compressing rubber circle cause the magnet in rubber ring to move radially, can accurately trigger brake lamp sensor, and make feedback by electronic control unit, realize the monitoring to piston position.Thereby also realized the monitoring to brake pedal position.
Positioning seat 11 in first piston 5 is with annular boss 12, when first piston 5 and assembly positioning seat thereof 11 is during by rubber ring 4, annular boss 12 extruding rubber rings 4, make the magnet 19 in rubber ring 4 carry out radial motion, and this section of rubber ring entered in the gap 12 on Master cylinder body ring-type rectangular channel 20.
