Definitions

  • This invention relates to a drive device for a motor vehicle according to the preamble of claim 1.
  • the transmission can be a manual transmission or an automatic transmission.
  • the control device for the engine can be an electronic control unit for the transmission and engine, but also a control unit provided for the engine alone - Motronik - or also a so-called E-gas device, via which e.g. B. depending on the position of the accelerator pedal, the injection pump or the position of the throttle valve is controlled. It can also be a control device with the aid of which only the ignition timing of the engine is adjusted.
  • the gearboxes are designed in such a way that they are suitable for certain drive motors, the delimitation or assignment being made via the maximum permissible gearbox input torque or the engine torque, as in the overviews 85/1 ZF-Ecomat® and 85/1 ZF manual gearbox can be seen.
  • Gearbox output shaft in certain gear ratios via an engine intervention it is possible to optimize the design of the gearbox elements without this meaningful performance requirements for the drive device are not met.
  • gearbox elements Especially in the area of reverse gears, but also e.g. B. in first gear there are torques that are not necessary if these gears are used sensibly.
  • the design of the gear elements must, however, take into account the maximum possible torques, because when starting from a stand on the mountain and perhaps with a trailer, the occurrence of these torques cannot be ruled out.
  • By limiting the engine power in these gears it is possible to safely dimension gear elements, whereby the dimensioning of these parts leads to a more harmonious insertion into the overall gear.
  • the transmission ratio in which a motor intervention to limit the torque on the transmission output shaft is to be detected, can be detected in a simple manner via an electrical switch on or in the transmission or on the shift linkage.
  • an electrical switch on or in the transmission or on the shift linkage In automatic transmissions, it is also possible to use the selector switch for this, so that the implementation is associated with very little effort, because in particular the variously possible control devices for the motor are already available for other reasons.
  • the power limitation is to be in connection with the R-gear, the R-gear switch for the reverse gear lighting in all vehicles can also be used for signal generation.
  • Fig. 1 is a block diagram of the drive device
  • 2 shows an automatic transmission in a schematic representation
  • 3 shows a table of the clutches and brakes engaged in the individual gears
  • Fig. 5 shows a characteristic with engine control.
  • the drive motor 1 is mechanically connected to at least one drive axle 3 of a motor vehicle via an automatic or manual transmission 2.
  • the drive motor can be in any design customary for motor vehicles, e.g. B. as a suction motor with an adjusting device for the throttle valve 11 and a known ignition device with ignition timing 13, or z. B. also as a diesel engine with an adjusting device for the injection pump 12.
  • the transmission 2 can, for. B. as a manual transmission with countershaft as well as an automatic transmission 20, z. B. with planetary gears, but also as a continuously variable transmission. All other gear combinations used for motor vehicles are possible if they only have one device 22, via which a predetermined translation, for. B. a cleared passage is recognizable.
  • the transmission output shaft 21 is connected to at least one vehicle drive axle 3.
  • the drive power of the drive motor is z. B. an automatic transmission 2, 20 to a differential 31 and via the semi-axles 32 to drive wheels 33.
  • a control device 4 for the drive motor 1 is connected via an electrical line 23 to a device for gear recognition 22, for example a switch, and via the electrical line 41 to a control device for the throttle valve 11 or injection pump 12 and via the electrical line 42, e.g. B. connected to the ignition timing adjusting device 13.
  • the drive takes place either via the transmission input shaft 203, the torque converter 201 and the inner shaft 204 for clutch A and B or also via the damper 206 and the inner shaft 205 for clutch E.
  • the transmission can be made more compact overall, because in addition to the transmission elements mentioned, including the transmission output shaft 21, 210, the design can be smaller, weaker or narrower. If the torque for the transmission output shaft 21, 210, which results from the maximum engine torque in the first forward gear, is used as the basis for the engine torque limitation in the R gear, this limitation does not result in any practical restrictions, because at least with a normal motor vehicle a significantly higher output in the R-gear compared to the first gear makes no sense at all. With the limitation of the engine torque as a function of a predetermined transmission ratio and a defined torque in the transmission output shaft 21, 210 it is also possible to use stronger motors in connection with gearboxes with a weaker design.
  • the drive device acts as follows: via the gear detection 22 on the transmission 2 or the selector switch 5, the control device 4 detects the transmission ratio in the transmission 2 via lines 23 or 51, e.g. B. the switched reverse gear. While in all other ratios - gears - according to FIG. 4 and characteristic curve K 1, with the adjustment of the throttle lever ⁇ G the filling "of the engine also leads to a higher filling by continuously adjusting the throttle valve"önDK or increasing the injection quantity EM, 5 and characteristic curve K 2, the charge is limited in the shifted reverse gear, so that the further throttle lever adjustment does not lead to a higher charge and thus also to a power limitation.
  • a torque sensor 7 may be arranged, which is connected via a line 71 to the control device 4. If the engine intervention to limit the engine power is to take place in reverse gear, the switch for the reverse gear lighting, which is present in every vehicle, can also be used in a simple manner for the transmission detection - gear detection - in the transmission. For the engine intervention to limit the power, the ignition timing adjusting device 13 can also be used in addition or for relatively short times, as is known. Reference numerals

Abstract

Un système de transmission est utilisé avec des véhicules à moteur ayant un moteur d'entraînement (1), une boîte de vitesses (2), au moins un axe de transmission (3) et un dispositif de commande (4) du moteur d'entraînement (1) qui commande le remplissage par l'intermédiaire d'une soupape d'étranglement (11) ou d'une pompe d'injection (12), et/ou qui influence le moment d'allumage par un dispositif de réglage (13). Selon un rapport prédéterminé de la boîte de vitesses (2), la puissance du moteur d'entraînement (1) est limitée de telle sorte par un engrènement du moteur qu'un couple défini de l'arbre de sortie (21, 210) de la boîte de vitesses n'est pas dépassé. Il devient ainsi possible de prévoir des éléments plus faibles de la boîte de vitesses subordonnés à un rapport prédéterminé, tels qu'embrayages, freins (B, C', D), roues dentées (208, 213, 209) et arbres (210, 214, 212, 207) et d'obtenir des boîtes de vitesses plus compactes.
