Abstract
The utility model relates to a tricycle chain wheel speed changer, and a driving shaft and a driven shaft are arranged in a box body. One end of the driving shaft, which is outside the box body, is fixedly provided with a driving wheel, and an engaging and disengaging driving chain wheel at a high speed, an engaging and disengaging driving chain wheel at a medium speed and a normal down shifting driving chain wheel are arranged on the driving shaft in the box body in turn. One end of the corresponding driven shaft, which is outside the outer box, is fixedly provided with a driven wheel, and an engaging and disengaging driven chain wheel at a high speed and an engaging and disengaging driven chain wheel at a medium speed are sheathed on the driven shaft in the box body. The utility model has the characteristics of compact and reasonable design, extensive application, reliable drive, flexible operation, multiple speeds, convenient shift, etc. The application of the utility model can increase transportation weight and overcome the impact on transportation by the road grade size. Therefore, the utility model is an ideal appliance for a tricycle or other bicycles to improve efficiency and save labor.
Description
Affiliated field: the utility model relates to a kind of three-wheel vehicle sprocket transmission.
Background technology: present manpower three-wheel seldom has transmission system, and the each gearshift of some transmission system all will be stopped and be stirred chain shift with hand, and transmission device is loaded down with trivial details, is exposed to the outside and gets rusty easily, and uses maintenance all inconvenient.
Summary of the invention: the purpose of this utility model provides a kind of can the variation and high, normal, basic multiple speed, flexible operation, the three-wheel vehicle sprocket transmission easily of shifting gears.The purpose of this utility model realizes by following structure: the utility model is a kind of three-wheel vehicle sprocket transmission, an imput shaft and a velamen moving axis are installed in the casing, the end of imput shaft outside casing installs and fixes driving wheel, but the clutch of fixed installation high speed successively drive sprocket on the main shaft in casing, but middling speed clutch drive sprocket, normal down shifting drive sprocket, the end of relative driven axle outside casing installs and fixes follower, but on the driven axle in casing successively suit at a high speed clutch by movable sprocket, but the middling speed clutch is by movable sprocket, fixedly mount normal down shifting by movable sprocket, drive sprocket with all adopted chain to be connected between the movable sprocket, the gear pull bar is connected with the variable block steady arm by a connecting rod mechanism, the variable block steady arm is sleeved on the driven axle, but clutch is by movable sprocket at a high speed, but the passive sprocket shaft of middling speed clutch is to being positioned, the variable block steady arm slides vertically, radially rotates to be fixed.But but high speed clutch of the present utility model is idle running by movable sprocket, middling speed clutch at ordinary times by movable sprocket, after stirring the gear pull bar, make again the speed change position retaining device with the two one of is connected, the generation effect of putting into gear, often putting into gear at ordinary times is low gear position.Being to adopt the characteristic of flywheel reverse portion work with the utility model innovation part, be installed in the very little casing by big small flywheel is ingenious, conversion mutually reaches in that chain is in service and plays chronotropic action.The utility model characteristics are compactnesses reasonable in design, and purposes is wide, and reliable transmission can change and high, normal, basic multiple speed, flexible operation, and gearshift is convenient etc.Application of the present utility model can improve domestic shipping weight and overcome the influence of road grade size to transportation.Be that three-wheel and other bicycle are raised the efficiency, save the desirable utensil of manpower.The utility model can be installed in the position that does not influence other acting within the chain arbitrarily, is easy to maintenance and inspection, and it is convenient to change parts, and a lot of waste and old accessories can be reused, be economizing type, environment-friendly type, rational exploitation and utilization human body manpower.
Description of drawings:
