Description
Technical field
A kind of chain wheel is the utility model is related to, more particularly to a kind of belt pulley type endless chain transmission for bicycle, belongs to bicycle zero
Part.
Background technology
The power output system of bicycle includes：Chain wheel, pedal, chain, flywheel and trailing wheel, trailing wheel are mutually solid with flywheel
Fixed, chain connects flywheel and chain wheel, fixes pedal on chain wheel, user rotates chain wheel by pedal, and chain wheel is in chain
Drive under make flywheel turns, flywheel drives rear wheel, and when flywheel does not rotate, trailing wheel can still follow inertia to be rotated further.
Because the connection of chain wheel and vehicle frame is only fixed and rotated by a less axle portion of diameter, axle portion connection is stepped on
Plate, user's pedal drive axle portion to rotate, and then are rotated with movable chain wheel.But over time, axle portion can get rusty and
Fragility is raised, and when user exerts oneself pushes pedals, the axle portion for easily causing chain wheel is broken, and causes power output system report
It is useless, while got rusty additionally, due to the junction of chain wheel and axle portion, cause chain wheel to be not easy to take out, the replacing of chain wheel is inconvenient, and
And with sleet sky easily splashes water and silt, practicality is relatively low.
Utility model content
The purpose of this utility model is：A kind of belt pulley type endless chain transmission for bicycle that can solve problems described above is provided,
Can in riding effective draining and silt.
To achieve these goals, the utility model provides following technical scheme：
A kind of belt pulley type endless chain transmission for bicycle, including chain wheel body and it is arranged on chain wheel originally multiple tooth groups in vitro, the tooth
Disk body central is provided with a mounting hole, and the chain wheel body is connected with crank by connector, the connector end set
There is the dentalation being engaged with installation hole end surface, the chain wheel body both sides are provided with plate washer, and the tooth group is vertical by one
Downward gear piece and a gear piece composition straight up, the gear piece bottom is inwardly provided with slope, the chain wheel body one
Multiple support members are provided with the inside of side.
Preferably, the tooth group annular array sets chain wheel sheet external.
Preferably, the slope side is camber line, central angle corresponding to the camber line is no more than 15 °.
Preferably, the support member and crank are located at the same side of chain wheel body.
Preferably, the length of the connector is more than the height of mounting hole.
The beneficial effects of the utility model are：This belt pulley type endless chain transmission for bicycle is simple in construction, practical, and both sides are all
Prevent belt dropping plate washer, the slope set by gear piece bottom, can in riding effective draining and silt；When reduction is ridden
Difficulty, frictional resistance when riding more is reduction of, so as to reduce the abrasion of part.
Brief description of the drawings
Fig. 1 is a kind of front view of belt pulley type endless chain transmission for bicycle of the utility model；
Fig. 2 is the assembling assumption diagram of the utility model chain wheel body；
Fig. 3 is the rearview of the utility model chain wheel body.
The mark of each part of accompanying drawing is as follows：1st, chain wheel body；2nd, gear piece；3rd, connector；4th, crank；5th, plate washer；6th, slope；
7th, support member.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
Referring to figs. 1 to shown in Fig. 3, a kind of belt pulley type endless chain transmission for bicycle, including chain wheel body 1 and it is arranged on chain wheel body
Multiple tooth groups outside 1, the chain wheel body 1 are provided centrally with a mounting hole, and the chain wheel body 1 passes through the phase of connector 3 with crank 4
Even, the end set of connector 3 has the dentalation being engaged with installation hole end surface, and the both sides of chain wheel body 1 are provided with
Plate washer 5, the tooth group are made up of a gear piece 2 and a gear piece 2 straight up straight down, the bottom of gear piece 2 to
Slope 6 is inside provided with, multiple support members 7 are provided with the inside of the side of chain wheel body 1 one.
Further, the tooth group annular array is set outside chain wheel body 1.
Further, in order to which effective draining and silt in riding, the side of slope 6 are camber line, the camber line is corresponding
Central angle be no more than 15 °.
Further, in order to increase the service life of chain wheel, the support member 7 and crank 4 are located at the same of chain wheel body 1
Side.
Further, in order to which rapidly crank 4 and chain wheel body 1 are assembled, the length of the connector 3 is more than peace
Fill the height in hole.
This belt pulley type endless chain transmission for bicycle is simple in construction, practical, and both sides prevent belt dropping plate washer, pass through
Gear piece bottom set slope, can in riding effective draining and silt；Difficulty when riding is reduced, is more reduction of when riding
Frictional resistance, so as to reduce the abrasion of part.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
