Abstract
The utility model relates to a hollow shaft lever camshaft, which can directly drive an intake valve and an exhaust valve and has high force bearing capacity and simple structure. The camshaft comprises a camshaft, wherein the cam head of the camshaft is S-shaped, the sides of the S-shaped cam head are continuous arc-shaped sides, and a bolt hole is formed at the center of the cam head; and the shaft lever is a hollow shaft lever, the inner cavity of one end of the hollow shaft is sleeved with a screw thread and is connected with the cam head through a bolt, and an annular groove is arranged at the other end of the shaft lever. The hollow shaft lever camshaft has the advantages as follows: (1) the structural design is novel and reasonable and the strength is high; and (2) the cam head has uniform force bearing and long service life.
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 a kind of hollow axis pole camshaft simple in structure belongs to camshaft and makes the field.
Background technique
CN201310579Y, title " automobile hollow axis pole camshaft ", this mechanism comprises that cam is connected with axostylus axostyle, 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, a kind of hollow axis pole camshaft 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 design of annular knurl on the arc limit is two of a technical characteristics of the present utility model.The purpose of doing like this is: this annular knurl limit friction factor is big, and the parts that can match with it form reliable cooperation.
Technological scheme: a kind of hollow axis pole camshaft, 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 the axostylus axostyle the other end has annular groove.
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.
Description of drawings
Fig. 1 is a kind of structural representation of hollow axis pole camshaft.
Fig. 2 is the left TV structure schematic representation of Fig. 1.
Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.A kind of hollow axis pole camshaft, it comprises camshaft 1, and described camshaft 1 plush copper 2 is S-shaped, and S shape plush copper limit is 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 4, and the axostylus axostyle the other end has annular groove 3.
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.
