Abstract
The utility model discloses a bus frame which is composed of a left longitudinal beam and a right longitudinal beam (1,2), a crossbeam (3) and a rear shock absorption supporting axle (4); wherein, the left and the right longitudinal beams (1,2) are arranged in parallel way, the crossbeam (3) is positioned between the left and the right longitudinal beams (1,2), the shock absorption supporting axle (4) is positioned at the corresponding location of the inner side at the rear part of the left and the right longitudinal beams (1,2), the center line of the shock absorption supporting axle (4) is vertical to the inner side surface of the longitudinal beams. The utility model is characterized in that the shock absorption supporting axle is changed to be vertical to the longitudinal beams from the original position which is parallel to the longitudinal beams; In this way, the center line of the shock absorption supporting axle will be vertical to the back-and-forth motion course of the shock absorption supporting axle, which guarantees the top lug can move freely around its center of circle when the shock absorber moves back and forth, thus breakage at the welding point of the top lug of the shock absorber can be prevented, and the service life of the shock absorber can be considerably prolonged. At the same time, the upper support beam of the shock absorption which is between the rear parts of the two longitudinal beams is removed, so as to make the bus lighter and saves the manufacturing cost.
Description
Technical field
The utility model relates to a kind of passenger vehicle, especially bus frame.
Background technology
At present, the general-duty bus frame is made up of two left and right longerons that be arranged in parallel 1,2 and some crossbeams 3 as shown in Figure 1, and crossbeam 3 is distributed between two longerons from front to back.Damping upper support beam 7 after the rear portion between two longerons is provided with one, welding back damping upper support axle 4 on the back damping upper support beam 7, the axial line of back damping upper support axle 4 is parallel with longeron, and the upper end of passenger vehicle rear shock absorber 8 is installed on this upper support axle, and the lower end is welded on the back axle bridge tube.The vehicle frame of this structure, cause rear shock absorber 8 lower ends when seesawing with back axle, the upper end suspension ring can not rotate with the center of circle, the axial line of upper support axle is consistent with the course bearing that seesaws of rear shock absorber, cause rear shock absorber suspension ring weld to rupture easily, reduce the service life of rear shock absorber.Damping upper support beam after being provided with one on the vehicle frame, the weight of vehicle frame increases the weight of, the corresponding increase of cost of manufacture more.Simultaneously, this fixed form of rear shock absorber has limited the type selecting of bumper, and promptly this vehicle frame is not general for the bumper of different model.
The utility model content
For solving above technical matters, the purpose of this utility model is to provide a kind of rear shock absorber suspension ring weld that can prevent to rupture, and effectively prolongs the rear shock absorber bus frame in service life.
The technical solution of the utility model is as follows: a kind of bus frame, comprise left and right longeron, crossbeam and back shock-absorption support axle, wherein left and right longeron be arranged in parallel, crossbeam is between left and right longeron, its key is: described back shock-absorption support axle is fixed on the relative position of left and right longeron posterior medial face, and the axial line of this back shock-absorption support axle is vertical mutually with the medial surface of described longeron.
The utility model is incited somebody to action back shock-absorption support axle by original change perpendicular to longeron parallel with longeron, the course bearing that seesaws of the axial line of back shock-absorption support axle and rear shock absorber is mutually 90 degree like this, when having guaranteed the rear shock absorber swing, the upper lift ring place can rotate with the center of circle, prevented that effectively rear shock absorber suspension ring weld from rupturing, and prolonged the service life of rear shock absorber greatly.Simultaneously, between two longeron rear portions, remove back damping upper support beam, made the weight saving of whole vehicle frame, and saved productive costs.
Above-mentioned back shock-absorption support axle is captiveed joint with the medial surface of longeron by bearing, and bearing is similar to " several " shape, its open end and the riveted joint of longeron medial surface; Be provided with a connecting panel in bearing, the inner of described back shock-absorption support axle is passed the knock hole on bearing closed end and the connecting panel successively, the hole wall welding of its axle body and knock hole.
The utility model can correspondingly be sought the installation site at the longeron medial surface according to the difference of rear shock absorber model, size, and by the fixing back of bearing shock-absorption support axle, compared with prior art, applicable surface is wider again.
Beneficial effect: the utility model can guarantee that the axial line of back shock-absorption support axle and the course bearing that seesaws of rear shock absorber are mutually 90 degree, effectively prolonged the service life of rear shock absorber, it have simple in structure, cost is low, advantage such as widely applicable, be suitable for large-scale promotion and use.
Description of drawings
Fig. 1 is this prior art constructions scheme drawing.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the scheme of installation of back of the present utility model shock-absorption support axle.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 2, shown in Figure 3, the utility model is made up of parts such as left longeron 1, right vertical beam 2, crossbeam 3, back shock-absorption support axle 4 and bearings 5, wherein left and right longeron 1,2 be arranged in parallel, crossbeam 3 is distributed between the left and right longeron 1,2 from front to back, and the two ends of crossbeam 3 difference riveted and fixed is on left and right longeron 1,2.Bearing 5 approximate " several " shapes, its open end and the riveted joint of longeron medial surface; In bearing 5, be provided with a connecting panel 6, the inner of described back shock-absorption support axle 4 is passed the knock hole on bearing 5 closed ends and the connecting panel 6 successively, the hole wall welding of its axle body and knock hole, and the axial line of back shock-absorption support axle 4 is vertical mutually with the medial surface of described longeron.
Claims (2)
1, a kind of bus frame, comprise left and right longeron (1,2), crossbeam (3) and back shock-absorption support axle (4), wherein left and right longeron (1,2) be arranged in parallel, crossbeam (3) is positioned between the left and right longeron (1,2), it is characterized in that: described back shock-absorption support axle (4) is fixed on the relative position of left and right longeron (1,2) posterior medial face, and the axial line of this back shock-absorption support axle (4) is vertical mutually with the medial surface of described longeron.
2, bus frame according to claim 1 is characterized in that: described back shock-absorption support axle (4) is captiveed joint with the medial surface of longeron by bearing (5), and bearing (5) is similar to " several " shape, its open end and the riveted joint of longeron medial surface; Be provided with a connecting panel (6) in bearing (5), the inner of described back shock-absorption support axle (4) is passed the knock hole on bearing (5) closed end and the connecting panel (6) successively, the hole wall welding of its axle body and knock hole.
