Abstract
The utility model relates to a kind of bicycle, particularly relate to a kind of rear axle crotch centering type snow bicycle, sprocket wheel rear flank yoke frame is greater than sprocket wheel offside rear axle crotch apart from car body distance between center line apart from car body distance between center line, sprocket wheel rear flank wheel spoke length correspondence is longer than sprocket wheel offside trailing wheel spoke length, and trailing wheel circumferential line overlaps with car body line of centers.When car body and circumferential line constant, increase the distance of sprocket wheel side chain wheel and tire tread, actv. prevents sprocket wheel and tire friction.
Description
Technical field
The utility model relates to a kind of bicycle, particularly relates to a kind of rear axle crotch centering type snow bicycle.
Background technology
Snow bicycle is the bicycle that a kind of tire tread is larger, and can ensure provides larger friction force on snowfield, and larger tyre surface and change-speed box, easily cause the plane run-off the straight at sprocket wheel place, and rub with tire.
Utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of rear axle crotch centering type snow bicycle preventing sprocket wheel and tire from rubbing.
The utility model is achieved by the following technical programs:
A kind of rear axle crotch centering type snow bicycle, sprocket wheel rear flank yoke frame is greater than sprocket wheel offside rear axle crotch apart from car body distance between center line apart from car body distance between center line, sprocket wheel rear flank wheel spoke length correspondence is longer than sprocket wheel offside trailing wheel spoke length, and trailing wheel circumferential line overlaps with car body line of centers.
The beneficial effects of the utility model are:
Because sprocket wheel rear flank yoke frame is greater than sprocket wheel offside rear axle crotch apart from car body distance between center line apart from car body distance between center line, sprocket wheel rear flank wheel spoke length correspondence is longer than sprocket wheel offside trailing wheel spoke length, trailing wheel circumferential line overlaps with car body line of centers, when car body and circumferential line constant, increase the distance of sprocket wheel side chain wheel and tire tread, actv. prevents sprocket wheel and tire friction.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
In figure: 1. sprocket wheel rear flank wheel spoke length, 2. sprocket wheel offside trailing wheel spoke length, 3. car body line of centers, 4. sprocket wheel offside rear axle crotch is apart from car body distance between center line, and 5. yoke frame in sprocket wheel rear flank is apart from car body distance between center line, 6. trailing wheel circumferential line.
Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in Figure 1, the utility model sprocket wheel rear flank yoke frame is greater than sprocket wheel offside rear axle crotch apart from car body distance between center line 4 apart from car body distance between center line 5, sprocket wheel rear flank wheel spoke length 1 correspondence is longer than sprocket wheel offside trailing wheel spoke length 2, and trailing wheel circumferential line 6 overlaps with car body line of centers 3.
Because sprocket wheel rear flank yoke frame is greater than sprocket wheel offside rear axle crotch apart from car body distance between center line apart from car body distance between center line, sprocket wheel rear flank wheel spoke length correspondence is longer than sprocket wheel offside trailing wheel spoke length, trailing wheel circumferential line overlaps with car body line of centers, when car body and circumferential line constant, increase the distance of sprocket wheel side chain wheel and tire tread, actv. prevents sprocket wheel and tire friction.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
