Publication No. CN102808936B discloses a kind of " mechanical automatic gearbox gear-selecting and shifting executing mechanism ", and which passes through oil The cooperation of cylinder and piston is realized selecting gear shift, but piston and oil cylinder necessarily design the design of hydraulic circuit, increase cost and volume.
Publication No. CN102072312A discloses a kind of " gear-shifting actuating mechanism of automobile transmission ", and which is driven by motor and is subtracted Fast gear movement and then cylindrical cam motion is driven, but the structure driven noise of reduction gearing is big, gear centre is away from being difficult to adjust It is whole;Cylindrical cam causes executing agency's overall volume to become big.
The content of the invention
The technical problem to be solved is, for the above-mentioned deficiency of prior art, proposes that a kind of noise is little, suitable With scope is wide, the accurate automotive gear shifter executing agency of gear shift.
The present invention solves its technical problem, and the technical scheme of employing is to propose a kind of automotive gear shifter executing agency, its bag Include:
Motor;
Synchronous belt drive mechanism;The synchronous belt drive mechanism includes the first synchronizing wheel, the second synchronizing wheel and Timing Belt, Second synchronizing wheel is with diameter greater than the first synchronous wheel diameter;First synchronizing wheel is connected with motor transmission shaft;
Screw mandrel;The screw mandrel is connected with the second synchronizing wheel;
Nut;It is sheathed on screw mandrel, can rotates and transverse shifting with screw mandrel;
Flexible axle attachment structure, is arranged on nut.
Further, also including box body, the motor, screw mandrel and flexible axle attachment structure are respectively positioned in box body;The motor It is arranged at below box body;The screw mandrel is coaxially disposed with flexible axle attachment structure.
Further, also including lower stator, the lower stator include rounded main part and from main part to The two triangle end of outer extension;The connecting hole for being fixedly connected with box body is provided with the two triangle end.
Further, the fixed disk with diameter greater than the second synchronizing wheel is provided with the outside of second synchronizing wheel;The fixation Disk is formed with multiple through holes;Also include wiring board, be arranged at the infrared facility at wiring board two ends;The infrared facility transmitting Infrared ray may pass through the through hole.
Further, the flexible axle attachment structure includes connector, connecting rod;Fixation is offered in the middle part of the connector Hole, connector pass through fixing hole and stretch in nut so that connector is fixedly connected with nut;Connection head-tail arranges grafting Sleeve, the connecting rod are plugged in the grafting sleeve;Sawtooth portion is provided with the outside of the grafting sleeve.
The present invention is by driving synchronous belt drive mechanism operating by motor, and then drives screw mandrel motion, screw mandrel to drive screw rod Transverse movement, nut drive the motion of flexible axle attachment structure and then change gear;Above-mentioned drive mechanism is not using gear-driven Mode so that noise during overall operation is less.Synchronous belt drive mechanism is applied in selector executing agency, gear is compared Also there is the kind of drive more flexible centre-to-centre spacing and less volume to take.
Description of the drawings
Fig. 1 is the dimensional structure diagram at a visual angle of the present invention;
Fig. 2 is the dimensional structure diagram at another visual angle of the invention.
Specific embodiment
The following is the specific embodiment of the present invention and combine accompanying drawing, technical scheme is further described, But the present invention is not limited to these embodiments.
Fig. 1, Fig. 2 is refer to, automotive gear shifter executing agency of the present invention is by box body 100, motor 200, toothed belt transmission machine Structure 300, screw mandrel 400, nut 500 and flexible axle attachment structure 600 are constituted.
Box body 100 is substantially L-shaped, and motor 200 is arranged and L-shaped box body bottom, and screw mandrel 400 is same with flexible axle attachment structure 600 Axle is arranged on the upside of L-shaped box body.Synchronous belt drive mechanism 300 is arranged on the outside of box body 100, and nut 500 is sheathed on screw mandrel 400 On.
Synchronous belt drive mechanism 300 is made up of the first synchronous pulley 310, the second synchronous pulley 320 and Timing Belt 330. First synchronous pulley 310 is connected with the output shaft of motor 200, and the second synchronous pulley 320 is connected with screw mandrel 400.First Timing Belt 310 diameters are taken turns less than 320 diameter of the second synchronous pulley so that synchronous belt drive mechanism also functions to the effect slowed down.
Fixed disk 340 is provided with the outside of the second synchronous pulley 320, and fixed disk 340 is with diameter greater than the second synchronous pulley 320 Diameter.Multiple through holes 341 are evenly arranged with 340 excircle of fixed disk.Also include wiring board 344, be arranged at wiring board two The infrared facility 343 at end;The infrared ray 342 of the infrared facility transmitting may pass through the through hole 341.When fixed disk 340 During rotation, the screw rod transmission number of turns is calculated by the break-make number of times of infrared ray 342.
Also be arranged with lower stator 311 on first synchronous pulley 310, lower stator 311 include rounded main part with And the two triangle end stretched out by main part;It is provided with the two triangle end for being fixedly connected with box body Connecting hole.Using lower stator 311 fix by the way of can save space but also with good fixed effect.
In the present invention, after motor obtains control instruction, motor comes into operation, and motor drives synchronous belt drive mechanism fortune Dynamic, the action transmission of motor accurately can be played decelerating effect by synchronous belt drive mechanism again, at the same drive noise it is little, Centre-to-centre spacing determines flexible.Transmission is transferred to screw mandrel by synchronous belt drive mechanism, drives nut to move left and right further when screw mandrel is rotated Pull the movement of flexible axle attachment structure to change gear.
