A slide-out unit drive assembly for a vehicle body having an opening formed in an exterior wall and a reciprocable slide-out unit disposed in the opening and slidable between a retracted position and an extended position. Sliding movement of the slide-out unit is controlled by the drive assembly at least partially arranged within the jambs. The drive assembly may include one or more drive cables extending connected to the slide-out. The drive assembly may include drive chain that actuates one or more of the drive cables, or the drive assembly may include a drive nut that actuates one or more of the drive cables, or the drive assembly may include a block and tackle assembly that actuates one or more of the drive cables. Sliding movement of the slide-out unit may be either motor driven or manually powered.

A steering system of a vehicle includes a toothed rack which is connectable to wheels of the vehicle to turn the wheels, a steering drive for displacing the toothed rack with a motor unit and a gear unit where the gear unit is connected to the toothed rack and converts a rotation of the motor unit into a displacement of the toothed rack, and a force transmission element disposed between the motor unit and gear unit. The force transmission element has a core element and a covering element which at least partially surrounds the core element. The core element has a greater strength than the covering element and has protruding regions for producing a positive-locking connection with respect to the motor unit and the gear unit and has connection regions which connect the protruding regions. The covering element is in direct contact with the motor unit and the gear unit.

A transfer case for use in a four-wheel drive vehicle and having a clutch assembly disposed on a front output and a pass-through rear output arrangement. The front output is a front output shall. The rear output is established by directly interconnecting a transmission output shaft to an end segment of a rear propshaft. A transfer assembly is driven by the transmission output shaft and can be selectively coupled to the front output shaft via the clutch assembly.

The wheel assembly includes an arm 51, a wheel 55, a power supply port 60, an electric motor 56 coupled to the wheel 55, and a motor controller 62 for controlling rotation of the electric motor 56. The method of controlling the motion of a motorised object includes defining a target position, sensing a current position of the motorised object and using an output from a processor to control the electric motors to drive the object toward the target position. The golf club storage and transport device 70 includes a body 71 for storing golf clubs and a pair of releasable wheels 75. The device 70 has an assembled configuration and a disassembled configuration.

A polygon compensation coupling system (30; 40; 60) comprises a first rotatable element (31; 41; 61), a second rotatable element (32; 42; 62a, 62b), and at least one linkage coupling the first rotatable element (31; 41; 61) with the second rotatable element (32; 42; 62a, 62b). The linkage comprises at least one first coupling element (34a; 44a; 64a) pivotably coupled to the first rotatable element (31; 41; 61) and at least one second coupling element (34b; 44b; 64b) pivotably coupled to the second rotatable element (32; 42; 62b). The first and second coupling elements (34a, 34b; 44a, 44b; 64a, 64b) are pivotably coupled to each other at a hinge point, the hinge point is configured to move along a compensation curve varying the coupling between the first rotatable element (34a; 44a; 64a) and the second rotatable element (32; 42; 62b).

There is presented various embodiments disclosed in this application, including an improved crankshaft system using a load connecting member which provides a greater maximum torque angle than a conventional system, thereby improving efficiency and power.

The invention is a rack and chain lifting device. The purpose is to convert rotational motion to linear motion in a way that is superior to a rack and pinion device because, first, it allows for more points of contact with the rack through the use of a silent chain in place of a pinion, and, second, because it can be used in corners since the motor can be distanced from the rack by means of the silent chain. The invention comprises a silent chain with link plates that are shaped such that the teeth of the link plates are offset when the chain is straightened, allowing the profile of the silent chain to correspond with the profiles of both gears and racks. The invention also comprises a rack that can be placed in corners. Some embodiments include a system of gears, a motor, and a mounting platform.
