Definitions
- Parking locks are always used when non-mechanical components are used in a power transmission, in particular in automatic transmissions with hydrodynamic torque converter.
- the accidental engagement of the parking brake - to avoid, for example due to a failure of hydraulic or electrical components - while driving.
- the parking brake should therefore enter with certainty only if the lever position P is actually engaged on the selector lever, or if - as in some automatic transmissions available - the P key was pressed or if - for example, after leaving the vehicle - possibly an automatic Inserting the parking lock was done.
- a parking brake device in which the parking lock pawl also retracts by means of spring storage, and in turn is unlocked by hydraulic pressure from the oil pressure circuit of the automatic transmission with simultaneous compression of the Fe of the memory.
- a mechanical pawl holder of the hydraulic parking brake actuator is provided, wherein the pawl holder is actuated by energizing an electromagnet. As long as the electromagnet is de-energized, the pawl holder is held in the locked position, so that the parking brake remains in the unlocked position. If the electromagnet is energized, the pawl holder is triggered, and the parking brake moves due to the bias of the spring accumulator.
- the holding device or the toggle mechanism
- the holding device is directly connectable to a transmission shift shaft. It is by the transmission shift shaft in per se known manner, the actuating device for engagement or disengagement of the parking pawl actuated.
- the toggle mechanism can optionally be arranged both within the transmission housing and outside of the transmission housing. Due to this flexibility of the arrangement of the holding device or the toggle mechanism is thus a structurally simple and flexible replacement of the known from the prior art, more complex solutions given by the parking brake device according to the invention.
- the holding devices known from the prior art shown in FIGS. 3 and 4 for securing the parking pawl in the disengaged position are in the form of comparatively complicated mechanisms comprising a plurality of individual parts which can be exactly matched to one another.
- such known holding devices for securing the Sperrperrenkhnke bring with it considerable manufacturing costs, and are also relatively sensitive due to their complexity or vulnerable to different environmental conditions, which is why in the known from the prior art holding devices always a well-protected attachment and appropriate supply of lubricant is indispensable ,
- FIGS. 5 to 7 show, in a highly schematic representation only, the holding device for the parking pawl in one embodiment of the invention
