摘要： A shiftable toothed-belt drive, containing an engagement and disengagement device, in order alternately to mesh radially and demesh radially a toothed belt, which is guided around at least two gearwheels, with and from at least one of the two gearwheels. A disengager in the form of two externally profiled pulleys is urged axially along the shaft of one of the gearwheels supporting the toothed belt for radially raising the belt and demeshing the belt from the gearwheel. An engager engages the outside of the belt for tensioning the belt sufficiently to counter the effect of the disengager, move the pulleys apart and mesh the belt with the one gearwheel.

摘要： It is desired to improve the wear resistance of the valve seat of the check valve in a hydraulic tensioner. The hydraulic tensioner includes a cylinder having a hollow space filled with hydraulic oil. A plunger is slidably mounted in the cylinder. A pushrod is mounted in the hollow space so as to be axially movable together with the plunger with one end thereof protruding from the cylinder. A spring is mounted in the cylinder to bias the plunger and pushrod outwardly of the cylinder. The plunger is formed with a passage through which the pressure chamber and the reservoir chamber communicate with each other. The passage is formed with a valve seat. A check ball is arranged so as to be moved into and out of contact with the valve seat. The check ball is adapted to contact the valve seat when the pressure in the pressure chamber exceeds the pressure in the reservoir chamber, thereby closing the passage. The valve seat is formed of a steel for carburizing and has a surface carbon concentration of 0.55-0.75% to reduce deposition of carbides and to have a surface hardness at least equal to the check ball. This improves wear resistance of the valve seat and thus extends the life of the hydraulic tensioner.
摘要翻译：期望提高液压张紧器中止回阀的阀座的耐磨性。液压张紧器包括具有填充有液压油的中空空间的气缸。柱塞可滑动地安装在气缸中。推杆安装在中空空间中，以便与柱塞一起轴向移动，其一端从气缸突出。弹簧安装在气缸中以将柱塞偏压到气缸的外侧。柱塞形成有通道，压力室和储存室通过该通道彼此连通。通道形成有阀座。一个止回球被布置成与阀座移动和脱离接触。当压力室中的压力超过储存室中的压力时，止回球适于接触阀座，从而关闭通道。阀座由用于渗碳的钢形成，并且具有0.55-0.75％的表面碳浓度以减少碳化物的沉积并且具有至少等于止回球的表面硬度。这提高了阀座的耐磨性，延长了液压张紧器的使用寿命。

摘要： A belt tensioner for a power transmission belt may be provided that operates on an endless path and that utilizes asymmetric motion control. The belt tensioner may have an arm with a belt engaging section and a drum section, a support member for securing the tensioner relative to the belt, where the arm pivots on the support member, and a tension spring that urges the arm to pivot about the support member in a first direction and urges the belt engaging section against the belt with a force to tension the belt. The tensioner also may have a fluid filled chamber inside a portion of the drum section of the arm and a valve pivotally attached to the tensioner so that the valve extends across the fluid containing chamber.

摘要： A combination starter-generator system for use in a vehicle is provided. The vehicle has an internal combustion engine and a battery. The system includes a starter-generator electrically coupled to the battery to generate a current and to start the internal combustion engine. A drive mechanism connects the starter-generator machine and the internal combustion engine. The starter-generator machine generates the current by receiving a charging torque from one side of the drive mechanism and starts the internal combustion engine by imparting a starting torque to a different side of the drive mechanism. The charging torque or the starting torque is a greater torque. A passive tensioning system cooperates with the drive mechanism to tension the drive mechanism only at the side of the greater torque.

摘要： The belt tension/drive for a pinch roller system of the present invention combines means for urging a plurality of pinch rollers toward a capstan roller with means for driving pinch rollers when a pinch roller is not in contact with the capstan roller. The capstan roller is surrounded by and aligned with a plurality of pinch rollers. A resilient belt disposed about the plurality of pinch rollers urges the pinch rollers toward the capstan roller and drives any pinch roller not in contact with the capstan roller, assuring that all pinch rollers maintain the same surface speed as the capstan roller.

摘要： In a chain tensioner having a plunger biased to protrude from a housing by a spring, a pair of wedge-shaped cams are received in tapered recesses in the end of the housing, cooperate with racks formed on opposite sides of the plunger, and are urged against oblique seats formed by the tapered recesses by a biasing spring. The cams and racks produce a ratcheting action maintaining chain tension by preventing retracting movement of the plunger. The cams and racks disperse the load imparted to the plunger by the chain, and reduce localized wear, allowing the housing to be made from a light weight material such as aluminum. Accuracy requirements associated with conventional pawl-type ratcheting tensioners are avoided.

摘要： To provide a hydraulic tensioner, which can prevent the bottoming out or over-stressing of a spring in an incorporated check valve, can reduce the contact surface pressure between a check ball and a retainer, and can reduce the production cost, a hydraulic tensioner comprises a check valve incorporated in the housing which causes oil to flow into a high pressure chamber to block the back flow of oil. The check valve comprises a ball seat, a check ball facing the ball seat, a spring, which biases the check ball against the ball seat and a retainer, which retains the spring and limits the movement of the check ball. The spring comprises a conical coil spring, and the surface of the retainer, which retains the conical coil spring and limits the movement of the check ball, is formed in a flat surface.

摘要： A sliding contact guide for a chain, or other flexible transmission medium comprises a synthetic resin guide body having a shoe on which the transmission medium slides, and a slotted, plate-receiving portion on the back side of the shoe for receiving a reinforcing plate. The plate-receiving portion is composed of a pair of opposed, longitudinally extending, slot-defining walls. Raised ribs, for sandwiching the reinforcing plate, are disposed on opposed inner surfaces of the walls, and are oriented in the direction of insertion of the reinforcing plate into the slot. The guide suppresses shock noises due to wobbling of the guide during operation, and molding and assembly of the guide are enhanced.

摘要： In a ratchet-type hydraulic tensioner for a chain transmission, having a plunger and a housing forming a high pressure oil chamber, an excess supply oil discharge passage is provided. The discharge passage communicates with an oil supply passage leading from an oil supply opening, which receives oil under pressure from a oil pump, to a hydraulic check valve mechanism in the housing, which delivers oil to the high pressure oil chamber. Excess oil is discharged to the exterior of the tensioner housing and directed toward the chain. Excessive chain tension is avoided, and smooth and reliable chain travel, and suppression of whistling sounds, are achieved.
