Patent number: 7581299Abstract: The invention eliminates the need of handling an engine in a process for assembling a torsion damper which couples the engine with a power transmission system and a torque limiter. In a damper unit with a torque limiter positioned between an output shaft of an engine and a power transmission shaft of a power transmission system, the damper unit includes a fly wheel damper, a torsion damper and a torque limiter. The torque limiter of the damper unit is coupled to the torsion damper with a set load applied thereto such that the torque limiter and the torsion damper are combined to form an assembly. The torsion damper and the torque limiter can be assembled by handling, independently of the engine, only components which are smaller and lighter than an engine. This improves the efficiency of the assembling operation of the damper unit with the torque limiter.Type: GrantFiled: March 25, 2005Date of Patent: September 1, 2009Assignee: Aisin AW Co., Ltd.Inventors: Yoshio Kintou, Yoshihiko Sasaki
