Abstract
The utility model discloses an electric control transfer case device of an automobile. The electric control transfer case device comprises a transfer case assembly, a shift motor and a transfer case electric control unit (ECU); the shift motor is installed on the transfer case assembly; a signal output end of the transfer case ECU is connected with a signal input end of the shift motor through a guide line. The electric control transfer case device is characterized in that a knob-type transfer case shift switch is installed near a central tunnel control box assembly of an operator cabin; the transfer case shift switch comprises three gears, namely, 2 wheel drive (WD) gear, 4 high (H) gear and 4 low (L) gear; the three gears are respectively connected with three gear signal ends of the transfer case ECU through guide lines; and the switching between 2WD and 4WD of the transfer case assembly can be realized under the control of electric signals output by the transfer case ECU only through turning the transfer case shift switch into a required gear during the operation of a driver. The electric control transfer case device has the advantages of capability of realizing the switching between the 2WD and the 4WD of the transfer case assembly by controlling knobs of the transfer case switch during driving, no need of switching at a half-way stop, saving of one operating lever, saving of operator cabin space and simplicity and convenience for operation.
Description
Technical field
The utility model relates to automobile equipment, especially relates to the automobile electrically-controlled power divider device of a kind of energy by the convenient realization vehicle two of motor switch, 4 wheel driven handoff functionality.
Background technology
As everyone knows, when automobile travels, can adopt four wheel drive in order to overcome the tyre skidding chaufeur usually on bad road surfaces such as abrupt slope, mud, sand ground, ice cunning.At present, the switching of most of vehicle 4 wheel driven realizes by mechanical control that all except that change-speed box had a declutch shift lever, part-time case also had a declutch shift lever.It mainly contains following shortcoming: 1, must stop could realize two driving, the switching of 4 wheel driven, operation inconvenience; 2, two one control levers are arranged in the operator's compartment, not only not attractive in appearance but also accounted for than large space, be not easy to operation; 3, body platform need be opened the vertical pole position that bigger opening is just got out of the way part-time case behaviour, is unfavorable for sound insulation.
Summary of the invention
The purpose of this utility model is to provide a kind of only the need under steam just can realize two driving, the switching of 4 wheel driven, not need stop off to switch, save an one control lever, saving cab space, automobile electrically-controlled power divider device simple to operation by the knob of control part-time case switch.
The purpose of this utility model is achieved in that
A kind of automobile electrically-controlled power divider device, comprise transfer case assembly, gear shift motor and part-time case ECU(electronic control unit), the gear shift motor is installed on the transfer case assembly, the signal output part of part-time case ECU links to each other by the signal input part of lead with the gear shift motor, feature is: at the other part-time case Gear-shift switch that knob is installed of the central tunnel control box assembly of operator's compartment, the part-time case Gear-shift switch has 2WD gear, 4H gear and three gears of 4L gear, and three gears link to each other with three gear signal ends of part-time case ECU respectively by lead.
The utility model is the part-time case Gear-shift switch that knob is installed in the other place of being convenient to driver's operation of the central tunnel control box assembly of operator's compartment, chaufeur only needed the part-time case Gear-shift switch is threaded to required gear in when operation, can control by part-time case ECU output electronic signal and realize that two of transfer case assembly drives with 4 wheel driven and switch.The part-time case principle of work: 1, when the part-time case Gear-shift switch is threaded to the 2WD shelves, wheel-drive mode travels after the vehicle; 2, when the part-time case Gear-shift switch was threaded to the 4H gear, vehicle was run at high speed with 4 wheel driven; 3, when the part-time case Gear-shift switch is threaded to the 4L gear, part-time case ECU 5 outputs signal to the gear shift motor, is keeping under the situation that 4 wheel driven gear shift tooth cover engages under the 4H state, and gear shift motor driven deceleration shifting shift fork carries out gear shift, to reach the effect that changes transmitting ratio, vehicle is with the 4 wheel driven low speed driving.Therefore, the utlity model has under steam and only to need just can realize two driving, the switching of 4 wheel driven, not need stop off to switch, save an one control lever, saving cab space, advantage simple to operation by the knob of control part-time case switch.
Description of drawings
