摘要:
A method and system for controlling creep in an automatic transmission, comprising a first creep torque control means which, upon generation of an accelerator- and brake-pedal undepressed state in a running mode, generates a target creep speed, the target creep speed increasing as a function of time and settling to a predetermined value, the first creep torque control means then calculating a creep torque from the target creep speed, detecting a change in vehicle load from a speed deviation, correcting a target creep torque on the basis of the detected change in vehicle load, and controlling the engine torque on the basis of the correction, and a second creep torque control means which controls a transfer torque of a starting clutch (a first friction clutch) on the basis of a slipping speed of the starting clutch and the target creep torque, the creep controlling method and system being able to realize a stable creep running even against a change in running environment such as the existence of a slope or an increase of payload while suppressing wear and heat generation of the friction clutch.

An automatic transmission has a first axis (input axis) 102 for inputting the power, a second axis (output axis or couner axis) 103 for outputting the driving force source, at least one or more first gear group which consists of drive gears 111, 112 fixed on the first axis, and a driven gear 122 provided so as to engage or run idle with respect to the second axis with being engaged with the drive gear, and at least one or more second gear group which consists of driven gears 123, 124, 125 fixed on the second axis, and a drive gear 114, 115 provided so as to engage or run idle with respect to the first axis with being engaged with the driven gear. The automatic transmission further comprises a torque transferring mechanism 140 for transfering the torque between said driven gear which can run idle with respect to the second axis and the driven gear fixed to the second axis.

A mesh type automatic transmission is equipped with a plurality of shift gears arranged to rotate freely to an output shaft for providing driving force to the wheels. Cogged clutches 12, 15 engage with the output shaft. Counter shift gears corresponding to each speed are fixed to a counter shaft rotated by the rotation of an input shaft and mesh with the shift gears for performing automatic shifting by controlling engagement of one of the cogged clutches with the voluntary shift gears determined from the accelerator command value and the vehicle speed. An assist mechanism transmits rotational force of the input shaft to the output shaft via the assist shaft which rotates from the rotation of the counter shaft when no cogged clutch of the plurality of cogged clutches is engaged with any of the plurality of shift gears occurring during switching when an engaged cogged clutch of the plurality of cogged clutches is disengaged and one of the cogged clutch of the plurality of cogged clutches is to be engaged.

A turbo molecular pump comprises an electric component section having a motor, a base section supporting the electric component section, a shaft rotationally driven by the motor, and an impeller connected to the shaft for rotation therewith. A plurality of V-shaped grooves are formed in one or both of the confronting surfaces of the base section and the impeller. A casing houses the electric component section, and a heat insulating material is disposed between the casing and the base section.

This invention pertains to a method of separating iron sheets from washed iron products. The method includes the following steps: crushing wasted iron products into pieces; transporting the crushed pieces on a conveyer; and separating iron sheet pieces from the crushed pieces on the conveyer by virtue of a magnetic separator placed over the conveyer, wherein the iron sheet pieces staying on the conveyer in a standing state are selectively subjected to an upward force. By applying the upward force to the sheet-shaped iron pieces staying on the conveyer, the balance between magnetic and gravitational force is lost and the iron sheet pieces are smoothly attracted by the magnetic separator.

A crane apparatus is disclosed. A hoisting accessory is traversed by rotating rotating drums by driving of a traversing motor to take up or pay out wire ropes. Continuously variable transmissions are provided for changing rotational speeds of the rotating drums. A control device controls the continuously variable transmissions in a gear changing manner so that forces imposed on the drums by the wire ropes will be balanced. Thus, torques acting on the pair of drums are canceled out in all areas in which the hoisting accessory moves, whereby the capacity of the drive motor can be reduced.
