摘要： A valve actuating cam has a periphery that can be varied in shape to control the opening and closing of one or more valves associated with a cylinder of an internal combustion engine. One portion of a valve assembly can be moved outwardly to change the valve lift. A band can surround the movable cam portion and cam body portion, and can form at least a major portion of the exterior surface of the cam that engages a cam follower such as a valve operating rocker arm. The timing of the opening and closing of one or more valves can be adjusted by adjusting the peripheral shape of the cam. The shape can be adjusted to start a ramp portion of the cam peripheral surface earlier to cause a valve to open earlier and to end a ramp portion later to cause the valve to close later with a first load on the engine and to open and close earlier when the engine is under a second load that is less than the first load. Wedges and wedging surfaces under the band and movable with the movable portion of the cam can be used to adjust the timing.

摘要： The compression ratio of an internal combustion engine is adjustable in a stepwise fashion, such as by pivoting an extension of an eccentric connecting rod bearing. The projection extends into a chamber defined by a portion of a connecting rod coupling portion of a connecting rod assembly. Liquid is delivered to one side of the projection and removed from the opposite side of the projection to move the projection and thereby the eccentric connecting rod bearing from one position corresponding to one compression ratio to another position corresponding to another compression ratio.

摘要： A vehicle axle construction comprises a suspension for supporting the axle from first and second frame rail members. Elongated support members extend forwardly from respective locations along the frame rail members that are rearwardly of the axle and are clamped or otherwise coupled to the axle. A single pivot may be utilized to couple the respective rearmost end portions of the supports to the respective frame members. The forward ends of the supports may be coupled to respective air springs. Desirably, at least a portion of each air spring is positioned forwardly of the axle. In addition, at least one lateral stabilizer rigidifies the suspension. An alternative suspension utilizes leaf springs. A double acting rack-and-pinion steering mechanism may be rigidly coupled to the axle for use in steering the wheels of the vehicle.

摘要： The parking brakes on a truck or other vehicle having plural axles are applied such that at least one wheel at a first end of a first axle receives a parking brake force without applying a parking brake force to any wheel at the opposite end of the first axle. In addition, at least one wheel at a second end of a second axle, the second end of the second axle being opposite to the first end of the first axle, receives a parking brake force. Desirably, any wheels at the opposite end of the second axle from the second end of the second axle are not the recipient of a parking brake force such that diagonally disposed parking brake forces are applied upon activation of the vehicle parking brakes. The first axle in one example is forwardly of the second axle and the first end of the first axle may be at the longitudinal side of the vehicle which is the heaviest.

摘要： A method and apparatus involves selectively relieving the load from the rearmost wheels of a trailer to shorten the effective wheel base of the trailer. When the effective wheel base is shortened, off-tracking of the trailer during turning is reduced. The load may relieved while the trailer and vehicle are traveling at, for example, less than a first speed, with the vehicle turning at least at a first angle. The axle may be reloaded when the vehicle speed is increased to a second speed above the first speed and the vehicle is turning at an angle which is less than the first angle.

摘要： An underhood air flow management system for a truck which includes cowl openings defined between cowl extensions and the rear edges of depending hood sections. Most preferably the cowl extension extends forwardly and inwardly toward the longitudinal centerline of the truck. The cowl extensions assist in deflecting air to the cowl openings, the air having passed through a radiator, along the sides of an engine and engine compartment, and through the cowl openings. The cowl openings preferably extend the full height of the depending hood sections. The bumper of the truck includes a lower extension. In addition, the front wheel wells of the truck are sealed at the front, partially sealed at the side and may be sealed at their rear to reduce the escape of air from the engine compartment through the front wheel wells. The cowl openings are preferably door-free and also lack air flow hindering severe transitions. A charge air cooler may be positioned ahead of the radiator and a fan may be positioned between the radiator and engine. Preferably the radiator is provided with seals so that air cannot enter the engine compartment without passing through the radiator. Seals may be provided between the charge air cooler and the radiator.
摘要翻译： 一种用于卡车的底座气流管理系统，其包括在前围罩延伸部和后排罩部分的后边缘之间限定的前罩开口。 最优选地，整流罩延伸部朝着卡车的纵向中心线向前和向内延伸。 整流罩延伸件有助于将空气偏转到前罩开口，空气已经沿着发动机和发动机舱的侧面通过散热器，并且通过整流罩开口。 整流罩开口优选地延伸排气罩部分的整个高度。 卡车的保险杠包括一个较低的延伸部分。 另外，卡车的前轮油井在前部密封，部分地密封在侧面，并且可以在其后部被密封，以减少来自发动机舱的空气通过前轮井的逸出。 整流罩开口优选是无门的，并且还缺少妨碍严重过渡的气流。 增压空气冷却器可以位于散热器之前，并且风扇可以位于散热器和发动机之间。 优选地，散热器设置有密封件，使得空气不能通过散热器而不能进入发动机室。 可以在增压空气冷却器和散热器之间设置密封。

摘要： Mechanisms are described for selectively closing grille and/or bumper openings. These mechanisms may be operated in response to one or more vehicle parameters. Closure mechanism control signals may be delivered to such mechanisms along a vehicle databus. In addition, vehicle parameters used in determining the control of such mechanisms may be sensed and provided along the databus to a controller which then processes the parameter information for determining whether to open or close the vehicle grille closing mechanism and/or the vehicle bumper opening closing mechanism.
