Abstract

The utility model relates to a three-stage speed-reduction driving axle comprising a two-stage hub speed reducer, and the three-stage speed-reduction driving axle comprises a one-stage speed reducer and hub speed reducers, wherein the one-stage speed reducer is arranged on the centre of the driving axle; and the hub speed reducers are arranged on both ends of the driving axle. The three-stage speed-reduction driving axle is characterized in that the hub speed reducer is the two-stage hub speed reducer. The utility model has the advantages that the speed ratio of the three-stage speed-reduction driving axle can reach 20; and the output torque can reach two times than that of the driving axle of the existing heavy-duty car. Because the output torque of the gearbox is divided to three stages to load by the three-stage speed-reduction driving axle, the torque moment loaded by each stage of speed reduction is relatively small, the entire axle can obtain a greater output torque, and the utility model is suitable for special applications with low speed, heavy load, great torque moment, and the like.

Description

Three grades of deceleration bridges of band twin-stage wheel reduction gear
One: technical field
The utility model relates to a kind of three grades of deceleration bridges with the twin-stage wheel reduction gear.
Two: technical background
The heavy motor vehicle drive axle of existing belt wheel side reducer is the dual-ratio reduction structure, is made of single reduction final drive that is installed in drive axle central authorities and wheel limit single reduction gear.Because whole bridge has only double reduction, can't obtain the large speed ratio 10 or more, also just the amplification of change speed gear box output torque can't be outputed to wheel for 10 times, so the dual-ratio reduction bridge can't satisfy some particular application as part transportation greatly, mine dumping car etc.
Three: summary of the invention
The purpose of this utility model provides that a kind of speed ratio is big, moment of torsion is high, is applicable to three grades of deceleration bridges of the band twin-stage wheel reduction gear of low-speed heave-load occasion.
The purpose of this utility model realizes in the following manner:
The utility model comprises the single reduction gear that is installed in drive axle central authorities and is installed in the wheel reduction gear at drive axle two ends that it is characterized in that: wheel reduction gear is the dual-ratio reduction device.
The described limit dual-ratio reduction device of taking turns is made of bell hub, gear ring, one-level sun wheel, secondary sun wheel, one-level satellite gear, secondary planet wheel, planetary frame, planetary frame axle, one-level satellite gear, secondary planet wheel mesh with one-level sun wheel, secondary sun wheel respectively, and planetary frame axle and secondary sun wheel connect.
The utility model has the advantages that: the speed ratio of three grades of deceleration bridges can reach 20, and output torque can reach 2 times of existing heavy motor vehicle drive axle output torque.Triple-reduction axle is owing to divide three grades to bear the change speed gear box output torque, so the moment of torsion that each grade deceleration is born is little relatively, whole bridge can obtain bigger output torque, is fit to particular application such as low speed, heavy duty, high pulling torque.
Four: description of drawings:
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the structural representation of wheel limit dual-ratio reduction device.
Five: the specific embodiment:
With reference to accompanying drawing, the utility model comprises single reduction gear 3 that is installed in drive axle central authorities and the wheel reduction gear 2 that is installed in the drive axle two ends, and wheel reduction gear 2 is dual-ratio reduction devices.
Wheel limit dual-ratio reduction device 2 is made of bell hub 12, gear ring 6, one-level sun wheel 5, secondary sun wheel 9, one-level satellite gear 7, secondary planet wheel 10, planetary frame 11, planetary frame axle 8, one-level satellite gear 7, secondary planet wheel 10 mesh with one-level sun wheel 5, secondary sun wheel 9 respectively, and planetary frame axle 8 connects with secondary sun wheel 9.The principle of work of wheel limit dual-ratio reduction device 2 is as follows:
Semiaxis 4 drives one-level sun wheel 5, under the condition that gear ring 6 is fixed, by engagement one-level satellite gear 7, drive 8 rotations of planetary frame axle, planetary frame axle 8 is that gear ring 6 is fixing by connecting second stage sun wheel 9 equally, engagement secondary planet wheel 10, drive planetary frame 11, bell hub 12 and wheel hub 13 rotations, realized wheel limit dual-ratio reduction.
