Abstract

The utility model relates to a two-wheel drive front suspension of an economical passenger car, which solves the problem that parts for playing elastic element function and wheel steering function can be combined in a structural unit, so the inner space of the two front wheels is effectively increased. The front suspension comprises a cylindrical shock absorber, a front wheel hub, a front steering knuckle, a front stabilizer bar, a lower swing arm and a tie rod ball; the lower swing arm is shaped like an isosceles triangle, and two corners connected with the long side are respectively provided with a ball pin and a U-shaped lining; the third corner is provided with a circular lining; an upper bracket is arranged on the lower swing arm corresponding to the circular lining; the ball pin is connected with the lower end of the front steering knuckle; the upper bracket is connected with the tie rod ball of the front stabilizer rod, and the circular lining is connected with a fixed bracket of the lower swing arm; the U-shaped lining and the circular lining are all rubber linings. In the utility model, a subframe assembly in the traditional front suspension is removed; the structure satisfies the design principle of considering both light weight and reliability for economical passenger cars, and the relevant positioning parameters are enabled to be variable in a reasonable range.

Description

Economical manned vehicle two drives front suspension

Technical field

The utility model relates to a kind of Independent Suspension, specifically a kind of economy car front suspension.

Background technology

Suspension is the assembly of all transmission joints between vehicle frame and vehicle bridge or the wheel.It mainly acts on is a shear force and the moment of transfer function between wheel and vehicle body, and relaxes the impact load of being passed to vehicle body by uneven road surface, and the vibration of the bearing system that decay causes thus is to guarantee that automobile travels smooth-goingly.Suspension system will satisfy good ride comfort, suitable cushioning performance, good road-holding property and other ask for something.

At present, the front suspension of manned vehicle all is to adopt independent suspension basically, and the structure of a part of independent suspension is complicated, and as double wish-bone arm type etc., itself manufacturing cost is higher, and maintenance is also inconvenient; Though what part manned vehicle adopted is MacPherson type, but generally all be to use subframe to be fixedly connected on the vehicle body,, promote general assembly efficient though can reduce the influence of suspension system to body stiffness, but really increased manufacturing cost and made car load become heavy, its fuel economy all has certain influence.

Summary of the invention

For the part of all being born elastic element function and wheel guide function can be combined in the structural unit, actv. increases the space of two front-wheel inboards, satisfy the requirement of economical manned vehicle lightweight and reliability simultaneously, the utility model provides a kind of economical manned vehicle two to drive front suspension

The Technological improvement plan of realizing above-mentioned purpose is such:

Economical manned vehicle two drives front suspension and comprises cylinder type damper 1, front wheel hub 3, preceding steering swivel 2, front stabilizer bar 6, following swing arm 7 and tie rod ball 4; Before steering swivel 2 upper ends be connected with cylinder type damper 1, preceding steering swivel 2 and front wheel hub 3, bearing are compressed together;

Described down swing arm is the isoceles triangle shape, and its two jiaos of places that connect long limit are provided with ball pin 12 and U-shaped lining 11 respectively, and the third angle place is provided with round lining 10, also is provided with upper bracket 9 in the swing arm with circle lining 10 under cooresponding; Ball pin 12 is connecting preceding steering swivel 2 lower ends, and upper bracket 9 is connecting the tie rod ball 4 of front stabilizer bar 6, and circle lining 10 is connecting to descend swing arm fixed support 5.

Described U-shaped lining 11 is the U-shaped rubber bush.

Described round lining 10 is the round rubber lining.

The utility model is positioned at two-wheel drive automobile chassis frame front portion, its effect be the road surface act on vertical reaction on the tire, vertically counter-force and lateral reaction and transmission of torque that these counter-forces caused to vehicle frame, to guarantee the cruising of automobile.Its rational swing arm structure down, all parts of bearing elastic element function and wheel guide function be can be combined in the structural unit, actv. has increased the space of two front-wheel inboards, hang about being embodied in by rational bottom arm assembly design direct connection on vehicle body, save the subframe assembly in the traditional sense.This structure satisfies the principle of design that economical manned vehicle lightweight and reliability are taken into account, and the rigidity of front stabilizer bar is moderate, the located in connection parameter is changed change in a reasonable range.

The specific embodiment

The utility model is further described below in conjunction with drawings and Examples.

Embodiment:

Economical manned vehicle two drives front suspension and comprises cylinder type damper 1, front wheel hub 3, preceding steering swivel 2, front stabilizer bar 6, following swing arm 7 and tie rod ball 4; Before steering swivel 2 upper ends be connected with cylinder type damper 1, preceding steering swivel 2 and front wheel hub 3, bearing are compressed together; Cylinder type damper 1 upper end is by bolt, upper support assembly and body contact;

Following swing arm is the isoceles triangle shape, and its two jiaos of places that connect long limit are provided with ball pin 12 and U-shaped lining 11 respectively, and U-shaped lining 11 is the U-shaped rubber bush, and the third angle place is provided with round lining 10, and circle lining 10 is the round rubber lining; Ball pin 12 is connecting preceding steering swivel 2 lower ends, circle lining 10 is connecting to descend swing arm fixed support 5, connecting vehicle body by following swing arm fixed support 5, fixed support 8 after the swing arm under U-shaped lining 11 passes through, be that vehicle body is fixed in the swing arm rear end under being used for equally, play interval action, fixed support 8 plays the bulb of spherical hinge effect after the following swing arm.

Also be provided with upper bracket 9 in the swing arms down with circle lining 10 is cooresponding; Upper bracket 9 is connecting the tie rod ball 4 of front stabilizer bar 6, front stabilizer bar 6 is fixed on the vehicle body by lining, front stabilizer bar 6 assembly rigidity as stabilizer antiroll bar are moderate, and purpose is to reduce car load in the process of moving, lateral inclination that vehicle body produced and lateral angle vibration.
