In order to achieve the above object, the present invention provides the following technical solutions:
the abrasion block for the left side of the railway vehicle comprises a steel back, wherein the steel back is of a rectangular structure, the upper end and the lower end of the two side walls of the steel back extend outwards to form a limiting table, the bottom of the steel back is sunken inwards to form a friction groove, and a friction plate is arranged in the friction groove.
Preferably, the steel back is made of Q235B steel, and the friction plate is made of polymer composite.
Preferably, the steel backing and the friction plate are connected through a bonding agent by high-temperature and high-pressure pressing.
Preferably, the bottom of the friction groove is a continuous wedge-shaped groove, the bottom of the friction plate is a continuous wedge-shaped block matched with the continuous wedge-shaped groove, and the top of the friction plate is located outside the friction groove.
Preferably, the wear block has a height of 43mm and a length of 107 mm.
Preferably, two sides of the limiting table extend out of the edges of two sides of the steel backing.
The utility model provides a railway vehicle wearing and tearing piece for left side has following beneficial effect:
the abrasion block consists of a steel backing and a friction plate made of polymer composite materials, a layer of adhesive is arranged between the steel backing and the polymer composite materials, and the abrasion block is formed by high-temperature and high-pressure pressing.

Example 1
The utility model provides a railway vehicle is wearing and tearing piece for left side specifically as shown in figure 1, including steel backing 1, steel backing 1 is the rectangle structure, both ends are outwards extended about steel backing 1 both sides wall and are formed spacing platform 2, and is specific, in this embodiment, the height of wearing and tearing piece is 43mm, and length is 107mm, realizes installing with the cooperation of current railway vehicle shock attenuation part, satisfies the installation size requirement with current part. The bottom of the steel backing 1 is inwards sunken to form a friction groove 3, and a friction plate 4 is arranged in the friction groove 3. The friction to which the shock absorbing member itself is subjected is reduced by providing the friction plate 4.
Further, in this embodiment, the steel backing 1 is made of Q235B steel, and the friction plate 4 is made of polymer composite. In the embodiment, the steel backing 1 and the friction plate 4 are connected through a binder by high-temperature and high-pressure pressing, and are formed through high-temperature and high-pressure pressing.
Further, in this embodiment, the bottom of the friction groove 3 is a continuous wedge-shaped groove, the bottom of the friction plate 4 is a continuous wedge-shaped block matched with the continuous wedge-shaped groove, the connection of the wedge-shaped structure is firmer, and the top of the friction plate 4 is located outside the friction groove 3.
Meanwhile, in order to meet the installation requirement, two sides of the limiting table 2 extend out of two side edges of the steel backing 1 in the embodiment.
The working principle of the abrasion block for the left side of the railway vehicle provided by the embodiment is that the abrasion block for the left side of the railway vehicle provided by the embodiment is used for preventing the left side of the vehicle from being abraded, the steel back is installed on the vehicle damping wedge body, the polymer composite material and the vehicle damping body rub against each other, and the abrasion block rubs back and forth in the running process of the vehicle to play a role in damping.
The above embodiments are only preferred embodiments of the present invention, the scope of protection of the present invention is not limited thereto, and any person skilled in the art can obviously obtain simple changes or equivalent replacements of the technical solutions within the technical scope of the present invention.
