Abstract: Provided is a vehicular pedal device, wherein a master cylinder, which is connected to a clutch pedal via a piston, and which generates hydraulic pressure via a movement of the clutch pedal, is positioned further toward a passenger compartment side of a dash panel which separates a drive source mounting chamber from the passenger compartment, said vehicular pedal device comprising a pedal support bracket which supports the clutch pedal upon the dash panel. The pedal support bracket configures a cylinder part which houses operating oil of the master cylinder.

Abstract: A vehicle pedal resistance and kickdown assembly including a plunger moveable in a housing between first and second positions. The plunger defines a recess for a rod, A first spring in the housing biases the plunger in the first position. A second spring retains the rod in the plunger recess in the first position. In one embodiment, the recess in the plunger is an elongate recess in a flat front face of the plunger. In one embodiment, the housing defines an aperture in a to or bottom wall of the housing that has a length greater than the length of the second spring and the second spring is inserted lengthwise into the housing through the aperture. In one embodiment, the second spring is retained in a clip in the housing.

Abstract: An adjusting device for automatically actuating a vehicle door of a motor vehicle includes first and second tubular housings connected between a body of the vehicle and the door. A spindle drive includes a spindle driven by an electric-motor drive, a spindle nut threaded on the spindle, a push rod that bears the spindle nut, and a tubular guide part enclosing the push rod and the spindle nut. The tubular guide part is provided with a shape complementary to a shape of the spindle nut and secures the spindle nut against rotation. The tubular guide part is produced by a plastic forming process on a suitable metal tube. A cylindrical spring assists the spindle drive enclosing the tubular guide part. Spacers are provided over an outer circumference of the tubular guide part to reduce friction between the cylindrical spring and the tubular guide part.

Abstract: A damping device, including: a wedge assembly having a wedge including a vertical surface and an inclined surface; a primary friction board disposed on the vertical surface; and a secondary friction board disposed on the inclined surface; and a damping spring assembly disposed underneath the wedge assembly. The wedge assembly has the following structure parameters: ?=16-30°, and ?<tg?<?+?1, where ? represents an included angle between a friction surface of the secondary friction board and a vertical plane, ? represents a friction coefficient of the primary friction board, and ?1 represents a friction coefficient of the secondary friction board.

Abstract: To provide a spring assembly whose production cost is low. It includes a coil spring 1, and a pair of retainers 2 disposed respectively at opposite end portions of the coil spring 1, and the retainer 2 includes a plate member 3 abutting against the end portion of the coil spring 1 and depressed at a central portion thereof toward the inside of the coil spring 1, and a hook member 4 fixed to the plate member 3 so as to hold a free length of the coil spring 1 shortened.

Abstract: The invention relates to a damping device for movable furniture parts, for example for doors or drawers, comprising a piston or plunger which is slidably guided in a hollow body, e.g. a cylinder, with said piston or plunger being impinged upon by spring force into its pushed-out position. According to the invention, the hollow body comprises at least one section of a spiral-shaped stay of the internal screw thread, and/or the piston or plunger comprises at least one section of a spiral-shaped stay of the external screw thread. The stays of the screw threads are glidingly supported one on top of the other, or cams or journals of the hollow body or of the piston or plunger are supported on a screw-thread section of the other component. The pitch of the stays of the screw threads is greater than the pitch at which self-locking occurs.

Abstract: A shock absorber, the shock-absorbing function of which can be turned on/off during movement and includes a basement, a clutch assembly, a control assembly and a shock-absorbing spring, the shock-absorbing spring provides damper elastic force for the respective components of the shock absorber. The shock-absorbing function can be turned off when riding up a slope, so as to prevent the drag force being increased by the up and down motion of the shock absorber. The shock-absorbing function can be turned on when riding on a horizontal road, and it can be turned off again when riding down a slope, so as to prevent the increase of the front tilt angle of the bike and leading to turnover.

Abstract: A shear mount assembly and a compression mount assembly are combined to control ride harshness of a shock absorber. The shock absorber includes a body and a shock rod having a hydraulically sealed portion within the body and a distally extending free portion. A mount assembly is connected at the free portion having both a compression mount and a shear mount therein. The shear mount absorbs low-input vertical loads transferred from the shock rod, and the compression mount limits vertical displacement of the shear mount and absorbs a medium-input vertical load. The shear mount and the compression mount are tuned by selecting the durometer, dimensions, and physical configuration of each mount.

Abstract: A damping system for a rail car truck utilizes friction wedges supported on side springs to damp relative movement between the rail car truck bolster and the side frames supporting it. Each friction wedge has a generally triangular shape with an angle &thgr; defined between a vertical friction surface which bears against a side frame and a sloping friction surface which moves relative to the bolster. The angle &thgr; and the force P of each side spring are defined by Fw W .

Abstract: A control pedal assembly for a motor vehicle includes a support structure, a pedal arm pivotally mounted to the support structure and carrying a pedal, and a sensor for detecting rotation of the pedal arm and sending an electrical signal to a control device indicating the rotation of the pedal arm. The pedal assembly also includes a hysteresis device adapted to generate a desired feel in response to pivotal movement of the pedal arm. The hysteresis device is secured to the support structure and includes a plunger engaging the pedal arm and is movable within a chamber between an extended position and a depressed position upon rotation of the pedal arm. A pair of coaxial compression springs resiliently bias the plunger to the extended position. The chamber forms a first friction surface and the plunger has a plurality of prongs forming a second friction surface engagable with the first friction surface to resist pivotal movement of the pedal arm.
