The utility model arranges control pressurer system, controls the pressure of capsule at any time, improves the comfort property of guideway vehicle further, makes draw gear of the present utility model be applicable to the guideway vehicle of different automobile types simultaneously.
Embodiment 2
The present embodiment is substantially the same manner as Example 1, and institute's difference is: the rail vehicle truck draw gear in the present embodiment also comprises center key seat, and center key seat is socketed on center pin rotationally; Two traction Capsules group become to be connected with center key seat respectively, arrange in " Z " font.After installation, two traction capsule compositions 30 are positioned in same level.
Rail vehicle truck draw gear (is longitudinally installed) between framework 40 and the center pin 20 being installed on vehicle body bottom frame sleeper beam 10 lower surface, namely center pin 20 is fixed on the lower surface of vehicle body bottom frame sleeper beam 10 by bolt assembly, and two traction capsule compositions 30 are connected to the front-end and back-end of framework 40.The longitudinal rigidity of capsule 31 obtains by the inflation of setting pressure control system 50 and venting.In a pre-installation, capsule 31 is in pressure-less state, mounting center pin 20, after position suitable, from pressurized air step-down after reducing valve 55 of fluid source 52, be filled with capsule 31 by the valve 53 that is charged into opened, until capsule 31 expansion contact center pin 20, and keep the pressure of setting.When disassembly is desired, close and be charged into valve 53, open discharge-service valve 54, the pressurized air of capsule 31 is discharged rapidly simultaneously, and capsule 31 shrinks rear decomposition center pin 20.
During use, rail truck draw gear of the present utility model mode is as shown in Figure 1 arranged between the framework 40 of rail vehicle and vehicle body bottom frame sleeper beam 10.As shown in Figure 4, Q represents the bent characteristic curve of rigidity, when rail vehicle be at the uniform velocity travel time, when the longitudinal rigidity of capsule 31 is in the AI section that load-deflection curve Q is in as shown in Figure 4, effectively can isolate the small size displacement high-frequency vibration of framework 40, thus effectively suppress the longitudinal vibration that exists to the transmission of center pin 20 and car body 10; When being in traction or damped condition, center pin 20 relatively framework 40 produces larger longitudinal travel, and as shown in Figures 2 and 3, the traction capsule composition 30 being positioned at both sides before and after center pin 20 has one to be in compressive state.Mode of operation when braking for rail vehicle, braking force is transferred to vehicle body bottom frame sleeper beam 10 by wheel from framework 40, now, the traction capsule composition 30 be arranged on front side of center pin 20 is compressed effect, capsule 31 is squeezed, and capsule 31 is compressed, and interior pressure increases, thus raising longitudinal rigidity, when namely load-deflection curve Q is in IB section as shown in Figure 4.The traction capsule composition 31 be arranged on rear side of center pin 20 is stretched, and the pressure in capsule 31 reduces.In draw gear of the present utility model, traction rubber metal pad 32 has lower shear rigidity, so when car body occurs vertical or cross motion relative to truck frame, utilizes the traction rubber metal pad of low sheraing rigidity that traction capsule is formed and has good trackability.
The draw gear of the utility model by adopting, traction rubber metal pad and capsule is adopted to be formed by connecting, longitudinal force between vehicle body bottom frame sleeper beam and framework is nonlinear characteristic, while effective transmission longitudinal loading, avoid high-frequency vibration by draw gear to vehicle body bottom frame sleeper beam and car body transmission, improve travelling comfort.Structure of the present utility model is simple, and the longitudinal space required for installation is less, uses traction rubber metal pad, avoids damaging.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
