Description
Technical field
The utility model is mainly concerned with agricultural Transport Machinery apparatus field, refers in particular to the frame-steered tractor that drives before and after a kind of the realization.
Background technology
In the prior art, as important agricultural Transport Machinery equipment, frame-steered tractor is subjected to customer's favor with advantages such as it are simple in structure, with low cost, applicability is strong, is widely used in numerous agricultural transport fields.But, trac. goes up a slope and skids, can not swash and can not run in muddy hollow road, after the trailer load-carrying, front-wheel weightlessness, problems such as conveying efficiency is low have but caused people's attention, so there is the practitioner to propose the scheme of trac. rear drive, generally be that head section to frame-steered tractor improves in these schemes, drive before and after realizing by head gearbox combination one auxiliary gearbox.This structure has the following disadvantages: 1, because the design space of head is limited, therefore the improvement that the head section of frame-steered tractor is carried out, to cause the space of head section narrow and small unavoidably, the layout that is unfavorable for other vitals: 2, because auxiliary gearbox will be realized the transmitting ratio that mates, have to take little modulus, the negative addendum modification design of gears, and each bolster diameter all reduces thereupon, and the high pulling torque transmission of trac. and complicated road conditions need high-intensity driving parts, this shows existing combination odd-side structure too " tender and lovely ", the working environment of incompatibility trac.; 3, very easily damage, repair rate is up to about 50%, and its major failure is: odd-side gear tooth breakage, bolster flexural deformation; 4, inconvenient maintenance.Must earlier head, trailer be separated during maintenance, repair odd-side then.Because of the deceleration and stopping performance of frame-steered tractor, hydraulic lifting performance in head and trailer combination after debugging detects finishes, that is to say that the modular repair of odd-side has caused the debugging testing of complete machine performance, therefore strengthened maintenance load; 5, accessory difficulty, the repair cost height.Because of odd-side design-calculated particularity, make that accessory is difficult to buy in market, incur loss through delay maintenance time, customer complaint is big; 6, compound transmission is only supplied with a rear-guard speed, and must be under the situation of 4 * 4 front and back driving, can not independently use rear-guard to solve the climbing problem, and this structure increases the wearing and tearing of energy consumption and parts.7, increased the Turning radius of trac..
The utility model content
The technical problems to be solved in the utility model just is: at the technical matters of prior art existence, it is a kind of simple in structure, rationally distributed, with low cost that the utility model provides, can improve the overall quality level of trac., reduce the frame-steered tractor that use cost and realized front and back easy to maintenance drive.
For solving the problems of the technologies described above, the solution that the utility model proposes is: the frame-steered tractor that drives before and after a kind of the realization, it comprises head, be mounted on trailer and preceding wheel assembly and rear wheel assembly on the head, preceding wheel assembly is installed on the head, rear wheel assembly is installed on the trailer, it is characterized in that: the diesel engine of described head links to each other with the head change speed gear box, first output shaft in this head change speed gear box links to each other with preceding wheel assembly by semiaxis and conduit, second output shaft in this head change speed gear box links to each other with trailer gearbox on being arranged at trailer by flexible transmission shaft, and the output shaft of trailer gearbox links to each other with rear wheel assembly with back axle by transmission shaft.
Described trailer gearbox further links to each other with a gear type pump by the hydraulic pressure output shaft.
Described trailer gearbox comprises casing and is installed in the interior output shaft of casing, input shaft, trailer gearbox transmission shaft, pass a bridge axle, reverse gear shaft and hydraulic pressure output shaft that output shaft directly upwards is installed with gear Z

The two ends of described flexible transmission shaft link to each other with the output shaft of second universal-joint with head change speed gear box and trailer gearbox by first universal-joint respectively.
Compared with prior art, the utility model advantage just is:
1, the frame-steered tractor that drives before and after of the present utility model the realization can provide 1,2,3,4 grade of rear-guard speed of advance and the 1 grade of rear-guard speed that falls back, and wherein trailer gearbox is advanced 1 grade and can be realized trac. four-wheel driven in synchronism with main-gear box 3 low gears that advance;
2, move behind the frame-steered tractor hydraulic pressure output unit that drives before and after of the present utility model the realization, trailer hydraulic lifting overall performance improves;
3, the frame-steered tractor design that drives before and after of the present utility model the realization can be satisfied this type transmitting large torque needs, and standard is used trac., and guarantee does not have the three guarantees fault in year substantially;
4, to get the parts commonality big for the frame-steered tractor designing institute that drives before and after of the present utility model the realization, and parts are easily purchased.Simultaneously, maximum characteristics are that trailer gearbox does not directly link to each other with head, and maintenance is only carried out at the part.More than two maintenance cost is reduced significantly;
5, because transfer torque is big, the range of use of trac. is constantly enlarged.Thereby further near the requirement of tractor drivers to the trac. cost performance;
6, the frame-steered tractor price that drives before and after of the present utility model the realization is low, compares cost-cutting with former technology and reduces by 1/3;
7, the of the present utility model realization can also be realized 4 * 2 rear drives under the prerequisite that 4 * 4 front and back drive.
