Description
Technical field
The utility model relates to a kind of pair of vehicle bridge Leaf Spring Suspension System, particularly, relates to a kind of two vehicle bridge Leaf Spring Suspension System that have equalizing gear.
Background technology
At the bigger automobile of some load carrying abilities (typically, heavy duty truck for example), because the bearing capacity of these automobiles is bigger, therefore propons and/or the back axle at automobile adopts two vehicle bridge structures, correspondingly, the suspension system of this pair vehicle bridge structure employing is called two vehicle bridge Leaf Spring Suspension System.
So-called two vehicle bridge Leaf Spring Suspension System promptly are furnished with two steel springs corresponding to two vehicle bridge in the both sides of automobile suspension system respectively along the longitudinal direction of automobile.As required, the forward and backward bridge suspension system of automobile all can adopt two vehicle bridge Leaf Spring Suspension System.For example, with regard to the propons Leaf Spring Suspension System, general single bridge suspension system is only arranged a steel spring respectively in the both sides of suspension system, thereby arranges two steel springs altogether.But, for two propons Leaf Spring Suspension System, arrange two steel springs respectively corresponding to two propons, thereby arrange four steel springs altogether in the both sides of suspension system.
Double steel plate spring suspension system in the market mainly adopts the uncorrelated vertical Leaf Spring Suspension System of putting.For example, Fig. 1 shows the basic structure of existing pair of vehicle bridge Leaf Spring Suspension System one side.This pair vehicle bridge Leaf Spring Suspension System comprises parts such as first steel spring 1, second steel spring 2, shock absorber J, Panhard rod P and mounting bracket, wherein, first steel spring 1 and second steel spring 2 are installed on the vehicle frame 1 by the longitudinal direction of three mounting brackets along vehicle frame 3.
From above-mentioned existing pair of vehicle bridge Leaf Spring Suspension System as can be seen, first steel spring 1 of this pair vehicle bridge Leaf Spring Suspension System and second steel spring 2 are independent mutually, and the load of two vehicle bridge differs bigger in that automotive wheel is upper and lower when beating.For example, suppose that the two vehicle bridge Leaf Spring Suspension System among Fig. 1 are two front axle suspension systems, when the wheel of first steel spring, 1 pairing first propons is subjected to ground-surface and upwards impacts, this first propons upwards compresses first steel spring 1, thereby the axle load moment increase that the propons of winning is born, the friction moment aggravation of the wheel of road surface and this first propons, and this moment since the wheel of second propons do not impacted, therefore this second propons does not upwards compress second steel spring 2, thereby the axle load of second vehicle bridge is relatively steady, and there is not the phenomenon of moment aggravation in the wheel of this second vehicle bridge and ground-surface friction at this moment.Thereby, in these traditional two vehicle bridge Leaf Spring Suspension System, because first steel spring 1 and second steel spring 2 are separate, bearing load is inconsistent each other to cause two vehicle bridge, therefore make auto tire wear inhomogeneous, and the ride comfort of whole automobile suspension system is relatively poor, and the ride comfort of automobile suspension system then directly has influence on the travelling comfort of car load.
The utility model content
Technical problem to be solved in the utility model provides a kind of pair of vehicle bridge Leaf Spring Suspension System, the axle load that this suspension system can make two vehicle bridge bear when wheel is beated is consistent substantially, thereby make that the wearing and tearing of automotive wheel are even as far as possible, and improve the ride comfort of automobile suspension system.
For solving above-mentioned technical matters of the present utility model, the utility model provides a kind of pair of vehicle bridge Leaf Spring Suspension System, this suspension system is provided with first steel spring and second steel spring in the both sides of automobile, this first steel spring and second steel spring are by being fixed on leaf spring first mounting bracket on the vehicle frame, leaf spring second mounting bracket and leaf spring the 3rd mounting bracket and be connected in described vehicle frame, wherein, one end of described first steel spring is installed on described leaf spring first mounting bracket, the other end is installed on first swinging mounting, this first swinging mounting is pivotably mounted on described leaf spring second mounting bracket, one end of described second steel spring is installed on described leaf spring second mounting bracket, the other end is installed on second swinging mounting, this second swinging mounting is pivotably mounted on described leaf spring the 3rd mounting bracket, be provided with trammel beam between wherein said first swinging mounting and described second swinging mounting, the two ends of this trammel beam are pivotably connected to respectively on described first swinging mounting and described second swinging mounting.
By technique scheme of the present utility model, because by described first swinging mounting, trammel beam, the 3rd swinging mounting has been realized the interlock of first steel spring and second steel spring, during i.e. first steel spring motion, second steel spring is correspondingly moved, thereby make two vehicle bridge common bearing load when vibration takes place automobile that is connected in first steel spring and second steel spring, the load that two vehicle bridge are born is consistent all the time substantially, so not only can make the wearing and tearing of motor tire more even, improve the service life of tire, and the ride comfort of whole suspension system is improved greatly, thereby make the corresponding raising of travelling comfort of car load.Moreover, owing to making described first steel spring and the common bearing load of second steel spring, therefore first steel spring and second steel spring can adopt the less steel spring of reed (promptly so-called " few sheet spring "), thus the manufacturing cost that can save automobile.
