Description
One, technical field
The utility model relates to a kind of hydraulic brake, is applicable to the braking device of motorcycle, electric bicycle.
Two, background technique
In the patent No. is ZL200320123207.5, discloses " a kind of hydraulic brake " patented technology, employing be the structure that master cylinder drives two wheel cylinders, its complex structure, it is difficult to make, the more high deficiency of cost.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to manufacture, and good braking effect drives the hydraulic disc brake device of the motorcycle of big pump with little pump.
Technological scheme that the purpose of this utility model adopts is, a kind of hydraulic disc brake device of motorcycle, include pressurizing cylinder is arranged in the body, compensation oil pocket, large tank, the porose connection pressurizing cylinder of chamber wall of one end large tank of its body, the chamber wall has one-way valve between pressurizing cylinder and the compensation oil pocket, assembling has the big piston of oil sealing in the large tank cylinder, big piston one end face has push rod, the hole that push rod passes the large tank lid that is contained in body other end dress is connected with the movable fixed plate, in the outer support arm brake block fixed plate is arranged on the extra-organismal U type frame.
The utility model, the chamber wall of large tank has outlet valve.
The utility model, the push rod cylindrical between big piston one end face and the large tank lid has return spring.
The utility model has small piston in the pressurizing cylinder cylinder.
The utility model, the cylindrical of large tank lid is embedded with seal ring, interior circle is embedded with seal ring, and the body inner round wall groove at circle place, the outer end of large tank lid is embedded with jump ring.
The utility model, the corresponding end face of brake block fixed plate and movable fixed plate is equipped with brake block.
Use the utility model, when braking force acts on small piston by transfer mechanism, small piston is motion forward in pressurizing cylinder, simultaneously the brake medium is produced pressure, brake medium passing hole channel enters large tank, simultaneously pressure is put on the big piston, because the big piston area is bigger than small piston, according to the hydraulic press principle, the proportional increase of the thrust that on big piston, produces, under the thrust of this increase, big piston moves right, promote push rod simultaneously and brake block moves to right, make it and another fixedly the brake block distance produce braking action near rotation to wheel.In small piston travels forward process, be communicated with small oil tank and bottle up the brake medium back flow with the closed check valve that compensates oil pocket, guaranteed the transmission of the airtight and braking force of oil cylinder; After braking force was eliminated, small piston was made returning movement, and the brake medium of compensation oil pocket can flow into the loss of pressurizing cylinder compensation brake medium under vacuum suction; By the effect involution original position of return spring, the brake block distance on moving brake block of movable fixed strip and the fixed plate widens big piston simultaneously after pressure disappears, and braking force disappears thereupon.Outlet valve on the large tank can be got rid of the air in the brake medium, to guarantee effective transmission of braking force.
In use, fixed plate is connected with vehicle frame, and at fixed plate one end wear compensation device is housed, and can guarantee that brake block still can produce enough frictional force in certain abrasion scope.
The utlity model has with the big pump of little pump band, braking force increases exponentially, the advantage that braking efficiency improves.Pressurizing cylinder is communicated with the direct of large tank, make and apparatus structure compacter, further increased the reliability and the traveling security of brake.
