The invention is aimed at improving the existing technology related to the steering function of hand tractors. The structure is small and compact, and applicable to the development and arrangement in a mini-type gear box of a hand tractor; without changing the structure of an existing technical model, the lock-ring double-acting central driving differential mechanism is used to replace the central driving bull-gear in the existing technology, and combined with a jaw steering gear on a steering shaft of the existing technology to form a new steering gear train, and matched with a differential lock operating device, the differential mechanism is opened or locked under the control of a differential lock clutch operating handle, so that the hand tractor can achieve two steering manners i.e. differential driving steering and jaw clutch steering. During actual operation, suitable operation manner can be chosen according to the environmental contents, and as a result, the working efficiency and operation safety under various environments of the hand tractor can be improved.
Description
Technical field
The present invention relates to the central control mechanism and the Effector of tractor, relate in particular to a kind of central control mechanism and Effector of hand tractor.
Background technique
Hand tractor is a kind of small-sized farming, transportation dual-purpose type farm tractor, and it is simple and compact for structure, and type is small and exquisite flexibly, the operation facility, and use face is very wide.
The turning operation method of prior art hand tractor generally adopts the mode of pinching handle to control the clutch an of left side (right side) jaw clutch on the steering shaft in the gearbox, the form of driving wheel power realizes turning to cut off on one side, the steering mode of this principle is very beneficial for the steering manipulation of tractor in the farming of field, laborsaving and effective, but in the road transport operation, steering operation mode with this principle is just very inconvenient, controls effort and is difficult to and hold.It is to take turns one to drive and another is taken turns and realizes under the principle that is cut off power idle running that tooth embedding clutch turns to, during turning because of being subjected to the influence of internal motivation and external drag, under different road environments, the directivity of its control method and turning has uncertain factor.As, under the promotion of driving wheel, can turn on one side when under normal circumstances operation is turned to free pulley, and in gug is advanced, owing to be subjected to the influence of external force of gravity, idler revolution will be greater than the rotating speed of driving wheel under the effect of external force, then necessary reverse operating when gug is turned, level road or up gradient positive operation, then must reverse operating at gug, this gug contrary operation method has been violated the normal steering reaction thinking of people, in practical operation, very easily make mistakes, exist great potential safety hazard! This is that prior art hand tractor handling maneuver principle is beneficial to the field farming and is unfavorable for transporting and advances that operation can not finely take into account operation under the various ambient Properties and under cover of driving safety hidden danger is obviously not enough.
Summary of the invention
Purpose of the present invention can not finely be taken into account operation under the various ambient Properties at prior art hand tractor steering operation principle and control deficiency on the safety, on the basis that does not change prior art hand tractor basic structure principle, a kind of lock ring type double-acting central authorities' transmission differential mechanism and differential lock operating device are provided, with the central transmission gearwheel on the central transmission differential mechanism replacement of the improved mode usefulness lock ring type double-acting prior art hand tractor steering shaft, cooperate new steering shaft train of composition with the tooth embedding steering gear spare on the prior art steering shaft, cooperation is with differential lock operating device, under the controlling of differential lock Joystick, stir differential lock ring left and right displacement and open or lock differential mechanism, differential mechanism plays differential action during unlatching, each parts of differential mechanism form the effect that an integral body only plays a central transmission gearwheel during locking, thereby realize that free differential steering of hand tractor and tooth embedding clutch turn to the handling maneuver mode of two kinds of different modes, to improve operation adaptability that hand tractor holds and control Security in varying environment.
The object of the present invention is achieved like this: lock ring type double-acting central authorities' transmission differential mechanism and differential lock operating device, comprise lock ring type double-acting central authorities' transmission differential mechanism and the differential lock operating device that is used with it, and it is characterized in that:
