Abstract
The utility model discloses an automatic shifting performer of a mechanical step variator, and the automatic shifting performer is vertically assembled by four double-piston single-action plunger cylinders. A small piston is positioned in a big piston, a piston rod and a deflector rod of the small piston are separately fastened and hinged. A cylinder cap is separately provided with fours pipelines (gas lines or oil lines) A, B, C and D, and the automatic shifting performer can realize the conversion of nine different shifts through changing the logic function of four pipelines. The automatic shifting performer has the advantages of simple structure, compactness and high reliability, and the automatic shifting performer is suitable for the machine tool with a mechanical step variator and medium-size and large-size automobile variators with a synchronizer and an atmospheric pressure source.
Description
The utility model relates to a kind of self shifter final controlling element of mechanical step change transmission.
Existing double acting cylinder gearshift final controlling element can only be realized the control of two stations, and multi-cylinder also can only be realized the control of three stations, and will just can be achieved with four controlling plumbing fixtures.(can referring to relevant mechanical design handbook).
The purpose of this utility model is to be easy to realize the gearshift final controlling element of control automatically for mechanical step change transmission design is a kind of.
Principle of the present utility model is that described final controlling element is made up of two pairs of single-action plunger piston cylinders and centering body; Every pair of centering body is made of a pair of big piston, a pair of small piston and piston rod; The small piston on piston rod top cooperates with the big piston that is positioned at cylinder is slick and sly, and big piston cooperates with slyness in the cylinder; Described cylinder is that cylinder body adds the cylinder cap structure; The integral structure characteristic of described final controlling element is that axisymmetric center line and another axisymmetric center line to the piston rod of single-action plunger piston cylinder and centering body of piston rod of a pair of single-action plunger piston cylinder and centering body is perpendicular, but non-intersect; The piston rod of one end of driving lever and described a pair of single-action plunger piston cylinder and centering body is hinged, and the middle-end of described driving lever and another piston rod to single-action plunger piston cylinder and centering body are fastened, referring to accompanying drawing 1 or 2.
Above-mentioned principle partly is described in further detail below.
The utility model utilizes the centering body mode, and A, B, C and four double-pistons of D (being that small piston is housed in the big piston) single-action plunger piston cylinder are arranged vertically, and the axisymmetric center line of C and D cylinder meets at the axisymmetric center line of A and B cylinder; Driving lever connects with A and B cylinder piston rod rigidity, and the peach shape arm of driving lever upper end A B cylinder piston rod and the arc groove of C and D cylinder piston rod are hinged.A, B, C and four control loops of D (gas circuit or liquid road) are housed on the cylinder cap of this final controlling element,, can realize the conversion of 9 different gears by changing the logical function in A, B, C and four loops of D.Accompanying drawing 3 is the logical function table of this final controlling element, and wherein " 0 " is exhaust (or oil return), and " 1 " is air inlet (or oil-feed).For example the logical function of 1 retaining is 0110, i.e. A and D cylinder exhaust (or oil return), and B and C air inlet (or oil-feed), all the other are by that analogy.
It is simple in structure, compact, reliable that advantage of the present utility model is, and can realize the mutual conversion of 9 different gears.
(1) cylinder cap (2) cylinder body (3) big piston (4) small piston (5) piston rod
(6) driving lever
Accompanying drawing 2 is gearshift final controlling element floor map;
(7) " 0 " RunddichtringO (8) cylinder liner (9) rubber cushion (10) driving lever
(11) body of rod (12) peach type arm (13) pin
Accompanying drawing 3 is gearshift final controlling element principle, gear and logical function figure.
Embodiment:
Accompanying drawing 2 has provided a specific embodiment of the utility model and the connection of east wind EQ140 type automotive transmission.As seen from Figure 2, the cast member that cylinder block (2) is structure as a whole, small piston (4) adopts the stationary fit mode fastening with piston rod (5) two ends, in the groove of big piston (3) and small piston (4) cylindrical side, " 0 " RunddichtringO is housed respectively, for making cylinder that good air tightness be arranged, between cylinder cap (1) and cylinder liner (8), rubber cushion (9) is housed.For making driving lever (6) be easy to processing and assembling, driving lever (6) is fastened on the piston rod (5) of A and B cylinder by the body of rod (11) and peach type arm (12) by pin, the piston rod of the spheroidal termination of described peach type arm (12) and C and B cylinder is hinged, and the fork (10) of stirring of the other end of the described body of rod (11) and speed changer links.
Gearshift actuator of the present utility model is suitable for the actuator of the self shifter control of lathe that machinery stepped transmission is housed and the medium-sized or above automobile pneumatic braking system speed changer that sychronisation arranged. Such as self shifter control of domestic east wind EQ140S5A etc.
Claims (1)
1, a kind of gearshift final controlling element, this final controlling element is made up of two pairs of single-action plunger piston cylinders and centering body, the small piston on the piston rod top of centering body is joined with the big piston slyness that is positioned at cylinder, slyness is joined in big piston and the cylinder, described cylinder is that cylinder body adds the cylinder cap structure, it is characterized in that right perpendicular of the axisymmetric center line of piston rod of a pair of single-action plunger piston cylinder of described final controlling element and centering body and another, and non-intersect; One end of driving lever is hinged mutually with the piston rod of described a pair of single-action plunger piston cylinder and centering body, and the middle-end of described driving lever and another piston rod to single-action plunger piston cylinder and centering body are fastened.
