The clearance cavity connected with an oil inlet duct (9) is provided with a two-way leather cup (2) or an adjusting piston pair. A one-way valve is disposed on the two-way leather cup (2) or a clearance adjusting piston. A power piston pair is arranged in the piston working cavity. The brake clearance adjusting valve saves maintaining time and maintaining expenses in the process of using an automobile, is convenient to use, integrates adjustment of the brake and the brake clearance in the process of running of the automobile, simultaneously completes adjustment of the brake and the brake clearance, maintains an optimal clearance value all the time, and increases driving safety of the automobile.
Description
Technical field
The utility model relates to the brake clearance adjustment valve that a kind of automobile that is used for hydraulic braking is adjusted the gap of wheel drag automatically.
Background technique
Brake portion is the safety assurance of automobile running; In order to make automobile guarantee best brake clearance (these letters of gap between brake drum and the brake shoe are claimed brake clearance) under steam at any time; Automatic regulating apparatus has just appearred in the sedan car of hydraulic braking; It by allot plate certainly, dial the plate stay cord, dial the plate torsion spring, dial plate stay cord guide plate, the adjustable push rod of brake shoe supporting Xiao, band ratchet forms, when after brake clearance surpasses specified value, braking, dial plate stay cord guide plate and follow brake shoe to expand; Plate is alloted in the dial plate stay cord pulling of utilization solid on brake shoe supporting Xiao certainly; From alloting the ratchet that plate automatically removes to stir the adjustment screw of adjustable push rod, change the active length of adjustable push rod, thereby brake clearance is returned to reference value.But this automatic regulating apparatus only is used for sedan car at present, and the truck of hydraulic braking still leans on artificial adjustment brake clearance.
Summary of the invention
The automobile that the purpose of the utility model provides a kind of hydraulic braking can be adjusted the gap of wheel drag under steam automatically; And let the gap of wheel drag remain on the best gap width, and be the brake clearance adjustment valve that the automobile of all hydraulic braking can both be adorned usefulness.
For realizing above-mentioned purpose, in the valve body of the described brake clearance adjustment of the utility model valve and the valve gap two-way leather cup or piston pair are housed; On two-way leather cup that bypass valve is arranged on the valve body or piston pair, do not have one-way valve, on two-way leather cup that does not have bypass valve on the valve body or piston pair, one-way valve is arranged; On valve body and the valve gap oil duct is arranged.
In order to make wheel drag adjusting play automatically, the two-way leather cup or the piston pair of the described brake clearance adjustment of the utility model valve can move in valve body.
For transmission of power and hydraulic oil smoothly the passing through valve body in of gap when adjusting that guarantees wheel drag; And guarantee that wheel drag can normal brake application; On the valve body of the described brake clearance adjustment of the utility model valve bypass valve is arranged, or on the two-way leather cup of brake clearance adjustment valve or the piston pair one-way valve is arranged.
In order to guarantee the adjustment precision of brake clearance, the spatial volume that the two-way leather cup of the described brake clearance adjustment of the utility model valve or piston pair move in valve body is exactly the movable volume that wheel cylinder guarantees the wheelcylinder piston of best brake clearance.
In order to guarantee best brake clearance, when the described brake clearance adjustment of the utility model valve had bypass valve on valve body, bypass valve can be by-pass hole or one-way valve; When on two-way leather cup or piston pair, one-way valve being arranged, the unfolding mode of one-way valve is spacing top-opening type or pressure pressing type.
The utility model brake clearance adjustment valve simple in structure, be convenient to make, adopted brake clearance adjustment valve after, automobile has in use been practiced thrift the time of repairing; Saved the expense of repairing; Easy to use, can make automobile under steam the adjustment integrator of braking with brake clearance, accomplish simultaneously; And remain on the best gap width, improved the driving safety of automobile.
Description of drawings
Fig. 1 is the structural representation that the sectional view of bypass valve is arranged on the valve body of the utility model brake clearance adjustment valve.
Fig. 2 is the structural representation that the sectional view of one-way valve is arranged on the interior two-way leather cup of the valve body of the utility model brake clearance adjustment valve.
Embodiment
In the valve body 1 of the utility model brake clearance adjustment valve and the valve gap 2 two-way leather cup 3 or piston pair are housed; On two-way leather cup 3 that bypass valve 5 is arranged on the valve body 1 or piston pair, do not have one-way valve, on two-way leather cup 3 that does not have bypass valve 5 on the valve body 1 or piston pair, one-way valve is arranged; On valve body 1 and the valve gap 2 oil duct is arranged.One-way valve is made up of the middle part of two-way leather cup 3 or middle part, valve 7, spring 8, card 9, the oilhole 6 of piston pair;
In order to make wheel drag adjusting play automatically, two-way leather cup 3 or piston pair can move in valve body 1.In order to guarantee brake clearance transmission of power and hydraulic oil the passing through smoothly in valve body 1 in when adjustment, and the assurance wheel drag can normal brake application, bypass valve 5 is arranged on the valve body 1, or on two-way leather cup 3 or the piston pair one-way valve is arranged.In order to guarantee the adjustment precision of brake clearance, the spatial volume that two-way leather cup 3 or piston pair move in valve body 1 is exactly the movable volume that wheel cylinder guarantees the wheelcylinder piston of best brake clearance.In order to guarantee best brake clearance, when on valve body 1, bypass valve 5 being arranged, bypass valve 5 can be by-pass hole or one-way valve; When on two-way leather cup 3 or piston pair, one-way valve being arranged, the unfolding mode of one-way valve is spacing top-opening type or pressure pressing type.
The utility model brake clearance adjustment valve is after installing on the automobile of hydraulic braking; When the gap of wheel drag surpasses the braking of regulation back; Hydraulic oil gets in the valve body 1 from oil duct 4; Promote two-way leather cup 3 or piston pair and move forward, promote hydraulic oil and get into wheel cylinder, outwards move and promote wheelcylinder piston.After two- way leather cup 3 or 3 piston pairs move to valve body 1 or valve gap 2; Receive the qualification of valve body 1 or valve gap 2 no longer mobile; Have two kinds of situation this moment: one, bypass valve 5 is opened, and hydraulic oil then gets into wheel cylinder through oil channel 4 again through bypass valve 5, and the piston that continues the promotion wheel cylinder moves outward; Back down brake shoe, produce braking.Two, one-way valve opens, hydraulic oil then gets into wheel cylinder through oil channel 4 again through oil-through hole 6, and the piston that continues the promotion wheel cylinder moves outward, backs down brake shoe, produces braking.Behind the take-off the brake, under the effect of brake shoe return spring, two-way leather cup 3 or piston pair travelling backwards, have two kinds of situation this moment again: one, bypass valve 5 cuts out when two-way leather cup 3 or piston pair travelling backwards; Two, oilhole 6 is closed under the effect of one-way valve.Hydraulic oil is under the effect of brake shoe return spring; Continue to promote two-way leather cup 3 or piston pair travelling backwards; 4 mouthfuls of places of oil duct up to valve body 1 or valve gap 2 are no longer mobile; The hydraulic oil that get in the valve body 1 this moment can not all flow out outside the valve body 1, and the stroke of travelling backwards of the piston of wheel cylinder has been dwindled, and has reached the purpose of automatic adjustment brake clearance.
