Abstract
A guiding device of an electronically controlled electric vehicle door comprises vehicle door systems (1) and a door head mechanism (7), wherein each vehicle door system (1) comprises left and right door leaves (1-1) and a shifting fork (1-2). The guiding device is characterized in that a door control unit (6) gives an instruction, then a motor drives variable diameter screws to rotate, and variable diameter nuts drive the shifting fork and the door leaves to carry out linear motion along the axis direction of the screws, thus quick opening and closing of the vehicle door are achieved through screwing of a minor-diameter nut-screw pair, and quick self-locking of the vehicle door is achieved through screwing of a major-diameter nut-screw pair. According to the guiding device, a locking device and a transmission device are combined into a whole; the minor-diameter part achieves quick opening and closing of the vehicle door; the closing speed is increased to 1.5-4.5s; and spherical guide wheels and guide rails form point contact. When the guide wheels roll, the frictional resistance is low and the frictional heat is still maintained at the original level, so that noises can not be increased. The screw-nut screw pairs achieve self-lubricating and the operating states are ensured without oiling, thus reducing the maintenance cost; and a more advanced, reasonable, safe and quick vehicle door system is formed.
Description
Technical field
The utility model relates to transmission, guiding and the mechanical locking device of rail traffic vehicles electricity powered car door, particularly just about the guiding device of the electricity powered car door of low friction reduction of heat.
Background technology
Rail vehicle electricity powered door is widely used in railway, city railway train.Mainly by door leaf, driving mechanism, transmission device, guiding device, locking device, door control unit (DCU) and Men Tou mechanism, formed.Driving mechanism is power source, and its drive transmission the rotation motion motion that is in line, and is delivered to door leaf and realizes the switch of door leaf.Guiding device limits the running orbit of door leaf.Locking device, after closing of the door, guarantee that car door cannot be opened in the situation that motor stops and nut is not applied to torsional interaction, guarantees traffic safety.Door control unit (DCU), the open and close situation of opposite house is implemented monitoring automatically and is controlled.Bogey, is carrying the total weight that driving, transmission, door leaf etc. install, and is affixed on car body.Screw-and-nut mechanism, guiding mechanism, mechanical locking device, be three piths of electricity powered car door composition, and existing electricity powered car door, for guaranteeing that closing of the door is firm, arranges separately a set of mechanical locking mechanism; In order to ensure closed safe, steady, low noise, normally (closing) speed of opening is controlled at 3-6s/ time, speed is lower than the speed of pneumatic door (1.5-4.5s/ time), there are to remarkable impact the upper and lower speed of passenger, dwell time, especially the subway train that start and stop are frequent, the volume of the flow of passengers is larger, slow, the independent sinuous defect of locking of its electricity powered car door ubiquity closing velocity.
Summary of the invention
In order to overcome slow, the independent sinuous defect of locking of existing electricity powered closing of the door speed, the purpose of this utility model is to provide a kind of guiding device of electricity powered car door, adopting directive wheel is spherical guiding mechanism, forms more advanced, reasonable, safe, opening/closing door of vehicle and a self-locking fast.
The technical solution of the utility model is achieved in the following ways: a kind of guiding device of electricity powered car door, comprises door device and Men Tou mechanism; Door device is comprised of two of left and right door leaf and shift fork; Men Tou mechanism is located at the top of door leaf, and driving mechanism, transmission device, guiding mechanism, locking device and door control unit are housed in Men Tou mechanism, and driving mechanism is comprised of motor and shaft coupling, and transmission device is comprised of combined threaded rod, nut and three supporting bases; It is characterized in that: described door control unit sends instruction, motor drive screw rotation, nut drives shift fork, the door leaf of guiding mechanism to do rectilinear motion along screw axis direction, and nut-screw pair screws realizes the rapidly opened and closed and self-locking of car door.
Described guiding mechanism is located at the top of door leaf, directive wheel and guide rail, consists of, and directive wheel rolls in the U-shaped groove of guide rail, and the upper lateral part of door leaf is connected with shift fork, and shift fork is link rod structure, by being arranged on an in-house loaded axle, is connected with combination nut.
Described directive wheel is ball-type directive wheel, is that point contacts with guide rail.
The utility model, ball-type directive wheel and guide rail form point and contacts, and during directive wheel rolling, little, the frictional heat of frictional resistance still keeps previous level, can not increase noise.Bolt and nut screw pair realizes self-lubricating, without oiling, guarantees running status, reduces maintenance cost, forms more advanced, reasonable, safe a, door device fast.
