Abstract

PURPOSE:To prevent a power transmission system for right and left driven wheels from being needlessly rotated to reduce travelling resistance and thereby prevent any noise from being produced by halving the spindle of car wheels and providing a changeover switch operated by an electromagnet at two-wheel drive travelling. CONSTITUTION:A spindle 3 is halved into a car wheel side part 31 including a hub 4 fixed thereon and an acceleration shaft side part 32 connected to a synchro-joint 8. At four-wheel driving where a transfer clutch is turned on, rear wheels including the spindle 3 are driven for rotation due to rotation of an engine. When the transfer clutch is turned off, a two-wheel driving state is caused, allowing the rear wheels to be changed over to the driven wheels. With a changeover switch 14 changed over, a current is conducted to the electromagnet 13 to cause a slide sleeve 11 to be attracted and slidden, resulting in a clutch-off state. Accordingly, rotation from the car wheel side is interrupted at the clutch part, causing all of acceleration shaft side part 32, synchro-joint 8, and the acceleration shaft 9, etc., to be stopped.

A part-time 4WD vehicle has already been developed in which the vehicle can switch from a four-wheel drive state in which the vehicle is rotatably driven to a two-wheel drive state in which power transmission to the rear wheels is stopped by disengaging the transfer clutch. It is publicly known (see Japanese Utility Model Publication No. 55-54573).

When the electromagnet 13 is turned on and the electromagnet 13 is energized, the slide sleeve 11 is turned on.
3, the two-type magnet 12 slides to the right in the figure and engages only one of the engaging teeth 32α as shown by the chain line, thereby cutting off the transmission of rotational force and entering the OFF state. Switching of energization to and 13 is performed by a changeover switch 14 that can be operated from the driver's seat, and one changeover switch 14 can turn on and off the clutch mechanisms for both the left and right wheels at the same time.

1 is attracted to the electromagnet 12 as shown by the solid line in FIG. 1, and the clutch is turned on. In this state, the electromagnet 12
Since sliding occurs on one end surface IHi of the slide sleeve 11 as the wheel rotates, it is recommended to provide a layer of a material with a small sliding friction coefficient and excellent wear resistance on the sliding surface portion. Alternatively, it may be difficult to take measures such as interposing a bearing, but as shown in the embodiment shown in FIG. By providing a switching element 16 that automatically cuts off power to the electromagnet 12 in response to a signal, when the clutch-on operation of the slide sleeve 11 is completed, the electromagnet 12 becomes de-energized and loses its attractive force. Reduction in sliding friction between electromagnet 12 and slide sleeve 11 and significant reduction in rotational resistance.

回転抵抗。When the slide sleeve 11 slides and the clutch is turned on, the contact 17 comes into contact with one end surface of the slide sleeve 11 and is grounded from the slide sleeve 11. Therefore, the potential of the contact 17 becomes O, and the switching element 16
is switched to non-conducting state, and the energization to the electromagnet 12 is stopped, and there is no attraction force of the electromagnet 12, and rotation resistance due to the attraction of the electromagnet 12 occurs.

で、工業的価値極めて大なるものである。As described above, according to the present invention, in a part-time 4WD vehicle, the spindle of the wheel that becomes the driven wheel when running in two-wheel drive is divided into two parts, and the two divided spindles are connected by a clutch mechanism operated by an electromagnet. Due to the fact that the electromagnet is configured to be disconnected, it is possible to simultaneously shut off the rotation of the spindle portions of the left and right driven wheels during two-wheel drive simply by switching the changeover switch that switches the energization to the electromagnet. It is possible to stop almost all rotation of the power transmission system on the driven wheel side, reducing running resistance, fuel consumption, and noise. By installing a mechanism that detects when the clutch mechanism is fully engaged and cuts off the power to the electromagnet when the clutch mechanism is turned on, it has significant effects such as significant reductions in rotational resistance, sliding resistance, etc., and power savings. It has enormous industrial value.
