Apparatus and methods for cooling controller assemblies for electric utility vehicles are disclosed. Auxiliary implements powered by electric motors onboard a utility vehicle create airflow that is captured and directed to provide increased ambient airflow across heat sinks used to dissipate heat from heat generating components. Airflow across heated surfaces is further created by vehicle movement and vacuum pressure. Fins and other heat dissipating architecture are employed. Features of the cooling systems enable increased controller assembly functionality and/or decreased controller assembly package size.

Systems and methods for cooling a controller assembly

A drive apparatus having an actuator assembly mounted on a control device is disclosed. The drive apparatus comprises an input, a variable drive system, a control device, and an actuator assembly. The drive apparatus is mounted on a vehicle that comprises an operating system. A prime mover drives the input, which subsequently drives one or more axle shafts. The variable drive system is capable of operation in forward and reverse directions. The control device determines the direction of operation and speed of the variable drive system. The actuator assembly is mounted to a component of the control device. The actuator assembly determines the state of operation of the output device with respect to the forward or reverse operation of the variable drive system.

Actuator assembly

A hydraulic drive apparatus having an actuator assembly mounted on a control device is disclosed. The hydraulic drive apparatus comprises an input, a hydraulic pump, a control device, and an actuator assembly. The hydraulic drive apparatus is mounted on a vehicle that comprises an operating system. A prime mover drives the input, which subsequently drives one or more axle shafts. The transmission is capable of operation in forward and reverse directions. The control device determines the direction of operation and speed of the transmission. The actuator assembly is mounted to a component of the control device. The actuator assembly determines the state of operation of the output device with respect to the forward or reverse operation of the transmission.

Actuator assembly for hydraulic drive apparatus

A control assembly for use with hydraulic apparatus having a housing, a trunnion extending from the housing, a return arm and a control arm mounted on the trunnion. The control assembly is attached to the trunnion arm and includes a pair of scissor return arms biased to place the hydraulic apparatus in a neutral condition, a pair of bushings and a spacer pressed into the bushings to form the assembly.
