A thermo valve 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 2.

According to the utility model discloses temperature-sensing valve 100 can include: valve body 1, inflation core 2, guide push rod 3 and buffer 4.

As shown in fig. 1 and 2, the thermo-valve 100 is a mechanism for adjusting the temperature of the transmission, in which one end of the thermo-valve 100 is connected to the transmission and the other end is connected to the oil cooler, and removes excess heat of the transmission by the circulation flow of cooling oil.

Wherein, the expansion core 2 is the important structure of temperature-sensing valve 100, it sets up in valve body 1, the expansion core 2 has the characteristic of meeting thermal expansion, and in a certain extent, along with the rising of temperature, the volume of expansion core 2 can expand the big more, and utilize this expansion characteristic, make expansion core 2 can change the intercommunication condition of the different passageways of the internal cavity of valve body 1 when expanding, thereby make expansion core 2 under the expansion state and normal condition with the intercommunication condition of the internal passageway of valve body 1 different, and then realized two kinds of modes of low temperature closed mode and high temperature open mode of temperature-sensing valve 100.

When the transmission is in the normal temperature range, the expansion core 2 does not react due to insufficient temperature, and the thermostatic valve 100 is in the low-temperature closing mode.

When the gearbox is at a temperature higher than the normal temperature, the expansion core body 2 is heated to expand, so that the communication condition of the cavity in the valve body 1 is changed, oil with higher temperature in the gearbox can flow into the oil cooler through the valve body 1 to be cooled and then flows back into the gearbox, the temperature of the gearbox is reduced, and the temperature control valve 100 is in a high-temperature opening mode.

Further, a guide push rod 3 is further arranged in the valve body 1, and the guide push rod 3 is matched with the expansion core body 2 in a guide mode. In other words, the guiding rod 3 provides the expansion core 2 with the guidance in the expansion direction, so that the expansion core 2 can expand in the preset direction to smoothly change the communication condition of the passage in the valve body 1.

However, the guide push rod 3 in the conventional thermostatic valve 100 is directly matched and fixed with the valve body 1, and relative movement cannot be performed between the guide push rod 3 and the valve body 1, so that the expansion core body 2 is easily extruded with the guide push rod 3 after over expansion, and because the guide push rod 3 is of a rigid structure and the expansion core body 2 is of a flexible structure, the guide push rod 3 can damage the expansion core body 2, and the expansion core body 2 is damaged.

In order to solve the problem, the embodiment of the present invention provides a buffer member 4 in the valve body 1, and the other end of the guiding pushing rod 3, which is far away from the expansion core 2, is elastically stopped by the buffer member 4. In other words, one end of the guide rod 3 is guided and engaged with the expansion core 2, and the other end is elastically stopped by the buffer 4.

From this, when inflation core 2 overexpansion and extrusion direction push rod 3, direction push rod 3 can continue to extrude bolster 4 and alleviate the extrusion force to reduce the extrusion effort between direction push rod 3 and the inflation core 2, and then the effectual condition of taking place direction push rod 3 and smashing inflation core 2 of taking place.

According to the utility model discloses temperature-sensing valve 100, this temperature-sensing valve 100 sets up the bolster 4 that ends with 3 looks elasticity of guide push rod at the other end of the expansion core of keeping away from of guide push rod 3 to reduce the extrusion effort between guide push rod 3 and the expansion core 2, and then effectual protection expansion core 2 avoids the extrusion harm of guide push rod 3.

With reference to the embodiment shown in fig. 1 and 2, a buffer limiting structure 5 is provided in the valve body 1, the buffer 4 is disposed in the buffer limiting structure 5, and the other end of the guide push rod 3 is limited in the buffer limiting structure 5. The buffer limiting structure 5 is arranged to effectively limit the buffer 4 and the guide push rod 3, namely, the buffer 4 is limited in the buffer limiting structure 5, so that the normal operation of the temperature control valve 100 is prevented from being influenced by the random movement of the buffer in the valve body 1, and the guide push rod 3 can not move towards the expansion core body 2 continuously under the thrust action of the buffer 4, so that the normal operation of the temperature control valve 100 is prevented from being influenced.

