Technical Field

The invention relates to the technical field of vehicle driving shaft fixing, in particular to a driving shaft fixing support.

Background

The arrangement scheme of the driving shaft and the power assembly of some vehicle types requires that the driving shaft adopts a structural form of lengthening the spline shaft at the movable end, and at the moment, a supporting structure of the spline shaft, namely a driving shaft mounting bracket, needs to be added. As a separate supporting structure, the single-support-type vehicle is generally only used in cooperation with a driving shaft, namely, the installation and fixation of other parts are realized by an additional separate fixing structure, which causes the problems that the number of the existing vehicle internal parts is too large and the structure is too complex to a certain extent, and also influences the production and assembly efficiency of the vehicle.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provides a driving shaft fixing support which reasonably integrates a charger support mounting point, can effectively reduce the number of charger mounting accessories, simplifies the internal structure of a vehicle, reduces the overall weight and improves the assembly efficiency.

The purpose of the invention is realized by the following technical scheme:

the utility model provides a drive shaft fixed bolster, includes the main part, the main part is equipped with the drive shaft mounting hole, the both sides that the main part is relative are equipped with machine support mounting portion and link up portion respectively, machine support mounting portion one side is equipped with first support fixed plate perpendicularly, the one end that the main part was kept away from to link up portion is equipped with second support fixed plate perpendicularly, all be equipped with the fixed orifices on first support fixed plate and the second support fixed plate, machine support mounting portion keeps away from the one end of main part is equipped with machine support mounting hole.

The charger bracket mounting point is reasonably integrated on the driving shaft fixing bracket, and the structural weight is reasonably distributed on two sides of the driving shaft mounting hole, so that the whole bracket is more uniformly stressed, and the structural strength is more reliable. The mounting structure of the charger support is simplified on the whole, the internal structure and the weight of the vehicle are reduced, and the vehicle assembly efficiency is improved.

Preferably, a plurality of first lightening holes are formed in one side, close to the main body part, of the charger support mounting part, and the direction of the first lightening holes is the same as that of the driving shaft mounting holes. The first lightening holes are holes with small hole diameters, the shock absorption effect can be effectively guaranteed by arranging the first lightening holes, and meanwhile, the structural strength is easier to ensure in the form of the small holes.

Preferably, the engagement portion is provided with a second lightening hole, and the direction of the second lightening hole is perpendicular to the direction of the drive shaft mounting hole. Since no mounting hole is required on the connecting part, the weight-reducing effect can be improved by designing a larger second weight-reducing hole.

Preferably, the second bracket fixing plate has a height greater than that of the main body portion, and the engagement portion has an arc-shaped transition surface. The arc-shaped transition surface enables the main body part to be connected with the second support fixing plate more firmly.

Preferably, the second lightening holes are trapezoidal in shape to accommodate the structure of the joint part. The structure further improves the weight reduction effect.

In the present invention, it is preferable that the main body is connected to the first bracket fixing plate. The structure improves the structural strength and stability of the first bracket fixing plate.

Preferably, the first bracket fixing plate is provided with one driving shaft mounting hole, and the second bracket fixing plate is provided with two driving shaft mounting holes. The first bracket fixing plate is arranged on one side of the charger bracket mounting part, so that the first bracket fixing plate is small in shape and only provided with one driving shaft mounting hole to ensure the structural strength of the first bracket fixing plate; and the second support fixed plate is bigger, so set up two drive shaft mounting holes, guarantee the installation stability.

The invention has the advantages that: the structural design is simple, the charger support mounting point is reasonably integrated on the driving shaft mounting support, the internal structure of the vehicle is simplified, the overall weight is reduced, and the vehicle assembly efficiency is improved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The utility model provides a drive shaft fixed bolster, includes main part 1, main part 1 is equipped with drive shaft mounting hole 2, main part 1 relative both sides are equipped with machine support mounting portion 3 and linking portion 4 that charge respectively, 3 one side of machine support mounting portion is equipped with first support fixed plate 5 perpendicularly, the one end that the main part was kept away from to linking portion 4 is equipped with second support fixed plate 6 perpendicularly, all be equipped with fixed orifices 7 on first support fixed plate 5 and the second support fixed plate 6, machine support mounting portion 3 keeps away from the one end of main part 1 is equipped with machine support mounting hole 8 that charges.

The charger bracket mounting point is reasonably integrated on the driving shaft fixing bracket, and the structural weight is reasonably distributed on two sides of the driving shaft mounting hole, so that the whole bracket is more uniformly stressed, and the structural strength is more reliable. The mounting structure of the charger support is simplified on the whole, the internal structure and the weight of the vehicle are reduced, and the vehicle assembly efficiency is improved.

Specifically, one side of the charger bracket mounting part 3, which is close to the main body part 1, is provided with a plurality of first lightening holes 9, and the direction of the first lightening holes 9 is the same as that of the driving shaft mounting holes 2. The first lightening holes are holes with small hole diameters, the shock absorption effect can be effectively guaranteed by arranging the first lightening holes, and meanwhile, the structural strength is easier to ensure in the form of the small holes. And the joint part 4 is provided with a second lightening hole 10, and the direction of the second lightening hole 10 is perpendicular to the direction of the driving shaft mounting hole 2. Since no mounting hole is required on the connecting part, the weight-reducing effect can be improved by designing a larger second weight-reducing hole.

In addition, the height of the second bracket fixing plate 6 is greater than that of the main body part 1, and the joint part 4 has an arc-shaped transition surface 11. The arc-shaped transition surface enables the main body part to be connected with the second support fixing plate more firmly.
