Example Embodiment

[0023] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0024] See figure 1 , A self-interlocking mechanism of a barrel-type housing transmission, comprising a shift fork 1', a shift fork shaft 2', a guide block 4'and a cylindrical pin 5', wherein the guide block 4'is fixed in the pull-out mechanism by the cylindrical pin 5' The fork shaft 2'is to prevent relative movement with the fork shaft 2'. The guide block 4'can move axially and slidably fit with the cylindrical housing with a circumferential limit, so that after the mechanism is installed in place, it can prevent pulling out The rotation of the fork shaft.

Abstract

The invention relates to a self-locking and interlocking mechanism for a cylindrical shell speed changer. The self-locking and interlocking mechanism comprises a shifting fork (1'), a shifting fork shaft (2'), a guide block (4'), a cylindrical pin (5'), a pressurizer, steel balls and a signal switch (10), wherein the guide block (4') acts on a cylindrical shell to limit the rotation of the cylindrical shell, and is fixed to the shifting fork shaft (2') by the cylindrical pin (5') to prevent the shifting fork shaft (2') from rotating; a tangent plane is positioned on the surface of the shifting fork shaft (2'), so that the shifting fork shaft is convenient to install; the shifting fork is connected with the shifting fork shaft by an elastic retainer ring (3'), so that the shifting fork shaft can rotate after being installed; the shifting fork shaft comprises a plurality of locking grooves and movable pins; and the movable pins are used for pushing the steel balls accommodated in the locking grooves out of the grooves to lock or unlock the shifting fork shaft. The self-locking and interlocking mechanism can be convenient to produce while the using performance is ensured by combining the advantage of a classical simple and reliable self-locking and interlocking mechanism for the steel balls and the advantages of light quality and convenience for batch production of aluminum alloy cylindrical shells.

Description

technical field [0001] The invention relates to the field of automobile transmissions, in particular to a self-interlocking mechanism of a barrel case transmission. Background technique [0002] The classic transmission steel ball self-interlocking mechanism is widely used in the transmission control mechanism due to its simplicity, reliability and low cost. However, the classic transmission steel ball self-interlocking mechanism can only be applied to the transmission of the box-type case because the steel ball assembly and the shift fork shaft can be assembled separately. However, for the lightweight aluminum alloy cylindrical shells widely used today, due to the batch casting and structural strength of the aluminum alloy shells, the aluminum alloy shells must be cylindrical shells to facilitate casting and drafting. For the aluminum alloy cylindrical shell, the gear, shaft, and shift fork mechanism cannot be assembled separately, but can only be assembled as a whole. Th...
