Adopt the oleo-pneumatic suspension system can realize the flexible latch functions of engineering truck resilient suspension, the elastic element of oleo-pneumatic suspension is a hydro-pneumatic spring.Hydro-pneumatic spring mainly is made up of working cylinder, piston, air chamber etc., and as elastic element, fluid plays transfer function power and damped vibration then as intermediate medium with compressible gas for it; By the be connected oil circuit of cut-out oil cylinder with air chamber and other Hydraulic Elements, utilize the less characteristics of fluid compressibi1ity, realize the compliance in suspension locking.Advantages such as it is little to adopt the oleo-pneumatic suspension system to have quality, and the life-span is long, and is easy to operate, and the elastic atresia is simple, but hydro-pneumatic spring needs a cover guide piece and an air machinery, sealing part is many, and gas leakage costs an arm and a leg easily.Can't adopt on the current automobile widely used steel spring as suspension system, inconvenient maintenance.
Summary of the invention
Technical problem to be solved in the utility model is to overcome and must adopts the oleo-pneumatic suspension system to realize the restriction that engineering truck resilient suspension system flexibility latch functions is brought, provide that a kind of cost is low, the life-span long, the flexible lockable mechanism of resilient suspension simple in structure, easy to maintenance, can form suspension system in conjunction with multiple elastic element, realize the flexible locking of a High Speed Engineering Vehicle suspension system.
The technical solution of the utility model is achieved in that the utility model comprises the conversion oil cylinder, shift fork, screw nipple and pull rope mechanism, cylinder support is fixed on the vehicle frame, cylinder support links to each other with the fixed end of conversion oil cylinder, the movable end of conversion oil cylinder is connected with shift fork, one end of shift fork is installed on the vehicle frame by declutch shift shaft, the other end of shift fork links to each other with screw nipple, screw nipple is connected with pull rope mechanism, pull rope mechanism is connected with the stay cord seat by the race of leading sheave, leading sheave is installed on the vehicle frame by sheave shaft, and the retaining rope support is installed on sheave shaft.
Screw nipple is connected by screw thread pair with pull rope mechanism.
Described retaining rope support is a circular arc.
The utility model on the basis of vehicle frame resilient suspension system, increase by one the cover flexible lockable mechanism, provide conversion power with vehicle self hydraulic efficiency pressure system, with chain stretching device as locking component.The critical component of lockable mechanism mainly comprises conversion oil cylinder, shift fork, screw nipple and pull rope mechanism.Engineering truck is when running at high speed, and lockable mechanism is in released state, and resilient suspension system has maximum free displacement, and damping of vibrations gives full play to when being beneficial to run at high speed.When engineering truck need be transformed into the low speed operating condition, the conversion oil cylinder is released forward, the rotation of promotion shift fork, shift fork drives screw nipple and pull rope mechanism action, pull rope mechanism is upwards mentioned steel spring, conversion oil cylinder hydraulic oil circuit locking, and this moment, the free displacement of resilient suspension system was restricted, realize the flexible locking of resilient suspension, be beneficial to the low speed job requirements.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described in detail.
Shown in Fig. 1,2,3, the utility model increases the flexible lockable mechanism of a cover on the basis of vehicle frame resilient suspension system.Resilient suspension system mainly is made up of steel spring 14, shock absorber 5, rubber block 17 and buffering boss 18.Rubber block 17 is installed on the steel spring 14, and buffering boss 18 is positioned at the top of rubber block 17, is installed on the vehicle frame 1.Engineering truck is when running at high speed, and lockable mechanism is in released state, and steel spring 14 has maximum free displacement, and damping of vibrations gives full play to when being beneficial to run at high speed.The critical component of lockable mechanism mainly comprises conversion oil cylinder 13, shift fork 9, screw nipple 6 and pull rope mechanism 2.Conversion oil cylinder 13 fixed ends are installed on the cylinder support 11 by bearing pin 12, and conversion oil cylinder 13 can rotate around bearing pin 12, and 11 of cylinder supports directly are welded on the vehicle frame 1.Sheave shaft 19 is installed on the vehicle frame 1, and shift fork 9 is a weldment, is installed on the vehicle frame 1 by declutch shift shaft 8, can rotate around declutch shift shaft 8.Shift fork 9 one ends link to each other by the movable end of bearing pin 10 with conversion oil cylinder 13, and the other end links to each other with screw nipple 6 by bearing pin 7.Screw nipple 6 and pull rope mechanism 2 are connected by screw thread pair, regulate the suitable usable length of pull rope mechanism 2 by screw thread pair when being convenient to install.Pull rope mechanism 2 is installed on the stay cord seat 15 by the race of leading sheave 4.Retaining rope support 3 is installed in the outside of leading sheave 4.Stay cord seat 15 directly is welded on the vehicle bridge 16.Vehicle bridge 16 two ends are equipped with wheel 20.
With reference to shown in Figure 4, leading sheave 4 is installed on the vehicle frame 1 by sheave shaft 19.For preventing that pull rope mechanism 2 from coming off, the retaining rope support 3 of circular arc is installed on sheave shaft 19.
Mechanism's state and course of action are as follows:
Engineering truck is when running at high speed, and lockable mechanism is in released state.Change oil cylinder 13 and be in retracted state this moment, and rubber block 17 is bigger with buffering boss 18 spacings, and steel spring 14 has maximum free displacement, can give full play to its damping of vibrations.
When engineering truck need switch to the low speed operating condition by high-speed travel state, hydraulic efficiency pressure system provides switching power, conversion oil cylinder 13 piston rods are released forward, promote shift fork 9 around declutch shift shaft 8 clickwises, drive screw nipple 6 and pull rope mechanism 2 actions by bearing pin 7, pull rope mechanism 2 is upwards mentioned steel spring 14 gradually.After oil cylinder 13 piston rods to be converted reached the position, action was finished, and lockable mechanism has switched to the flexible latch state.The hydraulic circuit locking, conversion oil cylinder 13 is in the range state, and rubber block 17 is less with buffering boss 18 spacings, and steel spring 14 free displacements are less.This moment, suspension system still had part elasticity, can play certain damping of vibrations, realized the flexible locking of resilient suspension, satisfied engineering truck low speed operation operating mode.
When engineering truck need switch to high-speed travel state by the low speed operating condition, then lockable mechanism switched to released state by blocking, and this moment, the action of mechanism's each several part was with above-mentioned opposite.
