In a damping system for a hydraulic coupling device includes an output hub having a central axis and an annulus which surrounds the central axis, first tracks are arranged in the annulus, and a plurality of turbine mass assemblies are uniformly distributed around the central axis. Each turbine mass assembly comprises a turbine section carrying a plurality of blades and being provided with a second track corresponding to a respective first track. A roller can roll along a roller track defined by a first track and a corresponding second track so that the turbine mass assembly can move relative to the output hub and exert torque on the output hub. Each turbine mass assembly further comprises a mass plate fixedly connected to the turbine section, the output hub being arranged between the mass plate and the turbine section.

A centrifugal pendulum includes a first support plate, being able to rotate around a rotation axis; a second support plate, facing the first support plate in the axial direction and fixed to the first support plate. A mass is disposed between the first support plate and the second support plate in the axial direction. The first support plate has a first protrusion extending axially, and the first protrusion is integrally formed with the first support plate and defines a first track. The mass has a through hole extending axially, and the through hole defines a second track. The first protrusion extends into said through hole such that the first track faces the second track in the radial direction. A roller is disposed between the first track and the second track in the radial direction, and is capable of rolling against the first track and the second track, such that the mass is able to move relative to the first and second support plates and apply a torque onto the first and second support plates. The present invention also discloses a torque transmitting device comprising the centrifugal pendulum and a vehicle.

Centrifugal pendulum, torque transmitting device including the centrifugal pendulum and vehicle

A grass trimmer includes a trimming head, a driving device for driving the trimming head to rotate so as to cut vegetation and an operating device for a user to operate so as to control the driving device. The trimming head includes a spool and a line holding member, the spool is used to wind a cutting line, and the line holding member is formed with a line holding structure. The driving device includes a motor. The grass trimmer has an auto-winding mode. In the auto-winding mode, the motor drives at least one of the spool and the line holding member to make the spool and the line holding member rotate relatively so that the cutting line is wound on the spool automatically.
