摘要:
A vehicle comprises a transaxle, a battery and a load carrying bed. The transaxle includes a casing incorporating a drive train and supporting an axle and includes an electric motor mounted on the casing to drive the axle via the drive train. The battery is provided for supplying electric power to the electric motor. The transaxle and the battery are disposed below the load carrying bed so as to overlap the load carrying bed when viewed in plan.

A work vehicle according to the present invention includes an engine installed in a traveling machine body supported by traveling units, and a transmission case incorporating a hydraulic continuously variable transmission. The transmission case incorporates a forward/backward traveling switching mechanism. The work vehicle includes forward traveling valves for forward traveling hydraulic clutches, a backward traveling valve for a backward traveling hydraulic clutch, and a master valve configured to control hydraulic oil supplying to the forward traveling valves and the backward traveling valve. A part of a hydraulic circuit is formed on a front lid member of the transmission case. The forward traveling valves, the backward traveling valve, and the master valve are attached on a front surface side of the front lid member.

A drive package includes a remote located CVT and a motor where the CVT is positioned rearward (or forward) of the motor. An auxiliary drive mechanism couples a drive shaft of the CVT to a crankshaft of the motor. The auxiliary drive mechanism is a belt or chain. The drive shaft is substantially parallel to, and longitudinally offset from, the crankshaft. Thus, the width of the drive package is reduced as compared to ATVs having a CVT located adjacent the motor. A method of making an ATV with the drive package is provided.

A drive shaft assembly for a vehicle includes a first tubular member and a second tubular member that is received by the first tubular member defining a coaxial relationship. The first tubular member defines a plurality of protuberances with each of the protuberances defining a side wall and the second tubular member defines a plurality of apertures with each of the apertures defined by a flange circumscribing the aperture and extending radially inwardly of second tubular member. Each aperture receives a protuberance so that the protuberance abuts the sidewalls of the aperture affixing the first tubular member to said second tubular member in a substantially fixed circumferential orientation.

A dual-independent powertrain for a vehicle includes a transmission enclosure that houses a first transmission and a second transmission that are mechanically decoupled from each other. The enclosure includes a central frame, a first enclosure cover that interfaces with the central frame to collectively define a first transmission region on a first side of the central frame, and a second enclosure cover that interfaces with the central frame to collectively define a second transmission region on a second side of the central frame. The first transmission is housed within the first transmission region, and the second transmission is house within the second transmission region. Each transmission includes a motor-interfacing shaft that interfaces with a respective electric motor, a drive-interfacing shaft that interfaces with a respective drive wheel of a vehicle, and a multi-stage gear train mechanically coupling the motor-interfacing shaft and the drive-interfacing shaft.

A torque distribution system for a model racing car includes a front pair of wheels, a front axle, a front differential coupled to the front axle, a rear pair of wheels, a rear axle, a rear differential coupled to the rear axle, a center differential a front driveline coupling the center differential and the front differential, a rear driveline coupling the center differential and the rear differential, and a motor coupled to the center differential. The motor and center differential are mounted in the car at an angular orientation with respect to the centerline. The front and rear drivelines are angularly oriented at different angular orientations. The differing angular orientations of the front and rear drivelines are characterized by corresponding differing amounts of friction, resistance or efficiency of the front and rear drivelines to transmission of torque.

One exemplary illustration of a torque transfer device for a vehicle may include a housing and a variable angle constant velocity joint integrated with the housing. The joint may be connected between a drive mechanism and an output shaft for transmitting torque from the drive mechanism to the output shaft.
摘要:
A method for assembling a propshaft assembly. The method can include: providing a tubular member, the tubular member having an annular wall with an inside circumferential surface; twisting a damper; installing the twisted damper in the tubular member; untwisting the damper in the tubular member such that the damper engages the inside circumferential surface of the annular wall. A machine for assembling a propshaft assembly is also provided.
摘要:
A damped propshaft assembly with a hollow shaft and a tuned damper, which is received in the hollow shaft and includes a liner and a damping member. The liner's mass and stiffness are tuned to attenuate one or more of a bending mode vibration and a torsion mode vibration that occurs at a first predetermined frequency. The liner is not configured to substantially damp shell mode vibration that occurs at a frequency that is not equal to the first predetermined frequency. The damping member is coupled to the liner and is configured to primarily attenuate shell mode vibration in the hollow shaft at one or more desired frequencies. The tuned damper attenuates the at least one of the bending moment vibration and the torsion mode vibration at the first predetermined frequency and also attenuates shell mode vibration. A method for forming a damped propshaft assembly is also provided.
摘要:
A hybrid vehicle which is driven using the power of an engine and the power of a drive motor which is driven by an electric power supplied from a battery module, the vehicle including: a propeller shaft which is disposed below a floor panel in a vertical direction of the vehicle extending in a fore-and-aft direction of the vehicle, and is configured to transmit the power of the engine and the power of the drive motor to a rear wheel; and a battery pack having the battery module, the battery pack being disposed below the floor panel so as to cover the propeller shaft. The battery pack has a recess formed in a fore-and-aft direction of the vehicle, and the propeller shaft is housed in an air guide duet defined by the floor panel and the recess of the battery pack.
