Abstract
The utility model belongs to a hydraulic pressure balance control art for a stepless derailleur. The stepless derailleur can be used as a dynamical pressure balance element for a movable cone oil cylinder; the technical scheme for the utility model is that: an assistant oil cylinder (1) is arranged on the outer side of the movable cone oil cylinder (6); the appearance of the assistant oil cylinder (1) is basically matched with the oil cylinder (6); and moreover the oil cylinder (6) is enveloped by the assistant oil cylinder from the outer side; a big end of the assistant oil cylinder (1) is fixed on a movable cone (3) through a hole-used clip spring (2); and a small end is freely covered on a fixed cone axis (7). When the assistant oil cylinder used as the balance element provided in the utility model is running, the hydraulic oil in the cavity room of the assistant oil cylinder will lead to a dynamical pressure because of a centrifuge force; the dynamical pressure is balanced to the dynamical pressure brought by the hydraulic pressure oil in the movable cone oil cylinder because of the centrifuge force. So the design structure can eliminate the influence to the control precision for the hydraulic pressure because of the dynamical pressure brought by the centrifuge force.
Description
Technical field:
The utility model belongs to stepless speed variator hydraulic oil Balance Control technology, but mainly proposes a kind of dynamic pressure balancing mechanism of stepless speed variator mantle dish oil cylinder.
Background technique:
In stepless speed variator, but, cause the change of the transmission radius of awl dish and driving belt, thereby change the velocity ratio of speed changer, realize the purpose of speed governing by the gap between mantle dish and fixed cone dish is adjusted.And but the adjustment in awl dish gap is to realize by the relative position of adjusting the mantle dish, but the change of mantle dish relative position by but the in-oil cylinder oil pressure of mantle dish is accurately controlled realization, but therefore the control accuracy of mantle dish oil cylinder oil pressure is required than higher.But, but the mantle dish is when running up, in-oil cylinder hydraulic oil can produce different centrifugal force along with the difference of rotating speed, because the dynamic pressure that centrifugal action produces will produce huge adverse effect to the control of clamping force and speed ratio, even speed Control can not be realized.But the dynamic pressure influence of the stepless change mantle dish oil cylinder in using at present automatically controlled compensation way or other machinery types of adopting solve more.
Summary of the invention:
But the purpose of this utility model is the dynamic pressure balancing mechanism that proposes a kind of stepless speed variator mantle dish oil cylinder, but makes it carry out balance to the dynamic pressure of mantle dish oil cylinder, thereby eliminates the influence of centrifugal force to the hydraulic control precision.
The utility model is finished the technological scheme that its invention task proposed: but at arranged outside one auxiliary cylinder of mantle dish oil cylinder, but the profile of auxiliary cylinder and mantle dish oil cylinder are kissed substantially and are joined and it is surrounded from the outside; But the inwall of auxiliary cylinder constitutes the auxiliary cylinder chamber with mantle dish oil cylinder outer wall; But the big end of auxiliary cylinder is fixed on the mantle dish with jump ring by the hole, and the small end freedom suit is on fixed cone dish axle.
But the auxiliary cylinder of balanced controls that the utility model the proposes hydraulic oil in its chamber in the running can produce the centrifugal force that hydraulic pressure produces in centrifugal force and the mantle dish oil cylinder equally and balances each other, and eliminates the influence of centrifugal force to the hydraulic control precision thus.
The utility model is simple in structure, convenient processing and manufacture.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Among the figure, 1-auxiliary cylinder, 2-hole jump ring, but 3-mantle dish, 4-driving belt, 5-fixed cone dish, but 6-mantle dish oil cylinder, 7-fixed cone dish axle, 8-oil inlet hole.
Embodiment:
The accompanying drawing that provides is in conjunction with the embodiments further specified its structure:
As shown in Figure 1, in stepless speed variator, but adjust, cause the change of the transmission radius of awl dish and driving belt 4, thereby change the velocity ratio of speed changer, the purpose of realization speed governing by gap to 5 on mantle dish 3 and fixed cone dish.But the change of mantle dish 3 relative positions is by but the oil pressure in the mantle dish oil cylinder 6 is accurately controlled realization.But arranged outside one auxiliary cylinder 1 at mantle dish oil cylinder 6, the profile of auxiliary cylinder 1 and oil cylinder 6 basic kisses are joined and oil cylinder 6 are surrounded from the outside, the outer wall of the inwall of auxiliary cylinder 1 and oil cylinder 6 constitutes the auxiliary cylinder chamber, but the big end of auxiliary cylinder 1 is fixed on the mantle dish 3 with jump ring 2 by the hole, and the small end freedom suit is on fixed cone dish axle 7.Auxiliary cylinder 1 is by oil inlet hole 8 oil-feeds on the fixed cone dish axle 7.
