Can the planetary gear reducer require no gear ring? The solar wheel is active and the planet carrier outputs
The operating conditions of the 5 shift operation components in each gear are shown in table 7-2. The table shows that when the planetary gear box in any file outside the parking stall and neutral position, 5 shift operation has two components in the work of the state (joint, brake or lock), the remaining 3 do not work (separation, release or free state); in the work state the two shift operation component has at least one clutch is C1 or C2, so that the input shaft and the planetary gear box is connected, when any forward, C2 clutch is engaged, the input shaft and the planetary gear mechanism before the ring gear engagement, the ring gear to become active, therefore C2, also known as forward clutch clutch (Forward Clutch). Reverse gear, clutch C1 is engaged, separation of C2, then enter the joint shaft and the planetary gear mechanism before and after the sun wheel assembly, the front and rear sun wheel components become active, in addition, the clutch C1 in 3 files (direct file) when bonding, therefore, also known as clutch C1 high reverse clutch (High Reverse Clutch). The brake B1 only works in the 2 gear, called the 2 gear brake or the Brake (2nd or 2nd Clutch). The brake B2 works in both the gear and reverse gear, so it is called the low and reverse gear brake, or the low / reverse brake (Low Reverse Brake or Low Reverse Clutch).
Transmission diagram (4) 5 shift operation component is arranged in the Simpson planet gear mechanism (2 clutches and 2 brakes and 1 one-way overdrive clutch), to be a planetary gearbox with 3 forward and 1 reverse gear, the 5 gear shift operation module the layout as shown in Figure 7-5, C1 is used to connect the clutch input shaft and the clutch wheel assembly before and after the sun, C2 is used to connect the input shaft and the ring gear, brake for B1 solid was fixed after the planet carrier, B before and after the sun wheel brake assembly, brake speed clutch F11 B2 and Dan Xiangchao and B2 can use the band brake or disc brake.

(1) Simpson Simpson type planetary gear box, planetary gear box is composed of a Simpson type planetary gear mechanism and relative shift operation components, most automatic transmissions are using this planetary gearbox; Simpson type planetary gear mechanism is a planetary gear mechanism is very famous, it is composed of two internal meshing planetary gear mechanism combination, its structure is characterized by (1) before and after the two planetary sun gear is connected into a whole, called the sun before and after the wheel assembly (2) before a planetary planetary frame and a planetary gear ring connected to the other as a whole, called on star frame and a rear ring gear assembly (3) and the output shaft is usually the former planet carrier and the ring gear assembly (Figure 7-4). So, the agency became the 4 independent components (1) before the ring gear (2) before and after the sun wheel assembly (3) after the star frame (4) before and after the star frame ring gear assembly; according to the different number of forward stalls, the Simpson type planetary gear box is divided into 3 Simpson gear planetary gear transmission and Simpson Thompson type 4 gear planetary gear box two.
