Abstract
The utility model relates to a compact tractor front-drive assembly, which comprises a front bridge shell body and a front transmission shell body which is fixedly connected on the two ends of the front bridge shell body. A front bridge box is arranged in the central position of the front shell body; a front bridge compensation gear is mounted in the front bridge box; a front end cap is fixedly mounted on the front end of the front bridge box corresponding to the front bridge compensation gear; a left hub and a right hub are respectively mounted on the front transmission shell body which is disposed on the two ends of the front bridge shell body; a transverse pull rod is connected between the left hub and the right hub; a steering arm is mounted through a rotating shaft on at least one side of the front bridge shell body; the steering arm comprises a master arm and an idler arm connected into a whole; the idler arm is connected with at least one hub. The steering arm is characterized in that a hydraulic cylinder is mounted between the master arm and the front end cap, one end of the hydraulic cylinder is hinged on the front end cap by a rotating shaft, the other end is hinged on the master arm by a rotating shaft, and the oil inlet and oil outlet of the hydraulic cylinder are connected with an oil pump and a steering mechanism by oil pipes. The compact tractor front-drive assembly connects the front bridge shell body and the front bridge box into a whole, thereby improving the mechanical strength of the front bridge; and adopts hydraulic steering, thereby resulting in more flexible and reliable steering.
Description
Technical field
The utility model relates to a kind of compact trac. before driving assembly.
Background technology
The steering hardware of existing trac. is mechanical steering, and complex structure turns to effort, because the mechanical precision of trac. is lower, mechanical steering gear is through regular meeting's et out of order again.Especially the trac. that in green house of vegetables, uses, the claimed structure compactness, manoeuvrable, common mechanical steering can not meet requirementses, and complicated fluid-link steering can't be installed on the parts of compactness again.In addition, the propons housing of common trac. is two housings that lay respectively at propons case both sides, and bad mechanical strength is damaged easily.
Summary of the invention
The purpose of this utility model provides a kind of fluid-link steering, compact trac. before driving assembly that mechanical strength is high of adopting.
For achieving the above object, the utility model is by the following technical solutions:
A kind of compact trac. before driving assembly described in the utility model comprises the propons housing, be fixedly connected on the preceding transmission housing at propons housing two ends, the midway location of propons housing is the propons case, front axle differential is installed in the propons case, be installed with front end cover with the front end of the corresponding propons case of front axle differential, on the preceding transmission housing at propons housing two ends, be separately installed with a left side, right two wheel hubs, on a left side, be connected with intermediate rod between right two wheel hubs, at least therein by rotating shaft spindle arm is installed on the propons housing of a side, spindle arm comprises master arm and the slave arm that is connected in one, slave arm is connected with one of them wheel hub at least, it is characterized in that: between master arm and the front end cover hydraulic actuating cylinder is installed, one end of hydraulic actuating cylinder is hinged on the front end cover by rotating shaft, the other end is hinged on the master arm by rotating shaft, and the oil inlet of hydraulic actuating cylinder is connected with oil pump and steering hardware by oil pipe with oil outlet.
Above-mentioned propons housing and propons case are connected in one.
The utility model is connected in one propons housing and propons case, has improved the mechanical strength of propons.Simultaneously, adopt fluid-link steering, turn to more flexible, reliable.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of compact trac. before driving assembly described in the utility model comprises propons housing 1, is fixedly connected on the preceding transmission housing 2 at propons housing 1 two ends, the midway location of propons housing 1 is a propons case 11, and propons housing 1 is connected in one with propons case 11.Front axle differential 6 is installed in the propons case 11, be installed with front end cover 12 with the front end of front axle differential 6 corresponding propons casees 11, on the preceding transmission housing 2 at propons housing 1 two ends, be separately installed with left and right two wheel hubs 21, be connected with intermediate rod 4 between left and right two wheel hubs 21, the effect of intermediate rod 4 is that the wheel hub 21 of both sides is realized swing synchronously.By rotating shaft spindle arm 5 is installed on the propons housing 1 of a side therein.Spindle arm 5 comprises master arm 51 and the slave arm 52 that is connected in one, master arm 51 and slave arm 52 all are fixedly connected on steering arm shaft and put, the spindle arm axle sleeve is installed in the spindle arm rotating shaft again, in the spindle arm rotating shaft with bolt be installed in propons housing 1 above, perhaps also can directly on propons housing 1, cover a spindle arm rotating shaft with its one is set.
The oil inlet of hydraulic actuating cylinder 7 is connected with oil pump and steering hardware by oil pipe with oil outlet.The principle of work that relates to hydraulic actuating cylinder partly is existing known technology, and this no longer describes in detail again.
During use, handle the action of the piston rod of liquid dispensing valve modulated pressure cylinder 7 by steering hardware, thereby can drive spindle arm 5 swings, realize the swing of wheel hub 21, reach the purpose that turns to by the action of piston rod.
