AI Technical Summary
Existing tensioners for motor vehicle accessory drives are heavy and expensive, and existing solutions are unsuitable for applications with packaging constraints or do not optimally manage the forces acting on pulleys due to the use of reversible electric machines.
A tensioner design using two rigidly connected arms with a working arm and a spring to transmit load from the taut span to the slack span, incorporating a spring to filter tension peaks, reducing overall dimensions and weight while maintaining optimal tensioning.
The design achieves reduced weight and cost by optimizing structural dimensions, allowing for efficient tensioning without additional space requirements and filtering tension peaks, thus enhancing the belt's operational stability.
