Definitions

  • the utility model relates to the automotive industry, in particular to gearboxes for vehicles.
  • a double clutch gearbox and its shifting method are also known (see patent RU 2011108248, IPC: (2006.01) B60K17 / 00, F16H3 / 00, 2011).
  • This gearbox is closest to the claimed technical solution for the combination of essential features, taken as a prototype.
  • the objective of the claimed utility model is to reduce the mass of automatic transmission, its metal consumption, cost, increase reliability and manufacturability.
  • the technical result consists in reducing consumables, simplifying the manufacturing process, simplifying the design and, as a result, increasing reliability.
  • an automated 6-speed gearbox (automatic transmission) contains two clutches, with drives on two concentrically arranged primary shafts connected through gears of constant meshing, with two secondary shafts. They are equipped with freely rotating gears of even and odd gears and splined carriages connected to shafts, even and odd gears, respectively, providing communication with the intermediate shaft. The freely rotating gears of the secondary shafts are engaged with the fixed gears of the intermediate shaft, from which the rotation is transmitted to the differential of the wheelset.
  • electromagnetic braking clutches are installed on the two secondary and intermediate shafts to reduce the angular speeds of rotation of gears and carriages, which with two clutches form a synchronization system for aligning rotation speeds couplings and gears for the purpose of shockless inclusion of splined carriages of a gear change.
  • the contact area of the slot on the carriage (clutch) and the splined crown of the gear engagement is larger in comparison with the traditional synchronizer, since it has a slope and an unlimited reasonable length and this increases wear resistance.
  • the work of an automated 6-speed gearbox is as follows, the rotation is transmitted from the internal combustion engine through a flywheel to an automatic transmission with two clutches, with drives on two concentrically located input shafts.
  • the input shafts are connected, through gears of constant engagement, with two secondary shafts.
  • Freely rotating gears of even and odd gears are installed on the secondary shafts, as well as splined carriages of even and odd gears are installed on them, respectively, providing communication through the gears of the intermediate shaft with the intermediate shaft.
  • the freely rotating gears of the secondary shafts are engaged, rigidly fixed, by the gears of the intermediate shaft, from which the rotation is transmitted to the differential of the wheelset.
  • Braking electromagnetic couplings are installed on the secondary shafts and the intermediate shaft, which with two clutches, through the computer control unit, being
  • the synchronizing device controls the angular speeds of rotation of the gears and carriages align the speed of rotation of the “gear-carriage” in order to shockless inclusion of spline carriages.
  • electromagnetic couplings mounted on the secondary and intermediate shafts can be used as a “box brake” by analogy with a “motor brake” in a non-wearing brake system (NTS), a wear-resistant brake system (ITS), or together with a motor brake to increase its effectiveness.
  • NTS non-wearing brake system
  • ITS wear-resistant brake system
  • each subsequent to the gear engaged in the clutch is activated clutch and braking the electrical circuit at idle.
  • the rotation speed of the carriage increases, aligning, to the speed of shockless engagement, to disengage the previous carriage, the clutch and the braking electromagnet are activated and the carriage is “twisted” out of engagement.
  • Each next gear “in descending” has a higher speed, to synchronize each next gear that is in the gearing, the clutch is deactivated and the brake clutches are activated on
  • the device of the gear shift on / off assembly consists of a spline carriage sleeve mounted on the secondary shaft and held by a segment key, which is held from rotation by a key.
  • the splined carriage freely moves along the splined carriage bushing in the axial direction along the shaft, and is engaged with the gear by means of a splined gear engagement ring.
  • this scheme will allow you to get a gearbox with two clutches, but with distinctive features, namely there is no gear shift synchronizer as such, there is only a one-sided carriage installed inside the gearbox with a synchronization system external to the outside.
  • the carriage is universal (single, TeVl-V6) for all gears and one-sided, i.e. works with one gear.
  • the gearbox is shorter in length by half - more compact, since the intermediate shaft is a transmitting force to the differential and has one gear per two gears of different gears.

Abstract

L'invention concerne des boîtes de changement de vitesses pour moyens de transport. L'invention concerne une boîte de changement de vitesses automatisée à 6 rapports comprenant deux embrayages avec des actionneurs et deux arbres primaires concentriques connectés par des pignons de connexion permanente avec deux arbres secondaires. Des pignons de vitesses paires et impaires sont montés librement en rotation sur les arbres, ainsi que des coulisseaux crantés de vitesses paires et impaires, respectivement, connectés aux arbres. Les pignons en rotation libre des arbres secondaires sont couplés à des pignons fixes d'un arbre intermédiaire depuis lequel la rotation est transmise à un différentiel d'une paire de roues. Sur les arbres secondaires et sur l'arbre intermédiaire sont disposés des couplages de freinage électromagnétiques qui, avec les deux embrayages, forment un système de synchronisation afin d'égaliser les vitesse de de rotation des couplages et des pignons. Il est ainsi possible d'obtenir une structure compacte et simple.
