Description
Technical field: the present invention relates to the automobile change-speed box, particularly a kind of Hybrid Vehicle change-speed box.
Background technology: hybrid vehicle has the anti-emission carburetor advantage of battery-driven car concurrently because of it and the high-energy-density advantage of internal-combustion engines vehicle more and more receives publicity, and becomes one of new vehicle of competitively research and development.Comply with this requirement, the research and development of the single output speed changer of the dual input of parallel type hybrid dynamic car special use just become a kind of inevitable.The parallel type hybrid dynamic car has two power input sources, and promptly driving engine and motor require to realize three kinds of operating modes such as pure motorized motions, pure engine drive, motor and driving engine combination drive in operational process.
Summary of the invention: the present invention is in order to solve the problem of double dynamical input single action power output, a kind of Hybrid Vehicle change-speed box is provided, mainly comprise housing, back cover, loam cake, top cover, one, tween drive shaft, two, gear, synchro, described one link with engine crankshaft, two link with transmission shaft, tween drive shaft cogs and one, two cog and constitute the constant-mesh driving gear pairs, it is characterized in that: increase a motor power input media on the described tween drive shaft.This Hybrid Vehicle change-speed box belongs to mechanical transmission, be on traditional mechanical transmission basis, to keep one engine power input, increase the proprietary motor power input media of hybrid vehicle again in the tween drive shaft rear end and form double dynamical input, both power can adapt to the desired various operating modes of hybrid electric vehicle complete vehicle well by two output unit outputs of traditional change-speed box.
When pure motorized motions, this reaches tween drive shaft to the constant-mesh driving gear pair to motor through the drive bevel gear on the motor power input shaft and the driven wheel of differential on the tween drive shaft, and the gear pair on tween drive shaft and two or reaches power two and the output bead output on two again.At this moment, the power-transfer clutch between driving engine and the change-speed box is in released state.
When pure engine drive, power reaches tween drive shaft through one with tween drive shaft constant-mesh driving gear pair by driving engine, again through tween drive shaft on two gear pair or directly power is reached two and output bead on two and exports.At this moment, motor does not have takeoff output by motor controller controls.
When motor and driving engine combination drive, power reaches two outputs through the power streamline of above-mentioned two kinds of operating modes with power respectively.At this moment, motor power and rotating speed be by motor controller controls, coordinates to guarantee respectively the power and the rotating speed that input to transmission countershaft or one through driving engine and motor.
Description of drawings: Fig. 1 is structural representation of the present invention.
The specific embodiment: as shown in Figure 1, this Hybrid Vehicle change-speed box mainly comprises housing 3, back cover 26, loam cake 34, top cover 35, one spool 4, tween drive shaft 5, two spools 24, gear and motor power input media.Its middle gear 6,7,8,9,10,11,12 is positioned on the tween drive shaft 5; Gear 14,15,17,18,20,22 skies are enclosed within on two 24; Synchro 13,16,19 is positioned on two.This change-speed box has four axles, and one 4 bent axle by power-transfer clutch 2 and driving engine 1 links, two 24 and two output beads 25 link, tween drive shaft 5 cogs and one 4, the two 24 formation constant-mesh driving gear pairs that cog; The motor power input media is positioned at the rear end of tween drive shaft 5, and the motor power input media comprises motor power input shaft 27 and driving gear pair.Wherein motor power input shaft 27 links with motor output bead, driving gear pair constitutes the constant-mesh driving gear pair by the driven wheel of differential 28 on drive bevel gear on the motor power input shaft 27 29 and the tween drive shaft 5, drive bevel gear 29 and motor power input shaft 27 one, and with the crossed-axes angle of driven wheel of differential 28 be 90.Reverse gearwheel shift sleeve 21, driving gear speedometer 23 also are installed on two 24, and the outside is two output beads 25.Top cover 35 is the AMT shift control system, and its gearshift has adopted the form of synchro in conjunction with AMT.The single output speed changer of the dual input of this Hybrid Vehicle change-speed box is to keep one engine power input on traditional mechanical transmission basis, increase a motor power input media again in the tween drive shaft rear end and form double dynamical input, certainly this motor power input media also can be increased in middle part or other positions of tween drive shaft, and both power are by two output unit outputs of traditional change-speed box.
Be illustrated in figure 1 as Neutral Position.Its principle of work of this Hybrid Vehicle change-speed box is as follows:
Pure motor-driven: the power of motor 32 is through motor transmission shaft 31 and motor power input flange 30, again through drive bevel gear on the motor power input shaft 27 29 and driven wheel of differential 28 engagements on the tween drive shaft 5 power is reached tween drive shaft 5 and on each grade gear, at this moment, because each grade gear on two 24 is that sky is enclosed within on two 24, so two 24 are not driven.After relevant ECU in the car load control will select, shift signal reaches AMT maneuvering system 35, the AMT maneuvering system can drive the shift fork action that selector gear in the loam cake 34 drives corresponding gear automatically, and gear shift is selected in realization.With the second gear is example, and second speed gear 18 directions of the sliding gear collar in the synchro 19 on two move, second speed gear 18 on two 24 and two 24 are combined as a whole, thereby drive two 24 rotations, and with power through two output beads 25 outputs.In the gearshift procedure, the AMT maneuvering system can be separated power-transfer clutch 2 automatically, and the disconnection driving engine is connected with change speed gear box, guarantees that gear shift is smooth.
Pure engine drive: the power of driving engine 1 through one 4 with tween drive shaft 5 on constant mesh gear reach tween drive shaft 5 and on each grade gear, at this moment and since two 24 on each grade gear be that sky is enclosed within on two, so two are not driven.After relevant ECU in the car load control will select, shift signal reaches AMT maneuvering system 35, the AMT maneuvering system can drive the shift fork action that selector gear in the loam cake 34 drives corresponding gear automatically, and gear shift is selected in realization.With the second gear is example, and second speed gear 18 directions of the sliding gear collar in the synchro 19 on two move, second speed gear 18 on two and two 24 are combined as a whole, thereby drive two 24 rotations, and with power through two output beads 25 outputs.At this moment, motor does not have takeoff output by electric machine controller 33 controls.
Motor and driving engine combination drive: the power of motor 32 is through motor transmission shaft 31 and motor power input flange 30, again through 28 engagements of the drive bevel gear on the motor power input shaft 27 and the driven wheel of differential on the tween drive shaft power is reached tween drive shaft 5 and on each grade gear, simultaneously, the power of driving engine 1 through one 4 with tween drive shaft 5 on gear reach tween drive shaft 5 and on each grade gear, power reaches two 24 outputs through the power streamline of above-mentioned two kinds of operating modes with power respectively.At this moment, motor power and rotating speed be by electric machine controller 33 control, coordinates to guarantee respectively the power and the rotating speed that input to transmission countershaft or one through driving engine and motor.
