Abstract: The disclosure discloses a transmission system capable of implementing four-wheel drive and an operating model thereof. The transmission system includes an odd shift motor, an even shift motor, a front-wheel drive shaft, a rear-wheel drive shaft, a front-wheel output shaft gear disposed on the front-wheel drive shaft, and a rear-wheel output shaft gear disposed on the rear-wheel drive shaft. The front-wheel output shaft gear and the rear-wheel output shaft gear are connected by a front/rear drive shaft coupling sleeve. In the disclosure, coordinated control of two motors allows the motors to operate with high efficiency to the maximum, which improves the efficiency of the transmission system. A four-wheel drive model and a two-wheel drive model are implemented through the coordinated control of two motors. Moreover, in the disclosure, sensor information is used to synchronously control a rotational speed during gear shift, which can reduce the impact during the gear shift.

Abstract: A self-adaptive heavy-duty gear transmission walking device includes a guide track. A carrying seat is slidably installed on the guide track. A loading platform is arranged on the carrying seat, and matching frames are arranged at the bottom of the carrying seat and positioned opposite from each other. A first driving mechanism, a walking mechanism, a first support bracket, a stop mechanism, and a second support bracket are arranged on the carrying seat. A vertical support mechanism and a horizontal support mechanism are arranged in the matching frame. The first driving mechanism is connected to one end of the walking mechanism. The walking mechanism penetrates through the carrying seat and is magnetically connected to the guide track. The other end of the walking mechanism is connected to a first transmission shaft. The first transmission shaft penetrates through the first support bracket and is fixedly installed with a brake disc.

Abstract: A nickel-hydrogen battery pack heat removal system for hybrid vehicle is provided. The system includes a battery box, a power battery pack (8), a battery support frame (9), a support bar (5), an air inlet (1), an air outlet (6) and a fan (7). Batteries in the power battery pack (8) are aligned in parallel in two layers one above the other in the battery support frame (9) of the battery box, and the support bar (5) and the battery support frame (9) are fixed on the upper and lower soleplates respectively of the battery box. The air inlet (1) is set at one end of the battery box, the air outlet (6) is set at the other end of the battery box, and the fan (7) is fitted at the air outlet (6). The system further includes conduction plates (2) in the shape of circular arcs, said conduction plates (2) being fitted on the opposing faces of the two upper and lower batteries which are closest to the air inlet (1).
