Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1,2, the fine motion selector valve of a kind of Non-follow control of the present invention, it combines primarily of commutation parts and fine motion controlling component two-part, described commutation parts are by valve body 2, pressure spring 3,4,5, large piston 9, small piston 6, spring 10 and steel ball 11 are formed individual event valve, reversing shaft 7, reversing handle 8 form; Be provided with two cavitys that built-in large small piston is connected with small piston in valve body, i.e. A chamber and B chamber, and this A chamber is connected by throttling duct with B chamber; With the reversing shaft 7 of reversing handle 8 being provided with three radial holes communicated with A chamber respectively, and three radial holes are communicated with by the oil duct on valve body 2 is corresponding respectively and controls gear I, gear II and neutral;
Described fine motion controlling component is made up of valve block 1, cone valve 12, hair 13, fine motion valve body 14, fine motion valve shaft 15 and inching valve handle 16; Fine motion valve body 14 to be connected on mutually on valve body 2 and to be connected with the B chamber in valve body 2 by a cone valve 12, fine motion valve body 14 is built with band spiral fluted fine motion valve shaft 15, fine motion valve shaft outer end is connected with inching valve handle, and the inner end of described fine motion valve shaft is connected with described cone valve 12 by hair.
Large piston 9 shown in Fig. 2 and the pressure spring be provided with between small piston 6 for forming setting pressure in A chamber; Oil-feed oil duct on valve body 2 is communicated with A chamber and B chamber respectively, and the fluid of oil-feed can be enable to arrive A chamber and B chamber simultaneously; Be placed in fine motion valve body 14 to be pressed on the cone valve 12 of valve body 2 connecting part and to be communicated with on the pressure regulation oil duct junction in B chamber, the fine motion valve shaft that described cone valve 12 and rear portion are settled is connected by hair, and changes hair to the impacting force of cone valve 12 by described fine motion valve shaft moving up and down in fine motion valve body 14.
Embodiment: fine motion selector valve of the present invention, is combined by commutation parts and fine motion controlling component two-part.
The composition such as individual event valve, reversing shaft 7, reversing handle 8 that described commutation parts are made up of valve body 2, three pressure springs 3,4,5, large piston 9, small piston 6, spring 10 and steel ball 11; Two cavitys be connected with large small piston, namely A chamber and B chamber, be connected by throttling pore.Reversing shaft 7 is provided with three radial holes, and communicates with A chamber respectively.From the fluid that three apertures flow out, by the oil duct on valve body 2, corresponding control gear I, gear II and neutral respectively.After fluid enters valve body 2, arrive A chamber and B chamber, under the effect of large piston 9 and small piston 6, three pressure springs 3,4,5 forced compression, form the pressure of setting in A chamber simultaneously.When reversing handle 8 rotates, drive reversing shaft 7 to rotate, working oil is flowed out by different holes, reaches the object of commutation.
Described fine motion controlling component is made up of valve block 1, cone valve 12, hair 13, fine motion valve body 14, fine motion valve shaft 15 and inching valve handle 16 etc.Fine motion valve shaft 15 is provided with spiral chute, under the drive of inching valve handle 16, fine motion valve shaft can move up and down in fine motion valve body 14, is changed the impacting force acted on cone valve 12 by hair 13, thus regulating the pressure in B chamber, A cavity pressure also changes thereupon.When reaching a certain force value, clutch friction plate starts to skid.
Operating oil pressure, in the continuous rotation process of inching valve handle, can be adjusted to minimum value from setting value by described fine motion selector valve continuously.
working procedure of the present invention is: when inching valve handle 16 is in off-position, cone valve 12 under spring force, being in closed condition, after fluid enters the A chamber of valve body 2, promoting small piston 6 toward moving left, open the spill port on valve body 2, and gush a part of fluid, simultaneously part fluid arrives B chamber by throttling pore, promotes large piston 9 and turns right and move to valve body 2 endoporus step place, by large and small two piston actions, oil liquid pressure arrives setting working pressure.Rotate reversing handle 8, drive reversing shaft 7 to rotate, pressure oil liquid is flowed out by holes different bottom valve body 2, arrives different gear clutchs, reaches the object of commutation.Now enter into the oil liquid pressure value of clutch oil cylinder for setting working pressure, master and slave of clutch friction plate engages non-slip completely, and transmission device is with constant output speed work.
When reversing handle is in any gear, rotary micromotion valve handle 16, fine motion valve shaft 15 is driven to move upward, the active force of hair 13 pairs of cone valves 12 progressively reduces, cone valve 12 will be in opening state, part fluid is by getting back to fuel tank after fine motion valve body 14, B cavity pressure reduces, pressure spring 3, 4, the decrement of 5 reduces, the pressure in A chamber also declines thereupon, when rotary micromotion valve handle 16 is to certain position, pressure is reduced to transition point, clutch friction plate starts to skid, be rotated further handle, pressure continues to reduce in more among a small circle, friction plate skid level continues to strengthen, therefore output speed reaches the object of stepless time adjustment.
The foregoing is only specific embodiments of the invention, but structure characteristic of the present invention is not limited thereto, any those skilled in the art is in the field of the invention, and the change done or modification are all encompassed among the scope of the claims of the present invention.
