Claims
- 1. A speed change system and speed controlling system, comprising:
- an input shaft 512 for receiving rotational input with a first section 512A and a terminal section 512B and an input sun gear 514 integrally formed between said first section 512A and said terminal section 512B of said input shaft to enable simultaneous rotation with said input shaft;
- a speed change control shaft 516 with a first end 516A and a second end 516A' coaxially and rotatably mounted on said input shaft 512 to enable independent rotation about said input shaft and a plurality of splines 516S formed at the second end 516A' of the speed change control shaft 516;
- a carrier 518 integrally formed at said first end 516A of said speed change control shaft 516 to enable simultaneous rotation with said speed change control shaft 516;
- a carrier 520 rotatably mounted on said terminal section 512B of said input shaft to enable independent rotation about said terminal section 512B;
- a plurality of locking pins 522 with each said locking pin 522P secured to and interlinking said carriers 518, 520 to enable simultaneous rotation of said carriers about said speed change control shaft and said input shaft, respectively;
- a plurality of planetary gears 524 with each said planetary gear 524G being rotatably mounted on each said locking pin 522P and being meshed with said input sun gear 514;
- an output ring gear 530 coaxially and rotatably mounted on said terminal section 512B of said input shaft, and being meshed with each said planetary gear 524G and terminating in an output shaft 528;
- a fixed shaft 562 coaxially and rotatably mounted on said speed change control shaft 516 to enable said speed change control shaft 516 to rotate independently of said fixed shaft and further including a fluid passageway 565 formed therein with said fluid passageway in fluid communication with a fluid inlet 564;
- a cover 552 secured to said first section 512A of said input shaft to enable simultaneous rotation therewith and having a plurality of fluid outlets 554 formed therethrough;
- an impeller 556 integrally formed with said cover 552 and being rotatably mounted on said fixed shaft 562;
- a turbine 558 operatively positioned opposite said impeller 556 and secured to said second end 516A' of said speed change control shaft 516;
- a stator 560 positioned between said turbine 558 and said impeller 556 and mounted on said fixed shaft 562 to permit oneway rotation about said fixed shaft 562 and with said fluid passageway 565 terminating between said stator 560 and said impeller 556; and
- a housing 566 for operatively enclosing said turbine 558, said impeller 556 and said stator 560, mounted to said fixed shaft 562 and rotatably secured to said input shaft 512 to permit independent rotation of said input shaft 512 and having a fluid outlet 568 formed in said housing to enable, in use, fluid to circulate therethrough and with said housing operatively secured to prevent rotation.
- 2. The speed changed system and speed controlling system of claim 1 further including an overdrive system operatively connected thereto for increasing rotational output of said output shaft to define a stepless automatic variable transmission.
