Technical field
The present invention relates to train bogie, particularly low floor tramway train bogie truck.
Background technology
The modern tramway train of 100% low floor adopts without bow and is subject to the sophisticated technologies such as stream, super capacitor, and floor is apart from approximately 38 centimetres of rail levels, and without platform, maximum freight volume is 6 to 8 times of bus.Vehicle can adopt storage battery and super capacitor parallel hybrid power, provides all fronts without net-fault scheme, and hill climbing ability is strong, approximately 20 meters of minimum turning radius, city existing road gets final product laying-out, and environmental protection, low noise are one of state-of-the-art Traffic Systems in the world today.
The modern tramway train of 100% low floor has comprised bogie truck and car body, for the modern tramway train of 100% low floor, realize the object of low floor, and very important of the design of bogie truck, also exists many different structures for different requirements.As at application number being 201010520644.5 open days is to disclose a kind of 100% low-floor light rail vehicle mechanism of independent wheel power truck in the patent documentation on February 23rd, 2011, and specifically disclose it and comprise framework, axle bridge composition, primary spring, secondary spring, two is vertical, lateral damper, duplex pull rod trailer coupling, elastic suspension motor longitudinal driving mechanism, hydraulic brake unit, truck side sill is outwardly cantilevered, two minor axises are supported and are connected respectively separately an elastic wheel by bearing unit, axletree is made up of two minor axises, two wheels of bogie truck the same side are fixed on motor driving shaft, motor connects with two gears case, brake system and traction electric machine become one, and four two is that vertical damper is located on four jiaos of framework, two is the end positions that lateral vibration absorbing device is located at framework, parallel double-draw rod traction system is located at the inner side of framework.Said structure adopts high-intensity welding framework and independent axle bridge composition, primary spring rational in infrastructure and secondary spring, two of the best is vertical and lateral damper, and parallel double-draw rod draw gear and the elastic suspension motor of traction in adopting longitudinally drive, adopt the hydraulic brake unit integrated with traction electric machine, really realized car body 100% low floor requirement.What this bogie truck adopted is the technology of longitudinal coupled drive, only have the mechanism of independent wheel of a side to there is driving power, and opposite side belongs to passive rotation, be difficult to ensure the mechanism of independent wheel synchronous rotary of card both sides, therefore, train is in operation and can be difficult to ensure because of propulsive effort overbalance the stationarity of train operation, is difficult to ensure the centering of wheels on straight line, easily occurs the phenomenon of flange wear; In addition, although said structure has adopted minor axis mechanism of independent wheel structure, and adopt axle bridge composition, but axle bridge composition is positioned at minor axis below in the vertical direction substantially, when light rail car is during along curve motion, axle bridge composition, with mechanism of independent wheel, angle occurs substantially simultaneously to be changed, and the guidance capability of mechanism of independent wheel is poor, bogie truck turn to freedom not good enough, the noise of operation is bigger than normal.
Also there is in the prior art the bogie truck that two side wheels are connected by axle, as being that 201310265642.X discloses 100% low-floor light rail vehicle rigid wheel to single motor coaxle two-wheel drive mechanism in the patent documentation on November 6th, 2013 at application number, this driver train is by framework, wheel to and actuating device composition, wheel is to being made up of wheel and the S. A. being connected on the wheel of both sides, actuating device drives S. A. rotation, thereby driven wheel is to rotation, the wheel of this structure and rotating shaft coaxle, when light rail car is during along curve motion, the guidance capability of mechanism of independent wheel is poor, bogie truck turn to freedom not good enough, the noise of operation is bigger than normal.Similar structure is also disclosed in the patent documentation that is US20100132586A1 at document number.
Be within 200710007908.5 open days, to be to disclose a kind of axletree for low clearance chassis rail vehicle in the patent documentation on August 8th, 2007 at application number, suspension gear and guideway vehicle, and specifically disclose this guideway vehicle and comprise car body and bogie truck, wherein bogie truck comprises framework and is suspended on the wheel assembly at framework two ends, described wheel assembly is mainly by axle box, mechanism of independent wheel, cross member composition, axle box is connected on framework by single stage suspension, mechanism of independent wheel is installed in the axial direction, cross member is connected between two axle boxes of left and right, although this bogie truck has adopted mechanism of independent wheel structure, and adopt cross member, but cross member is positioned at minor axis below in the vertical direction substantially, when light rail car is during along curve motion, axle bridge composition, with mechanism of independent wheel, angle occurs substantially simultaneously to be changed, the guidance capability of mechanism of independent wheel is poor, bogie truck turn to freedom not good enough, the noise of operation is bigger than normal.In document number is the patent documentation of EP2551166A1, US8381659B2, US20130333590A1, similar structure is also disclosed, the basic structure of these bogie trucks is to adopt longitudinal coupled drive, connect axle box by the cross member that is substantially positioned at mechanism of independent wheel below, when light rail car is during along curve motion, axle bridge composition, with mechanism of independent wheel, angle occurs substantially simultaneously to be changed, the guidance capability of mechanism of independent wheel is poor, bogie truck turn to freedom not good enough, the noise of operation is bigger than normal.
Be the bogie truck that discloses a kind of transverse coupling transmission during 201320379293.X discloses the patent documentation that day is on January 1st, 2014 at application number, this bogie truck is mainly by framework, it is right to take turns, transverse coupling mechanism and driver train composition, it is right that wheel is connected to form described wheel by transmission shaft, transverse coupling mechanism comprises transmission shaft, driver train drives the rotation of wheel of a side, and simultaneously by the rotation of wheel of transverse coupling mechanism drive opposite side, the wheel of this structure and rotating shaft coaxle, when light rail car is during along curve motion, the guidance capability of mechanism of independent wheel is poor, bogie truck turn to freedom not good enough, the noise of operation is bigger than normal.And if S. A. is simply directly removed, the wheel of both sides will separate, simultaneously gear case and axle box also can separate, bogie truck cannot be worked normally.
In addition, in existing 100% low floor train bogie, be also provided with air bellow, air bellow is a kind ofly to utilize the elastic force producing after air compressing and the form of springs of making is mainly used in locomotive shock mitigation system.Energy chamber on engine truck is to be generally directly installed on framework at present, makes locomotive main will rely on air bellow as shock mitigation system, and such shock mitigation system stability is inadequate; In addition, each energy chamber is by independent tracheae air feed, has increased the complexity of energy chamber spring structure.
Have, after car body is installed on bogie truck, the height of car body is far longer than the height of bogie truck again, and therefore, train, in operational process, easily occurs the phenomenon of lateral deviation, makes the fluctuation of service of train.
