Rear axle 1 is included, spring base ontology 3 is installed on the rear axle 1, to ensure to have sufficient space device for installing and adjusting, spring base lift
Angle should not design too small (being advisable greater than 6 °), and spring supporting circle is bigger, and under vehicle loading condition, active spring coils gap can be got over
It is small, to meet the requirement that the effective ring gap of limiting condition is not less than 3mm, need to consider reserved space, the spring at the beginning of design
The side of seat ontology 3 offers sliding slot 2, and the internal activity of the sliding slot 2 is connected with spring base sliding block 4, the spring base sliding block 4
On helical spring 5 is installed, to ensure that stability that spring uses, lower spring end bracing ring minimum cannot be maximum less than 0.6 circle
1 circle is not exceeded, it can be achieved that change within 6% range of spring rate, the side of the rear axle 1 is fixedly connected with bracket 6, institute
It states and box body 7 is installed on bracket 6, the top of the box body 7 is equipped with nut 8, and the internal whorl of the nut 8 is connected with screw rod
9, the lower end of the screw rod 9 is linked with turbine 10, and the side engagement of the turbine 10 is connected with worm screw 11, and the worm screw 11 is installed
In on the output shaft of motor 12, installation lifting device and driving motor are required to carry out support Design, which also will increase whole
The unsprung mass of vehicle considers lightweight requirements, need to carry out optimal design to supporting structure and material and on the other hand drive
Motor and lifting device will select small-sized as far as possible in the case where meeting life requirements, the threaded upper ends of the screw rod 9 are connected with
Threaded sleeve 13, the threaded sleeve 13 are fixedly connected on the bottom of spring base sliding block 4, and spring base consists of two parts, can be with
Realize the switching that circle number 0.75 circle with 1 circle are bonded between spring base and spring, to change spring supporting circle number, spring entrucking is rigid
Degree is changed, and does not have particular requirement to spring structure, can directly continue to use conventional helical spring structure, and lower spring end bracing ring is
When one circle, spring rate is in maximum position in variable range, and vehicle traveling maneuvering performance is best, when bumpy road of passing through
When, it for driving comfort, needs to reduce spring rate, needs to decline spring base sliding block at this time, after the decline of spring base sliding block, bullet
Spring lower end bracing ring is equivalent to less than a circle and increases the number of active coils of spring, spring rate is minimized.
