摘要： A vehicle includes a drive wheel, an engine, an accelerator pedal, a torque converter, a clutch, and a controller. The drive wheel is configured to propel the vehicle. The engine is configured to generate power and to deliver power to the drive wheel to accelerate the vehicle. The accelerator pedal is configured to generate an acceleration request based on a pedal position. The torque converter is disposed between the engine and the drive wheel. The clutch is disposed between the engine and the drive wheel and is configured to bypass the torque converter. The controller is programmed to, in response to depressing the accelerator pedal to a position that corresponds with accelerating the vehicle at a desired magnitude, adjust the torque of the engine to accelerate the vehicle at the desired magnitude, regardless of the state of the clutch.

摘要： An electrified drivetrain for a vehicle includes a first electric machine, a second electric machine, a clutch, an HVAC compressor, and a controller. The second electric machine is rotatably coupled to a geartrain, the first electric machine is rotatably coupled to the HVAC compressor, and is rotatably couplable to the geartrain via the clutch, and the clutch is operative in a first state and a second state. The first electric machine is rotatably coupled to the geartrain when the clutch is controlled to the first state, and is decoupled from the geartrain when the clutch is controlled to the second state. The controller is operatively connected to the first and second electric machines, the clutch, and the HVAC compressor to control operation of the electrified drivetrain. The first electric machine can be used as a heater element and to provide mechanical power to the drivetrain.

摘要： The invention relates to a freewheeling device 11 in the case of which the outer freewheeling component 14 and the inner freewheeling component 17 are connected in the main torque transmitting direction by locking members 25 which engage apertures 24 of the inner freewheeling component 17 and recesses 26 of the outer freewheeling component 14 and which permit one of the freewheeling components 14 to be overtaken by the other freewheeling component 17 when a certain speed is exceeded. If the speed is below the specified speed, an additional switching element is released via a speed-dependent switching device 29, so that the switching element 30, under the influence of a spring 36, is transferred into a position where it supports the locking member 25 to prevent them from escaping radially inwardly, thereby cancelling the freewheeling function. Thus, at low speeds, torques may be transmitted in both directions of rotation via the freewheeling device 11, whereas the freewheeling function is ensured at higher speeds.

摘要： A control device of a remote free wheel hub mechanism includes a free wheel hub mechanism, an actuator and a control circuit. The control circuit further includes a two-wheel-drive circuit, a four-wheel-drive circuit, a transfer shift position detecting sensor, and an engine rotation drive detecting sensor. One of the two-wheel-drive circuit and the four-wheel-drive circuit in the transfer shift position detecting sensor moves to a closed condition independently of the shift position when the engine is stopped, and the transfer shift position detecting sensor correspondingly produces a signal of one of the two-wheel-drive and four-wheel-drive conditions, respectively. The engine rotation drive detecting sensor detects a rotational condition of an engine and produces a signal which closes one of the two-wheel-drive and the four-wheel-drive circuits when the engine is stopped.

摘要： A differential assembly has a rotatable, open sides casing into which the opposite, splined ends of axial shafts extend. Each axial shaft has a splined collar ring mounted upon it and a surrounding coupling ring. A drive rod, secured to the casing, extends between the opposed coupling rings and has wedge shaped surfaces fitted within aligned V-shaped notches formed on facing surfaces of the coupling rings. Disk plate type clutches releasably connect each of the coupling rings to their adjacent collar rings. The clutches include Belleville spring washer plates which resiliently force the coupling rings inwardly against the drive rod for maintaining the rod wedge shaped surfaces in face to face contact with their adjacent notch walls. The coupling rings, clutches and collar rings are assembled into the casing through its open side and thereafter, the rod is inserted endwise into the casing, between the coupling rings, through a rod receiving hole in the casing. When the casing rotates, the drive rod wedge surfaces drive the coupling rings and also, press them outwardly for connecting the clutch for engaging the coupling rings with the collars to rotate the axles. If either axle rotates faster than the casing, the outward pressure of its rod wedge surface against its coupling ring notch is momentarily relieved and therefore, its clutch is temporarily disconnected so that axle may free wheel until it returns to the casing speed.
摘要翻译：差速器组件具有可旋转的开口侧壳体，轴向轴的相对的花键端部延伸到其中。每个轴向轴具有安装在其上的花键轴环和周围的联接环。固定到壳体上的驱动杆在相对的联接环之间延伸并且具有嵌合在形成在联接环的相对表面上的对准的V形凹口内的楔形表面。盘式离合器将每个联接环可释放地连接到其相邻的环形环。离合器包括Belleville弹簧垫圈板，其将联接环向内弹力地推压到驱动杆上，以将杆楔形表面保持在面对面以与它们相邻的切口壁面接触。联接环，离合器和套环通过其开放侧组装到壳体中，然后通过壳体中的杆接收孔将杆端部插入壳体中，在联接环之间。当壳体旋转时，驱动杆楔形表面驱动联接环，并且还向外按压它们以连接离合器，以使联接环与套环接合以使轴旋转。如果任一车轴比壳体旋转得更快，其杆楔表面对其联接环槽口的向外压力暂时释放，因此其离合器暂时断开，从而轴可以自由轮直到其返回到壳体速度。

摘要： The device for disconnecting the wheels from a vehicle's optional drive is mounted inside the support of the axle shaft, and the wheel hub is splined onto the axle shaft. The universal joint is diametrically positioned in relation to the support of the axle shaft by a bearing. The universal joint has an internal splined section which corresponds to an internal splined section on the clutch disc for "engage" and "disengage" positions. A fluid responsive actuating device is provided including a movable member in the form of a diaphragm or a piston connected to the clutch disc for axially moving, in response to the pressure or pressure differential from a fluid source to effect the engagement and disengagement of the clutch disc splines in relation to the axle shaft and universal joint splines.

摘要： A vehicle drive system particularly suited for snow blowers includes a main sprocket rotatably carrying a first and second pawl. Each pawl drivably engages a respective sprocket. The first sprocket is fixably mounted to a first axle means such that rotation of the main sprocket causes the first pawl to drivably engage the first sprocket to rotate the first axle means. A second sprocket is fixably engaged to a second axle means such that rotation of said main sprocket causes a second pawl to drivably engage the second sprocket to cause rotation of the second axle means. Friction means supplies sufficient drag to the pawl such that rotation of main sprocket causes each of the pawls to assume an engaging orientation with their respective sprockets. Each of the pawls can be selectively disengaged from a drive orientation by manually advancing the respective axle means, i.e., when an operator maneuvers the vehicle for turning.
