Abstract
The invention relates to a rear suspension system of a vehicle, in particular to a leaf-spring type rear suspension system of a low-floor urban bus. The system comprises a rear leaf spring, a rear transverse stabilizing rod and a rear shock absorber, and is characterized in that: the rear leaf spring is arranged below a rear axle pipe; the rear transverse stabilizing rod is arranged below the rear leaf spring; and the rear shock absorber is arranged on the outer side of a frame and above the rear leaf spring. Through the rear suspension provided by the invention, the gravity center of the whole vehicle can be lowered, and the stability of the whole vehicle is improved; the mounting bracket of the rear transverse stabilizing rod and the rear shock absorber is simplified, the frame system at the rear axle is simplified, the frame weight is reduced, and the cost of the whole vehicle is lowered; and a retarder can be conveniently added to the rear axle.
Description
Technical field
The present invention relates to a kind of rear-suspension system of vehicle, particularly a kind of leaf spring type rear-suspension system that is applied to the low floor city bus.
Background technology
When the city bus floor level drops to 600mm by 900mm; Floor level has descended 33%; The time of getting on and off can be saved more than 50%, and therefore, (floor level 600mm-550mm) the large, medium and small at home city of city bus all has vast market prospect to low floor.
There is following shortcoming in the rear-suspension system of existing vehicle: the back leaf spring is arranged on the bridge tube of back, and chassis frame height can't reduce; Rear shock absorber is arranged in the vehicle frame inboard, influences to install retarder on the back axle additional; Back Panhard rod is arranged on the leaf spring, influences the system design and the simplification of vehicle frame.
Summary of the invention
The object of the invention: provide a kind of leaf spring type rear-suspension system of low floor city bus, it can reduce chassis frame height, does not influence and installs retarder on the back axle additional; Simultaneously, reduce the car load center of gravity, improved whole vehicle stability; Simplify the mounting bracket of back Panhard rod and rear shock absorber, simplified back axle place frame system and frame, reduced vehicle frame weight, reduced integral vehicle cost; Made things convenient for back axle to install retarder additional.
Technical scheme of the present invention: the leaf spring type rear-suspension system that designs a kind of low floor city bus; Comprise the layout of back leaf spring, the layout of back Panhard rod, the layout of rear shock absorber; It is characterized in that: the back leaf spring that is arranged as of leaf spring is arranged under the bridge tube of back after described, and the after poppet of the front frame of back leaf spring and back leaf spring passes through bolted connection on vehicle frame; The back Panhard rod that is arranged as of described back Panhard rod is arranged under the leaf spring of back; Back Panhard rod one end is connected on the vehicle frame through back Panhard rod front frame, and the back Panhard rod other end is fixedly connected on the Panhard rod after poppet of back through bolt pin; The rear shock absorber that is arranged as of rear shock absorber is arranged in the vehicle frame outside, and on the back leaf spring, the lower bracket of rear shock absorber is welded on the bridge tube of back, and the upper bracket of rear shock absorber is welded on the vehicle frame.
The invention has the beneficial effects as follows: adopt rear-suspension system of the present invention through the back leaf spring is arranged under the bridge tube of back, rear shock absorber is arranged in the vehicle frame outside, and back Panhard rod is arranged under the leaf spring of back; Thereby reduced the car load center of gravity, improved whole vehicle stability; Simplify the mounting bracket of back Panhard rod and rear shock absorber, simplified back axle place frame system and frame, reduced vehicle frame weight, reduced integral vehicle cost; Made things convenient for back axle to install retarder additional.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the present invention is described further, but not as to qualification of the present invention.
Fig. 1 is the leaf spring type rear-suspension system scheme drawing of the low floor city bus of the embodiment of the invention;
Fig. 2 is the birds-eye view of Fig. 1.
Among the figure: 1, front frame; 2, back Panhard rod front frame; 3, back Panhard rod; 4, back leaf spring; 5, lower bracket; 6, back Panhard rod after poppet; 7, rear shock absorber; 8, upper bracket; 9, after poppet; 10, bolt; 11, back bridge tube; 12, bolt pin; 13, vehicle frame.
Specific embodiment
The system that is not described in detail in an embodiment, its system is identical with existing known system.
As depicted in figs. 1 and 2; The leaf spring type rear-suspension system of low floor city bus; Comprise the layout of back leaf spring, the layout of back Panhard rod, the layout of rear shock absorber; It is characterized in that: the back leaf spring 4 that is arranged as of described back leaf spring is arranged under the bridge tube 11 of back, and the front frame 1 of back leaf spring 4 is connected on the vehicle frame 13 through bolt 10 with the after poppet 9 of back leaf spring 4; The back Panhard rod 3 that is arranged as of described back Panhard rod is arranged under the leaf spring 4 of back; Back Panhard rod 3 one ends are connected on the vehicle frame 13 through back Panhard rod front frame 2, and back Panhard rod 3 other ends are fixedly connected on the back Panhard rod after poppet 6 through bolt pin 12; The rear shock absorber 7 that is arranged as of rear shock absorber is arranged in vehicle frame 13 outsides, and on the back leaf spring 4, the lower bracket 5 of rear shock absorber 7 is welded on the bridge tube 11 of back, and the upper bracket 8 of rear shock absorber 7 is welded on the vehicle frame 13.
Rear-suspension system of the present invention is that rear shock absorber 7 is arranged in vehicle frame 13 outsides through under the bridge tube 11 after back leaf spring 4 is arranged in, and back Panhard rod 3 is arranged under the leaf spring 4 of back; Thereby reduced the car load center of gravity, improved whole vehicle stability; Simplify the mounting bracket of back Panhard rod and rear shock absorber, simplified back axle place frame system and frame, reduced vehicle frame weight, reduced integral vehicle cost; Made things convenient for back axle to install retarder additional.
