Abstract
The utility model relates to a jaw clutch mechanism. The clutch can be separated and combined, and the movable jaw clutch body can be automatically positioned at the separation and combination positions. The concrete structure is that a shifting fork (1) with a U-shaped groove at one end is arranged on a frame O1Point hinge joint, a shifting fork head (6) on the shifting fork (1) and an annular groove of the movable clutch body (3) form clearance fit, and a movable frame (4) is arranged at O2The point is hinged with the frame, a pin shaft (7) at the B end of the point is in clearance fit with a U-shaped groove on the shifting fork, and two ends of the spiral spring (5) are respectively hinged with a shaft (12) on the shifting fork (1) and a shaft (13) on the movable frame (4). Adopt the aboveThe structure does not need a positioning mechanism, reduces the axial size of the clutch, and has convenient operation and low manufacturing cost.
Description
The present invention relates to a kind of jaw clutch clutch mechanism.
The clutch mechanism of existing jaw clutch is by the spring of axial installation, and shift fork and locking device thereof constitute.Spring increases axial dimension, and operated clutch makes it combination, separates, and needs the shift fork locking, and operation is inconvenient.
The purpose of this invention is to provide a kind of axial dimension little, simple in structure, cheap, can handle jaw clutch from, close, and make its dynamic interlocking teeth clutch body locate reliable clutch mechanism.
The present invention is by shift fork [1], frame [3] moves about, spring [5] constitutes, clutch from, close and dynamic interlocking teeth clutch body self-locating function is finished by following mode: decide jaw clutch body [2] connect firmly at driven axle [9] go up, dynamic interlocking teeth clutch body [3] forms movingly with driving shaft [10] spline or feather key, dynamic interlocking teeth clutch body [3] can endwisely slip on driving shaft, connect firmly the fork slot F that is positioned on the dynamic interlocking teeth clutch body [3] at the shift fork head [6] on the shift fork [1] and form Spielpassung, shift fork [1] and frame [8] are at O
1Point articulated, connect firmly the U-groove bevel formation Spielpassung that is positioned at shift fork [1] at the bearing pin [7] of frame [4] one ends that move about, frame that moves about [4] and frame [8] are at O
2Point hinge connection, be in all the time extended state helical spring [5] two ends respectively with shift fork [1] on axle [12] and axle [13] hinge on the frame that moves about [4] join.When the need clutch, operation shift fork [1] makes it around O
1The point counterclockwise dotted line position from Fig. 1 turns to solid line position.When rotating, shift fork [1] makes dynamic clutch body [3] and the teeth engagement of deciding on the clutch body [2] by the shift fork head [6] on it, and stir the frame that moves about [4] by the U-groove bevel on it and turn to solid line position by the dotted line position of figure in [1], when shift fork [1] and the frame that moves about [4] by Fig. 1 in dotted line position when turning to solid line position, drive helical spring [5] and move to solid line position by dotted line position among Fig. 1, at the clutch state, shift fork [1] is subjected to the pulling force of helical spring [5], by its upper shift fork head [6], dynamic clutch body [3] is applied left active force vertically, stop dynamic clutch body [3] moving to the right, thereby realize engagement location automatically.When the need clutch separation, operation shift fork [1] makes its clockwise direction turn to dotted line position among Fig. 1, realize to separate, location automatically, and self-align principle is identical during with joint.
Advantage of the present invention is an axial dimension simple in structure, that locate reliably, reduced clutch, and easy to operate, low cost of manufacture.
The concrete structure of invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a plan view of the present invention.
Fig. 2 is a side view of the present invention.
Embodiment: decide jaw clutch body [2] and connect firmly on driven axle [9] with known mode, with driving shaft [10] upper spline formation dynamic interlocking teeth clutch body [3] movingly, can on driving shaft, endwisely slip, self-align shifting fork mechanism is made up of shift fork [1], the frame that moves about [4] and helical spring [5], and shift fork [1] and frame [8] are at O
1Locate hinged, angle β between shift fork [1] and the frame that moves about [4] is 81 °, shift fork [1] is gone up and is fixedly connected with shift fork head [6] with known mode, the fork slot F that shift fork head [6] is positioned on the dynamic interlocking teeth clutch body [3] forms Spielpassung with it, when shift fork head [6] is in combination or disengaging configuration at clutch, be positioned on the horizontal symmetry-line [14] of dynamic interlocking teeth clutch [3] cross section, the U-groove bevel [11] of shift fork [1] one end, form Spielpassung with the bearing pin [7] that is fixed on frame [4] one ends that move about, frame that moves about [4] and frame [8] are at O
2Place's hinge connection, have the above pretightening force of 50N helical spring [5] two ends respectively with shift fork [1] on axle [12] and the frame that moves about [4] on axle [13] hinge join, outer rim to the distance between dynamic interlocking teeth clutch [3] axis that is fixed on the axle [12] on the shift fork [1] should be greater than dynamic interlocking teeth clutch [3] flange radius 5mm, the hinge point O of shift fork [1]
1Length O to its U-groove bevel end C
1C is than two hinge point O
1, O
2Between the distance be 4.5mm.
