<p>A gear shift structure of a vehicle gearbox and a gearbox. The gear shift structure comprises a transmission shaft (1). A locking block pressure plate (2), a driven plate (3), and a driving gear (4) are successively sleeved on the transmission shaft (1). Both the locking block pressure plate (2) and the driving gear (4) are sleeved on the transmission shaft (1) in a free mode, and the locking block pressure plate (2) is capable of axially sliding along the transmission shaft (1). The driven plate (3) is fixedly connected to the transmission shaft (1) to implement synchronous rotation. Several groups of cylindrical locking blocks (5) extending into penetrating holes of the driven plate are fixedly disposed on an end surface of one side, close to the driven plate (3), of the locking block pressure plate (2). Several groove holes (6) facilitating penetrating of the cylindrical locking blocks are disposed at corresponding positions of the driving gear (4). Gear shifting fork rings (7) used for pushing the locking block pressure plate (2) to slide are disposed at the other end side of the locking block pressure plate (2). A reset spring (8) is disposed between the locking block pressure plate (2) and an end surface of the driven plate.</p> |
