Definitions
- the invention relates to a steering with an adjusting device, which has a spindle with a spindle thread and a spindle nut with a female thread, which is in engagement with the spindle thread.
- the invention further relates to a use of the adjusting device.
- JP 2002079947 A2 uses a so-called vernier motor, which has a high torque and a small installation space due to its special design and control of a multiplicity of coils.
- This spindle drive is arranged at the end of a steering gear, whereby the steering has a large axial extent and thus has a high space requirement.
- the invention pursues the goal of further improving a steering system with an adjusting device.
- the steering in particular rear-axle steering, to be formed with an adjusting device which has a spindle drive with a spindle and a spindle nut rotatably mounted in the housing of the steering.
- the invention is characterized by an electric motor which is designed as a Vernier motor and is coupled as a drive with the spindle drive.
- the spindle nut is rotated and cooperates with the external thread of the spindle in such a way that ultimately the axial movement of the spindle is generated - depending on the direction of rotation, the spindle is displaced axially in one direction or the other.
- the electric motor is preferably designed as a brushless vernier electric motor. These types of electric motors form a highly efficient electric motor that has improved volume efficiency compared to conventional electric motors.
- a vernier motor can generate a higher torque with less volume than a conventional electric motor with a correspondingly larger volume.
- an electric motor can be downsized while having higher power.
- the same size as a conventional electric motor can be maintained and the power is comparatively higher. It can thus be shown for the adjusting device or the steering, in particular rear axle steering, a total of very compact steering, so that the space required for the steering, especially rear axle steering can be reduced enormously.
- the vernier motor is not only smaller than a comparable electric motor. It is also lighter and more power efficient than a comparable conventional electric motor with sufficient torque to drive the spindle drive of a steering, especially in a rear axle steering with axially displaceable with respect to a housing spindle.
- the design namely, the weight of the magnets can be reduced. As a result, less rare earths have to be used to make the magnets, which makes the Vernier motor much cheaper than a comparable electric motor with the same power.
- the Vernier motor is arranged with its longitudinal axis parallel to the longitudinal axis of the spindle and the spindle nut.
- the spindle nut by the vernier motor by means of a transmission, preferably by means of a traction drive with drive belt or by means of a gear train, in particular planetary gear, driven.
- a transmission preferably by means of a traction drive with drive belt or by means of a gear train, in particular planetary gear, driven.
- the vernier motor is arranged coaxially with the spindle.
- the Vernier motor has a relative to the housing rotatably mounted stator, wherein a rotor rotatably mounted within the stator is coupled to the spindle nut.
- magnets are arranged on the outside of the stator, however, compared to conventional electric motors are significantly smaller in size and thus the overall space of the engine is reduced. For this reason, reduces the outer diameter of the actuator.
- the coupling with the spindle nut takes place immediately.
- the spindle nut is driven by the rotor indirectly via an intermediate gearbox.
- the coupling of the rotor is formed with the spindle nut by means of a transmission. This e.g. formed as a gear transmission gear found within the rotor due to the design of the Vernier engine sufficient area of effect.
- the translation possible via the transmission makes it possible to cover a broad application space for adjusting devices with a compact electric linear drive.
- a use of the steering or adjusting device according to the invention as an actuator of a rear axle steering or in a rear axle steering of a motor vehicle is provided. Due to the lower energy consumption of the Vernier electric motor according to the invention due to the above-mentioned higher power density less energy is taken from the electrical system of the motor vehicle for the adjustment of the rear wheels as when using a control device with a conventional electric motor. About the In addition, lower energy consumption during adjustment results in lower operating noise for the actuator. In addition, the weight reduction in the sense of economy in vehicles with rear axle steering.
- the aforementioned drive by means of vernier motor is also suitable for other applications, for example in window regulators in vehicle doors or similar actuators. Again, a compact, energy-efficient and high-torque drive is required.
- the single FIGURE shows in a longitudinal section the construction of a simple, ie only acting on a wheel, electrically driven actuator 1 (also called adjusting device) for a rear axle steering of a motor vehicle.
- the actuator 1 has a multi-part housing 2, in which a spindle drive 3, which comprises a spindle nut 4 and a standing with the spindle nut 4 in engagement, axially displaceable spindle 5, is arranged.
- the spindle 5 has a spindle or external thread 5a and the nut 4 a nut or internal thread 4a, which are formed as a movement thread, preferably as a trapezoidal thread.
- the spindle nut 4 which is rotatably supported by two roller bearings 6, 7 with respect to the housing 2, is driven by a belt drive 8 by an electric motor 9.
- the housing 2 comprises three housing parts, namely a central housing part 2a, in which the spindle nut 4 is mounted, a vehicle-side part 2b, via which the actuator 1 is pivotally mounted on the vehicle, and a wheel-side housing part 2c, arranged on the end face of a sliding bearing 10 is.
- the spindle 5 has a frontal end 5b, which is rotatably and shear-resistant connected to a screw-11.
- the Aufschraubzapfen 11 has a plain bearing portion (without reference numeral), which is guided in the sliding bearing 10.
- a joint 12 is attached via a pivot pin 12a, which is connected via a steering linkage, not shown, for. B.
- a tie rod or directly to a steerable rear wheel of the motor vehicle can be connected, which is rotatably supported and steerable by means of a wheel carrier on the vehicle body.
- the protruding from the housing 2c outer part 11a of the Aufschraubzapfens 11 is sealed by a flexible seal, designed as a bellows 13, on the one hand surrounds the housing 2c and on the other hand, the pivot pin 12a.
- the sliding bearing 10 and the slide bearing 10 sliding sliding portion of the Aufschraubzapfens 11 have an anti-rotation, which is not shown here. It is apparent from the drawing of the small space required by the electric motor. As a result, a slim design of the actuator or of the actuator is achieved overall.
