Patent number: 8814519Abstract: The present invention relates to a fan, to a method, and to a device for assembling the fan. The fan has an axis of rotation, which is connected to a dog, wherein the dog is connected to a fan wheel, wherein the dog, in a first number of contact surfaces, is in contact with additional contact surfaces of the fan wheel, wherein the dog and/or the fan wheel have more than the first number of contact surfaces and/or additional contact surfaces, wherein at least two contact surfaces have different height positions with respect to a central axis of the dog and/or the fan wheel.Type: GrantFiled: September 3, 2009Date of Patent: August 26, 2014Assignee: Robert Bosch GmbHInventor: Klaus Linnenbrock

Patent number: 8720064Abstract: The invention relates to a cooling fan for a cooling system of the internal combustion engine of a motor vehicle, the cooling fan comprising at least one frame (10) for retaining a fan motor and a fan motor (24) for driving a fan wheel (26). The invention is characterized in that at least one motor casing component of the fan motor (24) is injection-molded into the frame material and/or is coated by said material by injection molding when the frame (10) is formed. The invention also relates to a method for producing said cooling fan. The method according to the invention is characterized in that at least one motor casing of the fan motor (24) is injection-molded into the frame material and/or is coated by said material by injection molding when the frame (10) is formed.Type: GrantFiled: September 6, 2007Date of Patent: May 13, 2014Assignee: Robert Bosch GmbHInventors: Jens Ulrich, Richard Vogt, Klaus Linnenbrock, Thomas Helming

Patent number: 8616859Abstract: The invention relates to a fan, particularly for cooling an internal combustion engine of a vehicle, having an attachment unit, an electric drive motor, and a fan wheel rotating about the fan axis, wherein the attachment unit has a frame, from which bars protrude that cross through an air opening, said bars carrying an attachment element serving to attach the drive motor. The invention proposes that each of the bars (6) have a cross-sectional contour, wherein at least one cross bar (18) extending laterally in the direction of the fan axis (9) is configured between end regions (14, 15) of the bar (6) extending in the direction of the fan axis (9), defining a bar width (b).Type: GrantFiled: September 23, 2008Date of Patent: December 31, 2013Assignee: Robert Bosch GmbHInventors: Rolf Kroeg, Klaus Weickenmeier, Klaus Linnenbrock, Thomas Helming

Publication number: 20130187519Abstract: A moving element is connected to a rotor of an electric motor in a manner locked in terms of torque and, together with the rotor, forms a rotation element. An angle of inclination of the moving element in relation to the rotor is defined by bearing elements which are arranged on a circumference about the axis of rotation of the rotor, wherein the bearing elements each define axial distances between the rotor and the moving element. Each bearing element is formed by a first and a second axial section, and the moving element can be brought into different rotational positions in relation to the rotor so as to produce different pairings of the first and second sections, said pairings corresponding to different angles of inclination.Type: ApplicationFiled: May 10, 2011Publication date: July 25, 2013Applicant: ROBERT BOSCH GMBHInventors: Klaus Linnenbrock, Julien Casagrande, Tobias Schneider

Publication number: 20120063887Abstract: The utilization of double fans for engine cooling of motor vehicles is known. Said fans generate a flow of air which then serves to cool a heat exchanger, in particular a coolant radiator for motor vehicles. The double fan is herein characterized by an optimal use of the surface of the coolant radiator that is to be cooled, so as to be able to achieve a cooling performance as high as possible. The assembly of the double fan has up to now been such that a separate electric motor is provided for each blower. The double fan (1) for a heat exchanger (2), in particular a coolant radiator of a motor vehicle, has a first blower (4) and a second blower (5). According to the invention, the first driven blower (4) drives the second blower (5) by way of a transmission element (10) provided on the outer surface (11) of the first blower and an outer surface (12) of the second blower (5). The double fan is provided for a heat exchanger, in particular a coolant radiator of a motor vehicle.Type: ApplicationFiled: February 2, 2010Publication date: March 15, 2012Applicant: ROBERT BOSCH GMBHInventors: Jochen Goehre, Klaus Linnenbrock, Joerg Eigenmann, Thomas Helming, Asli Arslan-Huerst
