Abstract
The utility model discloses a forth and back pedaling health care propulsion device for bicycles. Two bevel gears which are arranged on a centre shaft by a bearing are joggled with a bevel gear which is arranged on a casing; the centre shaft between the two bevel gears are provided with a sliding clutch sleeve which can respectively joggled with the two bevel gears; one side of the centre shaft is provided with a wheel disk; the wheel disk is connected with the bevel gears; the utility model realizes forth and back pedaling for bicycles, and is especially suitable for physical training.
Description
The utility model relates to a kind of bicycle drive.
Foot-operated chain wheel driving mechanism voluntarily, when stepping on forward, bicycle travels forward, and flywheel idle running when post legged.
No matter the purpose of this utility model provides a kind of driving device of just stepping on or stepping on bicycle all can be to overtake.
The technical solution of the utility model is as follows:
Bicycle is just being stepped on the body-building propelling unit, two bevel gears that are contained on the axis by bearing mesh with a bevel gear that is contained on the casing, on the axis between two bevel gears, be equipped with one can with bevel gear ingear slide engaging and disengaging cover respectively, in a side of axis a wheel disc that joins with bevel gear is housed.
The utility model has the advantages that: owing to just step on bicycle and all can advance, people reach the purpose that makes multi-section position more obtain taking exercise by changing foot-operated direction in the process of riding.
Further specify below in conjunction with accompanying drawing.
Fig. 1 is a cutaway view of the present utility model.
By bearing umbrella tooth 2 and 4 are housed on the axis 5 in the drawings, umbrella tooth 2,4 and the passive umbrella tooth 3 that is contained on the casing 6 mesh, a slide engaging and disengaging cover 7 is housed on the axis between umbrella tooth 2 and 4, the slide engaging and disengaging cover can axially moving in chute along axis, slide engaging and disengaging cover sway can mesh respectively with umbrella tooth 2,4, side at axis is equipped with wheel disc 1, the big trochal disc that wheel disc 1 rotates for bicycle chainwheel.
The bicycle fitness equipment is by axis people's pedal power to be passed to slide engaging and disengaging to put, and when transmission shaft rotated forward, the slide engaging and disengaging cover relied on the right, drives the umbrella tooth 2 that has wheel disc and rolls, and at this moment whole car has just moved.
Because two umbrella teeth about being equipped with on the transmission shaft, the centre has a bevel pinion to do engaged transmission, so when rotating before the umbrella teeth directional on the right, the umbrella tooth 4 on the left side rotates backward synchronously.When to post legged, the slide engaging and disengaging cover relies on the bevel gear 4 and its engagement on the left side, drives car and advances.
