Abstract

The utility model discloses a bidirectional driver especially suitable for a manpower cycle, which is characterized in that a chain on a driving chain wheel can simultaneously pass round two driven chain wheels with overdrive clutches, wherein, one overdrive clutch in the two driven chain wheels is forwards arranged; the other overdrive clutch is backwards arranged. The positive and negative alternative rotations of the driving sprocket can be converted into unidirectional rotation through the switching of a gear. The driving chain wheel and the driven chain wheels can be replaced by gears; the direct engagement of a driving chain wheel and the two driven gears with the overdrive clutches through chains is cancelled; one overrunning clutch of the two overrunning clutches is forward arranged; the other overrunning clutch is arranged backwards; the positive and negative alternative rotations can be converted into the unidirectional rotation.

Description

The rickshaw bidirectional driving apparatus

The utility model is the improvement to available man-power three-wheel vehicle, perambulator, bicycle type of drive.

Existing rickshaw all drives car with foot to a direction drive sprocket and advances.People's shank is only some muscle participation work all the time, is unfavorable for human potential's performance, also is unfavorable for all round exercise of muscle.

Though Patent Office of the People's Republic of China discloses a kind of " the two-way foot of bicycle is stepped on device " in CN2209103Y number bulletin, the utility model by comparison, obviously structure is more simple, it is lower to implement easy cost.When

gear

5 and 6 varies in size, can realize that also forward pedals with oppositely pedaling and have different speed ratios.

The purpose of this utility model is exactly for a kind of rickshaw that can positive and negative driving can obtain different speed ratios again is provided to people.

In order to achieve the above object, this device has adopted following technical scheme (see figure 1)

On wheel shaft 10, be fixedly connected with cover 7, flywheel 3 connected firmly with gear 5 be in the same place again by overlapping 7.The moving cover 8 that is associated with is fixedly connected with flywheel 4 and gear 6 on the cover 8 on tween drive shaft 9, and the chain 2 on the drive sprocket 1 is walked around flywheel 3 and 4, and flywheel 3 forwards are installed, and flywheel 4 is oppositely installed.Gear 5 and 6 engagements, size can be identical also can be different.

When just pedaling, initiatively chain drum 1 drives flywheel 3 and 4 forward rotation by chain 2, and flywheel 3 forwards are installed, and can drive cover 7 and gear 5 and rotate with wheel shaft 10; Oppositely the flywheel of installing 4 but can not drive cover 8, and the gear 6 on the cover 8 is driven by gear 5, can only oppositely dally around tween drive shaft 9.

During back-pedalling, initiatively chain drum reverses together by chain 2 drive flywheels 3 and 4, and the reverse flywheel of installing 4 can drive cover 8 and gear 6 reverses together, and the flywheel 3 that forward is installed but can only dally, obtain the gear 6 and gear 5 engagements of power, still just change by overlapping 7 drive wheel shafts 10.

Step on device enough with other both sides and compare, this design obviously wants letter to refine manyly, and implements easily, uses reliable.

Description of drawings:

Fig. 1 is the basic structure of " rickshaw both sides driving device ".

Fig. 2 is " rickshaw both sides driving device " application on manual tricycle.

Fig. 3 uses " rickshaw two-way drive device " design-calculated health tourism car.

Embodiment:

Example 1: " rickshaw both sides driving device " application on manual tricycle.(see figure 2)

This routine middle gear 5 is bigger than gear 6, so the speed of a motor vehicle is fast when forward is pedaled, the speed of a motor vehicle is slow when oppositely pedaling, and is fit to go up a slope.

Example 2: the application of two-way drive device on the health tourism car:

Two overlapped independently drive system before and after the health tourism car had, and before driving is pedaled to temper lower limb with foot, and push-and-pull drove before and after rear drive was done with hand, tempered upper limbs and back.

When drive spindle 11 swings, the sector 13 of axle on 12 drives the gear 14 that is engaged with and swings with the 14 coaxial sprocket wheels that connect firmly 1, makes the work of two-way drive device, thereby the hand-drive system is played a role.

Claims

1, a kind of positive and negative direction drives the rickshaw bidirectional driving apparatus that car is advanced, and this device is specially adapted to rickshaw, also can be used for other machinery.It is characterized in that the chain (2) on the drive sprocket (1) walks around flywheel (3) and (4) simultaneously, cover (7) and cover (8) connect firmly gear (5) and (6) together with flywheel (3) and (4) respectively, cover (7) connects firmly with wheel shaft (10), cover (8) and the moving connection of tween drive shaft (9).

2, the described bidirectional driving apparatus of claim 1, it is characterized in that: the gear ring on drive sprocket (1) and flywheel (3), (4) replaces with gear, and cancellation chain (2) allows driving gear and ring gear directly mesh, other structures are constant, and its function is identical with claim 1.
