摘要:
A disc brake (1) for allowing a piston (9) in a cylinder (13) to press friction pads (5,6) against a rotor (3) by means of an oil pressure supplied to a caliper body (7), wherein an electric oil pressure generator (15) is incorporated in the caliper body (7) with a solid element capable of controlling electrically an expansion/contraction operation used as a drive source and is connected to the cylinder (13) via an oil passage (29) formed in the caliper body (7), thereby eliminating the need of an oil pressure pipeline between a cylinder on the caliper body and the electric oil pressure generator and enhancing the operational accuracy and maintainability of the disc brake.
摘要:
A method of producing friction materials is capable of avoiding the problems in work environment due to the coarse particulates or organic solvents while producing the friction materials. The method includes processes of mixing under dry condition raw materials consisting primarily of thermosetting resin binders, fibrous reinforcing materials and friction modifiers, adding and mixing adhesives consisting of mixture of water and alcohol with the raw mixture so that the raw materials are wet and have viscosity. Afterwards, the wet raw mixture is granulated to form a granule material, dried, and heated-and-pressed to form a final product.
摘要:
In an anti-lock control arrangement for preventing locking of vehicle wheels, a prescribed speed difference of a threshold speed from an estimated vehicle speed is changed from an initial value of the difference to a larger value when a wheel speed has been lower for a prescribed time than the threshold speed which follows the estimated vehicle speed with the prescribed speed difference therefrom or when a prescribed statement with respect to the wheel speed is repeated at a predetermined number. Further, the speed difference of the threshold speed from the estimated vehicle speed is changed back to the initial value when the wheel speed has become lower than the threshold speed subjected to the former change.
摘要:
A friction material containing dust having bismaleimidetriazine as a major ingredient. The dust is effective when contained in amount of 1 to 20 wt. % in the friction material. Compared with conventional friction material containing cashew dust, the generation rate of noise is reduced drastically, while the frictional performance is equivalent or higher.
摘要:
A method of inspection of products comprising the steps of striking a surface of product by a striker device, detecting the time period while the striker contacts the product by way of a force sensor, and determining the quality of the product on the basis of the time period while the striker contacts the product.
摘要:
A traction control method/apparatus for motor vehicles is arranged such that at an initial stage of the starting or accelerating operation of the motor vehicle where a large amount of slip of the driving wheel tends to be caused, a braking force is sufficiently applied to the driving wheel to restrain the slip thereof; and after the engine output is adjusted through accelerator or throttle control which is performed simultaneously with the application of the braking force, the procedure for controlling the brake hydraulic pressure is changed to eliminate the difference between the lefthand and righhand driving wheel speeds.
