Abstract
The utility model relates to a hydraulic transmission device of a bicycle, which is composed of a driving wheel, a driven wheel and a manual commutator. A rotor and a stator are arranged in the driving wheel of the utility model and the driven wheel of the utility model; the driving wheel is connected with the driven wheel through an oil pipeline; lubricant grease is filled in an entire sealing system. The utility model can make a rotor of the driving wheel rotate under the action of external force; a rotor of the driven wheel can be made to rotate through the pressure transmission of an oil column, and therefore, a bicycle can be ridden; because the utility model overcomes the defects of abrasion, broken chains, groove jump, etc. of chain transmission in the prior art, the utility model can be widely used for the power transmission of bicycles.
Description
The utility model belongs to torque transfer and is particularly related to a kind of hydraulic actuator that is used for bicycle.
At present, the driving system of bicycle adopts the chain drive mode to move more, this vehicle have solved the difficulty of people's walkings, because simply being convenient to keep in repair bring great convenience to the user, the bicycle structure in the existing technology becomes a kind of vehicle that people like, but because there is following several aspects shortcoming in the transmission adopted chain gear of bicycle:
1. because the squareness and the parallelism of chain wheel and chain are had relatively high expectations, it is difficult to add man-hour.
2. bicycle is in operation and causes the chain elongation, and occurring chain and sprocket wheel easily can not use in the correct engagement influence.
3. chain is job-hoped easily and is influenced stabilizer for bicycle and travel when being in high-speed operation.
Because chain transmission mode exists above shortcoming that the superior functionality of bicycle is not brought into play, a kind of bicycle that utilizes hydraulic transmission mode to be used as power is not reported so far.
The purpose of this utility model is a kind of mechanical drive deficiency and stable drive of remedying of design-calculated in order to overcome above-mentioned shortcoming, and load-carrying capacity is big, realizes infinite variable speed hydrostatic drive bicycle again easily.
The utility model is to realize like this.
The utility model is divided into driving wheel and flower wheel and manual pulley, direction reverser three parts.Wherein, driving wheel is installed in the middle shaft position of existing technology bicycle, flower wheel is contained in wheel location behind the car body, hand change over valve is fixed on above the back boom support of bicycle, during use, foot-operated axis wheel disc makes the rotor of driving wheel stir fluid, flow into the flower wheel from oil-piping, force the rotor in the flower wheel to drive the bicycle running, when the needs total system shuts down, can move hand change over valve to midway location, (dotted line position among Fig. 2) this moment, the oil circuit in the pipeline disconnected, driving wheel, fluid in the flower wheel is stopping circulation in the system separately, and the power hydraulic system of bicycle will not play the power-assisted effect.
Advantage of the present utility model:
Because transmission device has adopted power hydraulic system, the job-hopping and the disconnected strip defect that easily cause elongation or bring because of wearing and tearing because of chain gear have been overcome in the existing technology, use this driving system can realize that the power of bicycle steadily transmits, alleviate manual labor, can realize the stepless change of bicycle again, increase the load-carrying capacity of car body self.
The utility model is provided by following examples.
Be illustrated below in conjunction with accompanying drawing:
Accompanying drawing: 1. hydraulic transmission gear for bicycle structural representation.
2. hydraulic transmission gear for bicycle link system scheme drawing.
3. hydraulic transmission gear for bicycle structure A-A is to generalized section
The utility model is by a kind of hydraulic actuator that is installed on bicycle middle shaft and the rear wheel support, be by flower wheel 18, driving wheel 19 and manual reverse of direction device 17 are formed, it is characterized in that connecting together with oil circuit pipeline 21 between the described driving wheel, a seal stator end cap 2 and rotor seal end cap 9 are arranged in driving wheel and the flower wheel, be provided with rotor 1 and stator 4 therebetween, stator is fixing with bolt and end cover 2, rotor 1 connects mutually with antifriction-bearing box 7, lateral surface at rotor seal lid 9 is equipped with seal disc 6 and sealing shroud 13, this device also includes stator " O " RunddichtringO 10 in addition, seal stator end cap fixed bolt hole 11, rotor " O " RunddichtringO 12, rotor seal ring gland 14 parts such as grade, during by dress, before this rotor 1 was put into stator 4, rotor, stator connects by antifriction-bearing box 7, the sealing of rotor is to rely on the seal disc 6 and the sealing shroud 13 that are fixed on rotor seal end cap lateral surface to realize, a seal disc 6 is arranged in the outside of sealing shroud 13 and will adjust sealing shroud and be pressed into above the seal stator end cap 2, antifriction-bearing box 8 is put on the bearing groove of seal stator end cap 2 and seal disc 6 by bearing lubrication hole 5, and then fix with gland and screw, rotor seal end cap 9 and rotor seal ring gland 14 are fixed by bolts on the seal disc.
Flower wheel is in the same place by key and output shaft coupling with driving wheel, in addition driven, also have oil inlet 15 above the driving wheel and connect with oil outlet 16 and with oil circuit pipeline 21.By the break-make that the manual reverse of direction device is regulated the two-wheeled oil circuit, the sealed hydraulic driving device is full of lubricating grease in the whole chamber in working order the time.
Claims (3)
1, a kind of hydraulic actuator that is used for bicycle is by flower wheel 18, and driving wheel 19 and manual reverse of direction device are formed, and it is characterized in that described driving wheel, are bound up with oil circuit pipeline 21 between the flower wheel.
2, according to the described hydraulic transmission gear for bicycle of claim 1, it is characterized in that a seal stator end cap 2 and rotor seal end cap 9 are arranged in described driving wheel and the flower wheel, be provided with rotor 1 and stator 4 therebetween, stator is fixing with bolt and end cover 2, rotor 1 is connected with antifriction-bearing box 7, at the lateral surface of rotor seal end cap 9 seal disc 6 and sealing shroud 13 is housed.
