The specific embodiment

This E P brake controller as shown in the figure, it is a kind of brake controller that is combined and linked by circuit control and gas circuit control.It comprises steering unit, transmission device, circuit control device and directly leaks informaton four parts of device.

Wherein, described steering unit comprises detachable plug-type control handle 2, upper left cover 1 and right upper cover 3, drum assembly 5; Be located at can the peg graft drum assembly 5 of control handle 2 of top is being set in the cover body that upper left cover and right upper cover form, offer groove 33 on the drum 4 in this assembly, in groove, be provided with once the fixing cushion block 26 of socket head cap screw 27 and elastic cylindrical pin 28; Be provided with simultaneously one and cooperate fixing 24 firmly with drum 4 in the centre hole of drum 4, be milled with a platform on its axis body, respectively placing a spring 23 on the flat surface on drum 4 both sides, a locking lever 22 of being with bifurcated minor axis 35 is being supported in the upper end of this two spring 23; If the headtree of locking lever 22 passes the centre hole on the cushion block 26, the structure that formation can link to each other with the plug-in type control handle.

Described transmission device comprises half gear 7, miniature gears 8 and the bar 19 etc. that leaks informaton, and half gear 7 is by screw 29, and pin 30 is fixed on the drum 4, and miniature gears 8 then is installed on spindle assemblies 14 axle heads, and is engagement with half gear 7; In addition, the described bar 19 that leaks informaton, its middle part body of rod is by pin 18 and cross bar 17 bolts, and the collision block 25 on this leak informaton bar 19 upper ends and drum assembly touches, and its lower end then is connected with the bar 20 that leaks informaton of discharge valve cage 21, forms a lever transmission main part.

The circuit control of E P brake controller realizes that by cam 16 and auxiliary contact box 15 cam 16 adopts aluminum alloy materials, and auxiliary contact box 15 adopts Sha Ertebao box of import, and rated voltage is direct current 110V, and rated current is 5A.Consider that auxiliary contact box quantity is more, for reducing volume, the auxiliary contact box adopts the symmetrical close arrangement of intersection, auxiliary contact box 15 is intersected be located on two mounting columns 13 symmetrical the branch.Why adopt this aligning method, be because this E P brake controller transmitting ratio is big, main shaft institute rotational angle is greater than 180 °, according to former method of designing, can only contact box of a cam-controlled, can make that like this controller volume is excessive, the design makes controller smaller and more exquisite in order to dwindle overall volume, and contact box adopts the symmetrical close arrangement of intersection.

The described device that leaks informaton comprises the valve rod 20 that leaks informaton, discharge valve cage 21, and described discharge valve cage 21 is anchored between right side board 6 and the latus inframedium 11 by socket head cap screw 10, and links to each other with the lever 19 that leaks informaton in the transmission device by the overhanging valve rod 20 that leaks informaton.

The braking principle of above-mentioned controller is as follows:

In the technical solution of the utility model, be located at the detachable control handle in the groove between the right cover body of left cover body, have 13 control positions when pulling before and after in groove, promptly " overcharge ", " running ", " system 1 ", " system 2 ", " system 3 ", " system 4 ", " system 5 ", " system 6 ", " system 7 ", " system 8 ", " system 9 ", " heavily joining " and " promptly "; Only when " heavily connection " position, after control handle just can be inserted into interlock system in the drum assembly 5, and avoid upper left cover, 31 pairs of drum assemblies of the limiting stopper on the right upper cover are operated.

When manipulation control handle 2 rotated drum assembly, half gear 7 drove miniature gears 8 interlocks that are engaged with; Because a side is provided with a spring leaf 32 below drum assembly 4, the screens wheel by this reed front end just can cooperate the ratchet 34 in the drum assembly, makes drum 4 in the location positioning that control handle 2 needs, and finishes corresponding brake operating control.And in case in case of emergency, when needing drum assembly 4 to turn to " promptly " braking position, be located at collision block 25 extruding the leaking informaton lever 19 on the drum assembly 5, make and leak informaton lever around pin 18 rotations, and by removing to promote to leak informaton valve rod 20 in this lever lower end of leaking informaton; Because this horizontal motion that leaks informaton valve rod 20 makes the high pressure gas that can control and impel train braking in the train discharge from the air outlet of discharge valve cage 21, realizes the compressed air brake under the emergency state; Meanwhile, when this position, cam on the spindle assemblies 14 16 is realized closings of circuit with corresponding auxiliary contact box 15, indirect operation the switching of locomotive electropneumatic valve, realize leaking informaton braking.Thereby two kinds of functions of leaking informaton are realized by a controller, reach original intention of the present utility model.
