Problems solved by technology

[0003] The temperature of the gearbox lubricating oil is generally not too high during normal driving. When the vehicle is overloaded or the four-wheel drive mode is set to drive on snow or off-road, and the vehicle is driving under the transitional slipping condition of the hydraulic torque converter, it may Cause transmission oil temperature to be too high, thus losing lubricating performance

specific Embodiment approach

[0032] Such as figure 1 The vehicle gearbox thermostat shown includes a valve body 102 provided with a cavity 105 and a thermodynamic element fitted in the cavity 105 . An elastic component is sheathed on the thermal power element, one end of the elastic component presses against the thermodynamic element, and the other end of the elastic component presses into contact with the hole wall of the second hole 107 through the communication hole 106 .

[0033] Such as figure 1 with figure 2 As shown, the valve body 102 also includes two through holes respectively communicating with the cavity 105 : a first hole 104 and a second hole 107 . Wherein, the first ends of the second hole 107 and the first hole 104 communicate with the inlet and outlet of the external fluid cooling device respectively; the second ends of the second hole 107 and the first hole 104 are the fluid inlet and the fluid outlet respectively.

[0034] In this embodiment, the second ends of the first hole 104 an...

Abstract

The invention relates to a temperature regulator for a gearbox of a vehicle, and the temperature regulator comprises a valve body provided with a cavity, and a thermal power element installed in the cavity, wherein the valve body further comprises two through holes, namely a first hole and a second hole which are respectively communicated with the cavity; first ends of the second hole and the first hole are communicated with the inlet and outlet of an external fluid cooling device respectively, and second ends of the second hole and the first hole are respectively provided with a fluid inlet and a fluid outlet; one end of the cavity is communicated with the second hole through an intercommunicating pore; and the thermal power element is fixedly mounted in the cavity, and an elastic component is sleeved on the periphery of the thermal power element, one end of the elastic component tightly props against the thermal power element, and the other of the elastic component is in compacting contact with the wall of the second hole through a communicating hole. By using the temperature regulator for the gearbox of the vehicle provided by the invention, the working temperature of lubricating oil can be controlled within an effective range, thereby maintaining the optimal state of the lubricating property of the lubricating oil.

Description

technical field [0001] The invention relates to the field of machinery, and more specifically, relates to a temperature regulator for a vehicle gearbox. Background technique [0002] During the driving process of the car, lubricating oil needs to be replenished in time to ensure the normal operation of the car. If the lubrication performance of the lubricating oil is not good enough, it will greatly reduce the service life of the car and even cause a car accident. The lubricating performance of lubricating oil is closely related to its own temperature. When the temperature of lubricating oil is too high or too low, the lubricating oil will lose its lubricating performance. [0003] The temperature of the gearbox lubricating oil is generally not too high during normal driving. When the vehicle is overloaded or the four-wheel drive mode is set to drive on snow or off-road, and the vehicle is driving under the transitional slipping condition of the hydraulic torque converter, ...
