Abstract
The utility model relates to a double-reduction back axle pusher axle. A hub reducer is arranged in a hub part on the outer of a brake drum; the hub reducer consists of a sun wheel, a planet wheel and a planet carrier, wherein, the sun wheel is arranged on a semiaxle, the planet wheel is arranged on the planet carrier and the sun wheel is meshed with the planet wheel. A differential lock is arranged in a main reducer case and is meshed with a meshing cover. An axle housing is a piece of integral casting. A midpiece of the axle housing, a connector panel, a fixed support and a plate spring gasketed plate are all integral cast. The axle housing of the utility model has casting structure, good rigidity, big carrying capacity, nondeforming axle housing and simple structure. The main reducer is provided with the differential lock and is of convenience for assembly and operation and reduction of machine drive and 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 rear-axle drive bridge includes axle housing, 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; Center cross, planetary wheel, axle side gear, intermeshing driving gear and ring gear are arranged in the main deceleration 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 rear-axle drive bridge, described master subtracts and is provided with differential locking-device in the shell; Differential locking-device is meshed with shift sleeve.
A kind of dual-ratio reduction rear-axle drive bridge, 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 rear-axle drive bridge, the internal diameter of described brake wheel is 410mm, external diameter is 470mm.
A kind of dual-ratio reduction rear-axle drive bridge, described drive axle wheelspan is 1865mm, leaf spring width between centers 1040mm.
A kind of dual-ratio reduction rear-axle drive bridge, the distance of the centre distance bottom of described drive axle axle housing is 192mm.
The utility model axle housing is a cast structure, good rigidly, and load-carrying capacity is big, and axle housing is indeformable, and is simple in structure, and the axle housing stage casing is gone in spindle nose hot pressing, and right alignment is good.The built-in differential locking-device of main reduction gear band of this utility model bridge, assembly manipulation is convenient, and has reduced mechanical drive, reduces rate of breakdown.
