The differential lock has simple structure, simple assembly and operation and effective avoidance of malfunction incidence rate.
Description
Technical field
The utility model relates to a kind of automobile drive axle, relates in particular to a kind of 16 tonnes dual-ratio reduction rear-axle drive bridge.
Background technology
In, heavy truck vehicle is widely used in engineering transportation and logistics transportation, and its load-carrying capacity and carrying capacity very major part be to depend on drive axle.On 16 tonnes of drive axles, adopt the product that the dual-ratio reduction drive axle is arranged at present, but present 16 tonnes of dual-ratio reduction drive axles, be to adopt to dash the axle housing that weldering forms, cause can not adapt to domestic carrying capacity fully and cracking phenomena often appears in condition of road surface, so just makes that the crossing ability that 16 tonnes of dual-ratio reduction drive axle trucies are installed is relatively poor and load-carrying capacity is not high.
The utility model content
The utility model is at the deficiencies in the prior art, and it is good to have designed and developed out a kind of crossing ability, and torque capacity reaches 16 tonnes of high dual-ratio reduction drive axles of load-carrying capacity more greatly.
The utility model is achieved through the following technical solutions:
A kind of dual-ratio reduction jackshaft drive axle includes axle housing, final drive casing, connecting panel, fixed bearing, leaf spring pad pressing plate, shift sleeve, and brake assembly, semiaxis, differential assembly and the main gearbox assembly that links to each other with axle housing are installed in the axle housing; Gap bridge case lid, gap bridge case, center cross, planetary wheel, axle side gear, intermeshing driving gear and ring gear are arranged in the main gearbox assembly; The both sides of drive axle are brake wheels, are provided with wheel reduction gear in the wheel limit part in the described brake wheel outside; Wheel reduction gear is made of sun wheel, satellite gear and pinion carrier; Sun wheel is installed on the semiaxis, and satellite gear is installed on the pinion carrier, and sun wheel and satellite gear are meshing with each other.
A kind of dual-ratio reduction jackshaft drive axle is provided with the shaft space difference speed lock in the described final drive casing, the shaft space difference speed lock is meshed with shift sleeve; Built-in differential locking-device between wheel is housed on the gap bridge case, and built-in differential locking-device is fixedly mounted on the boss of gap bridge case lid between wheel.
A kind of dual-ratio reduction jackshaft drive axle, described axle housing is the inblock cast axle housing, axle housing stage casing, connecting panel, fixed bearing and leaf spring pad pressing plate are the Integratively casting.
A kind of dual-ratio reduction jackshaft drive axle, the internal diameter of described brake wheel is 410mm, external diameter is 470mm.
A kind of dual-ratio reduction jackshaft drive axle, described drive axle wheelspan is 1865mm, leaf spring width between centers 1040mm.
A kind of dual-ratio reduction jackshaft drive axle, the distance of the centre distance bottom of described drive axle axle housing is 192mm.
Axle housing of the present utility model is a cast structure, good rigidly, and load-carrying capacity is big, and axle housing is indeformable, and the gap bridge box structure is simple, compact dimensions.Interaxle differential is arranged in the back of cylindrical wheel, makes interaxle differential near ring gear like this, has improved the lubricating condition of interaxle differential; The between centers position of interaxle differential axial location and driving gear coincides simultaneously, thereby has shortened the axial dimension and the quality of gap bridge case greatly, and the support stiffness of cylindrical wheel is good, thereby width between centers is less, compact conformation.Eliminated the sintering fault that interaxle differential causes because of insufficient lubrication, differential locking-device is simple in structure, and assembly manipulation is simple, and actv. has prevented rate of breakdown.
