Abstract
A kind of motor suspension mechanism that rolling stock can be changed with lateral stiffness, it is characterised in that：It is connected by sliding bearing between the motor and framework, for realizing when motor stress between framework relative to motor axial free movement, 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, can be considered and axially can be freely moved relative to motor between framework when 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 being adapted to friction speed grade and line condition.
Description
Technical field
The utility model is related to trolley coach bogie motor suspension mechanisms, can be changed more particularly, to a kind of lateral stiffness
Suspension device of motor.
Background technology
The bogie that 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 increased vehicle to the effect of the power destruction 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 to use 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 is motors to be directly connected with framework, and electric machine casing is equipped with mounting base,
Directly it is connected with framework by bolt.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.
Utility model content
The purpose of this utility model, which is to provide one kind, can realize motor suspension stiffness tuning, improve vehicle operation stability
Motor suspension mechanism.
To achieve the above object, the utility model provides a kind of motor suspension machine that rolling stock lateral stiffness is variable
Structure, it is characterised in that：Connected by sliding bearing between the motor and framework, for realizing when motor stress between framework
Relative to motor axial free movement, 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 sliding bearing is mounted on suspension sunpender, and suspension sunpender connects framework.
The suspension sunpender is two, is connected to the upper and lower ends of framework, 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 the mechanism for referring to be adjusted 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 utility model is connected by sliding bearing with framework, when can be considered motor stress with phase between framework
Motor axially can be freely moved.It avoids motor oscillating to couple with framework, greatly reduces motor oscillating to framed intensity
The influence of generation.Compact-sized, easy for installation, rigidity is adjustable.It is larger for the promotion of high-speed cruising bogie stationarity, while can
To adapt to friction speed grade and line condition.
Description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the side view of the utility model.
Specific implementation mode
Referring to Fig.1, Fig. 2, specific embodiment of the present invention include motor 1, sliding bearing 2, spring 3, bolt or insert
Pin 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, for realizing electricity
One spring 3 is respectively set, is used for relative to motor axial free movement, the both sides of sliding bearing 2 between framework 5 when 1 stress of machine
Decay motor oscillation crosswise, and the outside of each spring 3 respectively connects a bolt or bolt 4 respectively, by adjusting bolt or bolt
Length reach the adjustment to 3 initial compression amount of spring, with achieve the purpose that adjust rigidity.
