Abstract
A friction cement combined buffer is provided, which is a train coupler buffer for solving the problem of prior art, such as poor capacity and poor effect of energy absorption. The combined buffer comprises a cement elastic body (1), an outer spring (2), a corner spring (3), a shell (4), and a press plate means (5). The cement elastic body (1), the outer spring (2), the corner spring (3) and the press plate means (5) are all arranged in the inner cavity of the shell (41). The cement elastic body consists of a cylinder (6), a piston (7), a sealing device (8), elastic cement (9) and a slide sleeve (10). The piston (7) is connected with a piston rod (71) and arranged together with the elastic cement (9) in the inner cavity (61) of the cylinder, and then is threadedly connected with the cylinder (6) into a sealed body via a cylinder cover (81) of the sealing device (8). The sealed body is further arranged inside the slide sleeve (10). The utility model is mainly used in heavy-duty trucks or shunting locomotives.
Description
Technical field
The utility model relates to a kind of used for rolling stock coupler draft gear, and what filled clay fuse inside wherein is a kind of compressible semifluid High molecular material.
Background technology
Along with China railways develops to " heavy duty, quick, safety " direction, the load-carrying of rolling stock constantly increases, and running velocity improves constantly, and therefore the longitudinal impact between rolling stock also increases, and the safety of rolling stock operation is had higher requirement.Coupler draft gear be guideway vehicle basic with one of important safety component; it can transmit the longitudinal traction power between vehicle; and relax the various longitudinal impact that rolling stock is produced in operation or when shunting; absorb impact energy; protection vehicle structure, assurance safe in operation, the performance that therefore improves constantly coupler draft gear is one of approach that improves rolling stock riding quality and operating efficiency.
Existing principal mode buffer capacity is low, poor reliability, and performance is big with temperature Change, and especially low-temperature properties is bad, is restricting railway transportation and is developing to high speed and heavily loaded direction.Under existing installing space size, be difficult to satisfy the operation requirement as energy disperser MT-2, the MT-3 of common employing, ST series etc., occurred easily killing the phenomenon that produces rigid shock, caused riding quality to descend and service expenditure sharply increases.
The content of utility model
Technical problem to be solved in the utility model is the off-capacity that overcomes the train coupler energy disperser, improve the energy-absorbing effect of coupler draft gear, a kind of suitable hitch size is provided, capacity increases and the high coupler draft gear of capacity absorptivity, this bumper property is stable, automatically reply, noise-less pollution, quick and easy for installation.
To achieve these goals, the utility model is achieved through the following technical solutions: friction clay combined buffer, by clay elastic body (1), outer coil spring (2), angle spring (3), housing (4), pressure plate structure (5) is formed, and clay elastic body (1) is contained in the housing inner chamber (41) with outer coil spring (2), angle spring (3), pressure plate structure (5).Wherein clay elastic body (1) is by cylinder body (6), piston (7), sealing arrangement (8), elastic cement (9) and sliding sleeve (10) are formed, elastic cement (9) is a kind of high viscosity, compressible semifluid High molecular material, other element is all cylindrical, piston (7) is connected with piston rod (71), and place inner chamber of cylinder block (61) with elastic cement (9), cylinder cap (81) by sealing arrangement (8) are housed and cylinder body (6) are spirally connected, and to become a sealing whole, and this integral body is packed in the sliding sleeve (10).
Owing to adopted technique scheme, the utlity model has following advantage and effect:
1. the utility model is applicable to the used for rolling stock coupler draft gear, particularly the heavy-duty vehicle coupler draft gear.
2. the utility model has adopted the clay elastic body, and its inner medium of filling is a kind of semifluid High molecular material, has high viscosity, compressibility, and special chemical inertness and good heat stability, the envelope area of load-displacement curve is big, and energy-absorbing effect is remarkable.
3. the utility model reasonable in design, volume is little, and is easy for installation, do not have aging and leakage phenomenon, long service life, maintenance and repair are simple and easy.
Description of drawings
Fig. 1 is the utility model structure collectivity cross-sectional schematic
Fig. 2 is the utility model working process scheme drawing
Among the figure: 1-clay elastic body, the outer coil spring of 2-, 3-angle spring, 4-housing, 41-housing inner chamber, 5-pressure plate structure, 6-cylinder body, 61-inner chamber of cylinder block, 7-piston, 71-piston rod, 8-sealing arrangement, 81-cylinder cap, 9-elastic cement, 10-sliding sleeve
The specific embodiment
By shown in Figure 1, friction clay combined buffer, mainly by clay elastic body 1, outer coil spring 2, angle spring 3, housing 4, pressure plate structure 5 is formed, and clay elastic body 1 is contained in the housing inner chamber 41 with outer coil spring 2, angle spring 3, pressure plate structure 5.Wherein clay elastic body 1 is by cylinder body 6, piston 7, sealing arrangement 8, elastic cement 9 and sliding sleeve 10 are formed, and elastic cement 9 is a kind of high viscosity, compressible semifluid High molecular material, and other element is all cylindrical, piston 7 is connected with piston rod 71, and place inner chamber of cylinder block 61 with elastic cement 9, and be spirally connected by cylinder cap 81 and the cylinder body 6 that sealing arrangement 8 is housed that to become a sealing whole, this integral body is packed in the sliding sleeve 10.
As shown in Figure 2, the high resiliency clay 9 of filling in the inner chamber of cylinder block 61 is made it keep certain precompressed compression to inner chamber of cylinder block 61 by compression in advance, when external load F power greater than the precompressed compression of clay elastic body 1 and outside coil spring 2, during the starting force sum of angle spring 3, outer coil spring 2, angle spring 3 is compressed, simultaneously the piston rod 71 of clay elastic body 1 moves to cylinder interior, elastic cement 9 gradually reduces, to produce dynamic counter-force F ', common balance external load F, piston 7 moved mutually with elastic cement 9 and produced friction this moment, impact kinetic energy is converted into heat energy dissipation, realizes energy-absorbing and buffering.After external load F cancelled, piston rod 71 automatically reverted to virgin state under the dynamic counter-force effect that elastic cement 9 produces, and spring also automatically resets.
Be provided with sealing arrangement 8 between the piston rod 71 of clay elastic body 1 and the cylinder cap 81, guaranteed the sealing of structure effectively.
