Abstract
The invention discloses a high difference device of tractor driving wheel, comprising left and right rockers as final transmission box and left and right sleeves mated on outer peripheral faces of left and right power output semi-shafts. Said left and right rockers have first ends installed on left and right driving wheels and second ends fixed on said left and right sleeves respectively. Said left and right sleeves are connected with gearbox body respectively in running. An oil cylinder is hinged between left or right rocker and tractor frame. Power transmission device, which can make left and right sleeves swing in phase and in reverse direction, is set in said gearbox body. Compared with known technology, it is provided with simple structure and low producing cost. The invention makes walking tractor is suitable for mountains or hill regions with larger gradient.
Description
Technical field
The present invention relates to the trac. technical field, relate in particular to a kind of device of two drive wheel relative heights of scalable trac..
Background technology
The left and right sidesing driving wheel of most of known trac. is fixed on the same axis, can not adjust the relative height of its left and right sidesing driving wheel along with the slope change of walking region, turn on one's side easily when laterally walking along the hillside fields, only suit on the level land or hillside fields operation that the gradient is less, and can not be applied to bigger mountain region of the gradient or intersected country.Chinese patent CN1579121A discloses a kind of hillside tractor, it is arranged at the height difference apparatus of change speed gear box by a cover, drive is rotated simultaneously in opposite directions around the left and right sides connection pipe of left and right moving power output shaft outer peripheral face, the rotation of left and right sides connection pipe makes the rotational of the rocking arm of captive joint with it around the takeoff output semiaxis, make the left and right sidesing driving wheel that is fixed in the rocking arm other end do upper and lower motion, thereby the diff-H of having realized two drive wheels is regulated.Though this height difference apparatus compact conformation of this patent disclosure, use also more convenient,, this height difference apparatus structure is too complicated, manufacturing cost is higher.
Summary of the invention
Technical matters to be solved by this invention is: a kind of height difference apparatus that is used for tractor driving wheel is provided, and this control apparatus is simple in structure, low cost of manufacture.
For solving the problems of the technologies described above, technical scheme of the present invention is: the height difference apparatus that is used for tractor driving wheel, but the left and right rocking arm that comprises the final transmission case body of double as, be provided with the final driving device in a left side between left side takeoff output semiaxis and the left driving wheel, the final driving device in a left side is arranged in the left rocking arm, be provided with right final driving device between right takeoff output semiaxis and the right drive wheel, right final driving device is arranged in the right rocking arm; Be sheathed on the left sleeve pipe of the outer peripheral face of described left takeoff output semiaxis, be sheathed on the right sleeve pipe of the outer peripheral face of described right takeoff output semiaxis, described left rocking arm has first end that is installed on left driving wheel and second end that is fixed in described left sleeve pipe, described right rocking arm has first end that is installed on right drive wheel and second end that is fixed in described right sleeve pipe, a described left side, right sleeve pipe is rotatably connected with gear box respectively, between a described left side or right rocking arm and tractor frame, be hinged with oil cylinder, be equipped with in described gear box inside and can make a described left side, the torque transfer of right sleeve pipe synchronous backward swing, described torque transfer comprises first conical gear that is fixed in described left sleeve pipe, be fixed in second conical gear of described right sleeve pipe, described first conical gear and the second conical gear number of teeth equate, with be fixed in a rotating shaft and respectively with first, the second conical gear ingear the 3rd conical gear, described rotating shaft is rotatably installed on described gear box.
After having adopted technique scheme, the invention has the beneficial effects as follows: owing between a described left side or right rocking arm and tractor frame, be hinged with oil cylinder, the torque transfer that can make described left and right sleeve pipe synchronous backward swing is installed in described gear box inside, when oil cylinder is flexible, by a swing drive left side or the rotation of right sleeve pipe of a left side or right rocking arm; By torque transfer transmission of power is arrived another driven rocking arm again, like this, left and right sidesing driving wheel will move by synchronous backward, realizes the adjusting of diff-H.Compare with known technology, simple in structure, manufacturing and maintenance cost are lower.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the structure diagram of transmission principle embodiment illustrated in fig. 1.
The specific embodiment
The height difference apparatus that is used for tractor driving wheel, shown in Fig. 1 and Fig. 2 were common, change speed gear box 1 was fixed in tractor frame 2.Left and right rocking arm 3,3 ' has first end of the left and right driving of being installed on wheel 4,4 ' respectively and is individually fixed in left and right sleeve pipe 12,12 ' second end, but the final transmission case body of its double as, left and right final driving device 6,6 ' be arranged at left and right takeoff output semiaxis 11,11 ' and left and right driving wheel 4,4 ' between, they can be chain gearing, also can be belt driver or gear system etc.Left and right sleeve pipe 12,12 ' is sheathed on the left and right takeoff output semiaxis 11 of change speed gear box 1,11 ' outer peripheral face respectively, and is rotatably connected with gear box respectively.A described left side or right rocking arm 3 or 3 ' and tractor frame 2 between be hinged with oil cylinder 5, be used to control the swing of a rocking arm.The torque transfer that can make described left and right sleeve pipe 12, the swing of 12 ' synchronous backward is installed in described gear box inside.
Described torque transfer comprises and is individually fixed in described left and right sleeve pipe 12,12 ' and first, second conical gear 13,13 ' of equating of the number of teeth, with be fixed in a rotating shaft 16 and respectively with first, second conical gear 13,13 ' ingear the 3rd conical gear 14, described rotating shaft 16 is rotatably installed on described gear box.Be individually fixed in left and right takeoff output semiaxis 11,11 ' left and right input gear 15,15 ' be arranged at change speed gear box 1 in the speed-changing mechanism (not shown) is connected, be used to accept power, drive left and right takeoff output semiaxis 11,11 ' rotation.
Essence of the present invention is, hinged oil cylinder between tractor frame and rocking arm when oil cylinder stretches, by a torque transfer that is arranged in the gear box, drive the synchronous rocker backswing of opposite side, thereby the diff-H of realizing drive wheel is regulated.Simple with the known technology structure compared, low cost of manufacture uses walker tractor of the present invention to be adapted at the bigger mountain region of the gradient or intersected country uses.
