Problems solved by technology

[0002] At present, the commercial vehicle frame assembly structure is to use rivets to connect U-shaped beam assembly, back-to-back tail beam assembly, engine front bracket, engine rear bracket, back-to-back beam assembly, front leaf spring fixed support, front suspension Lug leaf spring support, rear leaf spring fixed support, rear leaf spring lug support and the frame longitudinal beam are connected and fixed, and the design structure of the frame assembly, but due to the actual working conditions and the complex force of the frame, The problem of cracking and breaking of the beam assembly and the hanger, as well as the loosening or breaking of the connecting bolts, the torsion resistance of the frame is weak, the vehicle shakes seriously, the structural design of the frame assembly is unreasonable, and some beam structures are redundant. The problem of heavy weight and low versatility of the frame beam seriously affects the performance of the vehicle and brings great safety hazards

Embodiment 1

[0054] A frame assembly structure with a short wheelbase and variable width, comprising a first longitudinal beam 3, a second longitudinal beam 4, a tubular beam assembly 1, an arc beam assembly 9, a rear-front back-to-back beam assembly 17, a rear Back-to-back beam assembly 18, tail beam assembly 19;

[0055] The axis of the first longitudinal beam 3 is arranged parallel to the axis of the second longitudinal beam 4 , and the first end of the first longitudinal beam 3 and the first end of the second longitudinal beam 4 pass through The tubular beam assembly 1 is fixedly connected, with the first end of the first longitudinal beam 3 and the first end of the second longitudinal beam 4 as the front end of the frame assembly;

[0056] The tubular beam assembly 1 includes a tubular beam body and two connecting sleeves fixedly connected at both ends thereof, the two ends of the tubular beam body are respectively inserted into one ends of the two connecting sleeves, and the other en...

Embodiment 2

[0062] Compared with the solution of Embodiment 1, the short-wheelbase variable-width vehicle frame assembly structure also includes a spare tire support assembly 15, and the two ends of the spare tire support assembly 15 are respectively connected to the rear backrest beam assembly. 18 and the tail beam assembly 19 are fixedly connected.

[0063] It should be noted that the spare tire support assembly 15 mainly ensures the rationality of the installation position of the spare tire and the reliability and firmness of the installation; the tail beam assembly 19 ensures the installation of the spare tire support.

Embodiment 3

[0065] Compared with the solutions of Embodiments 1 and 2, the frame assembly structure with short wheelbase and variable width also includes two front leaf spring fixing supports 5 and two front lifting lug leaf spring supports 7, and the two front plates The spring fixing support 5 and the two front lug leaf spring supports 7 are symmetrically fixed on the first longitudinal beam 3 and the second longitudinal beam 4 respectively, and the front leaf spring fixing support 5 is located on the front lifting lug plate In front of the spring support 7 , the front leaf spring fixed support 5 and the front lug leaf spring support 7 are located between the tubular beam assembly 1 and the arc beam assembly 9 .

[0066] It should be noted that the front leaf spring fixing support 5 and the front lug leaf spring support 7 are mainly to ensure the reliability and safety of the connection between the vehicle frame assembly and the front suspension system.

Abstract

The invention provides a short wheelbase variable width frame assembly structure. The short wheelbase variable width frame assembly structure is composed of a tubular beam assembly, an upper and lowerpiece beam assembly, an arc-shaped beam assembly, a rear-front backrest type beam assembly, a rear-rear backrest type beam assembly, a tail part beam assembly, an angle iron type beam, two-axis limiting bracket assemblies, a transmission shaft hanging bracket assembly, rear axle frame reinforcement brackets, engine front brackets, engine rear brackets, front leaf spring fixed bearings, front lifting lug leaf spring supports, rear leaf spring fixed bearings, rear leaf spring lifting lug supports, auxiliary leaf spring supports, a spare tire bracket assembly and the like. According to the shortwheelbase variable width frame assembly structure, the overall bending resistance and the torsion resistance of a vehicle frame assembly can be improved, the weight and cost of the frame assembly arereduced, the cracking of a frame beam assembly is eliminated, shaking of an engine is reduced, the universality of the frame beam assembly is improved, the development cycle of the frame assembly andthe frame beam assembly is reduced, the layout space of a vehicle is improved, and the frame assembly width requirement is improved.
