Induced current utilization type differential limit device

Abstract

To provide an induced current utilization type differential limit device with a simple structure using electromagnetic induction without employing complex electronic or mechanical control.SOLUTION: A mechanism can be completed by an internal mechanism in which an electromagnetic induction device is installed between a differential case of a differential device and a one-side gear shaft, and when there is an excessive difference in rotation between right and left side gear shafts, the electromagnetic induction device acts as a differential limit device. In order to achieve even greater differential limiting, an electric braking device is installed in the side gear shaft and the differential case to pass the current generated by the electromagnetic induction device.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a limited slip differential with a high performance and simple system. [Background technology]

[0002] Conventional limited slip differentials have mechanical components that are prone to wear and require complex gear configurations, while electronically controlled systems have complex control systems. DISCLOSURE OF THE INVENTION

[0003] This has resulted in the following problems: (a) Depending on the structure, the manufacturing cost of the differential limiting device may be high. (b) The need for maintenance is greater than with a differential without a limited differential. (c) It is sometimes difficult to quickly control the rotational fluctuations on both shafts of the differential limiting device actuator. The present invention has been made to solve this problem.

[0004] The invention provides an electromagnetic induction device that operates by the difference in rotation between the left and right side gears of the differential, and uses the current generated by this to suppress the difference in rotation between the side gear shafts.

[0005] This is a limited slip differential device that does not require any complicated peripheral equipment compared to conventional limited slip differential devices, is maintenance-free, and is easy for the general public to use. BEST MODE FOR CARRYING OUT THE INVENTION

[0006] Hereinafter, an embodiment of the present invention will be described. (i) An electromagnetic induction device (3) is installed between the differential case (1) of the differential device and the left side gear shaft (2). (b) A large resistor is provided to create a circuit to pass the current generated in (a), and the electromagnetic induction device (3) is used as an operation limiting device (5). (c) Using the current generated in (a), an electric braking device (4) such as a powder clutch is installed on the extension side of the differential case (1) on the left side gear shaft (2) as an additional differential limiting device (5). The present invention has the above-described configuration. [Brief explanation of the drawings]

Claims

[Claim 1] An induced current type differential limiting device that has a device that uses an electromagnetic induction device as a brake and installs it on the differential case or side gear shaft to limit the differential when an excessive rotation difference occurs between the left and right side gear shafts of the differential device. In addition, an induced current utilization type differential limiting device also employs a method in which the current generated by the electromagnetic induction device is passed through an electric braking device such as a powder clutch as an even larger resistance device, thereby limiting the unnecessary difference in rotation between the left and right side gear shafts.
