Embodiment 5
The present embodiment is the particular content of hydraulically locking device working principle.
Hydraulically locking device working principle: below according to state I (Fig. 2 a) → state I I(Fig. 2 b) → state I II(Fig. 2 c) →
State I V(Fig. 2 d) → state I (Fig. 2 a) action process and state V(Fig. 3 e) → state VI(Fig. 3 f) and action process retouch
State the working principle of hydraulically locking device of the present invention.
Wherein, oil circuit direction A → B of check valve is closed circuit, and B → A is access, other oil circuit directions are as shown by arrows.
State I (Fig. 2 a) → state I I(Fig. 2 b): vehicle slips fashionable braking, the compression of tripping spring group
When as boundary member in use, reversal valve is located at retarder location by default.After reversal valve power-off, no current in coil
Pass through.At this point, the distance between two braking rail working faces are (1370 ± 3) mm, it is greater than vehicle interior side distance (1353 ± 3) mm.
When vehicle slips fashionable, inward-facing extruding braking rail on the inside of wheel, by support arm compression tripping spring group, tripping spring group passes through
Pressure is transmitted to the piston in oil cylinder by piston rod.But check valve at this time is in close state, and hydraulic oil cannot flow, piston
Immovable, then tripping spring group is compressed, and the thrust of tripping spring group is extruding force of the braking rail to wheel.Due to braking
The rigidity of groups of springs is very high, and the powerful frictional force between braking rail and wheel can do braking work to driving is slipped, and forces vehicle
Parking.As long as not giving reversal valve power transmission, system is in retarder location always, makes to slip row vehicle brake parking at any time.
State I I(Fig. 2 b) → state I II(Fig. 2 c): alleviation when vehicle involves, tripping spring group reset, reset spring pressure
Contracting
When needing to involve on vehicle, reversal valve is converted to alleviating position, check valve is in the conductive state at this time.Oil communication
Afterwards, piston can move in cylinder body, and since the wheel side of tripping spring group is limited by wheel, tripping spring group is stretched inwardly
Exhibition, compression reseting spring.When tripping spring group extends to precompressed length, brake force disappears, and at this moment acts in braking rail
Pressure there was only the elastic force of reset spring, since the rigidity of reset spring is very low, only the 5%~20% of tripping spring group, to leading
The resistance very little of operation out.
During vehicle involves, as long as first bogie of vehicle has passed through boundary member, due to the work of hydraulically locking device
With the distance between two braking rail working faces of boundary member meeting automatic blocking is equal to wheel inner distance in (1353 ± 3) mm()
State, the wheel passed through again later, frictional force can be smaller, does not influence on operation is involved substantially.Since reversal valve is in slow
Xie Wei, be used cooperatively check valve, hydraulic oil also can only one-way flow, to lock the compressive state of reset spring.
State I II(Fig. 2 c) → state I V(Fig. 2 d) → state I (Fig. 2 a): vehicle resets after moving out, and reset spring resets
After involving operation, when needing boundary member restoring retarder location, brake activation button converts reversal valve to braking
Position unlocks hydraulically locking device.Due to there is no wheel to be clipped on boundary member, two braking rails under action of reset spring, rapidly by
(1353 ± 3) mm of locking position is transformed into (1370 ± 3) mm of retarder location, completes homing action.
State V(Fig. 3 e) → state VI(Fig. 3 f): deceleration when vehicle passes through
When as retarder in use, under reversal valve default conditions be located at alleviating position, tripping spring group is pre- with reset spring
Length is pressed, check valve is in the conductive state, and piston can move in cylinder body.When vehicle passes through boundary member, vehicle passes through braking
Rail and tripping spring group compression reseting spring (reset spring resistance is less than tripping spring group resistance), and pushed and lived by piston rod
Plug movement, the pressure at this moment acted in braking rail is the elastic force of reset spring, and resistance is smaller, vehicle braking will not be made to stop
Only.
Check valve, (electromagnetism) reversal valve are commercially available part, which is the prior art of fields, therefore does not explain in detail
Its internal mechanism is stated, as long as being able to achieve the purpose of the present invention.
Although a sealing ring 45 is only marked in appended drawing reference in Fig. 1, in actual use to guarantee leakproofness, according to need
It wants and sealing ring is set between corresponding part (present invention is mainly between piston 44 and cylinder body 32, end cap I 31, end cap II
Between 33 and cylinder body 32 etc.) belong to ordinary skill in the art means, it is not described in detail in specific structure.
In Fig. 2, Fig. 3, the compression distance of reset spring and tripping spring group is only to illustrate, and purpose is only that signal spring
Compressed action, decrement in actual use may be different from diagram.
