A high-speed rail brake test tool pliers

Abstract

The invention discloses a high-speed rail brake test tool clamp, which belongs to the technical field of disc brakes, and comprises a base. The guide pillars protrude to both sides perpendicular to the main board of the upper support frame, and are respectively slid and guided to connect with two pliers arms; the two pliers arms are arranged symmetrically, and the relative positions are locked by several fastening screws and nuts The front end of the pliers arm is provided with a hydraulic cylinder, and the working end of the hydraulic cylinder is detachably connected to the brake pad shoe seat, and the brake pad shoe seat is equipped with a brake pad. The high-speed rail brake test tool pliers of the present invention are convenient to be installed on the test stand, convenient to adjust, capable of installing brake pads of different specifications, and flexibly applicable to various test working conditions.

Description

technical field [0001] The invention relates to the technical field of disc brakes, in particular to a high-speed rail brake test tool pliers. Background technique [0002] At present, with the rapid development of my country's railway high-speed train industry, it has driven the rapid follow-up of accessories in the braking field of related equipment. Powder metallurgy brake pads are mainly used in disc brake devices in the high-speed rail field. The main material is metal powder and non-metal powder materials. Its high temperature resistance can reach 1000°C and it has excellent braking performance. When improving or testing the performance of friction materials, it is often necessary to conduct multiple bench tests. The brake calipers of each type of brake pads are often different. When different brake pads are used, the brake calipers often need to be replaced. However, for research institutes, brake manufacturers or brake pad manufacturers, it is often more expensive t...

AI Technical Summary

Problems solved by technology

The brake calipers of each type of brake pads are often different. When different brake pads are used, the brake calipers often need to be replaced. However, for research institutes, brake manufacturers or brake pad manufacturers, it is often more expensive to invest A lot of money, and the installation methods are different, and it needs to be equipped with a variety of installation tools to install on the brake stand

Moreover, under different braking test conditions, the specification, size and thickness of the brake disc often change, and the installation position may also change, which puts forward various requirements for the auxiliary installation tooling of the brake caliper.
