Abstract
The utility model relates to a two-gear gearbox assembly which comprises a shell, a driving gear shaft, an output gear shaft and a driven gear shaft, wherein the driving gear shaft, the output gear shaft and the driven gear shaft are arranged in the shell. A control mechanism is additionally arranged on the shell; an electric shift mechanism and an electric parking mechanism are additionally arranged in the shell, wherein the electric parking mechanism is composed of a parking gear shift fork, a parking gear driving gear and a parking gear shaft; a low-speed-gear gear, a synchronizer and a high-speed-gear gear are arranged on the driven gear shaft in sequence. The two-gear gearbox assembly is simple in structure, small in size, light in weight, easy to manufacture and low in cost; the control mechanism controls a motor of the electric shift mechanism and the electric parking mechanism to achieve automatic parking and gear shifting of vehicles, operation is easy, parking and shifting are performed synchronously, and vehicle driving is good in continuity and reliability, so that driving comfortability and stability of vehicle driving are improved; the two-gear gearbox assembly is used for new energy vehicles, so that the self weight of the vehicles is effectively reduced, the carrying capacity of the vehicles is improved, and the economic benefits of the vehicles are increased.
Description
Technical field
The utility model relates to a kind of gearbox, is specifically related to a kind of two grades of transmission assemblies.
Background technique
Two grades of gearboxes of existing new energy, just simply be transplanted to the gearshift mechanism of manual transmission on new energy vehicle, and without automatic gearshift, the no-clutch device.This two grades of gearboxes power when driving can't disconnect, and can not utilize the synchronizer principle to carry out synchronized shifting, there is no the Parking shelves, can only adopt the gearshift of stopping, and the shift process complexity operates discontinuously, and driving comfortability is poor.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, and a kind of simple in structure, processing ease is provided, driving gear shift continuity and two grades of good transmission assemblies of driving comfortability.
Two grades of transmission assemblies of the present utility model, comprise housing and be located at driving gear shaft, output gear shaft and the driven gear shaft in housing, it is characterized in that: on described housing, have additional control mechanism; Have additional electric shift mechanism and electric parking mechanism in described housing; Described electric parking mechanism consists of Parking shelves shift fork, Parking shelves driving gear and Parking shelves axle; Described driven gear shaft is provided with bottom gear gear and top gear gear, between bottom gear gear and top gear gear, is provided with synchronizer; Driving gear shaft, driven gear shaft, output gear shaft are successively by the intermeshing transmission of gear pair on it.
The utility model is simple in structure, volume is little, lightweight, expense easy to manufacture is low; Control mechanism is realized automatic parking and the transforming gear of vehicle by the motor of controlling electric shift mechanism and electric parking mechanism, simple to operate, parking gear shifting synchronously carries out, and Vehicle Driving Cycle continuity and good reliability have improved the stability of driving comfortability and Vehicle Driving Cycle; For new energy vehicle, effectively reduce the deadweight of vehicle, improved carrying capacity and the economic benefit of vehicle.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The structural representation that Fig. 2 is driven gear shaft.
In figure: 1, Parking shelves shift fork, 2, electric shift mechanism, 3, Parking shelves axle, 4, housing, 5, output gear shaft, 6, Parking shelves driving gear, 7, control mechanism, 8, driving gear shaft, 9, driven gear shaft, 10, reverse shift fork, 11, synchronizer, 12, bottom gear gear, 13, the top gear gear.
Embodiment
Two grades of transmission assemblies of the present utility model, comprise housing 4 and be located at driving gear shaft 8, output gear shaft 5 and the driven gear shaft 9 in housing 4.Have additional control mechanism 7 on housing 4; The electric parking mechanism that has additional electric shift mechanism 2 in housing 4 and formed by Parking shelves shift fork 1, Parking shelves driving gear 6 and Parking shelves axle 3.Driven gear shaft 9 is provided with bottom gear gear 12 and top gear gear 13, between bottom gear gear 12 and top gear gear 13, is provided with synchronizer 11.Driving gear shaft 8, driven gear shaft 9, output gear shaft 5 are successively by the intermeshing transmission of gear pair on it.
Two grades of transmission assemblies of the present utility model are work like this:
In Vehicle Driving Cycle, while needing gearshift, control mechanism 7, according to travelling speed, by controlling the motor operation of electric shift mechanism 2 and electric parking gear mechanism, under the effect of synchronizer 10, realizes that parking gear shifting synchronously carries out, and completes the switching of gear automatically.
