[specific embodiment]
Below in conjunction with accompanying drawing the specific embodiment of the invention is described in detail:
Fig. 1 is the present invention program's scheme drawing, and as shown in Figure 1, vehicle suspension of the present invention comprises vehicle frame 1, operator's compartment 2, and shock absorber 4, spring 5 is formed.It is characterized in that: each suspension assembly reaches the screw mechanism of the symmetric arrangement of being made up of screw rod 7 and nut 6 with a motor 8; The rotating shaft of motor 8 is coaxial with screw rod 7, and the rotation of screw rod 7 drives by motor 8.
This levitation device has two kinds of implementations:
Scheme one:
As can be seen from Fig. 1,, and respectively arrange a suspension assembly, just can realize the suspension of whole operator's compartment at the front and back position of operator's compartment 1 if arranging about this levitation device assembly.So its feature also is: levitation device assembly left and right directions is arranged, can be realized the suspension of whole operator's compartment by respectively arrange a levitation device assembly at operator's compartment 1 front and back position.
In this scheme, the levitation device assembly is connected between vehicle frame 1 and the operator's compartment 2 in the following manner.Wherein the upper end is fixed on the operator's compartment 2 by motor 8; Simultaneously, the screw rod 7 on symmetrical screw mechanism both sides is installed the connection that realizes on the attached seat 3 with operator's compartment 1 with the levitation device that the rotation width of cloth is installed on operator's compartment the right and left respectively; In addition, each levitation device assembly is with two pairs of shock absorbers 6 and two pairs of springs 5, and the every pair of shock absorber 6 and spring 5 are coaxial and axisymmetricly, shock absorber 6 upper ends are connected on the nut 6 of screw mechanism with pin, and the lower end is connected on the vehicle frame 1 with pin.
From scheme one as seen, if starter motor forward or reverse, just can realize making the nut 6 on both sides to move to car front and back line of centers or car both sides synchronously, change the levitation device support angle α between operator's compartment 2 and the vehicle frame 1, thereby reach the purpose that changes levitation device stiffness coefficient and damping coefficient certificate.
By regulating the levitation device assembly of forward and backward position respectively, can realize the front and back pitch regulation function of vehicle cab 1, improve the vehicle ride comfort.
Scheme two:
From Fig. 2 as seen, the present invention can arrange levitation device assembly fore-and-aft direction, can realize the suspension of whole operator's compartment by arrange a levitation device assembly at the right and left.Thereby realize implementation two of the present invention.In this scheme, the levitation device assembly is the same, and promptly it has outside the common trait of scheme one.
In this scheme, the levitation device assembly is connected between vehicle frame 1 and the operator's compartment 2 in the following manner.Wherein the upper end is fixed on the operator's compartment 2 by motor 8; Simultaneously, the screw rod 7 on symmetrical screw mechanism both sides is installed the connection that realizes on the attached seat 3 with operator's compartment 1 with the levitation device that the rotation width of cloth is installed on the operator's compartment front and back position respectively; In addition, each levitation device assembly is with two pairs of shock absorbers 6 and two pairs of springs 5, and the every pair of shock absorber 6 and spring 5 are coaxial and axisymmetricly, shock absorber 6 upper ends are connected on the nut 6 of screw mechanism with pin, and the lower end is connected on the vehicle frame 1 with pin.
From scheme two as seen, if starter motor forward or reverse, 6 steps of nut that just can realize making suspension assembly both sides before car or the car rear to moving, change the levitation device support angle α between operator's compartment 2 and the vehicle frame 1, thereby reach the purpose that changes a lateral suspension device stiffness coefficient and damping coefficient.
By regulating the levitation device assembly of left and right position respectively, can realize the side tilt angle regulatory function of vehicle cab 1, improve the vehicle ride comfort.
Scheme three:
Above-mentioned two schemes are fixed on operator's compartment 2 belows to motor 8, can certainly be fixed on motor 8 on the vehicle frame 1, as shown in Figure 3, scheme three is that motor 8 is fixed on the vehicle frame 1, by changing the arranged direction and the position of the floating assembly of devices in the name of a river in Anhui Province, equally can implementation one and the said function of scheme two.
Scheme four:
Certainly, also can only be arranged vertically shock absorber 4, spring 5 is regulated by screw rod 7 or spring 5 is arranged vertically, and shock absorber 4 is regulated by screw rod 7.Realize half active adjustment function of regulating spring rigidity only or damping coefficient.
Can be from last visible the present invention as the cab suspension device of various civil cars, because the road surface that military trucks travel is relatively poor, ride comfort is had relatively high expectations, and cab suspension device of the present invention can be according to load carrying ability, different levitation device rigidity and the damping coefficients regulated with moving velocity of track, and realize the attitude of operator's compartment simultaneously with respect to vehicle frame.Obviously be very suitable for the suspension requirement of wheel military vehicle.
Those skilled in the art can carry out other change and modification after reading patent specification of the present invention, but these changes and modification are all within the claim protection domain that the present invention is awaited the reply.
