Description

The automobile ordinary geartrain hydraulic speed transmission casing

Technical field

The utility model belongs to a kind of gearbox casing, refers in particular to a kind of automobile ordinary geartrain hydraulic speed transmission casing.

Background technique

Hydraulic transmission gearbox generally is made up of fluid torque converter and gearbox.It is handled multi-disc wet clutch by electrichydraulic control and realizes gear shift.Gearbox is made up of casing, case lid, inner oil duct and outside radiating fin.Casing, case lid support each gear axle, and the outside radiating fin can reduce the inside temperature of gearbox, play thermolysis, can increase the intensity of casing simultaneously again.

Bottom in the casing is equivalent to oil sump, stores hydraulic transmission oil.When power shfit, oil must circulate in inside, therefore, oil duct need be set in casing.In the prior art, the inside oil duct of gearbox is realized by machining hole, during manufacturing, Kong Yukong is linked up, and perhaps links up with pipe behind the machining hole again, forms complete oil duct in casing.Pipe takies very large space in casing, make the box shape size become big; The hole of processing is influenced by the blank internal soundness, occurs seepage sometimes, causes internal oil pressure to descend, even breaks down to cause and do not have a shelves phenomenon.Processing technology complexity, machining period are grown in addition, expense is many, assembling is complicated, the maintenance trouble breaks down.

Summary of the invention

The purpose of this utility model is to design a kind of automobile ordinary geartrain hydraulic speed transmission casing, and in this casing, pipeline is embedded in the inwall of casing, so occupation space is less, has also avoided problems such as seepage simultaneously.

Technological scheme according to the utility model provides forms the space that holds driving mechanism in casing and case lid, it is characterized in that: the inwall at casing has pipeline, and described pipeline is embedded in the inwall of casing when the casting box blank.

The inwall built-in metal pipeline of the casing of making at aluminum alloy.The top of case lid is provided for installing the axis hole of output shaft, be provided for installing the axis hole of first jack shaft in the bottom of case lid, be provided for installing the axis hole of reverse gear shaft in a side of case lid, be provided for installing the axis hole of second jack shaft at the opposite side of case lid, on the opposite walls corresponding to the axis hole of output shaft on the casing, be provided for the flange edge that docks with the output terminal of motor, the centres of the center of described flange edge and the axis hole of output shaft.

Described casing comprises bottom surface, end face, left surface, back and front, and described case lid is positioned at the right side of casing, and the bottom in the casing is provided with oil sump, at the inwall of the left surface of casing the built-in oil duct of oil pump inlet port is set, and filter is arranged in oil sump.

Described pipeline comprises: the built-in pipe on the I shelves clutch casing, built-in pipe on the III shelves clutch casing, the built-in pipe of torque-converters filler opening, the built-in pipe of locking shelves lockup clutch filler opening, the built-in pipe on the II shelves clutch casing, the built-in pipe on the reverse clutch casing, built-in pipe on the IV shelves clutch casing, the built-in pipe of torque-converters oil outlet, the built-in pipe of oil pump inlet port, the built-in oil-piping of oil pump oil outlet.

The utility model has the advantages that: the oil duct of gearbox inside is to make the Cuprum alloy pipeline by designing requirement in advance, pre-buriedly when rough-cast then enters, and the outside be cannot see, and also need not process.This oil duct takes up room less in casing, can be along the ingenious design of cabinet wall, and pipeline is short and relatively rationally compact, does not need the processing technology hole.As long as casing, case lid process set of planes altogether, each oil duct just can be connected mutually, and mutual noninterference between each oil duct seepage can not occur.And each oil duct can be connected with each gear oil cylinder by the control of valve and finish gear shift, connects with oilhole, and sufficient lubrication reduces the box house temperature.
