Description

Technical Field

[0001] This utility model relates to the field of brake shoe technology, and in particular to a synthetic brake shoe for subway use. Background Technology

[0002] Synthetic brake shoes for subways are a high-performance friction material specifically designed for subway train braking systems. They are made by compounding various organic and inorganic materials (such as resin, rubber, fiber, metal powder, and friction modifiers) under high temperature and pressure, and have excellent wear resistance, heat resistance, stable coefficient of friction, and environmental protection characteristics.

[0003] Currently, the friction element in synthetic brake shoes used in subways is prone to cracking, and there is also a risk of the friction element detaching from the back iron. Therefore, it is urgent to design a new type of synthetic brake shoe for subways to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a synthetic brake shoe for subways, so as to solve the problems of easy breakage of the friction body and the risk of separation between the friction body and the back iron in the existing synthetic brake shoes for subways.

[0005] To solve the above-mentioned technical problems, this utility model provides a synthetic brake shoe for subways, including a friction body. The friction body has several evenly distributed material-grabbing holes at both ends on one side, and two back irons are fixed at both ends on the other side.

[0006] Both ends of one side of the friction body are equipped with gripping claw mechanisms.

[0007] As a further improvement to the above technical solution:

[0008] Furthermore, the gripping claw mechanism includes a first gripping claw, a second gripping claw, and a third gripping claw arranged in sequence, all of which are fixed to the friction body.

[0009] Furthermore, two welding points are provided on one side of the friction body.

[0010] Furthermore, both of the back irons are equipped with positioning feet.

[0011] Furthermore, both of the back iron surfaces are galvanized.

[0012] In the synthetic brake shoe for subway provided by this utility model, the friction body has several evenly distributed gripping holes at both ends on one side, and two back irons are fixed at both ends on the other side. The friction body is provided with gripping claw mechanism at both ends on one side. When using the synthetic brake shoe for subway, the friction body is not easy to break, and there is no risk of the friction body detaching from the back iron. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] This utility model provides a synthetic brake shoe for subway use, the structure of which is as follows: Figures 1-2 As shown, the device includes a friction body 1. Each end of one side of the friction body 1 has several evenly distributed gripping holes 2, and each end of the other side has two back irons 3 fixed to it. Both ends of one side of the friction body 1 are equipped with gripping claw mechanisms. Using synthetic brake shoes for subways, the friction body 1 is less prone to breakage, and there is no risk of the friction body 1 detaching from the back irons 3.

[0019] Furthermore, the gripping claw mechanism includes a first gripping claw 4, a second gripping claw 5, and a third gripping claw 6 arranged in sequence, all of which are fixed on the friction body 1.

[0020] Furthermore, two welding points 7 are provided on one side of the friction body 1.

[0021] Furthermore, the surfaces of the two back irons are galvanized.

[0022] Beneficial effects

[0023] The back iron 3 is galvanized, making it less prone to rust. Furthermore, the addition of a gripping hole 2, a first gripping claw 4, a second gripping claw 5, and a third gripping claw 6 to the friction body 1 results in a higher degree of bonding between the back iron 3 and the friction body 1, thus reducing the risk of the friction body 1 breaking or detaching from the back iron 3.

[0024] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
