It is connected to sliding.27 both sides of the power throwout sleeve end face adjacent with rack rails transmission gear 21, axle drive gear 22 it
Between set synchronization clutch.The operating mechanism steering maneuver throwout sleeve 27 is moved axially along main shaft 4, is passed through
Power is transferred to rack rails transmission gear 21 or power is transferred to axle drive gear 22 by synchronization clutch.
With reference to Fig. 2, the operating mechanism is made of driving lever 29, through-rod piston oil cylinder 30, is driven by through-rod piston oil cylinder 30
The front end of driving lever 29 stretch into the circumferential groove of power throwout sleeve 27, power throwout sleeve 27 is driven to make directly along main shaft 4
Line moves back and forth.
With reference to Fig. 2, the synchronization clutch includes rotating speed matching disc 23, circumferential lock pin 24, spring 25, connection
Bar 26 and notch spring ring 28.27 upper edge of power throwout sleeve is provided at circumferentially spaced axially extending bore, pacifies in each axially extending bore
The connecting rod 26 axially across 27 main body of power throwout sleeve is filled, notch spring ring 28 is caught in the circumferential groove of power throwout sleeve 27
Interior, 26 middle part setting annular groove of each connecting rod, under original state, notch spring ring 28 is caught in the annular groove at 26 middle part of connecting rod.Institute
It states 23 upper edge of rotating speed matching disc and is provided at circumferentially spaced axial step hole, connect the 26 both ends axial direction with rotating speed matching disc 23 respectively
Stepped hole is threadedly coupled, the outer end setting spring 25 in axial step hole and the circumferential lock pin 24 by its effect；The rotating speed
End face outside with disk 23 has an annular frustum, on rack rails transmission gear 21, the end face of axle drive gear 22 corresponding thereto then
With the annular cone slot being adapted therewith, rack rails transmission gear 21,22 upper edge of axle drive gear are provided at circumferentially spaced and circumferential direction
24 corresponding locking hole of lock pin.To improve transmission efficiency, adhere to high friction system on the annular frustum, annular cone rooved face
Number coating.
Below by taking rack drives state as an example, illustrate the operating process of switchover apparatus：
Under original state, the piston rod of through-rod piston oil cylinder 30 is located at middle position, synchronous dynamic throwout sleeve in operating mechanism
27 are located at middle position, and notch spring ring 28 is caught in the annular groove at the middle part of notch spring ring 28, left side, right side right-hand rotation speed matching disc 23
To be arranged symmetrically, annular frustum is bored with annular on rack rails transmission gear 21,22 end face of axle drive gear on rotating speed matching disc 23
Slot is separated, and main shaft 4 drives power throwout sleeve 27 to dally.At this point, on rack drives gear 12, axle drives gear 13
Unpowered input.
The oil inlet Q oil inlets of piston oil-cylinder 30, oil inlet P oil extraction, piston rod move to left, and driving lever 29 moves to left therewith, driving lever 29
Power throwout sleeve 27 is driven to move to left.It is caught in due to notch spring ring 28 in the annular groove at 26 middle part of connecting rod, connecting rod 26 is opposite
27 position of power throwout sleeve is fixed, and therefore, switching device integrally moves to left, the annular frustum and tooth of the rotating speed matching disc 23 in left side
The annular cone slot of rail transmission gear 21 starts to engage, and is acted on by frictional force, the speed of rack rails transmission gear 21 starts to improve.
In the case that rack rails transmission gear 21 and 27 rotating speed of power throwout sleeve difference are larger, the circumferential lock on left side rotating speed matching disc 27
Shotpin 24 can not be stretched into the locking hole of 21 annular cone trench bottom of rack rails transmission gear.Later, the rotating speed of rack rails transmission gear 21
It is become closer to the rotating speed of power throwout sleeve 27, it is circumferential after rack rails transmission gear 21 and synchronized power throwout sleeve 27
Lock pin 24 is stretched into the locking hole of rack rails transmission gear 21, and rack rails transmission gear 21 and power throwout sleeve 27 pass through week at this time
It is connected to the axial direction of lock pin 24, mechanically ensure that the rotating speed phase of power throwout sleeve 27 and rack rails transmission gear 21
Together.
The further oil inlets of oil inlet Q of piston oil-cylinder 30, piston rod are further driven to driving lever 29 and move to left, due to power at this time
Throwout sleeve 27 and rack rails transmission gear 21 are synchronized rotation, therefore power throwout sleeve 27 is relative to rack rails transmission gear 21
Stationary state.When driving lever 29 is more than the thrust of power throwout sleeve 27 locking for connecting rod 26 of notch spring ring 28
After power, power throwout sleeve 27 continues to be moved to the left relative to connecting rod 26, and notch spring ring 28 is shunk, notch spring ring 28
It is detached from connecting rod 26, hereafter power throwout sleeve 27 is engaged with the spline sections on rack rails transmission gear 21, at this time rack rails
Transmission gear 21, power throwout sleeve 27, main shaft 4 are whole, and the power for carrying out main shaft 4 is directly inputted to rack rails transmission
Gear 21, rack rails transmission gear 21 are meshed with rack drives gear 12, and rack drives gear 12 and rack rails are meshed and drive row
Garage into.
The wheel track mode of traction of train moves to right process for power throwout sleeve 27, unanimous on the whole with the above process, therefore not
It repeats.
The above is a kind of some principles of rack rails train dynamics switching device of the present invention that explain through diagrams, and is not
By the present invention be confined to shown in and the concrete structure and the scope of application in, it is therefore every it is possible that is be utilized corresponding repaiies
Change and equivalent, belong to the apllied the scope of the claims of the present invention.
