Abstract
The utility model discloses a kind of 17 tons of steering drive axles: comprise axle housing, main reduction gear, wheel reduction gear, spindle nose, semiaxis, wheel hub, brake disc; Described main reduction gear comprises diff, this steering drive axle is also provided with steering swivel, described axle housing is resulting by nodular cast iron inblock cast, main reduction gear is installed on axle housing middle part, steering swivel is installed on the two ends of axle housing, spindle nose and brake disc are fixedly mounted on steering swivel, wheel hub utilizes the inside and outside bearing of wheel hub that wheel hub is arranged on spindle nose, wheel reduction gear is arranged on wheel hub, one end of semiaxis is connected with the axle side gear of main reduction gear, and the other end of semiaxis is connected with the sun gear of wheel reduction gear.The utility model reasonable in design, is used spheroidal graphite iron integrally casting to go out axle housing, at the semiaxis two ends of drive axle, increases steering swivel, has realized the turning function of drive axle.
Description
Technical field
The utility model relates to automotive field, particularly a kind of 17 tons of steering drive axles of large-scale working truck.
Background technology
Drive axle is the necessary structure of travelling of vehicle, and drive axle is comprised of main reduction gear, diff, semiaxis and axle housing.Its effect is that the motor torque that driving device is transmitted passes to driving wheel by main reduction gear, diff, semiaxis etc., realizes reduction of speed and increases torque: the direction of transfer that changes torque by main reduction gear taper gear pair; By diff, realize both sides wheel differential action, guarantee that medial and lateral wheel turns to different rotating speeds.Existing many drive axles, due to self insufficient strength, can not be used on large-scale working truck, and can not carry out double reduction, and general drive axle can only be responsible for the driving to vehicle, and can not turn to vehicle.
Utility model content
The purpose of this utility model be to provide a kind of can be for large-scale working truck, there is stronger rigidity, the drive axle that integrates driving, turns to that bearing load is larger.
The technical solution of the utility model is: a kind of 17 tons of steering drive axles: comprise axle housing, main reduction gear, wheel reduction gear, spindle nose, semiaxis, wheel hub, brake disc; Described main reduction gear comprises diff, this steering drive axle is also provided with steering swivel, described axle housing is resulting by nodular cast iron inblock cast, main reduction gear is installed on axle housing middle part, steering swivel is installed on the two ends of axle housing, spindle nose and brake disc are fixedly mounted on steering swivel, wheel hub utilizes the inside and outside bearing of wheel hub that wheel hub is arranged on spindle nose, wheel reduction gear is arranged on wheel hub, one end of semiaxis is connected with the axle side gear of main reduction gear, and the other end of semiaxis is connected with the sun gear of wheel reduction gear.
Described main reduction gear and wheel reduction gear are epicyclic type device.
Described steering swivel adopts the manufacture of austempered ductile iron material.
The beneficial effects of the utility model are:
The utility model reasonable in design, is used spheroidal graphite iron integrally casting to go out axle housing, and the wall thickness of thickening axle housing, makes axle housing have higher rigidity and intensity, can carry heavier heavy burden.Semiaxis two ends at drive axle increase steering swivel, have realized the turning function of drive axle.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of steering drive axle.
Fig. 2 is the main reduction gear constructional drawing of steering drive axle.
Fig. 3 is the wheel limit assembly structure schematic diagram of steering drive axle.
The specific embodiment
According to Fig. 1 to Fig. 3, embodiment 1 is elaborated, a kind of 17 tons of steering drive axles: comprise axle housing 11, main reduction gear 15, diff 16, wheel hub 18, semiaxis 21, spindle nose 22, wheel reduction gear 14, brake disc 13 and steering swivel 12; Described main reduction gear and wheel reduction gear are epicyclic type device, and this steering drive axle possesses simultaneously and turns to and drive function, and axle housing 11 is used Unitary ductile irons, and steering swivel 12 adopts the manufacture of austempered ductile iron materials; Main reduction gear 15 is installed on axle housing 11 middle parts, steering swivel 12 is installed on the two ends of axle housing 11, spindle nose 22 and brake disc 13 are fixedly mounted on steering swivel 12, wheel hub 18 is arranged on spindle nose 22, wheel reduction gear 14 is arranged on wheel hub 18, one end of semiaxis 21 is connected with the axle side gear of main reduction gear 15, the other end of semiaxis 21 is connected with the sun gear of wheel reduction gear 15, on brake disc 13, be also provided with a hydraulic brake caliper 32, hydraulic brake caliper 32 is braked brake disc 13 by fluid control.
Main reduction gear 15 active and passive gears 51 adopt hypoid conical gear, engagement, transmission is reasonable, housing adopts thickening type casting, rigidity and the aseismicity of housing have greatly been improved, gear all adopts carburizing and quenching to process, and obtains high hard wearing face, whole roll flutes after gear heat treatment, reduce noise, improved efficiency and the service life of complete machine.Therefore there is the features such as lightweight, volume is little, gear range is large, efficiency is high, smooth running, the low strong adaptability of noise.
Claims (3)
1. 17 tons of steering drive axles: comprise axle housing, main reduction gear, wheel reduction gear, spindle nose, semiaxis, wheel hub, brake disc; Described main reduction gear comprises diff, it is characterized in that: this steering drive axle is also provided with steering swivel, described axle housing is resulting by nodular cast iron inblock cast, main reduction gear is installed on axle housing middle part, steering swivel is installed on the two ends of axle housing, spindle nose and brake disc are fixedly mounted on steering swivel, wheel hub utilizes the inside and outside bearing of wheel hub that wheel hub is arranged on spindle nose, wheel reduction gear is arranged on wheel hub, one end of semiaxis is connected with the axle side gear of main reduction gear, and the other end of semiaxis is connected with the sun gear of wheel reduction gear.
