摘要： PROBLEM TO BE SOLVED: To evaluate friction between a belt and a pulley of a belt-type CVT(continuously variable transmission), etc., in a dynamic state, and to separate the friction in the diameter direction and circumferential direction of the pulley. SOLUTION: A belt 10 wound over the pulley is sandwiched between pulleys 28 and 30 for measurement from the sides. Sliding in the direction of movement of the belt is made to occur between the pulley 28 for measurement and the belt 10, and a load torque at this time is measured by a torque meter 34. From the load torque, the radius of contact points between the belt and the pulley for measurement, and vertical load by a weight 48, the coefficient of friction in the circumferential direction are computed, and the pulley 30 for measurement is pulled upward by an actuator 44. The load necessary for the pulling is measured by a load cell 42 to compute the coefficient of friction in the radial direction from the measured value and vertical load by a weight 50.

摘要： PROBLEM TO BE SOLVED: To control the transmitting force arbitrarily without using a mechanical hydraulic mechanism and the like. SOLUTION: The transmitting force is controlled by utilizing that the friction coefficient of the friction surface is changed by giving the electric field to the friction surface of a friction engaging device. The friction engaging members are contacted directly each other by the function of a pushing force so as to friction engaged. When an electric field is given between the friction engaging members, the friction coefficient of the friction surface is changed, and the transmitting force can be changed. This friction engaging device is a clutch device 10, for example. A friction member 20 consisting of an insulation material is installed to an input disk 16, and the friction member 20 is engaged with an output disk 22. The friction surface is being lubricated. A control device 30 controls a voltage applying device 28, to apply the voltage to an electrode 26, and a desired transmitting force is obtained.

摘要： PROBLEM TO BE SOLVED: To improve a coefficient of friction by forming a base layer capable of elastically deforming at the frictional sliding time with a mating material on a support plate, and laminating a frictional surface containing a fiber basic material, filler material and a binder on the base layer. SOLUTION: A friction material is constituted of two layers of a base layer 1 and a friction surface layer 2. The layer 2 is fixed onto a support plate 3 via the base layer 1. The layer 1 has an elastic characteristic and is capable of elastically deforming according to the surface shape of a mating material when frictional sliding is made between it and the mating member. Owing to the elastic deformation of the layer 1, the layer 2 frictionally slides while following the surface shape of the mating material, and thereby the contact area with the mating material is increased, resulting in an increase in a coefficient of friction. In order to provide the layer 1 with an elastic characteristic, for example, the layer 1 is made of a rubber or resin plate or the like having a high elastic material. The layer 1 can also be made of a composite body composed of fibers and fiber entangled elastic fine particles.

摘要： PROBLEM TO BE SOLVED: To readily and inexpensively obtain the subject material useful for a wet clutch for an automobile, capable of securing a high coefficient of friction by the use of an organic paper-like base material, by including a paper-like base material composed of a fibrous material and an inorganic binder impregnated into the base material. SOLUTION: This friction material comprises (A) a paper-like base material composed of a fibrous material such as a linter pulp or the like and (B) an inorganic binder impregnated into the base material. The amount of the component B is preferably 10-70 vol.% based on 100 vol.% of the total of the component A and a friction adjuster, etc., and preferably contains two or more kinds of metal elements including at least a tetravalent metal element (e.g. silicon or the like). The friction material is produced by hydrolyzing at least one of a metal alkoxide (e.g. tetraethoxysilane or the like) and an organic group- substituted metal alkoxide (e.g. methyltrimethoxysilane or the like) to prepare a sol solution, impregnating the sol solution into the component A and drying/ baking.

摘要： PURPOSE:To stabilize the aging friction coefficient by forming a paper base material from a paper making raw liquid containing a fiber base material and a filler, coating fine fibers having the diameter of a specific value on the surface of the paper base material, impregnating it with a binder, and heating, pressurizing, and molding it. CONSTITUTION:Cellulose fibers and Aramid fibers are selected for base material fibers, and an inorganic filler, an organic filler, and water are added to prepare a paper making raw liquid. A paper base material having the preset thickness is made with this paper making raw liquid by a paper making machine, the friction surface is coated with fine fibers made of Aramid fibers and having the diameter of 2mum or below in the wet state to form a fiber-coated paper base material. It is dried by a hot press, it is impregnated with phenol resin serving as a binder, and it is thermo-molded and cut into the preset shape to obtain a friction material. When it is coated with fine fibers, the surface roughness is reduced, the contact area is increased, the initial friction coefficient is improved, and the aging change of the friction coefficient is resolved.

摘要： PURPOSE:To obtain a friction material of excellent heat resistance and durability, by overlapping a friction surface side layer, in which a paper quality base material consisting of fiber component, inorganic filling agent and a friction adjusting agent is impregnated with thermo-setting resin, with a fixed surface side layer, in which a paper quality material consisting of fiber component is impregnated with thermo-setting resin, and restricting gas holes in each paper quality base material. CONSTITUTION:Water soluble dispersion fluid 5, mixed with a fiber component, inorganic filling agent and a friction adjusting agent, is allowed to flow on a papermaking net 6, performing papermaking. Water soluble dispersion fluid 8, containing glass fiber and/or pulp, is allowed to flow on roll paper 7 made being not dried, obtaining two layers of paper quality components 10 as a base material performing papermaking. Next, this paper quality component 10 is impregnated with thermo-setting resin being heated and hardened, thus obtaining a wet type friction material 1. Here a friction surface side layer 2 forms its paper quality base material such that its porosity is 50-65% with gas holes of size of 5mu or less occupying 80% the total gas holes. A fixed side surface layer 3 sets each value to 40-70%. In this way, the wet type friction material excellent in durability and heat resistance can be obtained.
