Abstract
The utility model relates to a driving device for a bicycle, particularly a driving device which is capable of treading in a reverse direction and advancing in a positive direction, more specifically a bidirectional driver for the novel bicycle, which comprises a rear shaft, a chain wheel, a driving gear; a forward drive mechanism, a reverse drive mechanism and a gear cover, wherein the gear cover comprises a left gear cover and a right gear cover; the forward drive mechanism comprises the driving gear and a ratchet wheel; the reverse drive mechanism comprises a ratchet wheel which is connected outside a middle port by a left ratchet pawl and the driving gear, and a central gear which is arranged outside the back port of the ratchet wheel by the left ratchet pawl and the ratchet wheel. The utility model has the advantages of simple structure, convenient fabrication and uniform stress. After in use for some time, rack bars of a satellite gear wheel is not easy to deform. When the bicycle is treaded by feet in the reverse direction, walk and body-building are combined into integration. The bicycle is driven with moderate strength, and the pleasure of cycling is increased.
Description
Technical field
The utility model relates to a kind of bicycle drive, refers in particular to the oppositely just progressive driving device of treadmill, is specially the new bicycle bidirectional drive.
Background technology
The patent No. is that the structure that 98102392.4 name is called disclosed two-way drive device in the patent application document of " two-way double speed driver for bicycle " comprises that two ends are provided with the rear axle of coro bearng, be located at the sprocket wheel on the rear axle, with sprocket wheel bonded assembly drive gears, with drive gears bonded assembly forward drive mechanism, with the drive gears bonded assembly comprise sun gear, with rear axle bonded assembly planetary wheel carrier, be located on the planetary wheel carrier with sun gear by the tooth bar planet gear meshed, with the reverse driving mechanism of planetary wheel bonded assembly wheel hub, be located at the shelves lid of two-way drive device periphery; Driver train comprises forward drive mechanism and reverse driving mechanism.Sun gear and drive gears (right drive gears or Left Drive shelves) are connected as a single entity.Shelves are covered on the outside of left ratchet.The power transmission route of forward drive mechanism is: sprocket wheel → right drive gears → right ratchet → right ratchet → wheel hub, the power transmission route of reverse driving mechanism is: though the two-way drive device of sprocket wheel → right drive gears → sun gear → planetary wheel → internally toothed annulus → Left Drive shelves → left pawl → this structure of left ratchet → wheel hub can be realized bi-directional drive, but there is discontinuity, uses after a period of time defectives such as planetary tooth bar easy deformation.
Summary of the invention
The utility model provides a kind of new bicycle bidirectional drive in order to overcome the above-mentioned defective that existing bicycle two-way drive device exists.
The technical solution of the utility model realizes in the following way: a kind of new bicycle bidirectional drive, comprise that two ends are provided with the rear axle of coro bearng, be located at the sprocket wheel on the rear axle, with sprocket wheel bonded assembly drive gears, with drive gears bonded assembly forward drive mechanism, with the drive gears bonded assembly comprise sun gear, with rear axle bonded assembly planetary wheel carrier, be located on the planetary wheel carrier with sun gear by the tooth bar planet gear meshed, with the reverse driving mechanism of planetary wheel bonded assembly wheel hub, be located at the shelves lid of two-way drive device periphery; The shelves lid comprises left side shelves lid and the right shelves lid that interconnects and surround driver train; Forward drive mechanism comprise the outer ring by right ratchet be fixed in the drive gears that big right ratchet that right shelves cover is connected, be located in the transmission ring washer, be provided with in the front port be provided with in coro bearng groove and the groove coro bearng, the front port ratchet by right ratchet and drive gears bonded assembly outward; Reverse driving mechanism comprises the outer ratchet by left pawl and drive gears bonded assembly of middle port, the rear port of being located at ratchet outward pass through the sun gear that left pawl is connected with ratchet.When stepping forward when changeing before pedal makes sprocket wheel, sprocket wheel drives wheel and rotates forward by drive gears and big right ratchet and ratchet engaged; When stepping backward when changeing after pedal makes sprocket wheel, sprocket wheel is by drive gears and ratchet engaged, and drives sun gear by ratchet planetary wheel is rotated, thereby wheel is rotated equally forward.
The utility model is simple in structure, simple for production, compare with prior art, the utility model is stressed evenly, planetary tooth bar also is not easy distortion after using a period of time, oppositely during bicycle, have walking along the street and body-building concurrently in one, dynamics is moderate can be driven, and has increased the enjoyment of walking along the street by bike.

Fig. 1 is the utility model structural representation;
The specific embodiment
A kind of new bicycle bidirectional drive, comprise that two ends are provided with the rear axle 2 of coro bearng 1, be located at the sprocket wheel 3 on the rear axle, with sprocket wheel bonded assembly drive gears 4, with drive gears 4 bonded assembly forward drive mechanisms, with drive gears 4 bonded assemblys comprise sun gear 5, with rear axle 1 bonded assembly planetary wheel carrier 6, be located on the planetary wheel carrier 6 with sun gear 5 by tooth bar planet gear meshed 7, with the reverse driving mechanism of planetary wheel 7 bonded assembly wheel hubs 8, be located at the shelves lid of two-way drive device periphery; The shelves lid comprises left side shelves lid 9 and the right shelves lid 10 that interconnects and surround driver train; Forward drive mechanism comprises the outer ring by the drive gears 4 that right ratchet 11 is connected with big right ratchet 12 on being fixed in right shelves lid 10, be located in drive gears 4 circles, be provided with in the front port be provided with in coro bearng groove 13 and the groove coro bearng 1, the front port ratchet 14 by right ratchet 11 and drive gears 4 bonded assemblys outward; Reverse driving mechanism comprises middle port outward by left pawl 15 ratchet 14 with drive gears 4 bonded assemblys, be located at the rear port of ratchet 14 outer pass through the sun gear 5 that left pawl 15 is connected with ratchet 14.
Ratchet also can be connected with sun gear by left pawl from sidepiece.
In order to reduce friction, connecting box 16 can be set on rear axle, planetary wheel carrier 6 is arranged on the connecting box 16.Be that rear axle is provided with the connecting box 16 that is connected with planetary wheel carrier 6.
In order further to reduce friction, can on rear axle, coro bearng 1 be set the place, two ends of connecting box 16.
For the ease of dismounting and repairing,, transmission system can be removed also for the consideration on the cost.
