Embodiment
Below in conjunction with accompanying drawing and the embodiment that provides, the present invention is further illustrated.
As shown in Figure 1,3, a kind of rail vehicle braking clamp oil cylinder, there is cylinder body 3, described cylinder body 3 comprises front-bank rotor housing 3-1 and rear-bank rotor housing 3-2, and the axial attaching of front-bank rotor housing 3-1 and rear-bank rotor housing 3-2, described cylinder body 3 is built with piston 4, return piston 5, adjusting axle 6, guide rod 7, axle sleeve 8, elastic component 9 and spring pedestal 10.
Described piston 4 is sleeved on return piston 5, the step hole 5-1 of return piston 5 is stretched out in one end of described adjusting axle 6, the other end inserts in the axle sleeve hole 8-1 of axle sleeve 8, and be connected by non-self-lock-ing screw thread with the axle sleeve hole 8-1 of axle sleeve 8, described axle sleeve 8 is provided with annular boss 8-2, and the step 5-1-1 in the side of described annular boss 8-2 and the step hole 5-1 of return piston 5 offsets.
Described elastic component 9 is sleeved on axle sleeve 8, and the opposite side of one end of described elastic component 9 and the annular boss 8-2 of axle sleeve 8 offsets, and the other end and the spring pedestal 10 of described elastic component 9 offset.
One end of described guide rod 7 is inserted in the pilot hole 6-1 of adjusting axle 6, and the other end and rear-bank rotor housing 3-2 load, described spring pedestal 10 is fixed on rear-bank rotor housing 3-2 by the first screw 19.
Also have bayonet lock 14, described bayonet lock 14 is arranged in the pilot hole 6-1 of adjusting axle 6, and is sleeved on one end of guide rod 7, and the end of guide rod 7 one end is threaded with Cock screw 15.
As shown in Figure 1, 2, 3, also there is fixture block 11, described fixture block 11 is fixed on rear-bank rotor housing 3-2 by the second screw 20, and fixture block 11 has hexagon ring 11-1, the other end of described guide rod 7 has the protruding 7-1 of outer-hexagonal, described fixture block 11 is sleeved on the protruding 7-1 of outer-hexagonal of guide rod 7 the other end by hexagon ring 11-1, so just locking guide rod 7, preventing guide rod 7 when not needing to regulate because the factors such as vibrations rotate.
As shown in Figure 2, shown cylinder body 3 has the oil cylinder attachment hole 3-3 running through front-bank rotor housing 3-1 and rear-bank rotor housing 3-2, have oil cylinder attachment screw 3-4 in described attachment hole 3-3, front-bank rotor housing 3-1 and rear-bank rotor housing 3-2 is connected and is fixed in caliper mechanism 1 by described oil cylinder attachment screw 3-4.
The stepped shape end face of described front-bank rotor housing 3-1 and the end face axial attaching of rear-bank rotor housing 3-2, can certainly be, the stepped shape end face of described front-bank rotor housing 3-1 and the stepped shape end face axial attaching of rear-bank rotor housing 3-2, certainly can also be, the end face of described front-bank rotor housing 3-1 and the stepped shape end face axial attaching of rear-bank rotor housing 3-2.
As shown in Figure 1,3, be threaded by trapezoidal thread between the other end of described adjusting axle 6 and the axle sleeve hole 8-1 of axle sleeve 8.
As shown in Fig. 1,3,4, when the present invention uses, oil cylinder 2 is contained in caliper mechanism 1, and whole clamp is arranged on vehicle.
When a vehicle is started, the logical oil of oil cylinder 2, piston 4 moves right under the effect of oil pressure, drives return piston 5 to move right, because the step 5-1-1 in the step hole 5-1 of the annular boss 8-2 on axle sleeve 8 and return piston 5 offsets, axle sleeve 8 also moves right, make elastic component 9 forced compression on the one hand, on the other hand the adjusting axle 6 be threaded with axle sleeve 8 is also moved right, adjusting axle 6 no longer props up brake lining 22, brake lining 22 unclamps, and no longer limits the rotation of brake disc 21.Now elastic component 9 is compressive state.
When car brakeing, oil cylinder 2 is drained the oil, originally for the elastic component 9 of compressive state starts to alleviate, by discharging elastic force to annular boss 8-2, promote axle sleeve 8 to be moved to the left, the adjusting axle 6 be threaded with axle sleeve 8 is also moved to the left, and then adjusting axle 6 props up brake lining 22 and promotes brake lining 22 and is moved to the left, brake lining 22 is pressed close to brake disc 21 and is limited the rotation of brake disc 21, makes vehicle deceleration until stop.Annular boss 8-2 meanwhile on axle sleeve 8 promotes return piston 5 and is moved to the left, and drives piston 4 also to move to left together.
As Fig. 1, 2, shown in 3, when brake clamp is after using for a long time, brake lining 4 has wearing and tearing to a certain degree, now, even if the length that the adjusting axle 6 of oil cylinder 2 stretches out cylinder body 3 part reaches maximum, brake lining 4 and brake disc 21 also also have gap to exist, cannot normal brake application, when just needing to carry out manual tune to oil cylinder 2, at this moment only fixture block 11 need first be unloaded, then the protruding 7-1 of the outer-hexagonal of rotating guide-bar 7 the other end, because the end of guide rod 7 one end is threaded and bayonet lock 14 and pilot hole 6-1 corresponding matching with Cock screw 15, adjusting axle 6 is rotated together with guide rod 7, again because adjusting axle 6 is threaded with axle sleeve 8, now adjusting axle 6 becomes large with the assembling length of axle sleeve 8, when namely working, the length of stretching out cylinder body 3 part of adjusting axle 6 becomes large, and brake lining 4 and the gap of brake disc 21 obtain compensation, achieve gap adjustment.
