Abstract
The utility model discloses an explosion-proof diesel engine trackless rubber-tyred vehicle for mine, which consists of a frame, a rear axle and an axle suspension device connected between the frame and the rear axle. The axle suspension device consists of two cantilevers. A sleeve is arranged at the intersection of the two cantilevers. The utility model is characterized in that the axle suspension device and the frame are connected together through a three-dimensional connecting piece. Since the axle suspension device and the frame are connected together through the three-dimensional connecting piece, when compared with the previous suspension method, the freedom degree of an axle moving relatively to the frame is added and the relative transverse movement between the axle and the frame is restricted, the impact of the rear axle to the frame is greatly reduced, the force applied onto the splint, the connecting bolt, the spring and the like of the axle is improved and the landing method of the tyres of the vehicle is improved, and thereby the bearing capacity, the reliability and the passing ability of the rubber-tyred vehicle are improved and the service life of the rubber-tyred vehicle is prolonged.
Description
Technical field

Background technology
Mine anti-explosion diesel engine railless free-wheeled vehicle is used in the transportation of large-scale coal mine personnel and material, because service conditions is abominable under the coal mine, strict to each part reliability of rubber-tired cart, rubber-tired cart is provided with a vehicle bridge suspension gear between vehicle frame and back axle, make rubber-tired cart when broken terrain advances, play the effect of buffering, but existing vehicle bridge suspension gear is directly to be associated on the vehicle frame by a pivot pin, the on-the-spot result that uses shows under coal mine, its bearing, reliability, crossing ability etc. all need to improve, and make cross member of frame easily, the vehicle bridge clamping plate, tie bolt, the phenomenon of fracture appears in springs etc.
The utility model content
Technical problem to be solved in the utility model provides a kind of bearing, reliability, mine anti-explosion diesel engine railless free-wheeled vehicle that crossing ability is high.
For solving the problems of the technologies described above, the utility model provides a kind of mine anti-explosion diesel engine railless free-wheeled vehicle, comprise vehicle frame, back axle and be connected in vehicle frame and back axle between the vehicle bridge suspension gear, described vehicle bridge suspension gear comprises two cantilevers, the intersection of described two cantilevers is provided with sleeve, it is characterized in that: described vehicle bridge suspension gear links to each other by a three-dimensional activity attaching parts with vehicle frame.
Described three-dimensional activity attaching parts comprises a reclinate supporting plate in middle part, described supporting plate two ends are by bolt and vehicle frame Joint, described supporting plate middle part has a square opening, be provided with rubber cushion cover in the described square opening, and be fixed in the square opening by upper and lower two projections, the both sides of described rubber cushion cover are provided with first pressing plate and second pressing plate, and first pressing plate, rubber cushion cover and second pressing plate are passed in second rotating shaft; Described three-dimensional activity attaching parts also comprises " [" type rotating shaft housing, between two relative edges of described rotating shaft housing, be provided with first rotating shaft, described first rotating shaft penetrates in the sleeve, the outside, the 3rd limit of described second rotating shaft and rotating shaft housing links to each other, and the described second rotating shaft other end is by second outside that is bolted to first pressing plate.
The beneficial effect that the utility model reached:
Mine anti-explosion diesel engine railless free-wheeled vehicle of the present utility model, by a three-dimensional activity attaching parts vehicle bridge suspension gear is connected with vehicle frame, Duoed the degree of freedom of a relative frame movement of vehicle bridge than hang in the past, and on cross motion, limited the relative motion of vehicle bridge and vehicle frame, greatly reduce the impact of back axle to vehicle frame, improved the mode that lands of the stressed and vehicle tyre of vehicle bridge clamping plate, tie bolt, spring etc., bearing, reliability, the crossing ability of rubber-tired cart are improved, thereby prolonged the service life of rubber-tired cart.
Description of drawings

Fig. 2 is a mine anti-explosion diesel engine railless free-wheeled vehicle vehicle bridge suspension gear part upward view of the present utility model;
Fig. 3 be among Fig. 1 A-A to front view.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.Fig. 1 is a mine anti-explosion diesel engine railless free-wheeled vehicle vehicle bridge suspension gear part front view of the present utility model; Fig. 2 is a mine anti-explosion diesel engine railless free-wheeled vehicle vehicle bridge suspension gear part upward view of the present utility model; Fig. 3 be among Fig. 1 A-A to front view.
A kind of mine anti-explosion diesel engine railless free-wheeled vehicle of the present utility model, comprise vehicle frame 11, back axle 12 and be connected in vehicle frame and back axle between the vehicle bridge suspension gear, described vehicle bridge suspension gear comprises two cantilevers 10, the intersection of described two cantilevers 10 is provided with sleeve 9, it is characterized in that: described vehicle bridge suspension gear links to each other by a three-dimensional activity attaching parts with vehicle frame 11.
Described three-dimensional activity attaching parts comprises a reclinate supporting plate 13 in middle part, described supporting plate 13 two ends are by bolt and vehicle frame 11 Joints, described supporting plate 13 middle parts have a square opening, be provided with rubber cushion cover 2 in the described square opening, and be fixed in the square opening by upper and lower two projections 4, the both sides of described rubber cushion cover 2 are provided with first pressing plate 1 and first pressing plate 1, rubber cushion cover 2 and second pressing plate 3 are passed in 3, the second rotating shafts of second pressing plate; Described three-dimensional activity attaching parts also comprises " [" type rotating shaft housing 7, between two relative edges of described rotating shaft housing 7, be provided with first rotating shaft 8, described first rotating shaft 8 penetrates in the sleeve 9, described second rotating shaft links to each other with the outside, the 3rd limit of rotating shaft housing, and the described second rotating shaft other end is fixed on the outside of first pressing plate 1 by second bolt 6.
Be provided with rotary sleeve 14 between the described sleeve 9 and first rotating shaft, described rotary sleeve 14 is two, is arranged at sleeve 9 inboard two ends respectively.
The utility model is because the rubber cushion cover 2 that second rotating shaft, 5 places adopt polyurethane material to do has been avoided the direct contact between second rotating shaft 5 and the supporting plate 13, and is stressed more even, plays the effect of buffering better; When the road surface of back axle by the front and back injustice, can rotate around first rotating shaft 8, about passing through, back axle can rotate around second rotating shaft 5 longitudinally during uneven road surface, make back axle in load-bearing, Duoed the degree of freedom of a relative frame movement of vehicle bridge than hang in the past, and on cross motion, limited the relative motion of vehicle bridge and vehicle frame, greatly reduce the impact of back axle to vehicle frame, improve the mode that lands of the stressed and vehicle tyre of vehicle bridge clamping plate, tie bolt, spring etc., thereby prolonged the service life of rubber-tired cart.
