Description
Technical field
The present invention relates to a kind of slide device that is used for the current colector of falling of electrically driven vehicles, described slide device is fixed with the sliding contact body that is provided with along the length of carriage by constituting with collector bow bonded assembly carriage on the carriage.
Background technology
The sliding contact body that is used for the current colector of electrically driven vehicles mainly is made of graphitec carbon, in order to improve its electric conductivity, graphitec carbon is added with other metal ingredient.Because graphitec carbon is resisted the intensity of effect of the violent mechanical strees that usually occurs in the air wire scope relatively poor, so sliding contact body is fixed on the part as the carriage of seat part.The seat part normally rectangle or trapezoidal.Carriage is all made by aluminium or zincing steel sheet together with seat spare.Under certain conditions, for example when transporting, cross-border railway when being transformed into another supply network and when frost, will between trolley and carriage, produce electric arc, and trolley and carriage are damaged, and also can make the mechanical strength of the sliding contact body in the part impaired thereupon.
DE 94 01 585.6U1 have disclosed a kind of wiping spare, and the outside of described wiping spare has certain thickness electrically insulating material, and this thickness has been guaranteed higher electric simulation strength." dielectric strength " notion mean make insulating material impaired and the forfeiture insulating power the electric field strength corresponding to material thickness.Insulating material is provided with the outside of present part or carriage.Adopt expensive metal spraying or plasma metallizing technology with electrically insulating material attached to the outside.Can also ceramic layer or plastic layer be fixed on the carriage by bonding.But practice shows, when wiping spare is subjected to violent mechanical force, wiping plate (sliding contact body), particularly the phenomenon of its strength reduction and fracture will appear in the insulating barrier in the critical range between wiping plate and coating under certain situation, or it is impaired and because of the impaired phenomenon that can cause occurring electric arc again of insulating barrier insulating barrier also can to occur in addition.Thereby sliding contact body (wiping plate) is not avoided the impaired protection of machinery.
Summary of the invention
The objective of the invention is to propose a kind of slide device that is used for the current colector of falling of electrically driven vehicles, described slide device is by constituting with collector bow bonded assembly carriage, be fixed with the sliding contact body that is provided with along carriage length on the carriage, wherein avoid sliding contact body to be subjected to mechanical damage, and avoided occurring on seat part or the carriage phenomenon of arcing.
Of the present inventionly relate to a kind of slide device, the current colector of falling that is used for electrically driven vehicles, described slide device is by constituting with collector bow bonded assembly carriage, on described carriage, be fixed with the sliding contact body that is provided with along the length of described carriage, the sidewall of described carriage, the lower area of described carriage and the side of described sliding contact body have lining, described lining has the lining that the described carriage of electrical insulation characteristics and described sliding contact body have the clamping sleeve structure, described lining profile coats to carriage and to the side of fixing the sliding contact body in the present part ordinatedly, described lining does not cover the scope of wiping face, and by being provided with in conjunction with the clamping action of the lining side to described carriage and described sliding contact body with coating.
The structure design of lining cooperates with the side profile of carriage and wiping plate, and both coat to the back.This side with lining and carriage and wiping plate profile closely is connected and has realized mechanical protection to the best of wiping plate, realizes electric disruptie strength simultaneously on whole carriage, and avoids electric arc to occur.
Lining of the present invention is the clamping sleeve structure, and this point is a significant benefit to the renewal to existing slide device, is convenient to lining along the clamping effect of the passing of carriage and sliding contact body and lining and will realize stable fixing in conjunction with its shape.The clamping auxiliary member that corresponding machinery preferably is set further improves the clamping effect.
According to further design of the present invention, lining is made of the material of electrical isolation substantially, wherein by selecting for use suitable material to add enhance mechanical strength.Particularly suitable such as polymeric materials such as polyamide, polyetherimide or polyethersulfones.
According to further design of the present invention, adopt composite material, the application of described composite material is considered that at first the lining in the sliding contact body scope will be subjected to the situation of king-sized mechanical strees.Therefore for example additional reinforcement or reinforcing material can be combined with lining, so that just in time in the sliding contact body scope, realize resisting the added strength of violent stress.Additional reinforcement or reinforcing material for example can be the suitable lamination coating relevant with poly-mer, for example carbon fiber.But the hardness that wherein is noted that the lining in the sliding contact body scope must not be greater than the hardness of sliding contact body material itself.
According to further design of the present invention, lining has the space, and described space particularly is arranged in the carriage scope, almost can avoid the arcing to air wire in described scope.It is adaptive that described space can realize that lining that profile cooperates and carriage and sliding contact body make up.
According to further design of the present invention, the side of described lining and carriage and/or sliding contact body is bonding.
According to another kind of design of the present invention, lining can be two yuan or multi-factor structure, also can be made of two vertical half parts.Therefore can take in the constructional feature of slide device and cylinder-packing is carried out adaptive adjustment according to this constructional feature.
