Abstract
The invention provides a guiding device of an electronically controlled electric vehicle door. The system 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 improved to 1.5-4.5s; 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 added; 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 present invention 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 formed by door leaf, driving mechanism, transmission device, guiding device, locking device, door control unit (DCU) and door head mechanism.Driving mechanism is power source, and its drive transmission the rotation motion motion that is in line, and is delivered to the switch that door leaf is realized door leaf.Guiding device limits the running orbit of door leaf.Locking device will be guaranteed to stop and nut not being applied under the situation of torsional interaction at motor behind closing of the door, and car door can't be opened, and guarantees traffic safety.Door control unit (DCU), the open and close situation of opposite house are implemented monitoring automatically and control.Bogey is carrying the total weight that driving, transmission, door leaf etc. install, and is affixed on the car body.Screw-and-nut mechanism, guiding mechanism, mechanical locking device are three piths that the electricity powered car door is formed, and existing electricity powered car door for guaranteeing that closing of the door is firm, arranges a cover mechanical locking mechanism separately; In order to ensure closed safe, steady, low noise, normally opening (closing) speed control at 3-6s/ time, speed is lower than the speed (1.5-4.5s/ time) of pneumatic door, there are appreciable impact speed, dwell time up and down to the passenger, especially the subway train that start and stop are frequent, the volume of the flow of passengers is bigger, slow, the independent sinuous defective of locking of its electricity powered car door ubiquity closing velocity.
Summary of the invention
In order to overcome slow, the independent sinuous defective of locking of existing electricity powered closing of the door speed, the object of the present invention 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.
Technical scheme of the present invention realizes in the following manner: a kind of guiding device of electricity powered car door comprises door device and door head mechanism; Door device by about two door leafs and shift fork form; The door head mechanism is located at the top of door leaf, on the door head mechanism driving mechanism, transmission device, guiding mechanism, locking device and door control unit is housed, and driving mechanism is made up of motor and shaft coupling, and transmission device is made up of combined threaded rod, nut and three supporting bases; It is characterized in that: described door control unit sends instruction, the rotation of motor-driven screw rod, and nut drives shift fork, the door leaf of guiding mechanism and does rectilinear motion along the 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, is made up of directive wheel and guide rail, 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, is connected with combination nut by the loaded axle that is installed in the head mechanism.
Described directive wheel is the ball-type directive wheel, is that point contacts with guide rail.
The present invention, ball-type directive wheel and guide rail form point and contacts, and little, the frictional heat of frictional resistance still keeps previous level during the directive wheel rolling, can not increase noise.The bolt and nut screw pair realizes self-lubricating need not oiling, guarantees running status, reduces maintenance cost, forms more advanced, reasonable, safe a, door device fast.
