A cable structure for clutch control of a mechanical automatic transmission

Abstract

The invention discloses an inhaul cable structure for clutch control of a mechanical automatic transmission. The inhaul cable structure comprises an inhaul cable steel wire, an inhaul cable lead screw and a shift fork groove, wherein the inhaul cable lead screw is connected with one end of the inhaul cable steel wire and is fixed through a locking mechanism arranged outside the inhaul cable lead screw in a sleeving mode, and the inhaul cable steel wire is installed in the shift fork groove through a notch of the shift fork groove. The inhaul cable structure further comprises a limiting mechanism used for limiting the locking mechanism to rotate in the shifting fork groove. An existing inhaul cable structure is replaced by adding a limiting boss through an inhaul cable locking nut, the swinging angle of the inhaul cable can be controlled within a certain range, jamming of the locking nut during movement in the transmission shifting fork groove is avoided, the length of the inhaul cable is increased, and the swinging angle during movement is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile clutch systems, and in particular relates to a cable structure for clutch control of a mechanical automatic transmission. Background technique [0002] In the existing technical solution, the steel wire part of the EMT clutch cable of the gearbox is too short, and the tensile stress and bending stress are too concentrated during use. At the same time, the swing angle of the existing cable structure is too large, and the steel wire structure cannot meet the larger swing corners, resulting in a risk of cable breakage. [0003] Since there is a gap of 5 mm between the cable lock nut and the end face of the gearbox shift fork, the lock nut has no limit in the gearbox shift fork groove during the actual movement, resulting in uncontrollable movement range of the lock nut, resulting in the lock nut being in the There may be a phenomenon of jamming in the fork slot.
