UA56459U - Cushioning unit for coupling device - Google Patents

Abstract

A cushioning unit for a coupling device comprises a body tightened by a bolt, inside which there are located a spring back-and-support mechanism consisting of outer and inner springs, a pressure element and friction wedges. The body is made-cast as a sleeve closed from one side, and on the inner surface of neck it has faces to match with the friction wedges.

Description

with a bolt, a multi-faceted body, inside which the entire set of essential features is placed spring return-support mechanism of the proposed solution in relation to the absorbing system, consisting of an external spring and an internal apparatus for railway rolling stock without a spring, a pressure cone and friction ensures the achievement of a technical result. in which anti-friction inserts are installed, which The further essence of the proposed utility act as a solid lubricant for the walls of the housing, with the model it is explained together with the illustrative material that the walls of the housing have different thicknesses, and the plot on which it is shown: the thickness of the solid lubricant is greater than on the side of the walls of the body Fig. 1 - the proposed absorbent device has a smaller thickness and, conversely, a smaller longitudinal section on the side of the walls; thicker casing | see patent of the Russian Fig. 2 - a top view of the proposed apa-

The main disadvantage of the known apparatus is the integrally cast body in the form of a bushing 1, which, on the one hand, is the risk of destruction of its body under the action of the bottom 2, and on the other hand, accordingly, maximum longitudinal forces that can neck C with faces 4 on the inner surface To occur during the collision of wagons. There is a high probability of spring damage to the housing cavity 1 due to the unevenness of the back-support mechanism in the form of an external load on its surface due to spring 5 and internal spring b, each of which has a different wall thickness. one end is attached to the inner surface

The next shortcoming of the well-known device of the auger 2, and the other rests on the frictional wedges of the nay, is the multifaceted shape of the body, which is connected to the pressure cone 8. nut 10. pulling its surface. In this case, all the force The proposed absorbing apparatus works of the arising stresses is concentrated on the sti- as follows. of faces, and the body can tear into pieces, in The compressive (impact) force is transferred to, as a result, the unabsorbed force of the impact on the pressure cone 8 protruding from the edges of the body 1 will inevitably disable the clutch Under the action of the specified force, the pressure cone 8 between wagons the zoom with friction wedges 7 starts to move

Also a disadvantage is the technological complexity of hollowing out the housing 1, while compressing the springs 5 and preparing the well-known absorbing device 6, which absorb (accumulate) the energy of the impact due to the need to clearly determine the elastic deformation. With the termination of the effect of the thickness of the walls in different parts of the body from the shock load, the springs are restored by the following compensation of this difference with the help of their shape, as a result of which the device turns anti-friction tabs. to the starting position.

The basis of a useful model is the task of the proposed absorbent apparatus, and increasing the reliability of the absorbent operation is prepared, for example, according to the drawings of the apparatus with the simultaneous simplification of its design and manufacturing technology at the expense of optimization, proven in practice, does not contain any erosion of the strength and geometric parameters of bodies or materials, which would be impossible to reproduce by spatially changing its design. dig at the current stage of development of science and technology,

The solution to the given problem is achieved by, in particular, in the production of shock-absorbing apparatus, which contains a tightened structure, and therefore is acceptable for industrial bolt housing, inside which the pressure is placed. , which consists of well-known analogues due to the proposed construction of an external spring and an internal spring, active simplifications and changes, which confirms the possible pressure element and friction wedges, according to the ability to achieve the technical result of the object, the body is made of solid cast in the complaint that is declared. In the known sources, the scientific review of the sleeve, which is closed on one side by the bottom, and technical and other information is not found, is absorbed. tyu of essential features, therefore the proposed technical one

The presence of a one-piece body of the proposal is considered to be such that a configuration with the same wall thickness can receive legal protection. contributes to the even distribution of shock and thrust loads on all parts and nodes of the absorber. metric parameters and faces on the inner

The specified differences in the body parts increase the manufacturability of the joint assembly, provide an improvement in the consumer elements in the proposed device without the characteristics of the device with a simultaneous simplification of the design, and also improve the functionality of its design and reduce the cost. functionality of friction wedges. At the same time, no known absorbent device can be localized exclusively in the neck of the case and be distinguished by the specified differences, since it does not have a conan on its inner surface, and therefore their presence in the composition of the entire set of proposed structures, unlike prototype, not technological and constructive features that would ensure dangerous stress concentrations.

Among the proposed main technical advantages - simplification of the design due to the absence of a technical solution, in comparison with the prototype - anti-friction inserts in friction wedges; pom, the following can be attributed: - improvement of the functioning of the pressure device - ensuring uniform distribution of the device without reducing the strength characteristics of impact and traction loads on all parts and devices - due to the edges on the inner surface of the neck of the absorbing device due to the use of the case; in the construction of a one-piece body with the same - simplification of the manufacturing technology by absorbing the thickness of the walls; equipment, as well as facilitating scheduled inspection and repair procedures for the same reason. 7 and 6.
