Embodiment Construction

[0060] see Figure 1 to Figure 3 . figure 1 It is a three-dimensional schematic diagram of the hydraulic assembly of the bicycle disclosed according to the first embodiment of the present invention. figure 2 for figure 1 The decomposition diagram. image 3 for figure 1 sectional schematic diagram.

[0061] In this embodiment, the hydraulic assembly 1 of the bicycle is used to accommodate a hydraulic oil (not shown in the figure). The hydraulic assembly 1 includes a casing 10 , a first piston 20 and a second piston 30 . In this embodiment, the hydraulic assembly 1 of the bicycle may further include a magnet 40 and an elastic member 50 .

[0062]The housing 10 has a hydraulic chamber 11 , an oil inlet passage 12 and an oil outlet passage 13 . In detail, the housing 10 includes a first shell portion 14 and a second shell portion 15 that are matched together. The hydraulic chamber 11 and the oil outlet channel 13 are located at the first shell part 14 , while the oil inle...

Abstract

A hydraulic assembly of a bicycle comprises a shell, a first piston and a second piston. The shell is provided with a hydraulic chamber, an oil inlet channel and an oil outlet channel, and the oil inlet channel and the oil outlet channel are connected with the hydraulic chamber; the first piston is movably positioned in the hydraulic chamber; the second piston is movably located in the hydraulic cavity and arranged on the first piston in a sleeving mode, the second piston is provided with a first end and a second end which are opposite, the outer diameter of the first end is larger than that of the second end, and the second end is far away from the oil inlet channel compared with the first end. When the distance of the first piston pushed by the hydraulic oil is smaller than a critical distance, the second piston is static relative to the shell, and the first piston moves relative to the second piston; when the distance of the first piston pushed by the hydraulic oil is larger than the critical distance, the first piston drives the second piston to move relative to the shell together.

Description

technical field [0001] The invention relates to a hydraulic component and a brake device, in particular to a hydraulic component of a bicycle and a brake device of the bicycle. Background technique [0002] In recent years, the bicycle market has been booming. Whether it is a high-end racing bicycle or a popular bicycle used as a means of transportation and entertainment, it is loved by consumers, prompting manufacturers to pay more attention to the user's demand for bicycle functions. The materials of the body and the functions of the equipment have been constantly improved, but the current bicycle still needs to be improved. [0003] In the case of bicycle brakes, the brake lever is used to actuate the brake calipers through hydraulic fluid, and the brake calipers are used to clamp the brake disc fixed to the wheel. When the brake handle is pressed, it will drive the piston in the brake handle to move and push the hydraulic oil, and then the hydraulic oil will actuate the...
