Embodiment Construction

[0014] As shown in Figure 5, Figure 6 and Figure 7 Shown: the present invention is made up of main shaft 1, secondary shaft 2, first gear driving gear 3, first gear driven gear 4, gear 5, spline gear 6, gear shift slider 7, first-stage double gear 8, bridge gear 9. It consists of a first-stage double gear shaft 10, a bridge gear shaft 11, a washer 12, a first-stage double gear bushing 13 and a bridge gear bushing 14. There is a driving gear 3 on the main shaft 1 and a driving gear 3 on the secondary shaft 2. There is a driven gear 4 and a gear 5, and a spline gear 6 is installed between the gear 5 and the driven gear 4. Its structural features are: A. A shifting gear is arranged at the position corresponding to the gear 5 on the main shaft 1 Slider 7, the shift slider 7 is set on the main shaft 1 through splines and spline grooves; B, one side of the secondary shaft 2 is provided with a first-stage double gear 8 and a bridge gear 9, and the first-stage double gear 8 One ge...

Abstract

In one kind of engine sets at the reverse gear organization, mainly by the main axle 1, countershaft 21 shopkeepers moves the gear 31 grades of driven gears 4, the gear 5, spline the gear 6, changes the files slide 7, level of doubles bond gears 8 levels of idle wheels 9 and so on the constitution, the main axle on 1 has a shopkeeper to move gear 3, countershaft on 2 has grade of driven gears 4 and the gear 5, between 4 installs on the gear with grade of driven gears has spline the gear 6, its structure characteristic lies in: On 1 has in the main axle with the gear 5 correspondences position establishments changes the files slide 7, the change files slide 7 passes spline and the flowered key slot coverall in the main axle on 1; Has level of double joint gears in countershaft a 2 side establishment 8 and the idle wheel 9, a level of double joint gears 8 gear 4 meshes to grade of driven gears, another gear and the idle wheel 9 mesh, the idle wheel at the same time 9 5 meshes with the gear. This invention intensity good, various grade of velocity ratios more reasonable, cost low, the installment is convenient.

Description

technical field [0001] The invention relates to a reverse gear mechanism, in particular to an engine built-in reverse gear mechanism. Background technique [0002] The traditional engine reverse gear mechanism has two structural types: external and internal. External means that the reverse gear mechanism is arranged outside the engine. There is no reverse gear on the main shaft 1 and auxiliary shaft 2 in the engine. The main shaft 1 and auxiliary shaft 2 A rotatable (fourth gear driven) gear 5 (such as figure 1 As shown), the installation and use of the reverse gear mechanism are inconvenient, and the cost is relatively high. In order to realize that the reverse gear mechanism is built-in, someone changes the second gear of the engine into a reverse gear through a bridge gear 15, and the reverse gear driving gear 16, the reverse gear driven gear 17 and the bridge gear 15 are on the same plane (such as image 3 As shown), due to the structural limi...
