SYSTEMS FOR A HYDRAULIC CIRCUIT
Systems are provided for a mobile asset. In one example, a gear pump coupled to an electric motor and a tank, the gear pump comprising an end cover with a hydraulic integrated circuit (HIC) arranged therein. A shaft extending from the electric motor to the gear pump is housed via only an electric motor housing and the end cover.
1 . A system, comprising:
a gear pump coupled to an electric motor and a tank, the gear pump comprising an end cover with a hydraulic integrated circuit (HIC) arranged therein.
2 . The system of claim 1 , wherein an inlet line and a return line extend directly between the tank and the gear pump.
3 . The system of claim 2 , wherein the return line comprises a filter.
4 . The system of claim 2 , wherein the HIC controls one or more of steering, lifting, and lowering.
5 . The system of claim 1 , wherein the gear pump is arranged in an off-highway vehicle.
6 . The system of claim 1 , wherein a shaft extends from the electric motor to the gear pump, and wherein the shaft is free of a shaft housing.
7 . The system of claim 1 , wherein the electric motor is mounted directly to a pump cover of the pump.
8 . The system of claim 1 , wherein the fuel tank is mounted directly to a pump cover of the pump.
9 . An off-highway vehicle, comprising:
a gear pump coupled to an electric motor, the gear pump comprising an end cover with a hydraulic integrated circuit (HIC) arranged therein; and
a tank directly coupled to the gear pump.
10 . The off-highway vehicle of claim 9 , wherein the gear pump comprises an inlet port coupled to an inlet line arranged in an interior of the tank.
11 . The off-highway vehicle of claim 10 , wherein the gear pump comprises an outlet port coupled to a return line extending from the outlet port to a filter arranged in the interior of the tank.
12 . The off-highway vehicle of claim 9 , wherein electric motor is directly mounted to the gear pump.
13 . The off-highway vehicle of claim 9 , wherein the gear pump is outside an interior of the tank.
14 . The off-highway vehicle of claim 9 , wherein the off-highway vehicle is a scissor lift or a fork lift.
15 . The off-highway vehicle of claim 9 , wherein a plurality of lines fluidly coupling the tank to the gear pump are housed by a pump cover of the gear pump.
16 . An off-highway vehicle, comprising:
a pump comprising a pump cover comprising a plurality of mounting points; and
an electric motor directly mounted to the pump cover, wherein a shaft extending from the electric motor to the pump is housed via only an electric motor housing and the pump cover.
17 . The off-highway vehicle of claim 16 , wherein a tank is directly mounted to the pump cover, and wherein lines fluidly coupling the tank to the pump are housing via only a tank housing and the pump cover.
18 . The off-highway vehicle of claim 16 , wherein the pump further comprises an end cover comprising a hydraulic integrated circuit (HIC) integrally arranged within the end cover.
19 . The off-highway vehicle of claim 18 , wherein the HIC controls steering, lifting, and lowering of a component of the off-highway vehicle.
20 . The off-highway vehicle of claim 16 , wherein a plurality of valves is arranged within the pump.
