Problems solved by technology

However, due to the elasticity of the airbag shock absorber and the characteristic that it can only bear vertical loads, the airbag shock absorber system will bear the weight of the entire cab when the front cab is turned over, which is easy to cause fatigue damage. At the same time, the front suspension system cannot avoid the lateral movement of the cab, which will cause low-frequency shaking and cause instability in the turning process

Embodiment 1

[0029] refer to Figure 1-Figure 4 As shown, the present embodiment is a cab front suspension structure, including a stabilizer bar assembly, a shock absorber assembly, an upper bracket assembly, a lower bracket assembly and a lifting mechanism, including a stabilizer bar 7, Shock absorber (air spring) 3, upper bracket 4, lower bracket 1 and lift cylinder 8; one end of upper bracket 4 is connected to the upper end of shock absorber 3, and the other end is rotatably connected to the lifting mechanism (lift cylinder); upper bracket 4 has Corresponding to the first position and the second position of the driving state and the overturning state respectively;

[0030] The lower bracket assembly also includes an overturning shaft 2 and an overturning guide rail 9. The overturning guide rail 9 is fixedly arranged on the upper part of the lower bracket assembly. The upper part of the overturning guide rail 9 is provided with an arc-shaped guide rail surface. The lower end of the shoc...

Embodiment 1-1

[0033] Based on Example 1, in this example, refer to figure 1 with figure 2 As shown, the shock absorber 3 in the shock absorber assembly adopts an air spring. The lower end of the shock absorber is fixedly connected with the turning shaft 2, and the middle part of the upper bracket assembly is connected with the turning shaft 2 through the stabilizer bar assembly. Since the turning shaft is fixedly arranged at both ends of the stabilizer bar, the lower end of the shock absorber 3 and the upper bracket assembly can also be connected to the stabilizer bar assembly.

[0034] The turning guide rail 9 is integrally formed with the lower bracket. The overturning roller 10 is fixedly connected to the upper bracket 4 through an integrally formed mounting plate, and the position where the overturning roller can contact the guide rail surface is an open ring with a wall thickness of 90mm, and the two ends of the opening are integrally connected with L-shaped reinforcing ribs.

Abstract

The invention discloses a cab front suspension structure and an automobile applying the cab front suspension structure. The front suspension structure comprises a transverse stabilizer bar assembly, ashock absorber assembly, an upper support assembly, a lower support assembly and a lifting mechanism. One end of the upper bracket is connected with the upper end of the shock absorber, and the otherend is connected with the lifting mechanism; the upper bracket has a first position and a second position which respectively correspond to a driving state and an overturning state; the lower supportassembly comprises an overturning shaft and an overturning guide rail, the overturning guide rail is fixedly arranged on the upper portion of the lower support assembly, an arc-shaped guide rail faceis arranged on the upper portion of the overturning guide rail, the overturning shaft is fixedly connected with the end of the transverse stabilizer bar, and the lower end of the shock absorber and the middle of the upper support assembly are connected with the overturning shaft or the transverse stabilizer bar. The lower portion of the upper support assembly is fixedly connected with an overturning roller, and the overturning roller is provided with a curved surface capable of moving along the guide rail face of the overturning guide rail in the process that the upper support assembly is switched from the first position to the second position. Guiding and gravity supporting in the overturning process can be achieved, and the stability of the cab in the overturning process is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles and engineering machinery, in particular to a cab front suspension structure and an automobile. Background technique [0002] The cab suspension system generally includes a shock absorbing structure, an anti-rolling structure, a locking structure, an overturning structure, a limiting structure and other connecting components. The main function of the cab suspension system: support, bear the weight of the cab assembly and the occupant, avoid large relative displacement and guide the vertical movement relative to the chassis, and at the same time ensure a stable connection with the frame; vibration isolation , with good vibration isolation performance, to attenuate uneven road surface and vibration and impact transmitted by suspension and frame during acceleration and braking, avoid low-frequency large shaking and have good vibration comfort; realize the turning of the cab, through The movement...
