Abstract
A braking system for a portal lift assembly includes a shaft operably connected to a vehicle power source and effective to directly or indirectly rotate a wheel of the vehicle upon rotation of the shaft about its axis, a piston positioned along the shaft and effective for applying an axial force along the axis of the shaft, a fluid channel fillable with a non-compressible fluid and effective to apply a hydraulic force to the piston when pressure is applied to fluid in the line, a pressure plate positioned along the shaft and effective for applying an axial force along the axis of the shaft in response to the application of an axial force by the piston. A clutch pack is positioned between the pressure plate and the piston, and includes two sets of clutch plates radially surrounding the shaft. The first set of clutch plates is connected to the shaft in a manner effective to cause those clutch plates to rotate about the axis of the shaft when the shaft rotates. The second set of clutch plates is prevented from rotating about the axis of the shaft. Members of the first set of clutch plates are interspersed between members of the second set of clutch plates, so that when the clutch pack is sufficiently compressed by axial forces applied by the piston and the pressure plate, the first set of clutch plates is forced against the second set of clutch plates so that friction forces between members of the first set of clutch plates and members of the second set of clutch plates slow and may subsequently stop the rotation of the shaft.
