Abstract
Disclosed is a superimposition steering unit in which a steering angle set by the driver can have an additional angle superimposed thereon. The superimposition is caused by individually operable structural components.
Claims15
A superimposition steering unit comprising:
- a steering angle set by a driver can be superimposed by an additional angle;
- one or more individually operable structural components, wherein the one or more individually operable structural components controls a superimposition function of the superimposition steering;
- a superimposition gear, which has at least one secondary gear module (16) and one primary gear module (17) as two individually operable structural components;
- wherein the secondary gear module (16) has a drive motor (5), a frontal or belt drive (23), and a primary gear drive unit (24);
- and
- wherein the primary gear drive unit (24) has a main drive wheel (25), a free-run spring (26), a clamping body spring (27), a clamping body (28), a clamping and support ring (29), a coupling of the primary gear (30), a secondary gear support (31), and clamping inclines (32).

A superimposition steering unit comprising:
- a steering angle set by a driver that can be superimposed by an additional angle;
- one or more individually operable structural components, wherein the one or more individually operable structural components controls a superimposition function of the superimposition steering;
- a superimposition gear, which has at least one secondary gear module (16) and one primary gear module (17) as two individually operable structural components;
- wherein the secondary gear module (16) has a drive motor (5), a frontal- or belt drive (23), and a primary gear drive unit (24);
- wherein the primary gear drive unit (24) has a momentum-controlled free-run unit acting on both sides, which free-run unit has means to ensure that, within a nominal range (25) of steering momentum, a required superimposition angle is conveyed, by means of the secondary gear module (16) and the primary gear module (17), onto a steering gear (14) of the superimposition steering and, in the event of an overload, if the steering momentum (35) applied leaves the nominal range, a reversal of the primary gear drive unit (24) is thereby impeded;
- wherein the primary gear module (17) has a planetary gear unit (18) and a locking unit (21);
- and
- wherein an individually operable structural component is provided as a locking unit (21) in a primary gear casing and the primary gear casing can lock the superimposition gear (1) in the event of an error.
