Background technology
In prior art, the propons of four-wheel driven loader also has many open, is disclosed among the JP7081442 as application publication number: be provided with planetary gear speed reducing mechanism on the back axle and be provided with the walking driving device of rim brake wheel type loader on the differentiator output shaft.Employing is inserted hydraulic pressure wet multi-plate drg in the outer end of the horizontal case portion of differentiator case, the external differentiator that is engaged in is exported on the gear part of axle head, in connect the planetary wheel that is engaged on the Ring gear, support free to rotate is installed on the load-carrying frame on the back axle and constitutes planetary gear speed reducing mechanism, and by axle box and horizontal case portion Ring gear being clipped in the middle fuses.In the differentiator case drg is housed, and is connected with axle box, thereby the inner space can effectively be utilized, and can improve the degree of freedom and the durability of planetary gear speed reducing mechanism by Ring gear.
Then, in above-mentioned disclosed patent, its drg is contained on the axletree and is arranged in the differentiator casing, though utilize differentiator box house branch space, the complexity of parts manufacturing increases, and its manufacturing cost eighteenth of the twenty is expensive; Because drg is arranged on the axletree in case damage bad maintenance, need pull down HM Hydraulic Motor, pull down transmission shaft, pull down the HM Hydraulic Motor retarder, the differentiator that need take Transmission Bridge at last apart just can keep in repair, general drg maintains also is inconvenient to carry out, maintenance cost Gao Mao also needs the maintainer of specialty just can carry out.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of propons of loader is provided, and front axle differential and rear-axle differential are rotated synchronously; Can when driving of the wheel type loader of four wheel drive or Parking, provide propulsive effort or braking force to actuating device by the back axle circular cone driving gear shaft; Good seal performance, the reliability height, low cost of manufacture, easy to maintenance.
Main solution of the present utility model is achieved in that
The utility model mainly adopts at main speed reduction box body front end bearing connection and cover cap is installed, and cover cap, bearing connection are fastened on the main speed reduction box body, and the propons circular cone driving gear shaft is installed therein; The propons circular cone driving gear shaft is connected transmitting power by transmission shaft propons attaching parts with transmission shaft, the other end is installed propons circular cone driving gear and the engagement of propons circular cone ring gear, feature is the nest that described bearing connection is provided with protrusion, and is provided with two centre concentric shafts bearings spaced apart from each other at described nest center.
Two the concentric shafts bearings in described nest center also can link to each other.
Described nest is provided with seal groove.
Described nest cooperates with the main speed reduction box body, makes installation propons circular cone driving gear shaft wherein vertical mutually with the diff output shaft.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to adopt the utility model structure, make that the main parts size of propons and back axle is general, reduce the complexity of parts to greatest extent and save manufacturing cost, front axle differential and rear-axle differential rotate synchronously simultaneously; Can when driving of the wheel type loader of four wheel drive or Parking, provide synchronous propulsive effort or braking force to actuating device by forward and backward bridge circular cone driving gear shaft; Good seal performance, reliability height, low cost of manufacture, easy to maintenance.
