Problems solved by technology

[0002] The front section of the chassis frame of the existing low-driving area passenger car is generally a full-load structure. The frame process of the full-load structure is complicated, and the installation of the front suspension is complicated and difficult. The installation time is long, which increases the manufacturing cost of the car and causes unnecessary waste.
The three-section frame of the existing tourist bus is mostly of the ordinary driving area type, less in the low driving area, and even less in the low driving area and equipped with leaf spring suspension

Embodiment Construction

[0012] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0013] figure 1 Shown is the structural representation of the present invention.

[0014] The present invention consists of two parts, a lower main body part and an upper main body part.

[0015] The lower body part includes a first crossbeam assembly 1 , a first left longitudinal beam 2a, a first right longitudinal beam 2b and a second lower crossbeam assembly 3 through bolts and nuts.

[0016] The upper main body part includes the second upper beam assembly 4, the second left longitudinal beam 5a, the second right longitudinal beam 5b and the third beam assembly 6, which are connected by bolts.

[0017] The second left longitudinal beam 5a is a bent structure, the second right longitudinal beam 5b is structurally symmetrical with the second left longitudinal beam 5a, and the upper main body part composed of the second upper beam assembly 4 and ...

Abstract

The invention discloses a front-section assembly of a leaf spring suspension chassis frame of a low drive zone passenger car. The front-section assembly is composed of two parts including the lower main part and the upper main part. The lower main part is formed by connecting a first cross beam assembly, a first left longitudinal beam, a first right longitudinal beam and a second lower cross beam assembly through bolts and nuts. The upper main part is formed by connecting a second upper cross beam assembly, a second left longitudinal beam, a second right longitudinal beam and a third cross beam assembly through bolts. By the adoption of the front-section assembly, the longitudinal beams on the front section of the frame are formed by connecting upper sections with lower sections, and connecting positions are reinforced through an upper cross beam, a lower cross beam and side connecting boards. The second left longitudinal beam and the second right longitudinal beam on the front section of the frame are of bent structures. Longitudinal beam steel pipes on the middle section of the frame are arranged of the same-form structure. Steel pipe transition positions are welded. The bent portions of the second left longitudinal beam and the second right longitudinal beam on the front section of the frame are reinforced through additionally-arranged connecting boards. The first left longitudinal beam and the first right longitudinal beam on the front section of the frame are of the sectional structures with the rear portions higher than the front portions. The front-section assembly has the beneficial effects of being simple in structure, firm, stable, convenient to assemble, low in cost and high in universality.

Description

technical field [0001] The invention relates to a front section assembly of a leaf spring suspension chassis frame of a passenger car, which belongs to the technical field of auto parts. Background technique [0002] The front section of the chassis frame of the existing low-driving area passenger car is generally a full-load structure. The frame process of the full-load structure is complicated, and the installation of the front suspension is complicated and difficult. The installation time is long, which increases the manufacturing cost of the car and causes unnecessary waste. Most of the existing tourist bus three-section frames are of the common driving area type, less in the low driving area, and even fewer in the low driving area and equipped with leaf spring suspensions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a front section assembly of a leaf spring suspension chassis frame of a passenger car wit...
