Description
Technical field
The present utility model application is related to electric automobile suspension, more particularly to shock absorption assembly before a kind of automobile.
Background technology
MacPherson type suspension is made up of helical spring, telescopic shock absorber, A font lower swing arms, and most vehicles can also add
Upper QS.The physical arrangement of McPherson strut is that column support type damper doubles as stub, bears to come from vehicle body shake
With the upper lower prestress of ground shock, knuckle（Also wheel can be said, because knuckle acts on wheel）Then rotated along stub；
In addition, its stub is swingable, feature is that stub position and front wheel alignment angle change with the bob of wheel, and front wheel alignment
Change small, possess good riding stability.Because McPherson is suspended in the motion such as steering or front wheel bouncing, kingpin inclination
It is continually changing, i.e., main pin axis have also attached the swing of axis when turning to except rotating, and can only be relied on electric automobile
Gap and center-pole between damper upper installing hole position and damper center-pole deflect or as utilizing rubber on fuel-engined vehicle
Glue is deformed to make up the requirement that single degree of freedom structure provides the dual free degree, i.e. suspension upper end itself and vehicle frame is not over gold
Category is directly connected to.It is so bringing as a result, steering can be realized substantially, but rely on be material deformation to adapt to turn to when stub
The change of axial location, it can substantially feel that steering drag dynamics changes when being deformed due to material, steering procedure is not smooth enough,
Especially when vehicle front portion load is heavier, steering drag is particularly evident, or even the phenomenon of rubber tear or center rod bending occurs.
Utility model content
The utility model provide a kind of center-pole can self-adapting steering when axis change automobile before shock absorption assembly,
Shock absorption assembly is flexible coupling when being turned to be applicable by using rubber present in main pin axis change in location before solving automobile
Steering it is not smooth enough the problem of.
Above technical problem is that solved by following technical proposal：Shock absorption assembly before a kind of automobile, including cartridge type damping

It is single practical.
As it is another preferably, the attachment structure includes suspension groove and the suspension pin that is located in epimere, the suspension pin
Both ends be connected in the both sides side wall of the suspension groove.In use, suspension groove is integrally formed or other modes are arranged on car
On frame.
Preferably, the attachment structure also includes suspension pin motor, the correlation photoelectricity that driving suspension pin rotates
Switch and motor control unit, the suspension pin are cylinder, and the suspension pin is provided with circumferentially equally distributed along suspension pin
Light barrier, the light barrier are provided with loophole, and the correlation optoelectronic switch includes Switch main body and speculum, and the switch is originally
Body and speculum are axially distributed in the both sides of light barrier along suspension pin, described in when the linearity of the suspension pin is in setting range
The light that Switch main body is sent can enter speculum described in the loophole directive, and the linearity of the suspension pin exceeds setting range
The light that the Switch main body is sent when interior is blocked by the light barrier；The light of Switch main body transmitting is from can be by described
To during the change sheltered from by light barrier, the motor control unit controls described in the suspension pin motor driving loophole
Suspension pin rotates 180 °.Influenceed normal because the concussion up and down being subject to during use can cause suspension pin flexural deformation excessive
Use, the technical program then enables to suspension pin to rotate 180 °, utilize vibrations when producing the bending more than sets requirement
It is more straight that power make it that realization is carried out to suspension pin.
Preferably, the power output shaft of the suspension pin motor is coaxially connected together with the suspension pin, institute
It is stepper motor to state suspension pin motor.It more convenient can be accurately controlled the rotational angle of suspension pin.
The utility model tool has the advantage that：Enable to damper between vehicle frame using being rigidly connected, so as to realize
Improve the service life of tie point.Steering can be made more smoothly and steady, and steering drag can be reduced；Existing scheme is sometimes
Even occurs noise during steering, the technical solution of the utility model is then without this steering noise；It is existing when by side collision
Structure is very fragile, easily produces damper and is hit curved or connection obscission, and the technical solution of the utility model is then alleviated
This problem.

Onto thread head 51, rotating oscillation damping device fixing nut 8 causes damper fixing nut 8 to coordinate support level 52 to step up vehicle frame, from
And realize connection of the utility model with vehicle frame.
Embodiment two, the difference with embodiment one are：
Referring to Fig. 2, attachment structure 5 includes suspension groove 53, suspension pin 54, suspension pin motor 55, correlation photoelectricity and opened
Close 56 and motor control unit 57.Suspension groove 53 is formed in one using on vehicle frame of the present utility model.Suspension pin 54 is circle
Pin.Suspension pin 54 is located in epimere 32.The both ends of suspension pin 54 are connected in the both sides side wall of suspension groove 53.Suspension pin is driven
Dynamic motor 55 is fixed on suspension groove 53.Suspension pin motor 55 is stepper motor.The power output of suspension pin motor
Axle 551 is provided with clamping joint 552.Clamping joint 552 is regular prism shape.The power output shaft of clamping joint 552 and suspension pin motor
551 is coaxial.The end face of suspension pin 54 is provided with blocked hole 541.Blocked hole 541 is square hole, blocked hole 541 and suspension pin 54
Coaxially.Clamping joint 552 is plugged in blocked hole 541 that the power output shaft 551 and suspension pin 54 of suspension pin motor is coaxial
It is joined together to realize passing power.It is additionally provided with suspension pin 54 along the circumferentially equally distributed light barrier 542 of suspension pin.It is in the light
Plate 542 has two pieces.Circumference of two pieces of light barriers 542 along suspension pin 54 is uniformly distributed.Light barrier 542 is provided with loophole 543.To penetrating
Formula optoelectronic switch 56 includes Switch main body 561 and speculum 562.Switch main body 561 and speculum 562 are separately fixed at suspension groove
On 53 both sides.The linearity of suspension pin 54 is when within setting range, when adjustment suspension pin to light barrier 542 is located at switch originally
