Definitions
- the invention has for its object to drive the tailgate of a vehicle as efficiently and economically as possible.
- this is usually a hydraulic cylinder with a very high energy density or an electromechanical spindle drive, usually equipped with a planetary gear.
- the drive must be feasible in a small space, both diameter and length
- the electric motor provides the energy required to move the tailgate.
- the electric motor must be a hollow shaft motor, this can be a DC motor or an electro-commutated motor (EC).
- EC electro-commutated motor
- an EC motor as they are more durable, allow a more favorable torque curve and have less noise due to the lack of collector.
- the gearbox converts the torque introduced by the electric motor into the required linear motion in a single gear stage.
- the rolling movement of the inner ring and the relatively slow speed cause low friction and low noise, which ensures high efficiency in the single-stage gearbox.
- the transferable linear force can be varied by switching gear stages in series.
- the gearbox also allows individual connection or decoupling of the rotating gear from the linear movement.
- the coil spring serves to store the potential energy of the tailgate by spring tension between.
- a spiral spring can also act inside the spindle, a gas spring, which caches the potential energy as a pressure.
- the tailgate can be kept approximately balanced in any position. To move the tailgate of the electric motor only the differential force between the tailgate and spring and acceleration forces must be applied.
- the linear drive is held in place with the preset force of the hydraulic brake. If this is overcome, the linear drive can be moved freely manually.
- the linear drive When using a spiral spring, the linear drive is virtually insensitive to temperature influences and brings about the same power over a wide temperature range. Advantage of the linear drive:
- the advantage of the linear drive is, on the one hand, that the transmission itself is switchable and thus separable from the spindle. An additional system is not required for this purpose.
- the spindle is fully released. The desired manual operation can be freely designed.
- the axial force can be varied by the number of gear stages.
- the arrangement of the driving ring bearings to the fine thread spindle allows a very compact gear and thus a high single-stage translation with high power transmission in the smallest space.
- the electric motor Due to the high efficiency of the transmission, the electric motor can continue to be designed relatively small and thus a small space can be realized.
- the spindle does not require torsion protection for the housing.
- the arrangement of gear and electric motor outside the spindle can be integrated in its interior other functions such as the holding function of a hydraulic brake or a gas spring.
- the specified by the transmission speed for the electric motor falls into a pleasant sonorous range. Due to the structure, only slight noises are caused in the gearbox.
- the force to be transmitted axially depends on the number of driving ring bearings (1.2) used, which act directly on the fine thread.
- the fine thread spindle (1.1) over its entire length which is not limited by otherwise required components, have the same diameter. This results in high power density of the linear drive to a space advantage.
- the drive unit (4.14 and 4.15) with the large outside diameter thus does not have to go over half the cylinder length, but is defined by the required axial force.
- the length of the cylinder can reach up to the kink length.
- the linear actuator can be designed as a highly integrated system in the smallest possible space and combines the advantages of the hydraulic and electromechanical linear drives commonly used today.
- the transmission is a single-stage switchable transmission with a fixed ratio.
- the driving ring bearing (1.2) When operating the latching device (1.3), the driving ring bearing (1.2) is brought into an eccentric position to the fine thread spindle (1.1).
- the driving ring bearing (1.2) must be aligned at an angle corresponding to the thread pitch at an angle to the fine thread spindle (1.1).
- the transmission may alternatively be a non-shiftable transmission in a basic version.
- the element to be moved remains in the stopped position.
- the driving ring bearing (1.2) is fixed by the thrust bearing (2.5) in the direction of action. If now the thrust bearing (2.5) driven by rotation, so the axially fixed drive ring bearing outer ring (2.3) is taken and roll the bearing balls (2.2) in the drive ring (2.1) from.
- the drive ring (2.1) engages over the radial grooves (2.4) in the thread of the fine thread spindle (1.1). About the rolling of the bearing balls (2.2) of the drive ring (2.1) is pressed circumferentially in the fine thread spindle (1.1) and screwed in this way along the spindle.
- the engagement device or disengagement device can be actuated manually or via a control.
- the control is activated when electronics eliminate the need for latching or disengaging the drive ring bearings recognizes.
- the control may be, for example, an electrically driven lever or plunger, driven by a motor or lifting magnet.
- the required axial force can be applied over a wall thickness to be defined. If the transmission of the axial force on the wall thickness determined so, then the material core of the fine thread spindle (1.1) is not needed.
- This can thus be designed as a fine thread spindle tube (2.7), so hollow and the interior for other functions, e.g. be used as a gas spring (6.8) or as a hydraulic brake (4.19).
- the axial force is transmitted via the crescent-shaped thread overlap (3.1) between fine-threaded spindle (1.1) and radial grooves (2.4).
- the amount of the axially transferable force can be variably adjusted or designed structurally by the number of driving ring bearings (1.2).
- Fig. 1 1 is a schematic diagram of a single-stage hydraulic brake is shown, which can of course also be carried out in two stages depending on the requirements.
- the invention is illustrated by way of example in the following drawings and will be described in detail with reference to the drawings. Individual elements of the representations are numbered consecutively and assigned to the drawings by the first number before the point.
