Abstract:
A straddle-type vehicle seat includes: a saddle-type seat main body which is provided above a vehicle body in one of a three-wheel straddle-type vehicle and a four-wheel straddle-type vehicle and which is straddled by a driver; and an angle adjustment mechanism which adjusts an angle of the saddle-type seat main body with respect to the vehicle body in accordance with a signal from a detection unit that detects a traveling state of the straddle-type vehicle when the straddle-type vehicle is turning.
Abstract:
A damping force generator for a hydraulic shock absorber featuring an increased deflection (bending) characteristic of a damping valve to widen the adjustable range of a damping force. In a damping force generator (70) for a hydraulic shock absorber, the damping valve (80) undergoes deflections with boundaries (71C) between secured portions (71A) and recessed portions (71B) of the valve seat (71) as supporting points K, and inner and outer peripheries of the damping valve (80) are disposed on an outside of line segments L each connecting two circumferentially adjacent supporting points K, K of the valve seat (71).
Abstract:
A suspension apparatus includes: a partition wall member that divides a space inside an inner tube into an upper space and a lower space; a cap that covers an upper opening portion of an outer tube; and a support member of which one end portion is retained by the cap, and of which the other end portion supports the other end portion of a piston rod, in which a through-hole is formed in a portion of the inner tube, an inner space of the piton rod is a space inside the piston rod and communicates with the lower space, the support member is a cylindrical member and forms an upper portion space, and the upper portion space communicates with the inner space of the piston rod, and at least one of the cap and the support member is provided with a communication path.

Abstract:
A relative angle detection apparatus includes a first magnetometric sensor and a first voltage amplifier that output a signal corresponding to a relative rotation angle between a first rotation shaft and a second rotation shaft; a first amplifier circuit that amplifies the output signal of the first voltage amplifier; a second magnetometric sensor and a second voltage amplifier that output a signal that corresponds to the relative rotation angle; a second amplifier circuit that amplifies the output signal of the second voltage amplifier; a first resistor that is provided between the first amplifier circuit and a power supply terminal, or between the first amplifier circuit and a GND terminal; and a second resistor that is provided between the second amplifier circuit and the power supply terminal, or between the second amplifier circuit and the GND terminal.
Abstract:
A hydraulic shock absorber provides, a ring-shaped flow passage formed continuously along a circumferential direction between an outer circumference of a partition wall member and an inner circumference of an inner tube, in a range from an abutting surface to a screw coupling starting portion of a thread section of the inner tube; an outer side flow passage which is formed to a ring-shaped oil chamber side from a dividing member positioned on an open end surface side of the inner tube and which connects a ring-shaped oil chamber and the ring-shaped flow passage, an inner side flow passage which is formed in the partition wall member and which connects the ring-shaped flow passage and an oil reservoir chamber.
Abstract:
A vehicle height adjusting apparatus of a motorcycle includes a damper-side ECU connected to a vehicle network in which in-vehicle ECUs and a vehicle operating state detecting sensor which are mounted on a vehicle are connected to each other, in which the damper-side ECU attached to a damper, computes a vehicle height change to be adjusted in the damper using a detection result of a vehicle height detecting unit and a detection result of the vehicle operating state detecting sensor and controls a switching valve to adjust a vehicle height on the basis of the computed vehicle height change.
Abstract:
A pressure buffer device includes a bypass path configured to form a channel of the oil from the a second oil chamber to the a first oil chamber, a slit valve connected to the bypass path, configured to form an inflow route of the oil from the bypass path to a pressure chamber, and having a channel sectional area smaller than a channel sectional area of the bypass path, and a communication path connected to the bypass path, configured to form an inflow route of the oil from the bypass path to an annular recess, and having a channel sectional area larger than the channel sectional area of the slit valve and smaller than the channel sectional area of the bypass path.
Abstract:
A front fork spring leg, which is capable of stably maintaining air spring, has an inward-facing seal member, an outward-facing seal member, and a piston ring arranged on an outer periphery of a guide of a guide rod sequentially in this order along an axial direction of the guide from a side close to an inner air spring chamber toward a side far from the inner air spring chamber. The inward-facing seal member has a lip which is slidably in contact with an inner periphery of the guide cylinder, with this lip being oriented toward the inner air spring chamber. The outward-facing seal member has a lip which is slidably in contact with the inner periphery of the guide cylinder, with this lip being oriented in an opposite direction to the inner air spring chamber.
Abstract:
A seat damper attached between a vehicle body and a seat in a seat suspension structure. The seat damper capable of allowing misalignment of mounting positions of mounting parts between the vehicle body side and the seat side, and being configured with reduced rigidity. The seat damper includes: a resilient member interposed between a vehicle body and a seat, supporting a load applied thereto; a seat-side bearing plate and a vehicle body-side bearing plate sandwiching the resilient member; a rod including a joint for pivotably coupling the rod to the seat-side bearing plate and a locking portion at the other end locking the rod to a lower face of the vehicle body-side bearing plate, with this joint being received in and locked to the seat-side bearing plate; and a ring-like rod guide provided to the vehicle body-side bearing plate for the rod to pass through.
