Claims

[Scope of Claim for Utility Model Registration] The tie rod arms of the left and right front wheels are connected by a tie rod to steer the left and right front wheels, power is transmitted from the rear differential to the left and right rear wheels, and power is transmitted from the front differential to the left and right front wheels. In a four-wheel drive vehicle, left and right clutch brake devices are respectively disposed between the front differential device and the left and right front wheels, the left and right clutch brake devices are housed in a case, and the left and right clutch brake devices are housed in a case, and a shaft on the front differential device side and a slide member capable of connecting and disconnecting the front wheel side shaft and fixing the front differential side shaft,
Furthermore, a lever member connected to the slide member is provided outside the left and right clutch brake device, and the lever member and the tie rod arm are connected via a rod member provided approximately parallel to the tie rod, and the lever member is connected to the tie rod arm via a rod member provided substantially parallel to the tie rod. An adjusting mechanism is interposed between the lever member and the left and right front wheels, and the steering operation of the left and right front wheels is transmitted to the slide member of the left or right clutch brake device via the rod member and the lever member, and the steering operation of the left and right front wheels is transmitted to the slide member of the left or right clutch brake device. A four-wheel drive vehicle characterized in that the front wheels freely rotate and the other front wheel is driven at double speed by braking the shaft on the side of one of the front differentials.
