  • Patent number: 10690194
    Abstract: Clutch kits and methods for converting a stock clutch assembly and the clutch assemblies resulting therefrom. Such a method entails modifying a stock clutch assembly comprising a stock drum and stock friction and driving plates installed in an interior cavity of the drum. The method includes securing a pressure plate to the drum with threads to enclose stock or modified friction and driving plates within the interior cavity of the drum. The pressure plate can be configured to axially externally extend the interior cavity of the drum so that additional friction and/or driving plates may accommodated within the interior cavity.

  • Patent number: 10683009
    Abstract: A method for operating a drive train of a motor vehicle in an inclined position, in particular an agricultural or municipal utility vehicle. A connection between a prime mover and at least one drive axle of the motor vehicle is automatically disconnected as part of a function upon actuation of a service brake for stopping the motor vehicle monitored by at least one sensor. To avoid uncontrolled backward rolling, provision is made that a maximum brake pressure applied to achieve or maintain the standstill of the motor vehicle is determined and monitored by continually measuring a brake pressure applied by the service brake. Upon the brake pressure falling below the maximum brake pressure minus a pre-definable pressure difference, the function is automatically deactivated and thus the connection is automatically re-established between the prime mover and the at least one drive axle.

    Abstract: A device for actuating a clutch, having an actuator with a pneumatic chamber (KP) delimited by a pneumatic active area (AP), two hydraulic chambers (KH1, KH2) each delimited by a hydraulic active area (AH1, AH2), and a control element (G) that is actively connected to the clutch and can be moved and subjected to a force by the active areas. The pneumatic active area is subjected to a pneumatic pressure by a compressed air source (QP) to generate force in an actuating direction (B). The hydraulic chambers can each be hydraulically connected to a storage container (QH) for hydraulic fluid by an electromagnetically actuatable 2/2-way proportional valve (VH1, VH2). Furthermore, a control system (CPU) is provided to independently control the pressure application of the pneumatic chamber and valve positions of the 2/2-way proportional valves.

  • Patent number: 10677349
    Abstract: Pressure regulation valve control device has line pressure regulation valve (4) having line pressure solenoid (41) and line pressure spool valve (42) and CVT control unit (8) controlling secondary pressure (Psec) by actuating the line pressure spool valve (42) by solenoid pressure (Psol) produced by controlling current command value (I) to the line pressure solenoid (41). CVT control unit (8) has abnormality control unit (81). The abnormality control unit (81) is configured to, when decrease in secondary pressure (Psec) is detected during travel, execute, during travel, abnormality control that increases solenoid pressure (Psol), supplied to line pressure spool valve (42) from line pressure solenoid (41), more than solenoid pressure (Psol) of a time when the decrease in secondary pressure (Psec) is detected. With this, even when the decrease in the pressure is detected during travel, the decrease in the pressure is suppressed during travel while reducing influence on vehicle travel.

  • Patent number: 10676094
    Abstract: Methods, devices and systems are provided for determining a connection state of an all wheel drive (AWD) assembly in a vehicle. The method includes receiving, by a vehicle, a message indicative of a hazard and a hazard location on the road and determining a distance to the hazard location from the vehicle. In response to the distance to the hazard location being below a first threshold distance, a state for an AWD assembly in the vehicle is set to a connect state. In response to the distance to the hazard location being above the first threshold, the time for the vehicle to reach the hazard location is determined. If the time to the hazard location is below a threshold AWD connection time, the state for the AWD assembly is set to the connect state.

  • Patent number: 10655732
    Abstract: A gear position detecting device includes a rotation angle sensor for detecting a turn position of a shift drum and a position sensor for detecting that the shift drum is at a neutral position. The rotation angle sensor is a volume sensor that linearly increases or decreases an output voltage according to a turning motion of the shift drum. The neutral position is set in such a way as not to overlap a dead zone. It is determined according to an output signal of the rotation angle sensor and an output signal of the position sensor whether the shift drum is at a reverse gear position located between the neutral position and the dead zone or a fifth gear position turned by 360 degrees from the reverse gear position. Such detecting device detects a gear position with a high accuracy even if the number of gear positions are increased.
