摘要:
Traction mechanism drive for an internal combustion engine, having a crankshaft gear wheel, at least one gear wheel which is arranged on a driven shaft, a wrap-around means and an electric machine which can be actuated in order to reduce rotational non-uniformities, the electric machine (9, 10) having a rotor (12) which is arranged on the or a camshaft (1, 11) and interacts with an immobile stator (15).
摘要:
The invention relates to a wraparound drive for an internal combustion engine, having a wraparound means (2) which is configured as a belt or a chain and is guided over drive and output wheels (3, 5, 6) of the crankshaft (4) and at least one camshaft (7, 8) of the internal combustion engine and/or auxiliary assemblies which are to be driven. In order to ensure reliable balancing of the drive by elimination of oscillations and resonances, there is provision for at least one of the drive or output wheels (3, 5, 6) or a deflection wheel (9) to be of unround or eccentric configuration, and/or for at least two tensioning rollers (11, 13) to be provided, one of these tensioning rollers (13) being provided with a damping device (14), or both tensioning rollers (11, 13) being coupled to one another by a damping device (14).

The invention relates to a rail (16a) of a flexible drive, which rail (16a) is intended to guide a drawing means (2). A lubricant which is introduced into the rail (16a) via the lubricant channel (13) brings about a pressure gap (15) which is formed between the inner side of the drawing means (2) and a guide face (9) of the rail (16a). Direct contact of the drawing means with the rail (16a) is suppressed on account of the lubricant which is introduced into the pressure gap (15), which has a friction-reducing effect.

摘要:
A tensioning device for chain or belt drives, with a cylindrical tensioner housing (33), whose inner surface is constructed as a guide bore (34), in which a piston (35) is guided, with a compression spring (37) acting on the piston, which can move axially in the chain tensioning direction, and with a latch system (39) limiting the return stroke of the piston (35) in the tensioner housing (33). An additional elastic element, which acts in the axial direction and on which the tensioner housing (33) is supported, is arranged in front of or behind the tensioner housing (33). The additional elastic element is formed by a second compression spring (46) arranged in an additional cylindrical housing (48), with the tensioner housing (33) being inserted into the additional cylindrical housing (48) from one end.

A one-way transmission with a resetting function for use in ratchet mechanisms. The resetting spring for the actuating lever is arranged to also takes over the prestressing of the one-way transmission element. The integration of the following switch components is also possible; the shift lever and the one-way transmission element; the shift lever, the one-way transmission element and the resetting spring; the positioning device and the positioning pawls; of the positioning device and actuating button; the actuating button and the resetting element; and the positioning device, the actuating button and the resetting element.

A gearshift for bicycle gears includes an operating lever arranged so as to be rotatable around a stationary central axis for controlling an operating part arranged in a housing. The operating part is also rotatable around the central axis and has a take-up groove for receiving a gear-shifting cable, whereby a latch interacts with a tooth mechanism on the operating part for winding the cable. The gearshift further includes a release-and-hold mechanism consisting of a first latching disk having a first latching segment and a second latching disk having a second latching segment connected to the operating part, and of a release lever that interacts alternately with the first latching segment and the second latching segment. Arranged on the release lever are a first latching lug and a second latching lug, which alternately engage with the first latching segment and the second latching segment. The release lever is mounted pivotally about a rotational axis arranged substantially perpendicularly relative to the central axis in a stationary fashion. An advantage of the invention lies in the simple operability of the operating lever and the release lever, whereby attention has been given to the ergonomics of the lever that the bicycle gear can be shifted under any circumstances, even when the operating hand of a bicyclist is being used for operating a brake lever.
摘要:
In spite of the absence of a pullout fuse block, functional elements comprising simple socket-type connectors come into contact with an external cable in a mechanically and electrically reliable manner, when said cable has a rod-type or sword-type mating connector which engages directly in the connector by means of a radially protruding return baffle, in a sealed manner, through the rear of an opening in the wall of a housing. If, during the plug-in action, an injection-molded skin which first at least partially closes the opening is enlarged or perforated, the breaking edge nestling against the envelope surface of the mating connector in the plug-in direction provides another retraction block with additional sealing and vibration damping.

A traction mechanism that includes at least one guide (1, 1′-1′″″) for tensioning or guiding a continuous traction drive element, especially a chain of the control drive of an internal combustion engine is provided. The guide (1, 1′-1′″″) is made of plastic and metal inserts and has a double T cross-section having an upper member (3) and a lower member (4) that are connected by a central web (5) and ribs (6) arranged endwise on both ends of the web (5). The invention provides a rigid, compact and inexpensive guide. For this purpose, the guide (1, 1′-1″″″) includes two lateral plates (2, 2′-2′″″, 18, 19), preferably made from steel, that are inserted into recesses (7) in the side faces (29) of the ribs (6) in a play-free manner and are held in position by form fitting fastening elements.
