  • Patent number: 10294896
    Abstract: A flap device for an internal combustion engine includes a flow housing which delimits a flow duct, a shaft which rotates, a flap body attached to the shaft in the flow duct, an actuator which rotates the shaft and thereby the flap body in the flow duct, an actuator housing having the actuator arranged therein, a first bearing seat formed on the flow housing, a second bearing seat formed on the actuator housing, a first bearing arranged in the first bearing seat, and a second bearing arranged in the second bearing seat. The shaft projects into the actuator housing. The shaft is mounted at one side via the first bearing and the second bearing.

  • Patent number: 10145310
    Abstract: A flap device for an internal combustion engine includes a flow housing which delimits a flow duct, a shaft which rotates and which is supported on one side thereof, a flap body attached to the shaft in the flow duct, an actuator which rotates the shaft and thereby the flap body, an actuator housing having the actuator arranged therein, a first bearing seat formed on the flow housing, a first bearing arranged in the first bearing seat to radially surround the shaft, a second bearing, a chamber which surround the shaft, and a bore arranged to open into the flow duct from the chamber. The shaft protrudes into the actuator housing. The shaft is supported on the one side via the first bearing and via the second bearing. The chamber from which the bore opens into the flow duct is arranged between the first bearing and the second bearing.

  • Publication number: 20170022944
    Abstract: An exhaust flap device for an internal combustion engine includes a flow housing with a bearing seat, the flow housing delimiting an exhaust duct, a rotating shaft with a thermal conductivity of ?<17 W/mK, a flap body attached to the shaft in the exhaust duct, an electrical actuator with an electric motor and a gearing which has an output gear fixed on the shaft on which the flap body is arranged, an actuator housing having the actuator be arranged therein, and a first bearing with a thermal conductivity of ?>17 W/mK arranged in the bearing seat of the flow housing. The electrical actuator rotates the shaft and thereby the flap body in the exhaust duct. The shaft protrudes into the actuator housing. An inner circumference of the bearing seat corresponds to an outer circumference of the first bearing.

  • Patent number: 9388907
    Abstract: A flap bearing system for a flap shaft in a motor vehicle includes a first radial bearing within which is arranged a flap shaft comprising a flap shaft end. A ratable flap body is arranged on the flap shaft. A flow cross-section of a channel housing is controllable by rotating the flap shaft with the flap body. A first bearing housing surrounds the first radial bearing. A bearing housing cover comprises an opening through which the flap shaft end protrudes. The bearing housing cover closes the first bearing housing. A sleeve radially surrounds a section of the first bearing housing. A circumferential groove is formed at an outer circumference at the section of the first bearing housing surrounded by the sleeve. The flap shaft end protruding from the first bearing housing is arranged geodetically so as to be at a same height or above an opposite flap shaft end.
