180352000 | With lateral support between the differential or axle housing and the vehicle frame | 1 |
20120067663 | ADAPTER FOR A CORVETTE REAR DIFFERENTIAL - An adaptor for an older Corvette drive train provides a structure for coupling the drive shaft extending from a front-mounted transmission to the differential of a C5 or C6 Corvette rear suspension in which the rear mounted transmission has been removed. A housing holds a stub shaft for rotation on front (outside) and rear (inside) bearings. The shaft has a coupling yoke mounted to its front end and engages the differential gearing at its other (rear) end. The housing mounts to the differential at the five mounting points of the removed transmission. A bracket which attaches to frame mounts can be mounted to either the top or bottom front (outside) face of the housing, depending upon the suspension-to-frame geometry. A circular flange on the shaft positions and holds the inside bearing and a rearward extending boss on the yoke positions and holds the outside bearing. A crushable tubular spacer fits over a portion of the shaft and holds the front and rear bearings apart during assembly and while the shaft assembly is drawn up. Two grease ports and fittings access the interior of the peripheral sealing ring to meet and seal the differential opening. | 03-22-2012 |
180357000 | Belt or chain drive | 3 |
20100212993 | Belt driven wheel support and suspension system on a personal wheeled vehicle - A belt drive and wheel support and suspension system for a personal wheeled vehicle has a drive pulley for fixed attachment to a rotating power source and a driven pulley for fixed attachment to a wheel of the vehicle. Each of the drive pulley and the driven pulley have a belt engagement face including a plurality of cogs arranged at an oblique angle on the belt engagement faces. An endless belt extends between the drive pulley and the driven pulley and has a plurality of cogs affixed to an inner face of the endless belt that are arranged at a like oblique angle with respect to the cogs on the drive and driven pulleys for positive intermeshing engagement with the cogs on the pulleys. A suspension arm is coaxially supported with the drive pulley and is pivotally moveable about a rotation axis of the rotating power source. An opposite end of the suspension arm is connected to the vehicle by a shock absorbing member and rotatably supports the wheel and driven pulley to thereby allow upward and downward movement of the wheel and driven pulley while maintaining the belt in positive engagement with the drive and driven pulleys. | 08-26-2010 |
20110203867 | CHAIN GUIDE DEVICE - A chain guide device wherein it is unnecessary to make a chain guide body a thick and heavy member to enhance the productivity of the chain guide body. The chain guide body is split into a left guide half having a left-side upper split surface and a left-side lower split surface which are formed along a longitudinal direction of a chain and a right guide half having a right-side upper split surface and a right-side lower split surface. The guide bodies, which are roughly U-shaped, can be easily demolded after injection molding to enhance productivity. The contact of the chain with the split surfaces is lessened, as compared with the case where split surfaces are inclined at an angle relative to the longitudinal direction of the chain. Accordingly, wearing of the split surfaces is restrained, and it is unnecessary to make the chain guide body greater in thickness and weight. | 08-25-2011 |

180359000 | With sprung differential | 1 |
20150360562 | DIFFERENTIAL ASSEMBLY AND METHOD - A vehicle differential inversion assembly for splitting the torque of the vehicle power source two ways to opposite sides of the vehicle, to a set of wheels; a left wheel and a right wheel. The wheels are supported by respective independent left and right suspensions allowing vertical travel of each wheel. The assembly features a differential module for splitting the torque two ways. The differential module is disposed between the left wheel and the right wheel and has a left side output and a right side out-put. The outputs spin at opposed directions. A left output axle couples with the left side output and extends to the left of the differential module. A right output axle couples with the right side output and extends to the right of the differential module. A left wheel axle is cross-coupled with the right output axle by a right inversion joint disposed at a distance to the right of the differential module. The left wheel axle extends toward and turns the left wheel. A right wheel axle is cross-coupled with the left output axle by a left inversion joint disposed at a distance to the left of the differential module. The right wheel axle extends toward and turns the right wheel. The right inversion joint and the left inversion joint provide for angular articulation of the left wheel axle and the right wheel axle, respectively, thereby allowing the vertical travel of each wheel. | 12-17-2015 |
