Abstract
The utility model relates to a vehicular graded pneumatic braking device for effectively relieving serious abrasion produced by friction braking by using the braking principle of compressed air. The device consists of a frame, left and right symmetrical rear wheel braking transmission gears, a front wheel braking transmission gear, a transmission rack, transverse H-shaped friction strips, round table shaped transmission friction wheels, half shaft round table shaped friction wheels, a transmission rod, a crankshaft and a braking cylinder. The device has the advantages of effectively lightening abrasion of a brake component due to the conventional friction braking so as to reduce the replacing frequency of the component, effectively reduce brake failure caused by the abrasion of the component and reduce accidents. In addition, the moving distance of the transmission rack is changed by changing the magnitude of a force applied to a pedal, so that graded braking control of front and rear wheels is realized; and the device is simple in structure and low in manufacturing cost.

The specific embodiment:
Among the figure: 1, link to each other connecting rod 9, trailing wheel braking transmission gear 10, driving rack 11, front wheel brake transmission gear 12, front wheel brake transmission gear link to each other connecting rod 13, piston 14, bent axle 15, pedal 16, brake cylinder 17, connecting rod 18, pull back spring 19, piston/cylinder of the round table-like friction wheel of vehicle frame 2, wheel 3, I shape fricting strip 4, round table-like gearing friction wheel 5, semiaxis 6, semiaxis 7, waling stripe 8, trailing wheel braking transmission gear
This installs left-right symmetric.It is the groove of smooth surface that frame about 1 ends have an inside respectively, and oilhole is arranged in the groove, is used to lubricate, and I shape fricting strip 3 is installed in the groove, can in groove, slidably reciprocate.The fricting strip front end links to each other with piston 13 through connecting rod 17, and piston bottom has groove, with compression ring and oil ring are installed, are used to strengthen sealing effectiveness and reclaim lubricating oil.Piston is installed in the piston/cylinder 19 on the frame, through the air in the compression piston cylinder body, the kinetic energy of car is converted into the interior ability of gas.The lower surface of I shape fricting strip 3, round table-like gearing friction wheel 4, the round table-like friction wheel 5 of semiaxis all is to be processed by material wear-resisting and that surface friction coefficient is big, the surface has fine pattern to be beneficial to the enhancing friction.When the needs glancing impact, these three parts are in contact with one another the piston that the friction power transmission links to each other for the I shape fricting strip, and then pressurized air is with braking.Driving rack 10 upper ends link to each other with brake cylinder 16; When pedal 15 is stepped on; Air cylinder driven driving rack 10 moves down; Tooth bar 10 will drive symmetrical trailing wheel braking transmission gear 9 and rotate, and then drives connecting rod 8 motions that are installed on the gear, and the round table-like gearing friction wheel 4 of waling stripe 7 drives and the lower surface and the round table-like friction wheel 5 of semiaxis of I shape fricting strip 3 are joined.When pedal 15 bigger again words firmly; Tooth bar 10 will arrive and move down the position that links to each other with front wheel brake transmission gear 11; (being installed on front wheel brake transmission gear connecting rod 12 links to each other with bent axle 14 in the braking of realization front-wheel; Crankshaft two end links to each other with disc type brake disc on being installed on the front-wheel nave boss), this moment, front and back wheel all was in braking mode.Round table-like gearing friction wheel 4 and the round table-like friction wheel 5 of semiaxis all are two of branch front and back, like Fig. 3,4,5,6, link to each other through bolt, are beneficial to replacing.Round table-like gearing friction wheel 4 is inner as shown in Figure 5 to have vertical circular trough, links to each other with the circular discs of waling stripe 7 front ends, is beneficial to the rotation that round table-like gearing friction is taken turns.There is a keyway the round table-like friction wheel of semiaxis 5 inside, and corresponding positions is equipped with a keyway on the semiaxis 6, and both connect through key, thereby it is rotated with semiaxis, and both do not produce slip.The effect of pull back spring is not give under the situation of the pedal application of force, and each parts returns original position, and braking is removed.
