Patent number: 11850928Abstract: An electric drive axle for a vehicle includes at least one first electric vehicle drive system (1) for driving at least one vehicle wheel (11, 12) and at least one connection interface (8) for at least one power take-off (PTO). The vehicle drive system (1, 13) is coupled at least to one first double shift element (6) such that, at least in a first engagement position of the first double shift element (6), the vehicle drive system (1, 13) is drivingly coupled to at least one vehicle wheel (11, 12) and, in a second engagement position of the first double shift element (6), the vehicle drive system (1, 13) is decoupled from the at least one vehicle wheel (11, 12) and is drivingly coupled to the connection interface (8) for the power take-off (PTO). A vehicle with an electric drive axle is also provided.Type: GrantFiled: September 13, 2019Date of Patent: December 26, 2023Assignees: ZF FRIEDRICHSHAFEN AG, ZF DRIVETECH (SUZHOU) CO. LTD.Inventors: Frank Seemann, Paul Lenz, Andreas Grossl, Werner Hechberger, Kai Borntraeger, Maik Woerl, Marco Di Sarno, Cong Ren

Patent number: 11807091Abstract: An axle drive (1) for a motor vehicle axle includes at least a first drive unit (2), a second drive unit (2), and an output axle (6). The first and second drive units (2) are arranged such that an overall center of gravity (7) of the axle drive (1) is situated proximate to a center of the output axle (6) and/or an axis of rotation of a vehicle wheel of the motor vehicle driven by the axle drive (1).Type: GrantFiled: September 13, 2019Date of Patent: November 7, 2023Assignees: ZF FRIEDRICHSHAFEN AG, ZF DRIVETECH (SUZHOU) CO. LTD.Inventors: Frank Seemann, Paul Lenz, Andreas Grossi, Werner Hechberger, Kai Borntraeger, Maik Woerl, Marco Di Sarno, Cong Ren

Patent number: 11780328Abstract: A drive device for an electrically driven axle of a motor vehicle may include at least one electric machine, a shiftable transmission connected downstream from the at least one electric machine, and a differential coupled to the transmission for distributing drive torque to the axle. The transmission has first and second planetary gear sets connected in series. The at least one electric machine engages with an external toothing of a ring gear of the first planetary gear set. A carrier of the first planetary gear set is rotationally fixed to a sun gear of the second planetary gear set. A sun gear of the first planetary gear set is detachably couplable to a housing. A ring gear of the second planetary gear set is coupled to the housing. A carrier of the second planetary gear set is an output of the transmission. The first planetary gear set is interlockable.Type: GrantFiled: September 17, 2019Date of Patent: October 10, 2023Assignees: ZF FRIEDRICHSHAFEN AG, ZF DRIVETECH (SUZHOU) CO.

Patent number: 11268567Abstract: A sealing element for a ball joint has a sealing area on the housing side and a sealing area a distance away therefrom in an axial direction of the sealing element on the stud side. Arranged between the housing-side sealing area and the stud-side sealing area is an outlet opening which extends through the sealing element to allow the passage of spent lubricant. The outlet opening extends in the axial direction of the sealing element, passing all the way through the sealing element in the axial direction. Further, the sealing element is incorporated in a ball joint which is incorporated in a two-point control arm.Type: GrantFiled: December 11, 2018Date of Patent: March 8, 2022Assignees: ZF Friedrichshafen AG, ZF Gainsville, LLCInventors: Dirk Sokolihs, Uwe Petersen, Joe Vierthaler, Marco Di Sarno, Holger Hardt

Patent number: 11261906Abstract: A ball joint for a chassis component in the form of a two-point linkage. The ball joint includes a housing and a ball stud fitted and able to be deflected in the housing, as well as a sealing element arranged between the housing and the ball stud, which surrounds the ball stud all round. Deflection movement of the ball stud, relative to the housing, is restricted at least in some areas by the sealing element. The sealing element is attached to the housing by an interlocked connection. The sealing element of the ball joint is attached to the housing by a snap-on connection. A two-point linkage having such a ball joint, and the two-point linkage is a steering rod or a track rod.Type: GrantFiled: May 21, 2018Date of Patent: March 1, 2022Assignee: ZF Friedrichshafen AGInventors: Dirk Sokolihs, Uwe Petersen, Holger Hardt, Marco Di Sarno

Publication number: 20220032893Abstract: An electrically driven axle with electrical drive units (4) arranged symmetrically around the axle body (1). The drive units having an electric machine and a transmission, and at least one spring-loaded brake (3) as a parking brake. The spring-loaded brakes (3) are arranged radially, thus enabling the spring-loaded brake (3) to be released by removing a release spindle (7) from brake cylinders of the spring-loaded brakes (3).Type: ApplicationFiled: September 13, 2019Publication date: February 3, 2022Inventors: Frank SEEMANN, Paul LENZ, Andreas GROSSL, Werner HECHBERGER, Kai BORNTRAEGER, Maik WOERL, Marco DI SARNO, Cong REN
