Abstract
The utility model discloses a kind of lightweight camshafts, including cam, mounting rod and splined shaft, it is characterized in that, the cam includes S-cam and the fixture block that connect with S-cam one end, one end of the mounting rod of hollow setting, the other end and spline axis connection of the mounting rod are protruded into one end of the fixture block.The utility model is that brake camshaft is changed to hollow structure by solid construction, while proof strength, also saves material, reduces the production cost, and the utility model quality reduces, and is conducive to the demand of vehicle lightweight development.
Description
Technical field
The utility model belongs to field of automobile parts and components, specifically a kind of lightweight camshaft.
Background technique
The brake cam that domestic commercial vehicle, car, military vehicle, tractor truck and part wheeled vehicle use at present
Axis forges blank-making technology using bar, especially for brake camshaft used in driving axis and trailer axle assembly, because
The limitation cam shaft length of bulk is especially long, leads to the increase of weight, processing cost and the cost of raw material, is unfavorable for vehicle
The demand of lightweight development.
Summary of the invention
Brake camshaft is changed to hollow structure by solid construction by the utility model, proof strength and can be saved
Material reduces weight.
To achieve the above object, the utility model includes cam, mounting rod and splined shaft, which is characterized in that the cam
Including S-cam and the fixture block connecting with S-cam one end, the one of the mounting rod of hollow setting is protruded into one end of the fixture block
End, the other end and spline axis connection of the mounting rod.
Preferably, the end face of the fixture block and an end face of mounting rod are welding.
Preferably, the both ends outer wall of the mounting rod is respectively brake lining matching surface and bracket bushing cooperation table
Face.
With the above arrangement, the utility model is that brake camshaft is changed to hollow structure by solid construction, guaranteeing by force
While spending, material is also saved, is reduced the production cost, and the utility model quality reduces, is conducive to vehicle lightweight hair
The demand of exhibition.
Detailed description of the invention
The utility model is described further now in conjunction with attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model cam.
In figure: 1, cam, 11, S-cam, 12, fixture block, 2, mounting rod, 3, splined shaft, 4, brake lining cooperation table
Face, 5, bracket bushing matching surface.
Specific embodiment
As shown in Figure 1, 2, the utility model includes cam 1, mounting rod 2 and splined shaft 3, which is characterized in that the cam 1
Including S-cam 11 and the fixture block 12 connecting with 11 one end of S-cam, the peace of hollow setting is protruded into one end of the fixture block 12
One end of bar 2 is filled, the other end of the mounting rod 2 is connect with splined shaft 3.
Further, the end face of the fixture block 12 and an end face of mounting rod 2 are welding.
Further, the both ends outer wall of the mounting rod 2 is respectively brake lining matching surface 4 and the cooperation of bracket bushing
Surface 5.
With the above arrangement, S-cam 11 is matched with brake wheel after the utility model is to be assembled on axle assembly
It closes, brake lining matching surface 4 and bracket bushing matching surface 5 cooperate with brake lining and bracket bushing, splined shaft 3
With adjustment arm cooperation, for transmitting brake actuation power, in turn, the utility model by the blank preparation process of brake camshaft also into
Row, which is optimized and revised, is changed to welding molding by bar solid forging, and cam shaft head still uses die-forging forming, and camshaft bar portion uses
Then hollow circular-tube is machined out by the two welding fabrication when base.Using the preparation process, 1 axis of drive axle cam is single
Drop weighs about 20%.
