Abstract
The utility model relates to a front axle master pin locking structure with double locking pins. The front axle master pin locking structure comprises a front shaft, a master pin hole is arranged on the front shaft, a master pin is installed in the master pin hole, a pin locking hole is respectively arranged at the upper end and the lower end of the master pin hole, the two pin blocking holes are distributed on the left side and the right side of the master pin, two wedge-shaped locking pins are installed in the pin locking holes and locked through locking nuts, and the locking pin on the upper portion of the master pin hole is shorter than the locking pin on the lower portion of the master pin hole. According to the front shaft master pin locking structure with the double locking pins, the two pin locking holes are arranged at the upper end and the lower end of the master pin hole respectively and distributed on the left side and the right side of the front shaft, by means of the double pin locking structure, stressing points of the master pin are increased, and the stressing states of the master pin are improved, so that the relative position of the master pin can be fixed, four-wheel positioning parameters of the front shaft can be guaranteed, phenomena of braking shaking and braking deviation are reduced, and the front axle master pin locking structure is convenient to assemble and disassemble.
Description
Technical field:
The utility model belongs to automobile front axle stub locking technical field, is specifically related to a kind of propons stub locking mechanism of twin-lock pin.
Background technique:
Flourish along with the industry of China passenger vehicle, some external advanced technologies and product are constantly introduced and application.Aspect the locking of propons stub,, various trials have been carried out for improving locking Security, property easy to assembly, property easy to maintenance.Propons stub keying structure has dual mode at present: the one, adopt the liquid nitrogen assembling, and adopt interference fit between stub and the front axle.The 2nd, adopt the monolock pin structure, stub and front axle adopt Spielpassung.
The assembling of employing liquid nitrogen, the problem that the locking mode of stub and front axle interference fit exists is: 1) assembly process more complicated needs to make special assembly tooling; 2) assembly process need be used liquid nitrogen, wastes energy, and increases cost; 3) when maintenance and difficulty thereof, interference fit become one stub 2 and front axle, and stub is difficult to take off.
The problem that stub and the tight mode of front axle monolock lock exist is: 1) owing to the existence of front axle limiting stopper, wedge shape lock pin mounting hole can only be positioned at an end of front axle fist part during design, and stub is stressed bad; 2) in movement process, have only a lock pin to bear extruding force, lock pin damages easily; 3) in the using process, in case situation such as wearing and tearing, distortion appear in lock pin, phenomenons such as braking is shaken, braking deviation can appear.
The model utility content:
In sum, in order to overcome the deficiency of existing technology problem, the utility model provides a kind of propons stub locking mechanism of twin-lock pin; It is in the front-axle pivot hole up and down two ends a lockpin hole respectively is set, and two lockpin holes are distributed in the left and right sides of front axle, twin-lock pin structure; Increase the stub force bearing point, improve the stub stress, better the fixing relative position of stub; Guarantee the four wheel locating parameter of propons, reduce phenomenons such as braking is shaken, braking deviation, and easy installation and removal.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of propons stub locking mechanism of twin-lock pin; Comprise front axle, front axle is provided with kingpin bore, and stub is contained in the kingpin bore; Wherein: the two ends up and down of described kingpin bore respectively are provided with a lockpin hole; And two kingpin bores are distributed in the left and right sides of stub, and spring bolt is contained in the lockpin hole, and through locking nut locking.
Further, the spring bolt length on described kingpin bore top is less than the spring bolt of kingpin bore bottom.
Advance one, described two spring bolts are the wedge shape lock pin.
The beneficial effect of the utility model is:
1, the utility model be in the front-axle pivot hole up and down two ends a lockpin hole respectively is set, and two lockpin holes are distributed in the left and right sides of front axle, twin-lock pin structure; Increase the stub force bearing point; Improve the stub stress, the better fixing relative position of stub guarantees the four wheel locating parameter of propons; Reduce phenomenons such as braking is shaken, braking deviation, and easy installation and removal.
2, the utility model is simple in structure, easy to use, assembling is simple, easy to operate, does not need special setting tool, has the mistake proofing effect, even wherein some wedge shape lock pins damage, can not influence the function of whole propons.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of this practical stub;
Fig. 3 is the structural representation of the kingpin bore top spring bolt of the utility model;
Fig. 4 is the structural representation of the kingpin bore bottom spring bolt of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further to specify.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of propons stub locking mechanism of twin-lock pin comprises front axle 1; Front axle 1 is provided with kingpin bore, and stub 2 is contained in the kingpin bore, and the two ends up and down of kingpin bore respectively are provided with a lockpin hole; And two kingpin bores are distributed in the left and right sides of stub 2, and spring bolt is contained in the lockpin hole, and through locking nut locking; Two spring bolts are the wedge shape lock pin, and spring bolt 3 length on kingpin bore top are less than the spring bolt 4 of kingpin bore bottom.
During assembling, stub 2 is contained in the kingpin bore of front axle 1, again with short spring bolt 3 by going to the rear in the lockpin hole on the kingpin bore top of packing into, and at its threaded end assembling plain cushion, spring washer and nut, moment is tightened on request.Then with long spring bolt 4 back to front direction pack in the lockpin hole of kingpin bore bottom, at threaded end assembling plain cushion, spring washer and nut, moment is tightened on request.
Be noted that; The foregoing description is to the explanation of the utility model technological scheme and unrestricted; Other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to existing technology; As long as do not exceed the thinking and the scope of the utility model technological scheme, all should be included within the desired interest field of the utility model.
