Abstract
The utility model aims at providing an operating handle with a brake button of an electric car. The operating handle solves the existing problem that when the traditional electric car parked on a slope road is restarted, traffic accidents easily occur. The operating handle comprises a reversing operating handle, a velocity operating handle and an electromagnetic valve, wherein the reversing operating handle and the velocity operating handle are assembled on a control panel, and the electromagnetic valve is connected with a brake device through a pipeline. The operating handle is characterized in that a microswitch is arranged in a hole cavity of the upper end of the velocity operating handle; a movable button end of the microswitch is in contact with the brake button by using a linkage rod in a transverse hole cavity of the velocity operating handle, wherein the brake button is tightened by a restoring spring; and a terminal of the microswitch is connected with the electromagnetic valve through a lead wire in a vertical hole cavity of the velocity operating handle. The operating handle has compact structure, is reasonable in design and simple in operation and puts an end to automobile sliding phenomenon easily occurring in the process of parking on the slope, thereby the safety and reliability of automobile driving are greatly increased.
Description
Technical field
The utility model relates to the operating handle that a kind of rail, light rail electrical car are used, and particularly a kind of alternating current dynamo that is exclusively used in drives preventing to go on sloping road, to stop and occurring slipping the electric car operating handle of belt brake button of car phenomenon when opening car again of electric car.
Background technology
At present; China's tramway train, light rail electrical car adopt the DC machine chopper speed regulating device mostly; Usually adopt reversing contactor to come reversing rotation of motors, through the direction of current of the control of the change-over swith in traction circuit DC machine armature loop, to realize traction and braking.When motor need slow down, change-over swith or braking contactor in the control traction circuit carried out resistance braking or regenerative brake.Operating handle mainly comprises switch operation handle and speed operation handle two parts.The switch operation handle is used to change the travel direction of electric car; The speed operation handle is used for controlling traction, braking contactor and sends the speed that control signal changes electric car to chopper speed regulating device, and has the braking function when stopping.But there is not braking action opening car process medium velocity operating handle.When electric car went on planar tracks, existing operating handle can satisfy operating needs fully.But, need electric car on sloping roads such as the road of the high and low fluctuating of being everlasting or overpass, to stop and open car again along with development of urban rail traffic.Especially now the electric car that has adopts the ac motor speed control by variable frequency device; On sloping road, stop when opening car again; Electric car speed operation handle from braking mode through neutral (sliding state) when transferring traction state to; Because the ac motor speed control by variable frequency device can not be controlled the direction of current of armature loop as the DC machine chopper speed regulating device, existing electric car speed operation handle during brake off, does not but have brake function in start-up course; In case, slide car phenomenon very easily occurs so electric car starts on the slope.If electric car does not go in dedicated track, and mix row with city bus, occurrence of traffic accident is unfavorable for the development of track traffic easily.
The utility model content
The purpose of the utility model provides a kind of electric car operating handle that alternating current dynamo drives the belt brake button of electric car that is exclusively used in; Solved on the sloping road that existing electric car exists and stopped, opened the problem that appearance of vehicle is prone to occurrence of traffic accident; Its compact conformation; Reasonable in design, simple to operate, stop the slope and opened the slide car phenomenon that occurs easily in the car process; Improved the safe reliability of vehicle ' greatly.
The technical scheme that the utility model adopted is: the electric car operating handle of this belt brake button comprises switch operation handle, the speed operation handle that is assembled on the control panel and passes through the electromagnetic valve that pipeline connects brake gear; It is characterized in that: in the vestibule of the upper end of said speed operation handle, micro-switch is set; The active button end of micro-switch utilizes the gangbar in the lateral bore of speed operation handle to contact with the brake button of retracing spring tensioner, and the terminals of micro-switch connect electromagnetic valve through the lead in the vertical vestibule of speed operation handle.
Said electromagnetic valve is communicated with brake shoe or brake disc in the pneumatically operated brake through pipeline.
Said electromagnetic valve is communicated with brake shoe or brake disc in the brake gear that surges through pipeline.
Said electromagnetic valve is communicated with brake shoe or brake disc in the mechanical braking device through pipeline.
Advantage and the good effect that the utlity model has are: because the utility model is to be exclusively used in alternating current dynamo to drive electric car; In start-up course, during brake off, there is not brake function to carry out design-calculated, to existing electric car speed operation handle although it is provided with a micro-switch in the vestibule of the upper end of speed operation handle; But; But can through with the micro-switch control electromagnetic valve of brake button interlock, utilize solenoid control to carry out pneumatic, hydraulic pressure or mechanical brake, so even open car after stopping on the slope through pipeline bonded assembly brake gear; Can not slip the car phenomenon yet, improve the reliability of vehicle ' greatly.Its reason is exactly: owing to be provided with the micro-switch that the brake button drives in the upper end of speed operation handle, when opening car, handle in the speed operation handle brake off, can press the brake button simultaneously; Synchro control and electromagnetic valve bonded assembly brake gear brake, and make electric car from braking mode, through sliding state up to traction state; Releasing of brake button again, electric car can normally move, and just can not slip the car phenomenon this moment; So its reasonable in design; Though simple, very practical, be convenient to operation again.Therefore, solved on the sloping road that existing electric car exists and stopped, open the problem that appearance of vehicle is prone to occurrence of traffic accident, stopped the slope and opened the slide car phenomenon that occurs easily in the car process.
Description of drawings
