The utility model aims at the problems that the existing electric winch brake is a complex structure, high production cost, low general work efficiency of the winch, big wearing, removing and repairing in difficult of the existing electric winch brake, which provides a star wheel brake mechanism for an electric winch of the vehicle that is a simple structure, convenient for manufacturing, low production cost, high general work efficiency of the winch, small wearing, convenient removing and repairing, the utility model includes a brake ring, a star wheel, a roller, a spring, a poke shaft, a roller pin, a retainer ring and a packing ring. A plurality of axial cuniform grooves are arranged on the star wheel, a roller and a spring are arranged in each cuniform groove respectively, a plurality axial semicircle grooves is arranged on the poke shaft, a roller pin is arranged respectively in the semicircle grooves on each poke shaft, one end of the roller pin is inserted in the cuniform groove on the opposite star wheel.
Description
Technical field
The utility model relates to the braking mechanism technical field, particularly a kind of star-wheel braking mechanism that is used on the Electirc capstan for vehicles.
Background technology
Existing electric capstan brake is to adopt piston ring type or awl drum-type friction type braking mechanism, though its serviceability of this braking mechanism is more stable, exists complex structure, productive costs height, the capstan winch efficient of always working is on the low side, and wearing and tearing are big, service life is short, dismounting, the inconvenient weak point of maintenance.
Summary of the invention
The utility model is at the existing electric capstan existing complex structure that brakes, the productive costs height, the capstan winch efficient of always working is on the low side, and wearing and tearing are big, and service life is short, dismounting, the inconvenient weak point of maintenance, provide a kind of simple in structure, be convenient to manufacture, productive costs is low, the total high efficiency of capstan winch, wearing and tearing are little, stable and reliable for performance, the life-span is long, dismounting, Electirc capstan for vehicles star-wheel braking mechanism easy to maintenance.
The technical scheme that the utility model Electirc capstan for vehicles star-wheel braking mechanism adopts is finished in the following way: Electirc capstan for vehicles star-wheel braking mechanism comprises trig loop, star-wheel, roller, spring, shifting shaft, needle roller, back-up ring A, piston ring A, back-up ring B, piston ring B, star-wheel is contained in the trig loop endoporus one by back-up ring A, piston ring A, shifting shaft is contained in other end in the trig loop endoporus by back-up ring B, piston ring B, the input shaft of star-wheel and speed reduction gearing links, and the output shaft of shifting shaft and motor links; Star-wheel is provided with several axial webge slots, several webge slots and trig loop on the star-wheel constitute several wedge shape spaces, in the wedge shape space that webge slot on each star-wheel and trig loop constitute a roller and a spring are housed respectively, make roller can freely rotate in one direction, another direction is owing to interfere between roller, star-wheel and trig loop three and do not rotate (braking), makes the star-wheel can only unidirectional rotation; Shifting shaft is provided with several axial semi-circular groove, the notch of the webge slot on the notch of the semi-circular groove on the shifting shaft and the star-wheel is corresponding, a needle roller is housed respectively in the semi-circular groove on each shifting shaft, is located in the webge slot that is inserted on the corresponding star-wheel of the needle roller in the semi-circular groove on the shifting shaft; Rotation between shifting shaft and the needle roller is equivalent to a needle bearing rotates, and the while shifting shaft stirs roller by needle roller or star-wheel can two-wayly rotate, and transmitting torque is given retarder.
The utility model Electirc capstan for vehicles star-wheel braking mechanism is compared with existing electric capstan brake, have simple in structurely, be convenient to manufacture, productive costs is low, the total high efficiency of capstan winch, wearing and tearing are little, stable and reliable for performance, the life-span is long, dismounting, characteristics easy to maintenance.
