Large torque compact hydraulic damping clutch, clutch control system and method

ActiveCN121382807BSpringsRotary clutchesOil canClutch control
This invention discloses a high-torque compact hydraulic damping clutch, a clutch control system, and a method. The clutch includes: a damping housing, a first side of which is connected to a transmission drive, and a damping chamber formed within the housing; a power transmission shaft rotatably mounted on the housing and connected to an engine drive, with a main damping gear fixed at one end extending into the damping chamber; and multiple sets of parallel damping gears surrounding and meshing with the main damping gear, rotatably mounted on the housing. This invention uses hydraulic damping to generate damping force, achieving switching between clutch and clutch states. This avoids relative friction that could lead to surface wear. Simultaneously, the high-pressure damping oil can also serve as a cooling medium, facilitating uniform and efficient heat dissipation during vehicle operation, and resulting in longer maintenance intervals and lower costs.

Testing device and method for testing a drive train or components within a marine propulsion system having at least one driven shaft

A testing device for testing a drive train or components within a marine propulsion system is provided and includes a first disk with a plurality of first disk depressions that faces a second disk with a plurality of second disk depressions. The first disk and the second disk are secured relative to each other so that they define a space, and a seal at outer edges of the disks is in fluid communication with the space. One of the first disk and the second disk is secured to a driven shaft. Upon rotation of the driven shaft, a load is produced due to shearing of fluid between the disks, yet no thrust is produced.