Further, the guide pusher 3 includes: the push rod body 31 and the limit stop seat 32, wherein the limit stop seat 32 is arranged at the other end of the guide push rod 3, a through hole 51 is formed in one side wall of the buffer limiting structure 5 close to the expansion core body 2, the push rod body 31 is suitable for penetrating through the through hole 51, and the limit stop seat 32 is limited in the buffer limiting structure 5. From this, can avoid guide push rod 3 to break away from bolster limit structure 5 completely to guarantee guide push rod 3's stability of setting.

Referring to fig. 1 and 2, the buffer member 4 is disposed between a side wall of the buffer member limiting structure 5 away from the expansion core 2 and the limiting stop seat 32 to ensure that the buffer member 4 can buffer and offset the extrusion force from the expansion of the expansion core 2, and also ensure that the buffer member 4 can assist the force to restore the guide push rod 3 and the expansion core 2 to the initial positions after the expansion core 2 contracts.

In connection with the embodiment shown in fig. 1 and 2, the limit stop seat 32 includes: the positioning column 321 and the stopping flange 322 extending outwards from one end of the positioning column 321 close to the expansion core body 2 are inserted into the buffer member 4 to play a role in positioning and guiding, and the stopping flange 322 is stopped against the buffer member 4, so that the buffer member 4 can be extruded and buffered with the guide push rod 3 more stably.

Specifically, because spacing backstop seat 32 can take place mutual extrusion and remove with bolster 4, when spacing backstop seat 32's extrusion force was greater than bolster 4's elastic restoring force, spacing backstop seat 32 can promote bolster 4 and move towards the direction of keeping away from inflation core 2, at this moment, because reference column 321 stretches into in bolster 4, consequently, reference column 321 can play fine guide effect, guarantees bolster 4 and compresses along fixed direction to avoid the phenomenon that the compression card went on or the phenomenon that guide push rod 3 extrudees bolster 4 and damages appears.

Preferably, the through hole 51 of the buffer limiting structure 5 is suitable for being closely attached to the push rod body 31, and the through hole 51 is suitable for being opposite to the buffer 4, so that when the buffer 4 pushes the guide push rod 3 to move towards the expansion core 2, the guide push rod can move along a predetermined straight direction through the guide fit between the push rod body 31 and the through hole 51 and the guide fit between the positioning column 321 and the buffer 4, so as to ensure that the expansion core 2 can be restored to an initial position, and further avoid the phenomenon of jamming in the process.

As shown in fig. 1 and 2, the valve body 1 has a valve body cavity 11, and the valve body cavity 11 includes: the first section 111 and the second section 112 and the third section 113 which are connected with two ends of the first section 111, the first section 111 is communicated with a transmission oil outlet channel 12, oil in the transmission can enter the first section 111 through the transmission oil outlet channel 12, the second section 112 is communicated with an oil cooler oil inlet channel 13, oil in the second section 112 can enter an oil cooler through the oil cooler oil inlet channel 13, the third section 113 is communicated with an oil cooler oil outlet channel 14 and a transmission oil return channel 15, oil in the third section 113 can enter the transmission through the transmission oil return channel 15, the oil in the oil cooler can flow back to the transmission through the oil cooler oil outlet channel 14 and the transmission oil return channel 15, and the second section 112 is selectively communicated with the first section 111 and the third section 113 to complete switching of the temperature control valve 100 between a low-temperature closing mode and a high-temperature opening mode.

Specifically, when the temperature of the oil in the gearbox is low, the thermostatic valve 100 is in a low-temperature closing mode, the expansion core body 2 is blocked between the first section 111 and the second section 112, so that the first section 111 and the second section 112 are not communicated, the second section 112 and the third section 113 are communicated, and at the moment, the oil in the gearbox does not need to be cooled, so that the oil does not need to flow through an oil cooler, the oil in the gearbox enters the first section 111 from the gearbox oil outlet channel 12, flows into the third section 113, and finally flows back into the gearbox from the gearbox oil return channel 15, so that the internal pressure of the gearbox is stable.

