Patent number: 8591117Abstract: A hydraulic bushing having at least two chambers and at least one channel connecting the chambers. The bushing is made of a high durometer rubber or other polymer to increase durability. The bushing further includes a center bearing press fit in the center of the annular bushing. The bushing is further press fit into an annular seal operable to seal the fluid within the chambers and channels. The bearing, bushing, and seal assembly is then press fit into a bracket which is subsequently mounted to the vehicle. The center bearing is operable to hold the prop shaft wherein the center bearing is free to rotate within the bushing thereby allowing the prop shaft to rotate.Type: GrantFiled: October 21, 2011Date of Patent: November 26, 2013Assignee: Trelleborg Automotive USAInventors: Alain Rene Regis Giraud, Travis Jon Grassmid, Donald Paul Price

Patent number: 6713990Abstract: The invention provides a device for producing electricity intended in particular to be stowed on board a vehicle or a container, including a three-phase alternator able to be driven in rotation at a variable speed by a thermal engine, a rectifier for generating a rectified current form the current delivered by the alternator and a voltage-booster chopper using the self-inductance of the alternator to step up the voltage. The alternator includes six or eight poles and operates with a switching frequency of preferably between 3 and 15 kHz.Type: GrantFiled: August 8, 2000Date of Patent: March 30, 2004Assignee: Moteurs Leroy-SomerInventors: Régis Giraud, Christian Andrieux, Eric Coupart
