Abstract:
1. A drive apparatus for use on a vehicle having a prime mover driving an input pulley connected to a drive belt, the drive apparatus comprising: a first transmission comprising a first housing, a first input shaft, a first drive pulley disposed on the first input shaft and driven by the drive belt, a first brake, and a first brake arm located external to the first housing, whereby actuation of the first brake arm engages the first brake; a second transmission comprising a second housing, a second input shaft, a second drive pulley disposed on the second input shaft and driven by the drive belt, a second brake, and a second brake arm located external to the second housing, whereby actuation of the second brake arm engages the second brake; a first emergency brake actuator disposed external to the first transmission and engaged to the first brake arm; a second emergency brake actuator disposed external to the second transmission and engaged to the second brake arm; a release member capable of actuating both the first and second emergency brake actuators; and a movable assembly engaged to the drive belt and moveable between a first position and a second position, whereby tension from the drive belt retains the movable assembly in the first position, the movable assembly further comprising a contact member and a bias member engaged to the movable assembly to bias the movable assembly towards the second position whereby, when tension from the drive belt is removed from the movable assembly, the bias member forces the contact member into engagement with the release member to engage the first and second emergency brake actuators.
