Abstract
The utility model discloses a braking cam shaft with a threaded joint. The cam shaft comprises a cam, a rod part and a tail part, wherein the cam, the rod part and the tail part are connected one another; the cam is S-shaped; the rod part is provided with a plurality of curved surfaces and curved grooves; the tail part is provided with the threaded joint; the semi-diameter of the threaded joint is less than that of the rod part; due to the adoption of the braking camshaft with the threaded joint, a braking mechanism is connected closely, the cam shaft is easy to demount, can be connected closely and firmly, and is not likely to release, and therefore safer and more reliable guarantee is provided for the running of a vehicle.
Description
Technical field
The utility model relates to car brakeing accessory field, relates in particular to a kind of camshaft with teeth joint.
Background technique
Many these A Yong drum brakes of automobile brake, drum brake is the braking system of early stage design, its brake design has just been used on carriage for 1902.Camshaft is that it connects the arrestment mechanism of adjusting arm and brake shoe, by camshaft transmission external force to brake shoe, make brake shoe to inner rotary, the friction plate of outer surface presses against on the inner cylindrical surface of brake drum, drum is produced to friction torque to reach braking effect, a kind of brake camshaft of the prior art.The camshaft using now adopts pin-and-hole to be connected with the arrestment mechanism of brake shoe adjusting arm, cause dismantling, assemble the amount of labour large, and make to connect insecure, and can have influence on the validity of adjusting gap between arm adjustable brake drum and brake shoe, to driving, bring potential safety hazard.
Model utility content
The utility model provides a kind of camshaft with teeth joint, the technical problem that solve be to overcome above-mentioned middle dismounting inconvenience, the assembling amount of labour large, connect insecure, untight deficiency.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: the brake camshaft with teeth joint is comprised of cam, bar portion and afterbody, and described cam, bar portion are sequentially connected with afterbody, and described afterbody is provided with teeth structural joint.
Further, described cam face is S-type.
Further, described bar portion is provided with multiple curved surfaces and crank slot.
Further, the number of teeth of described teeth structural joint is 37 teeth.
Further, described teeth structure is also provided with one section of shaft part, is provided with crank slot and curved surface.
Further, the radius of described teeth structural joint is less than the radius of bar portion.
From the above-mentioned description to the utility model structure, compared to the prior art, the utlity model has following advantage: the utility model closely connects arrestment mechanism by the brake camshaft of teeth joint, dismounting is simple, connect close and firm, difficult drop-off, to automobile running, provides more safe and reliable assurance.
