Description
Technical field
The utility model relates to a kind of gearbox of built-in braking system.
Background technique
Domestic existing fork truck has two kinds of forms, a kind of be with internal-combustion engine as power, another kind is as power with motor.Big with internal-combustion engine as the fork truck power of power, but the waste gas of internal-combustion engine and noise pollution are serious.And motor as the power fork truck with its favorable environment protection energy, just more and more come into one's own, output is increasing.Domestic similar with Electric Fork Lift Trucks its structure of gearbox and general internal combustion engine fork lift gearbox, its structure all is from prime mover input power, then by the gearbox speed change, through differential mechanism and two-semiaxle power is passed on the wheel, Vehicular turn is mainly finished by differential mechanism, and more car brakeing is adopted big, the baroque hub-type of volume to rise and stopped.Because gearbox power transmission chain length, its machinery driving efficiency is lower.Simultaneously, because gearbox transmission of power part is more, and also have parts such as differential mechanism, break, the cost of production of gearbox is also higher.
The model utility content
The purpose of this utility model is to provide a kind of gearbox of built-in braking system, have simple in structure, volume is little, in light weight, transmission efficiency is high, the characteristics of built-in braking system.
In order to achieve the above object, the technical solution of the utility model is:
A kind of gearbox of built-in braking system, comprise housing, on housing, be installed with input shaft, be installed with driving gear on the input shaft, be movably installed with gearwheel on the housing, driving gear and gearwheel engagement, the gearwheel side links to each other with the friction horse that is provided with gear, friction plate and outside friction disc in being equipped with on the friction horse, and outside friction disc contacts with platen, outside friction disc links to each other with ring gear again, planet carrier is installed in the ring gear, and planet carrier links to each other with output shaft, is connected with planetary gear set on the planet carrier, ring gear and output shaft are separately fixed on the housing, and the rocking arm braking device is installed on the housing.
Described planetary gear set comprises planetary pinion, cooperate on the planetary pinion internal diameter to be provided with bearing, bearing by inner ring and the cylindrical roller that directly is covered with on inner ring forms, planetary pinion is meshed with ring gear and gear on the horse that rubs respectively.Compare with traditional bearing, substituted bearing outer ring by planetary pinion, and do not had retainer between the bearing roller, overall structure is reduced, body diameter increases, and the external force that can bear also increases.
Described rocking arm braking device comprises the push rod that flexibly connects with housing, push rod is connected with by Xiao's axle and is installed in brake lever on the housing, is connected with piston in the brake lever, and piston one end is equipped with piston rod, the piston the other end is with return spring, and upper cover of piston rod has dirt-proof boot.
Pass through bearing fixing between described housing and the input shaft.
Flexibly connect by bearing between described gearwheel and the housing, described gearwheel with rub between the horse, all be connected between ring gear and the housing by bolt.Be provided with 6 bolts between gearwheel and the friction horse, be provided with 10 bolts between ring gear and the housing.
In described between friction plate and the horse that rubs, between outside friction disc and the ring gear, all be connected between planet carrier and the output shaft by spline.
The rocking arm braking device forms whole braking system with interior friction plate and outside friction disc, and the whole braking system and the gear box casing of gearbox are joined together, thereby produces the skidding effect.
After the utility model adopted technique scheme, its beneficial effect was:
Structure of the present utility model no longer needs to pass through earlier the gearbox speed change, power is passed on the wheel through differential mechanism and two-semiaxle then again; Vehicular turn also ends the dependence upon differential mechanism and finishes; Car brakeing is also no longer adopted big, the baroque hub-type of volume to rise and is stopped.But adopted the gearbox of built-in braking system, power transmission, Vehicular turn, braking is all finished in gearbox, and transmission, brake member are reduced to some extent, and cost of production decreases, and employing is that two gearboxes are installed respectively on two wheels, finish Vehicular turn by two gearbox speed discrepancies, and compare with traditional gearbox, power chain shortens.Thereby make the utlity model has simple in structure, volume is little, in light weight, characteristics that transmission efficiency is high.

Embodiment
As shown in Figure 1, a kind of gearbox of built-in braking system, comprise housing 20, input shaft 3 is fixed on the housing 20 by bearing 1 and bearing 2, be installed with driving gear 4 on the input shaft 3, on housing 20, be movably installed with gearwheel 5 by bearing 6, driving gear 4 and gearwheel 5 engagements, gearwheel 5 sides link to each other with the friction horse 7 that is provided with gear 73 by 6 bolts, friction plate 71 and outside friction disc 72 in being equipped with on the friction horse 7, outside friction disc 72 contacts with platen 13, outside friction disc 72 links to each other with ring gear 16 again, planet carrier 12 is installed in the ring gear 16, planet carrier 12 links to each other with output shaft 17, be connected with planetary gear set 15 on the planet carrier 12, between interior friction plate 71 and the friction horse 7, between outside friction disc 72 and the ring gear 16, all be connected between planet carrier 12 and the output shaft 17 by spline, ring gear 16 and output shaft 17 are separately fixed on the housing 20, ring gear 16 is bolted on the housing 20 by 10, output shaft on housing 20, is equipped with rocking arm braking device 8 by bearing fixing on the housing 20.
As shown in Figure 2 to Figure 3, planetary gear set 15 comprises planetary pinion 151, cooperate on planetary pinion 151 internal diameters and be provided with bearing 15 ', bearing 15 ' is made up of inner ring 153 and the cylindrical roller 152 that directly is covered with on inner ring, and planetary pinion 151 is meshed with gear 73 on ring gear 16 and the friction horse 7 respectively.Compare with traditional bearing, substituted bearing outer ring by planetary pinion 151, and do not had retainer between the bearing roller, overall structure is reduced, body diameter increases, and the external force that can bear also increases.
As shown in Figure 4; rocking arm braking device 8 comprises the push rod 81 that flexibly connects with housing 20; push rod 81 is connected with by Xiao's axle 87 and is installed in brake lever 82 on the housing 20; be connected with piston 85 in the brake lever 82; piston 85 1 ends are equipped with piston rod 84; piston 85 the other ends are with return spring 86, are with dirt-proof boot 83 on the piston rod 84.
