Abstract
The utility model discloses a motorcycle upper pump assembly. The motorcycle upper pump assembly comprises an upper pump shell body, a handle and a half cover, wherein the handle and the half cover are connected with the upper pump shell body. An oil cup and a plunger piston cavity are formed in the upper pump shell body. A plunder piston, a front-and back packing cup and a return springs are arranged inside the plunger piston cavity. An opening of the oil cup is sealed by an oil cup gasket, and the oil cup gasket is fixed through the oil cup cover in a pressing mode. The motorcycle upper pump assembly has the advantages that the oil cup is rectangular, the length direction of the oil cup is the same as the central line direction of the plunger piston cavity, and the length of the oil cup is not smaller than 1/2. The motorcycle upper pump assembly is optimized in structure, and compared with a traditional motorcycle upper pump assembly, the motorcycle upper pump assembly improves the oil storage amount of the oil cup and prolongs the service life of the oil cup gasket.
Description
Technical field
The utility model relates to a kind of motorcycle part, is specifically related to pump assembly on a kind of motor bike.
Background technology
In autobicycle, mini-motorcycle, upper pump assembly and lower pump assembly combine for controlling brake, so its service life and quality are very crucial, and its direct relation motorist's safety.Pump assembly on traditional motor bike, owing to affected by installing space, the aspect ratio of its upper pump case lubricating cup design is generally 1/3 left and right, and the lubricating cup reserves are less, need to maintain more continually oiling; In addition, the structure of lubricating cup pad and materials'use neither be desirable especially, affected the service life of lubricating cup pad.In a word, pump assembly on traditional motor bike, the lubricating cup reserves are less, and the lubricating cup pad is shorter service life, so its service life and quality also are affected, the motorist is caused to a certain extent potential safety hazard.
Summary of the invention
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of structure optimization, compares pump assembly on the motor bike that tradition improved lubricating cup reserves and lubricating cup pad service life.
The utility model is implemented by the following technical programs:
Pump assembly on motor bike, comprise pump case and the handle and the Ban Gai that are connected with upper pump case, upper pump case is established lubricating cup and plunger cavity, establish plunger, front and back leather cup and pull back spring in plunger cavity, the lubricating cup opening is sealed by the lubricating cup pad, and the lubricating cup pad is fixed by oil cup cap, it is characterized in that: described lubricating cup is rectangular shape, the length direction of lubricating cup is identical with the centerline direction of plunger cavity, and the aspect ratio of lubricating cup is not less than 1/2.The line of centers of lubricating cup on Width is to the line of centers that partly covers direction and depart from plunger cavity.Described lubricating cup spacer has the pad of continuous U-shaped bending shape.Described lubricating cup pad adopts ethylene propylene diene monomer (EPDM) material.
Pump assembly on the motor bike of employing technique scheme, compare with tradition, and its structure has obtained optimization, useful technique effect is: 1. under the constant prerequisite of lubricating cup length, improved the aspect ratio of lubricating cup, namely increased the width of lubricating cup, the oil reserve of lubricating cup gets a promotion; 2. for avoiding the increase of lubricating cup width to have influence on the installation of pump assembly, adopted the line of centers of lubricating cup on Width to the technical scheme of partly covering direction and depart from the plunger cavity line of centers; 3. the lubricating cup spacer has the pad of continuous U-shaped bending shape, and the action that improves the lubricating cup pad is flexible, and then improves lubricating cup pad service life; 4. the lubricating cup pad adopts ethylene propylene diene monomer (EPDM) material, improves lubricating cup pad service life.In sum, pump assembly on motor bike of the present utility model, compare tradition and improved lubricating cup reserves and lubricating cup pad service life, guarantees motorist's safety.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is shape assumption diagram of the present utility model,
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
Describe details and the principle of work of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
as shown in the figure, pump assembly on motor bike of the present utility model, comprise pump case 1 with the handle 2 that is connected with upper pump case 1 and partly cover 3, upper pump case 1 is established lubricating cup 4 and plunger cavity 9, be provided with plunger 13 in plunger cavity 9, front leather cup 12, rear leather cup 11 and pull back spring 10, lubricating cup 4 openings are sealed by lubricating cup pad 8, lubricating cup pad 8 is fixed by oil cup cap 7, described lubricating cup 4 is rectangular shape, the length direction of lubricating cup 4 is identical with the line of centers of plunger cavity 5 directions, the aspect ratio of lubricating cup 4 is not less than 1/2, the line of centers 6 of lubricating cup 4 on Width is to the line of centers 5 that partly covers 3 directions and depart from plunger cavity, described lubricating cup pad 8 has the pad of continuous U-shaped bending shape, described lubricating cup pad 8 adopts ethylene propylene diene monomer (EPDM) material.
