Forward, reverse and boosting integrated speed variator of motor vehicle

Abstract

The invention discloses an integrated transmission for forwarding, reversing gear and accelerating of a motor vehicle, comprising a power input shaft, an intermediate shaft and a power output shaft, wherein the power input shaft is matched with the intermediate shaft through a transmission device, the intermediate shaft is provided with a gear shifter which is further provided with an accelerating driving gear and a forwarding driving gear at two sides, wherein the accelerating driving gear and the forwarding driving gear are combined with the gear shifter and matched with the intermediate shaft in a transmission way, the middle shift of the gear shifter is a revere gear, the reversing driving gear is matched with the gear shifter and engaged with a driven gear through a reversing intermediate gear which is arranged on the reversing shaft, and the forwarding driving gear and the accelerating driving gear are respectively engaged with the driven gear and accelerating driven gear on thepower output shaft. The invention integrates the acceleration, gear reversing and fast shift to shorten a stress application and reversing transmission chain, reduce the power consumption, increase the mechanical efficiency, and reduce installation and maintenance with compact structure, and the invention changes the current arrangement and improves the rationality of transmission design and arrangement of such vehicles.

Description

technical field [0001] The invention relates to a motor vehicle component, in particular to a forward gear, reverse gear and afterburner integrated transmission for the motor vehicle. Background technique [0002] Small motor vehicles such as three-wheeled motorcycles and miniature four-wheeled agricultural vehicles are widely used because of their lightness and flexibility. In the prior art, the reverse gear of a small motor vehicle generally adopts an assembly structure installed on the engine transmission, and transmits power through the auxiliary shaft of the engine transmission to change the direction of power transmission, thereby increasing the reverse function; three-wheeled motorcycles and miniature Four-wheel agricultural vehicle all adopts that reverse gear is installed on the engine speed changer equally and realizes the motion of reverse gear. [0003] And small car is when climbing or running on the poorer road surface of running condition, and the normal driv...

AI Technical Summary

Problems solved by technology

[0003] And small car is when climbing or running on the poorer road surface of running condition, and the normal driving condition of small motor vehicle can't satisfy, therefore, need to carry out afterburning; Agricultural vehicles) generally use afterburner devices to meet the above requirements, and afterburner devices are generally installed on the rear axle to obtain greater transmission force

[0004] It can be seen from the above structure that the reverse gear and afterburner are to install the reverse gear and afterburner gearbox on the engine part and the rear axle part of the vehicle respectively, and the reverse gear and afterburner of the vehicle are realized by two transmission units. The chain length increases, the power consumption increases, and the mechanical efficiency decreases; the reverse gear and the afterburner transmission are respectively installed in two places of the vehicle, the installation and maintenance operations increase, and the installation layout is relatively scattered, taking up a large space, and the installation and maintenance are economical. also relatively high
