摘要:
A driving force transmission control apparatus includes a multiple disc clutch including a plurality of outer clutch plates, and a plurality of inner clutch plates; a pressing mechanism that presses the multiple disc clutch; and a control portion that controls the pressing mechanism. The outer clutch plates and inner clutch plates are engaged with an intermediate shaft and an inner shaft respectively. The control portion makes a determination (S11) as to whether the multiple disc clutch is in a first operating condition in which the multiple disc clutch is pressed with a relative rotation speed between the intermediate and the inner shafts being equal to or higher than a predetermined value (S14), or in a second operating condition in which the multiple disc clutch is pressed with the relative rotation speed being lower than the predetermined value (S12), and the control portion controls the pressing mechanism (S16, S17) based on a result of the determination (S13, S15).
摘要:
A method to estimate an amount of force in a clutch pack of a clutch actuation system. The method includes engaging an actuation motor to apply a set point force to the clutch pack and monitoring a position of the actuation motor when the set point force is applied. Additionally, the method includes determining one or more clutch clamping curves and one or more clutch releasing curves based on a relationship between the position of the actuation motor and an amount of torque applied by the actuation motor at position of the actuation motor. The method further includes modeling one or more frictional characteristics of the clutch actuation system and estimating an amount of clamping and releasing force within the clutch pack by using a control unit. The amount of torque applied to the clutch pack between the clutch clamping and releasing curves at the set point force is maintained.

A clutch control system for vehicle is applied to a vehicle (1) having a clutch (3) and a transmission (4) disposed in a power transmission path (6) from an engine (2) to a vehicle wheel (5). The system includes a first rotational speed detecting unit (28) to detect a driving side rotational speed of the clutch (3), a second rotational speed detecting unit (16, 50) to detect a driven side rotational speed of the clutch (3), a half-clutch control unit (10, S5, S33, S34, S44, S45, S53 to S55), and a half-clutch transition control unit (10, S4, S11 to S13). The half-clutch control unit (10, S5, S33, S34, S44, S45, S53 to S55) executes a first half-clutch control on the clutch actuator (11) when a gear position of the transmission (4) and a rotational direction of a driven side portion (32) of the clutch (3) are matched and executes, on the clutch actuator (11), a second half-clutch control, differing from the first half-clutch control, when the gear position of the transmission (4) and the rotational direction of the driven side portion (32) of the clutch (3) are not matched.

A driving apparatus (100) for a vehicle includes a transmission mechanism (30) including a plurality of gear sets having different gear ratios and being positioned between an input shaft (32a, 32b) and an output shaft (37), a clutch (20) changing a transmission state of a rotation torque between the input shaft (32a, 32b) of the transmission mechanism (30) and a driving shaft (12) to which the rotation torque is supplied from a driving source (10), and a control portion (31) establishing the torque transmission state between the input shaft (32a, 32b) and the output shaft (37) by connecting the input shaft (32a, 32b) to a gear (33', 34a, 34b, 34c, 34d, 34e, 34f, 34r, 35a, 35b, 35c, 35d, 35e, 35f, 35r, 38) configuring the gear set.

An electromagnetic actuator includes a supporting member (13,33,213) supporting an electromagnetic coil (15, 35) around which a wire is wound, a moving member (14, 34, 214) positioned facing the supporting member so as to move forward and backward, and an actuating force transmitting member (16, 36, 216) transmitting moving force of the moving member to a member to be actuated (10b, 30b) as an actuating force. The moving member is moved towards the supporting member by magnetic force generated by applying an electric current to the electromagnetic coil to apply the actuating force to the member to be actuated via the actuating force transmitting member. The electromagnetic coil includes a plurality of electromagnetic coils provided at the supporting member.
摘要:
Device for preventing gear hopout in a tooth clutch in a vehicle transmission, said tooth clutch comprising an engaging sleeve (117, 217, 351, 551) having sleeve clutch teeth (118, 218, 718, 818, 918) that can selectably be brought in and out of an engaged state with mating clutch teeth (119, 319) by means of axial displacement of said engaging sleeve. Axial displacement is carried out by a shift actuator system (125-126-127, 525-526-527) . The shift actuator system is activated at some cases when said tooth clutch is in said engaged state in order to prevent gear hopout.
