A chain for a timing drive or an assembly drive of a drive device of a motor vehicle, which has a plurality of link packs articulatedly connected to one another and formed from middle links and cover links, with corresponding recesses through which chain pins or chain sleeves are inserted, and a plurality of inner links which connect the link packs to one another. At least the inner links and the middle links have different expansion behavior.

Chain for a timing drive or an assembly drive of a drive device of a motor vehicle

An internal combustion engine () having a crankshaft (), having at least one camshaft () for actuating gas exchange valves (), and having a synchronous drive () which transmits the rotation of the crankshaft () to the camshaft (), wherein the crankshaft () is arranged predominantly in the first chamber () which is separated in a fluid-tight manner from a second chamber () in which the synchronous drive () is arranged, wherein the camshaft () is also arranged in the second chamber ().

Internal combustion engine having two lubricating chambers separated from one another in a fluid-tight manner

A method for producing pins for a control chain, which has link plates that are connected to each other by the pins. The pin ends are arranged in receiving bores arranged inside the link plates. The pin is made of steel of the type 100Cr6 or 32MnCrMo6-4-3, subjected to a carbonitriding method and has a wear zone between the 1/30 and the 1/60 part of the diameter thereof after abrasive removal on the carbonitrited pin surface.

Method for producing a control chain

A belt drive is provided which includes a circulating belt () which is driven by at least one drive element () and which drives at least one driven element (). At least one first tensioning device () acts upon the belt () in the slack strand and at least one second tensioning device acts in the tightened strand. To prevent or reduce jumps and/or transverse oscillations of the belt (), the second device () guides the belt () and at least one third device () which is arranged radially inside the belt drive, which is suitable, optionally, limits deviations of the belt (). The second device () also tensions the belt () in such a manner that it is subjected to a force (F) which is smaller than the force (F) which is oriented counter thereto during the operation of the belt () on the second tensioning device ().

Wrap-around drive

A hydraulic tensioning system () for an endless drive () of an internal combustion engine (). In an operating mode, the piston () of the tensioning system (), which is supplied with a hydraulic fluid, is supported against a tensioning rail () with a non-positive fit, with the rail pre-tensioning the traction drive element (). If the hydraulic fluid in the tensioning system () is not sufficient, the tensioning rail () is supported on an elastic end stop () of the system ().

Hydraulic tensioning system

In a chain drive for an internal combustion engine, said chain drive comprising a driving wheel (), a driven wheel (), an endlessly circulating chain () that connects the driving wheel () and the driven wheel (), a chain tensioner () acting on the slack strand () of the chain (), and an additional tensioning device () that is loaded by a spring () and acts on the tight strand () of the chain () while being arranged for pivoting, a further driven wheel () is installed in the tight strand () of the chain drive and is used as a driving wheel for a rotatably mounted compensating shaft for offsetting free forces and moments that occur during operation of the internal combustion engine.

Chain drive for an internal combustion engine

A tensioner for a chain, includes a tensioner piston bearing upon a chain and guided by a cylinder for movement in the direction of the chain. The cylinder and the piston define a pressure chamber for receiving hydraulic fluid, wherein hydraulic fluid is able to escape from the pressure chamber via a leakage gap. A control member is provided to at least reduce the leakage gap in size, when a pressure in the pressure chamber increases.

Chain tensioner

A chainwheel ( ) of a control mechanism of an internal combustion engine, said chainwheel being formed in one part or a plurality of parts from at least one hub ( ), a toothed rim ( ) and a wall ( ) connecting the hub ( ) to the toothed rim ( ), provided with at least one means for the damping of vibrations and noises which consists of a noise-damping material.

Chain wheel with damping

A tensioner for a driving member includes a piston (,) guided slidably in a housing (,) and spring-loaded against the driving member. The tensioner further includes a damping device (,) for damping movements of the piston through discharge of hydraulic fluid, such as engine oil, from a pressure chamber (,) via at least one leak gap (,) of the damping device (,). A simple and economic implementation of the leak gap is assured by arranging a rotationally symmetrical body such as a cylinder (,) in a receptacle (,) of the damping device (,), so that the leak gap (,) is formed between the wall (,) of the receptacle and the peripheral surface of the rotationally symmetrical body (,).
