摘要:
A vehicle is provided with an optimum suspension/chassis state and run for a first period of time under a predetermined condition, for storing information related to outputs of force sensors, as a reference value. The state of the vehicle may change due to the use thereof, thus it is run for a second period of time under the predetermined condition. An analyzing apparatus analyzes a change of an alignment state of the vehicle on the basis of information stored from the first and second periods.
摘要:
A vehicle state analyzing system which allows the state of a vehicle to be grasped is provided. A vehicle 10 which is provided with an optimum suspension/chassis state is run for a certain period of time under a predetermined condition, such as straight running, or the like, for storing the information related to the outputs of force sensors 14 in a first storage area as the reference value. The state of the vehicle 10 may change due to the use thereof, thus it is rum under a predetermined condition in the same manner as when the reference value has been stored as appropriate, for storing the information related to the outputs of the force sensors in a second storage area An analyzing apparatus 20 is capable of analyzing the state of the vehicle 10 on the basis of the information stored in the first storage area and the information stored in the second storage area. For example, when the toe angle, the camber angle, the internal pressure for the tire, or the like, is changed in the vehicle 10, the inputs of force from the wheels to the vehicle body is changed, which allows a change in state of the vehicle 10 to be grasped.
摘要:
A heavy duty pneumatic radial tire includes a carcass consisting of at least one layer of metal cords substantially radially arranged, a breaker consisting of at least two layers of metal cords to form a main reinforcement with the carcass, and bead portions including hard and soft stiffeners. The carcass has a particular radial profile having a ratio of radii R/R' determined by a radius R' of a standard circle and a radius R determined by a particular definition and has a maximum distance f between an arc of the standard circle and the remaining carcass line smoothly extending from the profile curvature of the shoulder. Moreover a radial profile over a radially inner zone of the sidewall of 20-45% of the radial height SH has a curvature 1/.rho. less than 6.times.10.sup.-3 mm.sup.-1 at a location 32.5% of the radial height corresponding to a center of the profile.
