AI Technical Summary

Technical Problem

Existing technologies cannot effectively verify the durability of lever-type brake calipers, especially in extreme environments where wear conditions cannot be simulated. This makes it impossible to determine whether the wear stroke of the friction pads and spacers is sufficient, and internal leakage cannot be detected.

Method used

Design a durability testing device that includes a test base, a load module, a braking module, a power module, and a high and low temperature test chamber. By simulating high temperature, low temperature, or normal temperature environments, the device monitors the wear amount of the braking stroke using a wear gauge and a transmission pointer. Combined with the pressure value provided by the power module system, a cyclic test is conducted to count the wear amount.

Benefits of technology

It enables durability testing of lever-type brake calipers under extreme environments, reduces labor costs, shortens development cycles, accurately determines wear and internal leakage, and improves the efficiency of brake caliper reliability verification.

Abstract

The application belongs to the technical field of brake pump testing, and particularly relates to a durability testing device for a lever type brake master cylinder and a testing method thereof. The device comprises a test base, a load module, a brake module, a power module system and a high-low temperature test box. The load module comprises a brake cylinder seat, a wear gauge dial and a first pressure gauge. The brake module comprises a lever type brake master cylinder, a pin shaft, a top rod and a transmission pointer. The power module system is used for providing the lever type brake master cylinder with oil liquid with a required pressure value, simulating the working process of the lever type brake master cylinder and circulating the test times. The transmission pointer is used for indicating the scale value of the wear gauge dial, so as to obtain the brake stroke wear. Therefore, the application simulates high temperature, low temperature or normal temperature environment, performs the durability test of the brake master cylinder, avoids the test verification through the vehicle, facilitates the verification of the brake times and brake strength, can verify the reliability of the parts in advance, and reduces the project development risk.
