Claims

[Claims for Utility Model Registration] 1. Transmits power from a power source to the main driving wheels, and also transmits it to the driven wheels via the propulsion shaft, and connects the power transmission path from the power source to the driven wheels. , a displacement amount that detects the amount of vertical displacement of the vehicle body on each side of the vehicle in the left and right direction in a front and rear wheel drive vehicle equipped with a transmission that has a transmission mechanism that makes the average rotation speed of the main drive wheel and the slave drive wheels different. 1. A front and rear wheel drive system for a vehicle, comprising: a detection device; and a control device that controls the operation of the transmission based on the difference between left and right vertical displacements determined by the detection device. 2. The front and rear wheel drive device for a vehicle according to claim 1, wherein the vertical displacement amount is detected from the displacement amount of a left and right suspension of at least one of the main drive wheel side and the slave drive wheel side. 3 The power from the power source is transmitted to the main drive wheels and also to the sub drive wheels via the propulsion shaft, and the power transmission path from the power source to the sub drive wheels includes the main drive wheels and the sub drive wheels. A rotation speed detection device for detecting the rotation speed of at least one of the left and right wheels on the main drive wheel side and the slave drive wheel side in a front and rear wheel drive vehicle equipped with a transmission having a transmission mechanism that makes each average rotation speed different. A front and rear wheel drive system for a vehicle, comprising: a control device for controlling the operation of the transmission based on the difference in rotational speed between the left and right wheels determined by the detection device.
