Abstract
The utility model relates to the hydraulic oil control of a variable speed case. The buffering power accumulator of the variable speed case is arranged on the oil inlet line (5) of a clutch in parallel, and the buffering power accumulator mainly comprises a casing body (6), a power accumulator plunger (3), and a seal ring (4). The power accumulator plunger (3) is positioned in the casing body (6) and matched with the clearance of the casing body (6), one end of a spring is positioned in a mounting slot at the tail end of the power accumulator plunger, and a spring room is communicated with the interior of an oil drainage opening or a speed changer. The utility model can absorb energy when the pressure of the oil line is strong, and play the functions of buffering and accumulation of energy, when the pressure of the oil line is low, the utility model releases partial energies and compensates to the pressure, the circumstance of the abrupt change of the pressure of the hydraulic oil can be eliminated, thereby ensuring that the wet type clutch operates within the specific pressure, and ensuring the smoothness of the combination and disconnection of the clutch. The utility model has the advantages that the structural design is simple and reasonable, and the operational reliability is high.
Description
Technical field:
The utility model relates to the hydraulic oil control of stepless speed variator, mainly proposes a kind of buffering accumulated energy device of stepless speed variator.
Background technique:
Jointly control in the stepless speed variator at the electric liquid that the applicant proposed, the interlock of the forward gear clutch in the mission case and engine output shaft is directly accepted engine output power and is delivered on the initiative taper dish axle of variable part.This clutch adopts the wet friction clutch structure of hydraulic control, clutch oil cylinder passes through control valve supply pressure oil by oil feed line, according to design control oil pressure, clutch pressure is pressurizeed (or decompression) with microprocessor gradually by the curve of setting, make the smooth-going combination of clutch and separate.And there is the fluctuation of load at work in clutch, has influence on the variation of pressure oil, and this just requires to have a kind of device that pressure oil is controlled and regulated, and promptly cushions when oil pressure is big, hour it is compensated at oil pressure.
Summary of the invention:
The purpose of this utility model promptly is the buffering accumulated energy device that proposes a kind of stepless speed variator, is used to control and regulate the pressure of pressure oil.
The utility model is finished the technological scheme that its invention task proposed: the buffering accumulated energy device is arranged in parallel in the in-line of clutch, it mainly is made of housing, accumulator plunger, spring and seal ring, the accumulator plunger is positioned at housing and cooperates with body clearance, spring one end is positioned at the mounting groove of accumulator plunger tail end, and spring housing is by the drain tap on the housing and fuel tank or speed changer internal communication.
The utility model is arranged in parallel in the in-line of clutch, and when loine pressure increased, pressure oil promoted the accumulator plunger and moves along housing, pressure spring, and the absorption portion energy plays buffering and energy storage effect; When loine pressure hour, pressure spring return, by accumulator plunger drawback movement, the release portion energy compensates pressure.Absorption and the process that releases energy are exactly adjustment and the stabilization process to hydraulic system pressure, and the rapid change situation that can eliminate hydraulic fluid pressure takes place, thereby the assurance wet clutch is worked the combination of assurance clutch, the smoothness that separates in the specific pressure of regulation.
The utility model structural design advantages of simple, functional reliability is higher.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Among the figure, 1-big spring, 2-little spring, 3-accumulator plunger, 4-seal ring, 5-clutch in-line, 6-housing.
Embodiment:
The accompanying drawing that provides is in conjunction with the embodiments further specified its structure:
As shown in Figure 1, the buffering accumulated energy device is arranged in parallel in the in-line (5) at clutch, it mainly is made of housing 6, accumulator plunger 3, spring and seal ring 4, accumulator plunger 3 be positioned at housing 6 and with housing 6 Spielpassung, move along housing 6 under pressure.Accumulator plunger 3 front ends are provided with seal ring 4, prevent leakage of oil in order to play seal action.Be sleeved on together inside and outside big spring 1, the little spring 2, their end is installed in the mounting groove of accumulator plunger 3 tail ends, and spring housing is by the drain tap on the housing and fuel tank or speed changer internal communication; Sealing 4 can be adopted polytetrafluoroethylmaterial material; The accumulator spring is combined by big spring 1 and little spring 2 inside and outside suits, and is installed in the mounting groove of accumulator plunger, can effectively increase spring rate like this under the less prerequisite of physical dimension, thereby improve the buffer function of accumulator.
Claims (2)
1. the buffering accumulated energy device of a stepless speed variator, it is characterized in that: the buffering accumulated energy device is arranged in parallel in the in-line of clutch, it mainly is made of housing (6), accumulator plunger (3), spring and seal ring (4), accumulator plunger (3) be positioned at housing (6) and with housing (6) Spielpassung, spring one end is positioned at the mounting groove of accumulator plunger tail end, and spring housing is by the drain tap on the housing and fuel tank or speed changer internal communication.
