Description of drawings
The present invention is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 swings the structural representation of suspension for the present invention,
Fig. 2 swings the scheme drawing that suspension is installed on vehicle for the present invention.
The specific embodiment
As shown in Figure 1, the swing suspension of the large-scale transport vehicle of the present invention comprises upper cantilever 1, lower cantalever 2, single acting oil cylinder 5, heavily loaded energy storage 9, underloading energy storage 10, suspension installation sleeve 6, captive nut 8 and damping gum cover 7; Described upper cantilever 1 and lower cantalever 2 each end flexibly connect by bearing pin 3 and guide 4, the base 51 of described single acting oil cylinder 5 is located on the described upper cantilever 1 by bearing pin 53 activities, the piston rod 52 of described single acting oil cylinder 5 is located on the described lower cantalever 2 by the bearing pin activity, described suspension installation sleeve 6 is fixed at vehicle bridge 13 middle parts that two ends connect wheel, described damping gum cover 7 is located in the described suspension installation sleeve 6, other end captive joint vehicle frame 14 bottoms of described upper cantilever 1, the other end of described lower cantalever 2 is provided with outside thread and stretches in the damping gum cover 7 of described suspension installation sleeve 6, the outside thread of described lower cantalever 2 other ends is positioned at outside the described suspension installation sleeve 6 and is screwed with described captive nut 8, described heavily loaded energy storage 9 and underloading energy storage 10 are respectively spherical and inner chamber is divided into two and forms two cavitys 11 and 12, be marked with nitrogen and hydraulic oil respectively in two cavitys of described heavily loaded energy storage 9 and underloading energy storage 10, described heavily loaded energy storage 9 is consistent with the hydraulic oil capacity in underloading energy storage 10 cavitys, nitrogen pressure in described heavily loaded energy storage 9 cavitys is greater than the nitrogen pressure in described underloading energy storage 10 cavitys, the cavity that described heavily loaded energy storage 9 and underloading energy storage 10 are marked with hydraulic oil is connected the hydraulic fluid port of described single acting oil cylinder 5 respectively by hydraulic tubing, described heavily loaded energy storage 9 and underloading energy storage 10 are located at described vehicle frame 14 bottoms.
For making the reasonable distribution of this swing suspension load, the piston rod 52 of above-mentioned single acting oil cylinder 5 is located at described lower cantalever 2 middle parts by the bearing pin activity.
Further, be the load effect that guarantees that this swing suspension is good, the nitrogen pressure that injects in above-mentioned heavily loaded energy storage 9 cavitys is 80-160bar, the nitrogen pressure that injects in above-mentioned underloading energy storage 10 cavitys is 20-40bar, and the hydraulic oil that injects in above-mentioned heavily loaded energy storage 9 and underloading energy storage 10 cavitys is 0.4-1L.Through experiment, during hydraulic oil 0.6L, its effect is preferable in heavily loaded energy storage nitrogen pressure 160bar, underloading energy storage nitrogen pressure 30bar, heavy duty and the underloading energy storage cavity.
In this swing suspension, upper cantilever and lower cantalever link together by bearing pin and guide, can rotate mutually around bearing pin, thereby the vehicle bridge of vehicle and vehicle frame can be moved up and down, and quicken, slow down, at the uniform velocity reach the strong and moment of transmitting reliably when static between vehicle bridge and the vehicle frame of institute at vehicle, constituted the guiding mechanism of vehicle; Single acting oil cylinder links together by hydraulic tubing and heavily loaded energy storage, underloading energy storage, and has constituted the elastic element and the damping element of this swing suspension with the damping gum cover, is used for relaxing from ground-surface impact the decay vibrations; Single acting oil cylinder can satisfy the heavily loaded requirement of vehicle as elastic element; Wherein, the nitrogen pressure that heavily loaded energy storage is filled is big and nitrogen pressure that the underloading accumulation of energy is filled is little, thereby makes single acting oil cylinder obtain the support of different-stiffness, can guarantee the stationarity in the vehicle ' preferably; The point of action of single acting oil cylinder is between upper cantilever and lower cantalever, and the load of vehicle bridge is half of oil cylinder approximately, and the stroke of vehicle bridge is a times of oil cylinder approximately.
As shown in Figure 2, can adopt many this swing of cover suspensions to be installed between the vehicle frame 14 and each vehicle bridge 13 of vehicle, single acting oil cylinder 5 epicoeles of respectively swinging suspension during installation are communicated with by hydraulic tubing, and when vehicle moved, the hydraulic oil of single acting oil cylinder 5 was in closed condition by closing of hydraulic control one-way valve;
On more smooth road surface, for the small impact of ground-surface, the increase of gas volume or minimizing come supplementary sum to receive the interior hydraulic oil of single acting oil cylinder in two energy storages of main dependence, thereby guarantee the suitable ground pressure of tire, alleviate and absorbing vibration, the damping gum cover that be connected in lower cantalever this moment also plays certain cushioning effect.
And on the fluctuating road surface, mainly play cushioning effect by single acting oil cylinder, the single acting oil cylinder epicoele that respectively swing suspension this moment is communicated with, the hydraulic oil of stressed single acting oil cylinder can flow in the not stressed single acting oil cylinder by hydraulic tubing, thereby absorbed vibrations, guaranteed the stress balance of each vehicle bridge of vehicle.
Uneven or local when concavo-convex about the road surface, because the suspension installation sleeve is located at the middle part of vehicle bridge, vehicle bridge can be rolled to each side around lower cantalever, guaranteed the ground pressure of vehicle tyre, absorb and impact.At Ackermann steer angle, because the stressed variation of left and right wheels that force of inertia causes also can be recompensed around the swing of lower cantalever both sides by vehicle bridge, certainly, the pressure of respectively swinging the suspension single acting oil cylinder this moment also will produce corresponding the variation equally.Vehicle bridge when planar horizontal requires on satisfying vehicle frame, has also adapted to situation uneven about the road surface around the swing of lower cantalever both sides.
This swing suspension is different from existing various types of vehicles suspension, is a kind of new vehicle suspension that collects existing various types of vehicles suspension advantage; The point of connection of this swing suspension and vehicle bridge is at the middle part of vehicle bridge, and vehicle bridge can swing around lower cantalever, and this is that traditional suspension is not available.
From guiding mechanism, the beating of left and right sides wheel of this swing suspension interacts, and belongs to non-independent suspension; But from same axis (about respectively adorn one group of suspension), belong to the category of independent suspension again.We can say that it is between independent and non-independence.
This swing suspension elastic element is made of jointly damping gum cover, single acting oil cylinder and twin-stage rigidity energy storage, and each oil cylinder epicoele is communicated with.Combine the characteristics of hydro pneumatic suspension and balance suspension.
The upper cantilever of this swing suspension and lower cantalever are variable by single acting oil cylinder adjusting height, suspension rate, belong to the mixing of active suspension and passive suspension.Because upper cantilever, lower cantalever and oil cylinder allow rising, the descending stroke of vehicle bridge big, be fit to the variation of multiple road conditions simultaneously, regulate the height of vehicle simultaneously by single acting oil cylinder, guaranteed the crossing ability that vehicle is good.
