Abstract
A 100% low floor motor car independent-wheel bogie axle beam device comprises a cambered axle and a short axle, and is characterized in that a resilient wheel is supported and connected to the short axle through a bearing unit, and a web plate of the resilient wheel is inner-concaved and mounting bases are arranged thereon. The inner-concaved part of the wheel web plate can provide shift space for a driving shaft, thereby avoiding interference; the mounting bases are arranged on the web plate of the resilient wheel, and on each mounting base, the driving shaft is connected with the wheel through two bolts, so that the driving force is transmitted to the wheel through the driving shaft to realize the function of driving the vehicle to run; and the bearing unit with the self-sealing function is adopted, a rear cover is arranged on the resilient wheel and forms maze sealing with a dust ring, and a lamination sealing structure is designed on a bearing cap at the shaft end, thereby preventing dust and sundries from entering the bearing unit.
Description
Technical field
The utility model belongs to 100% low floor city railway vehicle bogie technique field, relates to a kind of motor-car independent wheel bogie axle Biodge device that reduces the vehicle floor height.
Background technology
Trailer in the middle of three modules, 70% low floor vehicle has only adopts independent wheel bogie, reduce height of floor from rail top by the axle Biodge device, but the motor car bogie at two ends still adopts traditional form, and the zone on full car floor about 70% is the low floor district, and all the other are high floor area; In order to make full car floor level all is the low floor district, must take measures to reduce the height of high floor area, therefore, the two ends motor car bogie also must adopt independent wheel to form, and the actuating device of power truck is transferred to lateral wheel from the centre, the axle Biodge device also must carry out the structure change accordingly, to satisfy the needs of transmission of drive force.70% existing low floor independent axle Biodge device, because axle head need be installed foundation brake rigging, integral structure can't be installed axle drive shaft and earth system.
The utility model content
Technical problem to be solved in the utility model is to make the independent axle Biodge device under the condition of finite space, promptly can satisfy the requirement of structural strength, reliability, again can transmission of drive force, can earth protective device be installed at axle head simultaneously.
For solving the problems of the technologies described above, the utility model provides a kind of 100% low floor motor-car independent wheel bogie axle Biodge device, comprise cambered axle, minor axis, it is characterized in that: on the minor axis by bearing unit support and connection elastic wheel, elastic wheel disc indent and be provided with mount pad.
Bearing unit is fixed on the minor axis by bearing gland, is being provided with dust ring on the minor axis between cambered axle and bearing unit, bonnet is installed on the elastic wheel also and between the dust ring forms labyrinth packing, is provided with the lamination seal ring between elastic wheel and the bearing gland.
The female parts of the utility model wheel web can provide the displacement space for axle drive shaft, avoids interfering; The disc of elastic wheel is provided with mount pad, and axle drive shaft links to each other with wheel by two bolts at each mount pad place, and propulsive effort is passed to wheel from axle drive shaft, thereby realizes the function of powered vehicle operation; Employing has the bearing unit (SKF-BT2-2009A) of self-sealing function, bonnet is installed on the elastic wheel also and between the dust ring forms labyrinth packing, and designed the lamination hermetically-sealed construction at the bearing gland place of axle head, prevent that dust, foreign material from entering bearing unit inside.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a block diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model comprises cambered axle 10, minor axis 9, pass through bearing unit 2 support and connection elastic wheels 1 on the minor axis, elastic wheel disc indent and be provided with mount pad 11, bearing unit is fixed on the minor axis by bearing gland 3, between cambered axle and bearing unit, be provided with dust ring 5 on the minor axis, be equipped with on the elastic wheel bonnet 4 and and dust ring 5 between form labyrinth packing, be provided with lamination seal ring 6. between elastic wheel and the bearing gland
During use, after whole axle Biodge device assembles, use bolt that axle drive shaft 7 is connected with elastic wheel 1, be used for transmission of drive force; Earth system 8 can be installed in the end of elastic wheel.
