Embodiment 1

[0072] see Figure 1 to Figure 9 , an assembly process of a vehicle frame connection assembly, comprising the following steps:

[0073] Steps for connecting longitudinal beam castings: first connect the front end of the left longitudinal beam 10 of the vehicle frame with one end of the left large casting bracket 20, and then connect the front end of the right longitudinal beam 1 of the vehicle frame with one end of the right large casting bracket 2, At this time, the right side beam 1 of the vehicle frame and the left side beam 10 of the vehicle frame are parallel to each other; the distance between the left side beam 10 of the vehicle frame and the right side beam 1 of the vehicle frame is the inner width of the vehicle frame 101; The part on the bracket 20 sandwiched between the left longitudinal beam 10 of the vehicle frame and the cross beam 255 of the vehicle frame is the left inner concave area 102, and the bracket 2 of the right large casting is clamped between the righ...

Embodiment 2

[0077] Basic content is the same as embodiment 1, the difference is:

[0078] Structurally: the casting machine is provided with an upper left casting pillar 211, a lower left casting pillar 212, an upper right casting pillar 213 and a lower right casting pillar 214 from the plate 23, and the upper left casting pillar 211, the lower left casting pillar 212, and the upper right casting pillar 213 1. The inside of the lower right casting pillar 214 is provided with a pillar connecting hole 215; the distance between the upper left casting pillar 211 and the upper right casting pillar 213, and the distance between the left lower casting pillar 212 and the right lower casting pillar 214 are all greater than the upper left casting pillar 214. The spacing of casting strut 211 , lower left casting strut 212 and the spacing of upper right casting strut 213 , lower right casting strut 214 .

[0079] In terms of technology: in the assembly step of the steering gear: the casting machine i...

Embodiment 3

[0081] Basic content is the same as embodiment 2, the difference is:

[0082] Structurally: the steering frame bracket 4 includes a frame frame body 41 and an output shaft hole 42 opened thereon, a frame connection hole 43, and a frame connection hole 44, and the frame connection hole 44 includes a left upper frame hole 441 , the left lower frame hole 442, the right upper frame hole 443 and the right lower frame hole 444; the distance between the left upper frame hole 441 and the right upper frame hole 443 is the upper hole distance 445, the left lower frame hole 442, The distance between the lower frame holes 444 is the lower hole distance 446, the distance between the left upper frame hole 441 and the left lower frame hole 442 is the left hole distance 447, the right upper frame hole 443, and the right lower frame hole 444 The distance between the holes is the right hole distance 448, and the upper hole distance 445 and the lower hole distance 446 are greater than the left h...

Abstract

The invention discloses an assembly process of a vehicle frame connecting assembly. The front end part of a left longitudinal beam of a vehicle frame is connected with one end of a left large castingbracket firstly, then the front end part of a right longitudinal beam of the vehicle frame is connected with one end of a right large casting bracket, and the other end of the left large casting bracket and the other end of the right large casting bracket are correspondingly connected with the two ends of the vehicle frame cross beam to form a U-shaped structure; and a steering gear is connected with a steering gear bracket, a steering pitman arm is connected with a steering gear output shaft on the steering gear, then the steering gear bracket is connected with the middle part of the right large casting bracket, the right large casting bracket is located between the right longitudinal beam of the vehicle frame and the steering gear bracket after the connection, and at the moment, the assembly process is finished. The assembly process of the vehicle frame connecting assembly not only is high in integration degree but also high in assembly efficiency.

Description

technical field [0001] The invention relates to an assembly process of auxiliary parts on a vehicle frame longitudinal beam, belongs to the field of vehicle assembly, and in particular relates to an assembly process of a vehicle frame connection assembly. Background technique [0002] The vehicle steering device is an important accessory part of the frame longitudinal beam. It generally includes a steering gear. When assembling, the output end of the steering gear is connected to the steering drop arm, and the steering gear is connected to the frame longitudinal beam through the steering gear bracket. . [0003] However, most existing steering gear brackets adopt a separate design structure without considering the fusion design with other brackets, resulting in a relatively large volume and heavy weight of the entire steering system, which is very inconvenient to assemble. [0004] The application publication number is CN106428206A, and the application publication date is F...
