Problems solved by technology
The structure of the three-point installation is scattered, the space required is large, and the installation is inconvenient; the structure of the four-point installation generally bears the braking force through the lever, and there is no parallel mechanism for the brake pad. When the vehicle brakes, the gap between the brake pad and the brake disc prone to eccentric wear

The embodiment of the present invention relates to a lever hanger for a brake caliper unit, wherein the lever hanger includes a hanger, two booms, two brake pad holders, two brake caliper arms, and two rotating shafts and the connecting frame; the first end of the boom is connected with the hanger, and the second end is connected with the brake pad support; the brake cylinder connection end of each brake caliper arm is connected with the power output part of the brake cylinder; the brake pads The connecting end of the support is connected with the brake pad support; the connecting frame is connected with the fixed part of the rotating shaft of the brake caliper arm through the rotating shaft; the two connecting ends of the brake cylinder are driven by the driving force output by the power output part of the brake cylinder The opposite rotation or opposite rotation around their respective rotating shafts, and at the same time, the connecting end of the brake pad holder exerts a driving force on the brake pad holder in the tangential direction of the rotation, so that the two brake pad holders move toward each other or move backward under the driving force, so that The brake pads provided on the pad holders are in contact with or separated from the brake discs provided between the two pad holders.
Description
technical field [0001] The invention relates to the technical field of brake devices for rail locomotives, in particular to a lever hanger for a brake caliper unit. Background technique [0002] The brake caliper unit is the actuator of the rail vehicle braking system and usually includes a brake cylinder and a lever hanger. The lever hanger can convert the thrust provided by the brake cylinder to the brake pad holder through the lever function, and the friction between the brake pad installed on the brake pad holder and the brake disc is driven by the brake pad holder, so as to realize the braking of the vehicle . [0003] At present, the connection methods between the brake caliper unit and the bogie used in locomotives, bullet trains, high-speed passenger cars, urban rail vehicles, etc. are mainly divided into three-point installation and four-point installation. The structure of the three-point installation is scattered, the space required is large, and the installatio...
