Abstract: The present invention relates to a method for determining the rotational speed of the main shaft (3) of a transmission in which the main shaft (3) is connected to an output shaft (4) via a shiftable planetary gear (17), whereby the main shaft (3) is connected in a rotationally fixed manner to the sun gear (18) and the output shaft (4) is connected in a rotationally fixed manner to the planet carrier (20). The steps of the method are picking up the rotational speed (nHohlrad) of the ring gear (22), picking up the rotational speed (nAbtrieb) of the output shaft or the planet carrier (20), and computing the rotational speed (nHauptwelle) of the main shaft (3) from the rotational speed (nHohlrad) of the ring gear and the rotational speed (nAbtrieb) of the output shaft or the planet carrier (20). The present invention further relates to a transmission having a rotational speed pickup device.

Abstract: A speedometer drive arrangement particularly suitable for use in snowmobiles is readily convertible to give a readout that is in Mph or Kph, while providing only a single scale on the face of the instrument. The change is effected by the interposition of a small geared drive immediately between the rear of the speedometer instrument and the input of the cable drive.

Abstract: A brake for a vehicle adapted to be used for an off-road 3-wheel motor cycle or 4-wheel vehicle. This brake has a wheel, an axle rotated integrally with the wheel, a cylindrical hub rotatably engaged with the axle, a chamber formed in the hub and a multi-disc brake provided in the chamber. Thus, the brake is hardly affected by the influence of sand, mud and water scattered when the vehicle is running, and the tires and wheels can be readily cleaned when the vehicle is cleaned.

Abstract: A two piece dirigible wheel of an automotive vehicle has its steering axis on the vertical center line of the wheel, and a brake disc is supported along the inner periphery of the wheel with annular braking surfaces in vertical planes adjacent to the center line and engaged by caliper type brake shoes.

Abstract: This invention is a devise which when installed into its monitoring location in conjunction with vehicles transmission, shall increase the rotation of the speedometer cable and as a result, speedometer dials and odometers indicating speed and distance in miles shall automatically correct readings to be in kilometers without the changing or modifying in anyway existing vehicle speedometer dials. Removal of the devise, permits dials to again be read in miles. Installation and removal are very simple.
