Abstract

The utility model relates to a claw type clutch, belonging to the engaging and disengaging gear of the transmission mechanism of an agricultural machine. The utility model is characterized in that a fixed plate [4] and a clutch shaft [6] are fixedly arranged on the wheel hub of the driving wheel of a small four wheel tractor; the clutch shaft [6] is sequentially sheathed with a spring [8], a clutch circular wheel [9], a cushion ring [10], a clutch claw [11], a clutch claw [12], a cushion ring [10], a clutch gear [13], and a check ring [5]; the utmost outside is fixed on the clutch shaft [6] through a split pin [7]; the clutch claw [11] is connected with an adjusting pull plate [1] through a shaft [2]; the clutch claw [12] is connected with a pull plate [3] through the shaft [2]; the adjusting pull plate [1] and the pull plate [3] are connected through the shaft [2]. The utility model has the advantages of simple structure, light weight, steady separation and convenient operation.

Description

Claw clutch

Technical field

The utility model belongs to farm machinery driving mechanism engaging and disengaging gear, is installed on the tractor with small four wheels rear drive sprocket.

Background technique

At present, be installed in the transmission clutch of the miniature seeding machine on the tractor with small four wheels, generally adopt the wedge shift fork, vertical pulling slides and separates, owing to conducted oneself with dignity and ground top wave impact, makes to separate and loses efficacy, and causes running to be in the state of interlock easily.

Summary of the invention

Technical problem to be solved in the utility model is that existing oblique shift fork structure is changed into the jaw clutch structure, overcomes the sagging and top wave impact influence of deadweight, guarantees to be in the normal separation state all the time.

Technical problem to be solved in the utility model realizes by following scheme:

A kind of claw clutch, form by clutch shaft 6, clutch circle wheel 11, clutch gear 13 etc., it is characterized in that fixed plate 4 and clutch shaft 6 are fixedly mounted on the tractor with small four wheels driving wheel wheel hub, on clutch shaft 6, be set with spring 8, clutch circle wheel 9, packing ring 10, clutch pawl 11, clutch pawl 12, packing ring 10, clutch gear 13, back-up ring 5 successively, outermost is fixed on the clutch shaft 6 with cotter pin 7, clutch pawl 11 usefulness axle 2 is connected with regulates arm-tie 1, clutch pawl 12 usefulness axle 2 is connected with arm-tie 3, regulates between arm-tie 1 and the arm-tie 3 with spools 2 to be connected.

The utility model compared with prior art has following beneficial effect:

1, the ground injustice is jolted when producing impact force, and it is not had influence, the energy held stationary, and separation is firm, does not have the sagging landing phenomenon of deadweight;

2, simple in structure, in light weight, flexible to operation.

Description of drawings

Fig. 1 is the claw clutch structural representation;

Fig. 2 is a clutch pawl Facad structure schematic representation;

Fig. 3 is Fig. 2 clutch pawl A-A cross-sectional view;

Fig. 4 is a clutch circle wheel cross-sectional view;

Fig. 5 is the clutch gear cross-sectional view.

More than among each figure: 1. regulate arm-tie, 2. spool, 3. arm-tie, 4. fixed plate, 5. back-up ring, 6. clutch shaft, 7. cotter pin, 8. spring, 9. clutch circle wheel, 10. packing ring, 11. clutch pawls, 12. clutch pawls, 13. clutch gears.

Embodiment

Further specify below in conjunction with accompanying drawing: clutch shaft 6 and fixed plate 4 are fixedly mounted on the tractor with small four wheels driving wheel wheel hub, on clutch shaft 6, be set with spring 8, clutch circle wheel 9, clutch pawl 11, clutch pawl 12, clutch gear 13, back-up ring 5 successively, clutch is grabbed 11 usefulness axle 2 and is connected with adjusting arm-tie 1, clutch pawl 12 usefulness axle 2 is connected with arm-tie 3, regulates between arm-tie 1 and the arm-tie 3 with spools 2 to be connected.Clutch pawl 11, clutch pawl 12, adjusting arm-tie 1 and arm-tie 3 be parallelogram in one plane, be upwards to lift to regulate arm-tie 1 as shown in Figure 1, parallelogram is near being straight line, and clutch pawl 11 and clutch pawl 13 inclined-plane spacing maximums make clutch circle wheel 9 cut off clutch gear 13.Change to approaching square from straight line to pressing down adjusting arm-tie 1 parallelogram, clutch pawl 11 and clutch pawl 12 inclined-plane spacing minimums make the clutch circle take turns 9 and cut clutch gears 3.That is to say by regulating arm-tie 1 to affect arm-tie 3, clutch pawl 11, clutch pawl 12 to produce four limit parallel motions, clutch pawl inclined-plane associative transformation changes clutch circle wheel 9 and clutch gear 13 axial spacings, under spring 8 effects, and the function of finish branch, closing.

Claims

1, a kind of claw clutch, be by clutch shaft [6], clutch circle wheel [11], clutch gear compositions such as [13], it is characterized in that fixed plate [4] and clutch shaft [6] are fixedly mounted on the tractor with small four wheels driving wheel wheel hub, on clutch shaft [6], be set with spring [8] successively, clutch circle wheel [9], packing ring [10], clutch pawl [11], clutch pawl [12], packing ring [10], clutch gear [13], back-up ring [5], outermost is fixed on the clutch shaft [6] with cotter pin [7], clutch pawl [11] is connected with axle [2] and regulates arm-tie [1], clutch pawl [12] is connected with arm-tie [3] with axle [2], regulates between arm-tie [1] and the arm-tie [3] to be connected with spool [2].
