Abstract
A kind of variable motor suspension mechanism of rolling stock lateral stiffness, it is characterised in that：It is connected between the motor and framework by sliding bearing, compared with motor axial free movement between framework when being used to implement motor stress, the sliding bearing both ends installation has elastic component, for the motor oscillation crosswise that decays, stiffness tuning mechanism is installed between the elastic element and framework, for adjusting elastic element initial compression amount, so as to adjust the rigidity of motor suspension mechanism.The suspension mechanism is that motor is connected by sliding bearing with framework, axially can free movement compared with motor between framework when can be considered motor stress.It avoids motor oscillating to couple with framework, greatly reduces the influence that motor oscillating generates framed intensity.Compact-sized, easy for installation, rigidity is adjustable.It is larger for the promotion of high-speed cruising bogie stationarity, while it is adapted to friction speed grade and line condition.
Description
Technical field
The present invention relates to trolley coach bogie motor suspension mechanism, more particularly, to a kind of variable motor of lateral stiffness
Suspension arrangement.
Background technology
The bogie of frame suspension type is used for motor suspension mode, since most of quality of traction electric machine is matter under spring
Amount, this had not only added vehicle to the power destruction effect of track but also the impact generated wheel track and vibration is directly passed to traction
Motor increases the mechanical load of motor.More fearful, this interaction force increases rapidly with the raising of speed
Greatly, so the structure is generally used on low speed power bogie.
Current most common motor suspension mode is using a kind of motor hanger, and traction electric machine is mounted on motor hanger
On, then motor hanger is connected to by flat spring on bogie frame, motor hanger therein uses welding structure, produces work
Skill is complicated, and overall structure weight is larger.Also one kind is that motor is directly connected with framework, and electric machine casing is equipped with mounting base,
Directly it is connected by bolt with framework.Without buffer element, motor oscillating and framework coupling influence kinetics between motor and framework
Can, while the vibration generated generates large effect to framed intensity.
The content of the invention
The object of the present invention is to provide one kind can realize motor suspension stiffness tuning, improve the electricity of vehicle operation stability
Machine suspension mechanism.
To achieve the above object, the present invention provides a kind of rolling stock lateral stiffness variable motor suspension mechanism,
It is characterized in that：It is connected between the motor and framework by sliding bearing, it is opposite between framework when being used to implement motor stress
In motor axial free movement, sliding bearing both ends installation has elastic component, described for the motor oscillation crosswise that decays
Elastic element and framework between stiffness tuning mechanism is installed, for adjusting elastic element initial compression amount, so as to adjust motor
The rigidity of suspension mechanism.
The sliding bearing is mounted on suspension sunpender, suspension sunpender connection framework.
The suspension sunpender is two, is connected to the upper and lower ends of framework, and motor is hung by upper and lower two suspensions
Sliding bearing on bar is connected with framework.
The elastic element is steel spring, rubber spring, air spring, hydraulic buffer.
The stiffness tuning mechanism is to refer to the mechanism being adjusted to elastic original paper initial compression amount, including but not
Be limited to adjust automatically, manually adjust, hydraulic control, electronically controlled mechanism.
The motor of the present invention is connected by sliding bearing with framework, when can be considered motor stress between framework compared with
Motor axially can free movement.It avoids motor oscillating to couple with framework, greatly reduces motor oscillating and framed intensity is generated
Influence.Compact-sized, easy for installation, rigidity is adjustable.It is larger for the promotion of high-speed cruising bogie stationarity, while can fit
Answer friction speed grade and line condition.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the side view of the present invention.
Specific embodiment
With reference to Fig. 1, Fig. 2, the specific embodiment of the invention include motor 1, sliding bearing 2, spring 3, bolt or bolt 4,
Framework 5, it is upper and lower two suspension sunpender 6, it is upper and lower two suspension sunpender 6 on be respectively set with a sliding bearing 2, be used to implement motor 1
Compared with motor axial free movement between framework 5 during stress, the both sides of sliding bearing 2 respectively set a spring 3, for decaying
Motor oscillation crosswise, the outside of each spring 3 each connects a bolt or bolt 4 respectively, by adjusting the length of bolt or bolt
Degree reaches the adjustment to 3 initial compression amount of spring, to achieve the purpose that adjust rigidity.
