Abstract
The utility model relates to a braking S spline protruded-insertion type cam shaft, which not only can directly drive an intake valve and an exhaust valve, but also has high stress strength and a simple structure. A raised head of the cam shaft is in an S shape, the side of the S-shaped raised head is a continuous arc-shaped side, and the middle of the raised head is provided with a bolt hole; a shaft rod is a hollow shaft rod, an inner cavity at one end of the hollow shaft rod is sheathed with a screw thread and is connected with the raised head through a bolt, the tail part at the other end of the shaft rod is provided with a spline, and the end face of the spline adopts protruded-insertion. The braking S spline protruded-insertion type cam shaft has the advantages that: (1) the structural design is novel and reasonable, and the strength is high; (2) the raised head is stressed uniformly, and the service life is long; and (3) the shaft rod adopts the hollow shaft rod, so that the weight is light, the processing cost is low, and the quick assembly is convenient.
Description
Technical field
The utility model relates to a kind ofly can directly drive the inlet and outlet door, has the force intensity of being subjected to height again, and the protruding slotting formula camshaft of a kind of braking S spline simple in structure belongs to camshaft and makes the field.
Background technique
CN201310579Y, title " brake cam of automobile axle ", this mechanism comprises that cam is connected with axostylus axostyle, and axostylus axostyle and adjustment arm connecting end peripheral hardware involute splines are characterized in that axostylus axostyle is a hollow-core construction, and axostylus axostyle center and cam rotating center are on same straight line.Its deficiency: the one, the limit of spindle nose is non-arc limit, not only causes spindle nose not smooth with cooperating of other parts, and the spindle nose unbalance stress; The 2nd, axostylus axostyle adopts hollow-core construction and spindle nose welding, and its weld strength is low, easy separating between generation axostylus axostyle and spindle nose when stressed.
The model utility content
Purpose of design: avoid the deficiency in the background technique, design and a kind ofly can directly drive the inlet and outlet door, have the force intensity of being subjected to height again, the protruding slotting formula camshaft of a kind of braking S spline simple in structure.
Design proposal: in order to realize above-mentioned purpose of design.1, the plush copper limit of camshaft is the design on continuous arc limit, is one of technical characteristics of the present utility model.The purpose of doing like this is: the limit of spindle nose is the arc limit, not only can guarantee the good fit of spindle nose and other parts, and can guarantee that spindle nose is stressed evenly.2, the axostylus axostyle afterbody is the design of spline, is two of technical characteristics of the present utility model.The purpose of doing like this is: realized the matched well between camshaft and the hand regulation arm, guaranteed the reliable adjustment of hand regulation arm.3, the spline end face is protruding slotting design, is three of technical characteristics of the present utility model.The purpose of doing like this is: this protruding inserts is matched with spline, guarantee and hand regulation arm between reliable coupling.4, axostylus axostyle adopts the design of hollow axis pole, is four of technical characteristics of the present utility model.The purpose of doing like this is: both alleviated the weight of axostylus axostyle, reduced manufacture cost again, be convenient to quick assembling simultaneously again.
Technological scheme: the protruding slotting formula camshaft of a kind of braking S spline, it comprises camshaft, and described camshaft plush copper is S-shaped, and S shape plush copper limit is continuous arc limit, and the plush copper center has bolt hole; Described axostylus axostyle is a hollow axis pole, and hollow shaft one end inner chamber is with screw thread and is connected with plush copper by bolt, and axostylus axostyle the other end axostylus axostyle afterbody is a spline, and the spline end face is protruding inserting.
The utility model is compared with background technique, the one, the structural design novelty, rationally, intensity is high; The 2nd, plush copper is stressed evenly, long service life; The 3rd, axostylus axostyle adopts hollow axis pole, and is not only in light weight, processing charges is low, and is convenient to quick assembling.
Description of drawings
Fig. 1 is the structural representation of the protruding slotting formula camshaft of a kind of S of braking spline.
Fig. 2 is the left TV structure schematic representation of Fig. 1.
Fig. 3 is the structural representation of axle end among Fig. 1.
Embodiment
Embodiment 1: with reference to accompanying drawing 1-3.The protruding slotting formula camshaft of a kind of braking S spline, it comprises camshaft 1, and described camshaft 1 plush copper 2 is S-shaped, and S shape plush copper 2 limits are continuous arc limit, and plush copper 2 centers have bolt hole; Described axostylus axostyle is a hollow axis pole, and hollow shaft one end inner chamber is with screw thread and is connected with plush copper 2 by bolt 5, and axostylus axostyle the other end axostylus axostyle afterbody is a spline 3, and the spline end face is protrudingly to insert 4, and protruding slotting 4 cooperate with the grafting of spline end face.Described S shape plush copper is symmetrically distributed, and axle end is connected with S shape plush copper center and S shape plush copper is symmetrically distributed in the axostylus axostyle two ends.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to restriction of the present utility model; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (2)
