Abstract
The utility model discloses a temperature regulating structure of an automobile automatic transmission and aims to solve the problem about temperature regulation of automatic transmission fluid (ATF). The utility model adopts the technical scheme that the temperature regulating structure of the automobile automatic transmission consists of an automatic transmission, a fluid cooler and a thermostat, wherein a first fluid inlet and a first fluid outlet, which are communicated with the automatic transmission, are formed on the left side of a valve body of the thermostat; and a second fluid inlet and a second fluid outlet, which are communicated with the fluid cooler, are formed on the right side of the valve body of the thermostat. The thermostat special for the automatic transmission is arranged between the automatic transmission and the fluid cooler, and the fluid inlets and the fluid outlets, which are respectively communicated with the automatic transmission and the fluid cooler, are formed on two sides of the thermostat. By adoption of the structure, large and small cycles of the ATF can be realized according to fluid temperature, so the temperature of the ATF keeps constant and is not changed along the change of working conditions and surrounding environment. The temperature regulating structure of the automobile automatic transmission has the advantages that the service life and fluid change period of the automatic transmission are prolonged, and fluid consumption is reduced.
Description
Technical field
The utility model relates to a kind of automobile component, and particularly the automatic gearbox temperature adjusting structure belongs to the automotive transmission technical field.
Background technique
See that from car load heat management angle motor car engine generally adopts the thermostat structure.The effect of motor thermostat is before the temperature of motor also reaches normal temperature, not to be in closed condition, and at this moment the cooling liquid of motor is carried out short circle in the motor through the water pump return engine, plays letting motor be rapidly heated; After surpassing normal temperature, can open, let cooling liquid carry out major cycle, thereby quick heat radiating help engine operation through whole radiator of water tank loop.The market share of automatic transmission car is improving constantly in recent years, and the Consumer requires improving constantly to automatic transmission vehicle energy saving property and critical component working life, but on the automatic transmission thermostat is not installed generally at present.The automatic transmission vehicle all is to rely on hydraulic pressure ATF oil to carry out power transmission mostly, and the temperature of hydraulic oil might might rise in a few minutes more than 100 ℃, should in time cool off ATF hydraulic oil, and ATF oil is remained in the normal range of operation.Therefore from the basic demand of automatic transmission, should help automatic transmission work like this with oily temperature control within limits equally, improve automatic transmission life-span and drain period.
The model utility content
The utility model is used to overcome the deficiency of existing technology, and a kind of automatic gearbox temperature adjusting structure that improves speed changer life-span and drain period is provided.
The alleged problem of the utility model realizes with following technical proposals:
A kind of automatic gearbox temperature adjusting structure; Specialization is: it is made up of automatic transmission, oil cooler and thermostat; The valve body left side of said thermostat is provided with first filler opening, first oil outlet that is communicated with automatic transmission, and the right side is provided with second filler opening, second oil outlet that is communicated with oil cooler.
Above-mentioned automatic gearbox temperature adjusting structure, said thermostat comprises valve body, spool, push rod and return spring, the valve body middle part is provided with spool chamber; Spool chamber is communicated with first filler opening, first oil outlet, second filler opening, second oil outlet; Side lower part at first filler opening of valve body is provided with the short circle path that is communicated with first filler opening and spool chamber, and said spool is positioned at the spool chamber of valve body, and said return spring is positioned at the spool bottom; Touch with spool; Said push rod bottom is positioned at spool, and the push rod upper end is spacing by jump ring, fills paraffin in the said spool.
Above-mentioned automatic gearbox temperature adjusting structure is provided with seal ring between said spool and the push rod.
The utility model is not provided with thermostat to existing car automatic transmission, is unfavorable for that the problem of ATF oil temperature adjusting is improved, and has designed a kind of automatic gearbox temperature adjusting structure.Said structure is installed in the special-purpose thermostat of a kind of automatic transmission between automatic transmission and the oil cooler; The thermostat both sides are provided with and are communicated with automatic transmission and oil cooler respectively into and out of hydraulic fluid port; This structure can realize the big short circle of automatic transmission fluid (ATF) according to the oil temperature; Thereby make ATF keep constant temperature, the variation with operating mode and surrounding environment does not change.The utility model helps improving automatic transmission life-span and drain period, reduces oil consumption.
Description of drawings
Fig. 1 is the utility model schematic representation;
Fig. 2 is the thermostat structural representation.
Each label is among the figure: 1. speed changer; 2. thermostat; 2-1. valve body; 2-1-1. first filler opening; 2-1-2. first oil outlet; 2-1-3. second oil outlet; 2-1-4. second filler openings; 2-1-5. short circle path; 2-2. push rod; 2-3. jump ring; 2-4. seal ring; 2-5. spool; 2-6. paraffin; 2-7. return spring; 3. oil cooler.
Embodiment
Referring to Fig. 1, the utility model is made up of automatic transmission 1, oil cooler 3 and thermostat 2.Thermostat is provided with valve body 2-1, is provided with the first filler opening 2-1-1, the first oil outlet 2-1-2 that is communicated with automatic transmission in valve body 2-1 left side, and the valve body right side is provided with the second filler opening 2-1-4, the second oil outlet 2-1-3 that is communicated with oil cooler.
Referring to Fig. 1, Fig. 2, said thermostat 2 comprises valve body 2-1, spool 2-5, push rod 2-2 and return spring 2-7.The valve body middle part is provided with spool chamber; Spool chamber is communicated with first filler opening, first oil outlet, second filler opening, second oil outlet respectively; Side lower part at valve body first filler opening is provided with the short circle path 2-1-5 that communicates with first oil outlet, and this short circle path is communicated with first filler opening and spool chamber.Spool 2-5 is installed in the spool chamber of valve body, and return spring 2-7 is positioned at the spool bottom, and return spring top and spool touch.Push rod 2-2 bottom is positioned at spool, but both slide relative are filled paraffin 2-6 in the spool, reveals for preventing liquid paraffin, is provided with seal ring 2-4 between spool 2-5 and the push rod 2-2.The push rod upper end is spacing by jump ring 2-3.
Referring to Fig. 1, Fig. 2, the utility model working procedure is following: when engine idle or ambient temperature were low, the transmission oil temperature was lower, did not need heat radiation, carried out short circle.At this moment, the paraffin 2-6 among the spool 2-5 is in solid-state.Spool is positioned at the topmost part shown in Figure 2, and transmission oil gets into thermostat by the first filler opening 2-1-1 of thermostat, is flowed back in the speed changer 1 by the first oil outlet 2-1-2 through short circle path 2-1-5, spool chamber, dispels the heat without oil cooler.When low speed driving in the vehicle or ambient temperature are higher, the transmission oil temperature rise, at this moment the paraffin 2-6 among the spool 2-5 is molten into liquid state; Because paraffin has the characteristic of liquid volumetric expansion; Paraffin promotes push rod, because push rod is spacing through jump ring 2-3, moves down thereby oppositely promote spool compression retracteding position spring 2-7; The major cycle path is opened; Transmission oil is got in the thermostat by the first filler opening 2-1-1 of thermostat 2, gets into oil cooler 3 coolings through the second oil outlet 2-1-3, and the oil of process oil cooler heat radiation flows back in the speed changer through the second filler opening 2-1-4 and the first oil outlet 2-1-2 again.
