Integrated passenger car driving shaft framework with adjustable width

Abstract

The width-adjustable integrated passenger car driving shaft framework comprises a framework body, the framework body is provided with a middle framework, a left wheel cover framework and a right wheel cover framework, and the left wheel cover framework and the right wheel cover framework are symmetrically arranged on the two sides of the middle framework, so that an in-car passageway is formed above the middle framework; the middle framework comprises a left framework, a right framework and a connecting assembly; the left framework and the left wheel cover framework are integrally cast, and the right framework and the right wheel cover framework are integrally cast; the left framework and the right framework are connected through a connecting assembly, and width adjustment of an aisle in a vehicle is achieved. The driving shaft framework of the passenger car is formed by splicing the left framework and the right framework which are integrally cast and formed, high integration can be achieved, the width of an aisle in the car can be adjusted, the width requirements of different car types can be met, and the driving shaft framework of the passenger car is convenient to use. The automatic assembling machine has the advantages of high assembling efficiency, high positioning precision, good universality, low failure rate, high structural strength and the like.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an adjustable width-adjustable integrated drive shaft frame for passenger cars. Background technique [0002] At present, in the industry, the bus frame based on the independent suspension wheel drive system is a steel pipe welded structure. This structure is extremely dependent on the skills of the welder and the accuracy of the welding fixture, and the welding process is also difficult to control. If there is a slight deviation, it will be easy. It will lead to four-wheel alignment deviation, and problems such as insufficient welding strength. In addition, the steel pipe welded structure also has disadvantages such as low production efficiency, high labor cost, poor applicability, and poor lightweight level. Contents of the invention [0003] The invention provides an adjustable width-adjustable integrated driving shaft frame of a passenger car, and its main purpose is to s...
