Abstract
The utility model provides a bogie for large railway maintenance machinery for increasing running speed of railways, which comprises a wheel-set driver, an axle wheel set, a frame, an axle box spring hanger fixed on the frame, a hydraulic dampener, and a center pin. The utility model is characterized in that on the side beam of the frame a second spring dampener and a locking cylinder are arranged. The second spring dampener comprises a supporting board, a spring seat on the supporting board and a dampening spring, a hydraulic dampener beside the dampening spring and a cross dampening drawbar. The utility model can efficiently buffer the impact and vibration from trains, improve smoothness and safety in trains at running, and can offset the vertical elasticity of the bogie at operation, so that the connection between a train body and the bogie will be rigid. While meeting a running speed of 120 km/h, the utility model will not influence the operation efficiency and accuracy. When not working, in addition to bearing and transferring vertical force, the utility model is also a main dampening member, can absorb efficiently vibration in trains through the helical spring connected with the hydraulic dampener, remove hi-frequency vibration, and improve vibration property and reduce noise.
Description
Technical field
The utility model provides a kind of two-axle bogie, and especially a kind of large-scale maintenance machinery diaxon speed-raising bogie belongs to railway large-scale maintenance machinery design and manufacturing technology field.
Background technology
Bogie is the running part of railway locomotive, its effect is to bear load and the motive power that car body transmits, take turns passing to rail by axletree, thereby guide whole locomotive to move along rail, guarantee voluntarily or connection hang under the running status all can be flexibly, safely along railway operation with pass through railroad curve.Existing bogie is mainly held driver, journal box spring hanger and hydraulic shock absorber, brake, framework and centrepin (also being tractor), dish that lateral stiffness is very big by wheel to be formed, and mainly bears vertical force by the centrepin that is connected with car body.There is following deficiency in this structure: 1, vertical natural bow very little (less than 50mm); 2, centrepin bears 80% of car body weight, and the lateral stiffness that dish holds is very big; More than 2 riding qualities that have a strong impact on this bogie.Therefore, be necessary prior art is improved.
Summary of the invention
The vertical natural bow that has the bogie existence now is very little in order to overcome, dish holds deficiencies such as lateral stiffness is big, and the utility model provides a kind of speed lifting bogie for large road maintenance machinery.
The utility model is realized by following technical proposal: a kind of speed lifting bogie for large road maintenance machinery, comprise wheel to driver, axletree wheel to, framework and be fixed on journal box spring hanger, hydraulic shock absorber and centrepin on the framework, it is characterized in that: the curb girder of framework is provided with by supporting plate, place spring base and damping spring thereof on the supporting plate, being positioned at second of other hydraulic shock absorber of damping spring and horizontal damping pull bar formation is spring vibration damper and locking cylinder.
Described spring base is made as upper and lower spring base, and wherein lower spring cup is fixed on the supporting plate, and upper spring seat is fixed on the car body, and the damping helical spring is housed between the upper and lower spring base, and the elasticity by spring cushions the shock and vibration from car body.
The upper end of described hydraulic shock absorber is installed on the upper spring seat, and the lower end is installed on the lower spring cup, and its effect is damped vibration, causes the vibration on spring top with the potential energy of avoiding coil spring to be subjected to discharging after the additional compression.
One end of described horizontal damping pull bar is fixed on the upper spring seat, the other end is arranged on the bogie frame, this horizontal damping pull bar and second is that spring vibration damper is formed lateral damper jointly, to prevent the excessive lateral displacement of vehicle frame and bogie, improves the running stability of complete machine.
The upper end of described locking cylinder is mounted on the car body, on the oil cylinder seat that the lower end is fixed on framework links to each other, by the vertical elasticity under its off setting operation state, makes to become between car body and the bogie to be rigidly connected, to satisfy the requirement of operation certainty of measurement.
The utility model compared with prior art has following advantage and effect: pass through such scheme, promptly on the basis of original one-level damping device that constitutes by journal box spring suspension and hydraulic shock absorber, set up again by spring base, spring, the secondary damping device that hydraulic shock absorber and horizontal damping pull bar constitute, make it to bear 100% of car body weight, and centrepin can vertically float, do not bear car body weight, only bear tractive force and lateral force, so, the vertical natural bow of this bogie is greater than 130mm, be equipped with the composite material frictional disk on upper spring seat again, can produce relative slip with the steel wearing plate on the car body, so the lateral stiffness of this bogie is less, can effectively cushion the shock and vibration of vehicle, improve vehicle smoothness and safety.And can when job state, offset the vertical elasticity of bogie, and make to become between car body and the bogie to be rigidly connected, when satisfying the 120km/h service requirement, do not influence operating efficiency and homework precision.Under non-operation situation, this device is except that bearing and transmit the vertical force, or main damping device, by helical spring and connect hydraulic shock absorber and can effectively absorb vibration in the vehicle operating, eliminate dither, improve vibration performance, reduce noise, in addition, can prevent the excessive lateral displacement of vehicle frame and bogie, improve the running stability of complete machine.
Description of drawings

Fig. 4 is for second being the enlarged drawing of spring vibration damper among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Wheel is installed in axletree wheel on 2 to driver 1, framework 3 is made of middle girder 16 and two curb girders 15, the hole 17 at middle girder 16 middle parts is used for the mounting center pin---and be tractor 8, two curb girders 15 of framework 3 are installed supporting plate 13, lower spring cup 12 is installed on the supporting plate 13, upper spring seat 7 is installed on the car body, damping helical spring 9 is installed between last lower spring cup, the upper end of hydraulic shock absorber 11 is fixed on the upper spring seat 7, the lower end is fixed on the lower spring cup 12, supporting plate 13 reaches goes up lower spring cup 7,12, helical spring 9, it is spring vibration damper that hydraulic shock absorber 11 constitutes second, laterally an end of damping pull bar 10 is fixed on the upper spring seat 7, the other end is fixed on the framework 3, this pull bar and second is that spring vibration damper constitutes lateral damper jointly, to prevent traversing the transfiniting between car body and the bogie, lay respectively at the locking cylinder 6 in two hydraulic shock absorber, 11 outsides, its upper end is fixed on the car body, the lower end is fixed on the oil cylinder seat 14 that links to each other with framework 3, lateral stiffness by spring guarantees the elasticity and the recovery of traversing, be the effect that the lateral displacement of spring vibration damper obtains traversing gear by second again, its effect be in horizontal partition the quality of bogie and car body, make car body not participate in crawling of bogie directly, thereby reduce the horizontal coherence power of car body and wheel to the lateral force of rail and the dynamic pressure when reducing curve negotiating, to improve locomotive at horizontal running stability.
