Specific embodiment
Below in conjunction with attached drawing and the embodiment provided, the present invention is further illustrated.
As shown in Figure 1,3, a kind of rail vehicle braking clamp oil cylinder, has cylinder body 3, and the cylinder body 3 includes front-bank rotor housing
3-1 and rear-bank rotor housing 3-2, and front-bank rotor housing 3-1 and rear-bank rotor housing 3-2 axial direction attaching, the cylinder body 3 be provided with piston 4, return piston 5,
Adjustment axis 6, guide rod 7, axle sleeve 8, elastic component 9 and spring pedestal 10.
The piston 4 is sleeved on return piston 5, and the stepped hole 5-1 of return piston 5 is stretched out in one end of the adjustment axis 6,
The other end is inserted into the axle sleeve hole 8-1 of axle sleeve 8, and is connect with the axle sleeve hole 8-1 of axle sleeve 8 by non-self-lock-ing screw thread, described
Axle sleeve 8 is equipped with annular convex platform 8-2, the step 5- in the side of the annular convex platform 8-2 and the stepped hole 5-1 of return piston 5
1-1 offsets.
The elastic component 9 is sleeved on axle sleeve 8, and the annular convex platform 8-2's of one end and axle sleeve 8 of the elastic component 9 is another
Side offsets, and the other end and the spring pedestal 10 of the elastic component 9 offset.
In the pilot hole 6-1 of one end insertion adjustment axis 6 of the guide rod 7, the other end and rear-bank rotor housing 3-2 load, the bullet
Spring pedestal 10 is fixed on rear-bank rotor housing 3-2 by the first screw 19.
Also there is bayonet lock 14, the bayonet lock 14 is located in the pilot hole 6-1 of adjustment axis 6, and is sleeved on one end of guide rod 7,
The end of 7 one end of guide rod is threadedly coupled with holding screw 15.
As shown in Figure 1, 2, 3, also there is fixture block 11, the fixture block 11 is fixed on rear-bank rotor housing 3-2 by the second screw 20,
And there is hexagon ring 11-1 on fixture block 11, the other end of the guide rod 7 has outer-hexagonal protrusion 7-1, and the fixture block 11 passes through six
Corner apertures 11-1 is sleeved on the outer-hexagonal protrusion 7-1 of 7 other end of guide rod, can thus lock guide rod 7, and guide rod 7 is prevented to be not required to
Since the factors such as vibration rotate when being adjusted.
As shown in Fig. 2, there is the oil cylinder connecting hole 3-3 through front-bank rotor housing 3-1 and rear-bank rotor housing 3-2 on shown cylinder body 3, it is described
In connecting hole 3-3 there is oil cylinder attachment screw 3-4, the oil cylinder attachment screw 3-4 to be linked to be front-bank rotor housing 3-1 and rear-bank rotor housing 3-2
One is simultaneously fixed in caliper mechanism 1.
The step end face of the front-bank rotor housing 3-1 and the end face axial attaching of rear-bank rotor housing 3-2, naturally it is also possible to be, it is described
The step end face of front-bank rotor housing 3-1 and the step end face axial attaching of rear-bank rotor housing 3-2, certainly it is also possible that the front-bank rotor housing
The end face of 3-1 and the step end face axial attaching of rear-bank rotor housing 3-2.
As shown in Figure 1,3, pass through trapezoidal thread screw thread between the other end of the adjustment axis 6 and the axle sleeve hole 8-1 of axle sleeve 8
Connection.
As shown in Fig. 1,3,4, in use, oil cylinder 2 is in caliper mechanism 1, and entirely, clamp is mounted on vehicle to the present invention
On.
When a vehicle is started, the logical oil of oil cylinder 2, piston 4 move right under the action of oil pressure, drive return piston 5 to the right
Movement, since the annular convex platform 8-2 and step 5-1-1 in the stepped hole 5-1 of return piston 5 on axle sleeve 8 offsets, axle sleeve 8
It moves right, on the one hand makes 9 forced compression of elastic component, on the other hand make the adjustment axis 6 being threadedly coupled with axle sleeve 8 also to the right
Mobile, adjustment axis 6 no longer resists brake lining 22, and brake lining 22 unclamps, and no longer limits the rotation of brake disc 21.Elastic component 9 is pressure at this time
Contracting state.
When vehicle braking, oil cylinder 2 is drained the oil, and the elastic component 9 for being originally used for compressive state starts to alleviate, by annular convex platform
8-2 discharges elastic force, and axle sleeve 8 is pushed to be moved to the left, so that the adjustment axis 6 being threadedly coupled with axle sleeve 8 is also moved to the left, and then adjusts
Nodal axisn 6 resists brake lining 22 and brake lining 22 is pushed to be moved to the left, and brake lining 22 is close to brake disc 21 and limits the rotation of brake disc 21, makes
Vehicle deceleration is until stopping.The annular convex platform 8-2 on axle sleeve 8 pushes return piston 5 to be moved to the left at the same time, band piston 4
Also it moves to left together.
As shown in Figure 1, 2, 3, when brake clamp is after prolonged use, brake lining 4 has a degree of abrasion, this
When, even if the length that the adjustment axis 6 of oil cylinder 2 stretches out 3 part of cylinder body reaches maximum, also there are also gaps to deposit for brake lining 4 and brake disc 21
Can not normal brake application, it is necessary to when manually adjusting to oil cylinder 2, at this moment only need to first unload fixture block 11, then rotating guide-bar
The outer-hexagonal protrusion 7-1 of 7 other ends, due to the end of 7 one end of guide rod is threadedly coupled with holding screw 15 and bayonet lock 14 and guiding
Hole 6-1 corresponding matching so that adjustment axis 6 is rotated together with guide rod 7, and because adjustment axis 6 is threadedly coupled with axle sleeve 8, is adjusted at this time
Nodal axisn 6 and the assembly length of axle sleeve 8 become larger, that is, the length of 3 part of stretching cylinder body of adjustment axis 6 becomes larger when working, and brake lining 4 with
The gap of brake disc 21 is compensated, and realizes gap adjustment.
