Abstract
The driving device of walking machine and steering unit belong to walking machine driving system medium power output unit and control mechanism thereof.This mechanism increases in the trac. variable ratio drive system and has reequiped some transmissions and control parts, and has designed the interlock steering unit.The run-in synchronism between power take-off shaft and the drive wheel can be realized, and independent operation, easy operation can be distinguished.Rear power output shaft has the operating speed shelves number identical with drive wheel.This mechanism can be used in trac. and other walking machines or other machinery, to enlarge this mechanical versatility.
Description
This mechanism belongs to the power take-off implement and the control mechanism thereof of driving system in the walking machine (as automobile, trac. etc.).
The power take-off implement of walking machine is that engine power is passed to extraneous facility in rotary manner, is the important device that enlarges the walking machine field of application, and technical overview is at present:
According to the position branch on the walking machine of power take-off shaft place, have preposition, put side and postposition.Side-mounted is that certain horizontal shaft extension with change speed gear box goes out outside the housing, and preposition and postposition is to be exported by the change speed gear box tween drive shaft.
Characteristics according to power output shaft speed are divided into: standard revolving speed formula and synchronous mode.The power take-off shaft of standard revolving speed formula has only a design speed.As being defined as 540 ± 10 rev/mins in the agricultural traction engine power take-off shaft standard (NJ76-66), (new suggested is 1000 rev/mins), the commentaries on classics of this output shaft with do not change by the independent manipulation mechanism controls, with the commentaries on classics of drive wheel with do not change irrelevant.
The rear power output shaft of the trac. that has has two rotating speeds, and the shift control mechanism of independent manipulation is arranged in its power output drive system, realizing the high low speed and the stall of output shaft, with the commentaries on classics of drive wheel with do not change irrelevant.
The synchronous mode power take-off shaft be by output shaft of gear-box or with this have drive connection another the axle on draw power, be synchronously or throw off by independent manipulation mechanism controls takeoff output and drive wheel, power take-off shaft has the speed threshold number identical with drive wheel, but when realizing the power take-off shaft different rotating speeds, drive wheel is followed rotation together, can not independently throw off.
Above overview is seen Cheng Yuesun chief editor " trac. design " Chinese agriculture machinery press 1981,9.
Increasing the possible operation type of walking machine, enlarge the range of use of walking machine, is the main prerequisite that solves working in dispersion work mechanization.These are many at operation type, and the operation total amount is little, and the rural area and the backcountry of adynamia or inconvenience are particularly important.Simultaneously, also be the remodeling creation dynamic condition of walking machine.Increase the rotating speed series of power take-off shaft, realize that the interlock of power take-off shaft is very necessary, and require its manipulation easy as far as possible.
Purpose of the present invention is exactly in order to solve transmission device and the existing problem of steering unit that above dynamical axis goes out, and a kind of power take-off shaft that makes of design-calculated has the speed threshold number identical with drive wheel, to satisfy the requirement of different work to speed.And can realize the interlock of power take-off shaft and drive wheel, that is: power take-off shaft rotates, and drive wheel does not change, or opposite; Power take-off shaft and drive wheel rotate simultaneously, or opposite, and adopt a joystick to realize the transmission steering unit of these four kinds of operating modes.
The driving device of walking machine of the present invention and steering unit, it is that rear power output shaft is located at after the diff, its transmission be by the gear [3] on last root axle of change speed gear box drive by bearing [12] supporting be installed in cylinder circular cone dual gear [4] on the differential gear box [7], Bevel Gear Drive [11], to rear power output shaft [10], it is characterized in that between diff and final gear [3], between conical gear [11] and the rear power output shaft [10] power-transfer clutch is housed respectively and controls the steering unit of these two power-transfer clutchs.Power-transfer clutch between said diff and the final gear [3] can be made up of the female splines on the dual gear [4] and clutch cover [5], feather key [6], differential gear box [7] with male splines, the power-transfer clutch between said conical gear [11] and the rear power output shaft [10] can by have outward, the clutch cover [8] of female splines, [9] form.The steering unit of said control clutch is by a joystick [23] and be used for stirring the pole assembly [17] that two two bars that have mutually perpendicular shift fork [18], [19] respectively and be nested together of clutch cover [5], [8] can move at directions X and can form around the push rod assembly [20] that X-axis is rotated.
Below with reference to accompanying drawing invention is further elaborated:
Fig. 1-transmission principle figure
Fig. 2-steering unit diagrammatic sectional view
The A of Fig. 3-Fig. 2 is to view
[1] is gear box casing among Fig. 1; [2] be last root axle of change speed gear box; [3] be constant-mesh cylindrical wheel last in the change speed gear box; [4] be cylinder circular cone dual gear, it is contained on the diff shell [7] by bearing [12], can dally, and promptly rotate and [7] are motionless [4].[6] be the feather key that is contained on the differential gear box [7]; When tooth embedding formula clutch cover [5] meshes with [4], [4], [5], [7] three rotations simultaneously that promptly unify.Rotate drive wheel [15] by diff [13] this moment on the one hand, and the aspect Bevel Gear Drive is paid [11] rotation in addition, if tooth embedding formula clutch cover [8] and [9] are thrown off, though the Bevel Gear Drive rotation, power take-off shaft [10] is motionless.When the tooth embedding formula clutch cover [5] on the differential gear box is thrown off with dual gear [4], [4] go up idle running in [7], differential gear box does not change, drive wheel does not change, but Bevel Gear Drive is still rotated, handle tooth embedding formula clutch cover [8] and [9] engagement or disengagement again, can make rear power output shaft [10] is rotation or slack.
[4], [5], [6], [7] parts are formed the link gear between dual gear and the diff among Fig. 1.[14] are terminal transmission among Fig. 1, and [16] are brake equipment.
Fig. 2 and Fig. 3 are simple two views of the steering unit of this link gear, and part [17] is the pole assembly; " [18] be that power take-off shaft sprinkles the fork assembly; [19] be the diff disengaging yoke; [20] be push rod assembly; [21] be spring; [22] be spacing steel ball; [23] be joystick.
When joystick [23] is swung in the Y direction, can make tooth embedding clutches engaged or disengagement on the power take-off shaft, when joystick [23] when directions X is swung, can make engagement of tooth embedding formula clutch cover or disengagement between dual gear and diff, with joystick not only at directions X but also in the swing of Y direction, to realize the interlock requirement of four kinds of operating modes between power take-off shaft and drive wheel.
This mechanism on can be used on trac., in all requirements the vertical direction takeoff output is arranged, and the power take-off implement of wishing two directions has in walking machine that random interlock requires or other machinery and all can adopt.
This mechanism is compared with the prior art:
(1) this mechanism has more takeoff output speed threshold number than standard revolving speed formula power take-off implement.
(2) with existing synchronous mode power take-off implement relatively, this mechanism can realize the takeoff output of multiple rotating speed under the motionless condition of drive wheel.
(3) this mechanism also can design in rotating speed series and realize standard revolving speed.
(4) this mechanism has only joystick to realize the interlock requirement, though structurally slightly complexity a bit, control comfort.
This mechanism can realize on trac., changes part-structure and also can realize on automobile.
