The invention discloses a stepless speed regulation dual-motor hub driving system which is characterized in that a second motor is connected with a first sun gear of a first planet row, and a first gear ring of the first planet row is connected with a first fixing piece; the first motor is connected with a second sun gear of the second planet row, a second gear ring of the second planet row is connected with a first planet carrier of the first planet row, and a second planet carrier of the second planet row is a power output part connected with a hub; the one-way clutch is combined with or separated from a second gear ring of the second planet row; when the first motor is driven, a second gear ring of the second planet row is prevented from rotating reversely, so that speed reduction and torque increase of the first motor through a planet carrier of the second planet row are realized; and when the first motor and the second motor are driven, a second gear ring in the second planet row is allowed to rotate in the forward direction, so that the first motor and the second motor are coupled and subjected to stepless speed regulation through the first planet row and the second planet row. Stepless speed regulation is achieved through speed coupling of the two motors.
本发明公开了一种无级调速的双电机轮毂驱动系统,第二电机与第一行星排的第一太阳轮连接,第一行星排的第一齿圈与第一固定件连接;第一电机与第二行星排的第二太阳轮连接,第二行星排的第二齿圈与第一行星排的第一行星架连接,第二行星排的第二行星架为连接轮毂的动力输出部;单向离合器与第二行星排的第二齿圈结合或分离;当第一电机驱动时,用于防止第二行星排的第二齿圈反转,以实现第一电机通过第二行星排的行星架进行降速增扭;当第一电机和第二电机驱动时,允许第二行星排中的第二齿圈正向转动,以实现第一电机和第二电机通过第一行星排、第二行星排进行耦合及无级调速。本发明通过两个电机的速度耦合以实现无级调速。
