摘要:
A vehicle according to the present invention includes a first detecting means for detecting an engine speed, a second detecting means for detecting a rotational speed of a rotating member, an engine speed changing means for changing the engine speed, and a control unit. The control unit is electrically connected to the first detecting means, the second detecting means, and the engine speed changing means and controls the engine speed changing means such that when the rotational speed of the rotating member detected by the second detecting means is lower than a set rotational speed previously set in a range from zero to a rotational speed of the rotating member during rotation of the engine in a range between a speed more than an idle rotational speed and a speed less than a predetermined maximum limit rotational speed.

An all-terrain vehicle, which limits a speed of backward movement of the vehicle to a predetermined speed and which assures a necessary power output while limiting the backward speed, without a driver's taking any manual trouble to operate a switch to control an engine of the vehicle, even though a high load is exerted upon the vehicle. The all-terrain vehicle includes a vehicle speed sensor device, a backward movement positional sensor device, and an engine controller for limiting the engine speed of the vehicle when the backward movement positional sensor device detects that the vehicle is running backward and when the vehicle speed sensor device detects that the vehicle speed reaches a predetermined value, thereby limiting the speed of the vehicle running backward.

Disclosed is a four-wheel-drive all terrain vehicle capable of smoothly braking wheels in braking operation of rear wheels and having simplified structures of a drive force disconnecting device and a 2WD/4WD switching device. The drive force disconnecting device is provided in a power transmission path for front-wheel-drive, for engagement/disengagement between a cam shaft and an outer race by means of a torque transmission member such as rollers, to allow a driven-side rotary member such as the outer race to become free when a drive-side rotary member such as the cam shaft is braked during 4WD. The rollers are provided between a plurality of cam faces formed on the cam shaft and a cylindrical friction face formed on the outer race, and they are placed in a torque transmission state (4WD) in which the rollers are pressed between the cam faces and the cylindrical friction face or a torque transmission release state in which the rollers are not pressed between them.

An engine 2, a reduction gear 3, and a clutch 4 detachably coupling a reducing input shaft 25 of the reduction gear 3 to an engine output shaft 24, are housed in and supported to a support and frame work 1. A reducing output shaft 26 of the reduction gear 3 is used for a power takeoff shaft of the drive unit, and an input shaft of a work machine is coupled the power takeoff shaft, so that the work machine is operated. A weight of the support and frame work 1 is made smaller than a total weight of the engine 2, the reduction gear 3 and the clutch 4 so as to decrease a weight of unit. Thus, an over-loading can be overcome easily by using a friction clutch for the clutch 4.

An all terrain vehicle comprising a V-belt continuously variable transmission and a gear-type transmission, being capable of transmitting drive torque from an engine with controlled engine braking but without loss of the torque, thereby giving a rider an improved driving feel. The V-belt continuously variable transmission and the gear-type transmission are placed in this order from upstream in a power transmission path from the engine to wheels. A one-way clutch for transmitting only the drive torque from the engine to the wheel and a torque limiter for transmitting the torque less than a predetermined value are arranged in parallel, between, e.g., a countershaft and forward intermediate gears fitted onto the countershaft.
