Abstract
The utility model provides a drive axle with special transmission ratio used in internal combustion tractor, wherein, a main shaft is provided with a driving spiral bevel gear, and a driven shaft is provided with two symmetrical driven spiral bevel gears with the same size. The driving spiral bevel gear of the driving shaft drives the driven spiral bevel gears at both sides to rotate, and the teeth ratio of the driving spiral bevel gear to the driven spiral bevel gears i is 5/47 and the modulus m is 7.5. Without changing the shape and size of the original axle, the utility model changes the transmission ratio of original drive axle from 1:6.67 to a single-stage transmission ratio 1:9.4 by improving the teeth ratio of a spiral bevel gear, so as to adapt to the speed ratio of imported gearbox. The utility model greatly reduces cost of the whole axle and has a certain price advantage.
Description
Technical field:
The utility model relates to the specific use towing vehicle, particularly relates to the ransaxle of the automobile-used special velocity ratio of a kind of diesel traction.
Technical background: the automobile-used gearbox of diesel traction of specific use all is import at present, and existing drive axle ratio is 1: 6.67, and the velocity ratio of this type of ransaxle is more rare in existing tractor industry, and difficulty of processing is big.The transmission system of ransaxle is an easily damaged parts, not only costs an arm and a leg, and will spend a large amount of foreign exchanges.
Summary of the invention:
The purpose of this utility model is exactly the ransaxle that the automobile-used special velocity ratio of a kind of diesel traction will be provided, and it is 1: 9.4 that 1: 6.67 speed ratio of original drive axle ratio is improved to single staged transmission ratio, adapts to the speed ratio of import gearbox.The purpose of this utility model is to realize like this, the ransaxle of the automobile-used special velocity ratio of a kind of diesel traction, it is characterized in that: main shaft is provided with initiatively helical bevel gear, driven shaft is provided with two identical driven helical bevel gears of symmetry size, the initiatively driven helical bevel gear rotation of helical bevel gear drive both sides on the driving shaft, the gear ratio of described active helical bevel gear and driven helical bevel gear is i=5/47, modulus m=7.5.The utility model improves the gear ratio of spiral bevel gear under the prerequisite of the boundary dimension that does not change original pontic, can significantly reduce the cost of whole bridge, and certain price advantage is arranged.
Description of drawings:
Fig. 1 is the utility model structural representation;
1. helical bevel gear initiatively, 2. main shaft, 3. driven helical bevel gear, 4. driven shaft.
Embodiment;
The utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, the ransaxle of the automobile-used special velocity ratio of a kind of diesel traction of the utility model, formed by main shaft 2, active helical bevel gear 1, driven helical bevel gear 3, it is characterized in that: main shaft 2 is provided with initiatively helical bevel gear 1, driven shaft 4 is provided with two identical driven helical bevel gears 3 of symmetry size, initiatively driven helical bevel gear 3 rotations of helical bevel gear 1 drive both sides on the main shaft 2, the gear ratio of described active helical bevel gear 1 and driven helical bevel gear 3 is i=5/47, modulus m=7.5.During concrete enforcement, under the prerequisite of the boundary dimension that does not change original pontic, improve the gear ratio of spiral bevel gear, change the gear ratio of active helical bevel gear on the driving shaft and the driven helical bevel gear on the driven shaft into i=5/47, modulus m=7.5, reaching single staged transmission ratio is 1: 9.4, adapts to the speed ratio of import gearbox.
