Germany Patent document DE 19702953 discloses a kind of magnesium material with corrosion-resistant coating.Corrosion-resistant coating is an alloy.
Germany Patent document DE 19749078 discloses a kind of setting that is used to prevent steel-magnesium contact corrosion.In a mesosphere that has an insulation between by steel and another parts of being made up of magnesium alloy, it will separate each other on two parts electrochemistry.The mesosphere is made up of the metallic aluminium that contains 98% aluminium at least.
German laid-open document DE 19813641 disclose a kind of can hydraulic operated isolation mounting.This isolation mounting is made up of the pressure shell of an aluminium or its alloy basically, and wherein, this pressure shell holds the guide sleeve of steel and is fixed on the gearbox case by magnesium or its alloy composition in annular pressure chamber.Because the corrosion potentiality of steel, aluminium and magnesium are different, when adding electrolytic solution, constitute corrosion factor, wherein, electronegative parts are preferentially corroded.For preventing this corrosion, a device that prevents contact corrosion is set in the contact area between pressure shell guide sleeve and gearbox case.Gearbox case utilizes tin coating to cover for this reason.The tin layer applies by the spray metallization technology.
Summary of the invention
The objective of the invention is to, a kind of operation equipment that is used for the automobile variable speed gear-box is provided, utilize this device to prevent locking or fixing.
The present invention includes a kind of operation equipment that is used for the automobile variable speed gear-box with at least one speed change lever.Speed change lever constitutes bearing hole, and speed change lever is rotatably mounted on the shaft element by this bearing hole.Speed change lever is installed on the frame member with hole by shaft element.Have at least one parts between shaft element and the speed change lever, its prevent contact corrosion and guarantee shaft element and speed change lever between turnability.Parts preferably constitute as axle sleeve and are pressed in the bearing hole of speed change lever.Axle sleeve is made up of plastics.Preferably consider the material of wear-resistant and low friction as plastics, as polyamide (PA) or polytetrafluoroethylene (PTFE), because these materials provide desired endurance.Therefore axle sleeve constitutes the plastic sliding bearing between speed change lever and the shaft element.
Shaft element can constitute the whole pivot pin that is pressed in the frame member.Pivot pin is formed from steel with frame member and is made by aluminium or aluminum alloy.Rotatable speed change lever separately of installing on the free end of pivot pin.As already mentioned above, turnability is guaranteed by plastic sliding bearing.
In another kind of formation of the present invention, shaft element is made up of two pivot pins that are pressed in the frame member.Turn the installation speed change lever by plastic bearing on the free end of each pivot pin.The axial upper support of each speed change lever utilization band platform axle sleeve.Parts constitute between shaft element and speed change lever like this, and speed change lever and frame member are kept at a distance.
Description of drawings
Other features of the present invention, purpose and advantage are from the following detailed description of the preferred embodiment for the present invention, but it is not so limited and consults accompanying drawing.Identical parts have identical reference numeral and part repetition of explanation not in this regard in principle.Wherein:
Fig. 1 is illustrated in first scheme of fixing at least one speed change lever on the frame member;
Fig. 2 is illustrated in the alternative plan of fixing at least one speed change lever on the frame member.
Embodiment
Fig. 1 illustrates at least one speed change lever 2a, 2b and is fixed on schematic representation on the frame member 5.Frame member 5 has bearing hole 4.In addition, each speed change lever 2a, 2b have the hole 7 that shaft element 6 can pass.Parts 10 are installed in the hole 7 of speed change lever 2a or 2b separately, and it guarantees at least one speed change lever 2a or the 2b turnability with respect to frame member 5.Parts 10 constitute as axle sleeve and are pressed in the hole 7 of at least one speed change lever 2a or 2b.Therefore axle sleeve or parts 10 are the plastic sliding bearings of at least one speed change lever 2a or 2b, thereby the axle 8 that this at least one speed change lever 2a or 2b can distribute around the hole 4 by frame member 5 rotates.The turnability of at least one speed change lever 2a or 2b threaded shaft element 6 is guaranteed, and is made up of two pivot pin 6a and 6b in this shaft element mode of execution shown here.These pivot pins 6a and 6b are pressed in the hole 4 of frame member 5.For speed change lever 2a or 2b are fixed on the direction of axle 8, each pivot pin 6a and 6b have band platform axle sleeve 12 on its free end.
Fig. 2 illustrates second mode of execution of the present invention, wherein shaft element 6 as a whole pivot pin constitute.Whole pivot pin is pressed in the hole 4 of frame member 5 equally.In at least one speed change lever 2a or 2b, constitute hole 7 equally, the inside pressing parts 10 or axle sleeve, it guarantees the turnability of speed change lever 2a and 2b threaded shaft element 6.In the mode of execution that Fig. 2 introduced, Axial Mounting Part is not installed on the shaft element 6.As depicted in figs. 1 and 2, parts 10 constitute like this, and each speed change lever 2a and 2b and frame member 5 are kept at a distance.Contact not producing between speed change lever 2a and 2b and the shaft element thus by parts 10 or axle sleeve, and speed change lever 2a, 2b do not contact with frame member 5.Eliminate thus and form plated item and therefore eliminate possible contact corrosion.
