Description

The bont that is used for power actuated vehicle
Technical field
The present invention relates to a kind of bont that is used for power actuated vehicle according to claim 1 preamble.
Background technology
DE101 23 491A1 disclose a kind of adjustable springs pillar for power actuated vehicle, this spring leg has helical spring damper element with one, this damper element is with a damping cylinder, one movably piston rod, two cotter seates and two ring-type cylinders, they define the epitrochoidal chamber of a variable-volume, wherein, one of these ring-type cylinders are movably in the axial direction and have one of these cotter seates.
Summary of the invention
The objective of the invention is to design a kind of device for power actuated vehicle or so-called bont, this device can make power actuated vehicle promote from a normal position and enter a raised position after the lifting.
According to the present invention, this purpose is that the feature by claim 1 realizes.Each dependent claims has comprised other favorable characteristics.
The present invention the main advantage that realizes be, come lifting vehicle by a jigger lifting piston that in the lifting cylinder of this spring leg, is directed.This present invention has been proposed especially, spring leg hole on top is located, is provided with a lifting cylinder that is equipped with compressed air interface at piston rod, in this lifting cylinder, be provided with a jigger lifting piston, this jigger lifting piston is arranged in and can moves axially to the normal position of an immigration on the piston rod and move axially the raised position that shifts out to, at this jigger lifting piston, this cotter seat is spatially around a fixed stop absorber from medial support for the cotter seat that is used for a helical spring top.
According to the present invention, jigger lifting piston is on the normal position is placed with internal backplane at lifting cylinder, and on by the raised position of pressurized air effect, can from lifting cylinder, shift out with an axial stroke, and remain on the spacing ring of lifting cylinder in the end of raised position.Because the jigger lifting piston in the lifting cylinder is air effect by compression, this jigger lifting piston move down and lifting vehicle to raised position.If pressurized air is discharged from once again, the weight of vehicle pushes back its normal position to jigger lifting piston again, and vehicle is in again on the position after the reduction.
In order to seal jigger lifting piston with respect to lifting cylinder, this jigger lifting piston be arranged to by the first outside seal ring with respect to the lifting cylinder sealing and by the second inner sealing ring with respect to piston rod packing.Between lifting cylinder and piston rod, formed a ring surface with annular space as the compression chamber that works.Sealing between jigger lifting piston and lifting cylinder can be arranged on the cylinder bottom and/or can be arranged on the piston wall laterally.
According to the present invention proposes, lifting cylinder and fixed stop absorber and cotter seat consist of parts in addition, and they are coupled to each other in the mode that the motion with jigger lifting piston arrives normal position and raised position.According to the present invention, can realize by this set of structural unit that in more favourable mode jigger lifting piston not only promotes support spring but also together promotes fixed stop absorber; And avoided the state of support spring after lifting, namely be fully pressed at raised position.In addition, the vehicle upper spring amount of deflection stroke of beating keeps size identical.
According to the invention allows for, cotter seat is embodied as form of sleeve, its upper end is supported on the bottom of jigger lifting piston, and has the axle collar (Ringbund) of a travelling backwards in reciprocal lower end, and helical spring end turn remains on this axle collar.This cotter seat Perfect Ring is around fixed stop absorber and form a compression chamber that is used for fixed stop absorber.
Description of drawings
The embodiments of the invention displaying at length describes in the accompanying drawings and following.
Among the figure:
Fig. 1 shows the view for the spring leg after the installation of the lifting means of vehicle or raising device,
Fig. 2 shows the cutaway view of the spring leg that is assembled together with raising device, and this raising device is comprised of a lifting cylinder, a jigger lifting piston, a cotter seat and a fixed stop absorber,
Fig. 3 shows the view at the entopic raising device of vehicle, and
Fig. 4 shows the view of the raising device of the raised position after vehicle promotes.
The specific embodiment
Spring leg 1 is arranged between the vehicle body and wheel carrier of vehicle, and has a piston rod that is directed in spring leg cylinder 45, and this piston rod is hinged on the vehicle body and with bottom 7 with a upper springs pillar hole 6 and is supported on wheel carrier or the wheel suspension.
At upper springs pillar hole 6 places, at piston rod 5 lifting cylinder 8 is installed, this lifting cylinder has an interface 9 that is used for input compressed-air.Be provided with a jigger lifting piston 10 in the lifting cylinder 8, this jigger lifting piston can move axially to normal position I (Fig. 3) and the raised position II (Fig. 4) after shifting out after the immigration in lifting cylinder 8 on the piston rod 5.The stroke that forms between two position I and position II indicates with H and further illustrates between Fig. 3 and Fig. 4.
On jigger lifting piston 10, the cotter seat on this top is spatially around a fixed stop absorber 14 from medial support for the cotter seat 11 on the top of coil spring 12.
At normal position I, jigger lifting piston 10 is placed with on the internal backplane 15 of lifting cylinder 8, and has the stroke H that shifts out from lifting cylinder 8 at the raised position II by the pressurized air effect.
In the end of the raised position II of the jigger lifting piston 10 that shifts out from lifting cylinder 8, jigger lifting piston 10 is supported on the spacing ring 17 with lower edge 16, and this spacing ring remains in the lifting cylinder 8 on circumference medially.
Realize jigger lifting piston 10 with respect to the sealing of lifting cylinder 8 and piston rod 5 by seal ring 18 and 19, wherein seal ring 18 is arranged between jigger lifting piston 10 and the lifting cylinder 8, and another seal ring 19 is arranged between jigger lifting piston 10 and the piston rod 5.Seal ring 18 as shown in Figure 2 can be arranged on piston top 20 or the piston wall 21, as shown in Figure 3, Figure 4.The cotter seat 11 on top and fixed stop absorber 14 are connected into parts with lifting cylinder 8, wherein power remains on the internal backplane of jigger lifting piston 10 cotter seat 11 ordinatedly by the spring of coil spring 12 is pre-tensioner, and fixed stop absorber 14 is to be fixed on the internal backplane of jigger lifting piston 10.
By this connection, make these three members 10,11 and 14 from normal position I to raised position 2 and the associated movement of Return-ing direction become possibility.With the downward movement of jigger lifting piston 10, beating in the state of lifting lower spring amount of deflection keeps size identical by fixed stop absorber 14.
Cotter seat 11 is implemented as form of sleeve, and extends to the free end of fixed stop absorber 14 from the internal backplane of jigger lifting piston 10.The upper end of cotter seat 11 is supported on the internal backplane of jigger lifting piston 10, and the free end below reverse is provided with an axle collar 21, is used for the end turn 22 of support helix spring 12.The axle collar 21 travelling backwards, thus realization is used for the angled reception of helical spring end turn 22.
