Description
Technical field
The utility model belongs to grassland fire fighting truck field, more particularly to a kind of double disengaging type drivers of grassland fire fighting truck
Structure.
Background technology
In the fire fighting truck of grassland clutch main function be separation and closed engine and driving wheel power transmission, for
The grassland fire fighting truck that the design of clutch is current mainly has the solution using two kinds.One kind is to use flywheel structure, flywheel
The characteristics of structure is more at present to be applied in bicycle, it is maximum is the continuity and ease for operation of power transmission, is not required to
Other mechanisms are wanted to realize separation and the closure of power.Another kind is to use jaw clutch structure, jaw clutch
Bearing capacity is stronger, but the moment of its separation and closure can produce larger impact.
Utility model content
In order to solve efficiency, load and the operational issue of grassland fire fighting truck clutch designs at the same time, the utility model provides
A kind of double disengaging type transmission mechanisms.The so-called double clutches of the mechanism are to be surmounted by a helical spline jaw clutch with one
Formula clutch is formed.The mechanism can make clutch reduce impact when combining, and energy consumption be reduced, so that grassland fire fighting truck more supernumerary segment
Can environmental protection.
The technical solution of the utility model is to improve a kind of double clutch transmission mechanism of grassland fire fighting truck, including bullet
Spring, jaw clutch power ratchet, flower-drum end ratchet, flower-drum, main shaft, directional overrunning clutch, sprocket wheel, flower-drum left end bearing,
Flower-drum right end bearing, it is characterised in that：
Spring is used to abut jaw clutch power ratchet, the outer ring of left flower-drum bearing and the left bearing mating surface of flower-drum
Close-fitting, inner ring and the main shaft slide fit of left flower-drum bearing；
The outer ring of right flower-drum bearing and the right bearing mating surface close-fitting of flower-drum, inner ring and the main shaft slide fit of right flower-drum bearing；
Flower-drum end ratchet is connected by bolt and flower-drum；
Axle sleeve is connected by spline with main shaft, and is fixedly connected with by screw and freewheel clutch shell；Sprocket wheel and override type
Clutch outer member is fixedly connected with by rivet；
Power ratchet is coordinated by helical spline and main shaft, and ratchet baffle ring is connected with main shaft by circlip groove.
The beneficial effects of the utility model are:
1. transmitting moment of torsion by jaw clutch, larger moment of torsion can be transmitted, ratchet tooth intensity is higher to bear
Certain impact, it is reliable and stable.
2. clutch separation process is rapid, it is kept completely separate after separation, additional clutch drag will not be produced.
3rd, helical spline can be automatically locked after clutch combination, avoid the possibility departed from when traveling.
4th, after adding directional overrunning clutch, clutch impacts reduction in cohesive process, can effectively reduce energy consumption.
Brief description of the drawings
Fig. 1 is the structural front view of the utility model.
Wherein：1st, spring, 2, jaw clutch power ratchet, 3 flower-drum end ratchets, 4, flower-drum, 5, axle sleeve, 6, main shaft,
7th, directional overrunning clutch, 8, sprocket wheel, 9, flower-drum left end bearing, 10 flower-drum right end bearings.
Embodiment
The utility model is further described in conjunction with attached drawing 1:
As shown in Figure 1, a kind of double clutch transmission mechanism of grassland fire fighting truck is present embodiments provided, including spring 1, tooth
Embedded-type clutch power ratchet 2, flower-drum end ratchet 3, flower-drum 4, axle sleeve 5, main shaft 6, directional overrunning clutch 7, sprocket wheel 8, flower-drum are left
End bearing 9, flower-drum right end bearing 10.
The outer ring of left flower-drum bearing 9 and the left bearing mating surface close-fitting of flower-drum 4, inner ring and the main shaft 6 of left flower-drum bearing 9 are slided
Match somebody with somebody；
The outer ring of right flower-drum bearing 10 and the right bearing mating surface close-fitting of flower-drum 4, inner ring and the main shaft 6 of right flower-drum bearing 10
Slide fit；
Flower-drum end ratchet 3 is connected by bolt and flower-drum 4；
Axle sleeve 5 is connected by spline with main shaft 6, and is fixedly connected with by screw and 7 shell of freewheel clutch；Sprocket wheel 8 is with surpassing
More 7 shell of formula clutch is fixedly connected with by rivet；
Power ratchet 2 is coordinated by helical spline and main shaft 6, and ratchet baffle ring is connected with main shaft by circlip groove；Left axle end
The outer ring of bearing and left axle end bearing block close-fitting, its inner ring and main shaft slide fit, and fastened by left axle end nut and main shaft；Right axle
The outer ring of end bearing and right axle end bearing block close-fitting, its inner ring and main shaft slide fit, and fastened by right axle end axle sleeve 5 and main shaft；
Left axle end bearing block is fixed with right axle end bearing block and grassland fire-fighting vehicle carriage.
Double clutch transmission processes：After grassland fire fighting truck accelerates, after manually drag-line pulls, helical spline dental inlay
Formula clutch separation, power ratchet 2 is along helical spline away from flower-drum end ratchet 3.Wheel realizes idle running.When grassland fire fighting truck is slided
Row arrives certain speed, and loosen the clutch drag-line, and jaw clutch power ratchet 2 is under the action of the spring to flower-drum end ratchet 3
End movement, is combined and the auto lock under the action of helical spline with flower-drum end ratchet 3.At this time, engine is not actuated, and wheel turns
Speed is higher than chain wheel speed, and due to the presence of freewheel clutch 7, wheel is rotated further, and kinetic energy loss is little；Then engine opens
Dynamic, power reaches directional overrunning clutch 7 by sprocket wheel 8, when 8 speed of sprocket wheel is more than directional overrunning clutch 7, directional overrunning clutch
7 is locked, and power reaches directional overrunning clutch 7 along sprocket wheel 8, then reaches main shaft 6, power ratchet 2, flower-drum end ratchet 3 and finally pass
To wheel.Grassland fire fighting truck is driven to advance.
Although the principle of the utility model is described in detail above in conjunction with the preferred embodiment of the utility model,
It should be appreciated by those skilled in the art that above-described embodiment is only the explanation to the exemplary implementation of the utility model, and
