Description
Technical field
The utility model relates to the device that is used to prevent brake locking in the automobile brake system, is the constituent elements in the automobile brake system, and it is installed in the automobile brake system to prevent brake locking.
Technical background
Automatically anti-lock braking system (ABS) is a kind of vehicle safety control system with advantage such as anti-skidding, anti-lock, is the improved technique on the conventional brake gear basis, can be divided into two kinds of mechanical type and electronic types.
Mechanical type ABS's is simple in structure, mainly is a mechanical valve, utilizes in the valve body rubber pneumatic bag constantly to loosen, brake what the feedback of brake pressure realized braking, thereby reaches the result of not locking of tire.Electronic type ABS is by component set-ups such as wheel speed sensors, wire harness, computer, ABS Hydraulic Pump, indicator lamps, can wait according to friction force, rotating speed, angle of turn and the body inclination degree of each wheel to send signal to the computer system of vehicle, distribute the braking strength frequency by computer, the output of control engine torsion, each wheel is applied different braking strengths, thereby reach the effect of assignment system power scientifically and rationally, the sideslip of wheel, sideslip, whipping phenomenon when overcoming emergency brake effectively prevent the generation of situations such as vehicle body is out of control.
Though the structure of mechanical type ABS is simple, must mate one for it provides the gas feeder of air pressure, and rubber pneumatic bag is immersed in and easily makes ageing of rubber in the hydraulic oil, thereby makes the service life of mechanical type ABS shorter.
Electronic type ABS complex structure, cost is higher, and because sensor and gear ring are mounted on each wheel, be subjected to the pollution of greasy dirt, dirt easily, particularly the magnet material sticks to its surface, will cause sensor failure or is transferred to the signal error of computing machine and influences the normal operation of ABS system.
The utility model content
The purpose of this utility model provides a kind of automobile anti-lock braking brake gear simple in structure, and it is installed in the automobile brake system, when carrying out drag, can prevent brake locking effectively.
Automobile anti-lock braking brake gear described in the utility model, comprise hydraulic actuating cylinder and vibrating reed, be full of hydraulic oil in the hydraulic actuating cylinder, vibrating reed be fixed in the hydraulic actuating cylinder hydraulic actuating cylinder is separated into separate about two chambeies, in the right chamber of hydraulic actuating cylinder compression spring is installed, its two ends act on the vibrating reed respectively and hydraulic actuating cylinder the inner; On hydraulic actuating cylinder, be equipped with by direct motor drive, can be fixed with cam on the camshaft with respect to the camshaft of hydraulic actuating cylinder rotation, cam is positioned at chamber, a hydraulic actuating cylinder left side, and when cam rotates with camshaft, cam will act on vibrating reed make vibrating reed produce along with the distortion of vibrating reed vertical direction.
This automobile anti-lock braking brake gear is installed in (chamber, a hydraulic actuating cylinder left side connects the automobile hydraulic main pump in the hydraulic circuit of automobile brake system, the right chamber of hydraulic actuating cylinder connects the automobile hydraulic wheel cylinder), make that two chambeies are communicated with the brake system hydraulic circuit about hydraulic actuating cylinder, the electrical motor that will be used for drive cam shaft is connected with the direct supply of automobile, and electric current input foot-operated with brake or that other device comes the control motor.
When the pedal brake that touches on the brake (or the situation of other automatic guidance brake takes place), the electric current input motor makes the rotation of direct motor drive camshaft, cam on the camshaft is also in company with rotation, and a flash the chien shih vibrating reed overcome compression spring power along and the vibrating reed vertical direction produce distortion, under the compression spring effect, reset again afterwards, thus make vibrating reed under the combined action of camshaft and compression spring, produce along with the vibration of vibrating reed vertical direction.
Like this, for the hydraulic oil in the right chamber of hydraulic actuating cylinder, when touching on the brake pedal brake, hydraulic oil in the chamber, a hydraulic actuating cylinder left side will promote vibrating reed, then promote the hydraulic oil in the right chamber of hydraulic actuating cylinder, the piston in the automobile hydraulic wheel cylinder is moved, thereby the brake facing that will connect with this piston promotes, fit with automobile brake butterfly (dish), make automobile brake; And the side to side vibrations of vibrating reed will produce following influence to the hydraulic oil in the right chamber of hydraulic actuating cylinder: when vibrating reed vibrates to the right, with the hydraulic oil that promotes in the right chamber of hydraulic actuating cylinder, this thrust pressure and hydraulic oil thrust stack from chamber, a hydraulic actuating cylinder left side, its combined action fits brake facing and automobile brake butterfly (dish) on the piston of automobile hydraulic wheel cylinder; And when vibrating reed vibrates left, vibrating reed then will be offset the hydraulic oil thrust pressure in the chamber, a hydraulic actuating cylinder left side, thereby the thrust pressure that the piston that makes the automobile hydraulic wheel cylinder is subjected to reduces, and brake facing and automobile brake butterfly (dish) can not be fitted, like this, constantly fit, loosen between brake facing and the automobile brake butterfly (dish), having caused braking can be by locking.
The utility model is owing to have this kind structure, it is installed in the hydraulic circuit of automobile brake system, the brake system of formed automobile, the locking of braking in the time of can preventing automobile brake effectively, realized the brake anti-blocking function of existing ABS, and this device only mainly is made up of hydraulic actuating cylinder, vibrating reed, electrical motor, camshaft and compression spring, and structure is very simple, and cost is extremely cheap.
