Background technology
The full air suspension of passenger-carrying chassis is made up of front air suspension and back air suspension.At present, front air suspension mainly is made up of lower bracket, air bellow, air bellow upper bracket, air bellow base, lateral rod and horizontal thrust shaft bar etc. on lower bracket, stabilizer rod, stabilizer bar arm, stabilizer rod suspension rod, stabilizer rod boom support, height-control valve, shock absorber, the shock absorber on guide arm, the guide arm.Back air suspension mainly is made up of lower bracket on up and down longitudinal rod, longitudinal thrust shaft bar, lateral rod, horizontal thrust shaft bar, air bellow, air bellow upper bracket, air bellow base, trailing arm beam, stabilizer rod, stabilizer bar arm, stabilizer rod suspension rod, stabilizer rod boom support, height-control valve, shock absorber and the shock absorber etc.In the full air suspension design plan of this type, guide arm can only play the guiding role, and horizontal thrust shaft bar, damper bracket design separately; The horizontal thrust pole length is fixed, and commonality is not strong, and inconvenience is installed; The trailing arm beam is welding part, foundry goods or forging, complex process, complex structure, productive costs height; Damper bracket, stabilizer bar arm are arranged apart, and number of parts increases.The increase of number of parts just means that the layout of the increase of tooling cost, the reduction of reliability (the assembly reliability is the product of each parts reliability) and part also is subjected to the influence of locus.There is complex structure in therefore existing type air suspension, part is various and because various reliability decrease, productive costs height, the installation complicated problems brought of part.
Summary of the invention
The purpose of this utility model is that the guide arm on the passenger-carrying chassis front air suspension is improved, to reach function that increases guide arm and the purpose of reducing the number of part, simplification technology, cost-cutting.
To achieve these goals, the utility model proposes a kind of passenger-carrying chassis front air suspension, be two air bag double damper structures, comprise steel spring guide arm and lateral rod, it is characterized in that: described guide arm is 1/2nd spring steel plate springs, guide arm wraparound ear end is pressed into resilient bushing and is connected with the vehicle frame upper bracket, and first of the other end is the supporting-point of lateral rod, and second rolls and become damper bracket.
To further improvement of above-mentioned passenger-carrying chassis front air suspension be: described front air suspension lateral rod is adjustable, and the lateral rod two ends are helicitic texture, and an end connects to ground, and the other end is connected with guide arm.
At above-mentioned purpose, the utility model also proposes a kind of back air suspension that is used with front air suspension, it is four gasbags four bumper structures, comprise air bellow, bumper and Panhard rod, they all have corresponding stressed supporting bracket, it is characterized in that: the lower support frame of air bellow is a kind of air bag trailing arm beam, described air bag trailing arm beam vertically superposes with two leaf spring materials, use bolt one trailing arm boom support therebetween, bumper and Panhard rod are connected on the described trailing arm boom support.
To further improvement of air suspension behind the above-mentioned passenger-carrying chassis be: described longitudinal rod upper bracket integral body is triangular form, and owner's body structure is welded for the trench structure bending part.
Can also further improve air suspension behind the passenger-carrying chassis in addition and be: described Panhard rod is connected on the described trailing arm boom support, and connects to ground by stabilizer rod suspension rod and stabilizer rod upper bracket; The Panhard rod two end portions is the arcuate shape that can avoid trailing arm beam and wheel interference.
The beneficial effects of the utility model:
The front air suspension guide arm is that 1/2nd straight leaf springs are the elastic guide arm of material, and its wraparound ear end is pressed into resilient bushing and is connected with the vehicle frame upper bracket, and first of the other end is the supporting-point of lateral rod, and second rolls into damper bracket.The use of resilient bushing, alleviated braking or when quickening to the rigid impact between the guide arm support.Though therefore this guide arm is simple for structure, but brought into play multiple function, not only transmission power and moment between vehicle frame and vehicle bridge, vehicle bridge is beated by relative vehicle body of certain track or vehicle frame, return lateral rod, shock absorber provides supporting-point, when having alleviated braking or acceleration, the use of resilient bushing, reduced noise to the rigid impact between guide arm and the support thereof.
Lateral rod is that screw thread is adjustable, can be by the length of threaded adjusting lateral rod, owing to adjustable length, easy for installation, highly versatile.The layout actv. of lateral rod has transmitted side force, and the horizontal thrust shaft bar extends as much as possible downwards, has reduced the suspension roll center of moment.
