Abstract
A continuous variable transmission is provided that is based on gearwheels. The novel gear acts as efficient transmission that can replace conventional manually or automatics gears. The CVT comprises sun gear connected to input shaft and ring gear fixedly connected to output shaft. Planet gear is arranged between and engaged with the sun gear and the ring gear wherein a planet carrier that is vertically enclosing the ring gear and the sun gear is provided with a canal in which an oil pump is provided. A control valve is capable of controlling the flow of lubricant within the canal.
Claims25
A continuously variable transmission comprising:
- a sun gear connected to an input shaft;
- a ring gear fixedly connected to an output shaft;
- at least one mating pair of planet gears arranged between and engaged with said sun gear and said ring gear;
- a planet carrier adjacent to and vertically enclosing said ring gear and said sun gear through which said input shaft passes, is provided with a substantially circular closed canal;
- at least one control valve capable of controlling flow of lubricant within said canal;
- and
- at least one oil pump provided in said canal, said at least one oil pump driven by and engaged with one gear of the planet gear mating pair and capable of rotating together with the planet gear so as to allow flow of the lubricant within said canal.
