Description
The utility model relates to a kind of manual tricycle that takes a bus instead of walking, especially a kind of hand-held design manual tricycle with the left brake lever direct control trailing wheel braking on the handlebar.
Hand-held design manual tricycle commercially available at present and that people use is the manpower transportation of a kind of energy small article going along with, because volume is little, it is light to ride, and can under the handlebar situation three-wheel vehicle not carried out brake operating at both hands, is well suited for the elderly and uses.This class hand-held design manual tricycle, it comprises two trailing wheels and a trailing wheel brake equipment, each trailing wheel is contained in the end of trailing wheel macro-axis respectively, one of them trailing wheel and trailing wheel macro-axis are connected, another trailing wheel and trailing wheel macro-axis are rotationally connected, and the trailing wheel macro-axis inserts in two coaxial axle beds on the wagon box collet left-right symmetric frame rotationally; The trailing wheel brake equipment mainly by a left brake lever, drg, and an one end form with the transmission device that left brake lever links to each other.Drg adopts external contracting drum brake, it have one with trailing wheel macro-axis bonded assembly brake wheel and a brake collar that centers on the brake wheel periphery, brake collar one end is connected with the wagon box collet, the other end links to each other with the other end of transmission device.When need be to the three-wheel vehicle glancing impact that travels, with the left brake lever on the left hand grip handlebar, left side brake lever applies one by transmission device to one end of the brake collar in the drg and tightens up pulling force, this pulling force makes brake collar compress the brake wheel periphery, produce friction, utilize this friction force to force the brake wheel of rotation to slow down, reach a trailing wheel braking purpose that is connected on the trailing wheel macro-axis.
This class hand-held design manual tricycle, its external contracting drum brake glancing impact, and provide by transmission device by the left brake lever of holding with a firm grip the pulling force of brake collar, and value of thrust is generally little, thereby deceleration and stopping performance is not good; Because external contracting drum brake is directly exposed in the external environment, and dust, dirt easily attach on a pair of friction surface of drg, thereby have lowered the friction coefficient of friction pair, rear wheel brake is ineffective, brings hidden danger to traffic safety again.
For this reason, the purpose of this utility model provides the good hand-held design manual tricycle of a kind of trailing wheel deceleration and stopping performance.
For achieving the above object, the utility model provides a kind of hand-held design manual tricycle of following structure, this hand-held design manual tricycle, it comprises two trailing wheels and a trailing wheel brake equipment, described each trailing wheel is contained in the two ends of trailing wheel macro-axis respectively, the big shaft end of one of them trailing wheel and trailing wheel is connected, and another trailing wheel and trailing wheel macro-axis the other end are rotationally connected, and this trailing wheel macro-axis inserts in two coaxial axle beds on the wagon box collet left-right symmetric frame rotationally; Described trailing wheel brake equipment mainly is made of a left brake lever, an one end and left brake lever bonded assembly transmission device and drg, described drg has two, be located at the wheel hub position of each trailing wheel respectively, described two drgs adopt respectively with rear wheel hub in the internal expansion type drum brake that is combined into one of floral disc, they are captiveed joint with collet, and described two drgs are connected with the other end of described transmission device by a link gear.
Described internal expansion type drum brake, the brake wheel that to have its inside face be the face of cylinder, an end of brake wheel is uncovered, on uncovered mouth limit the ring limit of turning up is arranged, and the through hole that is used to install spoke of many circumference uniform distributions is arranged on the ring limit; The other end of brake wheel to the hole that has to can be used for installing steel bowl or set collar, reaches one and rear axle tube bonded assembly hole along axis shaft; At the brake wheel opening end a close locating plate is arranged, have in the locating plate one with the brake wheel inside face coaxial be used for the hole of passing through by the trailing wheel macro-axis, an intrinsic rest pin on described locating plate plate face inwardly; The brake scotch that two symmetric offset spread are arranged in the brake wheel, each brake scotch is fixed with a circular arc friction shoe respectively on the limit of brake wheel inside face; Two brake scotch two ends and rest pin of an end in the same way are rotationally connected, described two brake scotch have one to ship and resell on another market between two opposing end surfaces of the other end in the same way, described shipping and reselling on another market has the head that its cross-sectional plane is a waist shape, relative with described two brake scotch respectively two end faces contact in two opposite flanks of waist shape head; Two spaced-apart extension springs that they are connected together are arranged respectively between described two brake scotch inner edges, and the friction shoe outside face and the brake wheel inside face of two brake scotch are gapped; Describedly ship and resell on another market protrudingly from locating plate, and rotatable, at the intrinsic connecting arm in position of shipping and reselling on another market and stretching out locating plate, the free end of connecting arm has a connecting bore that can link to each other with described link gear; A fixed orifice is arranged on the described locating plate.
Owing on each trailing wheel, be provided with an internal expansion type drum brake that is combined into one with the trailing wheel floral disc, and two drgs are connected with transmission device, left brake lever successively by a link gear, operate left brake lever, can be simultaneously to two trailing wheel brakings, the more single drg of deceleration and stopping performance is good, stable; The arm of force of each drg connecting arm is more much bigger than the support arm of the waist shape head of shipping and reselling on another market, according to lever principle, be delivered to pulling force on the connecting arm by left brake lever, power by the waist shape head support arm of shipping and reselling on another market is amplified, the power that makes friction shoe push against the brake wheel inside face strengthens greatly, and under left brake lever provided identical pulling force, the lock torque that the internal expansion type drum brake produces was big, deceleration and stopping performance is good, the brake spirit.In addition, a pair of friction surface of internal expansion type drum brake is in brake wheel, and extraneous dust, foreign material are difficult for entering, and the friction coefficient of friction surface changes little, and deceleration and stopping performance is stable.
