摘要:
A DOHC engine of the V-type has two cylinder heads each detachably secured to a cylinder block. A crank shaft on the block drives two intermediate shafts, one on each cylinder head, by means of an endless flexible element. An additional flexible endless element is provided in each cylinder head to drive two cam shafts from the intermediate shaft on that cylinder head. Each endless flexible element together with its toothed pulleys or sprockets and its timing belt or chain is described as a wrap-around transmission.

Disclosed is a network monitoring method including: a predicted amount of rainfall obtaining step of obtaining a predicted amount of rainfall generated in a predetermined time in a current line route; a prediction step of predicting whether or not a line failure occurs in the current line route caused by the predicted amount of rainfall assuming it rains actually in the current line route with an amount of rainfall substantially equivalent to the predicted amount of rainfall in the predetermined time in the current line route; and a change instruction step of instructing the radio communication network to change the current line route into a different line route on which it is predicted that no line failure caused by rainfall occurs and to control the radio communication network to change the current line route into the different line route, before the predetermined time passes.
摘要:
A pulley, composite in nature, including a fabricated wheel defining a rim channel into which a ring is positioned. The ring is rigidly held within the channel by tabs and interlocking arrangements. The ring is designed to include any one of a number of pulley gripping surfaces such as teeth and V grooves.

Proposed in this application is a device for attenuating vibrations in a drive shaft of a motor vehicle of a type, in which driving force of an engine is transmitted to both left and right drive shafts through a clutch, a transmission mechanism, and differential gears. This vibration attenuating device is constructed with a vibration absorbing device having a resilient member and a weight combined together as an integral whole, and both members are provided at one of the drive shafts having a length longer than the other to the end part thereof where wheel is to be fitted.

A cylinder block for an internal combustion engine includes the skeleton frame formed of metal and a waterjacket surrounding the frame formed of a heat resistant plastic. The engine includes a cylinder head and the cylinder bearing supports and a sleeve forming a cylinder bore. The engine block, cylinder head and main bearings are fixed together with bolts which pass through portions of the framework parallel to the metal sleeve. The engine also includes an air intake pipe with the portion of the pipe adjacent the waterjacket integrally formed with the waterjacket.

A rubber composition comprising 100 parts by weight of an ethylenically unsaturated nitrile-conjugated diene high-saturation copolymer rubber containing 20 weight % or less of conjugated diene units, and 1-100 parts by weight of an unsaturated carboxylic acid metal salt having the general formula: ##STR1## wherein R and R' represent aliphatic or aromatic hydrocarbon groups or a hydrogen atom, which may be the same or different from each other, Me represents a metal selected from the group consisting of Be, Mg, Ca, Sr, Ba, Ti, Cr, Mo, Mn, Fe, Co, Ni, Cu, Ag, Zn, Cd, Hg, Al, Sn, Pb and Sb, and n is an integer of 2-4.
摘要:
A power transmitting apparatus that includes an engine, a transmission disposed alongside of the engine in juxtaposed relation; and gears, a chain, a belt, or the like operatively coupling the output shaft of the engine and the input shaft of the transmission. The transmission comprises a countershaft-type transmission having, in addition to the input shaft, a countershaft and an output axis of rotation which extend parallel to the input shaft. The countershaft is disposed more closely to the engine than a plane which passes through the input shaft and the output axis of rotation of the transmission. Preferably, the output shaft of the engine and the input shaft of the transmission are operatively coupled with a resilient belt trained around a drive pulley coupled to the output shaft of the engine and a driven pulley coupled to the input shaft of the transmission.
摘要:
A tensioner acting on and allowing an endless transmission belt, stretched between a driving wheel and driven wheels supported on the body of an internal combustion engine, to run under a constant tension, wherein an oscillating lever supports a tension pulley pressed against a loosening side of the transmission belt and has a base end pivoted on the engine body, and an automatic adjuster connected to a tip end of the lever is supported on a case for a hydraulic pump of the engine. A spacer is interposed between contact portions of the oscillating lever and the engine body, and an outlet of the pump and an oil port of the adjuster are directly communicated. An adjusting screw is provided on the tip end of the oscillating lever and is operatively connected to the upper end of a plunger of the automatic adjuster. An auxiliary spring is further connected to the oscillating lever to assure the transmission belt of the constant tension, and the tension pulley supported on the oscillating lever is pressed against the transmission belt at a location close to the axis of an engine cylinder, that is, almost directly above the driving wheel, to thereby secure a sufficient space for installation of the automatic adjuster outside the pulley.
