Detailed ways

As shown in Figure 1: the front suspension device of the truck cab of the utility model includes a turning support 1, a turning arm assembly 2 hinged on the turning support 1, and a front suspension upper bracket assembly hinged with the turning arm assembly 2 3. The spring damper 4 connected between the flip arm assembly 2 and the front suspension upper bracket assembly 3, the left and right flip arm assemblies 2 are connected by the stabilizer bar 5.

As shown in Fig. 2 and Fig. 3: the utility model includes a turning support 1, a turning arm assembly 2 hinged on the turning support 1, and a front suspension upper bracket assembly 3 hinged with the turning arm assembly 2, connected to The spring shock absorber 4 between the flip arm assembly 2 and the front suspension upper bracket assembly 3, and the left and right flip arm assemblies 2 are connected by a transverse stabilizer bar 5; Limiting plate 12, upper limit block 9 is set on the top of limit plate 12, upper limit block 9 is connected on the front suspension upper bracket assembly 3, lower limit block 10 is established at the bottom of limit plate 12, lower limit block 10 is also connected on the front suspension upper bracket assembly 3.

A limit bearing 11 is installed on the upper bracket assembly 3 of the front suspension, and the upper limit block 9 is connected to the limit support 11 through a limit rod 8 .

A U-shaped frame 13 is installed on the upper bracket assembly 3 of the front suspension, and the U-shaped frame 13 frames the left and right turning arm assemblies 2 therein, and the lower limit block 10 is fixed on the upper side of the base plate of the U-shaped frame 13 .

A protective cover plate 14 is installed on the side where the turning arm assembly 2 is connected with the turning support 1 and the spring shock absorber 4 to cover the lower ends of the turning support 1 and the spring damper 4 .

One end of the front suspension upper bracket assembly 3 is provided with a shaft hole 15 hinged with the flip-limiting link mechanism.
