Description
Technical field
The present invention relates to a kind of express locomotive suspension device of motor.
Background technology
The effect of locomotive engine suspension arrangement is suspension traction electric machine on bogie, and prevents it from falling on track.
Friction speed, the locomotive of heavy-duty class have different requirements to hang.The hang of motor is broadly divided into axle suspension formula (again
It is referred to as rolling and seizes semimounted) and frame suspension type (being also called integral) 2 kinds.Typical axle overhung construction is: traction electric machine is pacified
Being contained on bogie frame, motor shaft is parallel with axletree.Motor one end is by being arranged on the pair of bearings in motor suspension system
Supporting, axletree is around bearing rotary.The other end is fixed on the support of truck transom by motor suspension rod.Typical structure such as Fig. 1 institute
Show.
In the design of locomotive, between the spring of bogie, quality and rotary inertia have significant impact to the stability of locomotive,
And prior art mainly has the disadvantage that:
1, unsprung mass is big.The quality of the nearly half of motor weight motor by taking turns undertaking, higher unsprung mass, cause wheel
Rail active force is big, and in particular with the raising of the speed of service, wheel-rail dynamic interaction significantly increases.
2, the working condition of the critical piece such as traction electric machine, bearing and traction gear is severe.
3, the elasticity of torsion that stiff shaft overhung construction drives is poor, tends to cause the overload of DC traction motor even to damage
Bad.The structure of elastic shaft suspension type is the most relative complex, and the buffering played is the most very limited.
4, the structures shape of axle suspension formula is only suitable for below 120km/h speed class locomotive, it is impossible to meet express locomotive
Requirement.
Summary of the invention
Solved by the invention technical problem is that overcomes the deficiencies in the prior art, it is provided that between a kind of spring, quality is little, and elasticity is even
Connect, there is the express locomotive suspension device of motor of function that is spacing and that decouple simultaneously.
The technical solution used in the present invention is that express locomotive suspension device of motor, motor and gear-box are rigidly connected, motor
Being connected by bolt sleeve and hexagon socket head cap screw with front support seat, motor is connected by check bolt with rear branching holder, motor
Being hung on framework front beam by front support seat, motor connects motor suspension rod by rear branching holder and hangs on truck transom,
Gear-box is hung on truck transom by gear-box suspension rod, the horizontal stop that the baffle plate on rear branching holder is on truck transom
In the middle of seat, and keep certain gap.The special baffle arrangement of rear branching holder, can realize jointly with the horizontal stop seat of framework
Keep gap, cross spacing function, limit excessive lateral displacement.
Front support seat is connected with gear-box by bearing.The arcuate structure of front support seat and hollow axle concentric fits, and with
Gap is there is between hollow axle.Front support seat is connected on truck transom by rubber arthrosis.Front support seat passes through bolt sleeve
It is connected with motor.Motor suspension rod and gear-box suspension rod are connected on framework front beam by rubber arthrosis.Bolt sleeve ensure that
The flexibility connected, alleviates shock and vibration.Rubber arthrosis can absorb vertical, longitudinally, laterally vibrational energy, effectively reduces and turns to
Frame vibrates, and is more beneficial for being adjusted to rigidity each, absorbs different frequency of vibration.It is provided with anti-between motor and truck side sill
Coupling vibration damper, is prevented effectively from the resonance of motor and framework, makes the lateral inertia of motor and gear-box and inertia major part of shaking the head
Decouple with whole framework.
Cross spacing stop is bolt-connected on horizontal stop seat.Set between cross spacing stop and laterally stop seat
There is adjustment inserted sheet, during the car that falls, adjust gap according to practical situation, to meet requirement, it is achieved required dynamic performance.
Laterally the envisaged underneath of stop seat has pin-and-hole, and after semi-finished round pin penetrates pin-and-hole, split pin penetrates in semi-finished round pin afterbody through hole.When
When suspension device of motor occurs unexpected coming off, whole device falls on semi-finished round pin, without dropping on track, causes derailing
Or even the major accident such as casualties.
The invention has the beneficial effects as follows that motor suspension uses elastic suspension mode, it is ensured that locomotive has good kinetics
Performance, relatively low wheel-rail dynamic interaction, and combine the function of horizontal stop, it is ensured that less oscillation crosswise and excellent horizontal stroke
To dynamic performance.Use this structure, it is achieved that motor and the elastic suspension structure of framework, framework is horizontal in bogie runs
To vibration or during yawing, motor and driving means can be relative to framework generation transverse movements so that it is lateral inertia and shaking
Head inertia is most of to be decoupled with whole framework, thus reduces the lateral inertia of quality and inertia of shaking the head between the spring of bogie, has
It is beneficial to improve the transversal dynamic performance of bogie, it is to avoid bogie generation Cross deformation phenomenon.Express locomotive motor of the present invention
Suspension arrangement, simple in construction, reasonable in design, there is higher bearing capacity and safety coefficient.
