Abstract
The utility model relates to a cooling system of a speed changing box. The cooling system comprises a water tank, an engine oil radiator, a water pump arranged on an engine and a water jacket arranged above the engine oil radiator. A large circulation pipe is communicated with the top of the water tank, and a water pump water inlet pipe is communicated with the bottom of the water tank. The other end of the water pump water inlet pipe is communicated with the water pump. The other end of the water pump is communicated with a small circulation pipe. A fan is arranged on one side of the small circulation pipe. A thermostat is communicated with the other end of the small circulation pipe. The engine oil radiator, the water jacket and the large circulation pipe are respectively communicated with the thermostat through pipelines. By the adoption of the design, the cooling system of the speed changing box can quickly cool the speed changing box, and is reasonable in designed structure.
Description
Technical field
The utility model relates to the field of cooling unit, especially a kind of cooling system for speed changing box.
Background technique
Because the component such as piston, cylinder liner, cylinder head, valve absorb a large amount of heat because contacting with high-temperature fuel gas, cause that temperature sharply raises, part strength sharply descends, part deformation is accelerated and wearing and tearing too early, and machine oil is rotten, can not normally lubricate.While part expanded by heating, destroy the normal matching gap of part, cause and pull, stuck, high temperature affects intake temperature simultaneously to be increased, density descends, entering the firing chamber gaseous mass reduces, cause that gearbox power descends, therefore gearbox work must obtain good cooling, normal cooling liquid outlet temperature at 80～100 ℃ better, this antifreeze liquid kind with the pressure cover cracking pressure of swelling water tank and use is relevant, sometimes can reach 110 ℃, otherwise, undercooling, to gearbox, work also is harmful to very much, gearbox is excessively cold, heat dissipating capacity increases, oil consumption is risen, the gearbox rough running, decrease in efficiency.For above-mentioned phenomenon, the automobile gearbox cooling system adopts the single cycle formula more at present, its type of cooling is single, be generally air-cooled cooling system or the cooling system of water-cooled, along with improving constantly that automobile requires gearbox, the defects such as traditional cooling system for speed changing box existence form is single, efficiency is low, performance boost insufficient space, be also one of factor limited gearbox reliable operation under high moment of torsion operating mode, and for gearbox, certain inhibition has been played in development.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of cooling system for speed changing box, its project organization is reasonable, good cooling results.
The utility model solves the technological scheme that its technical problem adopts: a kind of cooling system for speed changing box, comprise water tank, oil radiator, the water jacket that is located at the water pump on motor and is located at the oil radiator top, described tank top is communicated with the major cycle pipe, water tank bottom is communicated with pump water inlet, the pump water inlet the other end is connected with water pump, the water pump the other end is communicated with the short circle pipe, short circle pipe one side is provided with fan, the other end of short circle pipe is communicated with thermostat, thermostat by pipeline respectively with oil radiator, water jacket and major cycle pipe are connected.
Described tank top has swelling water tank by pipeline communication, and the other end of swelling water tank is connected with the major cycle pipe by pipeline.
The beneficial effects of the utility model are: described a kind of cooling system for speed changing box, adopt the cooling system of this kind of design, and can realize gearbox is carried out to cooling purpose fast, project organization is reasonable.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the overall structure schematic diagram of a kind of cooling system for speed changing box described in the utility model.
Accompanying drawing acceptance of the bid score state as follows: 1, water tank, 2, oil radiator, 3, water pump, 4, the major cycle pipe, 5, pump water inlet, 6, the short circle pipe, 7, fan, 8, thermostat, 9, water jacket, 10, swelling water tank.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of cooling system for speed changing box as shown in Figure 1, comprise water tank 1, oil radiator 2, the water jacket 9 that is located at the water pump 3 on motor and is located at oil radiator 2 tops, water tank 1 top is communicated with major cycle pipe 4 and by pipeline communication, swelling water tank 10 is arranged, the other end of swelling water tank 10 is connected with major cycle pipe 4 by pipeline, water tank 1 bottom is communicated with pump water inlet 5, pump water inlet 5 the other ends are connected with water pump 3, water pump 3 the other ends are communicated with short circle pipe 6, short circle pipe 6 one sides are provided with fan 7, the other end of short circle pipe 6 is communicated with thermostat 8, thermostat 8 by pipeline respectively with oil radiator 2, water jacket 9 and major cycle pipe 4 are connected.
A kind of cooling system for speed changing box of the present utility model, after engine start, short circle pipe 6 is opened, water pump 3 arrives each branch road to the water pump in water tank 1, then cooling water flow, toward thermostat, flow back into again cylinder cap, the cylinder body water jacket of motor, when major cycle pipe 4 is opened, water pump 3 is transported to each branch road to cooling water, and cooling water flows to oil radiator 2 by thermostat 8.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, the relevant staff can, in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to the claim scope.
