torque converter continuously variable transmission

Abstract

The invention relates to a mechanical speed-changing device, in particular to a variable torque type continuously variable transmission. The variable torque type continuously variable transmission realizes infinitely variable speed by changing torque of a speed-changing wheel through a speed-changing control rod. The working principle of the variable torque type continuously variable transmission is that a sliding block with a short shaft is mounted in a groove, in the radial direction, of a speed-changing wheel in the box; an eccentric shaft of a power wheel is connected with the short shaft of the sliding block through a transmission rod; a speed-changing control rod can control movement of the sliding block; the torque of the speed-changing wheel is changed through movement of the sliding block, so that the amplitude of the reciprocating rotation of the speed-changing wheel is changed and the reciprocating stroke of a rack meshed with the speed-changing wheel is changed; the reciprocating motion of the rack is transformed into homodromous rotation by a reversing wheel internally provided with an overrunning clutch; power is output through an output shaft. The radial groove of the speed-changing wheel also can lock the sliding block through isometric pin holes to form speed change with gears. The variable torque type continuously variable transmission is stable in process, large in transmission and suitable for speed change of a main shaft of an engine.

Description

technical field [0001] The invention relates to a mechanical speed change device, in particular to a torque converter continuously variable speed changer. Background technique [0002] At present, purely mechanical continuously variable transmissions include friction type and pulsation type. The friction type has the disadvantage of slow acceleration response due to metal belt slippage, and the pulsation type has the disadvantage of power loss. A mechanically rigid continuously variable transmission is missing. Contents of the invention [0003] The purpose of the present invention is to provide a fully mechanical continuously variable transmission, which can realize stepless speed change by pushing and pulling a gear lever, and can realize a large transmission ratio. [0004] The technical solution of the present invention is: install power input wheel, speed change wheel, slide block with short shaft, transmission connecting rod, double-sided rack, reversing wheel, over...
