A utility vehicle disk brake includes a vehicle-mounted brake carrier that partially surrounds a brake disk, and a brake caliper that is arranged on and partially covers the brake carrier.

A first one of the sliding guides is designed as a fixed bearing, and a second one of the sliding guides is designed as a floating bearing. At least the floating bearing is designed as a slotted guide having a guideway that runs in the sliding direction of the brake caliper as well as a first guiding element that is accommodated in the guideway.

An electric vehicle includes a modular support structure having a central frame module and front and rear frame modules in the form of a lattice framework, having two upper longitudinal beams and two lower longitudinal beams connected to each other by uprights and cross-members. The front frame module carries a front suspension with wheel supports carried by upper and lower oscillating arms, and a front electric motor unit including two electric motors, having respective motor axes coincident with each other and arranged along a transverse direction with respect to a vehicle longitudinal direction. The motors are positioned spaced apart from each other, and are symmetrical with respect to a vehicle median line. Two gear reducing units are arranged centrally between the two electric motors, with housings having lateral walls from which output shafts project, which are connected by drive shafts to wheel hubs rotatably mounted on the wheel supports.

A transmission brake device includes: a friction plate set configured such that a plurality of rotation-side friction plates; an engaging piston disposed on an axial side of the friction plate set; a clearance adjustment piston disposed on a side of the engaging piston opposite to the friction plate set; a clearance adjustment hydraulic chamber configured to move the clearance adjustment piston; and an engaging hydraulic chamber configured to move the engaging piston; a biasing member disposed between each adjacent pair of the fixed-side friction plates, the biasing member being configured to bias each adjacent pair of the fixed-side friction plates in directions away from each other. The biasing member distributes the clutch clearance in a gap between each adjacent pair of the fixed-side friction plates when a hydraulic pressure is supplied only to the clearance adjustment hydraulic chamber.

A detection device is described for detecting a force acting in a detection portion of a brake caliper and representative of a braking torque acting on the brake caliper when braking. The device is adapted to being mounted between the brake caliper detection portion and a corresponding hub holder by means of fixing and clamping means. When mounted and in the absence of forces acting on it, the detection device is shaped as a washer or plate extending mainly along a reference plane. The device may have a first functional element, a second functional element, a positioning element, and a sensing element.

A device for indicating the wear of a brake lining of a disc brake, which triggers a signal when a wear limit of the brake lining is reached, includes a circlip (10) and a sensor (32) with a sensor head (34). The sensor (32) can be fastened in a bore of the brake lining and has a groove (36) that receives the circlip (10) to secure the sensor (32) on the brake lining. The groove (36) has a flattened region, and the shape of the circlip (10) is adapted to the flattened region. The circlip (10) has a region (12) which has a uniformly round curvature, and has bends (18, 20) in the direction of a centre (25) of the circlip (10) at the ends (14, 16) of this region (12). End pieces (22, 24) extend from the bends (18, 20) and have straight regions that are parallel and aligned.

A land vehicle includes a frame structure, a plurality of wheels supported by the frame structure, and a body supported by the frame structure. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The body includes a first sidewall arranged on one side of the vehicle and a second sidewall arranged on another side of the vehicle opposite the first sidewall.

A brake clip is described. The brake clip can include a U-shaped body; a clip channel; and a return spring, wherein the clip channel is defined by: a clip base comprising a stop tab; a pad tensioner; and the channel side tab; wherein, the clip base is connected to the pad tensioner and the channel side tab to form a channel; the return spring is connected to the clip channel at a rotor side edge of the clip channel and extends over the clip base; the clip channel is configured to fit into a channel on the brake pad carrier and to receive a brake pad; and the stop tab extends into the clip channel and is configured to press on a brake pad backing plate when a portion of the brake pad backing plate is located in the clip channel.

A wet brake includes a housing, non-rotatable brake discs, rotatable brake discs, a parking lever, a piston, a plate, and a connector. The non-rotatable and the rotatable brake discs are disposed in engagement with the housing and an outer peripheral surface of a rotary shaft, respectively. The piston, the plate, and the rotary shaft are accommodated in the housing. The piston is configured to be pushed by the parking lever toward the non-rotatable and the rotatable brake discs. The plate is in contact with one of the non-rotatable brake discs or one of the rotatable brake discs. The connector is disposed at a position between the piston and the plate. The housing has a recess that is formed in an outer peripheral surface of the housing at a position corresponding to the position of the connector. An outer diameter of the connector is smaller than that of the piston.

A test bench for screwdrivers comprises a hydraulic brake unit (11) provided with a coupling (12) for a screwdriver to be tested and angle and torque measurement transducers (15). The brake unit (11) comprises a disk (40) axially connected to the coupling (12) so as to be rotated by a screwdriver to be tested, and braking plates (42, 43) pushed in a controllable manner with their braking surfaces (44, 45) against the disk (40) by means of a plurality of pistons (46, 47) supplied with fluid by an electrovalve (16). The pistons (46, 47) of the plurality can be selectively activated under the control of the control unit (26) so as to select a maximum braking torque of the brake. The control may be performed by means a PID controller (19) which receives an electrovalve control signal (22) from a control unit (26) so as to follow braking curves depending on the angle of rotation and/or torque measured and has parameters which can be set using different sets of parameters. A method for controlling the bench is also described.
