Abstract
The utility model relates to a hydraulic-drive stepless speed reducer, belonging to the technical field of the design and the manufacture of speed changers. The utility model is composed of a power source and a controlling part, wherein, the power source is formed by that an output port of a hydraulic pump, an accumulator, a pipeline of a hydraulic motor; the controlling part is formed by that a controlling valve and an overflow valve are arranged on an input and an output pipelines of the hydraulic motor; a starting and stopping valve is arranged on an input duct of the hydraulic motor; the output pipes of each valve and the input duct of a pump are connected to an oil tank. The utility model has the advantages of favorable power performance, self lubrication, less abrasion, high reaction speed of operation but no impact, noise and pollution, saving the power source; one speed changer can provide power for more than two executing systems; the utility model can be applied to manpower vehicles, small-size motor vehicles and the devices of farm machinery.
Description
The utility model belongs to the design and fabrication technology field of the speed changer that is used on rickshaw, mini motor vehicle and the agricultural equipment.
At present, the electric gear shift(ing) of common use is the transmission working portion to be carried out speed governing change, and when running into big resistance, low-speed big can make vehicle wheel rotational speed slack-off, and tractive force increases; Otherwise, when resistance force diminishes, vehicle wheel rotational speed is accelerated, tractive force reduces.But also exist many problems, its volume is bigger, the electricity consumption loss of energy, and operation inconvenience, fault is more, not easy-maintaining.
The purpose of this utility model provides a kind of reduction of speed and increases and turn round or fall the stepless speed changing with hydraulic transmission device of turning round speedup.
The purpose of this utility model is to realize like this, constitute by power source and controlling component, power source is that the oil hydraulic pump delivery outlet is connected with accumulator, hydraulic motor lines, controlling component is cartridge control valve and a relief valve on the oil hydraulic motor input and output channel, two valves constitute the volumetric speed control valve, on the oil hydraulic motor input pipeline, also have the start-stop valve, safety valve and one-way valve and pressure gauge are housed on the oil hydraulic pump output pipe.Control valve, relief valve and safety valve output tube and oil hydraulic pump supplying tube all pass to fuel tank.
During use, hydraulic pump works, the accumulator accumulation of energy by start-stop valve and the control of volumetric speed control valve, makes oil hydraulic motor reach job requirement, realizes the utility model purpose.
The utility model has the advantages that rational in infrastructure, volume is little, power performance is good, saves power source, and a speed changer can provide power to two above executive systems, and can realize shaking control.There are not impact, noise and pollution; The energy self-lubrication, it is little to wear and tear; Operant response speed is fast; Overload protection is arranged, be convenient to maintenance.
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing is the utility model general assembly structural representation
This speed changer is made of power source and controlling component, power source is oil hydraulic pump (3) delivery outlet and accumulator (6), oil hydraulic motor (8) pipeline connects, controlling component is cartridge control valve on the oil hydraulic motor input and output channel (10) and relief valve (9), two valves constitute the volumetric speed control valve, start-stop valve (11) also is housed on the oil hydraulic motor input pipeline, safety valve (5) and one-way valve (4) and pressure gauge (7) are housed on the oil hydraulic pump output pipe, control valve, relief valve and safety valve output tube and oil hydraulic pump supplying tube all pass to fuel tank (1), and filter screen (2) is housed on the oil hydraulic pump supplying tube.
During use, this speed changer is contained on the bicycle, hydraulic motor output shaft directly links to each other with the bicycle live axle, oil hydraulic pump adopts the manpower oil hydraulic pump, drive oil hydraulic pump, accumulator holds oil, supplies Ji by start-stop valve and volumetric speed control valve control oil mass, make oil hydraulic motor reach service condition, thus the walking of control bicycle.This speed changer also can be applicable to other rickshaw, on mini motor vehicle and the agricultural equipment, can guarantee that these vehicles and equipment normally move.
