Abstract
The utility model relates to a driving axle that is used for the land scraper and the special vehicle. The driving axle is provided with an integral-typed axle shell; the left side and the right side of the axle shell are respectively firmly connected with two balancing boxes through a conical bearing; a central main transmission mechanism is installed at the central part of the integral-typed axle shell, and is respectively connected with a driving chain wheel that is arranged at the middle part of the balancing box through two axles, and is connected with a driven chain wheel, a transmission shaft, a bearing shaft and a wheel planetary reduction gear which are arranged in front of and at the back of the balancing box, through four units of transmission chains in a transmission way; a wet-typed arrester is arranged between a rim reduction gear and the balancing box, and is connected with the planetary reduction gear and the transmission shaft in turn through a connection bolt; the brake pressure disc of the wet-typed arrester is matched and lapped with an arrester shell in a closing way into a whole body through an arrester floating oil seal. The structure, positioning and stress of all parts of the driving axle are reasonable, thereby being free from causing the structure loss and failure; the driving axle has strong reliability, convenient maintenance, good radiation property and long service life, and is a good product for updating.
Description
Technical field
The utility model relates to a kind of drive axle structure of vehicle, especially a kind of road grader, engineering special-use vehicle drive axle.
Background technology
At present, the drive axle that uses on road grader and the engineering special-use vehicle because tandem-driving bogie is connected with bolster, left and right sides reducer shell by bearing seat, can make tandem-driving bogie cross the location, and is stressed unreasonable, easily causes left and right sides reducer shell to damage; Bolster not only is subjected to bending moment force but also be subjected to torsional forces, easily causes wheel hub to connect and loses efficacy and the bolster inefficacy; Chain-driving is positioned at final stage, can cause structure huge, and reliability is low, easily loses efficacy; Drg is based on shoe type, jaw type, and braking potential is little, the life-span is low, easy inefficacy.
Summary of the invention
In order to overcome the shortcoming of the drive axle that present road grader and engineering special-use vehicle use, the utility model provides a kind of road grader, special-use vehicle drive axle, the structure at this each position of drive axle, location, stressed rationally, can not cause structural failure and inefficacy; Its good reliability, easy to maintenance, thermal diffusivity good, long service life, is the good product that updates.
The concrete scheme that its technical matters that solves the utility model adopts is: this machine is by central main drive gear, integral housing, semiaxis, tandem-driving bogie, drive sprocket, messenger chain, transmission shaft, bolster, wheel limit planetary reduction gear, tapering bearing, oil-immersed multi-disk brake, assembled by movable sprocket, tapering bearing; It is characterized in that: this drive axle has the integral housing of an one-piece construction, and in the and arranged on left and right sides of axle housing, the tandem-driving bogie by two groups of tapering bearings and both sides is connected and fixed respectively, makes the bending moment force of tandem-driving bogie and torsional forces obtain reasonable balance; Central authorities' main drive gear is installed in the centre of integral housing, it is semiaxis by left and right two takeoff outputs and the drive sprocket connection that is installed in the tandem-driving bogie middle part respectively, and by being connected transmission by movable sprocket, transmission shaft, bolster and wheel planetary reduction gear before and after four groups of messenger chains orders and the tandem-driving bogie; Oil-immersed multi-disk brake is installed between wheel reduction gear and the tandem-driving bogie, and it is connected with planetary reduction gear and transmission shaft by the tie bolt order, and the braking platen of oil-immersed multi-disk brake cooperates closed assembly to be integral by the drg float grease seal with the arrester shell osed top.
Its beneficial effect is: each position structure of this drive axle, location, stressed reasonable, can not cause structural failure and inefficacy; Its good reliability, easy to maintenance, thermal diffusivity good, long service life, is the good product that updates.
