Definitions

  • the preferred invention relates to a braking system and more particularly but not exclusively to an emergency braking system for use with vehicles running on rails such as are employed in mines or other areas where there are major problems in braking.
  • Another form of emergency braking system requires the use of a special rail which enable the emergency brake to grip an additional flanged extension and this is being developed during trials at the British National Coal Board's Ankwright Colliery near Chesterfield, Derbyshire (The Mining Engineer Vol. 141 No. 248 p.674).
  • Such a system is extremely expensive in that it will require the fitment of special rails not to mention the brake actuating assembly itself.
  • the present invention proposes a braking system which does not require the fitment of a special form of rail and which is adapted to operate in conjunction with existing rails.
  • the present invention consists in a braking system comprising a braked wheel adapted to provide a gripping contact laterally of the head of the rail.
  • the flanges of the braked wheel are so inclined as to provide a pair of small contact points on opposite sides of the rail head whereby the friction between the wheel and the rail is sufficient to allow transmission of torque to the wheel and thus turn the wheel as the vehicle to which the wheel is attached advances along the rail. A braking force can then be applied to the wheel to decelerate the vehicle. Due to the friction between the rail head and the wheel, the wheel does not slip on the rail when braking force is applied to the wheel and thus the braked wheel is able to decelerate the vehicle.
  • the braking system of this invention is not effected by - wet or oily rails which nullify the braking effect of pad type brake.
  • Fig. 1 is a sectional view through a rail showing the operation of a first embodiment in accordance with this invention
  • Fig. 2 is a sectional view through a rail showing the operation a second embodiment
  • Fig. 3 is a side elevation of a rail supported vehicle incorporating a braking system in accordance with the first BEST MODES OF CARRYING OUT THE INVENTION
  • Fig. 1 shows the main constructional features of a first embodiment wherein a wheel 2 contacts a rail 1 through wedge shaped wheel flanges 3.
  • the wedge angle is nominally 1 in 10 but may be varied according to the gradient of the rails and hence the friction required between the wheel 2 and rail 1.
  • Increased angular zones 4 are added to the outer wheel diameter for guiding the wheel 2 onto the rail 1 to effect braking.
  • the wheel 2 rotates on an axle 5 which is securely attached to a vehicle (not shown).
  • Braking pads 6 are used to transmit braking forces to the vehicle.
  • Braking pad 6 may contact the wheel directly as shown in Fig. 1 or may use an independent brake disc attached to the wheel 2.
  • the wheel 2 is suspended above the rail by, say, 20 mm.
  • the wheel is lowered onto the rail and the vehicle weight is transferred from the vehicle support wheels to the rail grip braking wheel 2.
  • a wheel or wheels 2 will normally be mounted adjacent to the vehicle support wheels (see Fig. 3).
  • Fig. 2 shows an alternative configuration where the force between the rail 1 and the wheel 2 is generated by springs 4a acting on thrust ring 2a.
  • the loading force on the sides of the head of rail 1 could also be applied by hydraulic or other means.
  • Braking force is transmitted to the vehicle (not shown) through brake pads 6.
  • the wheel rotates on and is secured to the vehicle by axle 5.
  • thrust ring 2a is spaced from the rail head against the bias of springs 4a.
  • springs 4a are released to drive thrust ring 2a into contact with the side of the rail head so gripping the rail 1.
  • Fig. 3 shows, a rail supported vehicle 10 supported on rail 1 by vehicle support wheels 11.
  • a rail grip braking wheel 2 in accordance with the first embodiment is mounted on the vehicle adjacent one of the support wheels 11 and a conventional pad brake 12 is mounted adjacent the other support wheel 11.
  • the pad brake 12 and rail grip brake wheel 2 operate as emergency brakes in the form of an emergency dump brake which dumps the vehicle 10 onto pad 12 and wheel 2 upon its actuation.
