Abstract
The utility model relates to a hydropneumatic clutch speed change device, which comprises a pump body, a drive shaft, a driven shaft, an eccentric shaft, a connecting rod, a plurality of plunger pistons, a control valve and a communicating pipe, and is characterized in that liquid or gas is used as the working medium and plays a role of clutch and transmission. Two groups of plunger pistons are arranged on the radial line in the pump body, and each group is communicated by a communicating pipe which is provided with a control valve; the eccentric shaft is arranged on the drive shaft to pull the connecting rod to drive the plunger pistons to work, and the driven shaft is connected with the pump body, liquid is positioned inside the pump body. The utility model has the advantages of simple structure, stable performance, security, trustiness and ruggedization, and is the optimal clutch, speed transmission and fully automatic stepless speed change device in traffic, transportation, industrial and mining enterprises.
Description
Technical field:
The utility model belongs to clutch speed variator, and is especially a kind of with liquid or the gas clutch speed variator as working medium.
Background technique:
Existing automobile-used clutch is a pressure plate type clutch, opens by platen and presses clutch-plate to play clutch action, all is that hard thing contacts with hard thing, and particularly wearing and tearing are faster under half-clutch state.Existing speed changer all is gear graduation or strap speed varying.Speed change all is step change, and the heavy operating conditions of equipment is restricted, abrasion or damage easily, and no clutch or synchronizer cooperate at all can't speed change.
Summary of the invention:
The purpose of this utility model is to provide a kind of simple in structure, stable performance, durable, with liquid or the gas clutch speed variator as working medium.
Technical solution of the present utility model is such, comprises by the pump housing, driving shaft, driven shaft, eccentric shaft, connecting rod, plunger, control valve, connecting tube, is characterized in liquid or gas making it play clutch, chronotropic action as working medium.On the radial line in the pump housing two groups of plungers are installed, every group of pump housing communicated with connecting tube, control valve was housed on connecting tube, driving shaft one end car has eccentric shaft, plunger connects connecting rod, the bearing block support driving shaft is equipped with in pump housing side, and the bearing block support driven shaft is equipped with in pump housing another side, filled with fluid or gas in the pump housing.
The utility model has the advantages that simple in structure, stable performance, safe and reliable, durable, as working medium, make it play clutch, chronotropic action with liquid or gas.Be traffic, transportation, the optimal clutch of industrial and mining enterprise, speed change and full-automatic stepless speed changes devices.
Description of drawings:
Fig. 1 looks sectional view for overall structure master of the present utility model.
Fig. 2 looks sectional view for the overall structure of the present utility model right side.
Fig. 3 is a pump housing three-dimensional view of the present utility model.
Among Fig. 1～Fig. 3, driving shaft (1), eccentric shaft (2), plug connecting rod (3), plunger (4), the pump housing (5), driven shaft (6), control valve (7), connecting tube (8), plunger connecting rod (9), bearing support (10), liquid (11).
Embodiment:
Most preferred embodiment of the present utility model is such, with reference to Fig. 1～shown in Figure 3, as working medium, makes it play the effect of clutch, speed change with liquid (12).Specifically: on the radial line in the pump housing (5) two groups of plungers (4) are installed, every group of pump housing (5) communicated with connecting tube (8), control valve (7) was housed on connecting tube (8), driving shaft (1) one end car has eccentric shaft (2), plunger (4) connects connecting rod (3), bearing support (10) supporting driving shaft (1) is equipped with in the pump housing (5) side, and bearing block support driven shaft (6) is equipped with in the pump housing (5) another side, interior filled with fluid of the pump housing (5) or gas (11).
The novel working principle of this reality is: when driving shaft (1) rotates, eccentric shaft (2) and then driving shaft (1) rotates and drivening rod (3), and the motion of connecting rod (3) two plunger (4) is promoting the interior liquid of the pump housing (5) or gas (11) discharged or sucks by connecting tube (8).Control valve (7) on connecting tube (8) opens, and torsionless was delivered to driven shaft (6) and plays centrifugation when driving shaft (1) rotated.When control valve (7) when closing, liquid (11) can not be arranged suction in the pump, and plunger (4) can not move, and makes the torsion of driving shaft (1) be delivered to driven shaft (6), thereby plays the effect of closing.By the control valve (7) in control connecting tube (8), can change the transmission volume of the liquid (11) in the pump, play driving shaft (1) rotating speed and be different from driven shaft (6), thereby play the stepless change effect.Control valve (7) in employing load control connecting tube (8) can be used as the super automatic stepless speed-changing device of ripple disable state.During transmission that driving shaft (1) is unpowered, by the control valve (7) on connecting tube (8) open or close play control driven shaft (6) static or the running.Also can be used as speed limiting device or braking device independently.
