The present invention has the fluid torque converter of hydrodynamic temperature automatic adjustment device, comprises fluid torque converter and radiator, also comprises heat-operated valve; Fluid torque converter is provided with hydrodynamic outer pipe and hydrodynamic inlet tube, hydrodynamic inlet tube is connected with radiator with hydrodynamic outer pipe; Heat-operated valve is contained in hydrodynamic inlet tube and the hydrodynamic outlet pipe end place of close fluid torque converter; Described heat-operated valve comprises valve body, spool, spring, piston pole socket and piston rod; Spool, spring and piston pole socket are contained in valve body, and one end of spring contacts with the interior step of valve body, and the other end contacts with the outer step of spool; Spool mesopore is rod end chamber, and described rod end chamber is blind hole and at its hypomere, temperature-sensitive rubber is housed; The lower end surface of temperature-sensitive rubber and the bottom connection in valve core piston bar chamber touch; Piston rod and piston pole socket connect as one, and piston rod hypomere loads in the rod end chamber of spool, and can slide wherein, piston-rod lower end contacts with the upper-end surface of temperature-sensitive rubber; Valve body has valve body import and valve outlet, valve body import is connected with the hydrodynamic outer pipe of fluid torque converter, and valve outlet is connected with the hydrodynamic inlet tube of fluid torque converter.
The present invention has the beneficial effect of the fluid torque converter of hydrodynamic temperature automatic adjustment device to be the import and export pipe end that heat-operated valve is contained near fluid torque converter, and the temperature of hydrodynamic in direct feeling fluid torque converter, ensures the normal work of fluid torque converter.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present invention.In figure, 1 is fluid torque converter, and 2 is heat-operated valve, and 3 is radiator, and 4 is hydrodynamic outer pipe, 5 is hydrodynamic inlet tube, and 6 is valve body, and 7 is spool, and 8 is spring, and 9 is piston pole socket, 10 is piston rod, and 11 is rod end chamber, and 12 is temperature-sensitive rubber, and 13 is valve body import, and 14 is valve outlet.
Embodiment
As shown in Figure 1, the present invention has the fluid torque converter of hydrodynamic temperature automatic adjustment device, comprises fluid torque converter 1 and radiator 3, it is characterized in that, also comprise heat-operated valve 2; Fluid torque converter 1 is provided with hydrodynamic outer pipe 4 and hydrodynamic inlet tube 5, hydrodynamic inlet tube 5 is connected with radiator 3 with hydrodynamic outer pipe 4; Heat-operated valve 2 is contained in hydrodynamic inlet tube 5 and the hydrodynamic outer pipe 4 end place of close fluid torque converter 1; Described heat-operated valve 2 comprises valve body 6, spool 7, spring 8, piston pole socket 9 and piston rod 10; Spool 7, spring 8 and piston pole socket 9 are contained in valve body 6, and one end of spring 8 contacts with the interior step of valve body 6, and the other end contacts with the outer step of spool 7; Spool 7 mesopore is rod end chamber 11, and described rod end chamber 11 is blind hole and at its hypomere, temperature-sensitive rubber 12 is housed; The lower end surface of temperature-sensitive rubber 12 and the bottom connection of spool 7 rod end chamber 11 touch; Piston rod 10 and piston pole socket 9 connect as one, and piston rod 10 hypomere loads in the rod end chamber 11 of spool 7, and can slide wherein, piston rod 10 lower end contacts with the upper-end surface of temperature-sensitive rubber 12; Valve body 6 has valve body import 13 and valve outlet 14, valve body import 13 is connected with the hydrodynamic outer pipe 4 of fluid torque converter 1, and valve outlet 14 is connected with the hydrodynamic inlet tube 5 of fluid torque converter 1.
When hydrodynamic temperature is low temperature, temperature-sensitive rubber 12 in spool 7 rod end chamber 11 experiences the hydrodynamic temperature of low temperature, small volume, because one end of spring 8 contacts with step in valve body 6, the other end contacts with the outer step of spool 7, spool 7 under spring 8 resilient force on move, valve body import 13 is communicated with valve outlet 14, the hydrodynamic of fluid torque converter 1 directly flows back to fluid torque converter 1 by hydrodynamic outer pipe 4 through the valve body import 13 of heat-operated valve, valve outlet 14 and hydrodynamic inlet tube 5, and without radiator 3, hydrodynamic keeps low temperature.When hydrodynamic temperature is high temperature, temperature-sensitive rubber 12 in spool 7 rod end chamber 11 experiences the hydrodynamic temperature of high temperature, volume increases, because the lower end surface of temperature-sensitive rubber 12 and the bottom connection of spool 7 rod end chamber 11 touch, piston rod 10 lower end contacts with the upper-end surface of temperature-sensitive rubber 12, the volume of temperature-sensitive rubber 12 increases elastic force promotion spool 7 being overcome spring 8 and moves to bottom, spool 7 is by the pathway closure between valve body import 13 and valve outlet 14, the hydrodynamic of fluid torque converter is not refluxed by heat-operated valve, now hydrodynamic is by hydrodynamic outer pipe 4 inflow radiator 3, after radiator 3 is lowered the temperature, fluid torque converter 1 is flowed back to by hydrodynamic inlet tube 6, hydrodynamic is made to keep low temperature, thus ensure that fluid torque converter normally works.
Obviously, the present invention has the beneficial effect of the fluid torque converter of hydrodynamic temperature automatic adjustment device to be the import and export pipe end that heat-operated valve is contained near fluid torque converter, and the temperature of hydrodynamic in direct feeling fluid torque converter, ensures the normal work of fluid torque converter.
