Problems solved by technology

[0002] Vehicle suspension is the general term for all force-transmitting connection devices between the frame of the car and the axle or wheels. Or the impact force of the car body, and attenuate the vibration caused by it. The vehicle suspension determines the stability, comfort and safety of the vehicle. It is one of the key components of modern vehicles. Different suspension settings will make the driver feel different. Driving experience, a typical suspension structure is composed of elastic elements, guide mechanisms, and shock absorbers, and individual structures also have buffer blocks, stabilizer bars, etc. Elastic elements include leaf springs, air springs, coil springs, and torsion bar springs and other forms, the leaf spring is one of the most common elastic elements at present. The leaf spring is composed of superimposed steel plates with a certain shape. However, due to the limited load-bearing capacity of this type of leaf spring, in order to meet the load-bearing requirements of the vehicle, multiple steel plates are required. Composition, such a structure will not only increase the manufacturing cost of the vehicle suspension, but also increase the weight of the vehicle suspension

Embodiment 1

[0031] Such as Figure 1-3 As shown, a kind of vehicle suspension comprises vehicle frame 1, and described vehicle frame 1 is provided with lug 2, fixed support 3, front support 4, rear support 5, leaf spring assembly 6 and auxiliary support 7, and described auxiliary support 7 is located above the leaf spring assembly 6, the leaf spring assembly 6 is located between the rear bracket 5 and the front bracket 4, the front bracket 4 is located above the fixed bracket 3, and the rear bracket 5 is connected to the lifting lug 2 through a pin , the leaf spring assembly 6 is composed of an "m"-shaped leaf spring 8, one end of the "m"-shaped leaf spring 8 is connected to the lifting lug 2 through a pin, and the other end of the "m"-shaped leaf spring 8 is connected to the The front bracket 4 is connected by a pin shaft, and three sub-brackets 7 are corresponding to the top of the "m"-shaped leaf spring 8. The "m"-shaped leaf spring 8 is a one-time processing and forming structure, and...

Embodiment 2

[0034] Such as Figure 4-5 As shown, the present embodiment 2 is substantially the same as the present embodiment 1, and the difference is that the leaf spring assembly 6 is composed of an "8"-shaped leaf spring 9, and one end of the "8"-shaped leaf spring 9 is connected to the The front bracket 4 is connected by a pin shaft, the other end of the "8"-shaped leaf spring 9 is connected to the lifting ear 2 by a pin shaft, and the upper part of the "8"-shaped leaf spring 9 corresponds to 2 or 3 The sub-bracket 7, the "8"-shaped leaf spring 9 is a one-time processing and forming structure, and the structures at both ends of the "8"-shaped leaf spring cooperate with the sub-support, which can make the force of the "8"-shaped leaf spring more uniform , to enhance the bearing capacity of the "8"-shaped leaf spring, and one "8"-shaped leaf spring can replace the traditional use of multiple leaf springs superimposed, which can not only save manufacturing costs, but also reduce the cost...

Embodiment 3

[0036] Such as Figure 6-8 As shown, the present embodiment 3 is substantially the same as the present embodiment 1, and the difference is that the leaf spring assembly 6 is composed of a "P"-shaped leaf spring 10 and a "eight"-shaped leaf spring 11, and the " One end of the "eight"-shaped leaf spring 11 is connected to the rear bracket 5 through a pin shaft, and the other end of the "eight"-shaped leaf spring 11 is located above the "P"-shaped leaf spring 10, and the "P"-shaped plate One end of the spring 10 is connected to the lifting lug 2 through a pin shaft, and the other end of the "P"-shaped leaf spring 10 is connected to the front bracket 4 through a pin shaft, and the "P"-shaped leaf spring 10 and the Said "eight"-shaped leaf spring 11 is correspondingly provided with said sub-bracket 7, said "P"-shaped leaf spring 10 and said "eight"-shaped leaf spring 11 are all one-time processing molding structures, and the auxiliary bracket They are respectively used to enhance ...

Abstract

The invention relates to the technical field of vehicle engineering, in particular to a vehicle suspension. The vehicle suspension involves a frame, wherein the frame is provided with a lifting lug, afixing support, a front support, a rear support, a plate spring assembly and auxiliary supports, the auxiliary supports are located above the plate spring assembly, the plate spring assembly is located between the rear support and the front support, the front support is located above the fixing support, and the rear support is connected with the lifting lug through a pin shaft. According to the vehicle suspension, the auxiliary supports are located above the plate spring assembly, after the plate spring assembly is stressed and deformed, the plate spring assembly is in contact with the auxiliary supports, the auxiliary supports are used as force bearing supporting points for the plate spring assembly, so that the torque borne by the plate spring assembly is reduced and the bearing capacity of the plate spring assembly is enhanced; the rear support is connected with the lifting lug through the pin shaft, after the plate spring assembly is stressed and deformed, the lifting lug can be used for driving the plate spring assembly to move partially, so that the deformation of the plate spring assembly is released, the plate spring assembly is prevented from being damaged due to excessive deformation, and the bearing capability of the plate spring assembly is improved.
