Abstract
The invention discloses a transfer gear motor assembly which belongs to a control signal generator in an automobile gear switching system and aims at providing a high-reliable and high-automatic transfer gear motor assembly. The motor assembly comprises a motor, a reducer which is fixe on a gear box and is driven by the motor, and a potentiometer driving mechanism which is arranged in the gear box and is driven by the reducer. The potentiometer driving mechanism consists of a small gear (6) which is fixe on the output shaft of the reducer (3), a large gear (9) which is meshed with the small gear (6) by a medium gear (7), and a potentiometer (10) which rotates along the large gear; therefore, the invention is characterized by accurate action, high automatic degree, low power and large output torque, and the like, and is mainly used for the switching between the two operation modes of manual shift and infinitely variable speeds.
Description
Technical field: the present invention relates to a kind of control signal generating means, relate in particular to a kind of control signal generating means that is used for automobile gear switched system.
Background technique: at present, medium-to-high grade car all has manual shift and stepless change two big functions mostly, when needs switch mutually to manual shift pattern and stepless shift mode generally all is to realize by manual mode, troublesome poeration but also have the hidden danger that causes automobile to damage because of act of operation is not in place not only, reliability is not high.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the present invention aims to provide a kind of good reliability, transfer case motor assembly that automaticity is high, and the present invention is switched actuator with gear switched system controller and gear and cooperated the mutual switching that just can realize manual shift and stepless change two big operator schemes smoothly.
To achieve these goals, the present invention by the following technical solutions: it comprises motor, be fixed on the gear-box by the retarder of this motor driven, be arranged on the potentiometer driving mechanism that is driven by described retarder in this gear-box; Described potentiometer driving mechanism constitutes by being fixed on small gear on the reducer output shaft, the gearwheel by intermediate gear and pinion, the potentiometer that rotates synchronously with this gearwheel.
The rotor of motor is by the high-speed double electromagnet braking that is fixed on this motor.
Compared with the prior art, therefore the present invention has characteristics such as action is accurate, automaticity is high, and power is little, output torque is big owing to the principle according to closed loop control has adopted technique scheme; In addition, owing to adopted the electromagnet braking device, therefore also has the high advantage of reliability.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the plan view of Fig. 1.
Among the figure: electromagnet 1 motor 2 retarders 3 gear box covers 4 gear housings 5 small gears 6 intermediate gears 7 gear shafts 8 gearwheels 9 potentiometers 10 Large Gear Shaft During 11 decided by the people position supports 12 positioning holes 13
Embodiment: the invention will be further described below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: gear box cover 4 constitutes gear-box by screw on gear housing 5, motor 2 is fixed on the gear box cover 4 by fixedly connected with it retarder 3, the free end of retarder 3 output shafts stretch in the described gear-box and by Bearing Installation on gear housing 5; The two ends of gear shaft 8 are separately fixed on gear box cover 4 and the gear housing 5, the two ends of Large Gear Shaft During 11 respectively by Bearing Installation on gear box cover 4 and gear housing 5, be fixed on small gear 6 and intermediate gear 7 engagements that are installed in by axle sleeve on the gear shaft 8 on retarder 3 output shafts, be fixed on gearwheel 9 and this intermediate gear engagement on the Large Gear Shaft During 11; Potentiometer 10 is fixed on the Large Gear Shaft During 11.In order to guarantee that Large Gear Shaft During 11 can accurately stop when rotating to preposition, be fixed with electromagnet 1 at the other end of motor, the rotor of motor 2 can overcome inertia and realize braking rapidly under the effect of this electromagnet 1; In order to prevent potentiometer 10 when forwarding preposition to and deflect, two locating studs of locating support 12 are inserted in the axis hole of Large Gear Shaft During 11 respectively and in the positioning hole 13 of gear box cover 4; The effect of locating support 12 is to limit potentiometer 10 start angles and dustproof.
Working principle: the potentiometer 10 that rotates synchronously with Large Gear Shaft During 11 changes the angular displacement analogue signal into electrical signal linearly and feeds back to gear switched system controller, the rotation of motor 2 is revised, controlled to this controller in real time according to the electrical signal of feedback, thereby realize gear is switched the control of actuator by the control to Large Gear Shaft During 11 angle of swing; When Large Gear Shaft During 11 rotated to preposition, described gear switched system controller sent instruction, and motor 2 stops operating under the effect of electromagnet 1, finished a period run and realized automatically mutually switching of manual shift pattern and stepless shift mode.
