Patent number: 10871178Abstract: A transaxle includes a braking unit disposed in the transaxle casing, the braking unit configured to brake the axle. The braking unit includes an operating shaft projecting from one side of the transaxle casing. A link mechanism of the transaxle is includes a relay arm rotatably pivoted on a shaft provided on the one side of the transaxle casing, a brake arm fixed to the operating shaft, the brake arm being configured to rotate between a braking position and an unbraking position of the braking unit together with the operating shaft, a first link configured to manipulate the relay arm, and a second link configured to join the relay arm to the brake arm. The link mechanism constrains motion of the brake arm through the second link such that an external force on the braking unit cannot cause an unexpected release from the braking state.Type: GrantFiled: March 25, 2019Date of Patent: December 22, 2020Assignee: Kanzaki Kokyukoki Mfg.
