Description

Technical Field

[0001] The utility model relates to the technical field of brake pumps, in particular to a brake pump assembly for a motorcycle. Background Art

[0002] The motorcycle brake pump is an important part of the motorcycle braking system and is used for braking the motorcycle. The brake pump assembly mainly includes a main pump body and a handle. By pressing the handle, the push rod inside the main pump body is driven downward, and the piston column and the retaining spring are pushed downward at the same time, so that the brake oil in the cavity is pushed out through the oil outlet pipe, and the hydraulic pressure pushes the pump piston down to generate friction between the brake pad and the brake disc, forming effective braking, thereby completing the braking operation of the motorcycle.

[0003] After searching, the Chinese patent authorization number CN 217301369 U discloses a motorcycle brake pump assembly. The advantage of the above scheme is that the utility model adopts a plunger-type direct oil pumping method, the stability of the oil-cut brake is good, and the structure is simpler, and the production and processing efficiency and the yield rate are effectively improved. However, the top of the oil chamber of the brake pump assembly is not provided with a corresponding sealing device. When the handle is pressed to push the push rod box to move inside the oil chamber, the brake oil inside the oil chamber is squeezed during driving, so that the brake oil is easy to seep out from the top of the main pump body, thereby causing a waste of brake oil, and it is easy to cause insufficient hydraulic pressure, thereby reducing the braking effect. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a motorcycle brake pump assembly, which solves the problem that the main pump body inside the existing motorcycle brake pump assembly lacks effective sealing ability, which makes it easy for brake oil to leak out during braking, causing insufficient hydraulic pressure and resulting in reduced braking effect.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a motorcycle brake pump assembly, including a brake pump body, a main pump body is installed inside the brake pump body, a connecting block is fixedly installed on the left side of the outer wall of the main pump body, a handle is sleeved on the inner wall of the connecting block, a push rod is installed on the bottom end of the handle through a connecting seat, a symmetrically distributed fixed telescopic rod is fixedly installed on the outer wall of the push rod through a connecting block, and a piston mechanism is installed on the main pump body.

[0006] Preferably, an oil storage tank is fixedly mounted on the outer wall of the main pump body, an oil storage tank is provided inside the oil storage tank, an oil inlet pipe is mounted on the inner wall of the oil storage tank, the oil inlet pipe is fixedly mounted on the outer wall of the main pump body, and the oil inlet pipe is connected to the inside of the main pump body, a box cover is fixedly mounted on the side wall of the oil storage tank by bolts, and a sealing ring is fixedly mounted on the inner wall of the box cover.

[0009] Preferably, the sealing ring is sealingly connected to the inner wall of the oil storage tank through the tank cover.

[0010] Preferably, the push rod is slidably connected to the inner wall of the piston mechanism through a handle, and the push rod seal is slidably connected to the inner wall of the sealing rubber sleeve.

[0011] The utility model provides a motorcycle brake pump assembly, which has the following beneficial effects:

[0012] The motorcycle brake pump assembly is equipped with a sealing rubber sleeve, which is installed on the top of the main pump body, and the sealing rubber sleeve is in contact with the inner wall of the oil chamber. At the same time, the sealing rubber sleeve is sealingly and slidably connected to the outer wall of the push rod, thereby forming an effective sealing effect.

The retaining spring 72 is sleeved on the lower end of the outer wall of the piston cylinder 71, and the sealing rubber sleeve 73 is sleeved on the upper end of the outer wall of the piston cylinder 71.
