Abstract
The utility model belongs to the technical field of mechanical equipment, which relates to a thermostat, in particular to an engine thermostat. The technical problems of short service life, difficulty in cooling of a retarder, easiness in backflow of a cooling liquid and the like are solved by the engine thermostat. The engine thermostat comprises a shell, wherein two sets of thermostat components are symmetrically arranged in the shell, and a water inlet pipe, a water outlet pipe and a by-pass pipe are connected to the shell. The engine thermostat has the advantages of reasonable design, simple structure, stable performance and long service life, the problem of desynchrony of the retarder and the maximum heat load of an engine can be solved, reliable cooling of the retarder can be guaranteed, and the cooling liquid in the retarder is prevented from backflow.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to thermostat, especially relates to a kind of external thermostat for motor car engine.
Background technique
Improvement along with socioeconomic development and people's living standard; automobile obtains using more and more widely as the traffic tool commonly used; the advantages such as the automobile of joining automatic transmission case or hydrodynamic retarder,, gearshift light with its operation are steadily, ride comfort, overload protection performance be good are subject to liking of users gradually.Present widely used automatic transmission case, perhaps mechanical gear box band retarder, their bending moments or the heat that produces when slow generally all are to pass to gearbox cooler by hydraulic oil, pass to the cooling system of motor by gearbox cooler by the exchange heat of hydraulic oil and cooling liquid again, finally by the cooling system of motor heat is taken away.In order to allow the cooling unit of these additional devices and heat and motor and heat be combined well coupling, at present the general method that adopts is that gearbox cooler is installed on the water tank egress line between water tank and the pump entrance, and eliminating to the pipeline of gearbox cooler entrance by the thermostat bypass valve does not have the deficiency that circulates when thermoregulator cuts out.This circulation style is when startup and long descending operating mode, be easy to cause that speed changer is overheated, cold oil boiling and motor is in the state of short circle is so that the poor-performing of thermostat, working life is short, exists simultaneously retarder to be difficult to cooling, the defectives such as backflow easily occur cooling liquid.
The problem that exists in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of automobile thermostat [application number: CN200520070325.3], comprise end cap, support, liftout mechanism and be fixed on the liftout mechanism valve gap with its interlock, base, described liftout mechanism comprises tubbiness spring storage chamber, sealing cover and central ejector rod, the sealing cover center is provided with the through hole that is slidingly fitted with the central ejector rod diameter, central ejector rod one end passes from through hole, spring is store indoor chamber the helical spring of being made by memory alloy is housed, described helical spring lower end is against intracavity bottom, and top is against on another termination of central ejector rod.
Such scheme has improved prior art to a certain extent, and the helical spring that adopts memory alloy to make has improved the performance and used life of thermostat.Yet this scheme can not solve still that retarder is difficult to cooling, the technical problems such as backflow easily occur cooling liquid.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, stable performance, and long service life can guarantee the reliable cooling of retarder, avoids the motor thermostat that cooling liquid refluxes in the retarder.
For achieving the above object, the utility model has adopted following technical proposal: this motor thermostat, comprise housing, and in housing, be provided with the thermostat assembly, be connected with inlet pipeline, rising pipe and bypass line at housing, described thermostat assembly is two groups and is symmetricly set in the housing.
As a kind of technological scheme of comparatively optimizing, in above-mentioned motor thermostat, described thermostat assembly adopts wax formula structure.
In above-mentioned motor thermostat, described housing comprises loam cake and the lower casing of mutual fastening, and described rising pipe is connected to and covers, and described inlet pipeline and bypass line are connected on the lower casing.
Further, in above-mentioned motor thermostat, be provided with seal ring between described thermostat assembly and the housing.
Further, in above-mentioned motor thermostat, described wax formula structure comprises center-pole, is provided with paraffin in the outside of center-pole, is provided with spring in the outside of paraffin.
Compared with prior art, the advantage of this motor thermostat is: reasonable in design, simple in structure, stable performance, long service life can solve retarder and the nonsynchronous problem of motor maximum heating load, can guarantee the reliable cooling of retarder, avoid cooling liquid backflow in the retarder.
