Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to a combined oil pressure upper pump and a line-pulled oil disc suitable for a horizontal handlebar. Background Art

[0002] There are currently two control transmission methods for disc brakes, namely cable disc brakes and hydraulic disc brakes.

[0017] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0018] Reference Figure 1-3 A combined hydraulic upper pump and cable-pull oil disc suitable for a horizontal handlebar comprises an upper pump body 1, a clamping frame 6 is provided on one side of the upper pump body 1, a handle 2 is provided between the upper pump body 1 and the clamping frame 6, a left brake cable 5 and a right brake cable 4 are provided on both sides of the upper pump body 1, a first oil pump 9, a second oil pump 15, a first oil reservoir 17 and a second oil reservoir 18 are provided on one side of the pump body 1, and two symmetrically arranged oil pipe outlets 16 are provided on one side of the pump body 1.

[0019] The upper pump body 1 and the clamping frame 6 are threadedly connected to the locking handle 2 via mounting bolts 7 .

[0020] The upper pump body 1 is provided with a first external connection port and a second external connection port on its exterior.

[0021] The second oil pump 15 is communicated with the first oil reservoir 17 , and the second oil pump 15 is communicated with the first external port, and the second oil pump 15 is connected to the right brake cable 4 .

[0022] The first oil pump 9 is communicated with the second oil reservoir 18 , and the first oil pump 9 is communicated with the second external port, and the first oil pump 9 is connected to the left brake cable 5 .

[0023] The first external port and the second external port are communicated with two oil pipe outlets 16 respectively, and the two oil pipe outlets 16 are connected to the front wheel brake disc and the rear wheel brake disc of the bicycle respectively.

[0024] The brake line of this application pulls the piston inside the oil pump, driving the hydraulic oil from the oil pump to the external port, and connecting to the front wheel or rear wheel brake oil disc through the oil pipe, thereby driving the piston inside the oil pump to move, and the piston then pushes the brake pad to clamp the disc brake disc to achieve the braking function;

[0025] The function of the oil reservoir is to adjust the oil pressure in the first oil reservoir and the second oil reservoir. The brake pads are constantly worn during use, and hydraulic oil needs to be replenished from the oil reservoir through the oil pump into the oil circuit to compensate for the pressure changes caused by the wear of the brake pads.
