Abstract
The utility model relates to an anti-lock braking system for automobiles, belonging to a hydraulic pressure anti-lock braking system for light trucks. The utility model is characterized in that a cylindrical gear ring with sixty-eight teeth is respectively arranged at each small end of four wheel hubs in the axial direction; a wheel speed sensor is arranged on a base plate of a brake; Point five mm interval is arranged between the probe of the wheel speed sensor and the cylindrical gear ring. The utility model has the advantages of safe brake, more reliable braking performance, avoidance of slide and turning over resulting from emergency brake of light trucks, assurance of safety of vehicles and drivers by avoiding total lock of tires and producing strong lateral adhesive power when conducting emergency brake on the bisectional road, butt joint road and other road surfaces with low grip power.
Description
Technical field
The utility model relates to the automotive wheel anti-skid brake system, specifically light truck hydraulic pressure anti-skid brake system.
Background technology
When automobile brake, if the wheel lockup slippage, the side direction adhesive ability between wheel and road surface is with complete obiteration.If just front-wheel (wheel flutter) is braked the locking slippage and trailing wheel is also rolling, automobile will lose steering capability.If just trailing wheel is braked the locking slippage and front-wheel is also rolling, even be subjected to little side direction exciting force, automobile also will produce sideslip (whipping) phenomenon.These all very easily cause serious traffic accident.Therefore, automobile does not wish that at glancing impact wheel braking arrives the locking slippage, but wishes that wheel braking is to the sliding state of limit rolling.
Learn that by test the sliding ratio of automotive wheel had maximum adhesion value at 15%～20% o'clock between tire and road surface.So in order to give full play to this potential cohesive resistance between tire and road surface, on most of vehicles, all equipped anti-skid brake system (Antilock Brake System) at present, be called for short ABS.
The ABS technology is used for many years abroad, and only is used for manned vehicle mostly at home.The commercial vehicle/comm..vehicle field is equipped the ABS system except part vehicle in heavily blocking at home, and other commercial vehicle/comm..vehicle is not equipped with this system substantially.And the vehicle of coupling ABS all is a compression air brake in heavily blocking.
The hydraulic brake system of the light card of traditional ABS that do not match is softer, makes the occupant feel comfortable.But when on the low road surface of adhesive rate, carrying out emergency braking, very likely can cause accidents such as whipping, overturning, harm occupant's life security.
The utility model content
The purpose of this utility model is: when solving the light truck emergency braking, very likely can cause accident problems such as whipping, overturning, a kind of light truck hydraulic pressure anti-skid brake system that is applicable to light truck is provided.
Concrete structural development scheme is as follows:
Light truck hydraulic pressure anti-skid brake system comprises vacuum booster band brake master cylinder, drg, four wheel speed sensors, electronic control mechanism and pressure regulating mechanisms.
Also comprise four cylindrical wheel formula gear rings, each cylindrical wheel formula gear ring is sheathed on the axial small end of four wheel naves respectively, and is interference fit, and the number of teeth of each cylindrical wheel formula gear ring is 68;
Wheel speed sensors is located on the brake support plate, and the gap between wheel speed sensors probe and the cylindrical wheel formula gear ring is 0.5 millimeter;
Electronic control mechanism and pressure regulating mechanism are set up on the vehicle frame two crossbeam assemblies by propping up.
Described pressure regulating mechanism is the four-way formula, and two drgs of front-wheel are double-collar and shoe type, and two drgs of trailing wheel are two-way double-collar and shoe type; Brake dimensions is Φ 320 * 75, and the wheel cylinder cylinder diameter is Φ 30.16.The master brake cylinder cylinder diameter is Φ 31.75.
The utility model has carried out design processing to wheel hub, in order to the assembling gear ring, secondly, brake support plate is designed processing, in order to the assembly wheel speed sensors, on two crossbeam assemblies, weld support in order to assembling charged sub-control mechanism of hydraulic control pump and pressure regulating mechanism assembly, and the hydraulic tubing and the electrical harness of coupling brake system; It is reasonable in design, and is simple in structure, and fitting operation is convenient.The utility model low attached, split and road surface that adhesive ability such as butt joint is low on when carrying out emergency braking, make tire be unlikely to whole lockings, and produce bigger side direction adhesive ability, reach the purpose of safety that makes automobile and occupant.The application of this device, the especially application on the HFC1045KRD of short wheelbase type goods carrying vehicle have been guaranteed the braking safety of light truck to make light truck have more failure-free deceleration and stopping performance.
Description of drawings
Fig. 1 is used for light truck brake piping and control path scheme drawing for the utility model,
Fig. 2 is that wheel hub, gear ring cooperate scheme drawing with wheel speed sensors,
Fig. 3 is the partial enlarged drawing of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, light truck hydraulic pressure anti-skid brake system comprises vacuum booster band brake master cylinder 6, drg, four wheel speed sensors 1, electronic control mechanism 4 and pressure regulating mechanisms 5.
Also comprise four cylindrical wheel formula gear rings 3, each cylindrical wheel formula gear ring 3 is set with the axial small end in four wheel naves 2, and is interference fit, and the number of teeth of each cylindrical wheel formula gear ring 3 is 68;
Wheel speed sensors 1 is satisfied with on the brake support plate, and the gap between wheel speed sensors probe and the cylindrical wheel formula gear ring 3 is 0.5 millimeter;
Electronic control mechanism 4 and pressure regulating mechanism 5 are installed on the vehicle frame two crossbeam assemblies by support.
Pressure regulating mechanism is the four-way formula, and two drgs of front-wheel are double-collar and shoe type, and two drgs of trailing wheel are two-way double-collar and shoe type; Brake dimensions is Φ 320 * 75, and the wheel cylinder cylinder diameter is Φ 30.16.The master brake cylinder cylinder diameter is Φ 31.75.
Join from two oil outlets of master brake cylinder 6 and the oil inlet of pressure regulating mechanism 5, each hydraulic fluid port is divided into two oil outlets then, and four oil outlets are connected on the drg of four wheels.And the signal wire (SW) of wheel speed sensors 1 will be connected on the electronic control mechanism 4 in order to provide wheel speed information to electronic control mechanism 4.
This light truck hydraulic pressure anti-skid brake system has self-checking function, promptly when start, total system is carried out self check, in case pinpoint the problems, its light truck hydraulic pressure anti-skid brake system indicator lamp is with Chang Liang; If detect normally, then light truck hydraulic pressure anti-skid brake system indicator lamp goes out.
Low attached, split and road surface that adhesive ability such as butt joint is low on when carrying out emergency braking, wheel speed sensors of the present utility model reacts rapidly, and send signal to electronic control mechanism, after electronic control mechanism is handled it, pressure regulating mechanism is sent the signal of control presssure, after pressure regulating mechanism is carried out, brake-pipe pressure is regulated, make tire be unlikely to whole lockings, and produce bigger side direction adhesive ability, reach the purpose of safety that makes automobile and occupant.
