Description

Oil pressure brake device of oil circuit

Technical Field

The utility model relates to the technical field of brake assistance, in particular to an oil-pressure brake device of an oil circuit.

Background

Along with the demand of people for riding feeling higher and higher, bicycles and electric bicycles can replace mechanical disc brake or V brake with oil pressure disc brake more and more. So the oil pressure disc brake in the market is more and more popular. However, the oil pressure disc brake in the current market has a disadvantage that an H-shaped oil way is used, an oil inlet of the oil way caliper, an oil outlet and two cylinders of the large caliper and the small caliper are distributed on four corners of the H-shaped oil way, the oil way flows in from the oil inlet, flows through the middle of the H-shaped oil way, and finally flows out from the oil outlet. When the oil is injected, the air in the two caliper cylinders is difficult to discharge, so that the quality problems of oil pressure, braking force reduction and the like are caused. In addition, when the oil is replaced by maintenance, the old oil in the two caliper cylinders is difficult to replace.

As shown in fig. 1, when the oil disc of the H-shaped oil way is used for filling oil into the two calipers, the oil discharge port 5a is blocked, vacuum is pumped from the oil inlet 4a, then after the air in the two calipers is completely pumped away, the oil is filled into the oil inlet 4a, and at the moment, the oil is filled from the oil inlet 4a into the cylinder body of the right calipers under the negative pressure state and flows into the right cylinder body 4c through the oil way of the right first oil way 4 b; the left side clamping member 5 is connected to the right side clamping member 4 by means of an O-ring 2. The left caliper 5 is also in a negative pressure state after the air is drawn out, and when the oil is injected, the oil flows in from the oil inlet 4a, flows through the right second oil passage 4d, the left second oil passage 5d, and the left first oil passage 5b, and then enters the left cylinder 5c. Thus, the oil fills the two caliper cylinders; when the hydraulic oil pump is used, high-pressure hydraulic oil still flows in from the oil inlet 4a, passes through the same oil way, and finally pushes the first piston 6a and the second piston 6b in the cylinder body to perform braking action; however, if the air in the two calipers is not completely pumped during oil injection, air remains in the cylinder bodies of the two calipers after oil injection, and the air can be compressed after the use, so that the braking function is disabled.

In addition, when the H-shaped oil way is maintained, an injector of which the oil drain port 5a of the left caliper 5 is communicated with the outside is opened, then oil is filled into the two calipers from the injector, hydraulic oil flows in from the oil drain port 5a, and then flows into the upper pump from the oil inlet 4a through the left second oil way 5d and the right second oil way 4d of the oil way. The new hydraulic oil in maintenance does not pass through the cylinder bodies of the two calipers, so that the old hydraulic oil still remains in the two calipers, and the hydraulic oil cannot be thoroughly replaced.
