Double swing arm disconnected front axle

Abstract

The invention relates to a double-swing-arm breaking type front axle which comprises a knuckle, a brake, a steering lever system, a supporting beam connected with the steering lever system, upper swing arms and lower swing arms, wherein the upper swing arms and the lower swing arms are connected with the supporting beam. One end of each upper swing arm and one end of each lower swing arm are on the same side and connected with the upper end and the lower end of the supporting beam in a pivoting mode, and the other ends on the same side are connected with a vehicle body. Two sets of upper swing arms and lower swing arms are arranged symmetrically in the bilateral direction. In the horizontal direction, a left lower swing arm and a right lower swing arm are opposite and in a shape of a character 'ba'. The steering lever system is arranged on one side of a large opening of the shape of the character 'ba' formed by the left lower swing arm and the right lower swing arm and is not higher than the lower swing arms. The space of the position of the large opening of the shape of the character 'ba' is suitable for horizontal swinging of the steering lever system, and steering lever system does not interfere with the left lower swing arm and the right lower swing arm. By arranging the lower swing arm and by means of the position relation of the lower swing arm and the steering lever system, the height of a vehicle floor is reduced, and passengers can get on and get off the vehicle conveniently.

Description

technical field [0001] The invention relates to a vehicle front axle device, in particular to a double swing arm disconnected front axle. Background technique [0002] The axle is used to transmit the force and moment in all directions between the frame and the wheel. According to the different suspension structure, it can be divided into two types: integral type and disconnected type. The non-independent suspension is matched with the integral type axle. The front axle of the traditional bus mostly adopts the I-beam bridge, and the I-beam front axle has high strength, but there is a problem that when the wheels at both ends impact each other, the mutual influence is large, which reduces the comfort performance of the vehicle and the stability of the vehicle driving; The independent suspension is combined with the disconnected axle. This design can make the wheels on both sides move independently without being affected. The space for wheel movement is large, the center of gr...
