The purpose of this utility model is achieved in that this drive axle is dual-ratio reduction, and namely main reduction gear and wheel reduction gear comprise wheel reduction gear, drg, main reduction gear and axle case assy; Axle case assy is connected with main reduction gear, is connected with respectively drg and wheel reduction gear in two sides of main reduction gear; Main reduction gear by accurate Double curve screw bevel-gear pair transmitting torque to semiaxis; Wheel reduction gear is four lines star wheel structure planetary reduction gear, and inner gear is captiveed joint with axle housing end axle by spline, and sun wheel is floated and passed through spline joint with semiaxis, and wheel reduction gear power is delivered to sun wheel, satellite gear by semiaxis, exports by planetary wheel carrier; Drg is caliper disk brake, is contained between hub reduction and the axle housing.
Described satellite gear comprises steel ball, planet wheel spindle, planetary wheel carrier, satellite gear, pad, satellite gear spacer and needle roller, and on planetary wheel carrier, the satellite gear two sides are placed with pad to satellite gear by planet wheel spindle and needle roller support, and the needle roller both sides are placed with spacer; Be drilled with some oilholes on each satellite gear cylindrical, be used for lubricating effect; Have keyway on the planet wheel spindle, half slot is arranged on the planetary wheel carrier, be used for placing steel ball; The effect of steel ball is to stop relatively rotating of planet wheel spindle and planetary wheel carrier.
Beneficial effect, owing to adopted such scheme, this drive axle adopts dual-ratio reduction, main gear is the autotruck main reduction gear, by the stronger accurate Double curve screw bevel-gear pair transmitting torque of load-carrying capacity; Wheel reduction gear adopts heavier-duty spur wheel NGW planet circular system structure, replaces former three planetary gear structures with the four lines star-wheel, in the situation that connection dimension is constant outside, has effectively strengthened the load-carrying capacity of wheel reduction gear; Drg adopts the preferably caliper disk brake replacement shoe brake that dispels the heat, and brakes reliable, easy to maintenance; Satisfied low speed, heavy duty, high pulling torque, braking is reliable, and the gear that has solved drive axle is beaten tooth, is braked insecure problem.Efficiently solve the driving axle of forklift gear and beat tooth, brake insecure problem, reach the purpose of this utility model.
Advantage:
1, the drive axle wheel side reducer adopts heavier-duty NGW planet circular system structure, substitutes three planetary gear structures with the four lines star-wheel; Effectively strengthen the load-carrying capacity of drive axle in the situation that connection dimension is constant outside, improved the functional reliability of drive axle.
2, main reducing gear of drive axle adopts the autotruck main reduction gear, and accurate Double curve screw bevel-gear pair transmitting torque is large.
3, drg adopts caliper disk brake to substitute shoe brake, brakes reliable, easy to maintenance.
4, drive axle structure is advanced, reasonable, is convenient to processing, assembling, has reduced manufacturing cost.
