Description

Technical Field

[0001] The utility model relates to the technical field of GKD2 locomotive brake devices, in particular to an adjustable brake cross-bracing bar for a GKD2 locomotive. Background Art

[0002] The GKD2 locomotive has a problem of left and right eccentric wear of the brake shoe in actual use. The GKD2 locomotive's basic brake device cross bar is made of a round steel with a total length of 1710mm, and the length cannot be adjusted. Figure 2 As shown in the figure, if the amount of the basic brake device pin sleeve is slightly larger, the vertical rod 1 and the brake shoe support will tilt, causing the brake shoe 3 to wear eccentrically to the left and right. The direct harm of eccentric wear is that the contact area between the brake shoe and the wheel 4 tread becomes smaller, resulting in reduced friction and longer braking distance, thus endangering driving safety. At the same time, eccentric wear of the brake shoe will also increase the consumption of the brake shoe and shorten the service life of the brake shoe. Utility Model Content
