Abstract
The invention relates to a full-time four-wheel drive chassis of a small-displacement passenger car. The design of the existing automobile differential shell with a unilateral gear is changed, the automobile differential shell is designed to be a device with gears on both a left differential shell and a right differential shell, the left side of the device is enabled to be engaged with a power output shaft gear of a differential to transmit power to front wheels, and the right side of the device is enabled to be engaged with a power output shaft gear to transmit the power to rear drive wheels through a transmission shaft. The original transfer case or the original inter-axle differential is omitted and the chassis is a simpler and lighter four-wheel drive chassis device.
Description
Affiliated technical field:
A kind of float amount four-wheel drive vehicle driving device
Background technology:
Present automobile differential shell all is monolateral design of gears, so four-wheel drive vehicle can only adopt " part-time case " or " interaxle differential " device, could give front and back wheel the power distribution of change-speed box; " coupling apparatus " in past is out of use now, just can work because " coupler " has only under the situation of tyre skidding, and engineering reliability is poor.But because four-wheel drive vehicle all is the vertical driving engine of putting, chassis structure is compact inadequately, often causes vehicle bigger, and manoevreability and traveling comfort are all poor; Though liter-car manoevreability and comfortable relatively good, because " chassis is too light " often caused " chassis is beaten and waftd " phenomenon when running at high speed, influenced the normally handling of vehicle.
Summary of the invention:
Think in " physics ": when an object was in high-speed motion state, its center was moved after can be hastily ...Liter-car is owing to all be the before driving design; In running at high speed because the effect of air-flow, wherein the heart hastily after when moving, make front driving wheel lose and the due adhesive ability in ground; Just making people feel " chassis is beaten and waftd ", is not what " chassis is too light " is caused.If make the liter-car trailing wheel become drive wheel, just there has not been " moving behind the center " problem in four wheel drive yet, and the SUV performance of little discharge capacity has been proved fully.
Concrete embodiment: at first, liter-car is a transverse engine, the shell on the left and right both sides on its preceding diff all is designed to gear-like: be designed to cylindrical wheel and change-speed box power take-off shaft gear mesh to the left side, delivered to front-wheel to power; Secondly, become conical gear and power take-off shaft (that is: rear driving axle power input shaft) gear mesh to the right diff enclosure designs; At last, connect power take-off shaft through transmission shaft power is transported to rear drive sprocket, thereby realized the purpose of four wheel drive.
The purpose of invention is: the not fuel-efficient technical matters that will make liter-car fundamentally overcome " chassis is beaten and waftd " of automobile with small output volume why, and can not be to increase the weight solve problem on chassis.So; Omitted the driving device of consistent " part-time case " or " interaxle differential " that adopts of present four opinion driving cars in the design; Take directly to deliver to the way that front-wheel, trailing wheel get on to power, make chassis layout lighter and handier from change-speed box, and; Four wheel drive can improve liter-car to ground-surface adhesive ability, thus keep its run at high speed in the stationarity on chassis and handling.
Its useful effect is: transverse engine, four wheel drive make float amount manned vehicle that good manoevreability and traveling comfort promptly arranged; Possessed the stationarity on the chassis of running at high speed and handling again; Reach the technical requirements of " little discharge capacity, lightweight, high-speed " modern automobile, also could really reach the purpose of saving fuel oil.

The specific embodiment:
1. diff shell before producing according to drawing technology; 2. be assembled into them " Transaxle " device of speed change and differential one; 3. the driving engine that disposes little discharge capacity is horizontal on vehicle frame; (4) injecting preceding diff to the front-wheel semiaxis is connected on the front-wheel; Transmission shaft connects rear driving axle and flows to trailing wheel to power.
Claims (2)
1. the differences of float amount manned vehicle full-time four wheel drive chassis and present four opinion driving cars: be that it has omitted " part-time case " or " interaxle differential " device (comprising " coupler " device in the past) that uses on the present four wheel drive chassis; But directly delivered to the four-wheel drive vehicle that front and rear wheel goes to the power of change-speed box; Not only grip of the wheel is very strong, and on chassis structure, becomes very light and handy.
2. other characteristic is: present automobile differential shell all is monolateral design of gears; And float amount manned vehicle four wheel drive chassis all has been designed to the gear type shape to preceding differential left, right casing both sides; Left side shell and change-speed box power take-off shaft gear mesh have been delivered to front-wheel to power through left and right half; Right casing and the engagement of another power take-off shaft are delivered to rear driving axle to power again through transmission shaft, are that a kind of very simple four opinions drive the chassis form.
