- the invention relates to a parking brake, in particular for a motor vehicle, with a cable drive.
- An abovementioned cable drive is known, for example, for actuation of a brake cable in a vehicle, wherein a pulling spindle acting on the brake cable is self-locking.
- a lock is produced which permanently maintains a blockage of the brake and counteracts a release of the brake.
- a disadvantage of this cable drive is that the drive motor of the cable tensioning device must have a high drive torque.
- a Seilzugan ⁇ drive which has an internal, frictional or positive brake-holding device with an additional motor drive having Direction gear.
- This cable drive is very complex in construction and expensive due to its two drive motors.
- a motor vehicle-operated parking brake and a method for controlling it are generally known for a motor vehicle.
- an electric motor with a current sensor serves as a drive for a brake cable by means of a threaded rod having a gear, wherein the electric motor is stopped as soon as the current sensor for the electric motor signals a predetermined value.

- the invention has for its object to provide a Feststellbrem ⁇ se of the type mentioned, which can be equipped with a simple construction with a comparatively low Antriebsnavmo ⁇ ment having drive motor.
- the first object is achieved according to the invention by providing a brake train which is parallel to the drive train and which connects the motor output drive cable to the cable, and which has a self-locking feature.
- the cable pull drive In the cable pull drive according to the invention, a tension force is applied to the cable via the drive train of the transmission, whereas holding the cable tension takes place by means of the self-locking brake cable.
- the brake train serves as a braking or blocking element for the cable drive itself, to the rope tension at a certain level hold.
- the powertrain has no self-locking. It can be constructed smoothly, and it is only a small, a comparatively low drive torque having drive motor required. This results in a weight reduction and a reduction in the power consumption for the cable feed drive, which makes it particularly suitable for use in objects to be moved, such as vehicles.
- the cable drive according to the invention has a short reaction time, he can tighten the rope very quickly and accurately.
- the ver ⁇ reduced power consumption of the drive motor is advantageous for control and regulation of the engine, which can be designed simplified and inexpensive.
- the Geisseschentwick ⁇ development of the cable drive according to the invention is low, especially since a second or further drive motor is eliminated. Due to the relatively small number of individual parts, the manufacture, assembly and maintenance of the cable drive is basically simple and inexpensive.
- the high level of operational reliability and the simple construction make the cable drive according to the invention particularly suitable, for example, for use as a drive for an electric parking brake, such as. It is used for example in Bauma ⁇ machines or motor vehicles.
- the construction of the cable drive is further simplified if an adjusting spindle acting on the cable is provided as the output member of the transmission.
- the drive train and the brake train have different ratios.
- Demge ⁇ gene undergraduate the cable drive on very few components and is very reliable, if according to another advantageous development of the invention, the drive train and the brake train with the same speed act on the Stellspmdel.
- the drive train and the brake train which are each driven only by the drive motor, the same (overall) translation.
- the drive train on a spur gear is inexpensive to manufacture, and it can be transmitted via it drive power with very high efficiency.
- the required Antrj ebs- performance which must make the drive motor to operate the Seilzugan- drive at your disposal.
- a force sensor is provided for detecting a tensile force of the cable.
- the drive motor can be switched off when a preset cable tension is reached, thereby avoiding overstressing the cable.
- the force acting on a device to be operated by the cable for example a braking device, can also be detected by the force sensor and optionally controlled together with the drive motor.
- a motor for example, a hydraulically or pneumatically operated motor to introduce.
- the drive motor is an electric reversible motor.
- Em Reversiermotor also offers the further advantage that it can be used without additional facilities, such as a reverse gear, not only for tensioning the rope, but also for its specific, finely resolved loosening and relaxing.
- the motor drive 1e has a driver, which can be attacked by a driver of the drive train input gear and by a driver of the braser drive gear, driving the drive train gear and / or the brake train gear. In this way, with a simple structural design, a targeted, reliable torque and torque transmission is ensured.
- the An ⁇ powertrain speed is biased against its bias against the driving direction during tensioning of the cable against the engine output shaft.
- the tensioned by the drive motor rope is a brake cable of the actual braking device of the parking brake.
- the brake line in the cable drive which brake line holds the tension in the Bremssei].
- the parking brake according to the invention is particularly suitable for use as a parking brake of a motor vehicle because of its precise metering, reliable function and its simple, maintenance-free construction.
- the parking brake according to the invention has the additional advantage that, with simple measures, for example the use of a force sensor for measuring the tensile force of the brake cable and a control of the drive motor dependent on the tensile force values, a (mechanical) readjustment of the parking brake becomes superfluous; It can then always develop its optimum braking action within very wide limits, without, for example, elongation of the brake cable leading to a reduction in the braking effect.
- Figure 1 shows a cable drive in a perêti ⁇ vischen representation
- Figure 2 shows the cable drive of Figure 1 in one
- FIGS. 3a to 3d each show a section through the cable pull drive according to FIG. 1 in different operating states.
- Figure 1 shows a perspective view of a cable drive 1 with a base plate 2, which holds the drive motor 3 of the cable drive 1, an electric motor with a base plate 2 by cross-motor output shaft 4.
- a transmission 5 connects the engine output shaft 4 with a cable 7 connected to a non-self-locking adjusting spindle 6.
- the cable 7 can be, for example, a brake cable of a parking brake of a motor vehicle not shown here.
- the drivetrain 8 has a spur gear i'9 with a first spur gear seated on the engine output shaft 4 as drive input wheel 10, further spur gears 11, 12 and a last spur gear arranged on the adjusting spindle 6 as the driveline output gear 13.
