Description
Technical field
The utility model belongs to the passenger vehicle technical field, specifically, relates in particular to the chassis of the rearmounted city bus of low inlet.
Background technology
Domestic existing rear-mounted passenger-carrying chassis generally is divided into two-stage stepping structure and the one-level two kinds of patterns of structure of marking time, and in order to improve quick exchange high capacity passenger, the city bus that has adopts the rearmounted chassis of low inlet, realizes that Qianmen and middle door one-level mark time.The traditional rearmounted city bus of low inlet chassis adopts air suspension to satisfy the one-level structural shape of marking time, because air suspension complex structure, manufacturing cost and maintenance cost are higher, have only the flourishing city of part economy can bear its high price at home, therefore be of limited application.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, manufacturing and the rearmounted city bus of low inlet chassis easy to maintenance.
The technical solution of the utility model is as follows: the rearmounted city bus of a kind of low inlet chassis, in the front portion of vehicle frame big drop gate-type propons is set, and the rear portion of vehicle frame is provided with drive axle, and its key is: described propons and drive axle all connect to ground by the leaf spring suspension.
Above-mentioned leaf spring suspension comprises leaf spring, U-bolt, steel plate pin, hanger, hanger pin and spring bracket, wherein the middle part of leaf spring is fixed on propons or the drive axle by U-bolt, the front end of leaf spring and first spring bracket are hinged, and first spring bracket is fixed on the longeron of vehicle frame; The rear end of described leaf spring is hinged by the lower end of hanger pin and hanger, and the upper end of hanger is hinged by the steel plate pin and second spring bracket, and described second spring bracket also is fixed on the chassis side rail.
Next door at above-mentioned leaf spring suspension is provided with shock absorber, and the lower end of this shock absorber is connected with propons or drive axle, and the upper end and the bearing of shock absorber are hinged, and described bearing is fixed on the longeron of vehicle frame.
The beneficial effects of the utility model are:
1, adopt the cooperation of leaf spring suspension and big drop gate-type propons, simple in structure, assembling can effectively reduce manufacturing cost and maintenance cost easily, helps applying on a large scale.
2, the car load center of gravity be can reduce, when improving quick exchange high capacity passenger purpose, car load travelling comfort, traveling comfort and stability further improved.
