Description
Technical field
The utility model relates to the machine-walking transmission system, and especially a kind of agricultural or building engineering is with the double steering shaft gearbox of walking machine.
Background technology
Existing agricultural or building engineering is with the structure of the matching used change speed gear box of walking machine, comprise casing, and be arranged on power input shaft in the casing, the gear axle, reverse gear shaft and steering shaft, also have live axle or drive deboost axle, the cooresponding supporting meshed transmission gear of each green phase, wherein the output gear at two ends and live axle or the driven wheel that drives two ends on the deboost axle are meshed on the steering shaft, two on the steering shaft turn to the fork controls end to be respectively equipped with the control pinch roller, two control pinch rollers are separately positioned on the upper end of two control levers on the casing, the lower ends of two control levers connect by extension spring, two control pinch rollers respectively with a left side, right two steering operation bars are abutted against.
The equipped agricultural or building engineering walking machine device that adopts the said structure change speed gear box, when a side is turned, operation steering operation bar, make the shift fork that turns to of homonymy stir an end output gear on the steering shaft, it is broken away from and its ingear central driver gear, live axle is run out of steam, the wheel of homonymy stops operating, and the rotation that moves on of the wheel of opposite side, thereby reach the purpose of turning to a side.
The walking machine device of the change speed gear box of equipped this structure, turn radius is bigger, the distance of advancing is bigger, as is used on the reaper, if particularly be used on the walking machine of caterpillar type tavelling wheel, because of the seedlings of cereal crops in the rice field intensive, for fear of damaging paddy by pressure, the distance that reaper advances when turning and the radius of turning can not be excessive, and the device of will operating machine usually retreats twice or thrice just can finish turning, expend a large amount of time, efficient is lower; In addition, retreating during turning is very easy to be absorbed in the mud ground, and understeer is lived, and brings very big trouble to work.Building engineering also can suffer from similar trouble with walking machine device for example grab excavator, bulldozer etc. in the constructing operation process.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, can make agricultural or building engineering is less with walking machine device turn radius, turn fast, efficient is higher, be not easy to be absorbed in mud ground, handle the double steering shaft gearbox of easy and convenient agricultural or building engineering with walking machine and provide a kind of.
The purpose of this utility model is to realize by following technical scheme:
A kind of agricultural or building engineering is with the double steering shaft gearbox of walking machine, comprise casing and be arranged on the interior steering shaft of casing, and live axle or driving deboost axle, the driven wheel that turns to output gear and live axle or drive two ends on the deboost axle at two ends is meshed on the steering shaft, two on the steering shaft turn to the fork controls end to be respectively equipped with the control pinch roller, two control pinch rollers are separately positioned on the upper end of two control levers on the casing, the lower end of two control levers connects by extension spring, two control pinch rollers respectively with a left side, the right steering control lever is abutted against, unlike the prior art be: the secondary steering shaft of setting up an arrangement in parallel in a side of steering shaft, secondary central driver gear on the secondary steering shaft is meshed with the central driver gear on the steering shaft, and the pair at two ends turns to output gear to be meshed with the driven wheel at two ends on live axle or the driving deboost axle respectively on the secondary steering shaft.
Two pairs on the described secondary steering shaft turn to the fork controls end to be respectively equipped with the subcontrol pinch roller.
Described subcontrol pinch roller is separately positioned on the upper end of two subcontrol levers on the casing, and the lower end of two subcontrol levers connects by extension spring.
Described subcontrol pinch roller is abutted against with left and right steering operation bar respectively.
Be respectively equipped with the stroke boss on the described left and right steering operation bar.
Described stroke boss alternately is abutted against with described subcontrol pinch roller of homonymy and control pinch roller in steering operation bar moving process.
The equipped agricultural or building engineering walking machine device that adopts the said structure double steering shaft gearbox, when straight line moving, the pair at two ends turns to output gear to break away from and the secondary central driver gear of its ingear on the secondary steering shaft of setting up, do not participate in the transmission of power, by former steering shaft transferring power, and when a side is turned, operation steering operation bar, make the steering operation bar stir the control pinch roller of homonymy, make and turn to shift fork to stir to turn to output gear, it is broken away from and its ingear central driver gear, the wheel of homonymy is run out of steam stop operating, simultaneously, because the moving of steering operation bar, the stroke boss that is provided with on it alternately is abutted against with subcontrol pinch roller and control pinch roller, therefore, make turn to output gear break away from its ingear central driver gear in, the pair of control homonymy turns to shift fork, make pair turn to output gear and the engagement of secondary central driver gear, outputting power is to the driven wheel of live axle or driving deboost axle.
Because steering shaft and secondary steering shaft are by its central driver gear engaged transmission, therefore pair turns to output gear and turns to the output gear rotation direction opposite, after pair turns to output gear and the engagement of secondary central driver gear, the wheel of homonymy is promptly changed into by the original rotation direction of advancing and retreats rotation direction, the rotation and the wheel of opposite side moves on.One side wheel stops operating during so just by original turning, and the opposite side wheel rotation direction of advancing is changed into side wheel and retreated rotation direction, the opposite side wheel rotation direction of advancing, thereby make turn radius distance less, that need advance shorter, make turning quicker, efficient is higher; Do not need to retreat several times and could turn, thereby in mud ground, be not easy to be absorbed in, handle easy and convenient in same place.
That the utility model is applicable to is agricultural, constructional engineering machinery is with common wheeled or crawler-mounted walking machine device is equipped uses.