When the temperature of the oil in the gearbox is high, the temperature control valve 100 is changed from a low-temperature closing mode to a high-temperature opening mode, the expansion core body 2 is expanded by high temperature to be isolated between the first section 111 and the third section 113, so that the first section 111 and the third section 113 are not communicated, the second section 112 and the third section 113 are communicated by opening, at the moment, the oil in the gearbox enters the first section 111 from the oil outlet channel 12 of the gearbox and flows into the second section 112, then flows into the oil cooler from the oil cooler oil inlet channel 13 for cooling, and the cooled oil with low temperature flows back into the gearbox through the oil cooler oil outlet channel 14 and the gearbox oil return channel 15 in sequence to reduce the temperature of the gearbox.

With reference to the embodiment shown in fig. 1 and 2, a choke baffle 6 is disposed between the first segment 111 and the second segment 112, and the choke baffle 6 has a slow flow communication hole 61 for communicating the second segment 112 and the first segment 111. The provision of the buffer communication hole 61 enables oil entering the first section 111 from the transmission to flow slowly into the second section 112 and then into the oil cooler when the thermostatic valve 100 is in the low temperature closed mode.

Specifically, when the thermostatic valve 100 is in the low-temperature closed mode, the expansion core body 2 cooperates with the flow blocking baffle 6 to block the first section 111 and the second section 112 from being communicated with each other, at this time, the oil in the first section 111 slowly flows into the second section 112 from the flow blocking communication hole 61 and then flows into the oil cooler, and finally slowly flows back into the transmission, but in the process, the oil cooler is slowly filled with the oil, so that the air in the oil cooler is completely discharged, the air is prevented from being mixed in the oil to influence the normal cooling of the oil and the normal operation of the transmission in the transmission.

And, the fluid when being at low temperature can have the effect of preheating to the oil cooler from the slow inflow oil cooler in the intercommunicating pore 61 that flows slowly to a certain extent, when avoiding temperature-sensing valve 100 to change from low temperature closed mode to high temperature open mode suddenly, the fluid of high temperature gets into rapidly in the oil cooler and causes cold and hot impact and make the oil cooler damage to the lower oil cooler of temperature, and then can increase the life of oil cooler.

Furthermore, in the structure that does not have slow flow intercommunicating pore 61 in traditional temperature-sensing valve 100, when the gearbox had the heat dissipation demand and temperature-sensing valve 100 changed into the high temperature mode of opening, the oil cooler need can cool down the work with inside air exhaust rear to the greatest extent, leads to the heat dissipation demand that can not respond to the gearbox in time. And the embodiment of the utility model provides an utilize slow flow intercommunicating pore 61's slow switching-on effect, just carry oil feed cold ware in with fluid when temperature-sensing valve 100 is in low temperature closed mode to discharge the air in the oil cold ware, when temperature-sensing valve 100 changes the high temperature from low temperature closed mode into and opens the mode, the reaction of making that the oil cold ware can be quick, cool down fluid, with better protection gearbox.

Referring to fig. 1 and 2, the baffle 6 further has flow holes 62, the expansion core 2 may block or open the flow holes 62 to block or connect the first section 111 and the second section 112, and the slow flow communication hole 61 has a diameter much smaller than that of the flow holes 62. The diameter of the slow flow communication hole 61 is set to be small so as to prevent the flow rate of the oil liquid flowing into the oil cooler through the slow flow communication hole 61 from being too fast to exhaust the air in the oil cooler.

In a preferred embodiment, the diameter of the communication hole 61 is one tenth of the diameter of the liquid flow hole 62. From this, can avoid flowing through slow flowing the fluid velocity of flow of intercommunicating pore 61 too fast and not discharging the air in the clean oil cooler, also can avoid the condition that the gearbox that leads to because the fluid velocity of flow is too slow only produces oil for a long time and does not return the oil, and then avoids the emergence of gearbox starving phenomenon and damages the gearbox.
