摘要： Where the components are to be connected together in an assembly the bores (28,30) of each part (14,16) are in a straight line. A connecting bolt (10) has a shaft (32) with an enlarged section (34) and insert section (36). The enlarged section has a larger cross section than the bores. The length of this enlarged section (34) is such that the section extends through the bore (28) in one part (14) and through a sufficient axial section of the bore (30) in the other part to hold the parts together, whilst allowing easy release of at least the other part from the enlarged section. The enlarged section is pref. made of a deformable material to facilitate its insertion into the bores.

摘要： An open-loop clutch-to-clutch shift control system wherein the overlap between off-going and on-coming clutches in an upshift is regulated in accordance with a confidence term determined through a self-estimation by the control system of its ability to accurately determine the on-coming clutch fill time, and thus, its ability to effect a precise exchange of the off-going and on-coming clutches with little or no overlap. Under certain conditions, the confidence level is assumed to be low, and the clutches are controlled to result in a relatively high level of overlap. As the level of confidence improves, the timing of the clutch exchange is adjusted to reduce the level of overlap. When the level of confidence is high, the exchange of clutches is effected with almost no overlap.

摘要： SERVO SHIFT CONTROLLER FOR A FORWARD/REVERSE MECHANISM A mechanical clutch is provided to selectively interconnect a forward or reverse gear member to a transmission shaft. The clutch is operated by a servo piston and fork structure. The servo piston is slidably disposed in a housing and urged in the forward select position by a spring. The housing and servo piston cooperate to define two fluid chambers which are maintained in a separated condition when the forward select position is established. One chamber is in fluid communication with a fluid system that is controlled to provide fluid at two distinct pressure levels, depending upon various vehicle operating parameters. The other chamber is connected with a selectively engageable fluid operated friction clutch which is effective to assist in establishing at least the reverse drive ratio within the transmission. The lowest level of fluid pressure in the one chamber is not sufficient to cause the piston to overcome the spring force and thereby move the clutch to the reverse select position. The second pressure level is, however, sufficient to cause such movement. In the reverse select position, the chambers are fluidly interconnected and the fluid clutch can be engaged by the fluid pressure supplied through the second chamber from the first chamber.

摘要： A motor vehicle having a battery supported on a cantilevered tray within the vehicle's engine compartment wherein the vibrations otherwise experienced by the unsecured distal end of the tray is dampened by a substantially rigid bracket which engages the distal end of the tray, overlies the battery so as to retain it in the tray and also engages a vehicle body member. The damper-retaining bracket is preferably integral with an enclosure which encompasses the battery and shields the battery from engine compartment heat. The enclosure will preferably comprise hollow walls for also insulating the battery from such heat.

摘要： SHIFT FORK FOR A VEHICULAR TRANSMISSION The present invention relates to a shift fork (10) for a vehicular transmission. The shift fork (10) utilizes a hub portion (12) from which an offset arm (16) extends radially outwardly to terminate in an outer end portion (18). One or more contact pads (22 and 44) are supported from the outer end portion (18) of the offset arm (16), and the tines (20) extending from the offset arm (16). The contact pads (22 and 44) present longitudinally facing wear surfaces (24 and 46). Each of the longitudinally oriented wear surfaces (24 and 46) has an angularly inclined portion (32 and 48). The inclined portions (32 and 48) each diverge outwardly at an angle (phi or theta) which equals the angle at which the offset arm (16), or each tine (20), deflects at the location along the contact pads (22 and/or 44) where each wear surface (24 and/or 46) is subjected to a predetermined load.

摘要： A neutral-reverse shift control actuator is provided in a transmission. The actuator is operatively connected through a resilient detent mechanism (132-144) to a forward shift control mechanism (146,80). During a neutral-reverse shift manoeuvre, the drive connection partially manipulates the forward synchroniser, such that synchronisation between the input and output shaft is achieved during a reverse shift manoeuvre.

摘要： A shift pattern control for a multiple speed ratio transmission wherein an inference-based control overrides the normal shift pattern to automatically achieve manual pulldown operation under conditions for which such operation would be advised and expected. The inference-based control is achieved with a fuzzy logic technique by which vehicle parameters influencing the desirability of manual pulldown operation are measured or estimated, and used to establish an aggregate measure of the overall need for engine braking and downshifting. In the preferred embodiment, the fuzzy logic parameters include vehicle speed, grade load, engine throttle position, time of braking and time of deceleration. The parameters are applied to membership functions to indicate the truthfulness of the specified conditions, and logical combinations of the truth indications are formed, weighted to reflect their criticality, and combined to form an aggregate measure of the overall need for pulldown operation.
