The specific embodiment

Contrast accompanying drawing below, the utility model is described in further detail by embodiment.

To accompanying drawing 4, a kind of pedal type bicycle for old people includes with reference to accompanying drawing 1: handlebar 1, governor 2, bicycle basket 3, vehicle frame 4, seat 5, wheel 6, brake 7, foot pedal apparatus 8, chain 9, three fast flywheels 10, hind axle 11, boot 12 up and down; Its key is: foot pedal apparatus 8 is connected on the middle bottom of vehicle frame 4 up and down, up and down foot pedal apparatus 8 by common adapter shaft between upper box 20 and the lower box 21 to the anchor shaft 22 that be arranged in parallel, hollow shaft 23, the nail axle 24 that connects vertical direction, be connected the bevel gear 25 on the nail axle 24, handle 26 is stepped on a left side that is connected and fixed axle 22 two ends, handle 27 and pedal 28 are stepped in the right side, 28 ' be connected the ratchet 29 of both sides in the middle of the hollow shaft 23,29 ' and the clutch sprocket wheel 30 of an end, the spindle nose of plug 31 is connected tooth embedding clutch discs 32 jointly in hollow shaft 23 and the hole, the other end connects spring 33, bearing carrier ring 34 and upper box 20, lower box 21 is connected, also connect bearing 35, lever 36 1 ends connect on the bearing 35, and is pressing on the head of plug 31 at its middle part.Also have bevel gear 25 mesh respectively that handle 26 is stepped on a left side, the umbrella tooth piece on the handle 27 is stepped on the right side, a left side step on handle 26, the right side step on straight-tooth piece on the handle 27 distinguish mesh ratchet gear 29,29 ' on the straight-tooth piece; Tooth embedding clutch discs 32 and clutch sprocket wheel 30 upper surface teeth are meshed.A left side step on handle 26, the right side step on the one side of the straight-tooth piece on the handle 27 connect respectively link stopper 37,37 ', a left side step on handle 26, the right side step on the handle 27 endoporus connect respectively capping 38,38 '.Hollow shaft 23 and ratchet 29,29 ' inner ring be all one.

Can see that from implement illustration the vital parts of critical component and by grease lubrication, all is equipped with bearing with the resistance that reduces friction in rotation place all in last lower box.

The utilization and operation of this car is such, and when the people takes seat 5, it is downward that people's pin is stepped on pedal 28, and the straight-tooth piece that a left side is stepped on the handle 26 drives ratchet 29 no effects idle running.A left side steps on that umbrella tooth piece on the handle 26 drives bevel gear 25 and the right umbrella tooth piece of stepping on the handle 27 makes pedal 28 ' upwards swing in addition, the right side step on straight-tooth piece on the handle 27 drive ratchet 29 ' on the straight-tooth piece, ratchet 29 ' effect under, hollow shaft 23 is rotated, by tooth embedding clutch discs 32 engagement clutch sprocket wheels 30, drive chain 9 and three fast flywheels 10, hind axle 11 is rotated, wheel 7 rolls forward.Same former should people's pin step on pedal 28 ' after, clutch sprocket wheel 30 is rotated, so two top-cross for pin step on pedal 28,28 ', car is moved ahead continuously.When car was wanted speed governing, the right handles that staff is pulled on the governor 2 just can speed governing.When car will fall back, the left handle that staff is pulled on the governor 2 just can make lever 36 press plug 31, made tooth embedding clutch discs 32 throw off clutch sprocket wheel 30, and car just can fall back and freely roll, and down original position is pulled governor 2 left handles in the back of falling back.Tooth embedding clutch discs 32 is combined with the clutch sprocket wheel under the effect of spring 33, and car just can have been stepped on row.
