Description
Technical field
The utility model relates to the oil pressure disk type brake used in bicycle, Electrical Bicycle and motor bike, is called for short hydraulic disc brake.
Background technology
Bicycle, Electrical Bicycle and motor bike widely use hydraulic disc brake, the parts of these vehicle indispensabilities, at present conventional hydraulic disc brake is due to the reason of project organization and manufacture, the following deficiency of easy generation: one is, the upper pump easy oil leakage of current hydraulic disc brake, reason is that the upper pump of the hydraulic disc brake of open by design has two movable rubber seal, during work, these two seal rings do not stop to move back and forth wearing and tearing always, with outside only every a simple O RunddichtringO or a trumpet type seal ring, such easy oil leakage.Two are, upper pump casing is with an oil storage cup, and oil storage cup has and more is in communication with the outside place, and difficult sealing is to ensure.Three are, the friction lining of pump and the gap adjustment difficulty of disc under open hydraulic disc brake.For the problems referred to above, Chinese patent ZL201420300238.1 gives a kind of scheme of solution, and conveniently can adjust the gap between friction lining and disc, conveniently can adjust again the angle of handle.But structurally slightly complicated.
Utility model content
For the defect that above-mentioned existing technology exists, the closed adjustable oil of the utility model upper pump object of stopping is: pump on the hydraulic disc brake providing a kind of closed oil circuit, more simple mode is adopted to reach the gap that can conveniently adjust between friction lining and disc, conveniently can adjust again the angle of handle, simplify part, reduce productive costs.
It is such for realizing the technical solution of the utility model:
A kind of closed adjustable oil is stopped upper pump, comprise adjusting nut, adjustment screw rod, limit buckle, adapter, tune fork, adjust fork screw and protecting sleeve, the shape of described adjusting nut resembles T-shaped, or resemble criss-cross, centre has a screw hole run through that adjustment screw rod is housed, and the two terminal circle cylinder vertical with screw hole is enclosed within the circular hole of handle; The front end of adjustment screw rod is resisted against in the pit of piston, and the spinning in and out of adjustment screw rod change the oil storage volume of oil cylinder pipe; Limit buckle one end connects piston, and the other end connects adjustment screw rod, and limit buckle makes piston and adjustment screw rod be abutted together and can not separate; One end connected pipes of described adapter, the other end and oil cylinder pipe are spirally connected, and there is an oiling screw centre; The jaw of described tune fork is resisted against on adjusting nut or is resisted against on handle, defines the position of adjusting nut and handle retrogressing, adjusts the centre of fork porose, is fixed in upper pump case by pin, adjusts the lower end of fork that tune fork screw is housed; Described tune fork screw is contained in the lower end of adjusting fork, and the one end inside it withstands in pump case, and its tail end has the groove can puted forth effort for screwdriver, or its afterbody is fixed on a knob; Described protecting sleeve makes with rubber or plastics, and have elasticity, be wrapped in the head of adapter and upper pump case, there is the convex tendon of ring-type its inside, and this convex tendon is strangled in the gap between adapter and upper pump case.The two terminal circle cylinder of described adjusting nut has the minor axis of protrusion, this minor axis leans against on the jaw of tune fork; The shape of adjusting nut or a cylinder, centre is screw.Described limit buckle and the connection mode of piston are spirally connected or rivet or snapping or limit buckle itself and piston combine together, wraps the round end of adjustment screw front end in the mode of riveting.The spinning in and out of described adjustment screw rod change the oil storage volume of oil cylinder pipe, can not change the angle of handle.The spinning in and out of described tune fork screw change the oil storage volume of oil cylinder pipe, change the angle of handle simultaneously.Or by the distance between knob screw adjustment handle and upper pump case; Or add on handle and prolong a projecting block, adjust fork to withstand on projecting block, adjust the spinning in and out of fork screw just to change the oil storage volume of oil cylinder pipe, change the angle of handle simultaneously.
The beneficial effects of the utility model are, relative to the hydraulic disc brake of general use at present, decrease the possibility of leakage of oil, improve result of use, simplify part, reduce productive costs.
