Description

Technical Field

[0001] The utility model relates to an oil pressure caliper, in particular to an integrated oil pressure caliper with a single - cycle oil circuit. Background Art

[0002] As Figure 1 shown, the design of the integrated oil circuit adopts a non - one - way oil circuit structure.

Due to the residual air, it will have a negative impact on the braking feel, making the braking feel unstable and non - linear, thus affecting the driving safety and comfort. Therefore, improving the design of the integrated oil circuit to enhance its effect during evacuation and air bleeding is an important direction for improving the performance of the braking system.
