Description
Technical field
The present invention relates to a kind of farm machinery, and in particular to a kind of light track tractor.
Background technology
Existing crawler tractor uses parallel crawler belt layout pattern, its driving wheel, tensioning wheel and thrust wheel arrangement into a line, referred to as parallel crawler belt layout pattern.Due to its driving wheel, tensioning wheel and thrust wheel arrangement into a line, driving wheel radius just determines that the terrain clearance in its axle center is smaller, and live axle center line is overlapped with the end output shaft shaft centre line of transmission case, therefore, this arrangement form just determines that its road clearance is smaller.And machine is in paddy-field-working, the size of its road clearance, directly affect machine by performance, the farmland operation scope that can be applicable is greatly reduced.Meanwhile, transmission system is too near from muddy water in running, adds the abrasion of driving member, reduces the service life of machine.
Conventional tracks tractor steering generally uses manpower and pulls control stick, and cut-out transmission case side driving-chain is reached by machine driving and is realized, is operated, operated laborious, slow in reacting to turning to swing arm by the strength of mechanical zip.
When current crawler tractor is braked, generally use, while pulling back left and right turn control stick, original structure needs both hands to manipulate simultaneously, if synchronous easily cause is misrouted to steering deviation；And brake force is produced by the pulling force of two arms completely, it is relatively elaborate.And during brake operating, take two hands so that other operations can not be carried out simultaneously, reduce production efficiency.
Handling maneuver handle and agricultural machinery and implement the lifting control crank of the agricultural machinery such as existing crawler tractor are provided separately, and respectively take charge of each duty.Machine is generally required while completing steering and agricultural machinery and implement two kinds of Job Operations of lifting, machine hand needs the quick conversion between two control cranks, nervous and busy when farm work runs to the edge of a field；The problems such as Yi Fashengyin operates the agricultural machinery and implement damage caused not in time or farming roughness descent.
Existing self-rescue system is fixed on the capstan winch being connected with driving wheel by steel wire rope, and the other end is set on anchor pole.When driving wheel is rotated, steel wire rope is tightened up in capstan winch rotation winding in left and right, and anchor motionless in soil is inserted by front, machine is pulled along, departs from mire.Because its capstan winch is the outside that is installed at left and right sidesing driving wheel, in order to allow steel wire rope not touch crawler belt, capstan winch must outside cantilevered out 300 ~ 400mm.So very big alternating bending load can be added to two driving wheel semiaxis, half axle fracture is easily caused, the reliability of complete machine is influenceed.The power point two lines that the transmission case of crawler tractor produces engine are transmitted：One is directly delivered to power output shaft through transmission case front portion, to drive agricultural machinery and implement；Another is delivered to driving wheel after transmission case multi-stage speed-reducing, to overcome running resistance and produce tractive force.Therefore, under normal operation, the final gear of transmission case is not subject to all torsion torque of engine generation.And in the case of the machine of falling into, to allow capstan winch to produce enough pulling force, all torsion torque that engine is produced, and amplify step by step through power train, it can all be applied on the final gear of power train, easily cause the catastrophe failure of Gear Root fracture, make machine at a standstill.
