Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings. However, it should be understood that the accompanying drawings are provided only for better understanding of the present invention, and they should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "first", "second" and so on are only used for the purpose of description, and should not be understood as indicating or implying relative importance.

[0013] Such as Figure 1~3 As shown, the elastic brake shoe pin ring provided by the present invention includes an annular body 1 bent by spring steel and has an opening. One end of the opening of the annular body 1 spirally extends upward along the annular body 1 to set a first pressing section 2. The other end of the opening of the ring body 1 spirally extends downward along the ring body 1 to set the second pressing section 3, and the o...

Abstract

The invention relates to an elastic brake-shoe pin ring. The pin ring is characterized in that the elastic brake-shoe pin ring comprises an annular body with an opening, a pressing segment, a guide segment and preset openings; the annular body is formed by bending spring steel; a first pressing segment is arranged at one end of the opening of the annular body along the annular body in an upward spiral extension mode, and a first guide segment is arranged at the outer end of the first pressing segment along the circumference in an upward and inclined extension mode; a second pressing segment isarranged at the other end of the opening of the annular body along the annular body in a downward and spiral extension mode, and a second guide segment is arranged at the outer end of the second pressing segment along the circumference in a downward and inclined extension mode; the preset openings are formed between the first guide segment and the annular body and between the second guide segmentand the annular body. The elastic brake-shoe pin ring can be widely applied to braking of railway vehicles.

Description

technical field [0001] The invention relates to an elastic brake shoe pin ring suitable for railway vehicles, and relates to the technical field of railway vehicle braking. Background technique [0002] The railway vehicles in the prior art use brake shoes for braking, usually the brake shoes are installed on the brake shoe holder, and the brake shoe pin is inserted between the brake shoe and the brake shoe holder and fixed with the brake shoe holder, in order to prevent the brake from being damaged during use. The shoe plug accidentally escapes from the brake shoe support, and a brake shoe pin ring is arranged in the mounting hole at the bottom of the brake shoe plug. [0003] At present, the railway wagons use F-grade galvanized low-carbon steel wire brake shoe pin rings in accordance with TB / T34-1999. This kind of brake shoe pin rings has problems such as inconvenient assembly and disassembly, insufficient elasticity and easy loss during use. Contents of the invention ...
