In the present invention, in order to provide an electrode active material that has a high capacity density and from which a large current can be extracted and to provide a battery that has a high energy density and produces a large output, in a battery comprising at least a cathode, an anode and an electrolyte, a polyradical compound having a partial structure represented by the following general formula (2) is used as an electrode active material for at least one of the cathode and the anode, wherein, in the formula (2), Rto Rindependently represent a hydrogen atom or a methyl group; and Rto Rindependently represent an alkyl group having 1 to 3 carbon atoms.

Method for manufacturing polyradical compound and battery

An independent suspension for a vehicle, including upper and lower arms pivotally moveable in a vertical direction of the vehicle, an axle with a wheel center which is connected with the upper and lower arms, and a tie rod connected with the axle at a connection point rearward of the wheel center in a fore-and-aft direction of the vehicle. The lower arm is connected to the vehicle body at front and rear connection points spaced from each other in the fore-and-aft direction of the vehicle through front and rear pivot shafts with bushings. The central axis of the front pivot shaft is inclined relative to the central axis of the rear pivot shaft in a toe-in direction of the wheel.

Independent suspension for vehicle

Provided is a vehicle suspension member assembly suitable for a multi-link type rear suspension system. The suspension member assembly includes a pair of front and rear cross members and a pair of side members which are joined to constitute a generally rectangular suspension member subassembly. A pair of rear resilient supports are disposed at the opposite longitudinal end portions of the rear cross member. A pair of front resilient supports are disposed at the front end portions of the side members. The rear ends of the side members are attached to the front surface of the rear cross member. The front cross member is disposed between the side members and have opposite longitudinal ends attached to the inner side surfaces of the side members. To the rear cross members are provided a pair of brackets by means of which a rear connecting portion of a lower link is attached to the suspension member assembly.

In order to reduce a partially concentrated load affecting a spring seat by repulsion of the coil spring, an edge of the upper end of the coil spring is disposed against a portion of the spring seat having a relatively low solidity. Therefore, it is possible to eliminate the problem that the coils of the coil spring interfere with each other if a mid-portion of the coil spring in vertical direction is offset to the side to provide a partially concentrated load.

Structure for mounting a coil spring to a vehicle body and method therefor

In order to simplify mounting a coil spring to a vehicle body, a connecting device, which connects a spring bracket to the vehicle body, is disposed at an inner circumferential portion of the coil spring. This eliminates the problem that the spring bracket needs a space for connecting to the vehicle body about an outer circumference of itself.

Structure for mounting a coil spring to a vehicle body and method

A wheel suspension for rear wheels of an automotive vehicle, comprises a coil spring on a rear lateral link having an articulation point on an axle housing, a front lateral link, a radius rod and an upper arm having an articulation point on the axle housing at a position higher than a wheel center. A shock absorber is arranged such that its longitudinal axis crosses the wheel center as viewed the axle housing in a transverse direction with respect to a normal forward driving direction. The upper arm is connected to a suspension member via a forward pivot and a rearward pivot. The arrangement is such that loading the axle housing at the connection point with the upper arm in a rearward direction with respect to the normal forward direction causes the upper arm to position the connection point inwardly with respect to the vehicle body, and loading the axle housing at the connection point in the normal forward direction causes the upper arm to position the connection point outwardly with respect to the vehicle body.

Rear wheel suspension

A rear wheel suspension arrangement for an automotive vehicle provides an axle housing rotatably mounting rear vehicular road wheels, each of the wheels having a wheel center. At each wheel, a radius rod which extends forwardly and inwardly, as viewed in a normal forward direction of the vehicle, is connected to the axle housing at a first articulated connection at a position lower than the wheel center. Further, a front lateral link, extending generally transversely to the forward direction of the vehicle is connected to the axle housing at a second articulated connection also located below the wheel center. In addition, a rear lateral link, positioned rearwardly of the front lateral link and extending in the traverse direction of the vehicle, is connected to the axle housing at a third articulated connection also located below the wheel center. The suspension structure also includes an upper arm having an articulated connection to the axle housing at a position above the wheel center. A coil spring is disposed between a lower side of a vehicle body and an upper surface of the rear lateral link, while a shock absorber having a coaxially mounted bump rubber provided at an upper side thereof is connected at an upper end thereof to the vehicle body and at a lower end thereof to a fourth articulated connection at an upper side of the axle housing.

Wheel suspension for rear wheels

An axle supporting member for a rear wheel is suspended to a suspension member by an upper link system which includes an A-arm and a side rod. The forward lower link member and the side rod are respectively arranged in front and rear of a vertical plane passing through a rotary axis of the rear wheel, while a suspension spring and a shock absorber are seated on the forward lower link member positioned in front of the above-mentioned vertical plane with respect to the longitudinal direction of the vehicle. Accordingly, an initial load transmitted from the suspension spring is mainly borne by the front end part of the suspension member, so that an initial load exerted to the rear end part of the suspension member becomes smaller. Thereby, it is possible to reduce the resilient deformation of bushings in the front and rear parts of the suspension member upon application of a wind-up input force.
