Description
Technical field
The utility model relates to vehicle suspension, especially relates to a kind of adjustable length wishbone suspension.
Background technology
Suspension is one of vitals of automobile, suspension the road surface is acted on supporting power, propulsive effort, braking force, the lateral reaction of wheel and the transmission of torque that produced to car
FrameOn, relax the vibration of impact load, decay bearing system, thereby guarantee the vehicle ' ride comfort.
Wishbone suspension is generally by up and down two not isometric vee shapes or A font Control arm and column support type hydraulic pressure subtract
ShakeDevice constitutes, and upper suspension arm is shorter than Lower control arm usually.One end of upper suspension arm is connecting pillar and is subtracting
ShakeDevice, the other end is connecting vehicle body; One end of Lower control arm is connecting wheel, and the other end is then connecting vehicle body.Last Lower control arm is also linked to each other by a pipe link, and this root connecting rod yet is connected with wheel simultaneously.In whole suspension structure, improved the globality of last Lower control arm and whole suspension by connection to a plurality of fulcrums.If the vehicle of f-w-d, be assemblied in so double wishbone suspension on the front-wheel between last Lower control arm except that being equipped with transmission device, also have steering hardware, this makes its texture ratio not more complex with the trailing wheel of steering hardware.In steering hardware, steering yoke bolt determines that by connection location that turns to pallet and last Lower control arm and angle wheel flutter can rotate around stub, simultaneously also can be with the Lower control arm bob.Usually adopt bulb to connect the motion needs that satisfy front vehicle wheel in double wishbone suspension: the connecting portion of going up Lower control arm and steering yoke bolt should support front-wheel to realize turning to the shake up and down of controlling wheel again.But because the length difference problem of last Lower control arm, if this has also proposed acid test to the design of double wishbone suspension---the length difference of going up Lower control arm is too small, can cause left and right wheels apart from bigger than normal during the wheel shake, accelerates the outer lateral wearing of tire; Otherwise if the arm lengths difference is excessive up and down, camber angle is excessive in the time of then can causing wheel steering, makes lateral wearing quickening in the tire.Therefore, by increasing variation that the length that goes up Lower control arm reduces the variation of wheelspan and the control camber angle good method of can yet be regarded as.
But present wishbone suspension, its upper and lower transverse arm can not be adjusted length, then can not change the relative position between upper and lower transverse arm and the wheel column point of connection place, can't adjust the positional parameter (as Kingpin inclination angle, kingpin caster angle, camber angle etc.) of suspension stub.
Summary of the invention
Order of the present utility model is to provide a kind of upper and lower transverse arm can adjust length, can change the relative position between upper and lower transverse arm and the wheel column point of connection place, thereby reach a kind of adjustable length wishbone suspension of positional parameter, control tread change and the camber angle variation of adjusting the suspension stub.
The utility model is provided with Top Crossbeam, lower cross arm, push rod, swinging block and spring and subtracts
ShakeDevice; Top Crossbeam and lower cross arm all are in the shape of the letter V, the two ends of Top Crossbeam are provided with threaded connection and Top Crossbeam bearing, the two ends of lower cross arm are provided with threaded connection and lower cross arm bearing, threaded connection one end at Top Crossbeam two ends is rotationally connected by bolt pin and Top Crossbeam bearing, threaded connection one end at lower cross arm two ends is rotationally connected by bolt pin and lower cross arm bearing, and Top Crossbeam bearing and lower cross arm bearing all weld with outside vehicle frame; The push rod two ends all are connected with threaded connection, it is reverse that the threaded connection at push rod two ends is, the threaded connection of push rod one end is rotationally connected by the angled end of bearing pin and lower cross arm, the threaded connection of the push rod other end is rotationally connected by bearing pin and swinging block first end, swinging block second end is rotationally connected by bearing pin and jounce bumper one end, swinging block the 3rd end is provided with the swinging block bearing, swinging block and swinging block bearing are rotationally connected, swinging block bearing and the welding of outside vehicle frame, the jounce bumper other end and absorber seat are rotationally connected, absorber seat and the welding of outside vehicle frame.
Described Top Crossbeam bearing and lower cross arm bearing can be the transverse arm bearing of U font cross-sectional plane, and Top Crossbeam bearing and lower cross arm bearing one end and described bolt pin are rotationally connected, the Top Crossbeam bearing and the lower cross arm bearing other end and the welding of outside vehicle frame.
Described swinging block bearing bottom is the U character-shaped base, and swinging block bearing top is bolt pin, U character-shaped base and the welding of outside vehicle frame, and bolt pin passes described swinging block and is rotationally connected with swinging block.
It is that spherical rotation is connected that threaded connection one end at described Top Crossbeam two ends is rotationally connected by bolt pin and Top Crossbeam bearing, and it is that spherical rotation is connected that threaded connection one end at described lower cross arm two ends is rotationally connected by bolt pin and lower cross arm bearing.It is to be provided with globe bearing between threaded connection and bolt pin that described spherical rotation connects.
It is that spherical rotation is connected that the threaded connection of described push rod one end is rotationally connected by the bearing pin and the angled end of lower cross arm, and it is to be provided with globe bearing between threaded connection and the bearing pin that described spherical rotation connects; It also is that spherical rotation is connected that the threaded connection of the described push rod other end is rotationally connected with swinging block one end, and it is to be provided with globe bearing between threaded connection and the bearing pin that described spherical rotation connects.
Described swinging block is the triangle swinging block, and the triangle swinging block is worn to connect through 3 bearing pins by 2 blocks of steel plates triangular in shape and constituted, and 3 bearing pins are located at 3 angle ends of triangle swinging block respectively, and 3 angle ends are first end, second end and the 3rd end of described swinging block.
Because the two ends of Top Crossbeam and the two ends of lower cross arm are equipped with threaded connection, the push rod two ends are provided with oppositely directed threaded connection, therefore can be by rotating the threaded connection at Top Crossbeam two ends and lower cross arm two ends, just can change the left and right sides length of Top Crossbeam or lower cross arm, promptly change Top Crossbeam or/and the relative position at lower cross arm and wheel column point of connection place, thereby can overcome because the error that is produced in the processing and manufacturing process, and the positional parameter that makes the suspension stub reaches designing requirement (as 3 ° of swivel pin angles, 0.5 ° of wheel caster, outward camber-1 °).Can reduce the variation of wheelspan and the variation of control camber angle by the length that increases upper and lower transverse arm, can guarantee that wheel has desirable motion characteristics when Uneven road and load change, improve vehicle handling stability.As strengthen the cohesive resistance of vehicle, and reduce the rolling resistance of vehicle, reduce Tyte Wear simultaneously, prolong the service life of tire.In addition can just can make corresponding growth of push rod or shortening, subtract thereby can change push rod, swinging block and spring by rotating push-rod (because of the threaded connection at push rod two ends is reverse)
ShakeSpatial relation between the device is guaranteed compression deformation of the spring amount and balance position, reaches better to subtract
ShakeEffect.
