This invention relates to a throttle grip housing assembly for a motor vehicle, such as, two wheelers and three wheelers.

The known throttle grip housing assembly consists of a plastic throttle housing which is secured at the switch assembly on one side. The throttle grip is mounted on this housing.
There is an annular gap between the handle tube and the plastic throttle housing. As a result of this gap the housing contacts the tube unevenly all along its length as a result of which there is a radial movement of the housing about the handle bar axis. Due to this movement vibration felt by the rider on the right side of the handlebar is more, whereas on the left side the handle grip is directly glued to the handle tube leaving no gap. Therefore, the vibration felt on the left is less compared to the right side. The annular gap on the right side is necessary for normal throttle operation. If this gap is reduced the throttle operation becomes hard.

The present invention overcomes this problem by maintaining the annular gap as well as reducing the radial movement of the plastic throttle housing,
The advantages of this invention are:

1. The radial movement of plastic housing is reduced

2. Uneven rubbing of plastic throttle housing on handle tube is prevented

3. Plastic housing is supported at both ends

4. Since the rubbing and the radial movement is avoided the vibration felt on the handle by the rider is reduced

The throttle grip housing assembly for a motor vehicle, according to this invention, comprises a housing, the first end of which is located at the switch assembly of the vehicle; a spacer one end of which is clamped on the surface of a welded spacer in the said tube; a damper mass on the surface of which the other end of the spacer rests, characterised in that the second end of the housing accommodates a supporting member forming a snug fit in the said housing, the said supporting member having a central hole for receiving the spacer in a close sliding fit, such that when the damper screw of the damper mass is tightened, there is no uneven rubbing of the said housing on the said tube.

This invention will now be described with reference to the accompanying drawings which illustrate, by way of example, and not by way of limitation, possible embodiments of the throttle grip housing assembly proposed herein.

The first end a plastic housing 1 is located at the switch assembly of the vehicle. One end of a spacer 2 is clamped on the surface of a welded spacer 9 in the handle tube. On the surface of the damper mass 5 the other end of the spacer 2 rests.

The second end of the housing 1 accommodates a supporting member 4 forming a snug fit in the said housing, the said supporting member having a central hole for receiving the spacer 2 in a close sliding fit, such that when the damper screw of the damper mass is tightened, there is no uneven rubbing of the said housing on the said tube.

The supporting member will be a metallic or non-metallic bush. In the embodiment illustrated the supporting member 4 is a nylon bush. The supporting member can also take on any other form to serve its purpose, such as, a bearing. The said member can be integral or non-integral with the housing as shown in Fig.2.

Referring to this Figure an integrated bush with the housing can be explained as in place of the nylon bushes. A bush is integrated with the housing frame which serves the same purpose.

It will be appreciated that various other embodiments are possible without departing from the scope and ambit of this invention.
