Abstract: 一种限滑差速器的控制方法、装置及设备。方法包括：获取车辆的状态信息以及车辆的实际扭矩；根据所获取的状态信息判断车轮是否打滑；若判定车轮打滑，则控制限滑差速器的扭矩等于车辆的实际扭矩。这样能够减小甚至消除左右轮速差，将驱动扭矩全部用于车轮的有效驱动，避免车轮打滑，因此能够帮助车辆及时脱困。

Abstract: Aspects of the disclosure provide an electric actuator including a first driving source coupled to an output through a first pathway created by a transmission, a second driving source coupled to the output though a second pathway created by the transmission that, upon the electric actuator losses electrical power to the electric actuator, causes the output to be positioned at a fail-safe position, a differential coupled to the first driving source and the second driving source through a third pathway created by the transmission to store energy from the first driving source in the second driving source, and an eddy current brake coupled to the output through the transmission that reduces a speed at which the second driving source moves the output to the fail-safe position.

Abstract: An electric drive module that includes an electric motor, a differential assembly, and a transmission that transmits rotary power between the electric motor and the differential assembly. The transmission has first and second reductions. The first reduction has a drive gear, which is rotatable about a first axis, and a pair of first reduction gears that are each meshingly engaged to the drive gear rotatable about a respective second axis. The second axes are spaced apart from one another and are parallel to the first axis. The second reduction has a driven gear and a pair of second reduction gears. The driven gear is rotatable about a third axis that is parallel to the first axis. Each of the second reduction gears is being meshingly engaged to the driven gear and non-rotatably coupled to an associated one of the first reduction gears.

Abstract: A vehicle has an engine, an accelerator control, a limited slip differential (LSD) mounted on an axle driven by the engine, and left and right wheels operably connected to the LSD. An accelerator control position is sensed. A speed of the vehicle is optionally sensed. In order to prevent wheel spin, a high load is selectively applied to the LSD when the accelerator control position meets or exceeds a predetermined position threshold. Optionally, application of the high load may depend on the speed of the vehicle being less than a predetermined speed threshold, the accelerator control position concurrently meeting or exceeding the predetermined position threshold. In order to enhance directional stability of the vehicle, a stabilization load is optionally applied when the speed of the vehicle meets or exceeds the predetermined speed threshold.

Abstract: A hydraulic control unit that delivers hydraulic fluid to a limited slip differential includes a hydraulic control unit housing, a motor and a pump. The hydraulic control unit housing has a manifold housing portion and an accumulator housing portion. The manifold housing portion defines a fluid pathway arrangement for communicating fluid along at least a first fluid pathway. The accumulator housing portion houses an accumulator assembly having a biasing assembly and a piston. The accumulator housing portion and manifold housing portion cooperate to form an accumulator chamber that houses the biasing assembly. The motor is disposed on the first side of the manifold housing portion. The pump is disposed on a second side of the manifold portion, opposite the first side. The pump is configured to pump fluid into the accumulator chamber of the accumulator housing portion.

Abstract: The present disclosure relates to a limited-slip clutch system and method. In one aspect, the limited-slip clutch actuation system can include a hydraulic pump operated by a variable speed drive wherein the pump can be configured to generate hydraulic flow in a hydraulic circuit including an actuation branch line that actuates a clutch. The circuit may also include a flow regulating valve for regulating a hydraulic fluid flow rate through the hydraulic circuit wherein the flow regulating valve can be configured to prevent the hydraulic fluid flow rate from exceeding a set maximum flow rate regardless of a magnitude of the hydraulic pressure in the hydraulic circuit. In operation, the pump speed can be controlled based on a command pressure set point and the measured pressure in the actuation branch line and to minimize operational costs by operating the pump at a transition region of the system pressure-pump speed curve.
