A transmission device or an electric axle which has improved operational characteristics compared to known solutions. Said aim is achieved by providing a transmission device (1) including an electric motor (3) provided with a rotor (6), a planetary gear (4) provided with at least one sun gear (9), and a shaft arrangement (7,8), the rotor (6) being coupled in a rotationally fixed manner to the sun gear (9) by the shaft arrangement (7, 8). The shaft arrangement (7,8) includes at least one compensation interface (21) which is designed such that it is possible to change the distance and/or tilting between the motor (6) and sun wheel (9).
摘要:
A displaceable system including at least one set of at least two wheels arranged in pairs for movement in a plane, said set being disposed on at least one wheel axle parallel to the plane. A single electric drive motor, a differential having variable torque distribution, and an electric servomotor are provided on the wheel axle for both wheels of a set. The electrical servomotor acts on the differential such that the torque generated by the single electric drive motor is distributed within the wheel axle individually to the wheels.
摘要:
A freewheel clutch that has sprags, which are located between an inner locking track and an outer locking track and two sliding discs which each feature one inner axis adjacent to the inner locking track, one outer axis adjacent to the outer locking track as well as one middle section which connects the axes, and has an axial inwardly directed bending. The bending extends from the outer axis to the inner axis and preferably features a maximum embossing depth which is lower than the wall thickness of the middle section.
摘要:
A drive unit for motor vehicles having which has at least one electrical motor and at least one transmission assembly. The electrical motor and the transmission assembly are operatively connected to one another by at least one shaft and the shaft is rotatably mounted by at least one first rolling bearing which sits in a rotary union for the shaft in the transmission assembly.
摘要:
A rolling bearing that has at least one first row of roiling elements and one second row of rolling elements as well as a common bearing ring for both rows.
摘要:
A coupling having at least two concentric rings, each having a circumferential surface and a recess, and at least two roller elements. The roller elements are each disposed in a channel formed by the circumferential surface of one of the rings and the recess of another of the rings. In some example embodiments of the invention, the coupling includes a coupling member with a bearing surface, at least one of the rings includes a split and the split ring is urged against the bearing surface when there is relative rotation between the rings. The coupling member is, for example, a shaft or a gear.
摘要:
A sprag for a sprag-type freewheel clutch having a profile comprised of multiple profile sections, the sprag having at least the profile sections of an inner engagement curve, an outer engagement curve and a first and a second lateral curve, wherein the outer and inner engagement curves each form a component of a logarithmic spiral.
摘要:
A preload unit module, wherein which has at least one ramp disk and a cage, which carries a plurality of rolling bodies that are held axially against one another in a positively locking fashion. The cage is rotationally pivotable relative to the at least one ramp disk.
摘要:
Example aspects of the present invention broadly comprise at least two concentric rings with complementary ramped surfaces, at least one of the rings being rotatable relative to another one of the rings so that contact is made at the ramped surfaces. The complementary ramped surfaces form respective circumferences of the rings. At least one of the ramped surfaces may have a sinusoidal profile, or a profile forming at least one of a straight line, concave, or convex. In some example embodiments of the invention, a first one of the rings is a coupling member and a second one of the rings is a tubular slipper with a friction surface radially opposite of the ramped surface. The tubular slipper is arranged to radially expand or contract upon contacting the coupling member.
