Description
Technical field
The present invention relates to a kind of tractor load type infinitely variable transmissions.
Background technique
Currently, existing farm tractor is mostly manual shift operation, operating process is complicated, and trouble of shifting gears is laborious, consumption
Oily high, shift process is easy to appear Caton phenomenon, and tire easily skids, and power output is insufficient, and torque is small, and power loss is serious,
Unevenness is engaged between shift process middle gear and gear, abnormal sound is easy to appear and beats tooth phenomenon, gently then influences gear life, it is heavy then straight
Connect damage gear, in addition, middle-size and small-size tractor due to space limitation bar position setting and its it is unreasonable, do not meet man-machine work
Journey, it is very high to the requirement of driver's driving ability, it is unfavorable for operating and using.
Summary of the invention
It is an object of the invention to overcome disadvantages mentioned above, a kind of tractor load type infinitely variable transmission is provided, it is mainly solved
Mechanical, hand-driven gear shift operation of having determined is complicated, and trouble of shifting gears is laborious, and shift process has damage and tractor output power not to gear
Foot, torque is small, and power loses the problems such as serious.The object of the present invention is achieved like this, tractor load type infinitely variable transmission
By: diving board, torque-converters, torque-converters axis, torque-converters partition, gear pump driving wheel, wheel stand, wheel stand bearing, first bearing, from
Clutch cabinet, clutch wheel seat, piston, clutch disc, spring, high speed driving tooth, clutch shaft, second bearing, gearbox every
Plate, distributary base, low speed driving tooth, high speed driven tooth, low speed driven tooth, clutch driving tooth, gear pump spline housing, third axis
It holds, gear pump driven wheel, fourth bearing, sliding sleeve gear, output driven shaft, mud mode gear, 5th bearing, long axis, the 6th
Bearing, driving mode gear, arable land mode gear, gearbox body, 7th bearing, inlet valve, gear pump, goes out output driving shaft
Mouth valve, manipulation valve are constituted.Diving board is mounted on torque-converters, and torque-converters is mounted on wheel stand, wheel stand and clutch cabinet phase
Connection, torque-converters axis is mounted on wheel stand by wheel stand bearing, and is connected with torque-converters, and gear pump driving wheel is mounted on
On torque-converters, it is meshed with gear pump driven wheel, and torque-converters partition, gear pump are housed between torque-converters and gear pump driving wheel
Driven wheel is mounted on gear pump spline housing, and gear pump spline housing is mounted on clutch cabinet by 3rd bearing, inlet valve,
Gear pump, outlet valve are mounted on clutch cabinet, and clutch shaft one end is mounted on clutch cabinet by first bearing, separately
One end is mounted on speed change separator for container by second bearing, and clutch wheel seat is mounted on clutch shaft, piston, spring, clutch
Device piece, high speed driving tooth, low speed driving tooth are installed on clutch shaft respectively, and distributary base is mounted on speed change separator for container, clutch
Driving tooth is mounted on torque-converters axis, and is meshed with clutch wheel seat, and long axis is mounted on output driving shaft, and and torque-converters
Axis is connected, and low speed driven tooth, high speed driven tooth are mounted on output driving shaft, and output driving shaft passes through 6th bearing, the 7th
Bearing is mounted on gearbox body, and driving mode gear, arable land mode gear are mounted on output driving shaft, and output driven shaft is logical
Cross fourth bearing, 5th bearing is mounted on gearbox body, manipulation valve be mounted on gearbox body, sliding sleeve gear, mud mode
Gear is mounted on output driven shaft.The product it using high efficiency, high reliability fluid torque-converter, do not need to change manually
Gear, simple to operate, it is time saving and energy saving to shift gears, and is not in that gear engages abnormal sound and beats to gear without damage in shift process
Tooth extends the service life of gear, solves that traditional tractor output power is insufficient, torque is small, power is lost
Seriously, the low problem of operating efficiency, it was proved that 55 horsepowers of stepless speed changing tractor torques increase compared to same tractor
One times or more big, tractive force is not less than 110 horsepowers of common tractors, because the torque-converters in the tractor infinitely variable transmission can
To play the role of changing torque and horsepower, maximum torque that product utilization torque-converters is not excavated makes up row
The torque of the tractive force and power output walked changes the fuel delivery and gear pump of torque-converters, improves revolving speed, keeps torque-converters defeated
Torque reaches the maximum torque that should reach to supply power output shaft and walking gear axis out, therefore, can reach and exceed
More than half of similar product torque tractive force, stepless speed changing tractor have overload protection function, and when load excessive will not go out
Now flame-out phenomenon, water temperature and high oil temperature will not be generated because of engine overload influences the service life of engine, can be effective
Protection front-rear axle and engine, the service life of tractor can be extended, shift accelerates steady, and speed can be accurate with varying duty
Control can make engine reach best power source point and economic point under any working environment, and the operation time saves oil plant, reduces
The production cost of user improves farming efficiency.
