Abstract
The invention discloses a bolt fastening connection device of a drive shaft and an automobile frame. The bolt fastening connection device of the drive shaft and the automobile frame comprises mounting holes which are formed in the drive shaft and the automobile frame in corresponding mode, and square head bolts which are disposed in the mounting holes in penetrating mode, wherein stop blocks are welded among the mounting holes in the automobile frame, and during the installation process of the square head bolts, the mounting holes in the automobile frame are aligned with the mounting holes in the drive shaft, the square head bolts are inserted into the mounting holes in the automobile frame and in the drive shaft, and one side face of the head of each square head bolt is contacted with the side face of one stop block. The bolt fastening connection device of the drive shaft and the automobile frame further comprises self-locking nuts matched with the square head bolts in locking mode. According to the bolt fastening connection device of the drive shaft and the automobile frame, the square head bolts are used, the stop blocks are welded on the automobile frame, the bolt heads are contacted wit the stop blocks when the square head bolts are installed, and therefore each square head bolt can not revolve around the own axis, and furthermore due to the fact that the self-locking nuts are used, only one person can perform assembly, manpower is saved, looseness prevention is facilitated due to the stop blocks and the self-locking nuts after the square head bolts are installed, and hidden danger of easily loosing is eliminated.
Description
technical field:
The present invention relates to a kind of ransaxle and carriage bolt fastening-connecting device, it belongs to interconnection technique field.
background technique:
In prior art as shown in Figure 1, ransaxle 1 is used hexagon head bolt 3 to be connected with vehicle frame 2, when installing, it need a people with spanner, to locate up, one people below with air inflating machine for dismantling tyre tightening nut 4, this mode waste of manpower resource greatly and being prone to accidents, and be plain nut owing to selecting nut, without locking measure, cause in the future and connect easily and become flexible.
Therefore, the necessary deficiency of prior art being improved to solve prior art.
summary of the invention:
The object of the invention is to: a kind of ransaxle and carriage bolt fastening-connecting device are provided, and it can effectively save human resources.
The present invention adopts following technological scheme: a kind of ransaxle and carriage bolt fastening-connecting device, it comprises and is arranged at the corresponding mounting hole on described ransaxle and vehicle frame and is arranged in the square head bolt in described mounting hole, between mounting hole on described vehicle frame, be welded with chock, during described installation, vehicle frame aligns with the mounting hole on ransaxle, insert square head bolt, make the first side of its bolt and chock contacts side surfaces, ransaxle of the present invention and carriage bolt fastening-connecting device also include with described square head bolt locks friction tight self-locking nut.
Further, two square head bolts share a chock.
The present invention has following beneficial effect: the present invention adopts square head bolt, on vehicle frame, weld chock, during installation, bolt head contacts with chock, cannot rotation, and select self-locking nut, while the invention enables assembling, without two people, carry out, saved manpower, after installation, owing to having chock and self-locking nut, be all conducive to lockingly, eliminate easily loosening hidden danger.
accompanying drawing explanation:
Fig. 1 is ransaxle and carriage bolt fastening-connecting device schematic diagram in prior art.
Fig. 2 is ransaxle of the present invention and carriage bolt fastening-connecting device schematic diagram.
Wherein:
10-ransaxle; 20-vehicle frame; 30-square head bolt; 40-self-locking nut; 50-chock.
embodiment:
Please refer to shown in Fig. 2, between the mounting hole on vehicle frame of the present invention, be welded with chock 50 and then make to be installed on the shared chock 50 of two square head bolts 30 in mounting hole.On ransaxle 10, the position corresponding with mounting hole on vehicle frame 20 is provided with the same mounting hole that penetrates installation for square head bolt 30.When the present invention installs, vehicle frame 20 is alignd with the mounting hole on ransaxle 10, insert square head bolt 30, make the first side of its bolt and chock 50 contacts side surfaces, use after self-locking nut 40 pretensions, and then only need a people just can complete air inflating machine for dismantling tyre clamping bolt.
The present invention adopts square head bolt 30, welds chock 50 on vehicle frame 20, and during installation, bolt head contacts with chock, cannot rotation, and select self-locking nut.The invention enables assembling time without two people, to carry out, saved manpower, after installation, owing to having chock and self-locking nut, be all conducive to lockingly, eliminate easily loosening hidden danger.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make under the premise without departing from the principles of the invention some improvement, and these improve and also should be considered as protection scope of the present invention.
