MOTOWHEEL Russian patent published in 2012 - IPC B60K7/00 F16H1/32 

FIELD: transport.

SUBSTANCE: invention relates to vehicles and may be used in open space at extreme temperatures. Motowheel comprises case, motor and planetary reduction gear. Every planet pinion is made up of three wheels (8a, 8b, 9) fitted on common axle and coupled by elastically pre-strained elastically-compliant shafts 10. Outer surface of motor rotor 3 accommodates bushing 4 with ring element 5 that has cylindrical outer friction working surface interacting with outer friction working surface of central wheel 9 of each planet pinion. Motor stator 2 is arranged inside rotor 3. Motowheel case consists of two parts 6, 7, one part 6 is rigidly coupled with stator 2 while another one 7 may rotate. Inner surfaces of case parts are furnished with ring elements (11a, 11b) with inner friction working surfaces interacting with mating outer working surfaces of planet pinions (8a, 8b).

EFFECT: increased specific power output, possibility of operation in open space at temperatures approximating to 450 K.
