摘要： A power transmission roller assembly includes a power transmission roller configured to be brought into contact with the driving roller and the driven roller, a pivot shaft fixed to a vehicle body, a pivot arm arranged radially inside of the power transmission roller and pivotally mounted on the pivot shaft, and a roller support bearing rotatably supporting the power transmission roller. A pair of biasing members are mounted to the pivot arm and bias the roller support bearing to a predetermined position between the driving roller and the driven roller such that the abutment force between the driving roller and the power transmission roller is balanced with the abutment force between the driven roller and the power transmission roller. Sliding members are mounted on respective shafts of the biasing members to extend through the sliding members, and frictional forces are generated between the sliding members and the respective shafts.

摘要： A drive force distributing device includes first and second rollers rotatable jointly with main a drive wheel system and a subordinate drive wheel system, respectively. Control of the drive force distribution between the main drive wheels and the subordinate drive wheels is performed by adjusting an inter-roller pressing force. A structural body suppresses turning of one of the first and second rollers at a predetermined position. A reference position setting mechanism turns either one of the first and second rollers to turn in one direction, detects a position at which the turn is suppressed by the structural body, and sets a reference position based on the detected position. A turning amount of one of the first and second rollers is detected with respect to the reference position set by the reference position setting mechanism and the control of drive force distributing is performed based on the detected turning amount.

摘要： The invention is directed to a friction wheel drive with a driving roller capable of being driven in a rotary manner, which is mounted on a bearing unit so as to be rotatable about an axis of rotation. The bearing unit is displaceably guided transversely to the axis of rotation, and a circumferential surface of the driving roller can be brought into driving engagement with a friction surface. The bearing unit is coupled to a first mechanical forced guidance system, by which the driving roller, responding to a driving force acting in a first direction, can be automatically pressed against the friction surface with a contact pressing force that increases as the driving force increases. The bearing unit is also coupled to a second mechanical forced guidance system, by which the driving roller, responding to a driving force acting in an opposite second direction, can be automatically pressed against the friction surface with a contact pressing force that increases as the driving force increases.

摘要： A planetary gear comprising a central, rotatable input/output shaft (1a), an elastic outer ring (4) which when being elastically deformed encloses and presses at least three planet wheels (6, 12) in the form of rollers radially against a centrally mounted sun shaft (2), which extends axially in alignment with the input/output shaft (1a). The planet wheels (6, 12) have central holes and are rotatably mounted on stays (7, 13), the centre lines of the stays (7, 13) being parallel with the sun shaft (2). At least two (12) of the planet wheels have substantially coinciding centres with the stays (13) associated with the planet wheels (12), while the planet wheel or other planet wheels (6) as well as the associated stay or stays (7) is/are constructed such that the centre lines of the stays are positioned a given distance closer to the sun wheel (2) than the axes of the planet wheels (6) when the planet wheels (6) engage the sun shaft (2). This results in an optimum transfer of moment, while achieving an accurate positioning of the sun shaft as well as the planet wheel or the other planet wheels against the at least two planet wheels having centres which coincide with the respective stays.

摘要： The automatic friction wheel torque converter enables a bearing-free adjustable force transmission, with different loads and speeds, for example in electric vehicles or machines. Said converter is simple, economical and has a high efficiency. It comprises a pair of friction wheels of which one (8) has a conical annular part and the other one a planar disk (11), a device (5) enabling to move one of the wheels with respect to the other one. Said device is articulated about an axis (16) arranged parallel to the disk and to the cone generatrix of the annular part where said annular part engages said disk. The planar disk may be replaced by a driven cone, in which case the axis (16) is parallel to a generatrix of said driven cone. Elastic members acting on an oscillating frame (2) enable a large number of applications.
