Abstract
The utility model discloses a kind of fork truck front driving axle wheel limit structure, it comprises brake hub and rim bolt; The integral type brake hub that described brake hub is made up of brake wheel and wheel hub, this brake hub inner chamber is provided with counterbore locking groove; The rim bolt head both sides of described rim bolt are set to otch, and rim bolt head coordinates with counterbore locking groove.This fork truck front driving axle wheel limit structure has that cost of manufacture is low, assembly technology is simple, efficiency of assembling is high, the advantage of good product quality.
Description
Technical field
The utility model relates to fork truck front driving axle, particularly fork truck front driving axle wheel limit structure.
Background technology
At present, construction machinery industry fork truck front driving axle generally adopts tradition wheel limit structure, and this structure is primarily of brake wheel, wheel hub, bearing, oil sealing, rim bolt, rim nut, jam nut composition; During wheel limit assembled, wheel hub is loaded brake wheel with seam location, then the mounting hole on rim bolt press-in wheel hub, make the seam of rim bolt middle part snap in the position-limited trough of wheel hub outer end, make brake wheel by jam nut, wheel hub is linked to be entirety.There is following defect in brake wheel and the wheel hub fit system of this fork truck front driving axle wheel limit structure: one is split type owing to adopting, and each part needs independent one set of die, and two part faying faces all need higher requirement on machining accuracy, and manufacturing cost is high; Two is that assembly technology is loaded down with trivial details, and efficiency of assembling is low, and rim bolt structure is comparatively complicated, and manufacturing cost is high.
Summary of the invention
The purpose of this utility model is to provide that a kind of cost of manufacture is low, assembly technology is simple, efficiency of assembling is high, the fork truck front driving axle of good product quality wheel limit structure.
For realizing above object, the utility model fork truck front driving axle wheel limit structure comprises brake hub and rim bolt; The integral type brake hub that described brake hub is made up of brake wheel and wheel hub, this brake hub inner chamber is provided with counterbore locking groove; The rim bolt head both sides of described rim bolt are set to otch, and rim bolt head coordinates with counterbore locking groove.
The design of above-mentioned fork truck front driving axle wheel limit structure has following characteristics:
1, by brake wheel and wheel hub are made integral type, eliminate fitting surface, coordinate seam, can manufacturing cost be reduced, reduce overhours, improve element precision;
2, cancel jam nut, have changed the integral structure of rim bolt, increase by two otch at rim bolt head, increase counterbore locking groove at brake hub inner chamber, improve assembly technology, improve efficiency of assembling, reduce productive costs, substantially increase product design.
Adopt above-mentioned fork truck front driving axle to take turns limit structure, reduce cost, improve assembly technology, improve efficiency of assembling, improve element precision, substantially increase product design.
Accompanying drawing explanation
Fig. 1 is the main cross-sectional schematic of the utility model fork truck front driving axle wheel limit structure.
Fig. 2 is parts rim bolt schematic front view in Fig. 1.
Fig. 3 is that in Fig. 1, schematic diagram is looked at parts rim bolt mansion.
Reference numeral: brake hub 1, otch 2, rim bolt head 3, rim bolt 4, counterbore locking groove 5.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model fork truck front driving axle wheel limit structure is described in further detail.
The fork truck of the utility model shown in Fig. 1 ~ Fig. 3 front driving axle wheel limit structure comprises brake hub 1 and rim bolt 4; The integral type brake hub that described brake hub 1 is made up of brake wheel and wheel hub, this brake hub 1 inner chamber is provided with counterbore locking groove 5; Rim bolt head 3 both sides of described rim bolt 4 are set to otch 2, and rim bolt head 3 coordinates with counterbore locking groove 5.
Brake wheel and wheel hub are made integral type by said structure, form brake hub 1, can reduce manufacturing cost, reduce overhours, improve element precision; Brake hub 1 inner chamber increases counterbore locking groove 5, changes rim bolt 4 structure simultaneously, rim bolt head 3 is increased both sides otch 2, makes rim bolt 4 embed brake hub 1, prevent rim bolt 4 from rotating by counterbore locking groove 5.
The utility model fork truck front driving axle wheel limit structure can save jam nut, namely reduces number of parts, improves reduction productive costs; All-in-one-piece brake hub structure improves the precision of part simultaneously, decreases die cost and overhours, improves assembly technology, improves efficiency of assembling, improve the overall benefit of enterprise.
