Definitions
- the invention relates to a method for increasing a torque of a prestressed spring arranged about a rotating body having a longitudinal axis, and to a use of the method.
- Methods for increasing the torque of preloaded springs are known. It is provided, for example, to arrange the prestressed spring around a rotatable shaft. Both ends of the preloaded spring are fixed to stops that belong to the rotatable shaft. It is often desired that the preloaded spring mounted in this way is rotated for a first angular path without the application of force. After a maximum of one full rotation of the rotatable shaft, one end of the spring is brought to a stop, which is usually assigned to a housing part.
- the invention is therefore based on the object of providing a method for increasing a torque of a prestressed spring arranged about a rotating body having a longitudinal axis, in which it is possible for the Initiate an increase in torque only after several turns of the preloaded spring without additional force.
- the invention also provides a use of the method for increasing the torque.
- the object on which the invention is based is achieved by a method for increasing a torque of a pretensioned spring arranged about a rotating body having a longitudinal axis, the first end and the second end of which are positioned in the state of pretensioning on a first stop or on a second stop , which are connected to the rotating body, in which the rotating body first makes at least X revolutions about a longitudinal axis without external force, the first end engaging once in each revolution in a cam wheel which has at least X + 1 teeth and at least one parallel to the teeth arranged cam, and this rotates by one tooth per revolution of the rotating body, in which the rotating body is continuously subjected to the rotary movement in the state of pretension after at least X revolutions, the cam wheel with its cam abuts a third stop and the first end in the N engages ockenrad and in which finally the rotary movement is continued, the first end in engagement of the
- Cam wheel remains and its positioning is canceled at the first stop.
- the existing torque in the initial state is the torque that is set by the preload of the spring.
- the first end of the preloaded spring is positioned in the first stop.
- the second end of the spring is positioned in the second stop.
- Both the first stop and the second stop are connected to the rotating body. This can be a direct connection. However, it is also possible to connect the first stop or the second stop to the rotating body via at least one connecting part.
- the rotating body initially leads without an external one Force applied at least X revolutions around its longitudinal axis, which represents the axis of rotation. Without the action of force here means without the action of forces on both the first end and the second end of the prestressed spring.
- At least X revolutions means that the number of revolutions must not be an integer but greater than 1. This depends on the starting position of the first end of the preloaded spring in relation to the position of the arrangement of the cam wheel.
- the cam is arranged parallel to the teeth. This does not mean that the cam necessarily has to be arranged directly adjacent to a tooth of the cam wheel. For example, it may also be possible to arrange the cam in a plane parallel to the plane of the teeth between two adjacent teeth.
- a preferred embodiment of the invention consists in that the prestressed spring is arranged around a shaft arranged as a rotating body. This facilitates the arrangement of the prestressed spring around the rotating body and avoids damage to the prestressed spring, which could arise, for example, from a square material that is used as the rotating body.
- the engagement of the first end of the spring in a self-locking cam wheel takes place.
- a cam wheel is used as a self-locking cam wheel
- Frictional forces is self-locking. This is to be understood to mean that the cam wheel is not set to rotate independently without external force or does not continue to rotate independently after the action of the external force.
- the cam wheel is releasably held in its position after each partial rotation around a tooth by a ball engaging between two adjacent teeth.
- the ball is usually pressed against the cam wheel by a spring force.
- the cam wheel rotates one tooth further, the ball snaps into the adjacent gap between two adjacent teeth of the cam wheel, for example due to a spring force acting on it. In this way, an independent further turning of the cam wheel beyond a single tooth is advantageously avoided in a particularly advantageous manner.
- a further embodiment of the invention provides that the cam is brought to bear on a third stop, which is part of the housing of a structural unit which consists of the rotatably mounted cam wheel, the ball, a stop and a compression spring arranged between the ball and the stop.
- a third stop which is part of the housing of a structural unit which consists of the rotatably mounted cam wheel, the ball, a stop and a compression spring arranged between the ball and the stop.
- the second end of the spring is positioned in a bore arranged in the rotating body as a second stop. In this way, space is advantageously saved.
- the engagement of the first end in the cam wheel takes place with a sleeve arranged at the second end.
- the sleeve is made, for example, from a relatively soft plastic material.
- the invention relates to the use of the method in an actuator for setting a valve lift of a motor vehicle.
- the setting of the valve stroke should be carried out in a relatively simple manner, which can be easily achieved by the method according to the invention.
- Fig. 1 shows the rotating body with a preloaded spring and the cam wheel in three-dimensional form.
- Fig. 2 shows the top view of the rotating body and the cam wheel and the preloaded spring after three rotations in the preloaded state.
- Fig. 3 shows a plan view of the rotating body and the cam gear in the state of the fourth revolution to be initiated in the state of the pretension of the prestressed spring.
- Fig. 4 shows a top view of the rotating body and the cam gear after the fourth revolution has been initiated in the state of the pretension of the prestressed spring.
- FIG. 5 shows a top view of the rotating body and the cam wheel shortly before the fourth rotation is completed in the state of the pretensioning of the pretensioned spring.
- Fig. 6 shows a top view of the rotating body and the cam gear in the state of the continued rotary movement after the positioning of the first end has been canceled at the first stop.
- Fig. 7 shows a unit consisting of cam wheel, ball, stop and compression spring in three-dimensional form.
