Problems solved by technology

For medium and large shift transmissions, the volume and weight of the shift fork mechanism are relatively large, and it is difficult to realize the gear shift through the linear motion of the shift lever. Generally, the rotary motion of each shift lever is used to realize the switching between gears. , the interlocking mechanism of the original automobile transmission cannot be applied when the shift lever rotates

Embodiment

[0013] Example: figure 1 As shown, the multi-gear shift mechanical interlock mechanism (taking the four-speed transmission as an example) is mainly composed of a shift seat 1, a shift handle 2, a shift handle 3, a shift fork shaft 4, a shift fork shaft 5, and an interlock Lock disc 6, interlock disc 7, flat key 8, flat key 9, interlock pin 10, travel switch 11, travel switch 12, travel switch 13, travel switch 14 etc. form. (The figure shows the 3 / 4 gear structure, 5 / 6 gear structure, etc. can be deduced by analogy; at the same time, the travel switch is an optional part, through which the corresponding electrical control system can be designed to realize another interlocking method - electrical control interlocking lock, but the present invention involves mechanical interlocking, so the electrical control is not described in this article.) When the transmission is switched to a certain gear position, for example, the shift handle 2 rotates to the left or right, and the shi...

Abstract

A multi-gear shifting mechanical interlocking mechanism mainly comprises two adjacent horizontal shift shafts, wherein one side end of each of the two shift shafts is fixedly connected with a shifting handle; each of the two shift shafts is integrated with respective interlocking disc into a whole through respective flat key; an interlocking pin is mounted between two adjacent interlocking discs; arc grooves for allowing the ends of the interlocking pins to be inserted into are formed at the two ends of each of the two interlocking discs opposite to the interlocking pins; the two interlocking discs and the interlocking pins are all mounted on the same shifting seat; a travel switch is mounted in each of the left and the right shifting directions of each of the two shifting handles. The multi-shift shifting mechanical interlocking gear has the characteristics of simple, rational and compact structure, high convenience in operation, high simplicity in machining and mounting, accurate positioning, high reliability in operation, extremely low failure rate and the like.

Description

technical field [0001] The invention relates to a mechanical shift interlocking mechanism of a multi-gear shift transmission with the number of gears ≥ 3. Background technique [0002] At present, the common shift self-locking mechanism is basically the structure used in automobile transmissions. Due to the small structure and volume of the automobile transmission, the shift fork mechanism is relatively light and handy, and the shift lever basically moves in a straight line when switching gears. Generally, the interlocking pins installed in the housing are used to realize the interlocking between the gears. interlock. For medium and large shift transmissions, the volume and weight of the shift fork mechanism are relatively large, and it is difficult to realize the gear shift through the linear motion of the shift lever. Generally, the rotary motion of each shift lever is used to realize the switching between gears. , the interlocking mechanism of the original automobile tr...
