Abstract: An electric drive axle with an electric motor having a motor shaft that is rotatable about an axis, a differential, and a transmission. The transmission transmits rotary power between the motor shaft and the differential. The multi-speed reduction has an input shaft and at least three on-axis gears. The input shaft is rotatably coupled to the motor shaft. Each of the at least three on-axis gears is co-axial with the input shaft and is rotatable relative to the input shaft in at least one of a first speed ratio and a second speed ratio. The input shaft is axially movable along the axis between a first position, in which a first one of the at least three on-axis gears is rotationally coupled to the input shaft, and a second position in which a second one of the at least three on-axis gears is rotationally coupled to the input shaft.

Abstract: An improved master cylinder for use with a hydraulic clutch or hydraulic brake system. The master cylinder has a master cylinder body defining a bore. A piston is configured to slide in the bore when an actuation lever is compressed by a user. Sliding of the piston as a result of the depression of the lever causes the piston to depress a spring and to increase hydraulic pressure in the hydraulic line leading to the brake or clutch. A spring is configured to return the piston when pressure is released from the actuation lever. The master cylinder body in some embodiments is configured for lateral position adjustment relative to a mounting bracket. In some embodiments the master cylinder has a reservoir. The reservoir can be oriented at a tilted angle relative to the body of the master cylinder. In further embodiments the master cylinder has an outlet nut that is configured for attachment to the hydraulic line. The outlet nut is configured such that removal of the outlet nut allows for access to the bore, including the spring and piston.

Abstract: A patient support apparatus includes a base having a length and including a plurality of caster wheels enabling movement of the patient support apparatus across a floor surface. An auxiliary wheel support structure is secured to the base and rotatably supports at least one non-castered auxiliary wheel. A drive mechanism including a motor may be configured to drive the auxiliary wheel. A braking system including at least one brake member may be configured to apply a braking force to decelerate the auxiliary wheel and is movable between a first position wherein the at least one brake member is disengaged from the auxiliary wheel and a deployed position wherein the at least one brake member is frictionally engaged with the auxiliary wheel to restrict rotation of the auxiliary wheel. The braking system may be configured to synchronize the braking forces applied to first and second auxiliary wheels.

Abstract: This electric braking device is provided with: an electric motor MTR that, in accordance with an operation amount Bpa of a braking operation member BP, generates a pressing force Fba, being a force pressing a friction member MSB against a rotary member KTB that rotates integrally with a wheel WHL of the vehicle; and a circuit board KBN to which a processor MPR and a bridge circuit BRG are mounted. The device is further provided with a rotation angle sensor MKA for detecting the rotation angle Mka of the electric motor, and drives the electric motor MTR on the basis of the rotation angle Mka. An end face Mmk of the rotation angle sensor MKA is fixed so as to be in contact with the circuit board KBN. The device is further provided with a pressing force sensor FBA for detecting the pressing force Fba, and drives the electric motor MTR on the basis of the pressing force Fba. An end face Mfb of the pressing force sensor FBA is fixed so as to be in contact with the circuit board KBN.

Abstract: A riding lawn care vehicle (10) includes first and second drive wheels (32), a steering lever (34), a brake assembly (110), and a mechanical brake linkage assembly (120) including a cable tensioner (250). The brake assembly (110) may be operably coupled to at least one of the first and second drive wheels (32) to enable brakes to be selectively applied to the first and second drive wheels (32) based on a position of the steering lever (34). The cable tensioner (250) may be configured to activate the brake assembly (110) relative to the at least one of the first and second drive wheels (32) in response to the steering lever (34) being moved outwardly to an outboard position. The mechanical linkage assembly (120) may be configured to provide a greater amount of rotation of the cable tensioner (250) than a magnitude of rotation of the steering lever (34) when the steering lever (34) is moved from the inboard position to the outboard position.

Abstract: A hydraulic master apparatus for a hydraulic brake or clutch of handlebar-guided vehicles having a handlebar tube includes a support, a lever pivotally connected to the support, a hydraulic cylinder sized to fit in the handlebar tube and having a piston, and a pulling device configured to exert a pulling force on the piston when the lever is actuated. The apparatus also includes a grip width adjusting apparatus, by which a distance between the support for the lever and the hydraulic cylinder is adjusted to adjust a grip width. Also included is a cover that, responsive to being connected in the handlebar tube, defines with the hydraulic cylinder in the handlebar tube a compensating chamber therebetween.
