Top door for electric refuse vehicle
A refuse vehicle includes a chassis, a body assembly coupled to the chassis, an electric energy system, and a door system. The body assembly defines a refuse compartment. The body assembly has a cover that at least partially encloses the refuse compartment such that an opening is defined in the body assembly to provide access to the refuse compartment. The door system is coupled to the cover. The door system includes a panel and an electric actuator powered by the electric energy system. The electric actuator is configured to selectively reposition the panel between a first position where the panel extends across the opening and a second position where the panel does not extend across the opening.
1 . A refuse vehicle comprising:
a chassis;
a body assembly coupled to the chassis, the body assembly defining a refuse compartment and an opening in a roof to provide access to the refuse compartment; and
a door system comprising:
a door disposed on the roof of the body assembly; and
an electric actuator configured to linearly extend or retract to translate the door between a closed position where the door limits access to the refuse compartment through the opening and an open position where the refuse compartment is accessible through the opening, wherein the electric actuator is centered along a longitudinal centerline of the door and is configured to provide a force to the door along the longitudinal centerline of the door to move the door between the closed position and the open position by providing a force along the longitudinal centerline of the door without rotating the door;
wherein the electric actuator extends over the door and is coupled with a rear actuator interface on the body assembly, wherein the rear actuator interface is disposed at a rear end of the body assembly.
2 . The refuse vehicle of claim 1 , wherein the electric actuator is a ball screw actuator driven by an electric motor.
3 . The refuse vehicle of claim 2 , wherein the ball screw actuator is positioned along the longitudinal centerline of the door.
4 . The refuse vehicle of claim 2 , wherein the ball screw actuator is a first ball screw actuator, the door system further including a second ball screw actuator, the first and second ball screw actuators configured to selectively reposition the door between the closed position where the door extends across the opening and the open position where the door does not extend across the opening.
5 . The refuse vehicle of claim 4 , wherein the first ball screw actuator and the second ball screw actuator are located along opposed sides of the door.
6 . The refuse vehicle of claim 5 , wherein the first ball screw actuator and the second ball screw actuator operate in synchronization.
7 . The refuse vehicle of claim 1 , wherein the electric actuator is coupled with a portion of the body assembly at a first end and is coupled with a portion of the door at a second end.
8 . A refuse vehicle comprising:
a body assembly coupled to a chassis, the body assembly defining an inner volume and an opening in a roof to provide access to the inner volume; and
a door system comprising:
a door disposed on the roof of the body assembly; and
an electric actuator configured to linearly extend or retract to selectively translate the door in a longitudinal direction between a closed position where the door limits access to the inner volume through the opening and an open position where the inner volume is accessible through the opening, wherein the electric actuator is centered along a longitudinal centerline of the door and is configured to provide a force to the door in a direction that is parallel with the longitudinal direction of the door to selectively reposition the door between the closed position and the open position without causing the door to pivot, wherein the longitudinal direction of the door extends in a direction from a front of the refuse vehicle to a rear of the refuse vehicle;
wherein the electric actuator is coupled with a rear actuator interface on the body assembly, wherein the rear actuator interface is disposed at a rear end of the body assembly.
9 . The refuse vehicle of claim 8 , wherein the electric actuator is a ball screw actuator driven by an electric motor.
10 . The refuse vehicle of claim 9 , wherein the ball screw actuator is positioned along the longitudinal direction of the door.
11 . The refuse vehicle of claim 9 , wherein the ball screw actuator comprises a first ball screw actuator and a second ball screw actuator, the first and second ball screw actuators configured to selectively reposition the door between the closed position where the door extends across the opening and the open position where the door does not extend across the opening.
12 . The refuse vehicle of claim 11 , wherein the first ball screw actuator and the second ball screw actuator are located along opposed sides of the door.
13 . The refuse vehicle of claim 12 , wherein the first ball screw actuator and the second ball screw actuator operate in synchronization.
14 . The refuse vehicle of claim 8 , wherein the electric actuator is coupled with a portion of the body assembly at a first end and is coupled with a portion of the door at a second end.
