    摘要: A continuously variable transmission (CVT) system, which turns the rear wheels of a lawn mower or similar vehicle at different speeds in a coordinated method with the front steering wheels in order to achieve the best turning radius (including a tight or zero turn radius, if desired) under most conditions. The system comprises two stages: the first stage comprising a Fixed Center Distance CVT pulley system, and the second stage comprising dual CVTs (e.g., left and right) that input into dual gear reducers (left and right), which are mechanically connected to the rear wheels. The second stage dual CVTs (left and right) are synchronized with the steering wheel, thus achieving different rear wheel speeds and/or directions based on the steering wheel position.

    摘要: A ball screw nut (3) in which multiple balls (7) are disposed in rolling tracks configured from shaft-side thread grooves (4A) and nut-side thread grooves (6A), and the threaded shaft (4) or the nut (6) is provided with a deflector member (15) in which multiple circulation grooves that make the rolling tracks into circling paths are formed. In the ball screw nut: one circumferential direction end of at least one of the multiple circulation grooves is disposed at a position that is shifted in one circumferential direction or the other with respect to the one circumferential direction ends of the other multiple circulation grooves. The invention addresses the problem of providing a deflector-type ball screw capable of improving durability with respect to radial loads and moment loads without enlarging the overall shape or providing multiple deflector members.

    摘要: A continuously variable transmission includes a first shaft driveably connected to a power-plant and having a first pair of sheave disks, and a second shaft having a second pair of sheave disks. A tension member is connected to the first and second pairs of disks such that power is transmittable between the first and second shafts. A third shaft is selectively driveably connected to the second shaft via a clutch. The clutch includes an inner race fixed to one of the second and third shafts, and an outer race fixed to a gear and having an inner surface circumscribing the inner race. At least one pawl is biased to couple the races in a fixed relationship for common rotation. The clutch further includes an electric coil and an armature configured to engage the pawl to decouple the races in response to current being supplied to the electric coil.

    摘要: A continuously variable transmission includes an input pulley (1) in which a pair of pulley halves (4) with pulley faces (4a) form a V-groove (6), an input shaft (2) which journals the input pulley (1), and an endless transmission member (5) wound on the input pulley (1). One of the pulley halves (4) of the input pulley (1) has a piston part (16) relatively rotatable with respect to the input shaft (2) and a pulley half disc (13) slidable on the surface of the piston part (16) through the intermediary of a friction reducing part (11) between the piston part (16) and the endless transmission member (5). The pulley half disc (13) is splined to and integrally rotated with the input shaft (2).

    摘要: A utility vehicle provided with an engine in a rear portion of a vehicle body is disclosed. The engine is provided with a cylinder head, and has an exhaust gas outlet port formed to be open in a front surface of the engine. An exhaust pipe extends forward from the exhaust gas outlet port, then curves, and extends rearward. A cover that covers a front portion of the exhaust pipe includes: a front-side portion that covers a front side of the front portion of the exhaust pipe; an upper-side portion that extends rearward from an upper end portion of the front-side portion and covers an upper side of the front portion of the exhaust pipe; and an extension portion that extends rearward from a rear end portion of the upper-side portion and covers an upper side of a front portion of the cylinder head.
