Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0040] This embodiment discloses a suspension assembly with switchable elastic elements, a control method and a saddle structure used in conjunction with it, which can selectively make the air spring Or the leaf spring works alone, making the vehicle's transportation range and use environment wider. The elastic element switchable suspension assembly has two modes for selection, which are high ride comfort mode and high load carrying capacity mode. The lifting lugs are separated, and the ride comfort of the vehicle is better at this time. When it is necessary to transport large-tonnage cargo, the suspension can be adjusted to a high-carrying-capacity mode, and the leaf spring works alone at thi...

The invention discloses an elastic element switchable suspension assembly and a control method, the elastic element switchable suspension assembly comprises a driving oil cylinder bracket, a frame longitudinal beam, a steel plate spring front bracket, a steel plate spring, a lifting lug bracket, a lifting lug, an axle, a driving oil cylinder, a spring eye fixing pin, a control system and air springs which are symmetrically arranged along the central axis of the axle, and the steel plate spring is connected to the lower end of the axle; the lower end of the air spring is connected with the steel plate spring, the upper end of the air spring is connected with the frame longitudinal beam, the steel plate spring front support and the lifting lug support are connected with the two sides of the frame longitudinal beam respectively, the lifting lug is connected with the lifting lug support through a pin shaft, and the driving oil cylinder support is fixedly connected with the frame longitudinal beam. The spring eye fixing pin is connected with a driving oil cylinder piston rod, and the control system controls the air spring and the driving oil cylinder to act. Through operation of the control system, switching between a high load bearing capacity mode and a high smoothness mode can be realized. The suspension assembly solves the problem that in the prior art, a suspension assembly cannot give consideration to high bearing capacity and high smoothness at the same time.
Description
technical field [0001] The invention relates to a switchable suspension assembly of an elastic element and a control method, belonging to the technical field of automobile suspension. Background technique [0002] With the rapid development of the logistics and transportation industry, semi-trailer tractors have become the most widely used transport vehicles in the domestic market due to their economical and efficient features. Driving comfort and the ability to maintain the integrity of the cargo are in constant demand. [0003] Suspension assembly is the most important buffer and damping system of tractors. At present, the elastic components of tractor suspension assemblies in the industry mainly include leaf springs and air springs. Leaf spring is the most widely used suspension elastic element on traditional commercial vehicles. Its main features are simple structure, reliable operation, low cost and strong bearing capacity, but poor comfort. The air spring uses the co...
