Abstract
The utility model relates to a parallel connection ladder type automatic transmission case, which belongs to a transmission case of a vehicle. The utility model comprises a case body 9, a driving shaft 5 and a driven shaft 8. In four to six one stage planetary transmission structures which are connected in parallel, each sun wheel 4 is fixedly connected with the driving shaft 5 and a planetary frame 3 which is used as a driving wheel is rotationally connected with the driving shaft 5. An inner gear 6 is rotationally connected with the driving shaft 5, a clamping and fixing device 1 of the inner gear is fixedly connected with the case body 9. The outer edge of the planetary frame 3 is provided with a gear tooth which is engaged with the driven wheel 7 which is arranged on the driven shaft 8. The utility model has the advantages of novel structure and simple structure, makes use of the principle of the transmission of a planetary gear to achieve the purpose of changing speed through the combination of differential gears. All gears work in the state of full engagement, and adopts flexible mode for the transition of a high range and a low range. The utility model has the advantages of easy manufacture, convenient maintenance and flexible operation.
Description
Technical field
The utility model belongs to a kind of gearbox of vehicle.
Background technique
The automatic transmission of using on the automobile mainly is a principle of having utilized fluid moment now, its complex structure, and the production difficulty is big, and safeguarding needs the professional workforce, the cost height, oil consumption is big.
Summary of the invention
The utility model provides a kind of cascade automatic transmission case in parallel, with solve present automatic transmission structure complexity, the production difficulty is big, cost is high, the problem that oil consumption is big.The technological scheme that the utility model is taked is: comprise casing 9, driving shaft 5 and driven shaft 8, it is characterized in that: each sun gear 4 in 4～6 in parallel single-stage planetary drive mechanisms fixedlys connected with driving shaft 5, be rotationally connected as the planet carrier 3 and the driving shaft 5 of driving wheel, internal gear 6 is rotationally connected with driving shaft 5, internal gear clamping and fixing device 1 is fixedly connected on the casing 9, planet carrier 3 outer rims have the gear teeth, be meshed with the follower 7 on the driven shaft 8, all inequality as the gear ratio of each planet carrier of driving wheel and follower; In each single-stage planetary drive mechanism, be fixed on sun gear and planet wheel 2 engagements on the driving shaft, this planet wheel and planet carrier are rotationally connected, this planet wheel and internal gear 6 engagements.During work, the driving shaft rotation, all sun gears all rotate, and when all internal gears 6 all are not fixedly clamped by internal gear clamping and fixing device 1, are in the neutral state; When the clamped fixing device 1 of internal gear was fixedly clamped, as 1 retaining, planet wheel drove the planet carrier rotation, and planet carrier meshes follower as driving wheel, makes the driven shaft rotation; When the speed of a motor vehicle is elevated to when being fit to 2 grades, the internal gear clamping and fixing device 1 in 1 retaining is unclamped, make the internal gear clamping and fixing device in 2 retainings clamp internal gear simultaneously, at this moment the planet carrier on these 2 grades meshes follower as driving wheel, makes the driven shaft rotation; So repeat work, up to the most high-grade.
Advantage of the present utility model is: novel structure, simple, utilized the principle of planetary pinion transmission, and reach the purpose of speed change by the combination of different gears.All gears all are operated in full engagement, are flexible way during the high and low shift transition.The utility model manufacturing is simple, and is easy to maintenance, flexible operation.
