Definitions
- the invention relates to a load adjustment device for a the performance of an internal combustion engine of a motor vehicle determining, especially as a throttle valve trained actuator arranged on an actuating shaft, with a reversible actuator for movement the control shaft between a minimum load position and a Full load position, with a return spring for preloading the control shaft in the minimum load direction and with an emergency running spring for preloading the control shaft in Full load direction in a determined by a stop Emergency running position.
- a load adjustment device of the above type is made known from EP 0 378 737 B1.
- the reversible actuator this load adjustment device has an electric motor for moving the actuator. If the Actuator or its control becomes the actuator by the emergency running spring and the return spring moved to an emergency running position.
- This emergency running position is located between the minimum load position and the Full load. In this emergency running position, the Internal combustion engine a sufficiently large torque to the motor vehicle at low speed from one To move the danger zone.
- the run-flat spring and the Return springs are each designed as steel springs, the spring force of the emergency running spring at least is dimensioned as large as the spring force of the return spring.
- a disadvantage of the known load adjustment device is that they are very complex and expensive is to be manufactured. Furthermore, opposing one another Steel springs vibrate the control shaft and thereby an exact definition of the emergency running position complicate.
- the invention is based on the problem of a load adjustment device of the type mentioned at the beginning that it is particularly inexpensive to manufacture and that the emergency running position is particularly precisely defined leaves.
- the emergency running spring has its own damping, so that the control shaft oscillates reliably is avoided.
- the emergency running position is therefore easy set and will if the actuator fails reliably achieved.
- the emergency running spring also dampens Impacts from the stop on the actuating shaft and thus leads to a low bearing wear of the control shaft.
- the emergency running spring can be compared to the Steel spring of the known load adjustment device very inexpensively manufacture. This leads to a reduction the manufacturing costs of the load adjustment device according to the invention.
- the elastic plastic can for example rubber.
- the load adjustment device according to the invention is designed is particularly compact when the emergency running spring is between the adjusting shaft and one of the return spring against the Stop of the emergency running position movable lever arranged is.
- the load adjustment device can be vote especially easy if the control shaft immediately with an actuator of the actuator in operative connection stands.
- the relationship is the spring forces for determining the emergency running position irrelevant, because in the abutting the stop Position of the lever the emergency running position exclusively is determined by the emergency running spring.
- the emergency running springs and the return spring arranged one behind the other. Therefore is a complex coordination of the emergency running spring the return spring is not required.
- the load adjustment device according to the invention is designed constructively particularly simple if the lever is a the adjusting shaft has a concentrically enclosing sleeve.
- the emergency running spring is according to an advantageous development of the invention for guiding and holding the sleeve designed with the stop if the emergency running spring is ring-shaped, the actuating shaft is designed to enclose.
- the load adjustment device according to the invention particularly few components, which leads to a further reduction of their manufacturing costs.
- the spring characteristic of the emergency running spring can be according to a other advantageous development of the invention simply adjust if the ring-shaped emergency running spring Has recesses.
- the ratio of the size of the recesses to the mass and arrangement of the elastic Plastic determines the spring characteristic of the emergency running spring.
- the load adjustment device can be Assemble particularly easily if the emergency running spring is integral with the sleeve and with a rotationally fixed on the Actuating shaft attached socket is connected.
- the emergency running spring is integral with the sleeve and with a rotationally fixed on the Actuating shaft attached socket is connected.
- This structural unit can then be easily in their intended position mount on the shaft. It can also Emergency running position of the control shaft when it touches the stop Simply set the lever.
- the emergency running position can be advantageous according to another Subsequent development of the invention is simple adjust when there is an angle of rotation between the socket and the control shaft is adjustable.
- Load adjustment device helps when the lever and the sleeve are made in one piece from plastic are.
- An intended spring force of the emergency running spring in the emergency running position can be according to another advantageous development simply ensure the invention when the Sleeve or the bushing a pretensioning lever for pretensioning the emergency running spring and when the pretensioning lever is in the emergency running position against the stop of the other component is biased.
- the setting of the spring force of the emergency running spring in the emergency running position is designed according to another advantageous Development of the invention is particularly simple, if the sleeve has a projection, being on a Side of the projection the stop and on the stop opposite ramp arranged is. Furthermore, the projection has by its arrangement large dimensions on the sleeve and thus high stability.
- FIG. 1 shows a portion of a housing 1 a Throttle body one for power control one Not shown internal combustion engine provided Load adjustment device.
- a Throttle valve shaft trained control shaft 2 mounted, on which a schematically illustrated throttle valve 3 is arranged is.
- the actuating gear 6 has a servomotor 7, which has a Drive pinion 8 a large-diameter intermediate gear 9 drives.
- This intermediate gear 9 is in one piece with one diameter small gear 10 made and on a Axis 11 mounted.
- the toothed segment 4 Position 5 is permanently engaged with the on the Intermediate gear 9 arranged gear 10.
- the throttle body is designed as a torsion spring Return spring 12.
- One end of the return spring 12 is on a lever 13 connected to the control shaft 2, while the other end is attached to a housing Stop 14 supports. Furthermore is on the case 1 a stop 15 for the connected to the control shaft 2 Lever 13 arranged.
- FIG. 2 shows a partially sectioned view perpendicular to the throttle valve assembly from FIG the actuator 6. It can be seen that the with the control shaft 2 connected lever 13 on a sleeve 16th is arranged. On the inside of the sleeve 16 is one ring-shaped, made of an elastic plastic Emergency running spring 17 attached.
- the throttle body shown in an emergency position, in which the servomotor 7 shown in Figure 1 is de-energized is and the emergency running spring 17 and the return spring 12 Preload throttle valve 3 in the position shown.
- Figure 3 shows in a greatly enlarged sectional view by a partial area receiving the emergency running spring 17 the control shaft 2.
- the made of elastic plastic manufactured emergency running spring 17 is cohesive on one Bush 18 attached.
- the socket 18 is provided in one Rotary position in which the in Figures 1 and 2 shown throttle valve 3 in the intended position is welded to the control shaft 2.
- the socket 18 can also have an internal multi-tooth have and on a correspondingly designed External spline of the control shaft 2 must be attached.
- the run-flat spring 17 has to generate a spring characteristic curve a recess 19.
- Figure 4 shows in perspective one of an elastic Plastic-made, between a sleeve 20 and one Socket 21 arranged emergency running spring 22.
- the sleeve 20 and the socket 21, like that from FIG. 3, serves for transmission of a torque on the non-rotatably connected to the socket 21 Control shaft 2.
- the sleeve 20 has a lever 23 for Articulation of the return spring 12 shown in FIG. 3.
- a biasing lever 24 is arranged on the bushing 21.
- the Sleeve 20 has a projection 25 with a stop 26 on, against which the biasing lever 24 is biased. This indicates the emergency running position. With a movement of the Control shaft 2 shown in Figure 1 in the direction of minimum load position the biasing lever 24 moves away from the stop 26.
- the projection 25 in the biased position shown the projection 25 has a ramp 27.
