Abstract
The utility model discloses an automobile dual-output speed changing gear, which comprises a gear shaft and dual-output speed changing gears, wherein the dual-output speed changing gears are sheathed on the gear shaft, a needle rolling bearing is arranged between the dual-output speed changing gears and the gear shaft, the dual-output speed changing gears are two gears with different diameters, the two gears are coaxial and are processed into a whole, and a braking plate used for preventing the dual-output speed changing gears and a gearbox casing from generating axial jumping is arranged on the gear shaft. In order to improve the stability and the effect of the braking plate for preventing the dual-output speed changing gears from generating jumping, the braking plate is a bulge which is processed on the gear shaft and has the diameter greater than that of the gear shaft. In order to enable the braking plate not to interfere with the rotation of the dual-output speed changing gears on the gear shaft, the braking plate is propped on an inner ring of a bearing.
Description
Technical field
The utility model relates to auto parts and components, particularly relates to automobile double output variable speed gear.
Background technique
In the prior art, dual output speed change gear and gear shaft are structure as a whole, in gearbox, with respect to gear box casing, rotate, dual output speed change gear is two gears that diameter differs, and this two gear makes automobile produce different gait of march while working separately.Because needs dual output speed change gear rotates with respect to gear box casing, therefore between gear shaft and gear box casing, adopt the needle bearing with outer ring to carry out radial location, adopt clamping stopper bearing to carry out axially locating.During assembling, need first press-fit the needle bearing of band outer ring, two ends, refill and join thrust bearing, last assembling gear assembly.
Dual output speed change gear two needle bearings with outer ring of needs and two clamping stopper bearings due to this structure, cost is high on the one hand, between gear box casing and gear shaft, need to press-fit the needle bearing with outer ring, high to gear box casing housing bore and gear shaft requirement on machining accuracy, and need press-fit with the needle bearing of outer ring, assembling is complicated, reprocesses difficulty large; On the other hand, whole gear shaft and himself subsidiary dual output speed change gear together rotate, and the energy needing is larger, is also unfavorable for reducing the oil consumption of automobile.
Model utility content
For the problems referred to above, the utility model provides automobile double output variable speed gear, and it is simple in structure, easily assembling and can effectively reduce oil consumption.
The technological scheme that the utility model is taked is:
Automobile double output variable speed gear, comprises gear shaft and dual output speed change gear, and dual output speed change gear is sleeved on gear shaft, between described dual output speed change gear and gear shaft, bearing is installed; Described dual output speed change gear is the gears that two diameters do not wait, and two gears are coaxial and be processed as one; Described gear shaft is provided with the check plate that stops dual output speed change gear generation axial float.
For further improving the operational efficiency of bearing, described bearing is needle bearing.
For improving the effect and the stability that prevent dual output speed change gear generation play of check plate, described check plate is the projection that the diameter that processes on gear shaft is greater than gear shaft.
For making not interfere the rotation of dual output speed change gear on gear shaft, described check plate withstands on the interior ring of bearing.
Because the utility model has adopted technique scheme, two needle bearings with outer ring and two clamping stopper bearings have not only been saved, also reduced the machining accuracy demand of gear shaft end, also reduced simultaneously rotatable parts quality, reduced the friction area between bearing and gear shaft, thereby played the effect that reduces oil consumption.
Accompanying drawing explanation
Fig. 1 is the structural drawing of automobile double output variable speed gear in prior art.
Fig. 2 is the structural representation of the utility model automobile double output variable speed gear.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described, in illustrative examples and the explanation of this model utility, is used for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 1, the automobile double output variable speed gear of prior art is by gear shaft 1, gear box casing 2, form with needle bearing 3 and the clamping stopper bearing 4 of outer ring, gear shaft 1 is provided with dual output speed change gear 5, gear shaft 1 drives dual output speed change gear 5 to rotate with respect to gear box casing 2, between gear shaft 1 and gear box casing 2, adopt the needle bearing 3 with outer ring to carry out radial location, adopt clamping stopper bearing 4 to carry out axially locating.Its complex structure, cost are high, to having relatively high expectations of the endoporus of gear box casing 2 and gear shaft 1 machining accuracy, and complicated with needle bearing 3 handling of outer ring, to reprocess difficulty large; And whole gear shaft 1 and himself subsidiary dual output speed change gear 5 together rotate, and the friction area between each bearing is also large, the energy needing is larger, is also unfavorable for reducing the oil consumption of automobile.
As shown in Figure 2, automobile double output variable speed gear of the present utility model comprises gear shaft 1 and dual output speed change gear 5, and dual output speed change gear 5 is sleeved on gear shaft 1, between dual output speed change gear 5 and gear shaft 1, needle bearing 6 is installed.Described dual output speed change gear 5 is the gears that two diameters do not wait, and two gears are coaxial and be processed as one; Described gear shaft 1 is provided with the check plate 11 that stops dual output speed change gear 5 and gear box casing 2 that axial float occurs.For improving the dual output speed change gear 5 that prevents of check plate 11, effect and the stability of play occur, described check plate 11 is the projection that on gear shaft, 1 diameter processing is greater than gear shaft.For making check plate 11 not interfere the rotation of dual output speed change gear 5 on gear shaft 1, described check plate 11 withstands on the interior ring of bearing.
