摘要:
This invention aims to allow one of a pair of auxiliary apparatus and the other of the auxiliary apparatus to be handled independently of each other, while satisfying the need to be installed in a limited boarding space and the need to be produced at low production costs. For this purpose, this invention allows an autotensioner idler (ID) which serves as one of the auxiliary apparatus and a viscous heater (VH) which serves as the other of the auxiliary apparatus to transmit power to each other and to be attachable to and detachable from each other.
摘要:
A heating system incorporating a heat generator confining therein a heat-generative fluid to viscously generate heat when a shearing action is applied to the fluid by a rotor element, and a heat-generation controller including a heat-generation adjusting actuator which adjustably changes the heat-generating performance of the heat generator on the basis of a signal detected as a first control signal indicating a change in the rotating speed of the rotor element and a preset reference signal. A second control signal detected to indicate a temperature of the heat-generative fluid is used to adjustably change the preset reference signal. The operation of the heating system is controlled by a method in which the first control signal is compared with the preset reference signal to determine whether or not the heat-generation adjusting actuator should actuated to change the heat-generating performance of the heat generator. The method is performed so as to adjust the preset reference signal on the basis of the second control signal which is detected by a temperature sensor.
摘要:
A torque limiting apparatus is located between a power source and a driven apparatus. A number of breakable power transmission members connect a drive rotor to a driven rotor. The breakable members are fractured to disconnect the driven rotor from the drive rotor when the load applied by the driven apparatus exceeds a predetermined value. A promoting member is located near at least one of the power transmission members for promoting breakage when the load causes the driven rotor to rotate relative to the drive rotor. The breakable members are broken consecutively. The breakable members are not significantly affected by fatigue.

A viscous fluid type heater including a stator having a stationary surface and a rotor having a rotary surface. The rotary surface is opposed to the stationary surface to define a clearance therebetween for the accommodation of a viscous fluid. A circulating fluid flows through a heat exchanging chamber. The rotor rotates about its axis and shears the viscous fluid to produce heat. The heat is transmitted to the circulating fluid from the viscous fluid. The rotary surface is inclined with respect to the rotor axis. The stationary surface is inclined in conformity with the rotary surface.

An improved heating apparatus for a vehicle is disclosed. A water circuit circulates water to cool an engine. A viscous fluid type heater is disposed in a fluid circuit that is separately arranged from the water circuit. The heater has a heating chamber and a heat exchange chamber close to the heating chamber. The heat exchange chamber communicates with the fluid circuit. The heating chamber accommodates viscous fluid and a rotor rotatable to shear the viscous fluid for producing heat. The heat is transmitted to the heat exchange chamber from the heating chamber. The fluid in the heat exchange chamber is heated and flows to the fluid circuit.
