Abstract
The invention provides a mine double-stage deceleration drive axle of a heavy-duty car. Under the conditions that weight is not added and existing drive axle space is not changed, a main speed reducer and a wheel-side speed reducer are optimized, the speed ratio of a whole axle is reallocated, in the bevel gear space of the existing main speed reducer, and the final drive ratio is 3-4; in the space of the existing drive axle wheel-side speed reducer, a planetary mechanism of the wheel-side speed reducer is a four-planetary-wheel mechanism, and the wheel-side speed ratio is 4-5; the overall speed ratio of the whole axle reaches 14-17, after a whole car is matched with an automatic transmission, compared with a manual transmission, after the transmission speed ratio is reduced greatly, the driving force of the car can still be kept to be almost the same, and the performance requirements of the whole car are met.
Description
technical field
The present invention relates to a kind of mining dual-ratio reduction drive axle of heavy motor vehicle.
background technology
Owing to being subject to the restriction of space and own wt, the wheel limit speed ratio of the mining dual-ratio reduction drive axle of domestic heavy motor vehicle must be less than 4, cause whole bridge overall ratio relatively little, the Manual transmission that can only mate large speed ratio, cannot meet the demand of mating Automatic Transmission vehicle performance.
summary of the invention
The technical problem to be solved in the present invention is to provide a kind of mining dual-ratio reduction drive axle of heavy motor vehicle, and whole axle ratio increases, and can mate Automatic Transmission.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A mining dual-ratio reduction drive axle for heavy motor vehicle, comprises main reduction gear and wheel reduction gear, and base ratio is 3-4, and wheel limit speed ratio is 4-5, and whole bridge overall ratio is 14-17.
The mining dual-ratio reduction drive axle of above-mentioned heavy motor vehicle, the gear pair of main reduction gear adopts Ao Likang gear processed.
The mining dual-ratio reduction drive axle of above-mentioned heavy motor vehicle, the planetary mechanism of wheel reduction gear adopts 4 planetary wheeling mechanisms.
The present invention is adjusted into 3-4 by base ratio, and wheel limit speed ratio rises to 4-5, and whole bridge overall ratio rises to 14-17, after car load coupling Automatic Transmission, compare with Manual transmission, after change speed gear box speed ratio significantly reduces, still can keep vehicle drive force suitable, guarantee the performance requriements of car load.Planetary mechanism adopts 4 planetary wheeling mechanisms, compares with existing 5 planetary wheeling mechanisms, reduces or does not gain in weight.
accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in more detail:
Fig. 1 is structural representation of the present invention.
In figure: 1 main reduction gear, 2 wheel reduction gears.
The specific embodiment
As shown in Figure 1, the mining dual-ratio reduction drive axle of heavy motor vehicle comprises main reduction gear 1 and wheel reduction gear 2.Do not gaining in weight and do not changing under the big frame in existing drive axle space, optimize main reduction gear and wheel reduction gear, whole axle ratio is redistributed, in existing main reduction gear finishing bevel gear cuter space, the gear pair of main reduction gear adopts Ao Likang gear processed, improved Driven Gear of Final Reduction Gear intensity, base ratio is 3-4; In existing drive axle wheel side reducer space, the planetary mechanism of wheel reduction gear adopts 4 planetary wheeling mechanisms, and wheel limit speed ratio is 4-5; Whole bridge overall ratio reaches 14-17, after car load coupling Automatic Transmission, compares with Manual transmission, after change speed gear box speed ratio significantly reduces, still can keep vehicle drive force suitable, has guaranteed the performance requriements of car load.
