Abstract
The utility model relates to a gear type direction changing apparatus for a body building bicycle. The utility model comprises a housing, and an input shaft, an output shaft, a connecting movable sleeve, a shifting fork movable disc with a shifting fork, a connecting sleeve barrel, front and opposite flywheels, an inner spline sleeve and an outer spline disc are arranged in the housing. The utility model has the advantages that the utility model has a neutral, and the pedals of the pedal type body building bicycle does not rotate in an empty way.
Description
The utility model relates to the body-building apparatus field in the sports goods, particularly relates to a kind of pedal-type fitness bicycle and advances and switch the reversing arrangement of usefulness with fallback mode.
Existing pedal-type fitness bicycle motion mode is generally a kind of mode of advancing, and abroad also has to advance and the pedal-type fitness bicycle appearance that retreats dual mode.Preceding a kind of exercising pattern is single, and lacks interesting: a kind of no neutral gear transition in back, and dual mode switches direct, and the relevant parts of fragile reversing arrangement do not have neutral gear in addition, are unfavorable for demiware or professor's movement technique among a small circle.And all there is same disadvantages in existing above-mentioned two kinds of pedal-type fitness bicycles: when pedal-type fitness bicycle with inertia motion particularly during descending, though pin is not stepped on, step brings discomfort in idle running to the sporter, children particularly, even can damage its lower limb.
The purpose of this utility model is to overcome above-mentioned defective, designs a kind of advancing and the exercycle gear type reversing arrangement that retreats easy switching, has neutral gear and the step of pedal-type fitness bicycle is not dallied.
The purpose of this utility model realizes with following technical scheme: exercycle gear type reversing arrangement, has a housing, adjacent power shaft and the output shaft of being coaxially set in the housing, the power shaft and the output shaft that are in the housing side are provided with bearing outward, be connected with the connection kink by single false key outside the power shaft in housing, connect outside the kink and be connected with the shift fork removable pan that has shift fork by the activity of kink bearing, adjacent connection kink also is fixedly connected with it and is in the coupling sleeve of power shaft and output shaft adjacent part periphery, positive flywheel and anti-flywheel that the coupling sleeve inboard is fixedly connected and arranges vertically, just, anti-flywheel is with the opposite installation that turns to, output shaft with just, be provided with between anti-flywheel with just, the inner spline housing of anti-flywheel thread connection, inner spline housing with just, the middle part of anti-flywheel thread connection part has the inner spline housing cavity, be set with on the output shaft and the corresponding outer spline disc of inner spline housing cavity axial width, outer spline disc and inner spline housing are the splined of living.
As the further technical measures of aforementioned schemes, be set with centring ring between described coupling sleeve and positive and negative flywheel.
As the further technical measures of aforementioned schemes, described connection kink and coupling sleeve are by Bolt Connection.
As the further technical measures of aforementioned schemes, described coupling sleeve and positive and negative flywheel are connected and fixed by welding.
As the further again technical measures of aforementioned schemes, described outer spline disc and output shaft are made one.
As the further again technical measures of aforementioned schemes, fixing between described coupling sleeve and positive and negative flywheel, centring ring for welding.
During the utility model work, shift fork is dialled to an end (for example left end), the shift fork removable pan promoted to connect kink and slided to the right and (connect for single false key because of connecting between kink and output shaft this moment, can slide relatively), and then promote coupling sleeve and make positive flywheel (establish it and be the flywheel of left end) be in the position that can drive the outer spline disc of the splined of living with it by inner spline housing, like this, motive power will be passed through power shaft, connect kink, coupling sleeve, (centring ring), positive flywheel, inner spline housing, outer spline disc passes to output shaft output, corresponding pedal-type fitness bicycle just changeed and advanced this moment, when motive power disappeared, pedal-type fitness bicycle can advance according to inertia but can not make step idle running; Otherwise then pedal-type fitness bicycle counter-rotating retreats: when shift fork mediates, and the corresponding inner spline housing cavity of outer spline disc place, this moment, power can't transmit, and can not advance also can not retreat, and this is a neutral gear.
Therefore the utlity model has the advantage that the step that has neutral gear and can make pedal-type fitness bicycle is not dallied.
Below in conjunction with description of drawings most preferred embodiment of the present utility model:
Fig. 1 is a structural representation of the present utility model.
