摘要： A riding lawn care vehicle (10) may include a frame (60), a steering assembly (30), a brake assembly (110), and a mechanical brake linkage assembly (120). At least a first drive wheel (32) and a second drive wheel (32) of the riding lawn care vehicle (10) may be attachable to the frame (60). The steering assembly (30) may include a first steering lever (34) and a second steering lever (34), where the first and second steering levers (34) are operably coupled to the first and second drive wheels (32) respectively to facilitate turning of the riding lawn care vehicle (10) based on drive speed control of the first and second drive wheels (32) responsive to positioning of the first and second steering levers (34) along a first direction when the first and second steering levers are in an operating position. The brake assembly may be operably coupled to the first and second drive wheels (32) to enable brakes to be selectively applied to the first and second drive wheels (32). The mechanical brake linkage assembly (120) may be configured to activate the brake assembly (110) relative to the first and second drive wheels (32) in response to movement of the first and second steering levers (34) in a direction parallel to the first direction after the first and second steering levers (34) have been moved from the operating position to a non-operating position.

摘要： A hydraulic transaxle facilitates mounting a parking brake unit which requires no link mechanism and is compact. The parking brake unit includes a brake rotor provided on a rotation shaft and a locking member being displaceable between a first position where the brake rotor is locked and a second position where the brake rotor is unlocked. The locking member includes a locking portion which is engaged in a recess formed in the brake rotor that locks the brake rotor in the first position, and a non-locking portion which is placed at a position corresponding to the recess and which separates from the brake rotor in the second position. The hydraulic transaxle further includes an oil-supply mechanism capable of displacing the locking member to the second position.

摘要： A clutch assembly for a motor vehicle drivetrain for coupling coupling elements for conjoint rotation includes a clutch unit, a brake unit and at least one permanent magnet between the clutch unit and the brake unit. The clutch unit is shiftable into a coupling state in which the coupling elements are coupled to one another by shifting the clutch unit from a first position in which the coupling elements are decoupled into a second position in which the coupling elements are coupled. First and second electrically energizable coils are electrically energizable to move the permanent magnet from the first position into the second position or vice versa. A holding plate is located adjacent to the at least one permanent magnet to suppress magnetic flux from the at least one permanent magnet to the brake unit. A motor vehicle drivetrain containing at least one clutch assembly is also provided.

摘要： Notifying a driver of a number of hydraulic pressure support events. In one example, a system includes a parking brake assembly; a human-machine interface; and a parking brake electronic processor configured to generate a command to apply one or more braking components of the parking brake assembly to at least one wheel of the vehicle and generate a request for additional hydraulic pressure support. The system also includes a host electronic processor configured to receive the request for additional hydraulic pressure support; generate a command to build extra hydraulic pressure; and provide the command to the pump motor. The host electronic processor is also configured to increment a counter indicating a number of hydraulic pressure support events performed; compare the counter to a threshold value; and provide an alert to the driver via the human-machine interface when the counter exceeds the threshold value.
