Abstract
The utility model relates to an anti-smashing device of a pin roll of a suspension arm, which comprises a suspension arm seat which is welded on two rear pillars of a carriage side plate assembly. The suspension arm corresponding to the suspension arm seat is welded on side pillars on two sides of a carriage rear door assembly; the suspension arm is connected with the suspension arm seat through the pin roll; the rear end of the pin roll is provided with an annular check ring, and the front end of the pin roll is provided with a mushroom-shaped pin roll protection base which is fixedly arranged on the suspension arm seat; a transverse nick is formed on in the external wall of the pin roll near the front end; the bottom of the mushroom-shaped pin roll protection base is provided with a bolt which is clamped on the transverse nick; and the ends end part of the bolt are is fastened by a slotted nut. The anti-smashing device of the pin roll of the suspension arm has a simple structure; by arranging the annular check ring and the mushroom-shaped pin roll protection base, the two ends of the bolt can be located in a protection range of the annular check ring and the mushroom-shaped pin roll protection base, so that the problems that a rear door is fallenfalls off because the pin roll is fallenfalls off due to being impacted by goods is solved fundamentally, and the stability of a finished automobile when moving is improved when moving are solved fundamentally.
Description
Technical field
The utility model relates to the anti-device of pounding of a kind of arm bearing pin.
Background technology
Existing self dumping lorory back door jack arm is connected the most spring cotters that adopt of bearing pin and fixes on the market with the arm seat, owing to will use spring cotter, bearing pin must expose a part, but bearing pin often is subject to the goods impact and is out of shape in the unloading process, thereby accelerated wear test, in the course of time spring cotter is pounded disconnected or is rubbed, and the danger that causes bearing pin to skid off to cause the back door to come off occurs.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of arm bearing pin simple in structure, easy to use the anti-device of pounding.
The anti-device of pounding of arm bearing pin of the present utility model; comprise the arm seat on two rear columns that are welded on the car side board assembly; be welded with the arm mutual corresponding with the arm seat on the edge column of carriage back door assembly both sides; be connected by bearing pin between arm and the arm seat; the rear end of bearing pin is provided with annular retaining ring; the front end of bearing pin is provided with the mushroom-shaped bearing pin protecting seat that is fixed on the arm seat; be provided with horizontal gap near the front end place on the outer wall of bearing pin; the bottom of mushroom-shaped bearing pin protecting seat is provided with the bolt that is fastened on the horizontal gap, and lock by fluted nut the end of bolt.
Arm bearing pin of the present utility model is anti-pounds device, between described mushroom-shaped bearing pin protecting seat and the arm seat by being welded to connect.
Compared with prior art the beneficial effects of the utility model are: it is simple that arm bearing pin of the present utility model prevents pounding apparatus structure; by annular retaining ring and mushroom-shaped bearing pin protecting seat are set; the two ends of bearing pin can be in the protection domain of annular retaining ring and mushroom-shaped bearing pin protecting seat; fundamentally solve because bearing pin comes off owing to being subject to the goods impact; the danger that causes the back door to be dropped occurs, and improves the stability problem in the car load driving process.
Description of drawings
Fig. 1 is the anti-structural representation of pounding device of the described a kind of arm bearing pin of the utility model embodiment;
Fig. 2 is the anti-connection structure scheme drawing of pounding annular retaining ring in the device, mushroom-shaped bearing pin protecting seat and bearing pin of the described a kind of arm bearing pin of the utility model embodiment.
Among the figure:
1, car side board assembly; 2, rear column; 3, arm seat; 4, carriage back door assembly; 5, edge column; 6, arm; 7, bearing pin; 8, annular retaining ring; 9, mushroom-shaped bearing pin protecting seat; 10, bolt; 11, fluted nut.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Shown in Fig. 1-2; the anti-device of pounding of a kind of arm bearing pin; comprise the arm seat 3 on two rear columns 2 that are welded on car side board assembly 1; be welded with on the edge column 5 of carriage back door assembly 4 both sides and the mutual corresponding arm 6 of arm seat 3; be connected by bearing pin 7 between arm 6 and the arm seat 3; the rear end of bearing pin 7 is provided with annular retaining ring 8; the front end of bearing pin 7 is provided with the mushroom-shaped bearing pin protecting seat 9 that is fixed on the arm seat 3; be provided with horizontal gap near the front end place on the outer wall of bearing pin 7; the bottom of mushroom-shaped bearing pin protecting seat 9 is provided with the bolt 10 that is fastened on the horizontal gap, and the end of bolt 10 is by fluted nut 11 lockings.
Arm bearing pin of the present utility model is anti-pounds device, between described mushroom-shaped bearing pin protecting seat 9 and the arm seat 3 by being welded to connect.
The anti-device of pounding of arm bearing pin of the present utility model is when concrete the use; mushroom-shaped bearing pin protecting seat and arm seat weld together; annular retaining ring is welded on the opposite side of arm seat; arm and arm seat are coupled together with bearing pin; bearing pin passes mushroom-shaped bearing pin protecting seat; align with the bolt hole of mushroom-shaped bearing pin protecting seat in the position of the horizontal gap of bearing pin band; with bolt and fluted nut bearing pin and mushroom-shaped bearing pin protecting seat are fixed together; the locking fluted nut; bearing pin is just stashed by mushroom-shaped protecting seat and annular retaining ring fully like this; avoid being subjected to external impacts; the mushroom-shaped of mushroom-shaped protecting seat can prevent also that bolt from being impacted directly by goods and cut off, thereby the situation of having avoided bearing pin to come off occurs.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
