Background technology
There is the hydraulic booster of part special purpose on the market at present, the mesh of power-assisted is generally reached using single hydraulic jack
's.To provide force feedback for pedal or handle, affected personnel are difficult to grasp operation for major defect performance.Single hydraulic oil
Cylinder can only provide original position and final position, it is impossible to stop in optional position in the middle of realizing, such as clutch cannot realize half
Linkage clutch, if brake, it is impossible to provide different braking strengths according to the size of pedal strength.Particularly once because of machinery
When failure loses oil pressure, plant equipment would be at stuck state, easily cause serious consequence.
Utility model content
This utility model purpose is to provide for a kind of novel hydraulic booster for solving above-mentioned technological deficiency.
To achieve these goals, this utility model is employed the following technical solutions：A kind of hydraulic booster, including cylinder body two
End is provided with the oil cylinder of oil-in and oil-out, and slidable fit has piston rod in the oil cylinder, on the periphery wall of the piston rod
Sealing is arranged with piston, and the oil cylinder is stretched out at the two ends of the piston rod, and the right-hand member of the piston rod is cylindrical in shape structure, the cylinder
The cylinder base fabric that slidable fit has push rod, the tubular structure in shape structure is provided with oil outlet, and the oil outlet connects the piston
Bar outer wall, offers the fuel feed hole for connecting the piston rod outer wall, the fuel feed hole and institute on the medial wall of the tubular structure
Left side and right side that oil outlet is successively set on the piston are stated, the fuel feed hole and the oil-in are located at the same of the piston
Side, the oil outlet is blocked when the push rod is contacted with the cylinder bottom of the tubular structure.
Preferably, pressure is provided with stage clip between the drum head of the push rod and the tubular structure.
Preferably, sealing ring is provided between the medial wall of the push rod and the tubular structure, the sealing ring is located at
The port of export of the tubular structure.
Preferably, the fuel feed hole is located at the friendship of the perforate positioned at the piston and the piston rod of the piston rod outer wall
At boundary.
In the state of hydraulic booster is not used, the periphery wall of the piston blocks the oil-in.
This utility model by by piston rod connect clutch control-rod, push rod connection clutch pedal, push rod with
Foot steps on envelope and sets the oil outlet, and now oil cylinder is divided into the two disconnected cavity volumes in left and right by the piston, the oil-in on right side
Hydraulic oil promotes piston to left movement, promotes the control-rod of clutch, clutch to be in clutch state, reach the effect of power-assisted；
When clutch pedal is unclamped, oil outlet is opened, then the cavity volumes connection of left and right two, then the pressure balance of side face of piston ring, from
Under the elastic force effect of clutch control-rod, piston return, clutch returns non-clutch state.When hydraulic system goes wrong, push rod
Directly the motion of clutch pedal can be transferred to into clutch control lever, realization is controlled under non helping hand state to clutch
System, it is to avoid stuck situation, same this utility model is equally applicable to brake or other need the mechanism of power-assisted.
This utility model has power-assisted effect good, prevents hydraulic system from ging wrong appearance that is stuck and causing dangerous situation,
Effectively, low cost effect is good, with very big use value for simple structure.
Description of the drawings
Fig. 1 is the structural representation of this utility model embodiment.
Specific embodiment
The technical solution of the utility model is further elaborated with reference to specific embodiment.
A kind of embodiment of hydraulic booster as depicted, including cylinder body two ends are provided with oil-in 5 and oil-out 3
Oil cylinder 2, the periphery wall upper sleeve gasket that slidable fit has piston rod 1, the piston rod 1 in the oil cylinder 2 is provided with piston 4, described
The oil cylinder 2 is stretched out at the two ends of piston rod 1, and piston rod left end connects the controller of clutch, and clutch is prior art, in figure
In be not drawn into, the right-hand member of the piston rod 1 is cylindrical in shape structure, and slidable fit has a push rod 6 in the tubular structure, the tubular knot
The cylinder base fabric of structure is provided with the cavity volume of oil outlet 10, the connection tubular structure of oil outlet 10 and the left side of piston 4, the medial wall of tubular structure
On offer the fuel feed hole 9 for connecting the piston rod outer wall, the cavity volume on the right side of the connection piston of the fuel feed hole 9, fuel feed hole 9 is arranged
In piston 4 and the intersection of push rod 6, the left end of the push rod 6 matches with the cylinder bottom structure of the tubular structure, when push rod 6
Left end when being pressed on the cylinder bottom of tubular structure, oil outlet 10 is sealed up by push rod, the drum head of the push rod 6 and the tubular structure
Between pressure be provided with stage clip 8, the right-hand member connection clutch pedal 7 of push rod 6 sets between push rod 6 and the medial wall of the tubular structure
Sealing ring is equipped with, the sealing ring is located at the port of export of the tubular structure, and under initial condition, i.e., booster does not play power-assisted
In the state of effect, piston 4 is located at low order end, blocks oil-in 5.
Main force's principle of this utility model embodiment is as follows：The control-rod of clutch is connected by the left end by piston rod 1,
The connection clutch of push rod 6 pedal 7, push rod 7 steps on envelope and sets the oil outlet 10 with foot, and now oil cylinder 2 is divided into a left side by the piston 4
Right two disconnected cavity volumes, the hydraulic oil of the oil-in 5 on right side promotes piston 4 and piston rod 1 to left movement, promotes clutch
Control-rod, clutch be in clutch state, reach the effect of power-assisted；When unclamping clutch pedal 7, stage clip 8 is by the bullet of push rod 6
Rise, oil outlet 10 is opened, then the cavity volume connection of left and right two, then the pressure balance of the both ends of the surface of piston 4, in clutch control lever
Under elastic force effect, piston return, clutch returns non-clutch state.When hydraulic system goes wrong, push rod 6 can directly by clutch
The motion of pedal 7 is transferred to clutch control lever, and realization is controlled under non helping hand state to clutch, it is to avoid stuck
Situation.
The present embodiment is illustrated for vehicle clutch, but this booster be not limited solely to it is clutch power-assisted,
Brake power-assisted or other forms need the mechanism of hydraulic booster equally applicable.
NM technology is prior art in this utility model.
It should be noted that optimum embodiment of the present embodiment for technical solutions of the utility model, when being not to this reality
With the further restriction of new claim, any deterioration or equivalents all should belong to the guarantor of this utility model claim
Within shield scope.
