FREIGHT CAR BOGIE BRAKE LEVER TRANSMISSION Russian patent published in 2019 - IPC B61H13/20 B61H15/00 B61H1/00 

FIELD: machine building.

SUBSTANCE: invention relates to braking systems of freight car bogies that do not have direct adjustment of brake shoes uniform removal. Freight car bogie brake lever transmission includes triangles (1), shoes connected with triangles (1) and side frame via suspensions, levers (5) connected in vertical plane of connection of shoes with triangles (1) and tightening, device for uniform removal of brake shoes. Each of levers (5) is made bent and is located with convexity towards the middle of bogie, and the spacer is connected to the rod with two holes, the distance between which is equal to the distance of the part of lever (5) located between its connection with the spacer and the puff, thus forming a parallelogram of connection of lever (5) with the spacer. Lever is made with one bend in vertical bogie longitudinal plane.

EFFECT: reduction of costs due to reduced wear of brake pads and labor input on their replacement, as well as elimination of de-harmonization of car brake connection.
