摘要： PROBLEM TO BE SOLVED: To provide the control technology of a hybrid vehicle for suppressing an internal combustion engine from operating in a driving condition with a high fuel consumption rate by achieving a request driving force by making an internal combustion engine and an electric motor cooperatively operate. SOLUTION: The hybrid vehicle 1 is provided with: a dual clutch type transmission 10 as a multi-level transmission equipped with an internal combustion engine 5 and an electric motor 50 as a motor for shifting an engine output from the internal combustion engine 5 by any of a plurality of shift stages 31 to 49, and for transmitting it to a drive wheel 88; and an HVECU 100 as a control means for controlling the operation of the internal combustion engine 5 and the electric motor 50 according to a request drive force. When the driving condition of the internal combustion engine 5 is in a region at the low load side of a light load restriction line preliminarily set at the low load side of an optimal fuel consumption line, the HVECU 100 achieves a request driving force by making the internal combustion engine 5 and the electric motor 50 cooperatively operate so that the engine output can be increased.

摘要： PURPOSE:To form a geared transmission into a multistage shift as well as to shorten the extent of length in the axial direction of a transmission in the base where a backward speed is constituted into a normally engaged type gear train. CONSTITUTION:A function of first gear speed and backward shift gear trains is imparted to a first shift gear train (second drive gear 14b, second counter gear 16b) among plural shift gear trains constituting each of shift speeds, while another function of first, second and 5-shift gear trains are imparted to a second shift gear train (fifth drive gear 14c, fourth driven gear 15d), through which common use of plural shift gear trains is promoted, thus the extent of length in the axial direction of a transmission is shortened.

摘要： PURPOSE:To prevent gear sound at the time of engagement between an idler gear and a driving gear by providing a connecting means for connecting a brake means to a reverse-shift arm so as to be interlocked with a reverse idler gear. CONSTITUTION:When a shift lever is reverse-shift operated, a fork shaft slides to the left, and a reverse-shift arm 24 is intermittently oscillated in the clockwise direction. While the arm 24 is oscillated, the fork shaft 27a and the shift fork 27b of a connecting means 27 are shifted integrally to the left so as to slide the sleeve 26b of a brake means 26. The rotation of an input shaft 12 is regulated through a driven gear 25 and a driving gear 29 so as to stop the shaft 12, and at the same time, a reverse idler gear 23 is slided to the left so as to be engaged with a reverse driving gear 21 and a reverse driven gear in the stop state. As a result, the generation of gear sound at the time of reverse shift is prevented as well as reverse shift can be performed smoothly.

摘要： PURPOSE:To prevent a taper cone from making slide contact with a first synchronizer ring and a coupling member and to prevent lowering of durability by locating a spring member between a clutch hub and a coupling member. CONSTITUTION:During reverse shift operation, a hub sleeve 12 is slid leftward and by pushing the shoulder part of the engaging claw of a second key spring 18 by the protrusion part of the hub sleeve 12 along with the leftward slide of the hub sleeve, a second synchronizer 14 is pushed leftward. In this case, a spring 16e located between a clutch hub 11 and a coupling ring 16 constantly energizes the coupling ring 16 axially toward one side of the hub sleeve 12 by means of a force higher than frictional resistance. Thereby, at a reverse shift completion state, the energizing force of the spring 16e is exerted as a force against a traction force from a load in the direction of the arrow mark of the hub sleeve 12. Slide contact of a taper cone 15 with a first synchronizer ring 13 and the coupling ring 16 is prevented from occurring, and durability is improved.

摘要： PURPOSE:To enable a condition of two-wheel-drive or four-wheel-drive to be obtained preventing a differential limiting device from being differentially actuated, by forming the third connection condition such that a side gear side division shaft connects with a differential case of the first differential gear. CONSTITUTION:A coupling sleeve 38 provides in its small contour part 38b an internal spline 38d which continually engages with an external spline 25a of the first division shaft 25 further engages with and disengages from an external spline 35b in a small contour part 35a of an outer case 35, and plural toothed parts 38e which engage with and disengage from plural toothed parts 21a provided in the right end of a differential case 21 of a center differential gear 20a. Said small contour part 35a constitutes the third connecting shaft. A sliding control operation of the coupling sleeve 38 selectively interrupts coupling action performed between four members of a right side gear 23 of the center differential gear 20a, differential case 21, mount case 31 and the outer case 35.
