The invention discloses a subway and a bogie of the subway. The bogie comprises a frame of an H type structure, two wheel set axle boxes, driving devices, foundation braking devices, a brake pad, a primary suspension system, an auxiliary suspension system, a traction device, a rim lubricating device and a tread friction adjusting device. Each wheel set axle box comprises a wheel, an axle and an axle box body, and the axle box bodies are arranged on the frame. Each driving device comprises a traction motor and a gearbox, wherein the traction motor is rigidly suspended on the frame, and the gearbox is connected with the traction motor through a gear coupling in a transmission mode. Half of each gearbox is suspended on the corresponding axle, and the other half of each gearbox is suspended on the frame through a gearbox suspender. The wheel set axle boxes are connected with the frame through the primary suspension system, and the primary suspension system comprises four sets of multiply rubber springs. According to the arrangement, the bogie meets the requirement for the speed grade of 80 km/h, the maximum axle weight can reach 17 t, and the bogie can ensure that rim abrasion is small, and noise generated in wheel rail operation is low.
