A system and method capable of detecting damage in a belt before catastrophic failure of the belt occurs. The system includes a belt having at least a first conductive component and/or at least a first dielectric component, and one or more pulleys to which the belt is mounted. At least a first of the pulleys has at least one conductive component that, in combination with the first conductive component or the first dielectric component of the belt, defines an electrical element. At least a portion of the electrical element is located within the belt so as to be physically responsive to transitory and permanent distortions of the belt resulting from extrinsic and/or intrinsic sources. Electrical potential is applied through the electrical element so as to generate an electrical signal from the electrical element corresponding to a physical response of the belt to a transitory and/or permanent distortion.

The present disclosure discloses an apparatus (100) for eliminating slack and vibrations of the chain (400) comprising a piston-cylinder arrangement. A first piston (10) is configured to be displaced inside the cylinder (20) of the piston-cylinder arrangement and a second piston (30) is configured to be displaced inside a cavity (40) defined inside the first piston (10) with the axis of the cavity (40) being coaxial with the axis (A) of the cylinder. A lubricating oil passage (50) defined to pass through the first piston (10), the second piston (30) and the cylinder (20) of the piston cylinder arrangement. The apparatus facilitates reduction in vibrations, slack elimination and automatic lubrication of the chain drive.

A method of performing regular maintenance in a hybrid drive module, comprising a housing (170) enclosing a continuous member drive (120) comprising a chain or a belt (126) connecting an electrical motor (110) with a crank shaft (22) of an associated internal combustion engine (20) via at least one coupling (130, 140), said electrical motor (110) being fastened with respect to the crank shaft (22) via fastening elements (111) wherein said method comprises: unfastening the electric motor (110) from said motor's (110) fastening elements (111); positioning the electric motor (110) such that the crankshaft (22) is a distance (d) from the electric motor (110) and such that tension in the chain or belt (126) is at or above a pre-specified level; and re-fastening fastening elements (111) such that the electric motor (110) is maintained at the distance (d) from the crankshaft (22).

A swing arm suspension for suspending a rear drive wheel in a three-wheeled electric vehicle has an adjustable arm which allows the tension on the drive belt to be easily adjusted for installing or removing the drive belt or adjusting tension for operation.
