Abstract: The present disclosure discloses a split-type electromagnet, wherein the split-type electromagnet comprises a housing and an iron core, the housing and the iron core are of a split type, wherein the iron core is fixed within the housing after the coil has been wound on the iron core, and the housing is a cylindrical body or an ellipsoidal body or a cross section of the housing is a sector-shaped ring or a rectangular ring. Compared with the integrated type of the housing and the iron core in the prior art, the winding of the coil of the electromagnet is more convenient. Furthermore, when the cross section of the housing of the electromagnet is a sector-shaped ring, a plurality of electromagnets are combined to form an electromagnet unit, and when the space is restricted, the electromagnet unit may be used to complete the electromagnetic attraction.

Abstract: This Application pertains to an electromagnetic dog clutch, including a movable gear sleeve and a fixed toothed sleeve that are engaged to transmit power. The movable gear sleeve is provided with contrate transmission teeth or tooth spaces, and the fixed toothed sleeve is correspondingly provided with contrate tooth spaces or transmission teeth. The transmission teeth have a uniform thickness in a direction of tooth length, tooth spaces that engage with the transmission teeth have a sector-shape in a direction of tooth space length, and the width of two sides of the tooth spaces gradually increases outwardly along the radial direction of the fixed toothed sleeve and gradually decreases inwardly along the radial direction of the fixed toothed sleeve. By employing the engagement of transmission teeth of uniform thickness and sector-shaped tooth spaces, the transmission teeth can more easily engage with the tooth spaces, and more easily realize surface contact.

Abstract: The present disclosure discloses a longitudinally placed vehicle driving assembly having a single power source, which solves the technical problems of the vehicle driving assemblies in the prior art such as larger volumes and poor transmission performances. The driving assembly is connected to a transmission shaft or a vehicle axle half shaft of a vehicle and provided with an automatic transmission. The automatic transmission includes an input shaft (2). A power source (1) is connected to the input shaft (2). An output shaft (10) is provided coaxial with the input shaft (2). An intermediate shaft (9) is provided parallel to the input shaft (2). A first-stage reduction-gear train is installed through the input shaft (2) and the intermediate shaft (9). An Nth-stage reduction-gear train is installed through the intermediate shaft (9) and the output shaft (10), wherein N≥2. Each of the stages of the reduction-gear trains includes a pair of gears having a different transmission ratio. The output shaft (10) of the power source (1) and the input shaft (2) of the automatic transmission are integrally manufactured. A rear cover of the power source (1) and a front housing of the automatic transmission are integrated. The driving assembly is placed in the front of the vehicle, and drives rear wheels of the vehicle.

Abstract: An automatic transmission comprises a double-contrate-tooth combined fluted disc (120) and a two stage transmission ordinary gear train. The gear shifting mechanism of the transmission is the double-contrate-tooth combined fluted disc (120), which has double contrate teeth, namely, left contrate teeth and right contrate teeth. By the axial moving of the double-contrate-tooth combined fluted disc (120) on the transmission output shaft, its left contrate teeth and right contrate teeth respectively engage with the contrate teeth of the first gear and the second gear reduction gears, to realize the second shift position and the first shift position, and when it engages with neither of them, the transmission is in the neutral shift position. The left contrate teeth and the right contrate teeth are individually independent or integrally assembled structures. Compared with the traditional AMT, the transmission does not need a synchronizer; therefore, the structure is simple, the reliability is increased, the gear shift duration is shortened, the shifting shock is relatively small, the manufacturing cost is low, and it is easy to realize industrialization. The transmission has simple arrangement of gears, short axial dimension, small weight, and occupies small room, and meets the development trend of light weighting and fuel saving.

Abstract: A vehicle electrically driving assembly, connected to the rear or front axle half shaft of the vehicle, that includes: an electric motor, a speed reducer, an electromagnetic tooth-mounted clutch and a differential. The speed reducer has multiple stages of gears, an input shaft and an intermediate shaft; the differential is connected between the axle half shafts; the electromagnetic tooth-mounted clutch is installed on the input shaft or the intermediate shaft of the speed reducer or on the axle half shafts. When the electromagnetic tooth-mounted clutch is in engagement, driving force of the electric motor is transmitted to the vehicle axle via the speed reducer and the electromagnetic jaw clutch, to provide an auxiliary driving force to the vehicle. When the power of the entire vehicle is insufficient at the acceleration phase, the electrically driving assembly, by using the electromagnetic jaw clutch, provides an auxiliary driving force to the entire vehicle.
