A link interconnects the lower control arm and one of the terminal ends of a vibration damper thereby defining a common axis B bisecting the link. The link has a monolithic construction and a generally uniform thickness. The vibration damper moves along the common axis to absorb vibration transferred from a road surface and through the wheel.
Description
Relevant application
The application is a non-provisional application, it is No.60/945 that requirement enjoys in the serial number of submitting on June 22nd, 2007,613 and be No.60/952 in the serial number that on July 26th, 2007 submitted to, the preceence of 089 U.S. Provisional Patent Application, its full content is with reference to being included in herein.
Technical field
The present invention relates to the suspension system of wheel of vehicle, and more specifically, relate to the wheel suspension that vertical shock absorber strut is housed, be used to absorb the vibration of also transmitting from the road surface by wheel.
Background technology
As the remainder of the system on the power actuated vehicle, suspension system is carried out complicated function.Suspension system keeps the wheel of power actuated vehicle to aim at travelling of power actuated vehicle, the motion when a limiting vehicle main body is travelled during turning round and when jolting, and provide steady and comfortable taking for passenger and chaufeur.A lot of suspension systems are arranged in the known prior art.Length arm (SLA) suspension system has been generally to have used for many years on domestically-made vehicle.In the SLA system, by steering swivel, ball-joint assembly and last Lower control arm, each is taken turns on the vehicle frame that all is connected to vehicle independently.
The wishbone suspension system provides many assemblies, such as vehicle frame, Lower control arm, upper suspension arm, the hub that is used for the support wheel assembly and the shock absorber of vehicle.Last Lower control arm comes with respect to power actuated vehicle as steady arm and the fixing position of suspension system and assembly thereof and be connected on the vehicle frame with lining, and this lining permission vehicle wheel component moves up and down independently in response to the ground-surface irregularity.
Have various suspension systems in the prior art, these suspension systems have at least one bar or link, are used to interconnect the vibration absorber that is installed between vehicle body and the Lower control arm.These systems can obtain instruction from people's such as people's such as the U.S. Patent No. 4,377,298 of authorizing people such as Finn, Kami U.S. Patent No. 4,583,759 and Smith U.S. Patent No. 5,375,870.For example, people's such as Finn U.S. Patent No. 4,377,298 discloses a kind of suspension system of wheel, and it has the vibration absorber that is installed between vehicle body and the Lower control arm.U-shaped hook that is formed by two metallic forms of a pair of supporting leg and reversed bending or yoke shape partly are connected to neck or the axle collar to engage vibration absorber.The U-shaped hook that people's such as Finn U.S. Patent No. 4,377,298 is instructed is failed the additional strengthening of instructing or advising limiting in the U-shaped hook, and needs a plurality of parts form the U-shaped hook.
For example, people's such as Kami U.S. Patent No. 4,583,759 has been instructed arm support structure on a kind of suspension, and it has the vibration absorber that is installed between a vehicle body and the underarm.The U-shaped hook is formed by metal forging, and has neck, and with mesh vibration resorber and a pair of supporting leg, described supporting leg extends to corresponding far-end and fastener is connected to described underarm.U-shaped hook in people's such as Kami the U.S. Patent No. 4,583,759 fails to instruct or suggestion limits an additional strengthening in the U-shaped hook, and needs many parts to form the U-shaped hook.And the U-shaped hook in people's such as Kami the U.S. Patent No. 4,583,759 is formed by metal forging, thereby has influenced the whole weight of system negatively.
Therefore, have the chance that is used to improve suspension system and manufacture method thereof, it will reduce the quality of U-shaped hook, thus influence that reduces to vibrate and final noise, for suspension system has increased structural integrity, and strengthened the performance of transmission system application with low-cost and high power capacity.
Summary of the invention
Suspension system of the present invention is aimed at the wheel assembly of self-propelled vehicle with travelling of self-propelled vehicle, limited the motion of self-propelled vehicle main body during turning round and when jolting, and provides steady and comfortable taking for passenger and chaufeur.This suspension system presents many constituent elementss, such as vehicle frame, Lower control arm, upper suspension arm, the hub that is used for the support wheel assembly or the axle and the shock absorber of self-propelled vehicle.The upper suspension arm of suspension system and Lower control arm and axle cooperation, axle and wheel shaft cooperation, it defines a rotation axis and is supporting vehicle wheel component.Shock absorber has first and second ends, one of them terminal and upper suspension arm cooperation.
Connecting rod or U-shaped hitcher have monolithic construction and common homogeneous thickness.Connecting rod interconnects second end of Lower control arm and shock absorber.Connecting rod and shock absorber limit a public axis altogether, and it is divided into two connecting rod and extends on the direction of the direction that is different from rotation axis.Shock absorber is along public axis is removable altogether, to absorb from the road surface also by taking turns the vibration of transmission.Connecting rod is the blank drawing that forms from metal, metal alloy and composite thereof.Connecting rod comprises neck and a pair of isolated supporting leg with the common circular cross section that is used to receive shock absorber.
Strengthening rib is deformed and enters in each supporting leg, thereby absorbs from the road surface and prevent the supporting leg bending during vibration by the wheel transmission when shock absorber.Strengthening rib further is deformed and enters neck, and is tapered away from far-end, to increase the intensity of connecting rod.When strengthening rib during from remote extension to neck, strengthening rib presents first width, and when supporting leg was deformed to neck, strengthening rib presented second width, and when strengthening rib further tapered on the neck, strengthening rib presented the 3rd width.Neck comprises terminal edge and the seam that extends betwixt.This sews up receiving connector, so that connecting rod is fixed on the shock absorber.Each supporting leg all presents one side, this mask have from this facing epitaxy stretch and near the tapered relative periphery edge of far-end, so that make far-end present usually smooth cross-sectional plane.
A kind of advantage of the present invention is that this connecting rod is formed by the metal sheet punching press for suspension system provides improved connecting rod, thus present in light weight, can be for replacing the known cast iron casting connecting rod of prior art.
Another kind of advantage of the present invention is for suspension system provides improved connecting rod, and it has reduced the quality of this connecting rod that is modified.
Another kind of again advantage of the present invention provides a kind of improved connecting rod, it has at least one strengthening rib, this strengthening rib is deformed each supporting leg that enters connecting rod, thereby when shock absorber absorbs from the road surface and prevents the supporting leg bending during vibration by the wheel transmission, and provide the integraty of structure for this connecting rod and whole suspension system.
Another advantage of the present invention provides a kind of improved mounting structure, is used for a left side and right suspension assembly parts are installed to vehicle body as one unit.
