Abstract
A railway vehicle brake block holder (11) for a brake unit (1) with brake block hangers (9) pivotally attached to a fixed part (8) of the unit and to the brake block holder. In order primarily to obtain a very compact design the brake block hangers (9) are pivotally attached to the lower part of the brake block holder (11) and to brackets (8) on the unit constituting a lateral guiding for the holder. The two hangers (9) together with two inserts (13) are held together as a strong yoke by a screw (12). Means (14-18, 22, 23) are provided for obtaining a self-adjusting force transmitting connection between the only axially movable brake unit push rod (3) and the brake block holder (11).
Claims9
A railway vehicle brake block assembly with means for its suspension including brake block hanger means pivotally attached to a fixed part and to a brake block holder, and with means for connection to a brake force applying such rod, comprising in combination,
- said brake block hanger means including structure extending from its pivotal attachment position on the fixed part considerably past the center of the brake block holder to a single pivoted position on the brake block holder,
- and means engaging said push rod with the brake block holder near the center thereof in a position intermediate the pivot positions of the hanger means.
A railway vehicle brake block assembly comprising in combination, a brake unit including means for reciprocally moving a push rod in response to braking forces, a brake block holder for reciprocal movement by said push rod, brake block hanger means pivoted from a fixed part on the vehicle to a single pivoted position on the brake block holder positioned near one end of the brake block holder, and means coupling the push rod to the brake block hanger for reciprocal movement thereof at a position near the center thereof between the two said pivoted positions.
