Hybrid transmission device

A hybrid transmission device, comprising:

• a central housing;
• an input member for receiving power from an internal combustion engine;
• an output member for delivering power from the transmission;
• a first and second motor/generators;
• an energy storage device for interchanging electrical power with said first and second motor/generators;
• a control unit for regulating the electrical power interchange between the energy storage device and the first and second motor/generators and also for regulating electrical power interchange between the first and second motor/generators;
• the first motor/generator comprises a first stator supported interiorly of the central housing and a first rotor fixed secured to a first motor/generator shaft;
• the second motor/generator having a second stator supported interiorly of the central housing, a second rotor fixed secured to a second motor/generator shaft;
• a first planetary gear set;
• a second planetary gear set operably connected to the first planetary gear set;
• a third planetary gear set;
• a fourth planetary gear set operably connected to the third planetary gear set;
• a fifth planetary gear set;
• a sixth planetary gear set operably connected to the fifth planetary gear set;
• the first planetary gear set, the second planetary gear set, the third planetary gear set, the fourth planetary gear set, the fifth planetary gear set and the sixth planetary gar set are coaxially aligned with each other;
• the six coaxially aligned planetary gear sets, each planetary gear set utilizing sun gear, ring gear, a carrier and a plurality of planet gears;
• the sun gear and ring gear in each planetary gear set meshingly engage a plurality of planet gears;
• the input member is rotatably connected to a first carrier in the first planetary gear set for delivering power from said internal combustion engine;
• the output member is rotatably connected to a sixth carrier in the sixth planetary gear set for delivering power from said hybrid transmission device;
• the first and second motor/generators are coaxially aligned with each other and with the six planetary gear sets;
• a first sun gear in the first planetary gear set connected to the first motor/generator rotor through the first motor/generator shaft;
• a second sun gear in the second planetary gear set connected to the second motor/generator rotor through the second motor/generator shaft;
• eight caliper brake systems;
• four of the caliper brake systems are used to the first and second planetary gear sets;
• another four of the caliper brake systems are used to the third, fourth, fifth and sixth planetary gear sets;
• each caliper brake system comprises a dry disc, a speed sensor for watching state of the dry disc, a pair of pad plates, two pairs of independent hydraulic pistons and a pair of calipers;
• a plurality of speed teeth processed on the circumferential surface of the dry disc;
• the caliper brake systems are mounted on outside of the hybrid transmission device housing;
• a hydraulic control unit communicates with the caliper brake systems by hydraulic circuits;
• five pairs of shift gear systems;
• each shift gear system comprises a shift gear, a shift shaft, a pair of spacing rings and a pair of bearings;
• the shift gear is secured to the shift shaft;
• and
• the dry disc is secured to the shift shaft.
