Describe
Nissin SUNRUN all-aluminium alloy forged caliper body, due to the internal closed system of the hydraulic disc brakes, so that the inside of the tubing is not easy to be dusty, reducing the frequency of maintenance. There is no more friction between the core and the line tube, making the inside of the line tube only liquid in the mechanical transmission, so the feel is very smooth. The four-piston design allows for a larger contact area between the brake pads and the discs, thus providing greater braking force. This makes the braking force more even and stable, and avoids problems such as brake pad bias wear and holding. This not only improves the reliability of the braking system, but also helps to improve riding safety. It can better achieve a balanced distribution of braking force between the front and rear wheels. It can transfer the cyclist's braking intention to the brakes more quickly.

How to optimize the brake system design of piston hydraulic disc brake set to reduce hydraulic resistance and pressure loss?

Optimizing the brake system design of a piston hydraulic disc brake set to reduce hydraulic resistance and pressure losses is a comprehensive task that requires consideration of many aspects. Here are some key steps and strategies:
Pipe design and connections:
Choose a pipe with a smooth inner wall to reduce friction loss of the fluid in the pipe.
Optimize the pipeline layout, minimize unnecessary bends and corners, and reduce pressure loss at fluid turns.
Ensure the tightness and sealing of pipeline connections to prevent pressure drops caused by leaks.
Selection of throttle valve and speed regulating components:
Select the appropriate type of throttle valve and arrange its position reasonably to reduce pressure loss at the throttle valve.
The speed control element should be as close as possible to the actuator to reduce the length and pressure loss of the hydraulic circuit.
Optimization of control components and accessories:
Minimize the number of control components in the system to reduce system complexity and pressure losses.
Use high-quality joints and accessories to reduce leakage and pressure loss caused by quality problems in accessories.
Try using integrated components such as manifold blocks to reduce connection points in the system and reduce pressure losses.
Selection of working medium:
Use hydraulic oil of appropriate viscosity to balance fluid flow and pressure loss.
Ensure the cleanliness of the hydraulic oil and prevent impurities and pollutants from causing clogging and wear on the system, thereby affecting braking performance.
Simulation analysis and experimental verification:
Use hydraulic simulation software to model and analyze the braking system and predict the impact of different design parameters on hydraulic resistance and pressure loss.
The accuracy of the simulation results was verified through experiments, and the design was further optimized based on the experimental results.
maintain:
Perform regular maintenance and upkeep on the braking system, including replacing worn seals, cleaning pipes and fuel tanks, etc., to ensure normal operation of the system and low fluid resistance.
Establish a regular inspection and maintenance plan to detect and solve potential problems in a timely manner to prevent increased pressure loss due to system aging and wear.
Therefore, the brake system design of the piston hydraulic disc brake set needs to start from many aspects, comprehensively considering pipeline design, selection of throttle valves and speed control components, optimization of control components and accessories, selection of working media, and simulation Analysis etc. Experimental verification and many other factors. Through comprehensive optimization of these aspects, hydraulic resistance and pressure loss can be effectively reduced, and the performance and safety of the braking system can be improved. The brake system is designed to reduce hydraulic drag and pressure loss?
