Gear cluster and the motor-driven gear group that is used for cable window lift systems

Technical field

The present invention relates to a kind of gear cluster and relate to a kind of motor-driven gear group that is used for self-propelled vehicle cable formula window lift systems.

Background technology

For the existing many requirements of motor-driven gear group that are used for self-propelled vehicle cable formula window lift systems, in fact mean the parameter area of relative narrower aspect structure design.Particularly, in structure design, must consider following limiting factor: the horsepower output that is used for the electrical motor of motorized motions; The available on-board power that has the self-propelled vehicle of influence for maximum output power; Predesignated the friction force that structure design brought by window lift systems of required minimum output power; Be directed to the window lift systems on the self-propelled vehicle Qianmen and the structure design of the window lift systems on the self-propelled vehicle back door simultaneously; Adjust the desired range of vehicle window; In the self-propelled vehicle useful life, maximum number of times that the window lift systems of being expected starts; Be used for the optional design of manual and motorized motions window lift systems; The bending strength and the durability of the cable that uses.In fact, also must consider other a large amount of limiting factors.

In fact, these requirements cause being had usually by the window lift systems that the turbine drop-gear box drives and are in the interior gear ratio of scope from about 1: 62 to about 1: 84, wherein, the cable reel has the diameter in being in from about 36mm to about 48mm scope usually, and the normally about 20W of the horsepower output of electrical motor.Since in any correction, must be optimized for a large amount of conditions, as indicated above, be very difficult so in fact depart from the parameter area of these relative narrower.

In fact, some above-mentioned parameter and other parameter almost can't change, because may produce serious technical matters.For example, the higher relatively defective of cable coiling on the reel is supervened in may reducing of cable drum diameter, this defective makes aspect the cable guiding and produce very big problem aspect the structure design of cable window lift systems, and supervene the crooked largely significantly defective of cable, this defective will poorly influence the durability of the cable that will guarantee in the whole useful life of self-propelled vehicle.

Nowadays, auto-industry more and more require generally to use the normalisation accessory part.This measure reduces cost aspect structure, storage and assembling.Particularly, nowadays, for this reason, electronic cable window lift systems on Qianmen and the back door is provided as having the unit of capability for the electrical motor of 20W, yet the above-mentioned fact has a defective: the place must provide in fact also unnecessary excessive structural volume at the back door.This is to locate introducing usually on one point because vehicle rear window also has dual boot and propulsive effort usually on door, and therefore, friction or tilt problem are not very important.Because space and cost, so need provide electronic cable window lift systems with low horsepower output.Yet, the relative higher requirement before adjustment aspect the vehicle window, the vehicle window guiding that especially has the relative complex of lower mechanical efficiency etc. hinders reaching of this target.

In whole process, must consider this fact, that is: in the design of the motor-driven gear group of gear cluster or cable window lift systems, even very small improvement, for in the automobile supporting industry for the given most current cost pressure, all have cooresponding economic implications.

Fig. 8 shows the gear cluster that is used for electronic cable window lift systems according to prior art with a cross sectional drawing.Only show the gear case part 6 of gear cluster, wherein accommodate the turbine 10 of gear on worm.Axle drive shaft (not shown) extends through the cylindrical hole of gear case part 6 right hand edges, is fixed with one at the front end of this axle drive shaft and drives worm screw 15, and its tooth is engaged in the tooth 11 of turbine 10.For the above reasons, in the prior art in this way the gear of design-calculated gear on worm ratio be in from about 1: 62 in about 1: 84 scope.

What be fixed in gear case part 6 upper ends is the driving claw-shaped device 40 that the upper end has a conical trough of belt tooth 41, is mounted with the cable reel (not shown) with internal tooth on conical trough of belt tooth 41, makes it fixing when rotated.Turbine 10 is designed to a hollow body, and wherein reinforced rib (not shown) is arranged to have angular separation ground each other.Be meshed with reinforced rib so that claw-shaped device 40 is connected to turbine 10 to have the rubber damping element of arranging on respective corners spacing ground 39 each other, make it fixing when rotated.Install and drive claw-shaped device 40 and turbine 10, so that they can be together around trunnion 9 rotations.It is fixing to prevent its displacement on axis direction with turbine 10 to drive claw-shaped device 40 via set collar 35.Cable reel (not shown) cable with the unwinding cable window lift systems that is used in a known way reeling.

