Abstract

The utility model relates to a passenger car chassis rear suspension frame, which is characterized in that the entire frame adopts a grid structure which is formed by pieces through welding, a sheet welding assembly is formed by longitudinal beams and stand columns, shock absorber seats are welded on transverse beams, airbag seats are welded on the transverse beams on the back surfaces of the shock absorber seats, grooved steel plate structures are adopted at the positions of airbag seats and diagonal bracings are welded between the transverse beams and the longitudinal beams on the bottom surface. Compared with the background technology, the passenger car chassis rear suspension frame has the advantages that the structural strength can be improved by adopting the novel structure, the weight of the entire car can be reduced, the cost is low, the labor productivity is improved and the entire passenger car can run safely and is comfortable and reliable.

Description

Passenger-carrying chassis rear overhang skeleton

Technical field

The utility model relates to a kind of passenger-carrying chassis vehicle frame, especially relates to a kind of design of passenger-carrying chassis rear suspension.

Background technology

Along with the fast development of highway bus, passenger-carrying chassis skeleton occupies very important status in passenger-carrying chassis structure, and especially outstanding behaviours is in the design of automobile chassis rear suspension.The new process of employing new technology is manufactured chassis becomes the target of each automobile manufacturing enterprise products innovation, rear suspension affects safety, traveling comfort and the reliability of whole passenger vehicle, adopts new structure can increase structural strength, alleviates the weight of car load, reduce costs, raise labour productivity.

At present, passenger vehicle enterprise adopts edge-beam type structure, and intensity is low, and processing needs large-sized processing equipment, and equipment manufacturing cost is very high, and wagon processing factory does not have equipment purchase ability, is all to adopt outer processing, and cost is very high, has improved the manufacturing cost of car load.

Utility model content

The purpose of this utility model is to provide that a kind of intensity is high, the passenger-carrying chassis rear overhang skeleton of low cost of manufacture.

For achieving the above object, the utility model provides a kind of passenger-carrying chassis rear overhang skeleton, it is characterized in that: whole vehicle frame adopts lattice bar structure burst to be welded, form sheet welding assembly by longeron and column, on crossbeam, be welded with shock absorber bearing, on the crossbeam at the shock absorber bearing back side, be welded with gasbag seat, adopt U-steel plate structure at gasbag seat place, between the crossbeam of bottom surface and longeron, be welded with diagonal brace.

The advantage that the utility model is compared background technology generation is: adopt new structure can increase structural strength, alleviate the weight of car load, reduce costs, raise labour productivity, whole passenger vehicle safe in operation, comfortable and reliable.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the back view of Fig. 1.

The specific embodiment

With reference to Fig. 1, Fig. 2, the utility model comprises crossbeam, longeron 2, shock absorber bearing 3, column 4, bottom cross beam 5, diagonal brace 6, gasbag seat 7, whole vehicle frame adopts lattice bar structure burst to be welded, on crossbeam, be welded with shock absorber bearing, on the crossbeam at the shock absorber bearing back side, be welded with gasbag seat, adopt U-steel plate structure at gasbag seat place, between the crossbeam of bottom surface and longeron, be welded with diagonal brace.Shock absorber bearing adopts plug welding mode to prevent that stress from producing.Whole assembly has welded, and polishing is removed slag, at the bottom of after the rust cleaning of deoiling, twice anti-rust paint of spraying sprays chassis after dry.

Claims (1)

1. a passenger-carrying chassis rear overhang skeleton, it is characterized in that: whole vehicle frame adopts lattice bar structure burst to be welded, form sheet welding assembly by longeron and column, on crossbeam, be welded with shock absorber bearing, on the crossbeam at the shock absorber bearing back side, be welded with gasbag seat, adopt U-steel plate structure at gasbag seat place, between the crossbeam of bottom surface and longeron, be welded with diagonal brace.
