Abstract
A kind of city railway vehicle pedal to pedal, it is characterized in that: include foot-driven lever, rotary shaft, left and right mounting seat, torsion spring, foot-driven lever is fixing on the rotary shaft by the installing plate at two ends, rotating shaft terminal stretches out installing plate and extends in the axle sleeve embedding left and right mounting seat, and left and right mounting seat is fixedly connected with the vehicle body by connecting plate above.By the pretightning force certain to torsion spring when the present invention installs, automatically reseting of foot-driven lever can be realized, and foot-driven lever can be made against car body, preventing the vibration in vehicle motor process, reduction takes up room, and meets vehicle gauge requirement, relatively low to the lower car body space requirement in vehicle operation, and due to the existence of torsion spring pretightning force, to the power-assisted effect getting on the bus certain, make driver and maintainer the most more convenient laborsaving from rail level.
Description
Technical field
The invention belongs to rail vehicle technical field, especially relate to the pedal to pedal that a kind of rail vehicle is got on or off the bus.
Background technology
For city railway vehicle, cloth cover distance rail level in floor, guest room is the highest, in the case of there is no platform,
Driver and maintainer get on the bus can be relatively difficult.The pedal to pedal being installed on lower car body can be with on assist driver and maintainer
Car, makes to get on the bus more convenient.
At present, rail vehicle pedal to pedal is to be fixed on car body by welding or screw, with car body relative to position is
Fix, non-movable, take up room when not in use bigger, be difficult to meet vehicle gauge requirement；Meanwhile, fixing pedal is only
Play the assosting effect of HOP ON-CHOP OFF, there is no assist function.
Summary of the invention
Have when it is an object of the invention to provide a kind of trampling assist function can automatically reset pedal to pedal, make driver
The most more convenient from rail level, laborsaving with maintainer；When not using, pedal is close to car body to pedal, and reduction takes up room, and meets car
Gauge requirement.
For achieving the above object, the present invention provides a kind of city railway vehicle pedal to pedal, it is characterised in that: include riding
Bar, rotary shaft, left and right mounting seat, torsion spring, foot-driven lever is fixing on the rotary shaft by the installing plate at two ends, and rotating shaft terminal stretches out
Installing plate also extends in the axle sleeve embedding left and right mounting seat, arranges torsion spring between left and right mounting seat and the installing plate of its homonymy, left
Right mounting seat is fixedly connected with the vehicle body by connecting plate above.
A backstop is connected by angle bar outside described installing plate.
Angle between two extreme positions of described foot-driven lever movement travel is 50 °-60 °.
The cantilever of described foot-driven lever is parallel with car body bottom surface near foot-driven lever part.
By the pretightning force certain to torsion spring when the present invention installs, it is possible to achieve automatically reseting of foot-driven lever, and foot can be made
Treadle, against car body, prevents the vibration in vehicle motor process, and reduction takes up room, and meets vehicle gauge requirement, to vehicle
Lower car body space requirement in running is relatively low, and due to the existence of torsion spring pretightning force, to certain power-assisted of getting on the bus
Effect, makes driver and maintainer the most more convenient laborsaving from rail level.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention；
Fig. 2 is the installation of the present invention and uses state diagram.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, the specific embodiment of the invention include foot-driven lever 4, rotary shaft 5, left and right mounting seat 11,8,
Torsion spring 7, foot-driven lever 4 is fixed in rotary shaft 5 by the installing plate 6 at two ends, and rotating shaft terminal stretches out installing plate and extends embedding
In the axle sleeve 9 of left and right mounting seat, axle sleeve 9 reduces the friction in rotary shaft rotary course with left and right mounting seat, left and right mounting seat
And arranging torsion spring 7 between the installing plate of its homonymy, the two ends of torsion spring 7 are by the installation on the installing plate at left and right mounting seat and two ends
Hole 12 is fixed, and left and right mounting seat is fixedly connected with the vehicle body with pilot nail 1 by connecting plate 2 above.
In order to reduce the impact of connecting plate 2 above installing plate in foot-driven lever reseting procedure 6 and mounting seat, outside installing plate 6
A backstop 3 is connected by angle bar 10.
The convenience got on the bus based on majority, the height of people's foot-up and the stride got on the bus, the two of foot-driven lever 4 movement travel
Angle a between individual extreme position is 50 °-60 °.
In order to ensure that foot-driven lever cantilever does not interferes with car body, the cantilever of foot-driven lever is near foot-driven lever part 14 and car body
13 bottom surfaces are parallel.
Claims (4)
