Description

Clutch control mechanism and vehicle

Technical Field

The utility model belongs to the technical field of clutch operating mechanism, especially, relate to a clutch control mechanism and vehicle.

Background

An operating device for a friction-disc clutch is known, comprising: a lever actuator; an actuating device for pivoting the lever actuator about a pivot axis in order to apply a force to the friction disk clutch by means of the lever actuator; and a reset device for applying a reset torque to the lever actuator about the tumble axis. Furthermore, a damping device is provided for applying a predetermined damping torque to the lever actuator about the tilting axis. The actuating device has a roller which is arranged between the lever actuator and a rest element and can be moved along the lever actuator in order to change the distance between the rest element and the lever actuator.

In this form of clutch operating device, by operating the actuator, the roller is driven to the right, whereby the distance between the lever actuator and the rest element increases against the resistance of the return device and the right end of the lever actuator is moved slowly upwards. Conversely, if the actuator is no longer controlled, the reset device rapidly drives the roller back to the left and the right end of the lever actuator ceases to operate the clutch. The right end of the lever actuator can be quickly stopped to operate the clutch when the actuator is not controlled. Therefore, the clutch operating device is suitable for a normally open clutch. For normally closed clutches, the clutch is required to be quickly separated when in operation and slowly combined when in stop operation, and obviously, the clutch control device is not suitable for normally closed clutches. In addition, the rotating shaft of the lever actuator is arranged on the same side as the lever actuator, and the right end part of the actuating clutch is arranged on the other side of the lever actuator, so that the driving lever arm is short, the required driving force is large, and the requirement on the motor is high.
