Patent number: 9512909Abstract: An actuator assembly with first and second sleeves, a barrel, a follower, a groove, a spring, and an output member that is coupled to the second sleeve. The first sleeve has a first externally toothed body, a first flange, which extends radially outwardly from the first body, and a first bore. The barrel is received in the first bore and is rotatable therein. The follower is fixed to one of the barrel and the first sleeve and is received in the groove, which is formed in the other one of the barrel and the first sleeve. The second sleeve has a second body with an internally toothed second bore. The second sleeve is disposed about the first sleeve such that internal and external teeth are meshed to axially slidably but non-rotatably couple the first and second sleeves. The spring is disposed between the first flange and the second sleeve.Type: GrantFiled: April 22, 2016Date of Patent: December 6, 2016Assignee: American Axle & Manufacturing, Inc.Inventors: Frederick E.

Patent number: 9353832Abstract: An apparatus with the multi-stage power shifting means applied to a machine tool includes a housing body, a first transmission device and a second transmission device disposed in the housing body, a coupling device connected to the transmission devices and a controller controlling the gear shifting motion of the transmission devices. The controller includes two control units pivotally connected to respective engaging parts of the transmission devices and a driving system capable of moving the control units. When a power is sequentially transmitted from an external power source to the first transmission device, the coupling device, the second transmission device and then to a power transmission mechanism, the controller adjusts the mode of meshing the engaging parts with other correlated elements in the transmission devices to attain different output torque and speed values, the multi-stage shifting effect and the torque multiplying effect without increasing the bulk.Type: GrantFiled: December 10, 2014Date of Patent: May 31, 2016Assignee: Hua Yong Machine Industry Co., Ltd.Inventors: Chao-Kun Hsia, Chien-Jen Ho
