Abstract
The invention discloses a special high-speed ratio drive axle for special equipment. The special high-speed ratio drive axle for the special equipment comprises a spherical speed reducer shell, a main speed reducer is arranged in the speed reducer shell, a left half axle is arranged at one end of the main speed reducer while a right half axle is arranged at the other end, a hub brake disc assembly is arranged at the outer end of each of the left half axle and right half axle, and a brake caliper is arranged in each hub brake disc assembly. The maximum traction of the drive axle can arrive at 30 tons, the speed reduction ratio of the whole axle is 8.17, the maximum outer diameter of the main speed reducer is smaller than or equal to 370, and accordingly the special high-speed ratio drive axle is capable of guaranteeing the minimum ground clearance when being mounted on a small vehicle, and the trafficability characteristic of the vehicle is improved.
Description
Technical field
The present invention pursues in the industrial vehicle of large traction and machinery for being applied to, and the one belonged in the special dimensions such as demand weight traction such as airport, harbour, large ship is exclusively used in special equipment large speed ratio drive axle.
Background technology
Conventional drive axle is as the end of the power drive system of vehicle, machinery, its basic function is: 1. the motor torque transmitted by universal drive shaft is transferred to driving wheel by main reduction gear, diff, semiaxis etc., realize reduction of speed and increase torque 2, realize break-in by drive axle upper reducer conical gear, differential is turned; 3. realize carrying and intermal force by Drive axle housing body and wheel.Therefore, for lifting means tractive force must promote the decelerating power of drive axle, the torque that driving engine is spread out of is increased by reduction of speed, elevating gear tractive property.
But the transmitting ratio of the main retarder drive of single-stage is generally at 3.5-6.7, transmitting ratio will make the oversize of driven wheel of differential too greatly, affects the ground ground Clearance of driving axle housing.Ground Clearance is less, and automobile pass ability is poorer.Due to the restriction by main reduction gear volume, the tractor truck of current domestic application in more than 20 generally all adopts the drive axle of large volume, therefore the corresponding increase of tractor truck volume is caused, thus cannot narrow space be applied to, the special dimension of site contour complexity, constrains resource optimization and the progress in this field.
Summary of the invention
The object of this invention is to provide one and be exclusively used in special equipment large speed ratio drive axle, this drive axle tractive force limit can reach 30 tons, whole bridge reduction ratio is 8.17, and this bridge main reduction gear maximum outside diameter is not more than Φ 370, thus also can ensure road clearance when being loaded on compact car, improve the crossing ability of car load.
Technical scheme of the present invention is as follows;
One is exclusively used in special equipment large speed ratio drive axle, include spherical moderator device shell, in speed reducer housing, main reduction gear is installed, main reduction gear two ends are separately installed with left half axle, right axle shaft, left half axle, right axle shaft outer end are provided with wheel hub brake disk assembly, are provided with brake clamp in wheel hub brake disk assembly.
Described left half axle, right axle shaft are rotatablely equipped with in left axle sleeve, right axle sleeve respectively.
This drive axle of the present invention is a primary speed-down type drive axle, and whole bridge realizes slowing down by the retarder of a stand-alone development.For increasing drive axle installation, drive axle braking model is: caliper disc is braked, both sides respectively adopt upper and lower two big pump diameter single pump systems to move drive axle that pincers make it employing drum brake mechanism more of the same type has the less installation volume of better braking effect thus is more suitable on the tractor truck of most of compact conformation.Tractor engine Driving Torque proceeds to semiaxis by transmission shaft input reducer input end and through retarder thus drives drive wheel to realize car load and drives and traction.
This drive axle structure is compact, and tractive force limit can reach 30 tons, and whole bridge reduction ratio is 8.17 can be loaded on general small size tractor truck, safety, reliable.This product is by test at present, obtains the accreditation of client and has filled up a domestic blank in this field.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
See accompanying drawing, one is exclusively used in special equipment large speed ratio drive axle, include spherical moderator device shell 1, main reduction gear 2 is installed in speed reducer housing 1, main reduction gear 2 two ends are separately installed with left half axle 3, right axle shaft 4, left half axle 3, right axle shaft 4 outer end are provided with wheel hub brake disk assembly 5, are provided with brake clamp 6 in wheel hub brake disk assembly 5, and left half axle 3, right axle shaft 4 are rotatablely equipped with in left axle sleeve 7, right axle sleeve 8 respectively.
