Abstract
The utility model relates to a semi-trailer, namely an air bag suspension structure for a triaxial semi-trailer. An upper seat and a bearing bracket seat of the air bag are welded with a vehicle frame girder, the upper parts of a hoisting air bag and a main air bag are connected with the upper seat of the air bag through a bolt, the lower part of the hoisting air bag is connected with the bearing bracket of the hoisting air bag through the bolt, the lower part of the main air bag is connected with the bearing bracket of the main air bag through the bolt, the bearing bracket of the air bag is connected with a vehicle axle through a U-bolt, and vehicle wheels are connected with the vehicle axle through the bolt. The air bag suspension has the lower natural vibration frequency, which can guarantee the better ride comfort and the freight security of the semi-trailer, thus being beneficial to enhance the vehicle speed and the transportation productivity. At the same time, because the impulsive load to the road surface in the running process of the vehicle is proportional to the square of the vibration frequency, the multiple differing by the square is about 2.5 times, the damage to the road surface can be greatly reduced when the vehicle runs, and the road service life is prolonged.
Description
Technical field
The utility model relates to a kind of superimposed trailer, i.e. the air bag suspension frame structure of three superimposed trailers.
Technical background
Three superimposed trailer suspension frame structures of tradition are the leaf spring suspension frame structure, and eigentone is 2.0 ∽ 2.7HZ, and oscillation frequency is higher, and the riding comfort of vehicle is relatively poor, and the safety of shipping goods is also influenced; Under equal load-carrying condition, the oscillation frequency height, road pavement is damaged also considerable influence.Load overbalance between three, load-carrying capacity reduces relatively, and brake compensation and safety weaken to some extent.When zero load or underloading, all be three wheel rollings, like this, wasted unnecessary resistance to motion and bend inharmonious degradation of energy that causes of motion and wear on tyres.
Summary of the invention
The purpose of this utility model is the draft hitch that a kind of three superimposed trailers newly will be provided, and adopts the air bag suspension frame structure.
The utility model is achieved in that gentle rami capsulares stand in the air bag seat of honour and chassis side rail welding, promote air bag and main gasbag top and air bag seat of honour bolt together, promote the air bag bottom and promote the air-bag support bolt together, main gasbag bottom and main gasbag support bolt together, air-bag support is connected with saddle clamp with axletree, wheel and axletree bolt together.
Owing to adopted technique scheme: the air bag suspension frame structure has lower eigentone, and eigentone is 1.25 ∽ 1.7HZ.Can guarantee the riding comfort that superimposed trailer is good and the safety of goods; Be beneficial to the raising speed of a motor vehicle, improve the transportation-production rate.Simultaneously, because square being directly proportional of impact load and the oscillation frequency of road pavement in the vehicle ', the multiple that its square differs is about 2.5 times, therefore, and the damage of road pavement in the time of can greatly reducing vehicle ', prolongation highway service life.
When zero load or underloading, primary shaft can promote, load by second and third axle bear, like this, the rolling resistance in the time of can reducing superimposed trailer and travel, and alleviate inharmonious degradation of energy that causes of turning motion and wear on tyres.
Description of drawings
Fig. 1 is a structural representation of the present utility model
In Fig. 1: 1, chassis side rail; 2, promote air bag; 3, promote air-bag support; 4, air-bag support seat; 5, main gasbag support, 6, main gasbag; 7, the air bag seat of honour; 8, axletree; 9, wheel.
The specific embodiment
The utility model is further described below in conjunction with embodiment.
In Fig. 1, gentle rami capsulares stand in the air bag seat of honour (1) (4) and chassis side rail (1) welding, promote air bag (2) and main gasbag (6) top and the air bag seat of honour (7) bolt together, promote air bag (2) bottom and promote air-bag support (3) bolt together, main gasbag (6) bottom and main gasbag support (5) bolt together, air-bag support (5) is connected with saddle clamp with axletree (8), wheel (9) and axletree (8) bolt together.
When the vehicle heavy duty, the main gasbag of three axles all is in inflated condition, the air bag elongation, and main gasbag, main gasbag support, air-bag support seat constitute the air spring suspension system, vehicle load is passed to the main gasbag support through the gentle rami capsulares stand of main gasbag, is delivered to axletree, wheel through the main gasbag support.Second, third main gasbag is an inflated condition always, and when vehicle zero load or underloading, the primary shaft main gasbag is in deflated state, promotes airbag aeration, and the air bag elongation by promoting the air-bag support leverage, promotes one, makes the front tyre built on stilts.
Claims (1)
1. three superimposed trailer air bag suspension frame structures, it is characterized in that gentle rami capsulares stand in the air bag seat of honour (7) (4) and chassis side rail (1) welding, promote air bag (2) and main gasbag (6) top and the air bag seat of honour (7) bolt together, promote air bag (2) bottom and promote air-bag support (3) bolt together, main gasbag (6) bottom and main gasbag support (5) bolt together, air-bag support (5) is connected with saddle clamp with axletree (8), wheel (9) and axletree (8) bolt together.
