The speed changing gear mechanism is a four-shift speed changing gear mechanism which is composed of an input shaft, an input shaft gear, a middle shaft, a middle shaft constant meshing gear, a middle shaft fourth shift gear, a middle shaft second shift gear, a middle shaft first shift gear, an output shaft, an output shaft fourth shift gear, an output shaft second shift gear, an output shaft first shift gear, a second shift synchronizer and a third-fourth gear synchronizer. The novel AMT is scientific and reasonable in structural design, has the advantages of small axial volume, small installation space occupied, agile operation, strong power and low energy consumption and can cover all steering work conditions of the coach and is more appropriate for the hybrid and pure electric motor coach.
Description
Technical field
The utility model belongs to the automotive transmission field, the special-purpose AMT speed changer of particularly a kind of novel hybrid and pure electric coach.
Background technique
The AMT speed changer had both had hydraulic automatic speed variator self-shifting advantage, had kept the gear-driven efficient height of former manual transmission, low, simple in structure, the easy strong point of making of cost again.Therefore, the AMT speed changer be used on hybrid power passenger car and the pure electric coach use comparatively extensive.But existing Bus Special AMT speed changer is five grades of speed changes mostly, i.e. four forward gearss and a reverse gear, and it exists speed changer structure complicated, and length is big, and the big problem that takes up room is installed.At present, according to the driving cycle characteristics of passenger vehicle, also more employing three-speed gearbox, i.e. three forward gearss, reverse gear is then realized by motor driving.But the operating mode scope that three-speed gearbox was fit to is less, causes and controls inconvenience, the energy consumption problem of higher.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, provides a kind of novel hybrid and pure electric coach special-purpose AMT speed changer, and it is little to have a volume, is fit to automobile running working condition, is easy to control advantage of low energy consumption.
The utility model solves its technical problem and takes following technological scheme to realize:
The special-purpose AMT speed changer of a kind of novel hybrid and pure electric coach; Comprise the mechanical transmission body; This mechanical transmission body is made up of housing, the change gear mechanism and the selector device that are installed in the housing; It is characterized in that: institute's change gear mechanism is the four-speed gear shift gear mechanism; This four-speed gear shift gear mechanism is made up of input shaft, input shaft gear, jack shaft, jack shaft constant mesh gear, jack shaft fourth gear, secondary gear of intermediate shaft, one grade of gear of jack shaft, output shaft, output shaft fourth gear, output shaft intermediate gear, one grade of gear of output shaft, a second gear synchronizer, three fourth gear synchronizers; Input shaft gear is installed on input shaft; Jack shaft constant mesh gear, jack shaft fourth gear, secondary gear of intermediate shaft, one grade of gear of jack shaft are installed on jack shaft; Output shaft fourth gear, output shaft intermediate gear, one grade of gear of output shaft are installed on the output shaft, three fourth gear synchronizers are installed between input shaft gear and output shaft fourth gear, a second gear synchronizer is installed between output shaft intermediate gear and one grade of gear of output shaft.
And said input shaft, output shaft and jack shaft all adopt tapered roller bearing to be installed on the housing.
The advantage and the good effect of the utility model are:
The utility model scientific structure design is reasonable, and transmission gear adopts the four-speed gear shift gear mechanism, and the four-speed gear shift gear mechanism does not comprise reverse gear; Reverse gear operation is driven by the outside drive motor of installing of speed changer fully, and it is little to have an axial volume, and it is little to take installing space; Flexible operation, power character is strong, and energy consumption is low; Can cover the advantage of the whole driving cycles of passenger vehicle, it is special-purpose to be fit to mixed power and pure electric coach more.