Be fixed on the gear case part 6 is a upper end case lid 32, in the annular space on wherein a sealing member 30 with sealing lip 31 being fixed between the outer periphery edge of case lid 32 inner peripheral walls and turbine 10 upper ends, so that turbine 10 and driving claw-shaped device 40 are sealed with respect to gear case part 6.

The horsepower output high relatively according to the prior art electrical motor (20W) and correspondingly big driving torque make needs to a certain degree damping really in the conventional transmitting set drive gear set of being showed.The multiple component design that drives train is relative complex and costliness, and it comprises the driving claw-shaped device, is connected to the deformable rubber damping element (it is engaged in corresponding reinforced rib on the turbine inner peripheral in mode next to the shin) and the turbine of this claw-shaped device.

Corresponding to WO 99/47779, the applicator of DE 198 12 875 C1 discloses a kind of cable type and activates the window elevator driver train, and it only is made up of the few components with appropriate tolerance.Engine shaft is integrated on the bearing cap shim of gear drive unit.On the periphery edge of the teeth parts of cable reel and/or gear drive unit, provide a sealing member.

Summary of the invention

A purpose of the present invention is to provide a kind of gear cluster or motor-driven gear group in a kind of cable window lift systems that can generally be used on self-propelled vehicle back door and the Qianmen is provided that it has simpler design and can produce more cost-effectively.

According to the present invention, a kind of gear cluster that is used for self-propelled vehicle cable formula window lift systems is provided, it comprises an actuating device and a gear mechanism, this gear mechanism is cooperated with this actuating device and is coupled on the cable reel of rotary installation, be used for reeling and the unwinding cable window lift systems in cable.According to the present invention, gear cluster is characterised in that the cable drum diameter is in from about 22mm in about 30mm scope, and preferably be in the scope from about 24mm to about 28mm, wherein the gear of gear mechanism ratio be in from about 1: 38 in about 1: 55 scope, and preferably be in about 1: 42 in about 1: 51 scope.

Because according to the present invention, make the cable drum diameter significantly less than conventional gear cluster, and correspondingly change the surprising simple measure of gear mechanism gear ratio simultaneously, so, according to the present invention, less and lower-powered driving driving engine may be used for rear cables formula window lift systems.Particularly, can use according to the present invention and have maximum output power and only only be the driving motor of about 6.0Nm for about 10W and maximum driving torque.Be found to be and make gear cluster according to the present invention can be used in electronic and the manually operated cable window lift systems, this design modification is very crucial.

This is because broad research that the applicator did shows: cause the anticipation of the unaffordable high pressure of cable and therefore fractureed before the conventional useful life of self-propelled vehicle finishes cable or similar view opposite with like this one little cable drum diameter, in the driving engine situation that significantly reduces according to power used in the present invention, to such an extent as to the maximum enough low cable of cable pressure is sustainable until the conventional useful life end of self-propelled vehicle.

Particularly, found that it is not frequent use that the motor vehicle rear vehicle window is compared with anterior vehicle window, and the range of rear portion vehicle window is also less usually.Therefore, opposite with above-mentioned anticipation, although less cable drum diameter can be used in the rear portion window lift systems really and/or has than minor diameter, the axial length of cable reel remains enough, cable can not crossed the highland and be wound up on the reel.

Simultaneously, also can be used in the anterior cable window lift systems according to gear cluster of the present invention.Although this is because cable drum diameter according to the present invention is significantly less, can obtain sufficient throw of lever (comprising) for anterior cable window lift systems, with in addition in having sufficient driving torque, lower-powered electrical motor situation, adjust vehicle window.Even, can guarantee the durability of cable abundance therefore, for anterior cable window lift systems.

