Description
Described technical field
The utility model relates to the heavy-duty truck double drive axle.
Background technology
The multi-axle heavy type goods carrying vehicle generally needs double drive axle, and it is composed in series by jackshaft and back axle.Existing 13 tons of duplex bridges adopt dual-ratio reduction more, have that complex structure, driving efficiency are low, poor reliability, a maintenance difficulty and be unfavorable for weak point such as environmental protection.
Summary of the invention
The purpose of this utility model, exactly in order to overcome above shortcoming, provide a kind of load-carrying capacity height, simple in structure, cost is low, light weight, fuel-efficient, the maintenance simple through single-stage deceleration double drive axle.
The utility model is achieved in that
Heavy motor vehicle double drive axle of the present utility model is made up of interaxle differential, jackshaft main reduction gear, rear-end gear reduction, inter-wheel differential, drg, axle housing, and main reduction gear is that single-stage is slowed down; The jackshaft final drive casing is an integral structure.Driving and driven gear is a Gleason system double curved surface finishing bevel gear cuter, and the axis of the relative driven wheel of differential of axis of drive bevel gear is skew 30-60mm down, and most preferred departure distance down is 44.45mm.
Heavy motor vehicle double drive axle of the present utility model, the preferred structure of its diff are the floating type diff of planetary wheel.
Heavy motor vehicle double drive axle of the present utility model, the preferred structure of its drg is: camshaft of brakes is the finish forge manufacturing, head avoids processing; Brake shoe brake cheek is welded by the steel plate punching press; Braking frictional plate adopts non-uniform thickness Friction disk.
Heavy motor vehicle double drive axle of the present utility model, axle housing is welded by the punching press of steel metal plate; Bearing adopts oil lubrication; Oil sealing adopts three lip oil sealings.
Through retarder of the present utility model adopts single-stage to slow down, and the jackshaft reducing gearbox adopts integral structure, has the advantage that rigidity is big, in light weight, simple and compact for structure, axial distance is short; Main driven gear adopts the Gleason double curved surface finishing bevel gear cuter of particular design, increased flank of tooth contact, have during work and more tooth is contacted simultaneously, running steadily, gear is powerful, and noise is little, and the life-span is long, the axis of the relative driven wheel of differential of axis of drive bevel gear is skew 44.45mm down, and vehicle body and whole center of gravity are reduced; Differential pinion gear and axle side gear are the finish forge manufacturing, and intensity is big, and be shock-resistant; The floating type diff of planetary wheel need not adjusted during assembling; On interaxle differential, be provided with differential locking-device, improved the carrying capacity on bad road surface; Axle housing is welded by the steel plate punching press, and the leaf spring section is of a size of 150*130mm; Brake-toggle shaft is the finish forge manufacturing, and head avoids processing; Brake shoe brake cheek adopts steel plate punching press welded structure, and is simple in structure; Braking frictional plate adopts non-grade for thick structure; Prolonged service life; All bearings all adopt oil lubrication; Oil sealing adopts three lip oil sealings, seals more reliable; The vehicle bridge ratio coverage is wide, and 18 kinds of speed ratios can be provided in the ratio coverage of 2.80-7.17; The vehicle bridge life-span uses proof can reach 1,000,000 kilometers through reality.
During use, power is given jackshaft and back axle from the input of jackshaft input end through the interaxle differential mean allocation, and back axle main reduction gear and inter-wheel differential separately passed to semiaxis in the warp again, reaches the wheel hub of drive wheels at last by the flange of semiaxis outer end.
Therefore, the utlity model has the load-carrying capacity height, simple in structure, cost is low, light weight, fuel-efficient, the maintenance simple through single-stage deceleration double drive axle.
