Description
Technical field
The present invention relates to track engineering vehicle technical fields, more particularly, to a kind of steering of electric transmission subway engineering vehicle
Frame traction device and its application.
Background technique
The EEF bogie of modern vehicle is most of all to use bogie form, and main function has: 1. bear each portion of vehicle frame or more
The weight divided；2. guaranteeing necessary stick together；3. making vehicle have good stationarity and stability when operation；4. guaranteeing that vehicle is smooth
Pass through curve；5. generating necessary brake force.And wherein traction device is as the critical component for connecting bogie and car body, mainly
Effect has: 1. adapt to bogie relative to the rotation of car body；2. transmitting tractive force and brake force.When vehicle operates normally, draw bar
The active force of transmitting is usually smaller, and the deflection of elastic panel nodes is also smaller.But when vehicle launch, braking or in some special works
When under condition, draw bar needs to transmit biggish impact forces, and the shock loading that elastic panel nodes are born is larger, elastic panel nodes
Deflection is also very big, and since rail vehicle starts, braking is very frequent, elastic panel nodes applying working condition is very severe.
The design of Draft gear of bogie is that bogie is enable preferably to cooperate body movement, and by tractive force and system
Power is transmitted to vehicle body, so that normal vehicle operation.It can be seen that the design of traction device has the running quality of vehicle
Very big influence, and traction device is relatively more by being limited when design, needs to follow the requirement of multiple conditions.It is overall and
The design of speech traction device needs to meet five requirements as far as possible: can steadily conveying capacity, bogie use up to the offset in vehicle body
Measure that small, towing point is low as far as possible, stiffness and strength is up to standard and structure cannot be too complicated.Wherein, vehicle runnability is influenced most heavy
Two wanted are big, and factor is exactly: structure type and arrangement, if thinking the runnability of raising vehicle, in fact seeks to as far as possible
Reduce axle weight transfer.And the axle weight transfer of vehicle just refers under traction working condition, produces the change of axle load.Generate this change
The main reason for change be due to acting on the outer wheels tractive force on vehicle and draw bar pull not in the same acting surface height,
This results in producing torque, and the load for having ultimately caused each axis of trailing or leading bogie is different.In addition, because in vehicle launch,
It is much larger when car load amount is than level road and descending and during going up a slope, so axis roller or axis transfer are in vehicle
The influence for starting and generating when going up a slope is bigger.
In the prior art, mainly have following technical scheme related to the present patent application:
The prior art was South car Zhuzhou Electric Locomotive Co in application on 09 30th, 2011, and in 2012 04
The moon 11 is open, the Chinese invention application " articulated bogie traction device " of Publication No. CN102407860A.The invention is public
A kind of articulated bogie traction device is opened, including the articulated mounting connecting with car body, two car bodies pass through articulated mounting, hinge
It connects on the same articulated bogie, articulated mounting includes the first support plate and the second support plate, and the first support plate has U-shaped
Slot, the second support plate have rubber spherical joint, and the second support plate is fixed on the U-type groove of the first support plate by rubber spherical joint
In；With articulated mounting cooperation be a kind of central pin traction device.The articulated bogie traction device that the invention provides, first
Support plate and the second support plate are connected from different car bodies respectively, to realize company of two car bodies on the same articulated bogie
It connects；Second support plate is fixed in the U-type groove of the first support plate by rubber spherical joint, due to the effect of rubber spherical joint, is protected
Certain transverse shifting can be occurred by demonstrate,proving between the second support plate and the first support plate, guarantee there is certain transverse direction between two car bodies
Mobile, deflection, torsion.
The traction device of description of the prior art is exclusively used in articulated bogie vehicle, with car body connecting portion point using hinged
One end of formula structure, drawing pull bar is connected with traction seat upper cover plate, and the other end is connected with bogie frame.The traction of the prior art
Pull rod installation site is lower, and the installation site of transverse hydraulic damper is too low, and it is low that this will lead to towing point, can not effectively transmit each
Traction and brake force and reduction axle weight transfer rate.Meanwhile the traction device of description of the prior art can not adapt to electric transmission subway rail
Road engineering truck use environment can not also be suitable for the bogie of urban light rail and state's iron main track vehicle, be unable to satisfy vehicle speed
Spend the requirement of 120km/h and smallest curve radius 145m.
