    Abstract: The invention relates to a device (10) for actuating a clutch, comprising an actuator (12) having a pneumatic chamber (K
    p ) delimited by a pneumatic active area (A
    p ), two hydraulic chambers (K
    H1 , K
    H2 ) each delimited by a hydraulic active area (A
    H1 , A
    H2 ), and a control element (G) that is actively connected to the clutch and can be moved and subjected to a force by said active areas. In order to generate force in an actuating direction (B) against a restoring force acting in a restoring direction (R), the pneumatic active area is subjected to a pneumatic pressure by a compressed air source (Q
    P ). The hydraulic chambers can each be hydraulically connected to a storage container (Q
    H ) for hydraulic fluid by means of an electromagnetically actuatable 2/2-way proportional valve (V
    H1 , V
    H2 ). Furthermore, a control system (CPU) is provided, by means of which the pressure application of the pneumatic chamber and valve positions of the 2/2-way proportional valves can be controlled independently of each other. In this way, by closing either one or the other, or both, of the 2/2-way proportional valves, by means of the respectively associated hydraulic active areas, an actuator movement in the actuating direction or in the restoring direction can be braked in a controlled manner, which allows a sensitive clutch actuation in an energy-efficient manner.

    Abstract: A clutch apparatus 29 switches the transmission and the cutoff of the rotating force between a steering-wheel-side housing 76 and a tire-side housing 78. The clutch apparatus 29 is configured such that a first mode, a second mode and a third can be switched among these three modes. In the first mode, the rotating force is not transmitted between the steering-wheel-side housing 76 and the tire-side housing 78. In the second mode, the steering-wheel-side housing 76 and the tire-side housing 78 are being mutually locked in place and, in this locked state, the rotating force can be transmitted to for the rotation in the both directions. In the third mode, the transmission of the rotating force can be canceled such that while the rotating force can be transmitted, between the steering-wheel-side housing 76 and the tire-side housing 78, relative to the rotation in one direction, the rotation of either the steering-wheel-side housing 76 or the tire-side housing 78 in the other direction is allowed.

    Abstract: A method of calibrating the control current start-up threshold in a proportionally controlled drive system (11) for a work vehicle (10) is disclosed. To determine a current threshold value for use in the system (11) a control current (IC1/IC2) exhibiting a relatively low value is first applied to the system. Subsequently, the steps of repetitively increasing the control current to a control current start value at which system motion starts and decreasing the control current to a control current stop value at which system motion substantially stops are repetitively conducted. The resultant control current start values and control current stop values are stored in a memory (117). The stored control current start values and control current stop values are then averaged to determine a control current threshold value for use in controlling the system.

    Abstract: The present invention provides a clutch connection method which controls the disconnection/connection of a wet friction clutch on the basis of a duty pulse outputted from an electronic control unit. When the clutch is connected, the electronic control unit initially outputs a start duty (Dst) for largely connecting the clutch as far as the vicinity of a torque point, and, thereafter, outputs, at prescribed time intervals (Δt), a gradual connection duty (Dk) for gradually connecting the clutch, and determines a gradual connection duty value on the basis of a clutch input/output side revolution difference ΔN. Since the clutch is gradually connected while monitoring the clutch connection state, variations between connection times and connection shock, resulting from individual clutch differences or the like, can be eliminated, whereby it is possible to achieve a stable feel. Further, in control which connects the clutch in sync with completion of a transmission gear shift, a plurality of clutch connection modes (an engine plus mode, an in-shaft plus mode, and a synchro mode) are preset, and the clutch connection modes are selected in accordance with the size of clutch input-side and output-side revolution numbers upon completion of a gear shift. Clutch connection is performed which conforms to actual conditions since a clutch connection mode is selected in accordance with the size of clutch input/output side revolution numbers rather than with respect to a shift-up or a shift-down.

    Abstract: The present invention aims to enable the accurate learning of a true torque point in a wet friction clutch (3), prevent the clutch connection shock by absorbing the response delay upon an ordinary clutch connection control, and to successfully combine the time lag and shock. In the present invention, the value (D) itself of the duty ratio of the duty pulse output from the ECU (16) is learned as the torque point (Dm). In a power transmission device of a vehicle having a fluid coupling (2) and the wet friction clutch (3)provided in series between the engine (E) and transmission (T/M), the value (Dm) of the duty ratio at the time when the clutch input side revolution (Nt) decreases to a value lower than the engine revolution (Ne) by a prescribed revolution (Nm) during the process of gradually connecting the clutch 3 is learned as the torque point. Preferably, learning is conducted after the elapse of a prescribed waiting time (Δt1). During an ordinary clutch connection control, a prescribed start duty (Dst0) for connecting the clutch (3) broadly up to a point close to the torque point (Dtb) is initially output from the ECU (16), and a gradual duty (Dk) is output after retaining such start duty (Dst0) for a prescribed time (Δt3). Preferably, a first gradual duty (Dk1) for gradually connecting the clutch quickly is output, and a second gradual duty (Dk2) for gradually connecting the clutch slowly is output thereafter.
