Publication number: 20230070927Abstract: A linkage arrangement for a working machine, the linkage arrangement being connectable to a work implement. The linkage arrangement includes a single boom lifting arm extending along a longitudinal centre axis and being configured to lift the work implement, and a tilting arrangement having two hydraulically driven arms arranged in parallel and being configured to tilt the work implement relative the single boom lifting arm. Each one of the two hydraulically driven arms is hydraulically driven by a separate hydraulic tilting cylinder.Type: ApplicationFiled: August 29, 2022Publication date: March 9, 2023Inventor: Joakim Unnebäck

Patent number: 11318861Abstract: A coolant system for an electric vehicle having first and second heat generating components includes a fluid circuit that circulates a coolant therethrough and a coolant assembly. The coolant assembly decreases the temperature of a portion of the coolant to a first temperature and supplies the portion of coolant to the first heat generating component via a first supply branch of the fluid circuit, and decreases the temperature of a remaining portion of the coolant to a second temperature and supplies the remaining portion of coolant to the second heat generating component via a second supply branch of the fluid circuit. The system includes a first pump unit, arranged downstream of the coolant assembly in the first supply branch, that directs the portion of coolant to the first heat generating component, and a second pump unit that directs the remaining portion of coolant to the second heat generating component.Type: GrantFiled: December 6, 2017Date of Patent: May 3, 2022Assignee: Volvo Construction Equipment ABInventors: Joakim Unnebäck, Erik Carldén

Publication number: 20190217765Abstract: A working machine includes a receptacle portion for accommodating load. The working machine is adapted to have a load receiving condition in which the receptacle portion includes an open load receiving area outwardly delimited by a load receiving area circumference. The working machine extends in at least a vertical direction and the working machine includes a circumference projection being a projection of the load receiving area circumference in the vertical direction onto a ground on which the working machine is located. The working machine is such that it, in the load receiving condition, can assume a position relative to a second working machine of the same type in which position the circumference projections of the two working machines at least partially overlap.Type: ApplicationFiled: August 25, 2016Publication date: July 18, 2019Inventor: Joakim UNNEBÄCK
