Further, the first plate (1) can be fixed with the bottom end of the front axle framework (6).

Furthermore, the first plate (3) and the two fishplates (1-1) are integrally formed, and the two fishplates (1-1) are respectively connected with the beams at the two ends of the front axle framework.

Further, the two side plates (3) are respectively welded with the first plate (1) and the second plate (2).

Furthermore, the number of the slopes of the recess (3-1) is more than or equal to 3.

Further, the two side plates (3) are perpendicular to the second plate (2), respectively.

Furthermore, the first plate (1) is a steel plate, the two side plates (3) are both steel plates, and the second plate (2) is a steel plate.

Furthermore, the rear part of the recess (5) is provided with a through hole (3-2).

The utility model has the advantages that:

1. the requirement on the first-stage stepping low floor of the front axle frame can be met by installing the lower swing arm fixing seat at the lower end of the front axle frame; the steering pull rod system can be effectively arranged through a plurality of sunken slopes, and movement interference is avoided.

2. The left and right side swing arm installation accuracy of independent front axle can be improved through the hole that link up, only need during the assembly pass swing arm fixing base down with stud and tighten with certain moment, when satisfying the increase structural strength, also can cushion the vibration of going.

Detailed Description

The technical solution of the present invention will be further described and explained below with reference to the accompanying drawings and the embodiments, but the present invention is not limited to the following embodiments.

A lower swing arm fixing seat of a low-floor passenger car is characterized in that a sandwich body is formed by clamping and supporting blocks (4) in the middle of a left side plate and a right side plate (3), a first plate (1) is arranged at the top of the sandwich body, fishplates (1-1) are respectively arranged at the front end and the rear end of the first plate (1) in an extending mode, the two side plates (3) are respectively perpendicular to the first plate (1), two windows (3-1) which are communicated left and right and a recess (5) are sequentially arranged from the front end to the rear end of the sandwich body, a second plate (2) is arranged at the bottom of each window (3-1), a through hole (3-2) is respectively arranged in the front of each window (3-1), the height of each recess (5) is larger than that of each window (3-1), and the lower swing arm can swing in each recess (5). The two side plates (3) are respectively perpendicular to the second plate (2). The first plate (1) is a steel plate, the two side plates (3) are both steel plates, and the second plate (2) is a steel plate. The rear part of the recess (5) is provided with a through hole (3-2). The two side plates (3) are respectively welded with the first plate (1) and the second plate (2). The recess (3-1) contains 3 transition slopes and one horizontal slope.

The working process is as follows:

the first plate (1) can be fixed with the bottom end of the front axle framework. The first plate (3) and the two fishplates (1-1) are integrally formed, and the two fishplates (1-1) are respectively welded with beams at two ends of the front axle framework (6).
