Parking brake for a skid steer loader vehicle

Claim 1

In a skid steer vehicle having first and second separate drive means operable to independently drive first and second sets of drive wheels mounted on opposite sides of the vehicle, including a pair of hydrostatic motors axially aligned for driving each set of wheels independently, each motor having an output shaft extending therefrom for engagement with its respective drive means, a brake mechanism comprising a pair of rotatable discs, each disc mounted on the respective output shaft of an associated hydrostatic motor for integral rotation therewith, a mounting bracket assembly mounted adjacent to the drive means of the vehicle and overlying the rotatable discs, engageable portions disposed in the mounting bracket assembly and movable independently thereof, and actuating means disposed adjacent to the engageable portions, whereby movement of the actuating means in a locking direction forces the engageable portions into contact with the rotatable discs of the brake mechanism, stopping the rotation of the discs and locking the drive means of the vehicle in fixed relation, said mounting bracket assembly having separable portions through which the discs freely rotate when the drive means is engaged and the portions engaging the discs comprise brake members capable of having a compressive force applied thereto, said brake members being carried on the mounting bracket and disposed on opposite sides of the rotatable discs and interposed therebetween for engagement therewith.
