Abstract
A suspension device (S) of the present invention comprises: an actuator (A) including a motion conversion mechanism (T) for converting a linear motion to a rotational motion, and a motor (M) connected to a rotational member (1) which performs the rotational motion in the motion conversion mechanism (T); a fluid pressure damper (D) connected to a linear motion member (2) which performs the linear motion in the motion conversion mechanism (T); a mount (22) connected to a sprung member of a vehicle; and suspension springs (38) and (38) interposed between the mount (22) and an unsprung member, the actuator (A) being elastically supported by the mount (22) through a rubber vibration isolator (21).
Claims20
A suspension device comprising:
- an actuator including a motion conversion mechanism for converting a linear motion to a rotational motion, and a motor connected to a rotary member which performs the rotational motion in the motion conversion mechanism;
- a fluid pressure damper connected to a linear motion member which performs the linear motion in the motion conversion mechanism;
- a holder retaining said motion conversion mechanism by an inner circumference thereof, said holder being connected to said motor;
- a mount connected to a sprung member of a vehicle through a rubber vibration isolator;
- a first rubber vibration isolator mounted on an outer circumference of said holder to connect said holder to said mount;
- and
- a suspension spring interposed between the mount and an unsprung member, said mount including a mount cylinder connected to said first rubber vibration isolator, a plate connected to said sprung member, and a second rubber vibration isolator connecting said mount cylinder and said plate, said actuator being elastically supported through said first rubber vibration isolator and said second rubber vibration isolator.
A suspension device comprising:
- an actuator comprising a motion conversion mechanism and a motor, said motion conversion mechanism comprising a threaded shaft, said motion conversion mechanism converting a linear motion of said threaded shaft to a rotational motion;
- a fluid pressure damper connected to said threaded shaft;
- a holder connected to said motion conversion mechanism and said motor, said holder comprising an outer circumference;
- a first rubber vibration isolator mounted to said outer circumference of said holder;
- a mount connected to a sprung member of a vehicle, said mount comprising a mount cylinder, a plate and a second rubber vibration isolator, said second rubber vibration isolator connecting said mount cylinder to said plate, said actuator being elastically supported via said first rubber vibration isolator and said second rubber vibration isolator, said mount cylinder being connected to said first rubber vibration isolator;
- a suspension spring arranged between the mount and an unsprung member.
A suspension device comprising:
- an actuator comprising a motor, a threaded shaft, a ball screw nut and a converting means for converting a linear motion of said threaded shaft to a rotational motion of said ball screw nut;
- a fluid pressure damper connected to said threaded shaft;
- a first rubber vibration isolator;
- a mount connected to a sprung member of a vehicle, said mount comprising a mount cylinder, a second rubber vibration isolator and a plate, said mount cylinder being connected to said first rubber vibration isolator, said plate being connected to said sprung member, said mount cylinder being connected to said plate via said second rubber vibration isolator;
- a holder having an outer circumferential surface and an inner circumferential surface, said inner circumferential surface defining a space, at least a portion of said converting means being arranged in said space, said holder being connected to said motor, said first rubber vibration isolator engaging at least a portion of said outer circumferential surface;
- and
- a suspension spring arranged between the mount and an unsprung member.
