Gearbox device for vehicle

Abstract

The present invention relates to a gear-box device for car. It is characterized by that a first slide block is set on the main shaft in the gear-box interior, one side of said first slide block is equipped with forward gear, step-up gear and gear, a second slide block is set on the couple axle, and on the couple axle of one side of said second slide block a reverse gear is set, and on the couple axle of another side of said second slide block a step-up couple gear, a forward couple gear and a driving bevel gear are set, and in the driving bevel gear place a final shaft for making shaft transmission is set, and a containing space for mounting said final shaft group is formed on said gear-box cover, so that said driving bevel gear and driven bevel gear on the final shaft group can be meshed and coupled.

Description

【Technical field】 [0001] The invention relates to a transmission device for a vehicle. 【Background technique】 [0002] Known gearbox device, please refer to shown in Fig. 1, and this gearbox 10 mainly transmits the power of an engine to a driven shaft 11 via a belt speed change mechanism (not shown here), and the driven shaft 11 A transmission gear 111 integrally formed on it is used for mutual meshing transmission with a first gear 121 on a connecting shaft 12 set up on the side, and the first gears 121 are respectively arranged on the connecting shaft 12 in sequence , a reverse slide block 122, a reverse bevel gear 124, a second gear 125, a third gear 126, a forward bevel gear 127 and a fourth gear 128, wherein the reverse slide block 122 and The reverse bevel gear 124 is respectively provided with an embedding groove 123, 123', and the reverse slider 122 is engaged with the linkage shaft 12 through a toothed part (not shown in the figure) on it. , so that when the inter...

Problems solved by technology

[0009] In view of the in-depth introduction in the above-mentioned background technology, it is not difficult to know that the conventional transmission device has the disadvantage that the tooth backlash adjustment is not easy. If the tooth backlash adjustment is inaccurate, it will cause serious transmission noise. In addition, the use of a C The clamp positions the final shaft group between the gearbox cover and the outer cover of the gearbox. In addition to poor positioning accuracy, it will also make it difficult to adjust the backlash of the teeth. If the backlash adjustment is not accurate, it will cause transmission noise. There will be situations where assembly is not easy; therefore, the purpose of the present invention is to provide a transmission device for vehicles, which can effectively solve the problem that the backlash adjustment of bevel gears in existing transmissions is difficult, and at the same time achieve maintenance and assembly. Ease of use and the effect of reducing the number of parts
