Abstract
A work vehicle including an engine and a transmission operatively engaging the engine. The transmission has at least one input shaft and at least one output shaft, wherein a ratio of a rotational speed of the output shaft with respect to a rotational speed of the input shaft may be changed by said transmission. The work vehicle further includes a cutter drum operatively engaging said transmission and a controller, wherein the controller selects the transmission ratio based on an input of a user of the work vehicle.
Claims31
A work vehicle adapted for use in pavement removing operations comprising:
- a self propelled chassis;
- an engine mounted to said chassis;
- a transmission operatively engaging said engine, said transmission having at least one input shaft driven by said engine and at least one output shaft, wherein a ratio of a rotational speed of said output shaft with respect to a rotational speed of said input shaft may be selectively changed in said transmission;
- a cutter drum having a plurality of cutter teeth located around the outer periphery of said drum, said cutter drum operatively engaging said output shaft of said transmission, wherein a rotational speed of said cutter drum is proportional to the rotational speed of said output shaft of said transmission;
- a controller connected to said transmission, wherein said controller selects said ratio in said transmission based on an input of a user of said work vehicle.
A work vehicle comprising:
- an engine;
- a first transmission engaging said engine, said transmission having a plurality of input/output ratios;
- a cutter drum connected to said first transmission;
- a second transmission connected to said engine, wherein the output of said second transmission is directly proportional to the groundspeed of said work vehicle;
- a controller, wherein said controller selects the ratio of said transmissions based on the input of a user of said work vehicle, wherein said controller is selectively placeable in a manual or automatic mode based on the input of said user.
A work vehicle comprising:
- an engine;
- a first transmission connected to said engine, said transmission having a plurality of input/output ratios;
- a cutter drum connected to said transmission;
- a hydrostatic transmission connected to said engine, wherein the output of said transmission is directly proportional to the groundspeed of said work vehicle, and wherein said transmission drives a plurality of wheels or crawler tracks;
- an electronic controller, wherein said controller selects the ratio of said first transmission based on the input of a user of said work vehicle, wherein said controller is selectively placeable in a manual or automatic mode based on the input of said user, wherein in said manual mode said controller maintains a ratio between a speed of said engine and a speed of said cutter drum, and in said automatic mode said controller maintains desired requirements by selecting a ratio in said transmission;
- a keypad mounted on said vehicle and connected to or integrated as a part of said electronic controller by which said user may effectuate said inputs.
