Definitions

  • the invention relates to a spur gear differential, in particular for motor vehicles, having the features of the preamble of claim 1.
  • Differential lifts have long been known in various forms. They serve, for example, in the drive train of motor vehicles for speed compensation of the left and right drive wheels when cornering, since in each case different rolling paths are covered.
  • a known design of such Differenzialgethebe has a plurality of meshing bevel gears and is usually referred to as bevel gear differential. Normal differential lifts without a blocking effect are also referred to as open differences, in which the two wheels can rotate freely without appreciable friction losses.
  • Differenzialgethebe Since such open or unlocked Differenzialgethebe be perceived as disadvantageous depending on the purpose of the vehicle equipped with it, also teilgesperrte Differenzialgethebe are used in which the efficiency of an open differential is deteriorated by targeted measures, thus preventing the free rotation of the wheels to each other.
  • Such so-called limited slip differentials can improve traction by redirecting the drive torque from one wheel with greater slip to the other wheel with the better ground traction so as to improve the overall traction of the vehicle under difficult conditions and / or off road terrain.
  • the locked differential the poor traction of the lightly loaded bend inside the wheel can be compensated by the fact that the drive torque is passed to the outside wheel.
  • a locked drive axle can provide better directional stability, eg. In case of sudden crosswind.
  • a locked differential lift is felt to be advantageous at higher speeds and when cornering in the so-called border area, since the slip of the respective inside wheel is reduced, so that a higher cornering speed can be achieved.
  • an understeer tendency of the vehicle is reduced because an uneven force distribution at the wheels due to the changed torque distribution on the outside wheel generates a yawing moment about the vehicle's vertical axis, which favors a screwing in of the vehicle or its oversteer. If this blocking effect also exists in overrun mode, the power flows are reversed so that the resulting yaw moment causes increased understeer and thus stabilization of the vehicle.
  • Such a characteristic can be used particularly advantageous in sporty moving vehicles as well as in racing.
  • a known differential gear with limited slip can be found in DE 24 53 489 A1. At high loads, high preload forces should be generated and under low load a reduced preload should be generated.
  • the variable bias should be achieved by means of clamping means associated with the side gears. The biasing means urge the side gears in a direction opposite to the direction of the axial forces imposed on the side gears via the planetary gears. Further designs of such spur gear differential lifts are known from DE 10 2007 004 710 A1 and from DE 10 2007 004 712 A1.
  • a common feature of conventional bevel lock differentials in most designs is that relatively heavy mechanical wear occurs, especially in variants with friction discs. The blocking effect decreases with increasing mileage.
  • a disconnect clutch is also required to be fitted with an anti-lock brake system or with a system for preventing vehicle instability (so-called ESP). make compatible, otherwise the reaction between individual wheels affects the scheme negative.
  • Conventional barriers are relatively sensitive to tires with different rolling circumferences, for example because of different air pressure or different tread depth, because this can lead to differential speeds and may result in increased wear. Thus, for example, the driving speed and the route to be handled with emergency wheels severely limited.
  • a not insignificant effect is also in an increased understeer of the vehicle when cornering with low wheel slip, because in such driving situations is counteracted by the limited slip differential required per se.
  • the steering behavior of the vehicle can be noticeably worsened by this effect.
  • spur gear differential lifting devices are increasingly being used for the cited applications, which usually have defined slip angles of the intermeshing planet gears and of the sun gear.
  • FR 2 566 080 A describes such a Stirnraddifferenziagethebe with helical sun and planetary gears.
  • Such Stirnraddifferenzitigethebe have gears with oblique teeth.
  • defined angles of inclination of both the planets and the drive sun gears are provided. This results in axial Vernierungskraftkomponenten depending on the currently applied wheel torque. In a straight ahead of the vehicle and thus the same speeds of the coupled with the output shafts sun gears are based on each other.
  • This object is achieved with a Stirnraddifferenzialgetriebe with the features of the preamble of independent claim 1, characterized in that between parallel sun gears and / or between the sun gears and a surrounding housing each friction surfaces are arranged.
  • the invention relates to a Stirnraddifferenzialgetriebe with each helically toothed sun gears, planet gears and ring gear and a surrounding housing with bearings supported therein, wherein the parallel sun gears are each coupled to parallel output shafts. Between the parallel sun gears and / or between see the sun gears and the surrounding housing friction surfaces are arranged in each case. These friction surfaces can generate a targeted blocking effect by the axial forces occurring in the transmission, so that the inventive Stirnraddifferenzgegetriebe can form a limited slip differential with variable locking effect.
  • An embodiment of the Stirnraddifferenzgegethebes invention provides that in one revolution of the sun gears in a main direction of rotation, an axial Vernierungskraftkomponente is directed in each case to the outside, in the direction of the housing of the Stirnraddifferenziagethebes. Accordingly, in one revolution of the sun gears in the main rotation direction, the mutually remote first friction surfaces of the sun gears are pressed against the corresponding second friction surfaces on the inner sides of the housing, whereby the desired blocking effect is achieved.
  • the mutually facing third friction surfaces of the sun gears are pressed against each other in one rotation of the sun gears against the main direction of rotation.
  • the first, second and third friction surfaces may each have ring shapes and flat surfaces.
  • the friction surfaces may each be formed by plastic and / or elastomer-based materials and reinforced by metal particles and / or metal fibers.
  • Such a spur gear differential lifting unit can be provided in particular for use in the motor vehicle. It has each obliquely toothed sun gears, planetary gears and a helical gear and a ring gear receiving and surrounding the gears with helical teeth supported therein bearings. In this way, the sun gears are pressed in a straight ahead, which corresponds to the main direction of rotation, respectively to the outside. Especially at relatively high torques, this leads to a desired axial force component which, in conjunction with the friction linings, can produce the desired variable locking effect between the sun gears and the housing and thus between the two output shafts. Accordingly, in one of the main rotation direction opposite rotation of the sun gears, a mutually facing axial Vernierungskraftkomponente be formed.
  • Such a direction of rotation corresponds in the motor vehicle to a reverse gear.
  • this direction of rotation is to be expected with an increased tooth offset, which can provide in connection with the arranged on the sun gears and facing friction linings for a desired locking effect in overrun mode and / or when reversing the vehicle.

  • the Stirnraddif- ferentialgetriebe 10 has a radially encircling, helical Stirnz geddlingung 12, via which the Stirnraddifferenziagethebe 10 is driven, so that it can be set about a central axis of rotation in rotation.
  • the spur gear 12 is rigidly connected to two housing halves 14 and forms together with these a differential housing 16 in which a planetary gear is arranged, wherein the differential housing 16 forms the planetary carrier.
  • the differential housing 16 acts as a sum shaft of the planetary drive.
  • FIG. 2 shows the structure of the helical Stirnraddifferenziagethebes 10 with the rotatably mounted on the housing halves 14 of the differential housing 16 planetary gears 20. All planetary gears 20 each have a helical toothing with corresponding helical gears of the two parallel sun gears 22nd comb. The sun gears 22 are each connected in a rotationally fixed manner to the two output shafts 18.
