The screw pitch of spring, thickness are equal to the spring filament diameter of helical spring；
With the oil inlet other end with oil outlet, oil inlet, oil outlet connect for the one end of elastic housing in the longitudinal direction
It connects pressure oil receiving portion and forms pressure oil flow cycle, pressure oil receiving portion connects compression pump；
Power control unit connects compression pump, and is adjusted to shell internal cavity by adjusting the watt level of compression pump
The amount of pump-in pressure oil, power control unit are configured as：
The big data from long-range car networking data center is received, big data includes the road surface top of vehicle current driving road
Degree of winnowing with a dustpan and congestion level；
Receive driver's operation information from entire car controller, when driver selects driving mode for motor pattern, work(
Rate control unit makes compression pump with high power operation, and the amount for being pumped into the pressure oil of shell internal cavity is larger, and the hardness of conveyor screw improves,
Suspension more meets the driving demand of motor pattern；When driving mode is switched to comfort mode, power by driver by motor pattern
Control unit makes compression pump with low power run, and the amount for being pumped into the pressure oil of shell internal cavity is smaller, and the hardness of conveyor screw reduces, and hangs
Frame more meets the driving demand of comfort mode；
Under comfort mode, power control unit herein in connection with the road bump extent control compression pump received power,
When the value of road bump degree is larger, power control unit further decreases the power of compression pump, makes to be pumped into shell internal cavity
The amount of pressure oil further decreases, to be maintained to preferable comfort on the track to jolt, when road surface is run
When the value for degree of winnowing with a dustpan is smaller, the power of compression pump is reverted to initial size by power control unit.
Power control unit herein in connection with receive congestion level control pressure pump power, when current driving road more
Congestion, then vehicle need continually to start to walk, brake, this will bring the pitching of vehicle body multifrequency time, bow to inhibit this as possible
It faces upward, then no matter which kind of current driving mode is, power control unit all makes compression pump with high power operation.
By means of the invention it is possible to its hardness is dynamically adjusted according to driver's operation information and big data, it is electronic to make
The soft or hard degree of vehicle suspension more meets the requirement of driving, optimizes driving experience, and it is tied for air spring
Structure is simple, can directly install additional and realize on the basis of conventional absorber spring, reduce cost.
Description of the drawings
Fig. 1 shows the coil spring assembly of the application；
Fig. 2 shows the sections of the coil spring assembly of the application；
Fig. 3 shows the section of the conveyor screw of the application.
Specific implementation mode
With reference to the accompanying drawings, the function that the structure of the present apparatus is described in detail and is realized.
As shown in Figs. 1-3, coil spring assembly 1 includes helical spring and conveyor screw 3, and conveyor screw 3 includes elastic housing 3.1
With the pressure oil 3.2 being filled in shell internal cavity, conveyor screw 3 is set around adjacent two spring silks 2 of the central section of helical spring
Between, adhesion is fixed in the both ends in width direction with spring silk, and the width of conveyor screw is approximately equal to the screw pitch of helical spring, and thickness is about
Equal to the spring filament diameter of helical spring；
With 4 other end of oil inlet with oil outlet 5, oil inlet 4 goes out for the one end of elastic housing 3.1 in the longitudinal direction
Hydraulic fluid port 5 connects pressure oil and accommodates 6 formation pressure oil flow cycles, and pressure oil receiving portion 6 connects compression pump 7；
Power control unit (not shown) connects compression pump 7, and is adjusted by adjusting the watt level of compression pump 7
To the amount of shell internal cavity pump-in pressure oil, power control unit is configured as：
The big data from long-range car networking data center is received, big data includes the road surface top of vehicle current driving road
Degree of winnowing with a dustpan and congestion level；
Receive driver's operation information from entire car controller, when driver selects driving mode for motor pattern, work(
Rate control unit makes compression pump 7 with high power operation, and the amount for being pumped into the pressure oil 3.2 of shell internal cavity is big, and the hardness of conveyor screw 3 carries
Height, suspension more meet the driving demand of motor pattern；When driving mode is switched to comfort mode, work(by driver by motor pattern
Rate control unit makes compression pump 7 with low power run, and the amount for being pumped into the pressure oil 3.2 of shell internal cavity is small, the hardness drop of conveyor screw 3
Low, suspension more meets the driving demand of comfort mode；
Under comfort mode, power control unit herein in connection with the road bump extent control compression pump 7 received power,
When the value of road bump degree is larger, power control unit further decreases the power of compression pump 7, makes to be pumped into shell internal cavity
The amount of pressure oil 3.2 further decreases, and to be maintained to preferable comfort on the track to jolt, works as road surface
When the value for degree of jolting is smaller, the power of compression pump 7 is reverted to initial size by power control unit.
Power control unit herein in connection with receive congestion level control pressure pump 7 power, when current driving road compared with
For congestion, then vehicle needs continually to start to walk, brake, this will bring the pitching of vehicle body multifrequency time, in order to inhibit this as possible
Pitching, then no matter which kind of current driving mode is, power control unit all makes compression pump 7 with high power operation.
