Operating principle of the present utility model is：
During multiplexing energy car job run, train control system controls magnetic valve to the air feed of clutch cylinder 10, cylinder 10
Motion drives piston rod 12, shift fork 13, sliding axle 16 to axially move to the left, and sliding axle 16 promotes back-moving spring 18 to do synchronous shifting
Dynamic, gear shifting force is stored in back-moving spring 18, meanwhile, shift fork 13 stirs gearshift tooth set 7 and does synchronizing moving to the left, when gearshift tooth set
7 reach setting stroke with the second spline housing 6 by lead-in chamfered 7a with the drive range for being moved to setting, i.e. cylinder 10 is merged
When, steel ball 23 is moved in left locating slot 19 under the holding of retaining spring 24 from the right locating slot 20 on sliding axle 16, installation
The sending signal of proximity switch 11 on cylinder 10, low speed axle gear box can be passed to by ensuring that the power of motor 1,
And the drive range of clutch is secured by steel ball 23, it is not moved, realize the job run of multiplexing energy car.
During multiplexing energy car running under power, power inputs high-speed carriage-axle gearbox by hydraulic transmission gear box, and a power part passes through
Axletree passes to wheel pair, and another part passes to low speed axle gear box by universal drive shaft, and the power of low speed axle gear box leads to
Cross axletree and pass to wheel pair, in order to prevent low speed axle gear box is counter from dragging motor 1 to cause its damage, now need Train Control system
System control magnetic valve drives piston rod 12, shift fork 13, sliding axle 16 to do to the right the air feed of clutch cylinder 10, the motion of cylinder 10
Axial movement, the gear shifting force that is stored in back-moving spring 18 also promotes shift fork 13 and stirs gearshift tooth and cover 7 simultaneously does to the right synchronization
Mobile, when gearshift tooth set 7 departs from the second spline housing 6 with the drive range for being moved to setting is merged, i.e. the stroke of cylinder 10 is answered
During position, left locating slot 19 is moved in right locating slot 20 steel ball 23 from sliding axle 16 under the holding of retaining spring 24, installation
The sending signal of proximity switch 11 on cylinder 10, when ensuring that vehicle running under power, motor 1 can depart from low speed axletree
Gear-box, and the drive range of clutch is secured by steel ball 23, realize the switching of locomotive traction operating mode and working condition.
When vehicle breaks down, train control system is unable to automatic control clutch cylinder 10 when being shifted gears, and can pass through
Opponent moves gear shaft 25 and is operated manually, and making shift fork 13, moving gear shaft 25 does axial reciprocating movement conveniently, is stirred by shift fork 13
Tooth set 7 of shifting gears moves, the combination or disengaging of gearshift tooth set 7 and the second spline housing 6, again by changing for the fixed clutch of steel ball 23
Gear is put, it is achieved thereby that manual shift process.
, it is necessary to explanation, term "left", "right", " level ", " interior ", " outer " etc. in description of the present utility model
The orientation or position relationship of instruction are to be based on orientation shown in the drawings or position relationship, are for only for ease of description the utility model
Described with simplifying, rather than the device or element of instruction or hint meaning there must be specific orientation, with specific orientation structure
Make and operate, therefore it is not intended that to limitation of the present utility model.
