The invention relates to a disc brake comprising a brake caliper (1), which engages over a brake disc that can rotate on an axis (A) and brake linings (2, 3) arranged on both sides thereof in a lining groove (6), comprising a hold-down arrangement (8) formed by a rigid hold-down piece (7) and a leaf spring (9) and leading transversely over the brake linings (2, 3), wherein the hold-down piece (7) has a central section (7b) forming the majority of its total length and leading over the lining groove (6), and two end sections (7a, 7c), wherein the hold-down piece is supported against the brake linings (2, 3) towards the disc brake axis (A), and wherein said hold-down piece extends at least partially into a slot (14) of the brake caliper (1) with the first end section (7a) thereof, and wherein the leaf spring (9) extends in the longitudinal direction of the hold-down piece (7) and is spring-elastically supported against the outer side of the hold-down piece (7) facing away from the brake linings (2, 3). In order to more simply configure the fixing of the elements of the hold-down arrangement in terms of assembly and production, without thereby weakening the fixture, the first end section (7a) of the hold-down piece (7) is angled in relation to the central section (7b).

A vehicle suspension arrangement includes a leaf spring assembly with at least two leaf springs which are arranged, during use in a vehicle, with a longitudinal extension generally coinciding with the longitudinal extension of said vehicle; the suspension arrangement includes a spring clamping unit connecting the leaf springs to an axle in the vehicle; and wherein each of the leaf springs includes end sections which are configured to be fastened in a vehicle chassis. Furthermore, the spring clamping unit includes a spacer component which is configured for separating the leaf springs in a vertical or horizontal direction.

A vehicle leaf spring shackle includes pair of longitudinal plate members opposed to each other, pair of devices for connecting the pair of longitudinal plate members to each other at their opposite end portions with respective predetermined spacing distances, and between pair of longitudinal plate members, one pair of devices is coupled to a member of a vehicle body while other pair of devices is coupled to one end portion of a leaf spring device provided to suspend the vehicle body. At least one end portion of the pair of longitudinal plate members on the leaf spring device side including a thick-walled portion formed with thickness larger than other portions of the pair of longitudinal plate members, the thick-walled portion is formed by press-forming operation to press at least one end portions of the longitudinal plate members on the leaf spring device side, in direction of the end portion plane.

A leaf spring device includes a main leaf made of a steel plate including an elastic section configured to generate elastic force when bent; and an eye section formed in an end portion of the elastic section, the elastic section and the eye section being tempered. There is also provided a method for manufacturing the leaf spring device. The eye section is formed by rolling the end of the elastic section into a circular form. The eye section is tempered at a higher temperature than the elastic section.

A vehicle spring for a spring system, includes a spring body (20) and is produced, in particular rolled, from a profiled bar (1) made of a flat steel bar, in particular spring steel, in a hot deformation process. The profiled bar (1) or the spring body (20) has at least one material recess (6) which is provided over the length of the profiled bar or the spring body at least in some regions. The cross-sectional shape of the profiled bar (1) can be the same over the entire length of the profiled bar, whereas the cross-sectional shape in the spring body (20) can vary over the length of the spring body.
