Vehicle suspension devices and vehicle equipped therewith

Abstract

The invention provides vehicle suspension devices and a vehicle equipped therewith. The vehicle comprises a vehicle body and at least one pair of wheels arranged below the vehicle body. Each vehicle suspension device corresponds to one of the wheels and comprises a suspension spring structure, a suspension bracket and a main bearing, wherein each suspension spring structure is arranged above the corresponding wheel; a first position of each suspension bracket is connected to the other end of the corresponding suspension spring structure; a second position of each suspension bracket is connected to the corresponding wheel; and each main bearing is connected between the corresponding suspension bracket and the vehicle body. By arranging the suspension devices directly above the wheels, the vehicle suspension devices and the vehicle equipped therewith are capable of increasing the distance between the two suspension devices on the left and right, improving the suspension performance and reducing the height of center of gravity of the whole vehicle, thereby improving the running stability of the vehicle. In addition, the vehicle suspension devices and the vehicle equipped therewith increase the distance between the left and right wheels and omit a vehicle axle so as to greatly reduce the height of a bottom plate of a vehicle container and even enable the bottom plate to be close tothe ground, thereby increasing the storage space of the vehicle and improving the space utilization.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension, in particular to a vehicle suspension device for improving suspension performance and driving stability of a vehicle and a vehicle comprising the same. Background technique [0002] The vehicle suspension device refers to a force transmission support structure between the vehicle body and the wheels. Its main function is to support the vehicle body, buffer the impact force transmitted from the uneven road to the frame or the vehicle body, and attenuate the vibration caused by it. To improve the feeling of riding, and ensure that the car can run smoothly. Different suspension devices will give the driver different driving experience. The suspension device determines the driving stability, riding comfort and safety of the vehicle, and is one of the key components of the vehicle. [0003] Such as figure 1 Shown is a schematic structural diagram of a vehicle using a vehicle suspension de...

AI Technical Summary

Problems solved by technology

[0004] from figure 1 It can be seen from the figure that, adopting this structure, on the one hand, in order to connect the vehicle suspension device 101 and the wheels 1041, a very long axle 1049 needs to be set between the left and right wheels 1041, and the setting of the vehicle suspension device 101 occupies the left and right sides. The large space between the two wheels 1041, the existence of the axle 1049 and the vehicle suspension device 101 limits the height of the floor of the vehicle compartment 1044, so that the center of gravity 1045 of the vehicle will remain at a relatively high height, which has great influence on the stability of the vehicle. big impact

On the other hand, when the vehicle suspension device is applied to a truck or a trailer, the vehicle compartment 1044 is used as a compartment, and the height of the compartment has to be set high due to the limitation of the axle 1049 and the suspension device 101.

At the same time, in order to meet the restrictions on vehicle height in relevant regulations or standards, the overall storage space of the compartment is relatively small, and the cargo capacity is small

When this type of vehicle is applied to the transportation of goods, the smaller capacity will lead to an increase in the number of transportation, which will lead to an increase in transportation costs
