Abstract
The utility model discloses a novel pressure-boosting hydraulic pipeline device which comprises an air cylinder arranged on a relay valve assembly, wherein a big piston and a piston rod connected with the big piston are arranged in the air cylinder; an exhaling and aspirating pipe is arranged in the piston rod; a plastic guiding seat and a piston bolt are arranged at the end part of the piston rod which is connected with a hydraulic pump on an air cylinder upper cover above the air cylinder; an oil nozzle and an oil inlet valve are arranged on the hydraulic pump; a bleed screw and a connector of an oil inlet pipe are further arranged; and a sensing alarm and the bleed screw are arranged on the air cylinder upper cover. The device is suitable for automobile braking and particularly for heavy automobile braking.
Description
Technical field
The utility model relates to a kind of automobile braking device, especially relates to a kind of later-model pressurization hydraulic pepe installation of supercharging air.
Background technology
The brake part of automobile is the big problem that is related to driving and lives and properties, the particularly brake of heavy motor vehicle, there is the problem of the mutability of omnidistance lock torque in the lock torque output reliability of some brake gears and the galloping in existing heavy motor vehicle on the market, and the defective of the commonality of auxiliary spare and accessory parts.
Summary of the invention
The purpose of this utility model is the defective that exists on the brake gear at above-mentioned heavy motor vehicle to provide a kind of reasonable in design, omnidistance braking reliability and the good later-model pressurization hydraulic pepe installation of security and stability.
In order to achieve the above object, the utility model is mainly finished by the following technical solutions.The utility model mainly is made up of the cylinder block of being located on the relay valve assembly, be provided with big piston and coupled piston rod in the cylinder block, be provided with respiration tracheae in the piston rod, the end of piston rod is provided with plastics guide holder and piston rod bolt, piston rod is connected at the hydraulic pump body that covers on the cylinder block of top of cylinder block, hydraulic pump body is provided with oil nozzle and inlet valve, also is provided with air bleed screw and oil inlet pipe union.On cylinder block, cover and be provided with induction alarm device and air bleed screw.
The utility model compared with prior art has following tangible advantage and innovation.(1) reasonable in design.The utility model is imported pressurized air by air pressure control element relay valve to air chamber servo cylinder inner chamber, promote the piston rod be attached thereto through big piston, Fast Compression in hydraulic pump body again, make braking liquid produce the output hydraulic pressure that requires, touch bone simultaneously and put check valve and open and close compensation negative pressure space inside brake liquid, in case occur leaking, then piston moves ahead when output hydraulic pressure, impel of the warning of electromagnetic induction annunciator, thereby guarantee the identification of safe reliability the inefficacy of hydraulic braking state.(2) compact conformation.The utility model has increased a check valve on oil inlet, can suitably reduce to brake the deposit space of fluid; Utilize big piston to drive piston rod,, simplified the structure and the technology input of product by piston rod directly supercharging in the pump housing; Servo-unit cylinder respiration tracheae embedding structure makes assembly integral rationally distributed and succinct, saves installing space.(3) human oriented design.The assembly space of different automobile types is narrow and small and outward appearance is made every effort to succinct and the minimizing auxiliary volume, possesses warning function, thereby reaches widely applicable, structural refinement, the requirement of safety arrestment and stabilization.
The utility model is applicable to the braking of automobile, is specially adapted to the braking of heavy motor vehicle.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
