Description

A kind of driving axle bracket of automobile

technical field

The utility model belongs to the technical field of automobiles, and relates to a driving half-shaft bracket of an automobile.

Background technique

The drive shaft is one of the important parts in the car transmission system, and it is the shaft that transmits torque between the gearbox reducer and the drive wheel. The drive shaft of most passenger cars consists of a left drive half shaft and a right drive half shaft. In the vehicle design stage, if the left and right driving half shafts are required to be designed with unequal lengths, problems such as acceleration deviation and drive shaft resonance are prone to occur on the relatively longer side of the driving half shaft. At this time, it is necessary to equip the intermediate bracket on the drive half shaft on the longer side to effectively support the shaft to prevent problems such as acceleration deviation and resonance.

For example, the Chinese patent [application number: 201120130429.4; authorized announcement number: CN 202088814U] discloses a constant velocity drive shaft installation structure, including a bracket fixed on the engine block, a bearing seat detachably connected to the bracket, and a The bearing assembled with the high-speed drive shaft, the bearing is fixed in the bearing seat through a circlip, and the bearing seat is detachably connected to the bracket through the connecting piece, when the bearing is fixed in the bearing seat, one end of the constant-speed drive shaft Pass through the bearing housing and bracket. The outer side of the bearing seat has a retaining edge, and a connecting hole is provided on the retaining edge, and a mounting hole corresponding to the connecting hole is provided on the bracket. When the bearing seat is connected to the support, the connecting piece is located in the connecting hole and the mounting hole.

At present, the existing drive half-shaft brackets, including the brackets in the installation structure of the above-mentioned constant velocity drive shaft, have the following defects: 1. The position design of the holes used to connect with the bearing seat or the drive shaft connecting plate can only be matched with each other; A drive shaft with poor versatility; at the same time, the hole is generally a full thread or a through hole with a welded nut. This method requires one hand to hold the drive shaft and the other hand to tighten the bolts during installation, which is not conducive to the drive half shaft. Installation; and, if it is a through hole, it cannot meet the installation requirements of the double-headed stud; 2. When connecting with the engine block, it is generally a positioning hole and two round holes that are larger than the positioning hole. This form is not conducive to Positioning, it is easy to cause the vibration of the drive shaft, and it is inconvenient to install.

Through the design of the position and quantity of the connecting holes, this bracket can be used to connect a variety of different driving half shafts. According to different installation needs, different positions of connecting holes can be selected. When the driving half shaft is inserted into the transmission, the driving half shaft The hole on the connection plate or the hole on the bearing seat coincides with the connection hole at the corresponding position of the bracket, which solves the problem of misassembly; and, combined with the structural design of the connection hole, the bracket is convenient for installation in different threaded connection forms and can be matched with different The unique engine and transmission combination has good versatility and easy assembly.

In the above-mentioned driving axle bracket of the automobile, one side of the body has a plate-shaped fixing part 1, and the fixing part 1 has a positioning circular hole and a positioning waist-shaped hole, and the width of the positioning waist-shaped hole is Same diameter as the positioning hole. The positioning round hole and the positioning waist hole are used for the connection between the bracket and the engine block. Through the design of the above waist hole, the accuracy of positioning is ensured, making the installation and connection between the bracket and the automobile engine more convenient.

In the above-mentioned driving axle bracket of the automobile, the other side of the body has a plate-shaped fixing part 2, and the fixing part 2 has an auxiliary fixing round hole on the second fixing part. Through the above design of the auxiliary fixing round hole, the installation of the bracket can be more firm and stable.

In the above-mentioned driving axle bracket of the automobile, the upper and lower ends of the body have connecting arms extending outwards respectively, and an arc-shaped relief opening is formed between the two connecting arms. The connecting holes are located at the ends of the corresponding connecting arms. Through the design of the above-mentioned arc-shaped relief opening, no interference will occur when the bracket and the driving half shaft are installed together, and the installation is convenient.

Compared with the prior art, the driving axle bracket of the automobile has the following advantages: the bracket is designed through the position, quantity and structure of the connecting holes, as well as the design of the positioning round hole, the positioning waist hole and the auxiliary fixing round hole, so that The bracket can be applied to different power assembly combinations and different threaded fasteners, has good versatility, and is easy to assemble.
