Abstract:
A heavy-duty vehicle brake assembly with a sealing interface includes a brake shoe, which includes a shoe table mounted on a web and a brake lining mounted on the shoe table. The shoe table is coated with a zinc-rich coating to form the sealing interface between the brake lining and the shoe table. The sealing interface resists the formation of corrosion cells on the brake shoe table, which in turn reduces the build-up of significant rust between the brake shoe table and the brake shoe lining, thereby preventing cracking and potential dislodging of the lining, while also facilitating replacement of linings when they eventually wear. A method of constructing a heavy-duty vehicle brake assembly with a sealing interface is also provided.
Abstract:
The invention relates to an inert gas system (24), particularly for aircrafts (10). The inert gas system (24) comprises an inert gas reservoir (64), provided in a wing (12) or a fuselage (14), for supplying inert gas to the at least one fuel tank (16, 78). Inert gas is supplied via a piping system (26, 28) to at least one brake disc pack (36) of at least one landing gear (18). Inert gas supplied generates an oxygen reduced atmosphere at the at least one brake disc pack (36).
Abstract:
A method for forming a material for a brake disc, the method comprising the steps of : (i) providing at least one porous body; (ii) introducing into pores of the porous body one or more precursor materials for forming or depositing a ceramic material; and (iii) forming the brake disc material by forming or depositing the ceramic material from the precursor material within the pores of the body, wherein the precursor material is a liquid containing a suspension of ceramic particles and/or acid phosphate.
Abstract:
A method for antirust treatment of a rotating brake member, wherein outer side and inner side rubbing surfaces, (2a) and (3a) respectively, of a disc brake rotor (1) made of cast iron are subjected to an electrolysis treatment in a phosphate film forming solution containing a phosphoric acid ion, a zinc ion and a nitric acid ion, to thereby form a zinc phosphate film (8) having a film thickness of 1 to 10 νm, desirably 2 to 8 νm, a mass of 4 to 35 g/m2 and a crystal grain size of 50 νm or less on the rubbing surfaces. The treatment according to the method markedly improves the antirust corrosion resistance of rubbing surfaces, (2a) and (3a).
Abstract:
Means for inhibiting corrosion of a brake disc (15) of a disc brake assembly (10) associated with a road wheel (12) of a motor vehicle, comprising a member (11) adapted to be fitted in the road wheel and partially to define a volume containing the brake disc, said member including means for emitting a corrosion inhibiting vapour in said volume.
Abstract:
In a brake disc rotor 1, at least a road wheel mounting plane 6 is covered with a rust preventive coating 8 of rust preventive paint. The rust preventive paint is water-borne acrylic-denatured epoxy resin paint containing aluminum zinc phosphomolybdate as a rust preventive pigment, and is applied in such a manner that the coating 8 attains a thickness t of 1 to 20 µm, preferably 5 to 15 µm.
Abstract:
A material part (3,28,71,91,110), in particular a metal component made of an aluminium alloy having a slide surface with which another part is slidably contactable is provided with at least a first plating layer (13) of a material having a high wear-resistance. In order to reduce the influence of different thermal expansion and contraction, a fine network of cracks (15) is formed in the plating layer (13).
Abstract:
The invention discloses a brake cylinder dust cover and a waterproof brake cylinder using such dust cover. The brake cylinder comprises a brake cylinder body and a front cover. A waterproof dust cover assembly is arranged on the front cover. The waterproof dust cover assembly comprises a dust cover fixedly connected to the front cover, and a filter felt support and a filter felt pad which are arranged in the dust cover. The filter felt support is connected with the dust cover, and the filter felt pad is fixed on the filter felt support. An outwards extending skirt is arranged at the edge of the dust cover in the axial direction thereof. By providing an existing brake cylinder with a sealing structure at the position liable to water, the invention can effectively prevent rain water from being sucked into the cylinder by the negative pressure formed in the brake cylinder when the brake cylinder is released, thus playing the waterproof role, which increases the service life of the cylinder and ensures safe driving.
