Background technique
Differential mechanism is the important component of vehicle, its Main Function be while turning for balancing vehicle inside and outside the speed discrepancy of wheel, vehicle can be turned smoothly, but for the vehicle travelling under the comparatively complicated rugged environment of being everlasting as bow-type tractor, differential mechanism has but played reaction, because bow-type tractor is through the die Dorfstrasse of being everlasting, dry river cheuch, the areas such as hilly and mountainous land are used, the road surface situation in this type of area is comparatively complicated, wheel is absorbed in mud, the situation of sandy soil or wheel hanging happens occasionally, in this type of situation, the differential principle of differential mechanism rapidly rotates a wheel of vehicle, and another wheel almost stops, the power that vehicle is not advanced, cause moving ahead, present vehicle is equipped with differential lock for addressing this problem for this reason, differential lock is exactly the wheel jack shaft locking the wheel jack shaft of that wheel stopping and rapidly rotation, it is connected as a single entity, make the vehicle wheel rotation stopping, thereby dynamicly realize moving ahead of vehicle, but current existing differential lockwork is comparatively complicated, handle comparatively loaded down with trivial details, inapplicable as the vehicle of the types such as bow-type tractor.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of structure comparatively simple, operation is differential lock comparatively easily.
The technological scheme that the utility model adopts is: a kind of differential lock is provided, comprise control operating rod, shift fork rocking arm, Returnning spring, shift fork, differential lock slider and differential lock fixed block, described control operating rod is fixedly connected with one end of shift fork rocking arm, the other end of shift fork rocking arm rotates on body by declutch shift shaft, one end of described Returnning spring is connected with shift fork rocking arm middle part, the other end of Returnning spring is connected with body, described differential lock slider slides and is located on wheel jack shaft, differential lock fixed block is fixed on another corresponding wheel jack shaft, on the described differential lock slider end face relative with differential lock fixed block, be equipped with the concaveconvex structure cooperatively interacting, one end of described shift fork is fixed on declutch shift shaft, the other end of described shift fork is connected with differential lock slider.
Described differential lock slider is all connected with wheel jack shaft by spline with differential lock fixed block.
Described differential lock slider and differential lock fixed block are jaw clutch.
The other end of described shift fork is connected with differential lock slider and refers to that differential lock slider is provided with chute, and the other end of described shift fork is entrenched in chute.
Adopt after above structure, compared to the prior art the utility model differential lock has following advantage: when one side of vehicle, wheel is absorbed in mud, during road surface that sandy soil or unsettled and another side wheel have been positioned at, apply External Force Acting on control operating rod, shift fork rocking arm is rotated around its fixed end, fork rocking arm drives Returnning spring to extend energy storage, fork rotates together simultaneously, fork is stirred differential lock slider and is moved along wheel jack shaft axis, thereby and differential lock fixed block produces relative displacement, both are cooperatively interacted by concavo-convex mechanism, now, two wheel jack shafts combine by differential lock slider and differential lock fixed block, form an integral body, enter differential lock lock state, dynamic torque is all delivered to both sides wheel simultaneously, driving vehicle advances, after vehicle derailing predicament, remove external force, the elastic force of stocking of Returnning spring pulls fork rocking arm to rotate backward, fork is stirred differential lock slider and is moved back to multiple reset condition along jack shaft axis, realize two jack shafts separated, automatically terminate differential locking state, do not having under External Force Acting, effect due to Returnning spring, differential lock is all the time in released state, the utility model structure is comparatively simple, operation more for convenience.
Accompanying drawing explanation
Fig. 1 is that the utility model differential lock is at the schematic diagram of lock state.
Fig. 2 is that the utility model differential lock is at the schematic diagram of unlocking condition.
In figure, 1, control operating rod, 2, Returnning spring, 3, shift fork rocking arm, 4, shift fork, 5, jack shaft, 6, differential lock fixed block, 7, differential lock slider.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As Fig. 1, shown in Fig. 2, the utility model differential lock, act on vehicle two wheel jack shafts 5, comprise control operating rod 1, shift fork rocking arm 3, Returnning spring 2, shift fork 4, differential lock slider 7 and differential lock fixed block 6, control operating rod 1 is fixedly connected with one end of shift fork rocking arm 3, the other end of shift fork rocking arm 3 rotates on body by declutch shift shaft, one end of Returnning spring 2 is connected with shift fork rocking arm 3 middle parts, the other end of Returnning spring 2 is connected with body, differential lock slider 7 slides and is located on wheel jack shaft 5, differential lock fixed block 6 is fixed on another corresponding wheel jack shaft 5, on differential lock slider 7 end face relative with differential lock fixed block 6, be equipped with the concaveconvex structure cooperatively interacting, one end of shift fork 4 is fixed on declutch shift shaft, the other end of shift fork 4 is connected with differential lock slider 7.
The utility model in the specific implementation, differential lock slider 7 is all connected with wheel jack shaft 5 by spline with differential lock fixed block 6, namely two wheel jack shafts 5 arrange spline in the one end away from wheel, the endoporus of differential lock slider 7 and differential lock fixed block 6 is also provided with the spline matching with wheel jack shaft 5, differential lock slider 7 can endwisely slip on wheel jack shaft 5, differential lock fixed block 6 is enclosed within on wheel jack shaft 5, and the disk by axle head is fixed on wheel jack shaft 5.
