Abstract
The invention discloses a vehicle rear suspension, comprising a multi-linkage mechanism; wherein, the mechanism is provided with a guide arm which is a hydraulic mechanism and comprises a hydraulic cylinder and a piston pulling rod. The multi-linkage suspension of the invention is provided with the guide arm which constitutes part of a suspension system and is also an execution element of a steering hydraulic loop, and implements the harmonic control between 4WS and the suspension, thus improving the performance of a chassis to utmost extent.
Description
Technical field
The present invention relates to a kind of rear suspension for automobile.
Background technology
Suspension is that vehicle is exercised the important composition system in the system, and it directly affects the stability of car load, operability and traveling comfort.By the front and back wheel of control, can divide front suspension, rear suspension.The rear suspension kind is a lot, torsion bar type, trailing arm type, double wish-bone arm type, many link-types or the like are arranged, wherein five link-types also are the rear suspension forms that medium-to-high grade car is often selected for use, and according to car different characteristics and parameter separately, five link-type rear suspensions of different automobile types all have nothing in common with each other.
Usually vehicle design is two front-wheel steerings, but in order to improve operational stability and to dwindle turn radius, rear-axle steering also enters people's the visual field, both four-wheel steering (being designated hereinafter simply as 4WS).Traditional 4WS mentality of designing be postpone front-wheel steering track and come, the downside design and installation that reaches at rear linking rod has the rack-and-gear of electrical motor driven or the steering box of other form, the design of steering box both sides has the intermediate rod of similar control front-wheel steering, makes the both sides intermediate rod form steering trapezium control rear-axle steering by the rotating of ECU control electro-motor.
Rear-axle steering is not to be controlled by chaufeur, turn to but exercise the positive anti-phase of information trace control trailing wheel by the ECU collection vehicle, the rear suspension that the shortcoming of this quasi-tradition 4WS is beated for the steering swivel system and the control trailing wheel of control rear-axle steering is two independent cover systems, each other in design, there is not association in mechanical mechanism and the control, so not only complex structure, control difficulty are big, and improve limited to the handling stability on chassis.
Summary of the invention
The present invention proposes at this technology just, and purpose is a kind of simple in structure, automobile-used rear suspension that set turns to of design.
The objective of the invention is to be achieved through the following technical solutions:
A kind of rear suspension for automobile comprises multi-connecting-rod mechanism, wherein is provided with a guide arm, and described guide arm is a hydraulic gear, comprises hydraulic actuating cylinder and pitch brace, and described hydraulic actuating cylinder and pitch brace be auxiliary connection vehicle frame and wheel steering joint separately.
Wherein, described multi-connecting-rod mechanism is a five-bar mechanism, and this five-bar mechanism also comprises draft arm, upper arm, underarm and trailing arm.
Perhaps, described multi-connecting-rod mechanism is four-bar linkage or six bar mechanism.
And the hydraulic circuit of oily rail and electronic control valve composition is connected at the head and the tail two ends respectively on the hydraulic actuating cylinder.
In addition, described guide arm is positioned on the steering swivel place away from wheel axis.
Positive progressive effect of the present invention is: at multi-link lever suspension fork guide arm being set, both having formed a suspension system part, is the power element in steering hydraulic loop again, has realized the co-operative control of 4WS and suspension, thereby can improve the chassis performance to greatest extent.

The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
A kind of rear suspension for automobile, one of them five-bar mechanism, this five-bar mechanism comprise draft arm 2, upper arm 3, underarm 4, trailing arm 5 and guide arm 6, described guide arm is a hydraulic gear, comprises hydraulic actuating cylinder 6b and pitch brace 6a.Guide arm 6 two ends are connected with subframe 1 by ball pin and wheel steering joint 8 respectively.
Wherein draft arm 2, upper arm 3, underarm 4, trailing arm 5 are rigid arm, and its two ends rubber bush by setting rigidity or ball pin respectively are connected with subframe 1 with wheel steering joint 8 separately; Guide arm 6 is formed hydraulic circuit with the Electronic Valve that has electro-motor, that is, be connected with steering control system, provides instruction by ECU according to concrete vehicle enforcement information, each mode of operation of control Electronic Valve, thus realize best trailing wheel control by guide arm 6.Described guide arm is positioned on the steering swivel place away from wheel axis, thereby obtains bigger moment.Described electronic control valve can be an electromagnetic valve, is prior art.
The mounting means of above-mentioned five connecting rod suspensions and subframe and steering swivel is described below in conjunction with Fig. 2, Fig. 3, Fig. 4.
Described " the inner " is meant the end near subframe, and described " outer end " is meant the end near steering swivel.
, below the rear wheel axis, reach from the visible guide arm 6 of Fig. 2 birds-eye view direction at vehicle rear wheel axis rear.In Fig. 5, the hydraulic actuating cylinder 6b of guide arm 6 is inboard to be connected with subframe 1 (being vehicle body) by the 3rd ball pin 6b1, and the first and last end design among the hydraulic actuating cylinder 6b has two hydraulic fluid port 6b2,6b3 that connect Electronic Valve, and oil pipe and Electronic Valve are all not shown.Fig. 6, Fig. 7 are respectively hydraulic actuating cylinder 6b, pitch brace 6a structural representation.
When Electronic Valve control fluid such as the work of Fig. 8 state, work fluid is pumped into by hydraulic fluid port 6b2 high pressure, enter the piston 6a2 of hydraulic actuating cylinder 6b high-voltage oil liquid promotion afterwards pitch brace 6a, make pitch brace 6a do extensional motion as shown, the low pressure oil in hydraulic actuating cylinder 6b left side is then by hydraulic fluid port 6b3 blowback oil storage kettle simultaneously; This moment pitch brace 6a connection wheel steering joint 8 the 9th connecting portion 86 places the second ball pin 6a1 also in the extensional motion of pitch brace 6a in the lateral movement of turning left of Fig. 8 direction, realize the wheel right steering thus, be benchmark with Fig. 1 direction; Otherwise when pitch brace 6a does compression movement, then driving wheel and do left steering, is benchmark with Fig. 1 direction.
Obviously,, also hang and realize the present invention, hang or the suspension of six connecting rods as four connecting rods at other many connecting rods for persons skilled in the art.And described hydraulic gear also can be replaced with air-actuator or electromagnetic mechanism.
