Description

Electronic minicar electromagnetism clutch gearbox

Technical field

The utility model relates to a kind of speed change gear, particularly a kind of electromagnetic clutch speed change gear that uses on electronic minicar.

Background technique

Present electronic minicar is generally regulated motor speed by controller control output current size when control rate, motor drives wheel hub by speed changer and realizes regulating control electric motor car speed, this mode configuration is simple, control is convenient, but in actual use, its requirement is different to electronic minicar to different road conditions; When cruising, require that motor speed is fast, gearbox output torque is little; When startup, climbing or heavy load, require that motor speed is slow, gearbox output torque is big; The deficiency of its existence is: the one, because speed changer can't change output torque under the constant condition of power of motor, therefore, when startup, climbing and heavy load motor being under the abnormal condition turns round, force motor in the work of poor efficiency district, make motor rotation blockage, heating, even stop operating, cause suddenly big electric current of storage battery and deep discharge, cause vitals such as motor, storage battery, controller to be impacted, shorten the life-span; The 2nd, grade ability is poor, accommodation is little, mileages of continuation is short.For this reason, many manufacturers and knowledgeable people have carried out the R and D of fruitful ground, but do not have rational product to emerge so far as yet.

Summary of the invention

In order to overcome the above-mentioned disadvantage that existing electronic minicar speed change exists, the purpose of this utility model provides a kind of simple and reasonable, the electronic minicar electromagnetism clutch gearbox that can export different moments of torsion according to different road conditions.

The technological scheme that its technical problem that solves the utility model adopts, it comprises casing, be arranged on input shaft and output shaft on the casing, input shaft is provided with small gear and driving gear, output shaft is provided with gearwheel and driven gear, casing is provided with jack shaft, jack shaft is provided with intermediate gear, small gear and gearwheel engagement, intermediate gear meshes with driving gear and driven gear respectively, described output shaft is provided with and the sliding clutch of gearwheel coupling and the reverse clutch that mates with driven gear, sliding clutch cooperates with output shaft by one-way element, reverse clutch cooperates with output shaft by spline tooth, and casing is provided with the electromagnetic clutch mechanism that cooperates with sliding clutch.

Described electromagnetic clutch mechanism comprises secured core, electromagnetic coil, clutch iron core, rocking arm, Returnning spring, secured core is fixed in the casing, electromagnetic coil is installed on the secured core; rocking arm is hinged on the casing; an end of rocking arm is clutch iron core and corresponding with secured core fixedly; the other end of rocking arm cooperates with the draw-in groove of sliding clutch, and Returnning spring is enclosed within on the output shaft between reverse clutch and the driven gear.

The end that described rocking arm cooperates with the sliding clutch draw-in groove is provided with roller.

After adopting said structure, the utility model control motor positive and inverse, two kinds of speed that output is set and moment of torsion, thus realize that electronic minicar can both stable operation in different road conditions; Make the reverse clutch combination by electromagnetic clutch mechanism, the output shaft counterrotating can realize reversing.So just can export different speed and moment of torsion according to actual needs, adapt to different road conditions, make storage battery big electric current and deep discharge can not occur, can effectively improve grade ability and mileages of continuation.

Embodiment

Shown in Figure 1, be the specific embodiments of the electronic minicar of the utility model with the electromagnetism clutch gearbox, it comprises casing 1, input shaft 14 and output shaft 15, input shaft 14 is arranged on the casing 1 by the bearing 13 of both sides, output shaft 15 is arranged on the casing 1 by the bearing 11 of both sides, input shaft 14 is provided with small gear 12 and driving gear 20, small gear 12 is provided with one-way element, driving gear 20 is fixed on the input shaft 14, output shaft 15 is provided with gearwheel 10 and driven gear 16, driven gear 16 is provided with one-way element, gearwheel 10 is actively set on the output shaft 15, casing 1 is provided with jack shaft 18, be fixed with intermediate gear 19 on the jack shaft 18, small gear 12 and gearwheel 10 engagements, intermediate gear 19 meshes with driving gear 20 and driven gear 16 respectively, described output shaft 15 is provided with and the sliding clutch 9 of gearwheel 10 couplings and the reverse clutch 3 that mates with driven gear 16, sliding clutch 9 cooperates with output shaft 15 by one-way element, reverse clutch 3 cooperates with output shaft 15 by spline tooth, and casing 1 is provided with the electromagnetic clutch mechanism that cooperates with sliding clutch 9.One-way element on the driven gear 16 is identical with the one-way element direction of sliding clutch 9, and the one-way element on the small gear 12 is opposite with the one-way element direction of sliding clutch 9.

Described electromagnetic clutch mechanism comprises secured core 7, electromagnetic coil 8, clutch iron core 6, Rocker arm 5, Returnning spring 2, secured core 7 is fixed in the casing 1, electromagnetic coil 8 is installed on the secured core 7; Rocker arm 5 is hinged on the casing 1; end of Rocker arm 5 is clutch iron core 6 and corresponding with secured core 7 fixedly; the other end of Rocker arm 5 is provided with roller 4 and cooperates with the draw-in groove of sliding clutch 9, and Returnning spring 2 is enclosed within on the output shaft 15 between reverse clutch 3 and the driven gear 16.

When the utility model normally moves, electromagnetic coil 8 no electric circuit work, clutch iron core 6 is in separated state with secured core 7, and under the effect of Returnning spring 2, sliding clutch 9 combines with gearwheel 10, and reverse clutch 3 separates with driven gear 16.Its working procedure is as follows, when control motor forward rotation, input shaft 14 drives driving gear 20, driving gear 20 drives driven gear 16 by intermediate gear 19 and rotates, driven gear 16 drives output shaft 15 by one-way element and is rotated in the forward, and this moment small gear 12 since one-way element oppositely idle running do not rotate with input shaft 14, thereby first kind of speed that output is set and moment of torsion.When motor reverses, input shaft 14 not only drives driving gear 20 but also drive small gear 12 by one-way element, small gear 12 drives gearwheel 10 and rotates, gearwheel 10 drives output shaft 15 by the one-way element on sliding clutch 9 and the sliding clutch 9 and is rotated in the forward, thus second kind of speed that output is set and moment of torsion; This moment, driving gear 20 drove driven gear 16 by intermediate gear 19, because the reverse driven gear 16 of one-way element produces idle running.

When needs are moveed backward, electromagnetic coil 8 energising work, clutch iron core 6 under the electromagnetic force effect with secured core 7 adhesives and drive Rocker arm 5, behind the elastic force that overcomes Returnning spring 2; Rocker arm 5 promotes reverse clutch 3 and combines with driven gear 16, and sliding clutch 9 separates with gearwheel 10.Its working procedure is as follows, control motor backward rotation, input shaft 14 drives driving gear 20 and small gear 12 simultaneously, driving gear 20 drives driven gear 16 by intermediate gear 19 and rotates, driven gear 16 drives output shaft 15 counterrotatings by reverse clutch 3 and by spline tooth, thereby realizes the purpose of reversing; This moment, gearwheel 10 dallied under the drive of small gear 12.
