Differential assembly and speed sensor mounting arrangement therefor

A vehicle, comprising:

• right and left driven ground engaging members;
• an engine for providing motive power for driving the right and left driven ground engaging members;
• a drive member rotatably driven by the engine;
• right and left drive shafts coupled, respectively, to the right and left driven ground engaging members;
• a differential operatively connected to the drive member and to right and left drive shafts for proportioning the motive power from the engine between the right and left driven ground engaging members, the differential including a ring gear operatively engaged to the drive member and a differential housing integrally formed or nonrotatably mounted to the ring gear;
• a first speed sensor arranged to measure rotational speed of the left drive shaft;
• and
• a second speed sensor arranged to measure rotational speed of the right drive shaft,
• wherein the differential includes a casing in which each of the ring gear and differential housing is housed, a separate left pulsar ring nonrotatably coupled to a radially inward step portion defined in an end portion the left drive shaft distal from the left driven ground engaging member, and a separate right pulsar ring nonrotatably coupled to a radially inward step portion defined in an end portion of the right drive shaft distal from the right driven ground engaging member, wherein each of the left pulsar ring and right pulsar ring are positioned in a space defined by the casing, each respective step portion of the left drive shaft and right drive shaft and the differential housing, wherein a distal end portion of the drive member faces the step portion of one of the left drive shaft and right drive shaft.