- FIG. 8 shows a device for increasing a torque of a pretensioned torsion spring according to the prior art, arranged about a rotating body having a longitudinal axis, in longitudinal section.
- Fig. 1 the rotating body 1 designed as a shaft and the preloaded spring 2 are shown three-dimensionally.
- the first end 2a of the prestressed spring 2 engages with its first end 2a and the arranged sleeve 10 in a cam wheel 3 which has at least X + 1 teeth 3b.
- the cam wheel 3 is rotated further by one tooth 3b per revolution of the rotating body 1.
- the first end 2a is in the state of
- the cam wheel 3 is rotatably mounted in a housing 5 via an axis 4.
- the housing 5 belongs to a structural unit consisting of the rotatably mounted cam wheel 3, a ball 7, a stop 9 and a compression spring 8 arranged between the ball 7 and the stop 9.
- the ball 7 is designed such that it can engage in the gap between two adjacent teeth 3b. In this way, the cam wheel 3 can be releasably positioned, thereby ensuring that the cam wheel 3 does not rotate further than a single tooth 3b per revolution of the rotating body 1.
- the first stop 1a is connected to the shaft arranged as a rotating body 1 via a connecting part 1c. However, it is also possible to arrange the first stop 1a directly on the rotating body 1.
- the cam gear 3 has five teeth 3b and it is initially provided that the rotating body 1 be made four revolutions around its longitudinal axis without external force before an increase in the torque is initiated.
- there is a positioning as shown in FIG. 2, provided the rotary movement has been initiated, as the first end (2a) between two teeth (3b) of the cam wheel ( 3) was engaged.
- the shaft 1 rotates clockwise in the direction of the arrow. No additional external forces act on the preloaded spring 2.
- the first end 2a of the prestressed spring 2 lies against the first stop 1a, which is connected to the rotating body 1 (not shown).
- the first end 2 a has an arranged sleeve 10, which is intended to facilitate engagement with the cam wheel 3.
- the cam wheel 3 is rotatably mounted on the axis 4 and has a cam 3a which is arranged directly adjacent to a tooth 3b parallel to the plane of the teeth 3b.
- the cam wheel 3 and the cam 3a are usually advantageous as an individual part manufactured.
- the second end 2b of the prestressed spring 2 is positioned in a bore in the rotating body 1 arranged as a second stop 1b.
- a ball 7 engages in the gap between two adjacent teeth 3b of the cam wheel 3 and is pressed against the cam wheel 3 by the compression spring 8, which rests on a stop 9 on its side facing away from the ball 7. Due to the further rotation of the shaft arranged as rotating body 1 in a clockwise direction, the cam 3a moves towards a third stop 6, which is either arranged in a housing (not shown) or in
- FIG. 3 shows a top view of the rotating body 1 with the cam wheel 3.
- the rotating body 1 has been rotated further clockwise, which has led to an engagement of the first end 2 a in the cam wheel 3 , This intervention simultaneously ensures that the ball 7 is moved against the force of the compression spring 8 in the direction of the stop 9.
- FIG. 4 shows the top view of the rotating body 1 and the cam wheel 3, which results as a further revolution of the rotating body 1 from the position shown in FIG. 3.
- the ball 7 has been brought into a position between two teeth 3b of the cam wheel 3 again by the force of the compression spring 8.
- the cam 3a now lies firmly on the third stop 6.
- FIG. 5 shows the top view of the rotating body 1 and the cam wheel 3 shortly before the end of the last rotary movement in the state of the pretensioning of the prestressed spring 2.
- the second end 2a now engages again in the cam wheel 3, but this is due to the cam being in contact 3a on the third stop 6 cannot be rotated counterclockwise again by a further tooth 3b.
- a further rotation of the rotating body 1 in a clockwise direction thus leads to the second end 2a remaining in the cam wheel 3 in the position shown.
- FIG. 6 shows the top view of the rotating body 1 and the cam wheel 3 starting from the position shown in FIG. 5.
- the rotary movement has meanwhile been continued, the first end 2a remaining in the engagement of the cam wheel 3 and its positioning at the first stop 1a having been canceled.
- This has been realized in that the first stop la has continued to perform the rotary movement.
- the torque present through the preload is further increased, the angle ⁇ representing the additional angle of rotation.
- a structural unit which consists of the rotatably mounted cam wheel 3, the ball 7, a stop 9 and a compression spring 8 arranged between the ball 7 and the stop 9.
- a part of the housing 5 of the assembly simultaneously forms the third stop 6 for the cam 3a of the cam wheel 3.
- the assembly is relatively compact and can also be retrofitted in a particularly advantageous manner.
- FIG. 8 shows a rotating body 1 * with a prestressed spring 2 * according to the prior art in longitudinal section.
- the pretensioned spring 2 * is positioned with its first end 2a * and its second end 2b * at a first stop la * and at a second stop lb *.
- the rotating body 1 * can make a maximum rotation of 360 °.
- the first end 2a * of the prestressed spring 2 * comes against a fourth stop 3 *, which is, for example, firmly connected to a housing. at further rotation automatically increases the torque, which in many technical cases is only desired after further rotations in the state of the preload of the preloaded spring 2 *.
- This prior art procedure is therefore extremely disadvantageous.
