Abstract
A hub locking structure of an engineering vehicle axle belongs to a hub locking structure of an engineering vehicle axle. The locking structure comprises a front axle supporting shaft, a nut, a locked spacer and a fastening bolt, wherein, external threads are formed on the end part of the axle supporting shaft; a longitudinal slot is formed on the outer-diameter thread part; the nut, the locked spacer and the fastening bolt are installed in sequence on the end part of the axle supporting shaft; the nut is cylindrical; a longitudinal slot is formed on the outer surface of the nut; two threaded through holes are formed on the end surfaces of the nut; the locked spacer is in the shape of a ring; 16 through holes are formed around the surface of the ring; and a convex clamping pin is arranged on the inner diameter part. The locking structure has the advantages that the locking structure can ensure the connection reliability between a hub assembly and an axle supporting shaft of the engineering vehicle; the installation is simple; the assembly and the disassembly are convenient; the labor intensity is reduced; the adjustment of locking moment is effectively improved; the design and structure of the nut and the locked spacer are simple; the fastening blot meets the Chinese standard; the processing is simple; and the cost is lower.
Description
Technical field
The utility model relates to a kind of limit locking mechanism of taking turns, particularly a kind of engineering truck vehicle bridge wheel limit locking mechanism.
Background technology
For most of engineering truck vehicle bridge, wheel limit assembly will carry out fastening lockedly with vehicle bridge overhang bracket axial region position, loses with vehicle bridge and is connected to prevent to take turns the limit assembly, thereby jeopardize traffic safety.For addressing this problem, must wheel limit assembly is locked securely on vehicle bridge.At present, automobile driving axle is had a kind of locking mechanism, the patent No. is 200520010050.4.This utility model adopts fluted nut, crosses the pin-and-hole of axle drive shaft during assembling on groove with lock pin, locks.Its weak point is that 10 flutings on the fluted nut require calibration accurate, and this has just increased the complexity of parts machining process, and manufacturing cost is higher.
The utility model content
The purpose of this utility model is to provide a kind of manufacturing accuracy rate low, and the process of processing technology is simple, the wheel limit locking mechanism of the engineering truck vehicle bridge of low cost of manufacture.
The technical solution of the utility model is as follows: this vehicle bridge wheel limit locking mechanism comprises propons bolster, nut, locked spacer and binding bolt, in vehicle bridge bolster end outside thread is arranged, at the outer-diameter threads place vertical fluting is arranged, nut, locked spacer and binding bolt are installed in proper order in the end of vehicle bridge bolster.
Described nut is cylindrical, and outside face has vertical fluting, and the through hole of two screw threads is arranged on the end face of nut.
Described locked spacer is circular, and the anchor ring border is provided with 16 through holes, and inner radius is provided with a protruding card base.
Beneficial effect: owing to adopted such scheme, this nut of taking turns the limit locking mechanism is a circular nut, at first it is screwed at vehicle bridge bolster end thread position during assembling by the moment scope of setting, bolster end thread outer radius has vertical fluting, locked spacer then is installed again, the anchor ring border of locked spacer is provided with 16 through holes, inner radius is provided with a protruding card base, this card base is inlaid in the fluting of bolster end, while is rotating nut in guaranteeing the moment scope of setting, make two place's tapped bore on the nut end face align corresponding through hole on the locked spacer nearby, then 2 binding bolts are aligned with upper screwed hole respectively and screw and put in place, binding bolt is a six-sided head head eye bolt, uses steel wire to pass the aperture of binding bolt head, two binding bolts are together in series, and the coiled eight shape fixes, and it is low to make accuracy rate, and the process of processing technology is simple, low cost of manufacture has reached the purpose of this utility model.Advantage: this locking mechanism can guarantee to take turns bonded assembly reliability between limit assembly and the vehicle bridge bolster on the engineering truck vehicle bridge, and mounting process is simple, is convenient to assembly and disassembly, has reduced labour intensity, has improved the adjustment for screw-down torque effectively; While, binding bolt was selected the GB part for use owing to nut, locking plate project organization are simple, and therefore processing is simple, and cost is lower.

The specific embodiment
Embodiment 1: this vehicle bridge wheel limit locking mechanism comprises propons bolster, nut, locked spacer and binding bolt, there is outer-diameter threads vertical fluting to be arranged in propons bolster end, nut, locked spacer and binding bolt is installed in proper order in the end of preceding bridge bearing at the outer-diameter threads place.
Described nut is cylindrical, and outside face has vertical fluting, and the through hole of two screw threads is arranged on the end face of nut.
Described locked spacer is circular, and the anchor ring border is provided with 16 through holes, and inner radius is provided with a protruding card base.
This locking mechanism includes vehicle bridge bolster 1, nut 2, locking plate 3 and binding bolt 4.Nut 2 is a circular nut, is provided with two tapped through holees above, is evenly equipped with 4 flutings on the external diameter, and locking plate 3 cylindrical ring-types are evenly equipped with 16 through hole on the anchor ring, and inner radius is provided with a protruding card base.At first it is screwed at propons bolster 1 end thread position during assembling by the moment scope of setting, bolster 1 end thread outer radius is provided with one and vertically slots, locking plate 3 then is installed again, and the card base of projection is inlaid in the fluting of bolster 1 end, while is rotating nut 2 in guaranteeing the moment scope of setting, make two place's tapped bore on nut 2 end faces align corresponding through hole on the locking plate 3 nearby, then two binding bolts 4 are aligned with upper screwed hole respectively and screw and put in place, what binding bolt 4 adopted is state's tender six-sided head head eye bolt, pass the aperture of binding bolt 4 heads at last with the steel wire of corresponding specification, two binding bolts 4 are together in series, and the coiled figure of eight fixes, and realizes thus the locking between wheel limit assembly and the vehicle bridge bolster 1.
Claims (3)
