Abstract: An apparatus for transmitting torque between the output element of an internal combustion engine and the input element of a variable-speed transmission in a motor vehicle has a first flywheel which is screwed or bolted to the output element and a second flywheel which is coaxial with and rotatable relative to the first flywheel and is connected to the input element by the clutch plate of a friction clutch. One or more dampers are provided in a lubricant-containing annular chamber of the first flywheel to oppose rotation of the flywheels relative to each other, and each damper has an annulus of arcuate coil springs acting in the circumferential direction of the flywheels. The cover of the clutch has stressing arms which extend into the chamber and engage the springs.

Abstract: A backing plate for connection to a clutch disc includes a pair of spaced friction material portions (or pads). A central channel extends between the two portions to allow air to flow over and cool a central area of the friction material. Clearances are defined at radially inner and outer areas of the channel and receive rivets to secure the backing plate to a clutch disc. The rivets are positioned radially between the radially inner and radially outer edge of the friction material, such that the backing plate is firmly secured to the clutch disc to prevent bowing. The improved backing plate ensures that the backing plate remains firmly secured to the clutch disc, and that the friction material is adequately cooled such that it efficiently transmits rotational forces from a drive source to a driven shaft.

Abstract: An apparatus for transmission of torque between the crankshaft of an engine and the input shaft of a variable-speed transmission in a motor vehicle has a primary flywheel with a membrane which is connectable to the crankshaft, a secondary flywheel which is connectable to the input shaft by way of a friction clutch, a damper with circumferentially acting coil springs in an annular chamber of the first flywheel radially outwardly of the membrane, and torque transmitting arms which are carried by the second flywheel and alternate with the coil springs of the damper. A slip clutch can be installed between the torque transmitting arms and the second flywheel to limit the magnitude of transmittable torque.

Abstract: A one-way clutch comprises a plurality of rollers, a retainer having the same number of roller pockets as rollers, a cylindrical shell having the same number of cam grooves as rollers, and springs for normally biasing the rollers toward the cam grooves. The cam grooves are provided at the axially intermediate portion of the shell. The shell is provided at one end with a radially inwardly-turned flange and at the other end with a cylindrical boss portion having a smooth inner surface free of cam grooves. The retainer includes a pair of annular portions at either end and an axially intermediate portion provided with roller pockets. The annular portion which is inserted into the boss portion of the shell has a smooth cylindrical outer surface dimensioned to be pressingly fitted to the boss portion. Thus there are no gaps between the retainer and the shell at the boss portion of the shell, thereby sealing that end of the shell and preventing the outflow of grease and the entry of dust.

Each of the friction rings includes a rigid backing plate having a first friction element secured to one face thereof and a second friction element secured to opposite face thereof. The first friction elements are formed from a material having a relatively low coefficient of friction, while the second friction elements are formed from a material having a relatively high coefficient of friction. Retainers are provided for retaining the friction rings to the flywheel and the pressure plate, while permitting restricted relative rotational movement therebetween.

Abstract: An IC engine is connected via a clutch with a change-speed transmission. A sensor responding to a gear selection informs the electronic control circuitry in which gear the vehicle is traveling. The rotary part of a tachometer is provided at the output of the transmission and is in cooperation with the sensor part of the tachometer, which feeds a signal to the electronic control circuitry. A universal joint shaft runs from the output of the transmission to the axle transmission, which is connected via the axles to the drive wheels. The rotary tachometer elements, connected with the drive wheels, are in cooperation with the tachometer sensors, whose output signals are supplied to the electronic control circuitry and compared therein with a calibration value. Such comparison determines the optimum clutch engagement time for the respective travel and loading condition of the vehicle.

Abstract: Apparatus for transmitting torque from the output shaft of the engine to the input shaft of the variable-speed transmission in a motor vehicle has a primary flywheel which is connectable to the output shaft, a secondary flywheel which is connectable to the input shaft by engaging a friction clutch, and one or more dampers which oppose rotation of the flywheels relative to each other. The flywheels define an annular chamber for the damper or dampers, and such chamber surrounds two closely adjacent portions of the flywheels which define a radially extending clearance for the flow of cooling air. The radially inner portion of the chamber is separated from the clearance by an annular seal which is located at most midway between the radially innermost and radially outermost portions of an annular friction surface on the secondary flywheel. Such friction surface is adjacent one friction lining of a clutch plate forming part of the friction clutch and being connectable to the input shaft of the transmission.

Abstract: A conventional lock-up solenoid having a long delivery tube and mounting bracket with outwardly extending mounting legs is mounted on a transmission torque converter case requiring a lock-up solenoid with a short delivery sleeve. This is accomplished by a spacer member constituted by a pair of spacers carried on threaded studs which are received in the tapped holes. In effect, the spacer shortens the long delivery tube so that it fits the space of a short delivery tube lock-up solenoid. If the transmission is one requiring a long delivery tube, it is installed without the spacer and as any other replacement lock-up solenoid.

Abstract: An electromagnetic coupling device is proposed to obviate several drawbacks in the conventional devices, namely, to prevent loose fixing in axial direction which gives rise to undesirable rotation of the rotary shaft following the rotor, to reduce the production cost due to the use of magnetic pole in the rotor, to reduce lengthy lengthy assembly work brought about by many fixing rings and to prevent slipping out of the hub and the rotary shaft encountered in the conventional coupling devices.In order to obviate the drawbacks encountered in the conventional coupling device, a rotor retainer is placed around the rotary shaft to urge a rotor against a hub, in addition, the rotary shaft is provided with fixing portions of a minimum number, such as axially extending legs at least one of which is attached with a claw, stepped portions, a groove and so forth for preventing slipping out of the rotary shaft, hub and driven shaft.

Abstract: A clutch control device comprises a rotatable driving member to which one end of a traction cable is circumferentially attached, the traction cable having a coupling piece at its other end. The control device also includes a sleeve member which is in telescopic engagement with the coupling piece, with releasable locking means arranged between the sleeve member and the coupling piece. The sleeve member is arranged for connection to a control linkage, leading for example to a clutch pedal; and the control device also has a spring which urges the sleeve member towards the coupling piece. Any wear occurring upstream of the device, for example in the associated clutch, is automatically taken up due to the provision of resilient preloading means which tend to maintain the traction cable under tension and which act between the fixed support or housing member of the assembly and the coupling piece, which is thereby biassed towards the sleeve member.
