Abstract
The utility model relates to a device for controlling the oil level of an automobile gear box, which comprises an oil level pipe (1) which is internally hollow, and an oil drain plug (3) arranged below the oil level pipe. The centers of the oil level pipe (1) and the oil drain plug (3) are concentric. The device for controlling the oil level of an automobile gear box can play the role of controlling the oil level in the gear box while draining the gear box; the device can effectively solve the problems that the use performance of the gear box is influenced by that the lubrication is influenced and the fuel charge is difficult to control due to the reduction of the oil level caused by volatilization during the running of the gear box, and the like, can well control the oil level in the gear box, and have low cost.
Description
Technical field
The utility model relates to the speed changer technical field, is a kind of device of Control of Automobile speed changer oil level height specifically.
Background technique
In the running of speed changer, the speed changer transmission oil plays considerable effect: lubricated, and heat radiation etc.Functions such as that the employed transmission oil ATF of automatic transmission has concurrently is lubricated, hydraudynamic drive, cooling, hydraulic control, cleaning.ATF not only as the working medium that transmits energy, also plays the effect of lubrication friction pair simultaneously, reduce the friction surface of heat transfer medium control temperature, prevent sintering.The usability and the life-span thereof that how much directly have influence on speed changer of its oil mass.
Along with running up of motor car engine, speed changer interior oil temperature as the automobile power transmitting set can rise to 100 ℃, even higher, the minimizing of also will inevitably volatilizing of its fluid will inevitably cause the minimizing of speed changer fluid owing to the gear engagement running waits other reason simultaneously.Speed changer also needs to change oil in maintenance or maintenance process, if there is not this time special-purpose oil-filling device can cause transmission oil excessive or not enough, these all can have influence on the usability of speed changer.
Summary of the invention
The utility model has solved the above-mentioned problem that prior art exists, a kind of device of Control of Automobile speed changer oil level height is provided, it is reasonable in design, simple in structure, with low cost, can effectively control simultaneously the volume read-out of speed changer, speed changer can effectively be moved, improve the life-span of speed changer.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of device of Control of Automobile speed changer oil level height, it is characterized in that described device comprises level height pipe inner hollow, and with the purge cock that places its underpart, the centres of this level height pipe and purge cock.This level height pipe adopts the casting integrated moulding of plastic material, and purge cock adopts metal material, and the design length of level height pipe is installed in its top, back and identical being as the criterion of the required level height of speed changer on the housing with the level height pipe.The purge cock of general speed changer all at the lowest part of its speed changer so that drain the oil thoroughly, and perpendicular to horizontal plane.When refueling to speed changer, angular orientation when speed changer is put into its use, generally be that purge cock and level height pipe are designed to perpendicular to horizontal plane, control its volume read-out, make it reach the fluid amount that speed changer needs thereby just overflowed to be as the criterion in the level height pipe with fluid during oiling.
As preferably, on the described level height pipe step is arranged, on the outer side surface of intermediate portion, be provided with the height pipe thread.This height pipe thread is used for connecting housing.
As preferably, on the described purge cock step is arranged, Bu Fen outer side surface is provided with the plug screw screw thread in the above.This plug screw screw thread is to be used for fixing the connection housing, plays the effect of draining the oil, and also can seal simultaneously the fluid that leaks out in the level height pipe.
As preferably, the outer diameter of the bottom part of described level height pipe is less than the purge cock inner diameter of part topmost.Can make level height pipe lower end insert the top of purge cock like this.
The utility model is skillfully constructed, and makes it have following beneficial effect compared with the prior art:
1, the level height pipe adopts plastics casting once-through, and the volume production cost is low, is installed on the housing easy accessibility during assembling by screw thread;
2, reasonable in design, simple in structure, with low cost, the while can effectively be controlled the volume read-out of speed changer, and speed changer can effectively be moved, and improves the life-span of speed changer.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment.See Fig. 1, the utility model comprises level height pipe 1 and places the purge cock 3 of its underpart that the outer diameter of level height pipe 1 bottom part can make level height pipe lower end insert the top of purge cock less than the inner diameter of purge cock 3 the top parts; Level height pipe 1 is by the plastics casting, and purge cock 3 is metal; On this level height pipe 1 step is arranged, be provided with height pipe thread 2 on the outer side surface of intermediate portion, on the purge cock 3 step is arranged, Bu Fen outer side surface is provided with plug screw screw thread 4 in the above.And level height pipe 1 inner hollow is connected on the housing by height pipe thread 2, and purge cock 3 is fixed on the housing by plug screw screw thread 4.
It is apparent to one skilled in the art that the utility model can be changed into multiple mode, and such change is not thought and broken away from scope of the present utility model.What all were such will be included within the scope of this claim the conspicuous modification of described those skilled in the art.
