Abstract
The utility model relates to a wheel brake of a power-driven or man-power tricycle, belonging to tricycle brakes; a brake drum is fixedly connected with a wheel axle of the tricycle, a brake shoe is arranged on a brake bottom plate and is arranged in the brake drum, and the brake bottom plate is fixedly connected with a tricycle carriage. Punching holes are uniformly distributed on the bottom surface of the brake drum, so as to lead gyration quality to be balanceable and lighten loading; the mechanical efficiency of the tricycle is improved and the mechanical abrasion is reduced, thereby increasing the reliability of the tricycle and the safety of people.
Description
Affiliated technical field
The utility model belongs to braking element and the layout that relates to three-wheel vehicle.
Background technology
Electro-tricycle and manual tricycle are the widely used load transport facilitys in present rural area.But the car side brake of these three-wheel vehicles generally all adopts plate disc brake.Owing to produce relative displacement between disc and the adjacent members when three-wheel vehicle is advanced, disc is offset, cause slipping of brake, and, the axial width of three-wheel vehicle hind axle is big, constitutes centrifugal inertia force when its unbalance mass, perpendicular to hind axle ties up to wheel, causes the additional friction power and the additional stress of each kinematic pair, make the hind axle distortion, cause drg self-locking or malfunctioning; Especially when road jolted, the three-wheel vehicle vehicle body vibrated, and the rotating member relative motion of disc and axletree produces the friction force that stops wheel revolutions in its kinematic pair, consume a part of electrical motor or manpower input work, reduces the three-wheel vehicle mechanical efficiency; Simultaneously, the mechanical wear that the rotating member of disc and axletree produces can influence the intensity and the functional reliability of drg, causes the three-wheel vehicle safety to reduce, and shortens its service life.
Summary of the invention
In order to overcome present electro-tricycle and manual tricycle slipping of brake, additional friction power and to the wearing and tearing of kinematic pair, improve the mechanical efficiency of three-wheel vehicle and the reliability of drg, prolong its service life, the utility model provides a kind of car side brake of electronic or manual tricycle.
The utility model is realized in the following manner:
Brake wheel 2 is fixedly connected with the wheel shaft 1 of three-wheel vehicle, and the brake shoe brake cheek 4 that is installed on the back-plate 5 is inserted in the brake wheel 2, and the vehicle frame of back-plate 5 and three-wheel vehicle is fixedly connected.
Described brake wheel 2 bottom surfaces have even layout to punching 10, so that its rotating mass balance and alleviate load.
The utility model brake wheel and three-wheel vehicle wheel shaft are fixedly connected, promptly with brake wheel as rotating member, when advancing, three-wheel vehicle rotates with wheel, be installed in vehicle frame and be fixedly connected on the back-plate and insert brake shoe brake cheek in the brake wheel, brake shoe brake cheek is a driving surface with the brake wheel inner cylinder face, when the three-wheel vehicle glancing impact, the crank of pulling brake shoe brake cheek makes rectangle or has the crankshaft rotation certain angle of flange, overcome the tightening force of spring, original two the arc hoof faces that close up that promote brake shoe brake cheek radially open, its arc hoof face tightly is pressed on the brake wheel, and friction brake drum, brake wheel and wheel are stopped operating.
Relative displacement can not take place in the utility model and axletree, has improved the safety of three-wheel vehicle; The rigid construction member of being made up of brake wheel, brake shoe brake cheek and back-plate can be avoided taking turns shaft distortion and body vibrations and cause the additional stressed and friction force that produces of rotating member, eliminate or reduced input work to change heat energy into and expending of bringing, improve its mechanical efficiency, reduce its mechanical wear, thereby increased working of brakes reliability and people's thereof safety.
Description of drawings
Fig. 1 is the utility model scheme drawing.Comprise among the figure: the wheel shaft 1 of three-wheel vehicle, brake wheel 2, bearing 3, brake shoe brake cheek 4, back-plate 5, crank 6, bolt 7, bearing frame 8, back-plate screw 9, punching 10, brake shoe brake cheek spring 11.
Be described further below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, back-plate 5 connects with the vehicle frame of three-wheel vehicle by back-plate screw 9 usefulness bolts, brake wheel 2 is fixedly connected with the wheel shaft 1 usefulness bolt 7 of three-wheel vehicle, brake shoe brake cheek 4 is installed on the back-plate 5, and insert in the brake wheel 4, the crank 6 of its brake shoe brake cheek 4 connects with the brake of three-wheel vehicle by connecting rod.
Brake wheel 5 bottom surfaces have well-distributed to punching 10, make brake wheel 5 rotating mass balances, and alleviate three-wheel vehicle load.
