Abstract
The utility model discloses a box body of an automobile speed changing box. The box body of the automobile speed changing box comprises a speed changing box body which is formed in an integrated casting mode. An input shaft hole is formed in the lower portion of one end of the speed changing box body, and a differential mechanism installation hole is formed in the upper portion of the speed changing box body. A middle shaft installation hole is formed in one side of the input shaft hole. The outer edge of the input shaft hole, the outer edge of the differential mechanism installation hole and the middle shaft installation hole are connected with one another to form protruding sealing steps. A plurality of fixing holes are formed in the sealing steps. The box body of the automobile speed changing box has the advantages of being formed in an integrated casting mode so as to be good in sealing performance and stronger in integrated bearing capacity, being provided with the sealing steps turned on an end face so as to be favorable to assembling and sealing and prevent oil leakage of the box body, and being simple in structure, safe, reliable, and more convenient to machine.
Description
Technical field
The utility model relates to gearbox technical field, refers in particular to a kind of vehicle speed variation box body.
Background technique
Along with socioeconomic development, automobile is more and more universal.Vehicle is at starting, idling parking, low speed or run at high speed, accelerate, slow down, climbing and reversing etc., all require driving force and the speed of a motor vehicle of automobile in sizable scope, to change, and the output torque and rotational speed excursion of the reciprocating engine extensively adopting is at present less.For the driving conditions that adapts to often change, make motor (power is higher, oil consumption is lower) work under favourable operating mode simultaneously, in transmission system, be provided with speed changer.Speed changer, by changing velocity ratio, expands the excursion of driving wheel torque and rotational speed, with the driving conditions that adapts to often change, makes motor work under compared with operating mode high and that oil consumption is lower in favourable speed simultaneously; Existing gear box mostly is the right and left die sinking, the inner chamber forming at two-half die packs the parts such as axle tooth, differential mechanism into, then two-half die is bolted to formation gearbox, adopts split type structure to exist processing cost high, poor sealing performance, the shortcoming such as strength is poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the gear box of a kind of simple in structure, good airproof performance, the cast molding of employing one is provided.
For achieving the above object, technological scheme provided by the utility model is: a kind of vehicle speed variation box body, it includes gearbox main body, gearbox main body adopts integral cast moulding, bottom, gearbox main body one end is provided with input shaft axis hole, top is provided with differential mechanism mounting hole, and input shaft axis hole one side is provided with jack shaft mounting hole; The outer rim of input shaft axis hole, differential mechanism mounting hole and jack shaft mounting hole is coupled to each other and forms protruding sealed step; Sealed step is provided with several fixed holes.
Described fixed hole distributes successively along sealed step profile.
Described gearbox main body one side is provided with several horizontal shaft holes, and opposite side is provided with the inclined shaft hole of inclination.
Described gearbox bottom part body is arc mechanism, and top-slitting also seals by case lid.
The utility model has the advantage of: adopt one cast molding, good airproof performance, overall ability to bear is stronger; End face car goes out sealed step, is conducive to fitting tight, prevents casing leakage of oil; This programme simple in structure, safe and reliable, processes convenient.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: referring to accompanying drawing 1, gear box described in the present embodiment includes gearbox main body 1, it is characterized in that: gearbox main body 1 adopts integral cast moulding, gearbox main body 1 one sides are provided with several horizontal shaft holes 7, and opposite side is provided with the inclined shaft hole 8 of inclination.Gearbox main body 1 bottom, one end is provided with input shaft axis hole 4, and top is provided with differential mechanism mounting hole 3, and input shaft axis hole 4 one sides are provided with jack shaft mounting hole 2; The outer rim of input shaft axis hole 4, differential mechanism mounting hole 3 and jack shaft mounting hole 2 is coupled to each other and forms protruding sealed step 5; Sealed step 5 is provided with several fixed holes 6.Fixed hole 6 distributes successively along sealed step 5 profiles.Gearbox main body 1 bottom is arc mechanism, and top-slitting also seals by case lid.Adopt one cast molding, good airproof performance, overall ability to bear is stronger; End face car goes out sealed step, is conducive to fitting tight, prevents casing leakage of oil.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
