Claims

[Scope of utility model registration request]

A transfer clutch is provided in one of the drive power transmission systems to the front wheels and the rear wheels, and switching between four-wheel drive and two-wheel drive can be performed by controlling the transfer clutch to engage and disengage. Part-time 4
In a wheel drive vehicle, a control circuit that determines vehicle deceleration from a signal from a rotation sensor provided in a drive power transmission system and issues a brake lock signal when the vehicle deceleration exceeds a predetermined value;
A transfer clutch is connected between the brake fluid pressure control device, which controls the braking force of the front and rear four wheels to be loosened and prevents a brake lock, using the above-mentioned brake lock signal. An anti-lock braking device for a part-time four-wheel drive vehicle, characterized in that a connection circuit is provided.
