DESC:FIELD
The present disclosure relates to mechanical engineering. More specifically, the present disclosure relates to vehicles.

DEFINITION(S)
The expression “crankcase LH” referred to in this disclosure, refers to left hand side of a crankcase utilized to house a crankcase assembly of a vehicle.

This definition is in addition to those expressed in the art.

BACKGROUND
A wire harness is used in a two wheeled vehicle, hereinafter referred to as a vehicle, to transmit signals or electrical power to various units of the vehicle. A wire harness is a system of insulated conducting wires bound together by means of insulated material.

Conventionally, for securing a neutral wire harness on the crankcase LH, separate lugs are provided within a magneto cover of an engine of the vehicle. Due to the disposition of the neutral wire harness into the lug, it becomes necessary to pull the wires/cables from the magneto cover at the time of servicing the vehicle. Due to pulling of wires/cables, the time required for servicing the vehicle increases considerably, thereby causing inconvenience to users. Further, pulling of the wires/cables may damage the wires/cables or the lugs holding the wire or the cables, thereby requiring frequent maintenance. Further, due to an arrangement of the lugs in the magneto cover, the required length of the wire harness increases as the wire has to be bent to conform to the position of the lugs, thereby increasing installation and designing cost of the wire harness as well as of the vehicle. Furthermore, additional brackets are required along with the lugs for holding the wire harness.

Hence, there is a need for a crankcase which easily secures a neutral wire harness routing and thereby alleviates the drawbacks associated with the conventional neutral wire harness.

OBJECTS
Some of the objects of the arrangement of the present disclosure are aimed to ameliorate one or more problems or to at least provide a useful alternative are listed herein below.

An object of the present disclosure is to provide a crankcase of a vehicle for routing a wire harness that requires comparatively lesser components for securing and routing a wire harness.

Another object of the present disclosure is to provide a crankcase of a vehicle for routing a wire harness that along with wire harnessing facilitates protection to a neutral gear indicator of a vehicle.

Another object of the present disclosure is to provide a crankcase of a vehicle for routing a wire harness that facilitates routing of the wire harness such that the routing facilitates reduction in service time of a vehicle.
Another object of the present disclosure is to provide a crankcase of a vehicle for routing a wire harness that has a comparatively smaller path for routing of the wire harness and hence requires a comparatively shorter length of wire harness.

Other objects and advantages of the present disclosure will be more apparent from the following description when read in conjunction with the accompanying figures, which are not intended to limit the scope of the present disclosure.

SUMMARY
The present disclosure discloses a vehicle crankcase, typically a crankcase LH, for routing a wire harness. The vehicle crankcase comprises a first rib, a second rib and a third rib. The first rib is configured with a first recess. The first rib extends upright from an operative inner surface of the crankcase and is disposed in an operative bottom portion of the crankcase. The first recess routes a first portion of the wire harness connected to a neutral gear indicator. The second rib extends upright from the operative inner surface of the crankcase and is disposed concentric and proximate to a first opening, which is configured on the crankcase for receiving an output shaft, to form a cavity between the second rib and the first opening. The cavity routes a substantially middle portion of the wire harness. The third rib is configured with a second recess. The third rib extends upright from the operative inner surface of the crankcase and is disposed in an operative top portion of the crankcase. The second recess routes a second portion of the wire harness, which further extends outside the crankcase.

DETAILED DESCRIPTION
A crankcase of a vehicle for routing a wire harness of the present disclosure will now be described with reference to the embodiments shown in the accompanying drawings. The embodiments do not limit the scope and ambit of the disclosure. The description relates purely to the examples and preferred embodiments of the disclosed method and its suggested applications.

The crankcase of a vehicle for routing the wire harness herein and the various features and advantageous details thereof are explained with reference to the non-limiting embodiments in the following description. Descriptions of well-known parameters and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.

In accordance with one embodiment of the present disclosure and as illustrated in Figure 1 to Figure 3, a crankcase 100 for a vehicle for routing a wire harness, typically a two wheeled vehicle, is disclosed. The crankcase 100 is a crankcase LH. The crankcase 100 routes a wire harness 10. The crankcase 100 comprises a first rib 20, a second rib 30 and a third rib 40.

The wire harness 10 has a first portion 10a, a substantially middle portion 10b and a second portion 10c. The first portion 10a is disposed in an operative bottom portion 100a of the crankcase 100. The first portion 10a has a first end 10d. The first end 10d is connected to a neutral gear indicator (not shown in Figures) disposed on a receptacle 100d configured on the operative bottom portion 100a of the crankcase 100 for receiving the neutral gear indicator. The substantially middle portion 10b of the wire harness 10 is disposed in a substantially middle portion 100b of the crankcase 100. The second portion 10c is disposed in an operative top portion 100c of the crankcase 100. The second portion 10c has a second end 10e. The second end 10e extends outside the crankcase 100.

The first rib 20, the second rib 30 and the third rib 40 extend upright from an operative inner surface 100e of the crankcase 100. The first rib 20 is located in the operative bottom portion 100a of the crankcase 100. The first rib 20 also protects the neutral gear indicator from external damages. The first rib 20 has a first recess 20a that routes the first portion 10a of the wire harness 10. The first recess 20a has a first grommet (not illustrated in Figures) through which the first portion 10a of the wire harness 10 is routed.

The second rib 30 is located in the substantially middle portion 100b of the crankcase 100. More specifically, the second rib 30 is disposed proximate and concentric to a first opening 50 which is configured in the substantially middle portion 100b of the crankcase 100. The first opening 50 is used for receiving an output shaft (not illustrated in Figures) with an oil seal 52 and an oil seal stopper 53 is configured in the crankcase 100. The second rib 40 and the first opening 50 form a cavity 56 which routes the substantially middle portion 10b of the wire harness 10. In one embodiment as illustrated in Figure 4 and Figure 5, the oil seal stopper 53 is used to secure the substantially middle portion 10b of the wire harness 10 in the cavity 56. In another embodiment as illustrated in Figure 6, a securing stopper 58 is used that secures the substantially middle portion 10b of the wire harness 10 in the cavity 56.

The third rib 40 is located in the operative top portion 100c of the crankcase 100. The third rib 40 has a second recess 40a that routes the second portion 10c of the wire harness 10. The second recess 40a has a second grommet (not illustrated in Figures) through which the second portion 10c of the wire harness 10 is routed.

The first rib 20, the second rib 30 and the third rib 40 thus provide routing of the wire harness 10. The first recess 20a, the cavity 56 and the second recess 40a eliminate the need of pulling the wire harness 10 during servicing, which enables reduction of the time required for servicing of the vehicle. Also, the first rib 20, the second rib 30 and the third rib 40 eliminate the need of lugs used conventionally. Elimination of lugs reduces the number of components to be used for routing as well as the time required for servicing of the engine.

Also, as the wire harness 10 is disposed in proximity of the first opening 50 which receives the output shaft (not illustrated in Figures) with the oil seal, the output shaft (not illustrated in Figures) with the oil seal thus does not obstruct handling of the wire harness 10. The routing of the wire harness 10 has a comparatively smaller path than the conventional path and hence a comparatively smaller length of wire harness 10 is required.
