Abstract
Seize installation motor spring suspension device, including with the axle end connection ring and elastic element that seize motor side connection ring that rotor output end connect, connect with axle, the peripheral peripheral wall of motor side connection ring and axle end connection ring is arranged at intervals with the boss being interspersed, elastic element is wrapped in the periphery of the boss, and has the wedge block in insertion adjacent lands gap.Motor side connection ring of the present invention is connect with rotor output end is seized, axle end connection ring is connect with axle, motor side connection ring is connected with axle end connection ring by elastic element, boss gap is inserted with wedge shape rubber block, wedge shape rubber block has good torsion pass, flexibility and damping property, displacement capabilities are strong, transfer power on axle by the wedge shape rubber block.Transmission is just transmitted to axle from motor by spring suspension device through the invention, and complicated gear shift is saved in centre, is saved a large amount of structure space and is reduced unsprung mass.
Description
Technical field
The present invention relates to one kind and seizes installation motor spring suspension device, for the driving force of motor to be transferred to axle.
Background technique
Due to the factor of track circuit irregularity, the rail traffic vehicles based on wheel rail system must in actual moving process
A large amount of vibration can be so generated, with the increase of distance travelled, the change of wheel track state, as rail corrugation, wheel lose circle, tyre tread
Removing and scratch etc., vibration can more come also acutely.Rail vehicle suspension parts will be subjected to the test of various random vibrations, elasticity
The operating environment for the vehicle that suspension arrangement design exactly fully considers, in order to reduce the impact and fatigue vibrated to suspension parts
The influence in service life, and be applied in the design of rail vehicle suspension parts structure.
Rail traffic vehicles power truck mainly provides power by motor, realizes wheel rolling movement.State at present
Interior major part traction electric machine is fixed on bogie frame by the frame mode of hanging, and framework and wheel pass through single stage suspension between
Device realizes vibration-damping function, but with the continuous development of bogie technique, directly seizes peace there are also a kind of driving motor at present
On axle, such case, wheel is transmitted on electric machine structure vibration by between, to the structural reliability and usability of motor
Stabilizability is all very big test, therefore spring suspension device design is considered in existing organization plan, it will maximum journey
The suffered vibration and impact of the reduction motor of degree.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the disadvantages mentioned above of the prior art, provide one kind and seize installation electricity
Machine spring suspension device.
In order to solve the above technical problems, provided by the invention seize installation motor spring suspension device, feature exists
In: including being suitble to and seizing motor side connection ring, the suitable axle end connection connecting with axle that rotor output end is connect
The peripheral peripheral wall of ring and annular resilient element, the motor side connection ring and axle end connection ring is arranged at intervals with boss, motor
The boss of the boss and axle end connection ring of holding connection ring is interspersed, and the elastic element is wrapped in the outer of the boss
It encloses, and there is the wedge block in insertion adjacent lands gap.
In order to solve the above technical problems, the present invention also has the feature that
1, the wedge block is bonded with adjacent lands.
2, the outer surface of the boss opens up radial screw hole, and bolt passes through elastic element and fixes elastic element and boss.
3, cushion block is lined between the bolt and elastic element.
4, the motor side connection ring is connect by axial bolts with rotor output end.
5, axle end connection ring and axle are interference fitted.
Motor side connection ring of the present invention is connect with rotor output end is seized, and axle end connection ring is connect with axle, electricity
Generator terminal connection ring is connected with axle end connection ring by elastic element, and boss gap is inserted with wedge shape rubber block, by the wedge shape
Rubber block transfers power on axle.Transmission is just transmitted to axle from motor by spring suspension device through the invention, intermediate
Complicated gear shift is saved, a large amount of structure space is saved and reduces unsprung mass.The wedge-shaped rubber of boss gap insertion
Blob of viscose has good torsion pass, flexibility and damping property, and displacement capabilities are strong.
Detailed description of the invention
The present invention will be further described below with reference to the drawings.
Fig. 1 is that the present invention seizes installation motor spring suspension device structural schematic diagram.
Fig. 2 is that the present invention seizes installation motor spring suspension device scheme of installation.
Specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment seize installation motor spring suspension device, including by axial bolts 2 with
Motor side connection ring 1, the axle end connection ring 9 and ring-type with axle interference fit for seizing the connection of rotor output end 11
The peripheral peripheral wall of elastic element 7, motor side connection ring 1 and axle end connection ring 9 is arranged at intervals with boss 3,4, motor side connection
The boss 3 of ring 1 and the boss 4 of axle end connection ring 9 are interspersed, and elastic element 7 is wrapped in the periphery of boss 3,4, bullet
Property element 7 have insertion adjacent lands gap wedge block 8.The outer surface of boss 3,4 opens up radial screw hole, and bolt 5,6 passes through
Elastic element is fixed by elastic element and boss 3,4, and cushion block is lined between bolt and elastic element.After bolt is tightened, wedge block 8
It is bonded with adjacent lands.Driving force is transmitted by wedge block 8, the suffered vibration and punching of motor can be reduced to the greatest extent
It hits.
In addition to the implementation, the present invention can also have other embodiments.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
