Abstract
The utility model relates to a brake master cylinder capable of monitoring position motion of a brake pedal and belongs to the field of production of automobile brakes. A first piston and a second piston are respectively in sleeved connection with the inside of a master cylinder body, a brake lamp sensor is fixedly connected with the master cylinder body, and a distance between the center of the brake lamp sensor and the end face of a master cylinder body flange is S1. The front end of the first piston is provided with a stepped thin wall, the edge of the stepped thin wall is provided with a piston flaring, a magnet is fixedly connected with the first piston through the piston flaring, a distance between the center of the brake lamp sensor and the center of the magnet is S2, and a retainer ring is respectively and fixedly connected with two ends of the magnet. The brake master cylinder has the advantages of being novel in structure and capable of effectively monitoring the position motion of the brake pedal of an automobile, enabling a driver to master the braking situation well, integrating with a monitoring cylinder body inner piston position detecting device and being especially suitable for a motor vehicle control system provided with a running power adjusting device.
Description
Technical field
The utility model belongs to the car brake production field.
Background technology
Master brake cylinder is the critical component in the brake system of car, its Main Function is the effect by treadle effort, after vacuum booster amplifies, act on the brake master cylinder piston, it is travelled forward, and then at master brake cylinder pressure chamber generation hydraulic pressure, again by the brake system delivery hydraulic pressure of master brake cylinder oil outlet to car load, thus the brake function of realization automobile.
There is not warning piece in the early stage master cylinder, their shortcoming is: if occurred fault by pedal to certain connecting link of master cylinder, cause the piston in the master cylinder not produce displacement, namely in master cylinder, do not set up hydraulic pressure, automobile does not just produce brake action yet, cause brake failure, will produce very serious consequence like this.And in this situation master cylinder in early days and fail to provide warning, so can not in time find, also just can not take measures in time.
Summary of the invention
But the utility model provides the master brake cylinder of a kind of monitors brake pedal position and motion, does not produce displacement when causing braking failure because some faults make the master cylinder inner carrier at present to solve, and can not reach the problem of alarm.
The technical solution of the utility model is: first piston and the second piston are socketed with Master cylinder body is inner respectively, brake lamp sensor is captiveed joint with Master cylinder body, distance between brake lamp sensor center and the Master cylinder body end face of flange is S1, the front end of first piston has step thin-wall, there is the piston enlarging at the step thin-wall edge, magnet is captiveed joint with first piston by the piston enlarging, and the distance of brake lamp sensor center and magnetic blow out centre is S2, and back-up ring is captiveed joint with the magnet two ends respectively.
The utility model has the advantage of: novel structure, 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.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that enlarged drawing cuts open in the office that the utility model magnet is connected with first piston;
Fig. 3 is the structural representation of the utility model magnet;
Fig. 4 is the structural representation of the utility model first piston.
The specific embodiment
When back-up ring plays a protective role to magnet, also can play the effect of amassing wealth by heavy taxation to the magnetic field that magnet sends.The profile of magnet designs for annular arrangement, and brake lamp sensor can be arranged at cylinder body radial circumference any direction.The fixed form of magnet on piston adopted the piston enlarging to fix.The step thin-wall of first piston is convenient to the enlarging phase magnet.
Described magnet is as signal generator, and it is assemblied on the master cylinder first piston, can be the induction direction of brake lamp sensor along the axial location of master cylinder, sends field signal.And brake lamp sensor is fixed on the Master cylinder body, and is connected with electronic control unit.When the piston occurrence positions moved, magnet was also thereupon mobile, namely can accurately trigger brake lamp sensor, and make feedback by electronic control unit, realizes the monitoring to piston position.Thereby also realized the monitoring to brake pedal position.
Claims (1)
1. but the master brake cylinder of a monitors brake pedal position and motion, it is characterized in that: first piston and the second piston are socketed with Master cylinder body is inner respectively, brake lamp sensor is captiveed joint with Master cylinder body, distance between brake lamp sensor center and the Master cylinder body end face of flange is S1, the front end of first piston has step thin-wall, there is the piston enlarging at the step thin-wall edge, magnet is captiveed joint with first piston by the piston enlarging, the distance of brake lamp sensor center and magnetic blow out centre is S2, and back-up ring is captiveed joint with the magnet two ends respectively.
