Gearbox and vehicle

Abstract

The invention relates to a manual gearbox and a vehicle including the same. The manual gearbox comprises an input shaft connected with an engine, an output shaft selectively engaged to the input shaft through a blockage gear, and a reverse gear shaft parallel to the input shaft, wherein the input shaft is connected with a forward gear driving gear and a reverse gear driving gear; the output shaft is connected with a forward gear driven gear; synchronizers are arranged between every two forward gear pairs; a low-gear synchronizer gear sleeve is connected with a reverse gear driven gear; and a reverse gear idle wheel is arranged on the reverse gear shaft, and can forwards and backwards slide to be joined with the reverse gear driving gear and the reverse gear driven gear. The manual gearbox has the advantages of compact arrangement, low cost, light weight and high strength, satisfies the customer needs in gear shifting quality and noise level, and guarantees the maximal compatibility with an existing production process.

Description

technical field [0001] The present invention relates to the technical field of automobile gearboxes; more specifically, the present invention relates to a manual gearbox, and further relates to an automobile including such a manual gearbox. Background technique [0002] The development of China's auto industry has always been oriented by customer needs, and manual transmissions have always occupied half of the auto market by virtue of their cost advantages. With the development of the times, on the one hand, users have higher and higher requirements for vehicle power performance; on the other hand, the increasingly severe energy problems have caused customers to pay more attention to vehicle fuel consumption. [0003] In order to balance the contradiction between vehicle power and economy, it is necessary to increase the number of gears of vehicles equipped with manual transmissions, so that the power output of the engine can be kept in a more economical working condition. ...

AI Technical Summary

Problems solved by technology

[0004] Due to the space limitation of the front cabin layout of the car, the manual gearbox has been increased from five speeds to six speeds. If a new structure is not adopted, it will inevitably bring about problems such as difficult space layout of the vehicle, excessive weight increase, and insufficient structural rigidity.

At present, vehicles equipped with six-speed manual transmission are generally aimed at high-torque engines. Problems such as large radial size of the box, complex part constraints, high cost, and serious noise and vibration

[0005] For example, the Chinese patent "Double Output Shaft Transmission (Notice No.: CN2799978; Announcement Date: July 26, 2006)" discloses a dual output shaft transmission, which includes an input shaft assembly and two output shaft assemblies. The radial size of the box is large, the weight and cost are high, and the noise and vibration performance is poor. At the same time, a dual-mass flywheel is required to reduce the noise problem when integrated into the powertrain, which will inevitably increase the assembly space and cost.
