Abstract
The utility model relates to a braking camshaft, which not only can directly drive an intake valve and an exhaust valve, but also is high in bearing strength and simple in structure. The braking camshaft comprises a camshaft, a raised head of the camshaft is S-shaped, a continuous arc-shaped edge is arranged at the edge of the S-shaped raised head, and knurling is knurled at the arc-shaped edge. The braking camshaft has the advantages of 1, novel, reasonable and high-strength structure, and 2, uniform stress on the raised head 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 brake camshaft 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, a kind of brake 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 brake camshaft, it comprises camshaft, and described camshaft plush copper is S-shaped, and S shape plush copper limit is continuous arc limit, and arc has rolled annular knurl on the limit.
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 brake 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 brake camshaft, it comprises camshaft 1, and described camshaft plush copper 2 is S-shaped, and S shape plush copper limit is continuous arc limit, and annular knurl 3 on the arc limit.
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)
1. brake camshaft, it comprises camshaft, it is characterized in that: described camshaft plush copper is S-shaped, and S shape plush copper limit is continuous arc limit, and arc has rolled annular knurl on the limit.
2. brake camshaft according to claim 1 is characterized in that: 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.
