Abstract
The utility model relates to a special wheel reducer for a heavy truck, an off-road vehicle or a large bus, comprising a framework, a wheel input shaft, a wheel supporting shaft, a gear ring, a planet carrier, a planet pinion shaft, a planet gear, a sun gear, a hub and a brake disc. The gear ring is connected with the spline of the hub; the planet gear is mounted on the planet carrier by the planet pinion shaft; the planet carrier is integrated with the spline of the wheel supporting shaft; and the planet gear meshes with the gear ring. The sun gear matches with and is connected with the wheel input shaft by the spline and meshes with the planet gear. The utility model adopts the planet transmission mode; therefore, the utility model has the advantages of compact structure and large transmission ratio. The size of a primary reducer in a driving axle can be reduced and enough ground clearance can be ensured; the large total transmission ratio of the driving axle can be obtained; the transmission ratio is larger so the output torque of the wheel reducer is increased; the driving force of a driving wheel is increased and the power requirement of heavy automobile can be satisfied; use cost is low; and transmission strength is high and transmission stability is good.
Description
Technical field
The utility model is a kind of novel wheel reduction gear that is used for heavy wrecker truck, cross-country car or motor omnibus.
Background technology
Traditional planetary wheel wheel reduction gear is made up of gear ring, gear ring base, planetary wheel, planetary frame and sun gear etc., and the sun gear of wheel reduction gear connects with the semiaxis of vehicle bridge with spline, rotates with semiaxis.Gear ring connects with gear ring base, also uses retainer ring spacing, and gear ring base connects with axle tube (being equivalent to hub carrier) with spline and fix its axial location with jam nut, thereby can not rotate.A plurality of planetary wheels are housed between sun gear and gear ring.Planetary wheel is to be bearing on the planetary frame by its compensating-gear shaft and needle roller.Planetary frame connects with wheel hub with bolt.The power of diff output is promptly passed to wheel hub and is made the drive wheels rotation through sun gear, planetary wheel, planetary frame etc. from semiaxis.Wherein sun gear is a driving link, and planetary frame is a driven member, and gear ring maintains static, and its strength of gear teeth is the intensity maximum when transmitting ratio i ≈ 4.Wheel reduction gear at some demand i ≈-3, half that planetary diameter is approximately sun gear will appear by this structure design, for guaranteeing planetary wheel spider gear shaft and intensity are installed, planetary wheel just can not design very for a short time, will add the volume and weight of large sun gear and whole wheel reduction gear like this, cost is higher.
Summary of the invention
In order to overcome the deficiency of above existing planetary wheel wheel reduction gear, the utility model provides the extraordinary wheel reduction gear of a kind of strength of gear teeth intensity maximum when transmitting ratio i ≈ 3, this wheel reduction gear compact conformation, load-carrying capacity are strong, speed ratio i ≈ 3 can satisfy low cost, the high strength requirement of heavy motor vehicle with wheel reduction gear.
The utility model is that the technical scheme that the technical solution problem is adopted is:
Extraordinary wheel reduction gear includes gear ring, wheel hub, hub carrier, wheel limit input shaft, planetary wheel, planet axis, sun gear, pinion carrier, end cap, framework and brake disc.The dress needle bearing is assemblied on the pinion carrier by planet axis and thrust washer in the described planetary wheel, and pinion carrier and hub carrier splined are one, and with jam nut, retaining washer, first and second bearings and spacer axial compression; Described gear ring splined on the flange of wheel hub, and with the boss that is connected the framework on the wheel hub with the gear ring axial limiting, wheel hub by first and second bearings on pinion carrier and hub carrier; The sun gear spline is connected on the input shaft of wheel limit, and meshes with planetary wheel.
The utility model wheel reduction gear has adopted a planet gear mechanism, gear ring directly and wheel hub link, the pinion carrier that planetary wheel, planet axis are housed is connected as one with spline and hub carrier and maintains static, wheel limit input shaft is that the power that transmits of semiaxis is through sun gear, planetary wheel, gear ring is directly passed to wheel hub, drives wheel by the wheel attachment bolt.Wherein sun gear is a driving link, and gear ring is a driven member, and pinion carrier maintains static.This novel wheel reduction gear does not have gear ring pallet, planetary frame end cap, and the pinion carrier volume is less, and framework is transferring power not, can do more frivolously, and cost is lower.According to the characteristics of this NGW type planetary transmission, the transmitting ratio i=gear ring number of teeth/sun wheel number of teeth during fixed gear ring, calculate by number of teeth condition and the strength of gear teeth again and know: i=-3 during the gear ring number of teeth/3=sun wheel number of teeth=satellite gear number of teeth, and intensity is best under the same terms.
Therefore, the increase of this wheel reduction gear transmitting ratio makes that the main reduction gear size reduces in the drive axle, has guaranteed enough ground Clearances, and can obtain bigger drive axle overall gear ratio; Because semiaxis is before wheel reduction gear, so the moment of torsion that bears greatly reduces, thereby accessory sizes such as semiaxis and diff can reduce; Transmitting ratio increases increases the torque of this wheel reduction gear output, and the propulsive effort of drive wheel is strengthened.Therefore, the utlity model has that compact conformation, transmitting ratio are big, the characteristics of easy-maintaining, satisfied the requirement of heavy motor vehicle dynamic property.
