    摘要： A continuously variable transmission steering mechanism of a tracked vehicle, comprising a differential (1), a right drive shaft (2), a left drive shaft (3), and a continuously variable transmission (4) used for adjusting the rotational speed of the right drive shaft (2) and that of the left drive shaft (3). A left half shaft (5) and a right half shaft (6) are connected on the differential (1). The right half shaft (6) of the differential (1) is linked to the right drive shaft (2). The right drive shaft (2) rotates to drive the right half shaft (6) of the differential (1) to rotate. The left half shaft (5) of the differential (1) is linked to the left drive shaft (3). The left drive shaft (3) rotates to drive the left half shaft (5) of the differential (1) to rotate. The rotational speed ratio of the right half shaft (6) of the differential (1) to the right drive shaft (2) is equal to the rotational speed ratio of the left half shaft (5) of the differential (1) to the left drive shaft (6). The employment of the continuously variable transmission steering mechanism of the tracked vehicle, by means of continuously and precisely adjusting the rotational speeds of the left and right half shafts of the differential via the continuously variable transmission (4), implements precise turning of tracks, thus increasing the safety of the tracked vehicle traveling at a high speed.

    摘要： A planetary drive system that has an input and a gear housing that is connected to a speed control system. A cross connecting shaft is drivingly engaged by the speed control system and rotatably connects to a forward and reverse gear set that is drivingly connected to a reduction gear set to provide an output. The speed control system, forward and reverse gear set, and reduction gear set are actuated by band clutch elements that frictionally engage the exterior of ring gears and carriers within the system to control the operation of the planetary drive system.

    摘要： A transaxle comprises: a pair of left and right steerable wheels; a hydraulic pressure source; a pair of left and right variable displacement hydraulic motors, serving as first and second hydraulic motors for driving the respective steerable wheels, wherein the first and second hydraulic motors are fluidly connected in parallel to the hydraulic pressure source, and wherein the first and second hydraulic motors are provided with respective movable swash plates; and a motor control linkage for simultaneously moving both the swash plates of the first and second hydraulic motors according to a turning angle of one of the steerable wheels. The motor control linkage includes a first pivot shaft for controlling the swash plate of the first hydraulic motor, a second pivot shaft for controlling the swash plate of the second hydraulic motor, a first arm pivoted on a side of the first pivot shaft opposite to the second pivot shaft so as to be linked to the one of the steerable wheels, a second arm provided on the first pivot shaft so as to be linked to the first arm, a third arm provided on the first pivot shaft rotatably integrally with the second arm, and a fourth arm provided on the second pivot shaft, the fourth arm including a first contact portion. When the first arm rotates according to turning of the steerable wheel, the second and third arms rotate from initial positions of the second and third arms, so that the fourth arm, contacting the third arm at the first contact portion, rotates from an initial position of the fourth arm.

    摘要： A transmission arrangement is disclosed which comprises first and second variators (166, 169) each of which comprises an input race (150, 154) and an output race (152, 156). A plurality of rollers (276, 278) is arranged to run upon the input and output races to transfer drive from one to the other. The races are mounted for rotation about a common axis and the inclination of the first variator's rollers is variable independently of the inclination of the second variator's rollers, so that the two rollers are able to provide independently and continuously variable drive ratios. To provide traction between the rollers and races, a biasing device (216, 217) applies an axial force to one of the races, urging the rollers and races into engagement with each other. Each variator is provided with a shunt gear for providing forward, reverse and g eared neutral ratios, and to couple the variator input to the shunt gear a coupling member (160) passes through the outer variator races.

    摘要： The present invention is an improved personal tracked vehicle consisting of a platform pivotally mounted on top of a housing, the platform having a right and left side and a central axis. The platform is pivotally movable between a first position wherein the right side of the platform is below the left side of the platform and a second position wherein the left side of the platform is below the right side of the platform. The platform has a forward portion, a rearward portion and middle portion between the two, the middle portion being arched upwardly. The vehicle further includes a pair of parallel right and left tracks mounted to the housing below the platform, the right track being coupled to a right track transmission and the left track being coupled to a left track transmission, the right and left track transmissions both being coupled to a motor for driving the transmissions. The right and left track transmissions are operatively coupled to the platform such that when the platform is pivoted towards its first position, the left track is driven faster and the right track is driven slower, and when the platform is pivoted towards its second position, the right track is driven faster and the left track is driven slower, the platform being biased towards a central position wherein the left and right drives operate at the same speed. The motor of the vehicle is mounted to the housing below the middle portion of the platform and between the tracks.
