[0008] It is further defined that, in the above technical solution, fixing holes are provided at both ends of the nylon frame, which can facilitate the fixed installation of the integral front suspension limit block body on the vehicle frame.

[0009] It is further defined that, in the above technical solution, the front suspension limit block body is fixed to the upper end surface of the frame by fastening screws passing through the fixing holes.

[0010] It is further defined that in the above technical solution, support frames are provided on both sides of the frame, the cross section of the support frame is a groove-shaped structure, and the front suspension limit block body is fixedly installed on the upper end surface of the groove-shaped structure.

[0011] The beneficial effects of the present invention are as follows: the present invention proposes a new commercial vehicle cab with a front suspension limit block structure, which adopts a nylon + rubber pad structure, has a simple structure, light weight, low cost, high production efficiency and high precision, and solves the problems of the front suspension limit block structure being relatively complex and heavy in weight in the prior art. The overall structural layout is reasonable and has stronger versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In the present application, the front suspension limit block body 5 is fixed to the vehicle frame by passing fastening screws through both ends of the nylon frame 6; an anti-collision protrusion 10 is also provided on the stabilizer bar 3 at a position opposite to the front suspension limit block body 5, which can provide good protection for the stabilizer bar 3.

[0020] See Figure 1-4 What is shown is a new commercial vehicle cab with a front suspension limit block structure, which includes a frame 1, a cab 2 installed on the upper part of the frame 1, a stabilizer bar 3 horizontally arranged at the lower end of one side of the cab 2, shock-absorbing springs 4 are arranged at both ends of the stabilizer bar 3, and a front suspension limit block body 5 is arranged at one side of the shock-absorbing spring 4 facing the upper end of the frame 1. The front suspension limit block body 5 includes a nylon frame 6, and a rubber pad 7 is arranged at the upper end of the nylon frame 6.

[0021] The area of ​​the rubber pad 7 is smaller than that of the nylon frame 6. The nylon frame 6 and the rubber pad 7 are vulcanized together. Fixing holes 8 are provided at both ends of the nylon frame 6. The front suspension limit block body 5 is secured to the upper end face of the vehicle frame 1 via fastening screws inserted through the fixing holes 8. Support frames 9 are provided on both sides of the vehicle frame 1. The support frames 9 have a trough-shaped cross-section, and the front suspension limit block body 5 is fixedly mounted to the upper end face of the trough-shaped structure.

[0022] The working principle of the new commercial vehicle cab with front suspension limit block structure is as follows:

[0023] During actual use, the cab 2 will jump up and down at one end due to vibration. During the downward jumping process of the cab 2, the stabilizer bar 3 will move downward. The downward movement of the stabilizer bar 3 will touch the rubber pad 7 at the upper end of the front suspension limit block body 5 to cushion the shock and prevent collision. This can effectively prevent the cab 2 from continuing to move downward, thereby achieving a good protective effect.

[0024] The front suspension limit block structure in this application has the following advantages over the traditional structure: it is more convenient to install and operate, light weight and low cost, high production efficiency and high precision, and a shorter development cycle. It has advantages in product development cycle as well as cost, weight, precision, etc.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
