Embodiment Construction
[0023] Such as Figure 1 to Figure 3 As shown, the two-way reset mechanism with positioning function for locomotive brake controller adopts modular design, and is used for locomotive brake controller to control the braking or release of railway rolling stock. The two-way reset mechanism includes a fixed plate 8, a positioning wheel 9, a reset lever 10, a first elastic mechanism 12,13, a second elastic mechanism 16,17, and a positioning mechanism 15,19,21; wherein,
[0024] The positioning wheel 9 is arranged in the cavity of the fixed plate 8 and has a gap with the inner wall of the fixed plate 8. The side of the positioning wheel 9 is sequentially provided with a first positioning groove 901, a second positioning groove 902, and a third positioning groove 901 from bottom to top. Groove 903, positioning wheel 9 bottoms are provided with reset groove 904; The distance between reset groove 904 and first positioning groove 901 is A, the distance between first positioning groove 9...

The invention discloses a two-way resetting mechanism for a locomotive brake controller and the brake controller. The two-way resetting mechanism comprises a fixing plate, a positioning wheel, a resetting rod, a first elastic mechanism, a second elastic mechanism and a positioning mechanism, wherein the positioning wheel is arranged in a cavity of the fixing plate, a first positioning groove, a second positioning groove and a third positioning groove are sequentially formed in one side of the positioning wheel from bottom to top, and the bottommost end of the positioning wheel is provided witha resetting slot; the top of the resetting rod is provided with a convex portion which can be clamped into the resetting slot, a middle portion is rotatably connected to the fixing plate through a hinge pin; one side of the bottom of the resetting rod is in butt joint with one end of the first elastic mechanism, and the other opposite side is in butt joint with one end of the second elastic mechanism; the other end of the first elastic mechanism and the other end of the second elastic mechanism are both in butt joint with the fixing plate; one end of the positioning mechanism can be clamped in the first positioning groove, the second positioning groove or the third positioning groove, and the other end of the positioning mechanism is in butt joint the fixing plate. The two-way resetting mechanism adopts a modular structure, can achieve two-way resetting, has a positioning function and has high work reliability.
Description
technical field [0001] The invention belongs to the field of locomotive braking systems, in particular to a bidirectional reset mechanism for a locomotive brake controller and a brake controller. Background technique [0002] The resetting mechanisms on the existing locomotive brake controllers are all unidirectional resetting mechanisms, which cannot realize the bidirectional resetting function. [0003] With the development of the locomotive market and technology, there is a requirement that the automatic brake controller and the individual brake controller be set separately. "0" position, "2" position and "1" position, each gear position corresponds to a micro switch to synchronously feed back the change of its mechanical position signal. When the operating handle is manipulated to the "4" or "1" position, when the external force is removed, the operating handle can stop at the "4" or "1" position; the operating handle is manipulated to the "3" or "2" position When the ...
