Abstract: The present invention relates to a brake device comprising a number of brake discs, brake pads and brake pad holders being arragned for mutual co-operation after axial operation by means of actuators for braking. The brake pads are being carried by the brake pad holders that are connected to a first frame member. Ring shaped brake discs are carried by a second frame member. Brake pad holders and brake discs ate axially displaceable journalled relative to each other. The two frame members are arranged to be braked relative to each other actuation of axially acting actuators. In order to provide efficient cooling of the parts that comprises the brake, there are a number of passages provided in the brake drum for leading air internally to the brake system when the drum and the wheel rotates in the direction of travel.

Abstract: In a duo-pumping hydraulic mount, two acting pistons are employed, one associated with each working chamber. The pistons are rigidly connected. During operation, internal pressures generated in each chamber are opposite in sign with one being negative and the other being positive. Therefore, to achieve a given pressure differential across the fluid track, the magnitude of the pressure in each working chamber is half what would be experienced in a conventional single pumping mount. Durability is improved by reducing internal pressures and by distributing kinetic loads to two rubber elements so that individual stresses are minimized. An individual load bearing element supports static loads on the mount.

Abstract: A rough-terrain vehicle employs separate track drives located on opposite sides of a vehicle body, like the wheels of a car. The tractor drives can revolve the track to permit track-driven travel. The drives can also halt the tracks relative to the drives and rotated the entire track drive that supports the track in which case the track drive rotates like a wheel. The latter mode provides an ability to traverse very rough surfaces. To provide high ground clearance, the support connecting the track drive to the vehicle body is located above the axis of rotation of the track drive. Almost the entire transmission mechanism for the track drive is confined to a volume enclosed by the loop of the track protecting it. The track drive supports the track on a polar array of wheels, each located along the line that divides the track into two loops.

Abstract: A system of driving stability control, which is adapted to control valves for opening and closing hydraulic pressure passages between a master cylinder and brake units of wheels and simultaneously controls pressurizing valves and a pressure relief valves so as to supply braking force selectively and independently to the brake units when a specified driving condition is detected, performs the coordinated braking control that, when a specified step-on pressure is detected during execution of the driving stability control, delivers the braking pressure to the brake units according to brake pedal travels as the driving intends simultaneously with reducing the participative degree of the driving stability control so as to ensure gripping force of wheels that brake the vehicle and reduces reduce the participative degree of the driving stability control with an intention of regarding driving stability of the vehicle as important when the vehicle is going to cause a spin.

Abstract: A portable vehicle fluid drain device is disclosed. The device includes a vertical drain tube which supports a vehicle fluid drain bowl. The drain tube is manually adjusted to an elevated position, latched in place while the vehicle fluid is drained, and unlatched to descend at a rate less than that of free fall due to the use of a friction brake. The friction force imparted by the brake on the drain tube is adjusted by rotating a wing nut on a carriage bolt to squeeze the inner edges of two wishbone arms against the drain tube. A method of using a vehicle fluid drain device with a brake and a self-latching mechanism is disclosed.

Abstract: An electrically controlled braking system allows a pedal stroke produced by an operation of a brake pedal to be detected by a stroke sensor and to be input to a controller, which in turn controls a brake pressure generated by a brake pressure generator in accordance with the magnitude of the pedal stroke. A pedal reaction unit is added to the brake pressure generator. The pedal reaction unit comprises an air cylinder connected to the brake pedal, the stroke sensor which detects the pedal stroke, and a pair of solenoid operated open/close valves for feeding the air pressure from an air tank to, or displacing the air pressure from, the air cylinder. The controller causes the air to be fed to or displaced from the air cylinder in accordance with the magnitude of the pedal stroke detected by the stroke sensor, thus producing a pedal reaction having a controlled magnitude.

Abstract: A pneumatic cylinder, inside which a piston is displaced and which defines two chambers. The chambers are communicated through a first conduit passing through the piston and a second conduit at the ends of which there are variable flow valves. The first conduit has an adjustable valve. The load at any air chamber results in a working load which causes contact of the wheel with the ground for a longer period of time. An expansion spring is located at the lower air chamber. The piston is engaged with means for sensing its displacement. The invention could be applied to any kind of vehicle.

Abstract: A bushing for a vehicle suspension system has a hollow cylindrical sleeve and a hollow cylindrical jacket, with first and second elastomeric members compressively preloaded into an annular space between the sleeve and the jacket. The elastomeric members, which are complementary in filling the annular space, are selected from different materials possessing different spring rates. The elastomeric members are preferably semicircular radial sections of an annulus. When the bushing is aligned in the vehicle suspension, the bushing exhibits at least one diameter where the bushing effectively has a first spring rate when the bushing is acted on by a force in a first radial direction and exhibits a different spring rate when the bushing is acted upon by a force in a second radial direction which is one hundred eighty degrees opposed to the first radial direction.

Abstract: The invention relates to a hydraulic unit having an hydraulic block, with magnet valves inserted in apertures therein. The magnet valves include protruding valve domes on which coils are mounted. The magnet valves and coils are covered by a covering hood. For sealing purposes, a platelike sealing element, includes a beadlike edge which forms an outer sealing body. The outer sealing body rests between an edge of the covering hood and the hydraulic block, and includes inner bead-like sealing bodies, which rest between the coils of the magnet valves and the hydraulic block. The inner bead-like sealing bodies are integral, via a diaphragm or the like, with the outer sealing body. The sealing body includes a multiple sealing at the edge of the covering hood and individual sealing of each magnet valve. In addition, the inner sealing bodies act as spring elements, which press the coils against retaining struts in the interior of the covering hood and thereby fixes the coils on the valve dome.

Abstract: The cylinder is filled with damping medium. The vibration damper also includes a damping valve which is active as a function of pressure. The damping force of the damping valve can be modified by means of an actuator against a spring force on a shutoff valve body. An admission valve with its own damping action is connected hydraulically in series with the damping valve, so that the action of the admission valve is superimposed on the action of the adjustable damping valve.

Abstract: A vehicular anti-lock brake system utilizes a follow valve (also known as a copy valve) in place of a conventional solenoid valve. The follow valve causes brake fluid pressure for a wheel brake to follow and imitate the brake fluid pressure of a wheel brake controlled by a solenoid valve. The follow valve exclusively regulates fluid pressure at a wheel brake so that fluid pressure is substantially similar to fluid pressure at a wheel brake controlled by a solenoid valve.
