Abstract
The utility model discloses an automatic double-shift transmission for an electric vehicle. The automatic double-shift transmission comprises a controller, an input shaft and an output part, and further comprises two clutches and an intermediate shaft which is parallel to the input shaft; the two clutches both penetrate into the input shaft, one clutch is a high-speed clutch, and the other one is a low-speed clutch; and the outer end faces of the two clutches are respectively connected with an input shaft high-speed gear and an input shaft low-speed gear; an intermediate shaft high-speed gear and an intermediate shaft low-speed gear which are meshed with the input shaft high-speed gear and the input shaft low-speed gear are respectively arranged on the intermediate shaft; and an intermediate shaft gear which is connected with the output part is also arranged on the intermediate shaft. The automatic double-shift transmission is simple in structure, has a smaller size, a lighter weight and small shift change impact force, and can satisfy load requirements during climbing and speed requirements during traveling on the flat ground.
Description
Technical field
The utility model relates to a kind of automatic transmission, relates in particular to a kind of automatic transmission that is used in the electric motor car.
Background technique
Advantage enjoys liking of wage-earners because energy-conserving and environment-protective, price are low etc. in electric motor car, and electric motor car also was rapidly developed in recent years, had become one of main flow means of transportation.At present electric motor car generally comes the regulating electric machine rotating speed with the electric current of the different sizes of speed-regulating handle control controller output when control rate, motor drives wheel hub by speed changer and realizes motor speed control, though this mode configuration is simple; But in using engineering, need the gearshift of stopping, complex operation, and manual gearing transmission is larger because of the gearshift impact force, the poor ratio of speed between the gear can not be too large, so just cause electric motor car in the contradiction aspect speed and the load-carrying: when climbing, to need larger load-carrying, and when the level land, need larger speed.Although the someone has designed some automatic speed derailleur for electric vehicle at present, complex structure mostly, size, weight are larger.
Summary of the invention
For above-mentioned deficiency of the prior art, the utility model provides a kind of electric motor car two-shift automatic variable speed device, and is simple in structure, and size, weight are less, the little and speed requirement can satisfy load-carrying needs when climbing and level land time of gearshift impact force.
The technical solution of the utility model is: a kind of electric motor car two-shift automatic variable speed device, comprise controller, input shaft and output block, and also comprise two clutches and the jack shaft parallel with input shaft; Described two clutches all are located on the input shaft, and one of them clutch is the top gear clutch, and another is the bottom gear clutch; Described two clutches are connected with respectively input shaft high gear, input shaft low speed gear; Described jack shaft is provided with jack shaft high gear, the jack shaft low speed gear with input shaft high gear, the engagement of input shaft low speed gear; Also be provided with the countershaft-gear that is connected with output block on the described jack shaft.
As preferably, described two clutches all are connected with input shaft high gear, input shaft low speed gear respectively by screw.
As preferably, the input shaft between described two clutches is provided with a sleeve.
As preferably, described two clutches are magnetic clutch.
The beneficial effects of the utility model are: required parts are few, and are simple in structure, and size, weight are less; When the top gear clutch rotated with the input shaft high gear, electric motor car can obtain larger speed, was suitable for the level land and travelled; When the bottom gear clutch rotated with the input shaft low speed gear, the motor load-carrying was larger; Be suitable for climbing; Sleeve is separated two clutches, thereby reduces friction, and increases the service life; What use is that magnetic clutch carries out the speed switching, the frictional force of clutch can be carried out regulation and control by controller, when the clutch friction power that is in separation reduces, the clutch friction power that is in combination progressively increases, thereby reduce power interruption, so that the impact in gearshift procedure is less, the gear shift travelling comfort is high.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is use view of the present utility model.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of electric motor car two-shift automatic variable speed device as shown in Figure 1, comprises controller, input shaft 6 and output block 2, also comprises two clutches and the jack shaft parallel with input shaft 6; Described two clutches all are located on the input shaft 6, and one of them clutch is top gear clutch 5, and another is bottom gear clutch 9; Described two clutches are connected with respectively input shaft high gear 8, input shaft low speed gear 10; Be respectively equipped with jack shaft high gear 4, jack shaft low speed gear 1 with input shaft high gear 8,10 engagements of input shaft low speed gear on the described jack shaft; Also be provided with the countershaft-gear 3 that is connected with output block 2 on the described jack shaft.Described two clutches all are connected with input shaft high gear 8, input shaft low speed gear 10 respectively by screw 7.Input shaft 2 between described two clutches is provided with a sleeve 11.Described two clutches are magnetic clutch.
The structure of this device is very simple, function is very practical, controller is according to signal specific, such as road conditions, again by an action in two clutches of program control, when 5 work of top gear clutch, input shaft high gear 8 rotates with top gear clutch 5, this moment, the moment of torsion of motor input can be delivered on the input shaft high gear 8, thereby with torque drive to jack shaft high gear 4, driving countershaft-gear 3 rotates, drive output block 2 outputting powers by countershaft-gear 3, the driving electric car is done high-speed motion.When 9 work of bottom gear clutch, input shaft low speed gear 10 rotates with bottom gear clutch 9, this moment, the moment of torsion of motor input can be delivered on the input shaft low speed gear 10, thereby with torque drive to jack shaft low speed gear 1, driving countershaft-gear 3 rotates, drive output block 2 outputting powers by countershaft-gear 3, driving electric car low-speed motion, but can obtain larger load-carrying.
More than technological scheme that the utility model embodiment is provided be described in detail, used specific case herein the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation is only applicable to help to understand the utility model embodiment's principle; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on embodiment and application area, in sum, this description should not be construed as restriction of the present utility model.
