Abstract
The utility model relates to a brake master cylinder with an adjustable proportional valve. The brake master cylinder is provided with the adjustable proportional valve which is positioned at the outlet of the brake master cylinder, wherein an output end of the proportional valve is provided with a regulating screw and a regulating spring, one end of the regulating spring is in contact with the regulating screw and the other end of the regulating spring is in contact with the rear end of a piston of the proportional valve. The spring action of the proportional valve on the piston can be indirectly changed through using the regulating screw to change the resistance force of the regulating spring, and eventually achieve the purpose of regulating an inflection point distributing relative braking force according to different types. The brake master cylinder with the adjustable proportional valve can meet the requirements of vehicles with different shaft distances or different loading capacities.
Description
Technical field
The utility model relates to a kind of hydraulic brake master that is applicable to automobile back wheel, relates in particular to a kind of master brake cylinder with adjustable apportioning valve.
Background technology
The hydraulic vehicle braking apportioning valve generally is to be series in the hydraulic vehicle braking trailing wheel brake piping, and its effect is the ratio of keeping between the front and rear wheel brake piping, prevents that automobile from producing the whipping phenomenon at glancing impact generation rear lock.The apportioning valve and the master brake cylinder of many vehicles are set together, and replace independent apportioning valve assembly.This master brake cylinder has two independences or two apportioning valve, and each apportioning valve is positioned at a master cylinder outlet of leading to rear brake, and is identical with the part of independent apportioning valve.The master brake cylinder of general band apportioning valve has only a flex point, and it only is fit to a kind of vehicle.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of master brake cylinder that can satisfy the braking of different automobile types trailing wheel.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is the apportioning valve that is provided with on master brake cylinder with adjustable, apportioning valve is positioned at the outlet of master brake cylinder, the mouth of described apportioning valve is provided with adjusts screw rod and regulating spring, adjust screw rod and regulating spring one end in contact, the back end in contact of the regulating spring other end and apportioning valve piston, change the drag of adjusting spring by adjusting screw rod, change the size of apportioning valve action of the spring on piston indirectly, thereby finally reach the purpose of adjusting flex point, realize distributing corresponding braking force by dissimilar differences.
Because the utility model is provided with on master brake cylinder with adjustable apportioning valve, can be according to the wheelbase of different vehicles, adjust screw rod by manual regulation, adapt with it, to reach desirable braking effect, therefore, this with the master brake cylinder of adjustable apportioning valve applicable to disalignment apart from or the demand of the vehicle of different load carrying abilities.
Description of drawings
Fig. 1 is the integral structure figure of a kind of embodiment of the adjustable apportioning valve master brake cylinder of the utility model band.
Fig. 2 is with the structure enlarged drawing of adjustable apportioning valve among Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, be arranged on the outlet of master brake cylinder 2, be with adjustable apportioning valve 1 to comprise apportioning valve and apportioning valve adjustment structure with adjustable apportioning valve 1.Apportioning valve comprises valve body 3, piston 6, valve seat 7, valve 8, valve spring 9, apportioning valve spring 10.The apportioning valve regulating mechanism comprises adjusting screw(rod) 4 and regulating spring 5, adjusts screw rod 4 and regulating spring 5 one end in contact, and the back end in contact of regulating spring 5 other ends and apportioning valve piston 6 is adjusted screw rod and is provided with seal ring 11.
This is with the master brake cylinder of adjustable apportioning valve, adjust adjustable apportioning valve according to different vehicles: in the automobile zero load or when valve is used for compact car, tighten the adjustment screw rod with hex spanner, spring is adjusted in compression, make the adjustment spring apply certain pressure at the mouth of apportioning valve, when automobile brake, braking liquid by master brake cylinder output is passed to rear wheel cylinder through apportioning valve piston aperture and by brake piping, because apportioning valve is the piston that adopts difference footpath formula structure, the input end diameter of piston is less than the mouth diameter of piston, according to Pascal's law, then have F go out＞F goes into, and applied certain pressure at mouth because adjust spring again, so hydraulic pressure increases to when not high, piston moves valve closing after just, and after this pressure of mouth will increase in proportion; Fully loaded or when valve is used for Oversize vehicle when automobile, unscrew the adjustment screw rod with hex spanner, make and adjust spring, so when brake fluid pressure need increase to high value in the mouth reaction force attenuation, piston just begins to move to right valve closing, and after this pressure of mouth also will increase in proportion.
Claims (2)
1, a kind of master brake cylinder with adjustable apportioning valve, comprise apportioning valve (1) and master brake cylinder (2), apportioning valve (1) is positioned at the outlet of master brake cylinder (2), the mouth that it is characterized in that described apportioning valve (1) is provided with adjustment screw rod (4) and regulating spring (5), adjust screw rod (4) and regulating spring (5) one end in contact, the back end in contact of the piston (6) of regulating spring (5) other end and apportioning valve (1).
