Abstract
An internal combustion engine having a power generating device, and a transmission link connecting the power generating device to an accessory operated by the power generating device, the transmission link being tensioned by a tension adjusting device which elastically presses a tension pulley against the flexible transmission link by the electric deformability of a deformable parallelepiped solid constituted by a pair of elements formed of composite flexible strips held parallel, and separated, by the permanent fixing of their extremities in a bearing holder block and in an adjustable fastener, the flexible strips possibly supporting a means to modify the flexibility of the elastic tension device which may include a means to damp the vibrations of the flexible link.
Claims23
An internal combustion engine comprising:
- mechanical power generating means for generating mechanical power;
- first wheel device being connected to and receiving mechanical power from said mechanical power generating means;
- second wheel device positioned in spaced apart relation to said first wheel device, said second wheel device being connected to and receiving at least a portion of said mechanical power from said first wheel device;
- belt means having a surface, said belt means being connected between said first wheel device and said second wheel device for transferring mechanical power from said first wheel device to said second wheel device by mechanical friction;
- belt tensioning means for being in contact with said surface of said belt means for adjusting the tension of said belt means by applying a controlled amount of force to said surface of said belt means, said belt tensioning means comprising:
- mounting means for being mounted on a first surface, said mounting means for supporting said belt tensioning means;
- resilient member means connected to said mounting means;
- movable member means connected to said resilient member means, said movable member means for being in contact with said belt means, said movable member means being movable relative to said mounting means to alter the tension of said belt means;
- said movable member means comprising means for applying pressure to said belt means;
- said resilient member means for receiving a rocking force and applying a rocking counter force between said mounting means and said movable member means when said movable member means is moved relative to said mounting means;
- and
- said resilient member means comprising at least two flexible arms, said at least two flexible arms being spaced apart from one another.
A belt tensioning device for tensioning a belt of a power transmission device, said belt tensioning device for being in contact with a surface of a belt for adjusting the tension of the belt by applying a force to a first surface of the belt, said belt tensioning device comprising:
- mounting means for being mounted on a first surface, said mounting means for supporting said belt tensioning device;
- resilient member means connected to said mounting means;
- movable member means connected to said resilient member means, said movable member means for being in contact with said belt means, said movable member means being movable relative to said mounting means to alter the tension of said belt means;
- said movable member means comprising means for applying pressure to said belt means;
- said resilient member means for receiving a rocking force and applying a rocking counter force between said mounting means and said movable member means when said movable member means is moved relative to said mounting means;
- and
- said resilient member means comprising at least two flexible arms, said at least two flexible arms being spaced apart from one another.
