Abstract
The utility model relates to a tank truck rear drive axle air suspension system which comprises L-shaped guide arms arranged on two sides respectively. The end portion of a vertical section of each L-shaped guide arm is connected with a truck frame through truck frame supporting while the end portion of a horizontal section of each L-shaped guide arm is connected with a cross beam component, the front portion of the horizontal section each L-shaped guide arm is connected with a damper, the other end of each damper is connected with the truck frame, air springs are arranged on two sides of the cross beam component, the other ends of the air springs are connected with the truck frame, each air spring is a film-type air spring and comprises an upper cover plate, a rubber air bag and a plunger from top to bottom, each rubber air bag is divided into an inner coating layer, a double-layer curtain layer and an outer coating layer, and each outer coating layer is a butadiene rubber layer. By the tank truck rear drive axle air suspension system, riding comfort of the whole truck is greatly improved, safety of the tank truck is greatly improved, transporting efficiency is improved, and damage to roads is reduced.
Description
Technical field
The utility model relates to air suspension of automobile field, is specifically related to a kind of Liquid Tank Motor Vehicle rear driving axle airsuspension system.
Background technology
Along with developing rapidly of industry and express highway, special-use vehicle has obtained fast speed development, such as Liquid Tank Motor Vehicle, Liquid Tank Motor Vehicle refers to tank container is housed, be used for loading and transporting liquid article the general designation of special tank vehicle, as truck tanker, LPG tank truck, acid (alkali) motor tank tuck, diet motor tank tuck etc., it has greatly improved and has transported efficiency in transportation, labour intensity and traffic cost are reduced, can adapt to the unappeasable various specific (special) requirements of some general wagons, greatly promote the development of communication and logistics industry; But part Liquid Tank Motor Vehicle is all installed the general wagon repacking of Leaf Spring Suspension System by forward and backward bridge at present, because vertical load is all born by steel spring, under different load, can there is different bendings in steel spring, cause vehicle frame always changing to the distance on ground, in addition the vibration isolation of this suspension system is poor, and ride comfort is bad.Also some Liquid Tank Motor Vehicle adopts full gas suspension, and normal load mainly contains air bag and bears, and have lightweight, traveling comfort and the good advantage of operational stability, but the ability of the anti-inclination of this suspension is poor.
Utility model content
The purpose of this utility model is exactly the defect existing for prior art, a kind of Liquid Tank Motor Vehicle rear driving axle airsuspension system is provided, the propons of itself and steel spring forms the suspension system of Liquid Tank Motor Vehicle jointly, has greatly improved the stability of car load and the ride comfort travelling.
Its technical scheme is: comprise the L shaped guide arm that both sides are respectively equipped with, connecting vehicle frame, horizontal segment are supported in its vertical section end end by vehicle frame is connected with transverse beam assembly; The front portion of described L shaped guide arm horizontal segment connects bumper, the other end connecting vehicle frame of bumper; The both sides of described transverse beam assembly are respectively equipped with air bellow, the other end connecting vehicle frame of air bellow; Described air bellow is diaphragm type air spring, and it comprises upper cover plate, rubber pneumatic bag and plunger from top to bottom, and described rubber pneumatic bag is divided into internal coating, Double-layer curtain layer of cloth and external coating from inside to outside, and described external coating is butadiene rubber layer.
Such scheme can further be improved to:
Described bumper adopts at right angle setting, and is arranged on the outside of vehicle frame, and described bumper is bitubular oil pressure damper or monotubular pneumatic bumper.
Described vehicle frame is supported for rubber bush, and the bumper that the upper end of described bumper connects described in L shaped guide arm by swivel coupling by constant-velocity universal joint connecting vehicle frame, lower end is bitubular oil pressure damper or monotubular pneumatic bumper.
The utility model is simple in structure, easy to manufacture, with low cost, reliable and stable, airsuspension system has that the natural frequency of vibration is low, rigidity is adjustable, vibrations and the advantage such as noise is little, long service life, greatly improve the ride comfort of car load, the safety of Liquid Tank Motor Vehicle is greatly enhanced, also improved conveying efficiency, alleviated the destruction of its road pavement simultaneously.
Accompanying drawing explanation
Fig. 1 is the connection diagram of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of air bellow in Fig. 1;
In figure: 1, vehicle frame, 2, vehicle frame supporting, 3, bumper, 4, L shaped guide arm, 5, air bellow, 6, transverse beam assembly, 7, constant-velocity universal joint; 5.1, upper cover plate, 5.2, external coating, 5.3, the 2nd layers of cord, 5.4, ground floor cord, 5.5, internal coating, 5.6, flange, 5.7 plungers.
The specific embodiment
With reference to Fig. 1-2, a kind of Liquid Tank Motor Vehicle rear driving axle airsuspension system, comprise the L shaped guide arm 4 that both sides are respectively equipped with, 2 connecting vehicle frames 1, horizontal segment are supported in its vertical section end end by vehicle frame is connected with transverse beam assembly 6, and vehicle frame supports 2 can be chosen as rubber bush; The front portion of L shaped guide arm 4 horizontal segments vertically connects bumper 3 by ball pivot, and the other end of bumper 3 is by the outside of constant-velocity universal joint 7 connecting vehicle frames 1, and bumper is bitubular oil pressure damper or monotubular pneumatic bumper; The both sides of transverse beam assembly 6 are respectively equipped with air bellow 5, the other end connecting vehicle frame 1 of air bellow 5; Air bellow 5 is diaphragm type air spring, it comprises upper cover plate 5.1, rubber pneumatic bag and plunger 5.7 from top to bottom, rubber pneumatic bag is divided into internal coating 5.5, Double-layer curtain layer of cloth 5.3-5.4 and external coating 5.2 from inside to outside, external coating 5.2 is butadiene rubber layer, and Double-layer curtain layer of cloth 5.3,5.4 is nylon yarn layer.The bottom of rubber pneumatic bag is provided with flange 5.6, is provided with the bead coil of the vulcanization of rubber, for reinforcement effect in it.
The utility model uses as the back axle of Liquid Tank Motor Vehicle, and jointly forms whole suspension system with the steel spring of propons, can greatly improve the stability of car load and the ride comfort travelling.