According to the present invention, the gear ratio of the gear of gear mechanism ratio, especially gear on worm and is compared in the prior art, has reduced the ratio identical with the minimizing of cable drum diameter.Therefore, it is favourable corresponding essentially to conventional cable window lift systems according to the cable forces/cable velocity characteristic curve of cable window lift systems of the present invention.

Become according to the present invention the significantly lower output torque of possible electrical motor with and lower horsepower output make and may the cable reel preferably and directly be coupled to gear mechanism according to the present invention, particularly be coupled on the turbine of gear mechanism.Therefore, according to the present invention, can omit and use the extra damping element that requires to be used between axle drive shaft and driven shaft, carrying out damping in the prior art.Therefore, surprising simple designs correction according to the present invention has extra advantage: gear cluster can design in comparatively uncomplicated mode, and according to the present invention this measure make the design and assembling aspect quite saving cost.

According to the present invention, the cable reel is coupled on the turbine by at least two engaged elements, these at least two engaged elements are arranged on the cable reel end side, and be engaged in mode next to the shin at least two opposition elements of turbine end side, these opposition elements are designed to corresponding to these engaged elements.These engaged elements are preferably designed so that projection, claw-shaped device for example, and it is engaged in the groove of respective design.

Owing to no longer require to be coupled to the driving claw-shaped device of turbine according to the present invention, therefore, the gear case of gear cluster part also can be sealed in simpler mode according to the present invention.For reaching this purpose, preferably be fixed on turbine outer periphery edge in a mode sealing arrangement or on gear case part upper limb, so that it is fixing when rotated.

This feature allows to produce with assembling process and compared with prior art takes place to change significantly.For example, sealing arrangement also can together form with other sealing arrangement in an operation, for example: the sealing of electronic shell part, electrical motor is sealed with respect to shell and similar sealing.For reaching this purpose, also can especially utilize two assembly injection moldings (2C injection molding), wherein in case first assembly (for example, relative hard shell) solidifies, hole in the mould enlarges so, and then, inject second assembly (for example, relatively soft sealing arrangement) via second injection device.In addition, can promote turbine and pass a sealing arrangement of having used and enter the gear case part, and therefore, only can be placed on the turbine with the top cover cap, therefore can save a large amount of operations according to prior art (referring to Fig. 8) sealing arrangement.

Because cable reel according to the present invention is directly coupled to turbine, particularly, be engaged to the end side of turbine, so window lift systems can optionally be designed to according to the present invention manually or motorized motions and need not other design modification in mode next to the shin.Particularly, identical cable reel, identical base plate (being used for gear cluster or motor-driven gear group are fixed on the guide rail of (for example) cable window lift systems) and identical cover plate can be used for manually reaching in the electronic cable window lift systems.

In order to receive brake spring or the winding spring (wrapspring) that is used for manual cable window lift systems, an engaged element (particularly a, claw-shaped device) can comprise a shoulder is used for receiving brake spring or winding spring with formation pedestal.

According to other aspects of the invention, also provide a kind of motor-driven gear group that is used for self-propelled vehicle cable formula window lift systems.According to the present invention, this motor-driven gear group is characterised in that motorcoupling to gear cluster, and this electrical motor has the driving torque of maximum about 5.7Nm and/or the horsepower output of the highest about 10W.

According to the present invention, a motor-driven gear group like this can be used in the cable window lift systems of the cable window lift systems of anterior motor vehicle automobile door and rear portion motor vehicle automobile door.

Owing to can have significantly less maximum torque according to electrical motor of the present invention, so the outside dimension of motor-driven gear group can be significantly less according to the present invention.According to the present invention, in the motor vehicle automobile door or wait to be incorporated into the structural volume that is contained in the door module on the door and can reduce about 40% or even reduce 50%.In a word, this measure makes and compared with prior art further saves cost significantly.
