Description

The single motor gearshift of pure electric automobile electric control mechanical type automatic speed variator
Technical field
The utility model is related to a kind of single motors of the electric control mechanical type automatic speed variator especially suitable for pure electric automobile Gearshift.
Background technology
At present, electric control mechanical type automatic speed variator is widely used on pure electric automobile, electric control mechanical type automatic speed variator Pluck shelves, gear selecting and hang shelves action be by electric control system controls shift motor, and pass through gear shifting actuating mechanism realize.With tradition Automobile engine compares, and the driving motor of pure electric automobile can be with rotating, and thus, electric control mechanical type automatic speed variator is not required to Want reverse gear.At present, electric control mechanical type automatic speed variator more than pure electric automobile third gear, progress plucks needed for shift process Three shelves, gear selecting and extension shelves actions, at least need two motors to complete, one of motor is responsible for gear selecting, another motor is born Duty plucks shelves and hangs shelves, of high cost using double motor type or more electric motor types gearshift mode, complicated in mechanical structure.In shift process, Gear selecting need to be passed through and put into gear and just complete gear shift action, shift time is longer, and gear shift precision is low, on the other hand, shifts gears with single motor It compares, the consumption electric energy of double motor type or more electric motor types gearshift mode is also the shortcomings that cannot ignoring.
Invention content
The purpose of this utility model is that overcome existing for the electric control mechanical type automatic speed variator of current pure electric automobile Drawbacks described above proposes a kind of single motor gearshift of electric vehicle electric control mechanical type automatic speed variator, shortens gearshift to realize Time improves gear shift precision, simplifies gearshift mechanical structure, reduces cost.
The single motor gearshift of the utility model electric vehicle electric control mechanical type automatic speed variator, including a gearshift electricity The cylindrical roll body and three one end are fixed with shift lever, the other end is fixed with selector fork that machine and shift motor are drivingly connected Selector fork axis;Three axially distributed annular grooves are equipped on the cylindrical roll body, each annular groove is along cylinder The track 2/3 of the plane outspread drawing of roll body outer surface be the straight line vertical with cylindrical roll body axis, remaining be by two sections of arc phases The sigmoid curve that anti-camber line is formed;The distance at arc top to the arc bottom of two sections of camber lines is the 1/2 of the synchronizer stroke of speed changer; The curved section of adjacent annular groove is relatively rotated 120 degree of distributions by circumferencial direction respectively two-by-two;
Three selector fork axis, being arranged on case of transmission in sliding fit, every gearshift are dialled respectively at both ends Shift lever on fork shaft being plugged in an annular groove in sliding fit respectively.
The operation principle of the utility model gearshift is:
The mechanism is mounted on gear box of automobile, the gearshift described in the mechanism on every selector fork axis is dialled Fork is respectively on the synchronizer between each shifting gear in speed changer;When cylindrical roll body rotates, shift lever is recessed in annular It is moved axially under the driving of slot movement locus, and then selector fork axis and selector fork is driven to move axially.It is changed when one It is corresponding embedding with the selector fork on the selector fork axis when shift lever in gear shift fork axle is in the straightway of annular groove The synchronizer put is in non-state of putting into gear;When the shift lever on a selector fork axis is in the sigmoid curve section of annular groove During the arc top of side, which is pushed to engage by the synchronizer set corresponding with the selector fork on the selector fork axis It puts into gear state;When the shift lever is in the opposite side arc top of the sigmoid curve section of annular groove, synchronizer is then by opposite side shelves Position gear is pushed to engage state of putting into gear.At this point, since the selector fork on another two selector fork axis is in its annular groove Straightway in, the synchronizer set corresponding with the selector fork on two selector fork axis be in non-state of putting into gear.
The single motor gearshift of the utility model electric vehicle electric control mechanical type automatic speed variator has following significant Excellent technique effect:
1. the single motor gearshift of the utility model electric vehicle electric control mechanical type automatic speed variator, shift process without The gear selecting of traditional type is needed, shift motor drives the cylindrical roll body rotation equipped with annular groove that direct gear shift can be realized, can shorten Shift time improves gear shift precision.And greatly simplify the mechanical structure of power plant, it is ensured that the reliability of gear shifting action, It is easily installed, it is easy to maintain, reduce cost.
2. need to install electrical control actuator additional in the structure of Conventional parallel shaft type manual gearbox, slightly upgrading is Can, the escalation process period is short, and newly-increased investment is few, and production inheritance is good, greatly reduces cost.
3. shift control only needs to combine the rotation that shift schedule controls a motor, gearshift control system can be simplified System improves gear shift precision and gear shifting quality, makes its gearshift more rapidly, accurately, reliably.
Description of the drawings
Fig. 1 is a kind of axonometric schematic diagram of the single motor gearshift of electric vehicle electric control mechanical type automatic speed variator;
Fig. 2 is the partial structural diagram of cylindrical roll body 2 shown in Fig. 1;
Fig. 3 is plane outspread drawing of the annular groove along cylindrical roll body outer surface on cylindrical roll body 2 shown in Fig. 1;

Specific embodiment
The utility model is described in further detail below in conjunction with the embodiment that attached drawing provides.
Referring to figs. 1 to 4, a kind of single motor gearshift of electric vehicle electric control mechanical type automatic speed variator includes a gearshift Motor 1, with shift motor 1 be drivingly connected cylindrical roll body 2 and three one end are fixed with shift lever 4, the other end is fixed with and changes Keep off the selector fork axis 3 of shift fork 5;Axially distributed three annular grooves a, b, c are equipped on the cylindrical roll body 2, each Annular groove along the track 2/3 of the plane outspread drawing of 2 outer surface of cylindrical roll body for the straight line vertical with 2 axis of cylindrical roll body, its The remaining sigmoid curve to be made of two sections of arcs opposite camber line S1 and S2;The distance h at the arc top of two sections of camber lines S1 and S2 to arc bottom It is the 1/2 of the synchronizer stroke of speed changer;The curved section of adjacent annular groove relatively rotates 120 respectively by circumferencial direction two-by-two Degree distribution;
Three selector fork axis, being arranged on case of transmission in sliding fit, every gearshift are dialled respectively at both ends Shift lever on fork shaft being plugged in an annular groove in sliding fit respectively.When cylindrical roll body 2 rotates, it is plugged on annular Shift lever in groove is moved axially by annular groove driving, then selector fork axis and selector fork is driven to make axial move Dynamic, selector fork pushes synchronizer axial movement, realizes gearshift.
It is clear that according to the revealed gearshift of the present embodiment, it can be in the cylindrical roll according to automobile gears needs N annular groove on body 2 is set, and is correspondingly arranged n root selector fork axis, the curved section of each adjacent annular groove presses circumferencial direction The distribution of 360/n degree is relatively rotated respectively, you can is configured on the speed changer of various gear automobiles.The distressed structure made with this, Belong to the same design of the utility model, it should be in the protection domain of the utility model claims.
