Description

Minitype wheeled loader

One, technical field:

The utility model relates to the loader that uses in the industries such as building, transportation, mine, machinery, more particularly is minitype wheeled loader.

Two, background technology:

Existing loader is divided into large-scale and small-sized two kinds, and supporting capacity is a two-wheel drive at the small sized loader below 1 ton entirely, promptly only has the forerunner or has only rear-guard.For example ZLY06 type small capacity double is driven loader and is mainly comprised transmission system, hydraulic pressure tipping bucket system, machine frame system and control system, this transmission system mainly by motor, speed changer, power transmission shaft (as the forerunner: have only front propeller shaft; Rear-guard: have only inter-axle shaft), main reducing gear (forerunner: have only preceding main reducing gear; Rear-guard: have only rear primary gearbox), tire is formed; Therefore the power of this speed changer is unidirectional output, promptly has only single output shaft, and above-mentioned small capacity double is driven loader and had following shortcoming: shovel material ability is low, and is lower to the shovel capacity power than heavy material; Climbing capacity is low, and its climbable gradient is less than 20 degree.

Three, summary of the invention:

The purpose of this utility model is exactly that a kind of minitype wheeled loader that can overcome the prior art deficiency will be provided, the utility model shovel capacity power height, and climbing capacity is strong, and is easy to maintenance, long service life.

In order to achieve the above object, technical solution of the present utility model is: existing small capacity double is driven (promptly having only forerunner or rear-guard) loader and change small-sized 4 wheel driven wheel loader into; Change the power output of speed changer in the transmission system into double output shaft by single output shaft, also increased a power transmission shaft and a main reducing gear; Double output shaft in this speed changer links with preceding main reducing gear, rear primary gearbox respectively by front propeller shaft, inter-axle shaft.

This speed changer comprises I axle, II axle, III axle, IV axle, power dual output V axle, is the level Four speed change; The speed change high gear of paying on gear on this I axle and the II axle is meshed, on this III axle pay the speed change shifting slide gear can with the II axle on pay the speed change high gear, pay a speed change low-speed gear and be meshed, thereby realize the high, low speed conversion; II-V shelves gear on this III axle, IV-VI shelves gear and I-III shelves gear can be meshed with II-V shelves shifting slide gear and the I-III-IV-VI shelves shifting slide gear on the IV axle, the speed change shifting slide gear of paying on the III axle is meshed with deceleration gear wheel on the V axle by the reduction pinion teeth on the IV axle then, power is exported by dual output V axle, thereby realizes 3 advance at utmost speed shelves and 3 low-forward range; The speed change high gear of paying on gear on this I axle and the II axle is meshed, pair speed change low-speed gear on this II axle is meshed with the II-V shelves shifting slide gear on the IV axle, be meshed with deceleration gear wheel on the V axle by the reduction pinion teeth on the IV axle then, power is realized 1 reverse gear by the output of dual output V axle.

Compared with the prior art the utility model has the following advantages and good effect.The utility model is small-sized 4 wheel driven wheel loader, and is simple in structure, easy to maintenance, economical and practical; Shovel material, shovel capacity power are all very strong, can be used for heavier on the complex road surface, than the shovel fortune of the close material of matter.With drive loader with the small capacity double of power and compare, tractive force is big, climbing capacity is strong, climbable gradient is increased to 60 degree by 20 original degree; Operating efficiency is doubled, for example shovel fortune 1M ³Building stones, existing small capacity double drive loader need be with 10 minutes, and the utility model only need be with 5 minutes.Because the component of whole drive system more than 80% all adopt general part, realization standardization, though therefore type of drive changes 4 wheel driven into by two driving, manufacturing cost but increases seldom, and economic results in society but obviously increase.The utility model can be widely used in builing industry, transport service, mine, builds water conservancy projects, farmland construction, the carrying of mechanical industry short-distance and medium-distance ground.
