Abstract
The utility model relates to a rear axle driving device of a tractor, which comprises a differential gear, a semiaxis bushing, a semiaxis and a brake drum. An inner supporting tube is fixedly installed in the semiaxis bushing, the semiaxis is inserted into the inner supporting tube, and the brake drum is sheathed on the inner supporting tube through a bearing. A brake drum subpanel is arranged on the outer end of the semiaxis, and the axial outer end of the brake drum is tightly connected with the brake drum subpanel through a screw. The semiaxis only bears torque without wearing with the inner supporting tube, and radial and axial forces caused by the bounce force of a roadway are both act on the inner supporting tube, so the semiaxis is protected. The utility model has the characteristics of long service life, simple structure and good manufacturability.
Description
The utility model belongs to the vehicle transmission gear technical field, specifically relates to a kind of tractor rear axle actuating device.
The power of existing tractor rear axle is passed through the semiaxis that is inserted in the axle tube by differential gear, directly drive brake wheel and order about wheel, during load-carrying, be subjected to the diametral load that the ground-surface bounce causes and the effect of axial force, easy to wear and the fracture of semiaxis, service life is short; The patent No. is 95230651 " a kind of agricultural three travelling wheel car back axles ", is provided with flanged central siphon at the two ends of axle housing, and its semiaxis is located in the central siphon, the axial outer end of brake wheel is provided with flange, though its performance improves to some extent, there is semiaxis drawback easy to wear equally in its complex structure.
The purpose of this utility model provides a kind of semiaxis intensity height, long service life, traffic safety failure-free tractor rear axle actuating device.
For achieving the above object, the utility model comprises axle tube, be inserted into the semiaxis in the axle tube, axle the inner of semiaxis is inserted in the differential gear, the axle outer end is connected with brake wheel, it is characterized in that: also fixedly be fitted with interior support tube in axle tube, semiaxis is inserted in this in support tube, brake wheel by bearing installation on interior support tube, the outer end of semiaxis is provided with a brake wheel subpanel, and the brake wheel axial outer end is fastenedly connected by screw and this brake wheel subpanel.
For easy to assembly, above-mentioned interior support tube outer wall is designed to stepped, simultaneously for turn to flexibly, sliding performance is good, and two groups of bearings are installed between interior support tube and brake wheel, separate with a spacer between two groups of bearings.
After adopting said structure; because of brake wheel rotates around the interior support tube in the axle tube; semiaxis only bears torque; and there are not wearing and tearing between the interior support tube; the diametral load and the axial force that cause from the ground-surface bounce all act on the interior support tube; so semiaxis is protected; long service life; also improve simultaneously load-carrying ability and car load and exercised performance; again because said structure is the brake wheel to prior art; semiaxis and axle tube have been done improvement; and interior support tube can adopt the general-duty solid drawn pipe to process; other parts are existing general part, and are therefore simple in structure, good manufacturability.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Accompanying drawing is an axial cut-away view of the present utility model.
Tractor rear axle actuating device shown in the drawings, comprise the axle tube 2 that is connected on the rear axle stand, employing shrinkage method fixedly is inserted into the interior support tube 3 in the axle tube 2, semiaxis 8 is inserted in this interior support tube 3, leave the gap between interior support tube 3 inwalls and the semiaxis 8, brake wheel 7 is installed on the interior support tube 3 by bearing 5, axle the inner of semiaxis 8 is inserted in the differential gear 1, the axle outer end of semiaxis 8 is provided with a brake wheel subpanel, and brake wheel 7 axial outer end are fastenedly connected by screw 9 and this brake wheel subpanel; Above-mentioned interior support tube 3 outer walls are stepped, brake wheel 7 is installed on the interior support tube 3 by two groups of bearings 5, separate with a spacer 4 between two groups of bearings 5, on the sleeve pipe 3 of the axial outer end of bearing 5, be provided with clamp nut 6, clamp nut 6 outer ends have packing ring, are screwed between packing ring and the clamp nut 6.
