Description

Technical Field

[0001] The utility model belongs to the technical field of center plate wear plates, and specifically relates to a lightweight, high-strength and long-life center plate wear plate. Background Art

[0002] The center plate wear plate is one of the key components in the railway vehicle bogie. Its main function is to reduce the wear between center plates, improve the running stability and safety of the vehicle. The center plate wear plate (also known as the center plate gasket) is usually installed in the middle of the bolster of the freight car bogie and works with the center plate to reduce the direct friction and wear between the center plates, providing a layer of buffering and protection. The center plate wear plate can stabilize the rotational resistance moment value of the car body relative to the bogie, extend the service life of the center plate, and reduce the maintenance cost. However, there are still the following defects:

[0003] Since both sides of the center plate wear plate are in contact with two center plates, the friction received by the center plate wear plate is large, resulting in serious wear of the center plate wear plate, so that the whole center plate wear plate needs to be replaced frequently, and the cost is relatively high. Summary of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a lightweight, high-strength and long-life center plate wear plate, which effectively solves the problem of high cost caused by frequent replacement of the whole center plate wear plate.

[0005] To achieve the above object, the utility model provides the following technical solution: A lightweight, high-strength and long-life center plate wear plate, including a wear plate body. The wear plate body is provided with an upper end surface and a lower end surface. An installation groove is opened on the lower end surface, and the inner diameter of the installation groove is the same as the inner diameter of the wear plate body. Contact friction members are installed on one side of the upper end surface far away from the installation groove and inside the installation groove.

The positioning grooves correspond to each other in pairs, and the positioning blocks on the friction disc are inserted into the positioning grooves.

[0009] Preferably, the interior of the wear plate body is provided with activity grooves at equal angles. Four rod grooves are opened at one end of the activity grooves close to the corresponding two positioning grooves.

A contact friction member 5 is installed on one side of the upper end face 2 away from the installation groove 4 and inside the installation groove 4;

[0025] The contact friction member 5 includes two friction discs 501. One of the friction discs 501 is in close contact with the surface of the upper end face 2, and the other friction disc 501 is installed inside the installation groove 4. A clamping and fixing assembly 6 is installed on the wear plate body 1. The clamping and fixing assembly 6 is used to fix the friction disc 501. Positioning blocks 502 are evenly installed at equal angles on the side of the two friction discs 501 close to each other, and card slots 503 are symmetrically opened on the positioning blocks 502.

[0026] The snap - fixing component 6 includes positioning grooves 601 respectively and equiangularly opened on the upper end surface 2 and the inner wall of the mounting groove 4. The positioning grooves 601 correspond to each other in pairs. The positioning blocks 502 on the friction disc 501 are inserted into the interior of the positioning grooves 601. The interior of the wear - resistant disc body 1 is equiangularly provided with movable grooves 602. Four rod grooves 603 are opened at one end of the movable groove 602 close to the corresponding two positioning grooves 601. The four rod grooves 603 respectively penetrate through these two positioning grooves 601, and the four rod grooves 603 respectively correspond to the card slots 503 on the corresponding two positioning blocks 502. An activity plate 607 is movably installed inside the movable groove 602. Four clamping rods 608 are installed on one side of the activity plate 607. The four clamping rods 608 respectively pass through the four rod grooves 603 and are clamped into the card slots 503. On the other side of the activity plate 607, springs 609 are symmetrically installed. One end of the spring 609 is fixedly connected to the inner wall of the end of the movable groove 602 away from the positioning groove 601. A screw groove 604 is opened at the end of the movable groove 602 away from the positioning groove 601. End grooves 605 are equiangularly opened on the outer wall of the wear - resistant disc body 1. The screw groove 604 is communicated with the end groove 605. A bolt 606 is threadedly installed inside the screw groove 604. The tail of the bolt 606 contacts the activity plate 607, and the head of the bolt 606 is received inside the end groove 605. Friction discs 501 are installed on the surface of the upper end surface 2 of the wear - resistant disc body 1 and inside the mounting groove 4. The friction discs 501 are in contact with the center disc, reducing the wear of the wear - resistant disc body 1 and extending the service life of the wear - resistant disc body 1. By screwing the bolt 606, the clamping rods 608 on the activity plate 607 are pushed into the card slots 503 on the positioning blocks 502, facilitating the disassembly, installation and replacement of the friction disc 501, facilitating the replacement of the worn friction disc 501, and improving the protection of the wear - resistant disc body 1.

[0027] A buffer sleeve 7 is sleeved outside the wear - resistant disc body 1. The material of the buffer sleeve 7 is rubber. The buffer sleeve 7 limits the head of the bolt 606. A buffer sleeve 7 is sleeved outside the wear - resistant disc body 1. The buffer sleeve 7 is closely attached to the outer wall of the wear - resistant disc body 1 under the action of its own elastic force, and then can limit the head of the bolt 606, reducing the loosening of the bolt 606, improving the clamping stability of the clamping rod 608 and the card slot 503, improving the fixing effect of the friction disc 501. At the same time, the buffer sleeve 7 can buffer the impact force, thereby improving the protection effect on the wear - resistant disc body 1 and further extending the service life of the wear - resistant disc body 1.

[0028] Working principle: During operation, first place the friction disc 501 on the upper end face 2 and the inner side of the installation groove 4, so that the positioning block 502 on the friction disc 501 is inserted into the positioning groove 601. Subsequently, screw the bolt 606 into each screw groove 604, so that the bolt 606 continuously enters the movable groove 602, pushing the movable plate 607 towards the positioning groove 601, and making the clamping rod 608 pass through the rod groove 603 and snap into the clamping groove 503, thereby clamping and fixing the two friction discs 501, facilitating the installation of the friction disc 501. The two friction discs 501 are respectively in contact with the upper center plate and the lower center plate, reducing the wear of the wear plate body 1 itself and extending the service life.

[0029] After installation, sleeved with a buffer sleeve 7 on the outside of the wear plate body 1, the buffer sleeve 7 is closely attached to the outer wall of the wear plate body 1 under the action of its own elastic force, thereby limiting the head of the bolt 606 to prevent the bolt 606 from loosening, improving the fixing effect on the friction disc 501, and at the same time, the buffer sleeve 7 can play a buffer protection role for the wear plate body 1.
