Problems solved by technology

[0002] The conventional lever-type handbrakes have problems such as exposed oil cups and blockage of oil passages. Because the exposed oil cups have disadvantages in appearance, they cannot achieve a streamlined appearance and will generate unnecessary wind resistance.
And because the handle seat is integrally formed by casting, forging and other processing methods, and then drilled and milled out of the accommodating chamber by a lathe, after the periphery of the accommodating chamber is processed, the material is in contact with the hydraulic oil for a long time, and is easily affected by the hydraulic pressure. Oil erosion produces debris, which causes qualitative changes in the material around the hole in the handle seat, and finally causes the overall structure of the handle seat to be damaged, or because the debris blocks the oil circuit, the sensitivity of the brake is reduced or the brake fails. Potential safety hazards for riders

Embodiment Construction

[0017] A kind of handbrake device of the present invention is suitable for the handbrake structure of the handlebar vehicle, the technical means adopted and the purpose achieved are hereby briefly described as follows with the best embodiment in conjunction with the drawings:

[0018] see figure 1 and refer to figure 2 , image 3 As shown, a handbrake device is combined with the handle 10 of the handlebar vehicle, and includes a handle seat 20, an oil bag 30, a syringe 40, and a bag cover 50, wherein:

[0019] The handle base 20 is provided with an accommodating chamber 21 for accommodating the oil bag 30. The rear side of the accommodating chamber 21 has a clamping portion 211 that clamps the capsule cover 50 so as not to fall off naturally. The clamping portion 211 is formed by a pair of The male-female combination bolt 22 wraps and clamps the capsule cover 50 while fixing the handle 10 so as not to fall off;

[0020] The oil bag 30 combines the bag cover 50 to accommoda...

Abstract

A hand brake device is combined with a handlebar of a handle type vehicle and comprises a handlebar seat, an oil sac, a needle cylinder and a sac cover, wherein an accommodation chamber for accommodating the oil sac and a clamping part arranged on the rear side of the accommodation chamber are arranged on the handlebar seat; and the oil sac is combined with the sac cover to accommodate the needlecylinder in the body. The oil sac comprises an oil groove, a small beam ring and a large beam ring; the needle cylinder comprises a snap ring, a hollow oil chamber and an oil outlet; and the sac cover comprises a central through hole through which the needle cylinder penetrates, ring grains combined with the oil sac as well as an oil injecting port. By means of the shape, the structure and the combination of the shape and the structure, the handle type oil pressure hand brake device with the advantages of attractiveness in appearance, reduced wind resistance and capability of ensuring the smoothness of a brake oil channel is realized.

Description

technical field [0001] The invention provides a handbrake device, especially a hydraulic handbrake device suitable for a handlebar vehicle. Background technique [0002] The conventional lever-type handbrakes have problems such as exposed oil cups and blockage of oil passages. Because the exposed oil cups have disadvantages in appearance, they cannot achieve a streamlined appearance and will generate unnecessary wind resistance. And because the handle seat is integrally formed by casting, forging and other processing methods, and then drilled and milled by a lathe to form the accommodation chamber, after the periphery of the accommodation chamber is processed, the material is in contact with hydraulic oil for a long time, and is easily affected by hydraulic pressure. Oil erosion produces debris, which causes qualitative changes in the material around the hole in the handle seat, and finally causes the overall structure of the handle seat to be damaged, or because the debris ...
