Problems solved by technology

Clutch engagement and disengagement by the vehicle operator too slowly, or by resting the foot on the clutch pedal to prevent full engagement of the clutch, will cause excessive wear on the clutch surfaces, which can significantly shorten the life of the clutch
A downshift that skips a gear (i.e., a fourth to second downshift, or a fourth to first gear downshift) can result in a sharp increase in the speed of the clutch disc, which can damage the clutch disc, and also shorten the life of the clutch disc

Embodiment Construction

[0062] The following description is merely exemplary in nature and is not intended to limit the invention, its application or uses.

[0063] refer to figure 1 and figure 2 , a clutch protection device for a manual transmission is illustrated and generally designated by the reference number 10 . The clutch protection device 10 is associated with a manual transmission 12 having a housing 14 that supports, positions and protects various components of the transmission 12 , including the clutch protection device 10 . The transmission 12 includes a main multi-plate clutch 16 , a transmission input shaft 22 and a transmission output shaft 24 , wherein the main multi-plate clutch 16 is operatively disposed between a motor such as a gasoline, flex-fuel or diesel engine or a hybrid or electric device. between the output shaft 18 of a prime mover 20 and the transmission input shaft 22 .

[0064] The transmission 12 also includes a shift lever 26 that extends into the vehicle passenge...

Abstract

A manual transmission clutch protection apparatus includes a shift gate cylinder acted upon by the operator controlled shift lever having a first shift pattern that represents all possible shift positions and two or more additional but limited shift patterns corresponding to certain gears which limit the gears selectable and enagageable by the vehicle operator. Two or more actuators which may be solenoids or other electric, hydraulic or pneumatic actuators translate blocking pins or plungers into the additional or limited shift patterns to lockout or block motion of the shift lever and shift gate cylinder into certain gears. Engine speed and temperature sensors, a vehicle speed sensor and a current gear sensor provide data which is utilized to compute which gears, under current sensed operating conditions, should be locked out, that is, unavailable for selection by the vehicle operator.

Description

technical field [0001] The present invention relates to a clutch for a manual transmission of a motor vehicle, in particular to a speed limiting device for a clutch of a manual transmission of a motor vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0003] Although no longer the most popular choice in consumer motor vehicles (passenger cars, sport utility vehicles, and light trucks), manual transmissions and clutches were initially, and for many years, the only powertrain speed and torque matching components available . Nonetheless, for some uses and for some consumers, manual transmissions and manual clutches are the preferred speed and torque matching components. The absolute and positive control over the vehicle powertrain, generally better fuel economy and operating freedom afforded by such components has not been replicated in even th...
