Abstract
The utility model relates to a hydraulic motor of a bicycle. The utility model relates to a hydraulic element, particularly a hydraulic motor used on a boosted vehicle, or a bicycle, or a tricycle. The utility model needs to solve the technical problem that the utility model provides a hydraulic motor which is suitable for vehicles of the class of small motor and non-motor vehicles. The utility model has the technical scheme that the utility model adopts a casing rotating type double shaft outlet hydraulic motor which is composed of oil matching shafts, an oil inlet ring, an oil outlet ring, a cam stator, a rolling body, a plunger, a rotor and a casing. The utility model is characterized in that the radial outer edge of the casing of the hydraulic motor is connected with a disk chuck; The end parts of the oil matching shafts at the outer sides of the left and right oil inlet and outlet rings of the hydraulic motor are respectively provided with a shaft end screw thread. The utility model is suitable for vehicles of the class of small motor and non-motor vehicles.
Description
Technical field
The utility model relates to hydraulic element, the oil hydraulic motor of using in particular for equipment of small motor and the bicycle class traffic tool such as motor-helping car or bicycle, tricycle.
Background technique
At present, the motor low-speed performance that motor-helping car is used is bad, and also owing to limit by power capacity, output torque is less, and the ability of resisting rugged environment is relatively poor, needs to give the relevant equipment of motor-helping car that more selection is provided.The application of hydraulics in industry now is increasingly extensive, and the good airproof performance of oil hydraulic motor relatively is competent at the work in rugged environment.The shell-rotating type oil hydraulic motor of forming by oil distributing shaft, turnover oil ring, cam stator, rolling element, plunger, rotor, housing, the direction of action that comprises rolling element is the oil hydraulic motor of dual mode axially or radially, as carries out corresponding transformation and then can adopt for Bicycle.
The model utility content
The utility model technical issues that need to address provide a kind of oil hydraulic motor that equipment of small motor and the bicycle class traffic tool such as motor-helping car or bicycle, tricycle are used that is suitable for.
The technical solution of the utility model adopts the two shaft oil hydraulic motors of being made up of oil distributing shaft, turnover oil ring, cam stator, rolling element, plunger, rotor, housing of shell-rotating type, the radially outer that it is characterized in that the oil hydraulic motor housing has floral disc, and the oil distributing shaft end in the turnover oil ring outside is shaped on the axle head screw thread about oil hydraulic motor.
The utility model is owing to adopt the two shaft oil hydraulic motors of shell-rotating type, characteristics with low-speed big, and when the pressure oil fuel cut-off and return tube fully during off-load, the housing that rotor dragged can free running down, function just as bicycle freewheel, because the oil hydraulic motor good airproof performance can be at dust, moist rugged environment even underwater operation; Oil hydraulic motor housing radially outer is connected with floral disc, possesses the wheel hub structure that is arranged on the bicycle quick center, and simultaneously, the oil distributing shaft end in the turnover oil ring outside is shaped on the axle head screw thread about oil hydraulic motor, is suitable for the requirement that the adapted nut is directly installed at frame fork.
Description of drawings
That accompanying drawing is represented is hydraulic motor structure figure of the present utility model.
Embodiment
Implement concrete mode of the present utility model below in conjunction with description of drawings: the utility model adopts by oil distributing shaft 1, turnover oil ring 8, cam stator 2, rolling element 3, plunger 4, rotor 5, housing and comprises the two shaft oil hydraulic motors of shell-rotating type that shell 6 and cover plate 7 are formed; The utility model can adopt radial ball piston motor or axial bulb stopper motor, and axially bulb stopper motor radial dimension specific diameter is little to the bulb stopper motor, is more suitable for the installation conditions of bicycle; Be to reduce the deadweight of oil hydraulic motor, can establish in the cross section gabarit of the rotor 5 of oil hydraulic motor and alleviate groove to reduce the deadweight of rotor, rotor alleviates groove and is located between the oilhole, alleviates groove and can adopt arc or horn shape groove; Oil hydraulic motor housing radially outer is established the wheel hub that floral disc becomes the installation wheel spoke; The oil hydraulic motor housing 6 radially floral disc of outer can be located on the shell 6, also can be located at the outer of cover plate 7; Oil distributing shaft 1 is a jack shaft of supporting oil hydraulic motor, and oil distributing shaft 1 end in turnover oil ring 8 outsides is shaped on the axle head screw thread and can be used as wheel shaft on the frame fork about oil hydraulic motor, mixes nut and directly installs on frame fork.
