One drive unit that drives described baffle plate to move outside the axle axis bearing of trend, this drive unit is arranged between baffle plate and axle shaft end.
Thus, rely on locomotive wheel to design distinctive technology groove, design clamping close device and the assembling of hub for vehicle wheel technology groove.Drive unit is as power source, rely on pull bar and baffle plate accurately to be delivered on clamping close device by power, realize the wheel field-strip, because wheel hub is near than wheel rim apart from the axletree distance, therefore can guarantee preferably when moving back wheel that the force direction that is subject to that moves back the wheel stress point is parallel to the axletree axial line, while moving back wheel, wheel remains vertical with axletree, thereby realize moving back like a cork fast wheel, avoided the damage to bearing simultaneously.Installation process of the present invention is without special detection tool, relies on design accuracy to complete precise positioning, with than slight drag safety, move back and draw off wheel fast.
Be below the technical scheme of further improvement of the present invention:
Further, in order to facilitate drive unit, apply better active force, on described axle shaft end, cover plate is housed, described drive unit is arranged between baffle plate and cover plate.
As a kind of concrete version, described clamping close device comprises polylith Kazakhstan arc piece, and each is breathed out arc piece inboard and has the projection coordinated with locomotive wheel wheel hub technology groove, thus, polylith is breathed out to the arc piece and splice whole as clamping close device ringwise.Further, described clamping close device is that two semicircles to dress are breathed out the arc piece.
Described drive unit is a hydraulic cylinder, and an end of the piston rod of this hydraulic cylinder is close to axle shaft end, and this hydraulic cylinder body is close to described block.When axle shaft end is provided with cover plate, an end of the piston rod of this hydraulic cylinder is close on the cover board.
Described drive unit is a hydraulic cylinder, and an end of the piston rod of this hydraulic cylinder is close to described block, and this hydraulic cylinder body is close to described axle shaft end.When axle shaft end is provided with cover plate, this hydraulic cylinder body is close on the cover board.
In order to guide better the active force of drive unit, make it to pass to better on clamping close device, described hydraulic cylinder is hollow hydraulic cylinder, in this hollow hydraulic cylinder, is set with and draws bar, this draws bar through described block.Prevent that the axle end face pier from slightly reaching the axiality that guarantees hydraulic cylinder and axletree effect, and play position-limiting action to moving back the wheel process.
Preferably, the two ends of described pull bar have positioning step, guarantee that the depth of parallelism of breathing out between arc piece and baffle plate is better.
Preferably, on the arc piece of described Kazakhstan, have groove, be beneficial to effectively avoid pump nozzle.
Preferably, nut is equipped with in described outer end of drawing bar, described pull bar by nut locking on described block.
Compared with prior art, the invention has the beneficial effects as follows: Kazakhstan of the present invention arc architecture quality is light, quick for installation; The hydraulic trolley of using is installed on the specific support with roller, can realize fast moving.Servicing unit can effectively prevent that the axle end face pier from slightly reaching the dismounting position-limiting action.This equipment is compared the congenerous product, and it is simple in structure, cheap, be subject to place restriction less, takies the resources of production less, and personnel are shorter non-cutting time, and operating efficiency is higher, is particularly useful for harmonious series cab and Shenhua series cab.
Below in conjunction with drawings and Examples, the present invention is further elaborated.
