Abstract
The utility model relates to an automobile brake valve second level piston with a semi-automatic variable initial pressure ratio. An air in-out opening (2) with a variable initial pressure ratio is arranged on a middle casing (1), a second level balancing piston sleeve (3) is mounted in the middle casing (1), and a first level-balancing piston (4) is mounted in the middle casing (1). A valve upper casing (6) which is mounted above the middle casing (1), a guiding plastic base (7) and a load transferring push shaft sleeve (10) are mounted on the valve upper casing (6), and a dust-proof bakelite cover (8) is mounted on the valve upper casing (6) and the load transferring push shaft sleeve (10). A push shaft (9) is mounted in the first level balancing piston (4), a rubber spring (11) is arranged between the first level balancing piston (4) and the push shaft (9), and a restoring spring (13) is mounted beneath the first level balancing piston (4) in the middle casing (1). The utility model can make full use of the conversion effect of braking force and adhesive force to shorten braking length and hysteresis, prevent automobile side-slipping and whipping, and lighten intensity of labor and improve stability and smoothness of driving. Further, the utility model is convenient to operate and control, safe and reliable, and has broad adaptability.
Description
Technical field: the utility model relates to the control cock of auto brake system, the variable brake valve of car second piston of pressure ratio just of particularly a kind of S. A..
Background technology: the automobile of air pressure and supercharging air oil brake system in the present technology, brake control valve all is with fixing particular value, control the work and the usefulness of whole brake system of car, and be in specific road conditions condition, do not add the additional facilities automobile with zero load, front and rear wheel braking force and car load braking force are designed into the ideal Distribution characteristic, and each valve automatically regulating seldom often compares P with front and back wheel air pressure
2/ P
1=1 is a constant, decides the distribution of the various performances of automobile brake, automobile one place in operation by the first pressure ratio size of brake control valve, additional facilities is got all the ready, and axle just carries and changes, and distributing with Ideal Characteristics just has very big difference, since heavy duty, the speed of a motor vehicle, road, the variation of weather, outstanding exposure stopping distance and time, hysteresis quality increases, the random servo-actuated of operation control is difficult to be implemented under the comparatively ideal state and carries out, and zero load as a result has well smooth-going, arbitrarily servo-actuated, and heavily loaded stopping distance and time, hysteresis quality is all very big, meets overcast and rainy road to slide, the muddy shape operation control of freezing in road surface, arbitrarily servo-actuated, comformability is better, and Here it is brake control valve is the low pros and cons place of pressure ratio just, roughly unloaded, coordinate, ride comfort is poor, heavy duty stopping distance and time, hysteresis quality is less, and it is better to operate random servo-actuated, brake pedal is heavy, it is sliding to meet overcast and rainy road, muddy freezing, and the road surface is operated controlled poor, loses stability and safe reliability, Here it is brake control valve is the high pros and cons place of pressure ratio just.
Summary of the invention: the purpose of this utility model is to provide a kind of S. A. the variable brake valve of car second piston of pressure ratio just, it is that the valve of a fixed value is made the valve that can be changed into two first pressing ratios, thereby improve comformability that various loadings, the speed of a motor vehicle, road use climatically, operation control, arbitrarily servo-actuated and safe reliability, reduce labor intensity, improve economic travelling speed and benefit.
Formation of the present utility model: by middle shell, secondary dummy piston cover, the one-level dummy piston, the valve upper shell, the guiding plastic seat, dustproof Jiao Gai, push shaft, transmission push shaft cover, rubber spring and retracing spring are formed, variable pressure ratio port 2 is just arranged on middle shell 1, secondary dummy piston cover 3 is installed in the middle shell 1, one-level dummy piston 4 is installed in middle shell 1 and the valve upper shell 6, valve upper shell 6 is installed in above the middle shell 1, guiding plastic seat 7 and power transmission push shaft cover 10 are installed on the valve upper shell 6, dustproof glue lid 8 is installed on valve upper shell 6 and the power transmission push shaft cover 10, push shaft 9 is installed in the one-level dummy piston 4, above push shaft 9 in the groove of one-level dummy piston 4, jump ring 5 is installed, rubber spring 11 is installed between one-level dummy piston 4 and push shaft 9, and retracing spring 13 is installed in one-level dummy piston 4 belows in the middle shell 1.
In push shaft 9 and cylindrical pit that one-level dummy piston 4 cooperates, O RunddichtringO 12 is housed, on one-level dummy piston 4 and cylindrical that middle shell 1 cooperates, O RunddichtringO 12 is arranged, on secondary dummy piston cover 3 cylindricals that cooperate with middle shell 1 and one-level dummy piston 4 and endoporus, O RunddichtringO 12 is arranged.
Compared with the prior art, the utility model can make full use of the conversion effect of braking force and adhesive ability, shortens stopping distance and hysteresis quality, prevent the skid whipping, reduce labor intensity, improve the train stability ride comfort, wide adaptability, the random servo-actuated of operation control, safe and reliable.
