Electrical vehicle parking brake device

摘要

An electrical vehicle parking brake device capable of reducing the size towards a cable shaft and improving the degree of freedom of mounting in a vehicle is provided for the electrical vehicle parking brake device of controlling the braking force to a wheel due to the driving power of a motor which is transmitted by way of a cable at the time of parking the vehicle. At the time of parking the vehicle, in the electrical vehicle parking brake device of controlling the braking force to the wheel due to the driving power of a motor which is transmitted by way of a gear mechanism and a cable at the time of parking the vehicle, an end gear series of the gear mechanism is structured of an external gear and an internal gear, the external gear uses a K-H-V type planetary gear mechanism in which external gear turns to the extent of a difference between the numbers of teeth between the external gear and the internal gear by making one revolution in an inner circumference side of the internal gear and also the cable is wound up in a circular shape in the external gear.
