Embodiment Construction

[0022] Preferred embodiments of the present invention will now be described in detail, an example of which is illustrated in the accompanying drawings.

[0023] Figure 1-3 A drive assembly 10 is shown comprising a drive part 11 , a driven part 12 and optionally a connector 20 connecting the drive part 11 with the driven part 12 . The drive member 11 may be a shaft connected to a lawnmower motor (not shown). The driven member 12 may be a blade holder adapted to carry a lawnmower blade (not shown).

[0024] The key 13 secures the drive hub 14 on the drive part 11 in the usual manner. The power take-off pulley 15 is connected to the drive member 11 in a conventional manner. A bearing assembly 16 mounts the driven part 12 on the drive part 11 . The bearing is held axially on the drive part 11 between flanged bolts 17 fixed to the drive part 11 and the drive hub 14 . Bearing assembly 16 enables rotation of drive member 11 relative to driven member 12, as will be described lat...

Abstract

A friction coupling includes a friction member including a brake surface and a clutch surface in a different plane from the brake surface; a spring abutting the friction member; a brake member proximate to the brake surface; the brake member mounted relative to the friction member to permit relative rotation; and a brake actuator connected to the brake member.

Description

technical field [0001] The present invention relates to power equipment, including but not limited to lawn mowers, tillers, snow blowers, and tractors. In particular, the invention relates to blade brakes and clutches for power equipment. Background technique [0002] Common powered equipment includes a clutch that selectively engages the lawn mower blades with an output member of the engine. A brake may also be included which will decelerate the rotation of the mower blade when the mower blade is disengaged from the engine output. The combination of these two connectors allows the operator to control the motion of the mower blades independently of the engine output components. [0003] Typically, the components used in clutches are separate and distinct from those employed in brakes. This configuration produces a large number of parts for assembly as well as parts for replacement during routine maintenance. Routine maintenance is also hindered by the need to disassemble ...
