Abstract
A clutch cylinder for the electrically controlled mechanical speed variator of car is composed of a cylinder body with oil inlet and outlet holes and internal cavity having an annular step shape, short front diameter and longer back diameter, the front and back cylinders with different internal and external diameters and respectively inlaid in said internal cavity of cylinder body, two oil seals between the front and back cylinders and the inner surface of cylinder body, a hollow piston with small front end, big back end and several slots, the front and back oil seals in said slots for said front and back cylinders, and a spring on the piston and with a front end linked with a pull string of clutch separator.
Description
Technical field:
The present invention relates to a kind of oil cylinder, the clutch oil cylinder that particularly a kind of automobile electric control mechanical type speed variator is used.
Background technique
At present, the control of automobile electric control mechanical type speed variator clutch all is to adopt Electric Machine Control or hydraulic control basically.The Electric Machine Control poor reliability, its transmission generally needs leading screw and guide rail, and it is bigger to wear and tear, and lubrication effect is bad.Hydraulic control is very high to the oil cylinder requirement on machining accuracy, and poor sealing solves, the structure more complicated.
Summary of the invention:
Technical problem to be solved by this invention is: a kind of hydraulic control reliability height is provided, and simple in structure, the clutch oil cylinder that is easy to process.Its technological scheme is: the cylinder body inner chamber is stepped ringwise, and front inner diameter is less than back end inside diameter; The forward and backward oil cylinder in different inside and outside footpaths is bumped into respectively on the ring ladder of cylinder body inner chamber, between forward and backward oil cylinder and the cylinder body inwall by oil sealing sealing; Piston is a hollow structure, and the inside and outside footpath of its front end all less than inside and outside footpath, rear end, is scalariform, and the front and back ends of piston is equipped with groove, is provided with the forward and backward oil sealing that cooperates with forward and backward oil cylinder inner wall in the groove; Pocketed springs on the outer rim of piston, the front end of piston connects with the backguy that is connected clutch release assembly; Cylinder body be provided with fuel feeding into and out of oilhole.
The surface of described forward and backward oil cylinder is a roughened surface.
In-oil cylinder piston outer rim is provided with spring seat before described.
Described cylinder body is provided with pressure relief vent.
Compared with prior art, its technique effect is: because forward and backward oil cylinder adopts disassembly-type, segmented, stepped composite structure, and the surface of forward and backward oil cylinder is roughened surface, so both be convenient to make processing, be easy to dismounting again and keep in repair; The mode that adopts spring to cooperate with piston, made full use of the elasticity function of spring, under the dual reaction of spring and hydraulic oil, realized that piston seesaws in-oil cylinder, thereby drive the quick separation and the slowly combination of clutch, hydraulic control reliability height; Adopt the hollow type piston, be convenient on the one hand and the combining of backguy, be convenient to again on the other hand and being connected of sensor.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
As shown in Figure 1, oil cylinder of the present invention and cylinder body 8 are not one.The cylinder body inner chamber is stepped ringwise, and front inner diameter is less than back end inside diameter.Oil cylinder 1 and back oil cylinder 2 before oil cylinder is divided into, the inside and outside footpath of the two is all inequality, is made by steel pipe respectively, and its surface roughness is very high.Before oil cylinder inside and outside footpath all less than the back oil cylinder inside and outside footpath.The forward and backward oil cylinder in different inside and outside footpaths is bumped into respectively on the ring ladder of cylinder body inner chamber, is sealed by oil sealing 12,13 between forward and backward oil cylinder and the cylinder body inwall.Piston 3 is a hollow structure, and the inside and outside footpath of its front end all less than inside and outside footpath, rear end, is scalariform, and the front and back ends of piston 3 is equipped with groove, is provided with the forward and backward oil sealing 4,5 that cooperates with forward and backward oil cylinder inner wall in the groove.Pocketed springs 7 on the outer rim of piston, and preceding in-oil cylinder piston outer rim is provided with spring seat 11.Cylinder body be provided with fuel feeding into and out of oilhole 9, the loading by hydraulic oil can realize separating and combination of clutch with unloading.For the ease of when oil cylinder is out of control, the oil pressure in can unloading cylinder also is provided with pressure relief vent 10 on the cylinder body.Oil cylinder under normal circumstances, pressure relief vent is in sealed condition.The front end of piston connects with the backguy 6 that is connected clutch release assembly.Backguy, piston and spring can be realized the parallel feeding of rectilinear direction and fall back under the effect of hydraulic oil.Piston rear end links to each other with sensor, to measure the amount of exercise of backguy.
Its working principle: connect the backguy 6 of clutch release assembly, under the effect of clutch diaphragm spring, by clutch release assembly with backguy to the Zola, pressure spring 7 drives pistons 3 and moves right with backguy, makes backguy be in the tension working state.When hydraulic oil enters oil closed cavity through oil-through hole 9, hydraulic oil acts on piston 3 rear ends, and piston is moved right, and under the double action of holddown spring 7 and hydraulic oil, drives backguy and moves right, thereby realize the quick separation of clutch.When hydraulic oil when oil-through hole 9 is discharged oil closed cavities, under the return effect of clutch matrix spring, be moved to the left by clutch release assembly drive backguy and piston, under the dual reaction of holddown spring and hydraulic oil, can realize the slow combination of clutch.
