Abstract:
Die Erfindung betrifft eine Achsantriebseinheit für ein elektrisch antreibbares Kraftfahrzeug, das wenigstens eine Antriebsachse aufweist. Die Achsantriebseinheit weist wenigstens einen Elektromotor (10, 11) zur Erzeugung eines Antriebsmomentes und wenigstens ein Getriebe (12, 13) zur Übertragung des Antriebsmomentes auf die Antriebsachse auf. Der Elektromotor und das Getriebe bilden eine Baueinheit (15). Die Erfindung hat das Ziel, eine Achsantriebseinheit anzugeben, mit deren Hilfe der Antriebsstrang eines Kraftfahrzeugs möglichst einfach und gewichtssparend aufgebaut werden kann. Hierzu sind eine Leistungselektronik (27) und eine elektromechanische Lenkanlage (17) mit wenigstens einem Elektromotor (25) zur Erzeugung eines Lenkmomentes in die Baueinheit (15) integriert.
Abstract:
The present invention provides a disk brake system comprising a wheel defining a rotational axis, a caliper mounted adjacent the wheel, and a rotor mounted for rotation with the wheel and engageable by the caliper. The rotor includes a mounting slot defined by first and second sidewalls, the first sidewall defining a first axis that substantially intersects the rotational axis, and the second sidewall defining a second axis that is substantially parallel to the first axis. Preferably, the mounting slot defines a center axis that intersects a radial axis of the wheel at an angle of at least 1.5 degrees, preferably at least 2.0 degrees and more preferably about 2.5 to 3.9 degrees. Preferably, the mounting slot has a width and a length that is at least 10% larger, preferably at least 15% larger, and more preferably about 20 % larger than the width.
Abstract:
An emergency braking system for a vehicle, said system being independent of the primary service braking system for the vehicle, wherein the system includes a first cone- shaped copper brake member mounted coaxially on the vehicle drive shaft for limited axial movement but is prevented from rotation by cooperation with a housing fixed to the vehicle chassis, and a second cone-shaped copper brake member fixed coaxially on the drive shaft for rotation with the drive shaft and telescopically received in the first brake member. A cable extends from the first brake member to the cabin of the vehicle so that the driver can move the first brake member axially into contact with the second brake member to slow or stop the vehicle. The first brake member is normally biased out of contact with the second brake member.
Abstract:
A supporting assembly (1) of a wheel with an epicyclic reduction gear system and integrated parking brake, with simplified assembly, the supporting assembly (1) comprising an epicyclic reduction gear unit (2) with at least one reduction stage provided with a driving sun gear (3) associated with a fixed ring gear (5) by interposition of at least one planet gear (6) which is supported by a driven planet gear carrier (7) and is substantially cup-shaped, so as to define a bottom wall (8) associated with at least one supporting pivot (9) of the at least one planet gear (6) and a cylindrical side wall (10) which can be coupled to the hub (104) of a wheel, the ring gear (5) being supported in a fixed manner within the planet gear carrier (7), the assembly (1) comprising, furthermore, a braking assembly (13) provided with a plurality of brake discs (14) which are integral in rotation with the planet gear carrier (7) and a plurality of fixed complementary brake discs (15) interposed between the discs (14), a separate external disc holder (16) which supports the discs (14), being accommodated within the planet gear carrier (7) and being rotationally integral therewith.
