Abstract
The utility model relates to an automatic charging electric vehicle speed increase unit, including box, power input shaft, power output shaft, the pinion carrier put the tip at power output shaft, the driven gear cover is put at the power output shaft tip that sets up with the power input shaft level, be provided with on the box and support with location power input shaft and power output shaft respectively and can make its first bearing and second bearing that freely moves along the axis direction, the oil filler point that have lubricated driving gear and driven gear is opened at the box top. The utility model discloses power input shaft and power output shaft have adopted and to have made its bearing along the axis direction removes support, make speed increase unit can be applied to more operating modes. The charging electric vehicle's of this automation simultaneously speed increase unit has adopted easy processing of straight -tooth roller gear meshing and efficiency higher.
Description
Technical field
The utility model relates to speed variator for automobile field, particularly relates to a kind of automatic charging electric vehicle boost installation.
Background technology
Present battery-driven car more and more receives an acclaim, and especially automatic charging electric vehicle is subject to the favor of people especially.In the technology of existing automatic charging, be all generally by gravitional force during descending or unnecessary kinetic energy are driven electrical power generators, thus realize the function of automatic charging.
But present automatic charging electric vehicle is due to the problem such as design of structure, and energy conversion efficiency is very low.If optimize the structure of battery-driven car, the energy conversion efficiency of battery-driven car will improve, thus also can improve the flying power of battery-driven car.
Summary of the invention
The utility model, for the shortcoming of above-mentioned technical matters, provides a kind of structure simple, the boost installation of the convenient a kind of automatic charging electric vehicle installed.
For achieving the above object, the technical solution of the utility model is:
A kind of automatic charging electric vehicle boost installation, comprise casing, power input shaft, power take-off shaft, described driving gear is nested with at Power output shaft end, and driven gear is nested with at Power output shaft end horizontally disposed with power input shaft; Casing is provided with support respectively and positioning power input shaft and power take-off shaft and its clutch shaft bearing moved freely in the axial direction and the second bearing can be made; The oil hole of lubrication driving gear and driven gear is had at casing top.
Preferably, described driving gear is all connected by key with power take-off shaft with power input shaft, driven gear.
Preferably, driving gear and driven gear are spur wheel engagement, and the ratio of rotating speed is 1:2.
After adopting technique scheme, the beneficial effects of the utility model are:
Because the power input shaft of boost installation connects electrical motor by power-transfer clutch, so power input shaft and power take-off shaft all have employed the bearings that can make its movement in the axial direction, make boost installation can be applied to more operating mode.Simultaneously the boost installation of this automatic charging electric vehicle have employed spur wheel engagement be easy to processing and efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the constructional drawing of a kind of automatic charging electric vehicle boost installation of the utility model.
In figure: 1 casing, 2 power input shafts, 3 power take-off shafts, 4 driving gears, 5 driven gears, 6 lubricating oil oil holes, 7 clutch shaft bearings, 8 second bearings, 9 keyways.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of automatic charging electric vehicle boost installation, comprises casing 1, power input shaft 2, power take-off shaft 3, driving gear 4, driven gear 5, lubricating oil oil hole 6, clutch shaft bearing 7, the second bearing 8, keyway 9.Described power input shaft and power take-off shaft are supported by clutch shaft bearing 7 and the second bearing 8 respectively and locate and all can move freely in the axial direction; Between driving gear and power input shaft, between driven gear and power take-off shaft, be provided with keyway 9; Driving gear and driven gear are spur wheel engagement, and the ratio of rotating speed is 1:2; The oil hole 6 that can inject lubricating oil is provided with at casing top.
Common gear case carries out improving designing by a kind of automatic charging electric vehicle boost installation described in the utility model; The input end of the power input shaft of described boost installation connects electrical motor by power-transfer clutch, the mouth sending and receiving motor of power take-off shaft.Driven the driven gear 5 on power take-off shaft 3 by the driving gear 4 on power input shaft 2, driven gear 5 drives power take-off shaft 4, for electrical generator provides power; When the power-transfer clutch opening and closing that power intake connects, the power input shaft 4 of described boost installation and power take-off shaft 5 can realize moving along its axis under the support of clutch shaft bearing 7 and the second bearing 8.
