Abstract
The utility model relates to two-wheel drive rear suspension of an economical passenger car, which solves the problems that the number of system parts of rear suspension needs to be reduced, and the system weight needs to be reduced. The two-wheel drive rear suspension of an economical passenger car comprises a cylindrical shock absorber, a rear steering knuckle, a rear wheel hub, a rear suspension arm assembly, a rear pull rod and a transverse stabilizer bar; wherein, the cylindrical shock absorber is also used as the brace strut of the suspension; the rear suspension arm assembly comprises two lower swing arms; each lower swing arm body is shaped like a channel steel, and one end thereof is provided with a rubber lining, and the other end is provided with a mounting hole; the mounting hole ends of the two lower swing arms are respectively connected with the rear steering knuckle; the rubber lining ends of the two lower swing arms are respectively connected with a vehicle body floor through bolts. In the two-wheel drive rear suspension of an economical passenger car, a subframe in the prior art is removed; the number of parts used in the whole system is reduced; the weight is lighter, space is saved, and the cost is lower. Based on the reasonable design of rubber lining rigidity, the force application situation of elements of the suspension is reasonably distributed; so the economical passenger cars are ensured to have good operational stability and running smoothness.
Description
Technical field
The utility model relates to a kind of suspension system of automobile, is that economical manned vehicle two drives rear suspension specifically.
Background technology
At present, what the rear suspension of economy car much still adopted is dependent suspension, and aspects such as its ride comfort and traveling comfort all have to be hoisted; Though part manned vehicle adopts the independent suspension that has subframe, but generally all be to use subframe to be fixedly connected on the vehicle body, though can reduce the influence of suspension system to body stiffness, promote general assembly efficient, but really increased manufacturing cost and made car load become heavy, its fuel economy all has certain influence, and is not satisfactory for economy car cost aspect.
Summary of the invention
In order to reduce rear-suspension system number of parts, mitigation system weight, to guarantee that automobile has good road-holding property and riding comfort, the utility model provides a kind of economical manned vehicle two to drive rear suspension.
Concrete structural design scheme is as follows:
Economical manned vehicle two drives rear suspension and comprises cartridge type rear shock absorber 4, back steering swivel 7, rear-wheel hub 6, back boom assembly 2, back propelling rod 3 and Panhard rod 1.
The cartridge type rear shock absorber 4 double struts of making suspension, the upper end of cartridge type rear shock absorber 4 is installed on the vehicle body, the lower end is connected to steering swivel, be connected on the vehicle body by control stalk again, the main pin axis of cartridge type rear shock absorber 4 is the line at hinge center up and down, when the wheel bob, can guarantee that the variation of its four wheel locating parameter is minimum, the adjustment of the eccentric bolt that the trailing wheel toe-in can be by back boom and body contact place reaches designing requirement; Back steering swivel 7 is connecting rear-wheel hub 6.
The back boom assembly comprises two following swing arms, bottom arm body is the channel-section steel shape, and the one end is provided with rubber bush, and the other end is provided with mounting hole, the installation nose end of two following swing arms connects the rubber bush end of 7, two following swing arms of back steering swivel respectively and body bottom panel by bolted connection respectively; Panhard rod 1 two ends are connected on the back boom assembly 2 by the damp connecting lever assembly.
Useful technique effect of the present utility model is: the double strut of making suspension of cartridge type rear shock absorber, and the upper end of cartridge type rear shock absorber is installed on the vehicle body, and the lower end is connected to the back steering swivel, is connected on the vehicle body by control stalk again; Save in the traditional sense by the type of attachment of subframe, the used part of total system is less, and weight is low weight, can save the space, and cost is also relatively more cheap.Rear suspension assembly and Panhard rod, when body inclination, suspension distortion in both sides does not wait, and Panhard rod will play similar leverage, to reduce the inclination and the vibration of vehicle body, improves the stability that car travels.Utilization is to the appropriate design of rubber bush rigidity, and the stressing conditions of each element of suspension that rationally distributes guarantees that automobile has good road-holding property and riding comfort.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is following swing arm structure scheme drawing,
Fig. 3 is rear-wheel hub and back steering swivel connection diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, economical manned vehicle two drives rear suspension and comprises cartridge type rear shock absorber 4, back steering swivel 7, rear-wheel hub 6, back boom assembly 2, back propelling rod 3 and Panhard rod 1.
The cartridge type rear shock absorber 4 double struts of making suspension, the main pin axis of cartridge type rear shock absorber 4 is the line at hinge center up and down, the upper end of cartridge type rear shock absorber 4 is installed on the vehicle body, the lower end is connected to back steering swivel 7, be connected on the vehicle body by control stalk again, when the wheel bob, can guarantee that the variation of its four wheel locating parameter is minimum, the adjustment of the eccentric bolt that the trailing wheel toe-in can be by back boom and body contact place reaches designing requirement; Back steering swivel 7 is connecting rear-wheel hub 6.
Back boom assembly 2 comprises two following swing arms, bottom arm body 9 is the channel-section steel shape, and the one end is equipped with rubber bush 8, and the other end is provided with mounting hole, the installation nose end of two following swing arms connects back steering swivel 7 respectively, and on the back steering swivel 7 of the installation nose end junction of two following swing arms rubber bush is housed; Rubber bush 8 ends of two following swing arms body bottom panel by bolted connection respectively; Back boom assembly 2 and back distance rod assembly 3 are the carrier between vehicle body and the suspension, and back distance rod assembly 3 two ends also are connected with vehicle body and knuckle assembly 7 respectively, and above junction all has lining at interval, plays the effect of buffering and vibration damping.
Panhard rod 1 rigidity of stabilizer antiroll bar is moderate, and its two ends are connected on the back boom assembly 2 by the damp connecting lever assembly, and purpose is to reduce car load in the process of moving, lateral inclination that vehicle body produced and lateral angle vibration.
It is good that the rubber bush of back boom assembly 2 and back steering swivel 7 installation ends has an anti-vibration performance, and advantages such as flexible characteristic and attenuation characteristic, is indispensable critical elements in the utility model, guarantees that finally car load has good road-holding property and ride comfort.
