Abstract

Transmissionssystemet för ett fordon innefattar en primäraxel (10), ett första planethjulssystem (22a) och ett andra planethjulssystem. Planethjulssystemen inkluderar ett ringhjul (12), en bärare (14) för att bära upp planethjulen (26), en första drivaxel som sitter fast i det första planethjulssystemets bärare, en andra drivaxel som sitter fast i det andra planethjulssystemets bärare, samt sekundära transmissionsorgan för att ändra rotationshastigheten för det första och det andra planethjulssystemets ringhjul. De sekundära transmissionsorganen inkluderar första styrorgan för att ändra rotationshastigheten för det första planethjulssystemets ringhjul och andra styrorgan för att ändra rotationshastigheten för det andra planethjulssystemets ringhjul, vilka första och andra styrorgan är oberoende av varandra. Ringhjulen har företrädesvis yttre kuggar (34), och nämnda första och andra styrorgan inkluderar en självhämmande snäckskruv (20) ställd mot de yttre kuggarna och en styrmotor (18) för att få snäckskruven att rotera. Vid förfarandet ändras rotationshastigheten för fordonets drivaxlar genom att reglera rotationshastigheten för ringhjulen med hjälp av de sekundära transmissionsorganen oberoende av varandra.The transmission system of a vehicle comprises a primary shaft (10), a first planetary system (22a) and a second planetary system. The planetary wheel systems include a ring wheel (12), a carrier (14) for supporting the planetary wheels (26), a first drive shaft which is secured to the carrier of the first planetary system, a second drive shaft which is fixed to the carrier of the second planetary system, and secondary transmission means for changing the speed of rotation of the first and second planetary gear ring wheels. The secondary transmission means include first steering means for changing the rotational speed of the first planetary system ring wheel and second steering means for changing the rotational speed of the second planetary system ring wheel, which first and second steering means are independent of each other. The ring wheels preferably have outer teeth (34), and said first and second steering means include a self-inhibiting wrench (20) positioned against the outer teeth and a steering motor (18) to cause the worm screw to rotate. In the process, the rotational speed of the vehicle's axles is changed by regulating the rotational speed of the ring wheels by means of the secondary transmission means independently of one another.
