Abstract
The utility model discloses a low chassis air suspension system. The comfort and smoothness of a vehicle under a driving state are improved by arranging an air spring (8) at the back end of a left steel plate spring (3) and the back end of a right steel plate spring (11), the impact to cargoes and road faces is reduced, maintenance of parts of the vehicle is facilitated, and the service life of the vehicle is prolonged.
Description
Technical field
The utility model belongs to the chassis system manufacturing technology field of road transport vehicle, specifically, relates to a kind of low chassis airsuspension system.
Background technology
Truck rear suspension mainly uses steel spring as elastic element at present, because steel spring rigidity is changeless, amount of deflection is directly proportional to load, in the time that Vehicle Driving Cycle is on rugged road surface, because moment impact is very large, the hysteresis phenomenon of leaf spring causes the uneven compliance of running car, and traveling comfort is by bus reduced, and also may make goods damage in the process of moving.In addition, adopt the suspension height of steel spring to change according to the difference of load, the height of suspension can not reduce, and brakes simultaneously and accelerate also to cause spring to twist.In addition, adopt the deadweight of Leaf Spring Suspension car load larger, increase oil consumption, be unfavorable for energy-saving and emission-reduction.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of low chassis airsuspension system that improves ride comfort and traveling comfort.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of low chassis airsuspension system, comprise vehicle frame, vehicle frame comprises left longeron and right vertical beam, also comprise left plate spring and right steel spring, described left plate spring at front end is connected with left longeron, and the leading portion of right steel spring is connected with right vertical beam, left plate spring rear end is connected with left longeron by air bellow, and right steel spring rear end is connected with right vertical beam by another air bellow;
Also comprise the vehicle bridge that is arranged on left plate spring and right steel spring near middle, and, the cross sill of connection left plate spring rear end and right steel spring rear end.
Described left plate spring and right steel spring near middle are equipped with a leaf spring undersetting, and vehicle bridge is fixed in left plate spring and right steel spring by leaf spring undersetting; Described leaf spring undersetting is provided with bumper, and two bumpers are connected with left longeron and right vertical beam respectively.
On described left longeron and right vertical beam, be provided with sunk structure with vehicle bridge correspondence position.
Also comprise the lateral rod that connects right vertical beam and vehicle bridge.
Described cross sill is provided with levelling valve.
Described left plate spring is connected with left longeron and right vertical beam by a flat spring bracket respectively with right steel spring, and described flat spring bracket is connected with left plate spring and right steel spring front end by lining.
Described bumper is connected with left longeron and right vertical beam by a connection bracket respectively.
The utility model has the advantage of, take Pneumatic Suspension as core, much no matter it has load, it is constant that vehicle body natural frequency keeps substantially, and static deflection and load-independent always keep constant feature, no matter and load is much, all can guarantee the corresponding ground Clearance.Improve traveling comfort and the ride comfort of vehicle under running state, reduce the impact to goods and road surface, be conducive to the maintenance of vehicle component, extend the service life of vehicle.Meet the requirement that reduces chassis and saddle height, can allow trailer within the scope of rules, reach the maximization of transport space, reduce car load deadweight simultaneously.
Accompanying drawing explanation
