Abstract
The utility model provides a MacPherson type suspension for automobiles consisting of a brake disc, a steering knuckle, two control arms, two vehicle frames, two control arm bushings, a steering tie rod, a connecting rod of a horizontal stabilizer bar, a horizontal stabilizer bar, a spring absorber assembly and an absorber bushing. Due to the fact that the two control arms replace one original control arm, and an intersected point connected by the two control arms replaces a hinged central point of the original control arms and knuckles, arm length of Kingpin twisting is shortened, shaking of a steering wheel on smooth-going road is effectively reduced, and the problem of accelerating deviation is solved.
Description
Technical field
The utility model relates to the car chassis system, relates in particular to a kind of automobile McPherson strut.
Background technology
The effect of suspension is flexibly wheel to be connected with vehicle body, transmit that all are vertical, vertically, power and the moment thereof of side direction, relax the impact from the road surface that in driving process, vehicle body is subject to, the vibration that decay causes thus, and play the guiding role, wheel is beated by the relative vehicle body of certain track, guarantee occupant's comfortable and goods intact.In automobile suspension system, whether interrelated according to the motion of left and right sides wheel, can be divided into dependent suspension and the large type of independent suspension two.Wherein, independent suspension is relatively independent due to the movement relation with left and right sides wheel, vehicle running smoothness is higher, can provide for driving engine the advantages such as greater room to be widely used.
McPherson strut is a kind of typical independent suspension, as shown in Figure 1A-1B.Mainly by steering swivel 1 ', Control arm 2 ', tierod 3 ', Panhard rod 4 ', Panhard rod connecting rod 5 ', mounting bush 6 on shock absorber ', jounce bumper assembly 7 ' and brake disc 8 ' formation.Steering swivel 1 ' with jounce bumper assembly 7 ' be bolted, steering swivel 1 ' with brake disc 8 ' be connected by bearing; Control arm 2 ' outer end by spherical hinge 21 ' with steering swivel 1 ' be connected, Control arm 2 ' the inner is connected with the subframe (not shown) by lining; Tierod 3 ' with steering swivel system (not shown) and steering swivel 1 ' be connected; Two ends, Panhard rod 4 ' left and right respectively with Panhard rod connecting rod 5 ' by spherical hinge, Panhard rod 4 ' middle part and subframe are connected and Panhard rod 4 ' be connected by the rubber bush (not shown); Panhard rod connecting rod 5 ' with Panhard rod 4 ' with jounce bumper assembly 7 ' be connected; Mounting bush 6 on shock absorber ' be connected with vehicle body vibration damping tower (not shown), brake disc 8 ' outer sheathed wheel (not shown).Due to part guiding mechanism and jounce bumper assembly 7 ' be integrated together, therefore structure is simplified, also provide than large space for driving engine is horizontal, have simultaneously lightweight, low cost and other advantages, therefore be widely used in preposition forerunner's automobile.
But, be subject to the restriction of chassis layout and himself physical structure due to McPherson strut, can't with Control arm 2 ' spherical hinge 21 ' arrange too closely with wheel, cause stub disturbance brachium (L as shown in Figure 5) to be difficult to accomplish very short, generally between 55mm to 65mm, the steering wheel vibration when easily producing smooth-going road traveling and accelerate deviation phenomenon.Major cause is: during high vehicle speeds, wheel tyre and brake disk assembly produce the centnifugal force that rotates around the stub disturbance arm cycle due to the unbalance dynamic meeting, and this centnifugal force can decompose vehicle above-below direction and fore-and-aft direction.The periodic centnifugal force of above-below direction can make vehicle produce vertical shake, but due to have jounce bumper assembly 7 ' and resilient bushing 6 of being connected with vehicle body ', can isolate preferably this vibration.The periodic centnifugal force of fore-and-aft direction produces cyclic torque by stub disturbance arm to steer axis, makes bearing circle produce vibration, and stub disturbance arm is longer, and the moment to steer axis is larger, and the vibration on bearing circle is stronger.When vehicle accelerates, the propulsive effort of transmission shaft at the wheel center place also can produce the torque around main pin axis, the longer torque of stub disturbance arm is larger, when the left and right wheels output torque differs in size or left and right sides disturbance brachium when not waiting, can cause left and right sides not wait around the level of torque of main pin axis, bearing circle is rotated, cause running out the way.Stub disturbance arm is longer, and larger to drive torque, sideslip is more serious.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of shortening stub disturbance arm lengths is provided, and reduces the bearing circle shake on smooth-going road surface, improves the automobile McPherson strut that accelerates the sideslip problem.
the technical solution of the utility model provides a kind of automobile McPherson strut, comprise brake disc, steering swivel, Control arm, body support, the Control arm lining, tierod, the Panhard rod connecting rod, Panhard rod, the jounce bumper assembly, the shock absorber lining, described brake disc is connected by bearing with described steering swivel, described steering swivel is connected by spherical hinge with the outer end of described Control arm, the top of described steering swivel and described jounce bumper assembly are bolted, the side of described steering swivel and described tierod are connected through the hinge, one end of described Panhard rod connecting rod is connected with Panhard rod by spherical hinge, the other end of described Panhard rod connecting rod is connected with the jounce bumper assembly by spherical hinge, described shock absorber lining is arranged on the top of described jounce bumper assembly, described Control arm, described body support and described Control arm lining all have two, described Control arm comprises the first Control arm and the second Control arm, described the first Control arm and described the second Control arm are arranged on respectively the bottom of described steering swivel, the extended line of described the first Control arm and described the second Control arm intersects and is acute angle, described the first Control arm be connected the second Control arm and be connected with one of them described body support by one of them described Control arm lining respectively.
Preferably, the angle between the extended line of described the first Control arm and described the second Control arm is 30 °-60 °.
Preferably, the angle between the extended line of described the first Control arm and described the second Control arm is 45 °.
After adopting technique scheme, has following beneficial effect: owing to having replaced a traditional Control arm with the first Control arm and the second Control arm, the hinge center-point that has replaced former Control arm and steering swivel with the intersection point of the first Control arm and the second Control arm line, shortened stub disturbance brachium, the problem of accelerating sideslip has been shaken, solved to the bearing circle that has effectively reduced smooth-going road surface.
